They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.

Predicted changes in the intensity and frequency of climate extremes urge a better mechanistic understanding of the stress response of microbially-mediated carbon and nutrient cycling processes. This study is the first comprehensive study of the resistance and resilience of microbial C, N, and P cycling processes in decomposing plant litter to severe temperature disturbances. Disturbances led temporarily to a more rapid cycling of C and N but caused a down-regulation of P cycling. In contrast to the fast recovery of C and N processes, we found a slow recovery of P mineralization rates. The functional and structural responses to the two distinct temperature disturbances were markedly similar, suggesting that direct negative physical effects and costs associated with the stress response were comparable. This study provides novel insights into the mechanisms of microbial functional stress responses and illustrates the need for a closer integration of microbial C-N-P interactions into climate ...

Low-temperature anaerobic digestion (LTAD) presents a sustainable, cost-efficient technology for the treatment of a vast array of wastewater streams. However, this microbially-mediated process requires further understanding and experimental characterisation if large-scale application of LTAD is to be realised. The objective of this thesis was to employ a functional-based approach to characterise the microbial communities underpinning low-temperature anaerobic digestion. Firstly, the key microbial functional groups present in end-point samples taken from three, laboratory-scale, expanded granular sludge bed (EGSB) bioreactors; R1 (37°C), R2 (15°C) and R3 (7°C) were characterised. Metaproteomics, in conjunction with 16S rRNA gene phylogenetic approaches (clone libraries, qPCR), was applied to record microbial community composition and metaproteomic profiles as a function of bioreactor operating temperature. Clone libraries indicated a predominance of the Chloroflexi (21%) and ¿-Proteobacteria ...
DNA and RNA-based sequencing of the 16S rRNA gene and transcripts were used to assess the phylogenetic diversity of microbial communities at assets experiencing corrosion in an oil production facility. The complementary methodological approach, coupled with extensive bioinformatics analysis, allowed to visualize differences between the total and potentially active communities present in several locations of the production facility. According to the results, taxa indicative for thermophiles and oil-degrading microorganisms decreased their relative abundances in the active communities, whereas sulfate reducing bacteria and methanogens had the opposite pattern. The differences in the diversity profile between total and active communities had an effect on the microbial functional capability predicted from the 16S rRNA sequences. Primarily, genes involved in methane metabolism were enriched in the RNA-based sequencing approach. Comparative analysis of microbial communities in the produced water, injection
Leibold and Chase have written an authoritative and accessible account of recent research on how spatially organized processes shape patterns of biological diversity over the ecological landscape. This book will be the springboard for future work in this area.-Robert E. Ricklefs, University of Missouri, St. Louis. Current thinking in ecology is a disorganized soup of ideas, from dispersal and spatial heterogeneity to temporal change, species sorting, and evolution. This book impressively pulls these disparate threads into a powerful and coherent framework based on metacommunities. Its next-generation metacommunity framework could well serve as a launching pad for the next decade of ecology.-Brian McGill, University of Maine. In this magisterial book, Leibold and Chase provide a conceptually coherent synthesis of the burgeoning field of metacommunity ecology. In addition to deftly synthesizing a sprawling literature on the role of dispersal limitation, drift, and interactions in ...
Most studies of microbial communities in which 16S rRNA sequences are used rely on standard estimates of diversity (i.e., the Shannon-Weiner index). This approach is informative, but it ignores important information about the disparity among the sampled sequences. In this study I used standard quantitative methods of analysis borrowed from population genetics and systematics for describing and comparing microbial communities. Information gained from analysis of DNA sequences provided the basis for statistical analysis of communities in ways that advance inferences about the processes that may govern the compositions and functions of microbial communities. Furthermore, the analytical approaches advocated here make it possible to accomplish broad comparisons of ecological communities. For instance, a comparison of lineage-per-time plots across a diverse set of ecosystems might reveal differences in the phylogenetic compositions of ecological communities that would be invisible with standard ...

ABSTRACT: The literature on the ecology of marine assemblages includes frequent examples of data analysis with no well-defined alternative hypotheses for the definition of environmental variables (independent matrix for multivariate methods). Alternative models, whereby spatial or temporal patterns are investigated, should be explicitly assumed. We present a parsimonious procedure for model selection in multivariate data combined with canonical correspondence analysis to determine the measure of explained variance for each tested model, using Akaike¹s information criterion (AIC) for model selection. The AIC procedure is an effective tool for model selection and, in contrast to other conventional procedures that use only 1 implicit model and ignore other community patterns, it provides a framework for ranking hierarchical patterns that adds an alternative non-disjunctive perspective to assemblage analysis. Hierarchical patterns are revealed as layers in a scale-dependent framework. ...

