Invasive alien species are a big global problem. They play a major role in global biodiversity loss. They have come to stay and here we show you why
Vanbergen, A.J., et al. 2018. Risks to pollinators and pollination from invasive alien species. Nature ecology & evolution, 2(1), p.16.
Invasive species are non-native or non-indigenous species which have the ability to spread beyond their native range, increase in population size and cause potentially adverse effects. It is important to note that many non-native species found across various environments are not invasive because they lack the ability to increase in population size and spread rapidly.. In comparison to invasive species, non-native species being introduced into a new community are not necessarily a problem. For example, sometimes non-indigenous species are purposely introduced into a new community for agricultural reasons, such as to kill a pest.. Conversely, invasive species are an issue. For one, invasive species can cause fluctuations in community structure and thus, disrupt the functioning of the population. Secondly, invasive species can cause the extinction of native species. Extinction can result from the spread of diseases, competition or hybridization, to name a few possibilities.. In order for non-native ...
We review direct and indirect impacts of invasive alien species (focussing on plants and insects) on native bees worldwide. Although there is a rapidly growing body of research into the effects of invasive alien plants on native plant pollination via disruption of native mutualisms, there has been little research on the impacts of invasive alien plants directly on bees. Such impacts are likely to vary according to the taxon of plant, the functional specificity of the native bees, and ecosystem context. Conversely, there have been more attempts to document impacts of invasive alien social bees on native bees. Most of these studies only indirectly evaluate competition for resources, have focused on a few native species and findings are sometimes contradictory. However, some studies showed strong negative impacts, suggesting that effects might be species-specific. Additionally, pathogen spillover and reproductive disruption due to interspecific mating has been demonstrated among some closely ...
B.1 General background The Millennium Ecosystem Assessment (2005) designated invasive alien species (IAS), alongside climate change, habitat destruction, pollution and overexploitation, as one of the main causes of global biodiversity loss. Alien (or non-native, non-indigenous, foreign, exotic, introduced) species (AS) are defined by the Convention on Biological Diversity (CBD) as a species, subspecies or lower taxon (such as a variety, race, provenance or stock), introduced outside its natural past or present distribution, which includes any part, gametes, seeds, eggs, or propagules of such species that might survive and subsequently reproduce where introduction refers to the movement by human agency, indirect or direct, of an alien species outside of its natural (past or present) range (COP 6, decision VI/23) and invasive alien species (IAS) as an alien species whose introduction and/or spread threaten biological diversity (COP 6, decision VI/23). This COST Action will align to these ...
Invasive plant species have long been known to cause extensive damage, both economically and ecologically, to native ecosystems. They have historically been introduced by the public, both intentional and not, for a variety of reasons. Many of the woody shrubs, such as Lonicera maackii and Rosa multiflora were introduced for wildlife cover, forage, and ornamental value. These invasives have quickly out-competed native flora, in many cases drastically impacting and changing the environment they inhabit. In this review, chosen species characteristics have been described, their pathway to invasion explained, and their impacts to native wildlife highlighted. Based on a review of the scientific literature, we determined that not all effects by invasive plants are negative. Many positive impacts can be seen throughout the literature, such as native frogs utilizing Microstegium vimineum for cover and nesting habitat. However, some important invasive plant species were not included in this review due to a lack
Invasive species are animals, plants, parasites or disease-causing organisms that establish themselves outside their natural range and become pests.
Introduction. The negative consequences of invasion by alien species - a global problem1 - have been acutely felt in South Africas Cape Floristic Region (CFR), which is noted for its high levels of biodiversity and endemism among plants and freshwater fish.2,3 South Africas response to this threat has come in the form of a large, national-scale programme that seeks to simultaneously control invasive alien species and to provide employment opportunities among poor rural communities.4,5 This programme was focused initially on the control of invasive alien plants, for which R3.2 billion was spent over 15 years.6 Its mandate has more recently been expanded to cover the control of invasive species from all taxonomic groups, with an increased budget of almost R1 billion per year.7 While some concerns have been raised about the effectiveness of these interventions,6,8 it is also widely recognised that careful planning and effective implementation can and have resulted in previously heavily invaded ...

