... 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.

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 ...

TY - JOUR. T1 - On the potential of plant species invasion influencing bio-geomorphologic landscape formation in salt marshes. AU - Schwarz, Christian. AU - Ysebaert, Tom. 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.

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 ...

However, it has no regulatory authority, and should be used with full understanding of the limitations described here.. ...
The same issues we see in the environment (loss of diversity, extinction, and introduction of invasive species) are happening to our own internal ecosystem
A large number of invasive aquatic and terrestrial plant species have become introduced into the United States. While several agencies have developed databases for tracking the locations and status of these invaders, these agencies do not have the resources to thoroughly track the presence and locations of these species in the states, relying instead on voluntary reporting of locations. An important component to a state and regional coordination of management efforts will be an accessible and up-to-date database of invasive species locations and actions to manage them, operated and managed at the regional level. GRI is actively mapping the locations of invasive aquatic and terrestrial plant species in the Midsouth, and entering them into our web-based database for invasive plant species. This database will be developed in collaboration with national USGS and other agency databases and structures, and the Invasive Plant Atlas of New England (IPANE), with mechanisms and procedures in place to ...