The team found that their samples from both Maine and the Namib contained a diverse microbial community, featuring a mix of both soil-based and ocean-based microbes. As one might expect, the proportion of marine to terrestrial microbes shifts depending on how close to the ocean the fog is - more marine microbes directly on the coast in Maine, fewer 30 miles inland in the Namib desert.. On the journey from the ocean to the land, microbes not only survive, but change during transport, said Dueker. Fog itself is a novel, living ecosystem.. Microbes that ride fog droplets tend to live longer than those that live in ordinary air, and are more readily safely deposited on land. The presence of fog changes the lands existing microbial community, shifting the fogs benefits and detriments for plants and animals.. Most of the microbes that the researchers found in the fog are totally harmless to humans, but knowing that fog is a conduit for microbes does present possibilities for research on ...
The oldest convincing evidence of life is in 3.5 Ga rocks in the Pilbara region of WA and the Barberton Mountainland of South Africa. Diverse microbial communities lived in environments ranging from volcanic calderas to open marine settings. There is tenuous evidence for life in 3.8-3.9 Ga rocks of Greenland, but the record is obscured by the pervasive alteration of all known rock successions of this age and older. Thus there are no known well preserved rocks older than 3.5 Ga - so, no convincing fossil record. The best we can do at present is to infer the earliest stages of life from studies of extant organisms and from theoretical and experimental approaches to the origin of life.. The oldest known macroscopic organisms preserved in the rock record are dated at 2.1 Ga. Their affinities are obscure, but they may have been algae. There is chemical evidence for eukaryotes (nucleated sexually reproducing organisms) back to 2.7-2.8 Ga, and tentative morphological evidence at 3.0 Ga or even ...

What are fairy rings? Fairy rings are circular areas of abnormal turf growth that are most commonly found on lawns and golf courses where soils have high levels of organic matter, and in areas where trees have recently been removed. Due to their mysterious, circular appearance, fairy rings have been of interest since ancient times. According to medieval lore, they were thought to appear after a band of fairies had danced in an area.. What do fairy rings look like? Fairy rings are rings of grass up to 15 feet in diameter that have a distinctly different color or texture than the grass inside or outside of the ring. Half- or other partial ring patterns occur as well. Depending on conditions, grass within fairy rings can be denser, greener, and faster growing, or alternatively browner and drier than surrounding grass. During wet weather, rings of mushrooms may form at the edge of the discolored grass.. Where do fairy rings come from? Fairy rings are caused by certain fungi that feed on decaying ...

A central challenge in microbial community ecology is the delineation SGX-145 of appropriate models of biodiversity which can be taxonomic phylogenetic or functional in nature. is often not obvious. An analysis that considers taxon task and characteristics in concert may be ideal with the strengths of each approach offsetting the SGX-145 weaknesses of the other. Individual genes also merit concern as entities in an ecological analysis PB1 with characteristics such as diversity turnover and interactions modeled using genes rather SGX-145 than organisms as entities. We identify some promising avenues of research that are likely SGX-145 to yield a deeper understanding of microbial communities that shift from observation-based questions of Who is there? and What are they doing? to the mechanistically driven question of How will they respond? is seen as a leading indicator of a general decline in biodiversity in part due to their sensitivity to disturbances in both terrestrial and aquatic ...

Recently, the use of SADs to test biodiversity theory has been criticized because different species abundance models often generate very similar predictions, which can be difficult to distinguish when fitted to species abundance data (9). Consequently, some researchers have focused on other properties of assemblages, such as community similarity (12), species-area and species-time relationships (23, 24), and relationships between species traits or phylogeny and species abundance (25, 26). Such approaches are powerful when evaluating the performance of particular species abundance models. However, because models combine multiple assumptions, attributing a models failure to one assumption in particular, such as species equivalence, is problematic. Indeed, in the debate over neutral theory of biodiversity, studies that show failure of a neutral model (12, 25, 27) are almost invariably followed by responses showing that packaging neutrality with a different set of alternative assumptions can ...