The Animal and Plant Health Agency (APHA) was launched on 1 October 2014. It merges the former Animal Health and Veterinary Laboratories Agency (AHVLA) with parts of the Food and Environment Research Agency (FERA) responsible for plant and bee health to create a single agency responsible for animal, plant and bee health. We work to safeguard animal and plant health for the benefit of people, the environment and the economy.. An enthusiastic Non-native Species Specialist is required to provide technical guidance and delivery support primarily to UK Government in delivery of domestic policy on invasive non-native species (INNS) and its obligations under existing European Union Regulation on the prevention and management of the introduction and spread of invasive alien species.

This will range from research into risks posed ...
Contingency planning can be targeted for certain key pests that are clearly a threat and for which an entry pathway can be identified.. One of the most important characteristics of Australia s management of pest incursions is that frequently it begins offshore. Pre-border regional collaboration is an important means of understanding what the pest threats are and then mitigating those threats. Building plant protection capacity in neighbouring countries, electronic communication networks and collaborative research projects all contribute to Australia s assessment of immediate pest risks and careful targeting of post-border surveillance for particular organisms.. Surveillance is an essential element in preventing the establishment or spread of exotic pests, through early detection and managing the response to detections, and supporting trade where it depends on pest free status. Surveillance may be general, where information on pests is gathered from many sources, or it may take the form of ...

Biological invasions as drivers of biodiversity loss have recently been challenged. Fundamentally, we must know where species that are threatened by invasive alien species (IAS) live, and the degree to which they are threatened. We report the first study linking 1372 vertebrates threatened by more than 200 IAS from the completely revised Global Invasive Species Database. New maps of the vulnerability of threatened vertebrates to IAS permit assessments of whether IAS have a major influence on biodiversity, and if so, which taxonomic groups are threatened and where they are threatened. We found that centres of IAS-threatened vertebrates are concentrated in the Americas, India, Indonesia, Australia and New Zealand. The areas in which IAS-threatened species are located do not fully match the current hotspots of invasions, or the current hotspots of threatened species. The relative importance of biological invasions as drivers of biodiversity loss clearly varies across regions and taxa, and changes ...
LOOKS CAN BE DECEIVING! Invasive species look beautiful, unique, and harmless and to too many, they look great in a garden or fish tank. They shouldnt be fooled. Invasive species are non-native organisms that take over native habitats. They cause severe damaging effects to ecosystems of native plants and animals.. The following lesson plan will help third through fifth graders to distinguish between native versus invasive species. They will look at the impacts of invasive species on native ecosystems, and learn strategies to minimize those impacts. You can harness your students enthusiasm to protect endangered species by discussing ways in which people can help endangered animals through the removal or prevention of invasive species. At the conclusion of the lesson, the students will make their own public service announcement video about invasive species and explain what people can do to address this global biodiversity issue - and share it with the school.. ...
Of the 7,000 estimated non-native species present in North America, approximately 1,000 are invasive. Clearly, invasive species are in the minority, but their small numbers dont keep them from causing billions of dollars in economic and ecological harm each year. Policymakers and ecologists continue to try to figure out which species might be harmful, which invasive species are doing the most damage, and which of these might respond best to eradication efforts.
Phosphorus has always been a big part of just about any water-quality discussion, including those about its levels in the Great Lakes. It also intersects with another big ecological problem in the lakes: invasive species.

Invasive alien species are regarded as one of the top five threats to biodiversity and scientists believe a stronger approach is needed to properly manage them.
The conservation threat represented by invasive species is well-known, but the scientific opportunities are underappreciated. Invasion studies have historically been largely directed at the important job of collecting case studies. Invasion biology has matured to the point of being able to
Invasive species often lack predators in new environments, which promotes their success in new habitats. Exotic organisms disrupt ecosystems by outcompeting other species and acting without environmental constraints. Therefore, invasive species have a directly negative effect on biological diversity because they reduce the populations of native and endemic species and have even driven species to extinction. According to NatureServe, invasive species may compete directly with native species for food or space, may compete indirectly by changing the food web or physical environment, or may prey on or hybridize with native species (Conservation Issues). One example of the success of an invasive species in a new environmental is the overwhelming prosperity of the European Rabbit, or common rabbit, in Australia. Introduced in 1859, the common rabbit experienced exponential growth due to its high fecundity and lack of predators, and their presence resulted in soil erosion and significant species loss ...
Invasive plant species are threatening native plants and animals across the U.S. by blocking out sunlight and hogging nutrients and water. These infestations cover about 100 million acres and are costing the U.S. billions of dollars in agricultural losses.
Fungi are one of the most important and highly diverse organisms. Although some attention has been given to species with interest for conservation biology, such as endangered or invasive alien species, none of these have been examined systematically.. In the present paper, the authors seek to assess the endemicity of Japanese fungi using GBIF-mediated data. Endemic species are unique to a given geographic location, such as an island, country or other defined area. Categorizing a species as endemic should be limited to well-known species to avoid falsely classifying due to lack of data. Proving the endemicity of a species is difficult, if not impossible. Primary biodiversity data, however, makes it easy to confirm the occurrence of a species in an overseas location and thereby ruling out endemicity.. By examining two volumes of Colored Illustrations of Mushrooms of Japan (I and II) (Imazeki and Hong 1987, 1989), a masterpiece of mycobiota information, researchers reviewed the comments of 3,928 ...

At local scales, native species can resist invasion by feeding on and competing with would-be invasive species. However, this relationship tends to break down or reverse at larger scales. Here, we consider the role of native species as indirect facilitators of invasion and their potential role in this diversity-driven invasion paradox. We coin the term native turncoats to describe native facilitators of non-native species and identify eight ways they may indirectly facilitate species invasion. Some are commonly documented, while others, such as indirect interactions within competitive communities, are largely undocumented in an invasion context. Therefore, we use models to evaluate the likelihood that these competitive interactions influence invasions. We find that native turncoat effects increase with the number of resources and native species. Furthermore, our findings suggest the existence, abundance and effectiveness of native turncoats in a community could greatly influence invasion ...

AU - Vandenbruwaene, Wouter. AU - Temmerman, Stijn. AU - Zhang, Li Quan. AU - Herman, Peter M.J.. PY - 2016. Y1 - 2016. N2 - Species invasions are known to change biotic and abiotic ecosystem characteristics such as community structure, cycling of materials and dynamics of rivers. However, their ability to alter interactions between biotic and abiotic ecosystem components, in particular bio-geomorphic feedbacks and the resulting landscape configuration in tidal wetlands, such as tidal channels have not yet been demonstrated. We studied the impact of altered bio-geomorphic feedbacks on geomorphologic features (i.e. tidal wetland channels), by comparing proxies for channel network geometry (unchanneled flow lengths, fractal dimension) over time between non-invaded and invaded salt marsh habitats. The non-invaded habitats (the ...
Introduction of a species outside its native range is all that is required to be qualified as an introduced species such that one can distinguish between introduced species that may not occur except in cultivation, under domestication or captivity whereas others become established outside their native range and reproduce without human assistance. Such species might be termed naturalized, established, wild non-native species. If they further spread beyond the place of introduction and cause damage to nearby species, they are called invasive. The transition from introduction, to establishment and to invasion has been described in the context of plants.[6] Introduced species are essentially non-native species. Invasive species are those introduced species that spread widely or quickly and cause harm, be that to the environment,[7] human health, other valued resources, or the economy. There have been calls from scientists to consider a species invasive only in terms of their spread and ...
Invasive species can dramatically impact natural populations, especially those living on islands. Though numerous examples illustrate the ecological impact of invasive predators, no study has examined the genetic consequences for native populations s
Invasive species pose a significant threat to natural resources in the U.S. They can dramatically alter local ecosystems by decreasing biodiversity, out-competing and displacing native plants and animals and threatening endangered species. Because invasive species can spread rapidly, collaboration among states is essential.
Invasive species are prolific non-native plants or animals that, when introduced to an ecosystem, may imbalance the system and disrupt its natural functioning. Biologists at Bielefeld University in the team of junior professor Dr. Christiane Werner in cooperation with the University of Lisbon have developed non-invasive method for quantifying the spatial impact of such exotic species on the ecosystems which they invade.
Invasion ecology has been criticised for its lack of general principles. To explore this criticism, we conducted a meta-analysis that examined characteristics of invasiveness (i.e. the ability of species to establish in, spread to, or become abundant in novel communities) and invasibility (i.e. the susceptibility of habitats to the establishment or proliferation of invaders). There were few consistencies among invasiveness characteristics (3 of 13): established and abundant invaders generally occupy similar habitats as native species, while abundant species tend to be less affected by enemies; germination success and reproductive output were significantly positively associated with invasiveness when results from both stages (establishment/spread and abundance/impact) were combined. Two of six invasibility characteristics were also significant: communities experiencing more disturbance and with higher resource availability sustained greater establishment and proliferation of invaders. We also found that
WASHINGTON, April 2, 2014-The U.S. Department of Agriculture (USDA) today proclaimed April as Invasive Plant Pest and Disease Awareness Month. Each year during April, USDA amplifies its public outreach about the risks that invasive plant pests, diseases and harmful weeds pose to Americas crops and forests-and how the public can prevent their spread. These non-native, destructive species can seriously harm the economy, environment, or even human health.. Invasive species threaten the health and profitability of U.S. agriculture and forestry, and the many jobs these sectors support, said Kevin Shea, Administrator of USDAs Animal and Plant Health Inspection Service (APHIS). To protect that crucial value, USDA and its partners work hard every day to keep invasive pests and diseases out of the United States and to control those that may slip in. This April, were asking all Americans to be our partners in this critical work.. Invasive plant pests and diseases can jeopardize entire industries ...
In the beginning, restoration of the farm faced several major landscape issues. First, the farm was heavily grazed by cattle for close to 75 years. This grazing pressure led to limited biodiversity in the open fields, severe erosion of the two distinct watersheds on the property, and prevalence of invasive plant species. Additionally, overabundance of white-tailed deer in the area caused the degradation of ground vegetation and sapling trees in the woodlands of the property, decreasing biodiversity even further. As restoration progressed, other issues appeared, particularly the pressure of invasive plant species on the meadow restorations and the pressures of surrounding suburban development.. In order to deal with the eroded waterways and incised streams, Woltz and his team designed small pools at the headwaters of the streams to slow water flow (with the added benefit of providing habitat for amphibians) (Figure 1). They used filtration strips and shrub plantings to stabilize the stream banks. ...