How resources are being used to fund the community response to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) is of considerable interest to the donor community and governments. In the past decade, international funding for the HIV and AIDS response provided by governments rose from about US$1 billion to US$8.7 billion; donors increasingly shifted their financial support toward funding community responses to this epidemic. Yet little is known about the global magnitude of these resource flows and how funding is allocated among HIV and AIDS activities and services. Although some studies have been carried out to gather information on the community response by civil society organizations (CSOs), most of them provide only partial information limited to a specific intervention (for example, orphan support) or specific local communities. To address this knowledge gap, the report attempts to answer the following questions: How large is donor funding for
Community structure is one of the most relevant features encountered in numerous real-world applications of networked systems. Despite the tremendous effort of a large interdisciplinary community of scientists working on this subject over the past few years to characterize, model, and analyze communities, more investigations are needed in order to better understand the impact of their structure and dynamics on networked systems. The primary goal of this collection is to showcase the cutting edge research advances on community structures in networks, in order to provide a landscape of research progresses and application potentials in related areas ...
In the Ecosystem Modeling research group, we pursue the understanding of the processes underlying the origin, maintenance and spatiotemporal dynamics of biodiversity across scales, from local to global, and across levels of ecological organization, from individuals, over populations, species, communities, and metacommunities up to biomes. The working group applies a range of methods, including field work, data analyses and macroecology, but focuses on mechanistic simulation modeling. The developed mechanistic models for virtual life can be used for theory testing, improving empirical sampling designs, understanding complex process interactions, and predicting biodiversity response to drivers and environmental change scenarios. ...
The biological communitys response to these questions has been to resist design absolutely. The worry is that for natural objects (unlike human artifacts) the distinction between design and non-design cannot be reliably drawn. Consider, for instance, the following remark by Darwin in the concluding chapter of his Origin of Species : Several eminent naturalists have of late published their belief that a multitude of reputed species in each genus are not real species; but that other species are real, that is, have been independently created . . . . Nevertheless they do not pretend that they can define, or even conjecture, which are the created forms of life, and which are those produced by secondary laws. They admit variation as a vera causa in one case, they arbitrarily reject it in another, without assigning any distinction in the two cases. Biologists worry about attributing something to design (here identified with creation) only to have it overturned later; this widespread and legitimate ...

Abstract: Fresh fruits and vegetables can harbor large and diverse populations of bacteria. However, most of the work on produce-associated bacteria has focused on a relatively small number of pathogenic bacteria and, as a result, we know far less about the overall diversity and composition of those bacterial communities found on produce and how the structure of these communities varies across produce types. Moreover, we lack a comprehensive view of the potential effects of differing farming practices on the bacterial communities to which consumers are exposed. We addressed these knowledge gaps by assessing bacterial community structure on conventional and organic analogs of eleven store-bought produce types using a culture-independent approach, 16 S rRNA gene pyrosequencing. Our results demonstrated that the fruits and vegetables harbored diverse bacterial communities, and the communities on each produce type were significantly distinct from one another. However, certain produce types (i.e., ...
Multiyear comparisons of bacterioplankton succession reveal that environmental conditions drive community shifts with repeatable patterns between years. However, corresponding insight into bacterioplankton dynamics at a temporal resolution relevant for detailed examination of variation and characteristics of specific populations within years is essentially lacking. During 1 year, we collected 46 samples in the Baltic Sea for assessing bacterial community composition by 16S rRNA gene pyrosequencing (nearly twice weekly during productive season). Beta-diversity analysis showed distinct clustering of samples, attributable to seemingly synchronous temporal transitions among populations (populations defined by 97% 16S rRNA gene sequence identity). A wide spectrum of bacterioplankton dynamics was evident, where divergent temporal patterns resulted both from pronounced differences in relative abundance and presence/absence of populations. Rates of change in relative abundance calculated for individual ...
Global change drivers (GCDs) are expected to alter community structure and consequently, the services that ecosystems provide. Yet, few experimental investigations have examined effects of GCDs on plant community structure across multiple ecosystem types, and those that do exist present conflicting patterns. In an unprecedented global synthesis of over 100 experiments that manipulated factors linked to GCDs, we show that herbaceous plant community responses depend on experimental manipulation length and number of factors manipulated. We found that plant communities are fairly resistant to experimentally manipulated GCDs in the short term (,10 y). In contrast, long-term (≥10 y) experiments show increasing community divergence of treatments from control conditions. Surprisingly, these community responses occurred with similar frequency across the GCD types manipulated in our database. However, community responses were more common when 3 or more GCDs were simultaneously manipulated, suggesting ...
ABSTRACT: Epilithic bacterial communities play a major role in biogeochemical cycles of rivers; however, distributional patterns and controls of epilithic communities remain unclear. The objective of the present study was to examine possible environmental factors that affect longitudinal distributional patterns of epilithic bacterial communities in 2 rivers (Yasu and Ado Rivers) draining the Lake Biwa basin, Japan. Phylogenetic analyses were conducted using denaturing gradient gel electrophoresis (DGGE) of 16S rRNA genes and fluorescence in situ hybridization (FISH) with oligonucleotide probes targeted to small subunit rRNA. Non-metric multidimensional scaling and canonical correspondence analysis of the DGGE profile indicated that a clear shift in community composition occurred at the middle reach of the Yasu River. This shift was most closely related to variation in the nitrogen stable isotope ratio (δ15N) of epilithic materials (BIOENV analysis, ρw = 0.512), which is an indicator of the ...