The movement of species, ranging in size from microscopic organisms such as viruses or bacteria to plants to large animals, has always been part of life on Earth. Some of it happens naturally through migration patterns, weather and other factors. Humans, however, have been responsible for extensive artificial movement of large numbers of species for some time, due to their economic and social activities throughout the world. In recent years, technological advancements and increases in world trade have led to even more intentional and unintentional movement of species to habitats where they are not native, sometimes with disastrous results. While there are times when the intentional introduction of alien species improves quality of life (such as food production or biocontrol), the misuse of alien species has caused serious ecological and economic harm. When alien species become established in a new habitat, they can disrupt the existing balance of that ecosystem. In some cases, the new species ...
Invasive plant species are like the common cold: Theyre easily caught, undesirable and if left untreated, can lead to something much more serious. Across Iowa, a variety of species threaten our native ecosystems. These weeds dominate and choke out wild and native plants, leading to less diverse native natural areas. The following are five of the most common and threatening invasive species in Iowa.
Many introductions have been viewed as providing economic and /or social benefits to humans. However, from the beginning of the 1970s, the ideology began gradually to change to considering any introduction or invasion as harmful to natural biological diversity (Vilwock, 1971; Vooren, 1972). Now, the ability of nonindigenous species to alter population and community structure and function is well documented. Ecosystem-level consequences of some invasive species have major ecological and economic implications. Sometimes, invasive species are able to spread to and proliferate in new habitats because of their tolerance for a wide range of environmental conditions, much wider than that in their native distribution. They usually also demonstrate diverse diet, aggressive behavior, long spawning period, ability to spawn repeatedly or to markedly increase absolute and relative fecundity, larger body size compared with species of a similar lifestyle. The group of the most harmful species includes ...

My research interests center on the ecology and evolution of plant-herbivore-natural enemy interactions. This stems from both an applied interest in the biological control of plant pests by natural enemies and a theoretical interest in the behavior, population dynamics and persistence of species comprising ecological communities. In my research program, I advocate a spatial approach to understanding these trophic interactions. My current research interests focus on four broad areas.. 1. Biogeography of plant invasions. I am particularly interested in the factors that influence invasion success over broad-geographic and temporal spatial scales. My research focuses on the invasive grass, Phragmites australis. We have explored the effects of latitude, natural enemies (i.e., herbivores, pathogens), higher trophic levels, soil microorganisms, plant genetics (ploidy, genome size, and genotypic variation), plant defensive chemistry, and climate change on invasion success and interactions with other ...
Invasive Indo-Pacific lionfish (Pterois volitans) have rapidly expanded in the Western Atlantic over the past decade and have had a significant negative impact on reef fish biodiversity, habitat, and community structure, with lionfish out-competing native predators for resources. In an effort to reduce this population explosion, lionfish have been promoted for human consumption in the greater Caribbean region. This study examined whether the geographical expansion of the lionfish into a known ciguatera-endemic region can pose a human health threat for ciguatera fish poisoning (CFP). More than 180 lionfish were collected from waters surrounding the US Virgin Islands throughout 2010 and 2011. Ciguatoxin testing included an in vitro neuroblastoma cytotoxicity assay for composite toxicity assessment of sodium-channel toxins combined with confirmatory liquid chromatography tandem mass spectrometry. A 12% prevalence rate of ciguatoxic lionfish exceeding the FDA guidance level of 0.1 µg/kg C-CTX-1 equivalents
TY - JOUR. T1 - The impact of the invasive alien plant, impatiens glandulifera, on pollen transfer networks. AU - Emer, Carine. AU - Vaughan, Ian P.. AU - Hiscock, Simon. AU - Memmott, Jane. PY - 2015/12/3. Y1 - 2015/12/3. N2 - Biological invasions are a threat to the maintenance of ecological processes, including pollination. Plant-flower visitor networks are traditionally used as a surrogated for pollination at the community level, despite they do not represent the pollination process, which takes place at the stigma of plants where pollen grains are deposited. Here we investigated whether the invasion of the alien plant Impatiens glandulifera (Balsaminaceae) affects pollen transfer at the community level. We asked whether more alien pollen is deposited on the stigmas of plants on invaded sites, whether deposition is affected by stigma type (dry, semidry and wet) and whether the invasion of I. glandulifera changes the structure of the resulting pollen transfer networks. We sampled stigmas of ...

Author Summary The Asian tiger mosquito, Aedes albopictus, is a highly invasive mosquito and has spread from South East Asia to Europe, the United States and northern areas of Asia in the past 30 years. Aedes mosquitoes transmit a range of viral diseases, including dengue and chikungunya. Aedes albopictus is generally considered to be somewhat less of a concern in this regard than Aedes aegypti. However a recent mutation in the chikungunya virus dramatically increased its transmission by Aedes albopictus, causing an important outbreak in the Indian Ocean in 2006 that eventually reached Italy in 2007. This highlights the potential importance of this mosquito, which can thrive much further from the Equator than can Aedes aegypti. This paper describes the first genetic engineering of the Asian tiger mosquito. This is an essential step towards the development of genetics-based control methods against this mosquito, and also an invaluable tool for basic research. We describe both transposon-based and site

Aims Although biological invasions occur throughout the world, and some invaders are widespread in many habitats, few studies on the ecological impact of invaders have examined multiple sites. We tested how the impact of three widespread plant invaders changed depending on the identity of the species and the invaded island. We also tested whether relative species loss was lower in species-rich communities than in species-poor ones. Location We conducted floristic surveys and soil analyses in eight Mediterranean Basin islands: Crete and Lesbos (Greece), Sardinia (Italy), Corsica, Bagaud and Porquerolles (France), and Mallorca and Menorca (Spain). Methods We compared native species richness and diversity, proportion of life forms, soil percentage nitrogen, percentage organic carbon, C/N, and soil pH in nearby paired plots of 2 × 2 m: one control and one invaded by either the deciduous tree Ailanthus altissima, the succulent subshrubs Carpobrotus spp. or the annual geophyte Oxalis pes-caprae, ...
An Introduced or Alien species means a species, subspecies, or lower taxon occurring outside of its natural range (past or present) and dispersal potential (i.e. outside the range it occupies naturally or could not occupy without direct or indirect introduction or care by humans) and includes any part, gametes or propagule of such species that might survive and subsequently reproduce. An Invasive Alien Species is an alien species which becomes established in natural or semi-natural ecosystems or habitat, is an agent of change, and threatens native biological diversity. In GRIIS, species are recorded as having an impact (as yes under isInvasive) if there is evidence of the species negatively impacting biodiversity, and including species that are widespread, spreading rapidly or present in high abundance (Pagad et al. 2018). This usage is relevant to the purpose of GRIIS, and consistent with the concept of impact as formulated by Parker et al. (1999) and now widely used (e.g. Didham et al. ...
The Asian tiger mosquito, Aedes albopictus, is a highly successful invasive species that transmits a number of human viral diseases, including dengue and Chikungunya fevers. This species has a large genome with significant population-based size variation. The complete genome sequence was determined for the Foshan strain, an established laboratory colony derived from wild mosquitoes from southeastern China, a region within the historical range of the origin of the species. The genome comprises 1,967 Mb, the largest mosquito genome sequenced to date, and its size results principally from an abundance of repetitive DNA classes. In addition, expansions of the numbers of members in gene families involved in insecticide-resistance mechanisms, diapause, sex determination, immunity, and olfaction also contribute to the larger size. Portions of integrated flavivirus-like genomes support a shared evolutionary history of association of these viruses with their vector. The large genome repertory may ...