The University of Tennessee Anthropology Research Facility (ARF) is well known for its unique history as a site of human decomposition research in a natural environment. It has been integral to our understanding of the processes of human decomposition. Over the last 30 years 1,089 bodies have decomposed at this 1.28 acre facility, producing a density of 850 corpses per acre of land. This project evaluated the abiotic and biotic characteristics of the soil exposed to various levels of human decomposition in order to determine the effect on the physicochemical properties and the indigenous bacterial communities. Specifically, 75 soil samples were taken to determine abiotic properties. A biological matrix was generated for the 40 samples inside the facility based on sequencing of the 16S rDNA gene. The identified taxonomy was evaluated for differences among decomposition bins and taxa. Results of the abiotic soil properties demonstrated few differences among the predefined bins of decomposition density.
The study provides insights into the dynamic processes of vascular epiphyte vegetation in two host tree species of lowland forest in Panama. Further, a novel approach is presented to examine the possible role of host tree identity in the structuring of vascular epiphyte communities: For three locally common host tree species (Socratea exorrhiza, Marila laxiflora, Perebea xanthochyma) we created null models of the expected epiphyte assemblages assuming that epiphyte colonization reflected random distribution of epiphytes in the forest. In all three tree species, abundances of the majority of epiphyte species (69 – 81 %) were indistinguishable from random, while the remaining species were about equally over- or underrepresented compared to their occurrence in the entire forest plot. Permutations based on the number of colonized trees (reflecting observed spatial patchiness) yielded similar results. Finally, a Canonical Correspondence Analysis also confirmed host-specific differences in ...

The representation of ecological communities as networks of interacting species is currently a particularly widespread approach in community ecology. The prevalence of networks has led to a broad literature that sheds light on the links between ecological network structure and stability, the explanatory role of traits and evolutionary history with regard to interaction patterns, and the persistence and dynamics of networks across time and space. In addition to the long-established study of trophic and competitive interactions, the importance of networks of positive interactions to ecological communities is also becoming increasing apparent. Despite these many advances, it is often sidestepped that each interaction network---be it a food-web, pollination network, or host-parasite network---is but one component in a greater, connected whole. That is, each and every ecological community is actually composed of multiple interaction networks that do not operate independent from one another. Indeed, ...

The topology of ecological communities is structured through the many and varied interactions active in food webs [1]. Direct trophic interactions, mutualism, competition, commensalism and parasitism are all modes that interconnect various elements of a community and to a certain extent, govern overall ecosystem dynamics [2]. There is also a growing realization that there are subtler, indirect effects in play [3,4] where third-party actors can be subsumed to play the role of a bait or a protector. The interaction of direct and indirect effects is most evident in so-called intra-guild predation, a tri-trophic arrangement where a consumer and its predator share a common resource [5]. While ecological communities are often described by the topology of the connections among species, their dynamics are controlled by the strength of the interactions these connections represent [6]. Further, the strength of these interactions is not static. Whatever the architecture of ecological communities, the ...
This fundraising campaign is focused on helping the Community Ecology Institute have the operational resources needed to transform our new urban farm into an innovative asset for the community. We have recently hired a part-time Executive Director and look forward to being able to bring Dr. DAmore on full time as well hire additional staff to develop and lead community programs and education opportunities. The operational needs of running a farm are also substantive and this particular property is a diamond in the rough that needs a lot of TLC to bring it into its full potential. Monthly sustaining donations are especially helpful as we seek to develop a steady operating budget. Please consider making a pledge today to support CEI monthly for the next year. If 250 people gave $20.20/month as a part of our 20:20 Visionaries team we would make our $60,000 goal for the year.