CITY NEWS SERVICE. EL MONTE - An aggressive species of mosquito responsible for outbreaks of dengue virus in Florida, Hawaii and Texas has been found in El Monte, officials said Tuesday.. Asian tiger mosquitoes are aggressive biters and active during daylight hours, as well as at dusk and dawn, according to the San Gabriel Valley Mosquito and Vector Control District, the agency responsible for mosquito control in the area.. Our goal is to eradicate this population, said Kenn Fujioka, the districts assistant manager. We definitely do not want this mosquito to become established in our communities.. The black-and-white striped insect, about a quarter-inch long, is a native of tropical and subtropical Southeast Asia and has not been seen in the San Gabriel Valley since 2001, when they were accidentally imported in shipments of plants called Lucky Bamboo.. The pest can transmit many serious diseases, including dengue fever, yellow fever; chikungunya, which is similar to dengue fever; ...

Invasive alien species are a major threat to native insular species. Eradicating invasive mammals from islands is a feasible and proven approach to prevent biodiversity loss. We developed a conceptual framework to identify globally important islands for invasive mammal eradications to prevent imminent extinctions of highly threatened species using biogeographic and technical factors, plus a novel approach to consider socio-political feasibility. We applied this framework using a comprehensive dataset describing the distribution of 1,184 highly threatened native vertebrate species (i.e. those listed as Critically Endangered or Endangered on the IUCN Red List) and 184 non-native mammals on 1,279 islands worldwide. Based on extinction risk, irreplaceability, severity of impact from invasive species, and technical feasibility of eradication, we identified and ranked 292 of the most important islands where eradicating invasive mammals would benefit highly threatened vertebrates. When socio-political ...
Of all the diverse insects, mites and diseases affecting the coconut palm, only some emerge as threats due to their invasive and injurious nature. Endemic organisms emerge as threats due to factors such as climate change, evolution of pesticide resistance as well as virulence matching host resistance. Generally, these threats are mostly short- medium-term since the respective countries have devised their own management practices over time. Movement of alien invasive species across national borders is a potential global threat to humans, agricultural production, indigenous ecosystem, and animal and plant health and gaining more and more attention in view of increasing travel and trade among countries To protect the coconut industry coconut growing countries worldwide must share the responsibility of finding solutions to cope with the risks and impact of emerging plant pests and diseases, particularly the introduction of invasive alien species..

Several Australian Acacias have become invasive when introduced into new areas within Australia. These invasive Acacias may have a detrimental effect on native flora and induce changes to below-ground microbial composition. Previous studies have shown that the invasive success of Acacias can be at least partly attributed to their ability to associate with N-fixing rhizobial bacteria. This study assessed the role of rhizobia in the invasion success of four Acacia species (A. cyclops, A. longifolia, A. melanoxylon, A. saligna) and closely related species Paraserianthes lophantha in their nonnative environment within Australia. Presence or absence of rhizobia in soils in both the native and introduced ranges of each species, as well as infectivity and efficacy, were estimated using the Most Probable Number (MPN) method to determine numbers of rhizobial cells/g-1 of soil. A glasshouse experiment had shown that there are significant differences in aboveground biomass between plants grown in soils ...
With global warming effects - higher temperatures and the fast ice melting in the planet - there are more and more sensitive areas to the arrival of non-native invasive species. These phenomena are especially worrying in areas such as the Antarctic Peninsula, where environmental conditions could favor the survival of the potentially invasive species. The Antarctic Peninsula is the most vulnerable area to the episodes of biological invasions through drifting waters. The geographical latitude, and closeness to terrestrial areas - South America, Scotia Arch islands, etc. - with potentially invasive species, the position of the coasts regarding the Antarctic Circumpolar Current, and the climate conditions are factors that would favor the arrival and colonizing success of non-native species carried by algae or plastics, notes Àvila, head of the research projects Bluebio, Distantcom, Ecoquim and Actiquim, on the ecology of marine invertebrate communities in Antarctic waters.. The risk of invasion ...
NSW Department of Primary Industries (DPI) is undertaking re-snagging works to improve native fish habitat in the Lower Severn River.. The reintroduction of snags - part of a collaborative project between DPI Fisheries and the Northern Tablelands Local Land Services (LLS) - aims to boost habitat for small and large native fish, including some threatened species.. Recent mapping has identified a low number of snags in parts of the Severn River, said NSW DPI Fisheries Manager Charlie Carruthers.. Snags are fallen trees or boulders that are a major ecological and structural element of our waterways.. They increase in-stream habitat for native fish by providing hiding and resting places out of the main flow of the river as well as spawning sites for several species of native fish, including popular recreational species such as Murray Cod, he said.. Snags also play an important role in the food webs of our waterways with small aquatic animals such as shrimp feeding on the algae that grow on ...
Native Fish and Amphibians From Fish Stocking SACRAMENTO, Calif.- The Sacramento Superior Court has ordered the California Department of Fish and Game into talks with Pacific Rivers Council and the Center for Biological Diversity to develop interim measures to limit harm to native species caused by fish stocking. The intent is to minimize the adverse effect that hatchery-raised fish inflict on sensitive native fish and amphibian species while the Department prepares an Environmental Impact Report under the California Environmental Quality Act.. Interim measures limiting stocking are needed to help save Californias native fish and frogs from extinction, said Noah Greenwald, biodiversity program director for the Center for Biological Diversity. Fish and Game should still be able to stock hatchery fish, but in places where they wont harm native species.. The court ruled in May 2007 that fish stocking has significant environmental impacts on aquatic ecosystems and in particular, on native ...
Tree planting is the best action to take in order to mitigate deforestation and tree removal. However care must be taken not to unwittingly harm the environment. One may ask how is it possible to harm the environment by planting trees?. There are many non-Armenian tree species (non-native species), which are invasive and can aggressively occupy an area by crowding out and eventually replacing native, indigenous species of trees. Unfortunately, in Armenia, after the massive tree-cutting period of the early 1990s the planting of invasive species became a common practice, mostly due to lack of awareness of the ecological detriment that planting of invasive species can cause.. Below is a partial list of trees and shrubs which are growing in Armenia. We generally recommend planting only species that are labeled as native. Any species labeled invasive should never be planted and actually should be removed whenever possible. These invasive species have a particular ability to produce thousands and ...
The Goriška region and the town of Nova Gorica itself are a hotspot for reproduction and further spreading of many plant or animal non-native species. The reason for this are its transitional position and its mild climate. In recent years an invasive species known as the tiger mosquito (Aedes albopictus Skuse, 1894) has colonized this area. Here it successfully reproduces and maintains its population. In this paper we studied the seasonal dynamics of its reproduction from the appearance of first eggs until the development of the species larvae in various urban, suburban and forested locations. We studied the presence of tiger mosquito larvae in different surroundings and tried to determine its most suitable microhabitat. In order to acquire appropriate results we used ovitraps, which are commonly used to monitor mosquito larvae in their natural environment. At the end we examined the ratio between larvae of indigenous species and tiger mosquito larvae. The data were compared to shed light on ...

The Aedes albopictus (Asian Tiger) mosquitoes which can transmit Zika, Chikungunya, and Dengue Fever viruses, have adapted very well to human habitats, by being able to lay eggs that survive long periods without water and that can hatch and grow into larvae after a rain shower in a container as small as a bottle cap. Differing greatly in habitat from the more familiar marsh mosquitos that thrive near marshes in tidal zones, the Asian Tiger mosquitos, with recognizable white striped legs, feeds during daylight hours when people are most likely to be outside, versus the marsh mosquitoes that primarily feed at dusk.. There are many things that families on the Eastern Shore of Virginia can do to protect themselves from mosquitos on their own property and in their community:. 1.