Community structures are quite common in real networks. Social networks include community groups (the origin of the term, in fact) based on common location, interests, occupation, etc.[5][6] Finding an underlying community structure in a network, if it exists, is important for a number of reasons. Communities allow us to create a large scale map of a network since individual communities act like meta-nodes in the network which makes its study easier.[7] Individual communities also shed light on the function of the system represented by the network since communities often correspond to functional units of the system. In metabolic networks, such functional groups correspond to cycles or pathways whereas in the protein interaction network, communities correspond to proteins with similar functionality inside a biological cell. Similarly, citation networks form communities by research topic.[1] Being able to identify these sub-structures within a network can provide insight into how network function ...

The requirements for longitudinal evenness of newly constructed road surfaces in Belgium are expressed in the Evenness Coefficient (EC) defined as half of the surface between the profile as obtained from measurements with the Analyseur de Profil en Long (APL) and a curve representing the ideal profile calculated by a sliding average method. Requirements can be expressed in the gap height measured with the three-metre straightedge (TMS) but the acceptance of road works is often based on APL data. When requirements are not matched, the contractor must improve the longitudinal evenness after road works completion. Contractors and road administrations want to exploit APL data fully. This contribution discusses the finesses of longitudinal evenness measurements using APL, EC and TMS. A case study illustrates to what extend the APL data can be exploited. A road section with high unevenness was investigated by APL and TMS, and the geometrical unevenness of the road surface was measured ...

My long-term interests are in the evolution of biological complexity, such as that apparent in complex life histories, in intimate interactions among species and in species-diversity of clades and communities. My focus is on symbiosis, particularly that between multicellular hosts and microbes. Symbioses are central in the evolution of complexity; have evolved many times and are critical to the lifestyles of many animals and plants and also to whole ecosystems, in which symbiotic organisms are key players. The primary reason that symbiosis research is suddenly active, after decades at the margins of mainstream biology, is that DNA technology and genomics give us enormous new ability to discover symbiont diversity, and more significantly, to reveal how microbial metabolic capabilities contribute to the functioning of hosts and biological communities. My ongoing projects, mostly collaborations with students and postdoctoral associates, include phylogenetic and genomic studies of previously ...
Author summary Dynamic changes in microbial communities play an important role in human health and disease. Specifically, deciphering how microbial species in a community interact with each other and their environment can elucidate mechanisms of disease, a problem typically investigated using tools from community ecology. Yet, such methods require measurements of absolute densities, whereas typical only provide estimates of relative abundances. We investigate methods for describing microbial dynamics in terms of relative abundances using approaches from machine learning and dynamical systems. Across three real datasets, we show that relative abundances are sufficient to describe compositional dynamics. Additionally, we show that models trained on relative abundances alone predict future compositions as well models trained on absolute abundances. Finally, we provide criteria for when direct effects, which typically can only be learned from absolute abundances, are recoverable for relative data. As a

Basalts are recognized as one of the major habitats on Earth, harboring diverse and active microbial populations. Inconsistently, this living component is rarely considered in engineering operations carried out in these environments. This includes carbon capture and storage (CCS) technologies that seek to offset anthropogenic CO2 emissions into the atmosphere by burying this greenhouse gas in the subsurface. Here, we show that deep ecosystems respond quickly to field operations associated with CO2 injections based on a microbiological survey of a basaltic CCS site. Acidic CO2-charged groundwater results in a marked decrease (by ~ 2.5-4) in microbial richness despite observable blooms of lithoautotrophic iron-oxidizing Betaproteobacteria and degraders of aromatic compounds, which hence impact the aquifer redox state and the carbon fate. Host-basalt dissolution releases nutrients and energy sources, which sustain the growth of autotrophic and heterotrophic species whose activities may have consequences on