Abstract: Invasive plants frequently have competitive advantages over native species. These advantages have been characterized in systems in which the invading species has already become well established. Surprisingly, invader impacts on native communities currently undergoing invasion are lacking from most ecological studies. In this work we document and quantify shifting patterns in plant community structure in a native ecosystem (remnant tallgrass prairie) undergoing invasion by the invasive exotic Sorghum halepense (Johnsongrass). Further, we use manipulative field and greenhouse studies to quantify impacts of potential allelochemicals contained in whole-plant S. halepense leachates on growth of the dominant native grass, Schizachyrium scoparium (Little Bluestem), and tested the inhibitory effects of the potential soil legacy of S. halepense on the native grass in the greenhouse. Plant diversity indices revealed three distinct plant communities within the remnant prairie: a native community, ...
When exotic species spread over novel environments, their phenotype will depend on a combination of different processes, including phenotypic plasticity (PP), local adaptation (LA), environmental maternal effects (EME) and genetic drift (GD). Few attempts have been made to simultaneously address the importance of those processes in plant invasion. The present study uses the well-documented invasion history of Senecio inaequidens (Asteraceae) in southern France, where it was introduced at a single wool-processing site. It gradually invaded the Mediterranean coast and the Pyrenean Mountains, which have noticeably different climates. We used seeds from Pyrenean and Mediterranean populations, as well as populations from the first introduction area, to explore the phenotypic variation related to climatic variation. A reciprocal sowing experiment was performed with gardens under Mediterranean and Pyrenean climates. We analyzed climatic phenotypic variation in germination, growth, reproduction, leaf physiology

Abstract : European overseas territories are home to biodiversity and endemism of worldwide importance, vastly superior to that of continental Europe as a whole. They are, however, much more threatened by invasive species, including hundreds of alien invasive plant species having a huge impact on natural and agricultural habitats. As in continental Europe, invasive plants have only recently been recognized as a threat to the local environment and biodiversity. Mechanical and chemical control programmes - underway for several decades - have not been entirely successful for permanent, cost effective, environment-friendly management. Biological control of weeds has long been successfully used in other neighbouring countries with similar climates, environmental conditions and invasions, but has barely been implemented in European overseas territories. There have been very few attempts to set up cIassical biological control programmes in these regions - a few of the species that have been the focus ...

maples replace them. Control Level Diagnosis: Medium priority. While Acer platanoides is a relatively new threat to established forests, the convergence of increasing forest fragmentation through urban sprawl and the accelerating invasion of Norway maples into established forests could quickly tip the balance and complete its penetration of the forest in the northeastern US, and possibly elsewhere. Meanwhile, the trees continue to sell well in the nursery trade and to be introduced ever more broadly. Norway maples are popular on the commercial ornamental tree market -- two Norway maple cultivars ranked among the top six nursery offerings in the northeastern U.S. throughout the 80s (Norwalk and Sydnor 1992). The fact that they grow quickly and are easy to propagate makes them favorites of growers and nursery owners, and the fact that they transplant well, grow quickly, and are tolerant of many tough conditions makes them favorites of buyers as well.

  • Introducing EzTaxon-e: a prokaryotic 16S rRNA gene sequence database with phylotypes that represent uncultured species. (nih.gov)
  • The 16S rRNA gene has been used extensively for this task when coupled with a well-curated database, such as EzTaxon, containing sequences of type strains of prokaryotic species with validly published names. (nih.gov)
  • Examples of these terms are acclimatized , adventive , naturalized , and immigrant species but those terms refer to a subset of introduced species. (wikipedia.org)
  • Adventive species: Often considered synonymous with "introduced species", but this term is sometimes applied exclusively to introduced species that are not permanently established (that is, not naturalized). (wikipedia.org)
  • Naturalized species are introduced species that do not need human help to reproduce and maintain their population in an area outside their native range (no longer adventive). (wikipedia.org)
  • A real evolutionary change in the fundamental niche would be proposed for those cases in which similar climatic background exists in native-introduced areas and the species is actively selecting different climatic spaces 18 . (nature.com)
  • The impact of introduced species is highly variable. (wikipedia.org)
  • El objetivo de este estudio fue evaluar la estructura poblacio-nal (abundancia, estructura de tallas, relación talla-peso, proporción de sexos , y talla de primera madurez) y el período reproductivo de estas dos especies en la represa Santa Cruz, (construida en el 2002), situada en la región semiárida de Brasil .
