Diabetes Health Stories : Free Clinic Patients.

Color poster with text and tables describing research conducted by Stephanie Vach, Lynn Siefert, and Jeanne Volks, advised by Sheila Smith.Little published research is available regarding the impact of diabetes on patients using free clinics as their primary source of health care. As part of a larger diabetes management project, this study interviewed diabetes patients at the Chippewa Valley Free Clinic regarding their experiences with diabetes and its impact on their lives. Struggles, challenges, successes, health needs, and health goals were explored.University of Wisconsin--Eau Claire Office of Research and Sponsored Programs

Community-wide plasmid gene mobilization and selection.

Plasmids have long been recognized as an important driver of DNA exchange and genetic innovation in prokaryotes. The success of plasmids has been attributed to their independent replication from the host's chromosome and their frequent self-transfer. It is thought that plasmids accumulate, rearrange and distribute nonessential genes, which may provide an advantage for host proliferation under selective conditions. In order to test this hypothesis independently of biases from culture selection, we study the plasmid metagenome from microbial communities in two activated sludge systems, one of which receives mostly household and the other chemical industry wastewater. We find that plasmids from activated sludge microbial communities carry among the largest proportion of unknown gene pools so far detected in metagenomic DNA, confirming their presumed role of DNA innovators. At a system level both plasmid metagenomes were dominated by functions associated with replication and transposition, and contained a wide variety of antibiotic and heavy metal resistances. Plasmid families were very different in the two metagenomes and grouped in deep-branching new families compared with known plasmid replicons. A number of abundant plasmid replicons could be completely assembled directly from the metagenome, providing insight in plasmid composition without culturing bias. Functionally, the two metagenomes strongly differed in several ways, including a greater abundance of genes for carbohydrate metabolism in the industrial and of general defense factors in the household activated sludge plasmid metagenome. This suggests that plasmids not only contribute to the adaptation of single individual prokaryotic species, but of the prokaryotic community as a whole under local selective conditions

A Global Meta-analysis Of The Relative Extent Of Intraspecific Trait Variation In Plant Communities

However, a general picture of the relative extent of ITV compared to interspecific trait variation in plant communities is still missing. Here, we conducted a meta-analysis of the relative extent of ITV within and among plant communities worldwide, using a data set encompassing 629 communities (plots) and 36 functional traits. Overall, ITV accounted for 25% of the total trait variation within communities and 32% of the total trait variation among communities on average. The relative extent of ITV tended to be greater for whole-plant (e.g. plant height) vs. organ-level traits and for leaf chemical (e.g. leaf N and P concentration) vs. leaf morphological (e.g. leaf area and thickness) traits. The relative amount of ITV decreased with increasing species richness and spatial extent, but did not vary with plant growth form or climate. These results highlight global patterns in the relative importance of ITV in plant communities, providing practical guidelines for when researchers should include ITV in trait-based community and ecosystem studies.181214061419National Science Foundation Graduate Research Fellowship [DGE-1247399]NSF [DEB-03089]Marie Curie International Outgoing Fellowship within the 7th European Community Framework Program (DiversiTraits project) [221060]European Research Council (ERC) Starting Grant Project 'Ecophysiological and biophysical constraints on domestication in crop plants' [ERC-StG-2014-639706-CONSTRAINTS]European Research Council under the 7th European Community Framework Program FP7 [281422]Chilean Fondo Nacional de Desarrollo Cientifico y Tecnologico (FONDECYT) project [1120171]Czech Science Foundation [P505/12/1296]Discovery Grants from the Natural Science and Engineering Research Council of CanadaSwiss National Science Foundation [PA00P3_136474, PZ00P3_148261]Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)JSPS as a Postdoctoral Fellow for Research AbroadFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)New Zealand Ministry of Business, Innovation and Employment core fundingMinistry for the Environmentproject Postdoc USB [CZ.1.07/2.3.00/30.0006]European Social FundCzech State BudgetPontifical Catholic University of Ecuadorgovernment of EcuadorAndrew W.

Data from: Habitat filtering determines the functional niche occupancy of plant communities worldwide

How the patterns of niche occupancy vary from species-poor to species-rich communities is a fundamental question in ecology that has a central bearing on the processes that drive patterns of biodiversity. As species richness increases, habitat filtering should constrain the expansion of total niche volume, while limiting similarity should restrict the degree of niche overlap between species. Here, by explicitly incorporating intraspecific trait variability, we investigate the relationship between functional niche occupancy and species richness at the global scale. We assembled 21 datasets worldwide, spanning tropical to temperate biomes and consisting of 313 plant communities representing different growth forms. We quantified three key niche occupancy components (the total functional volume, the functional overlap between species and the average functional volume per species) for each community, related each component to species richness, and compared each component to the null expectations. As species richness increased, communities were more functionally diverse (an increase in total functional volume), and species overlapped more within the community (an increase in functional overlap) but did not more finely divide the functional space (no decline in average functional volume). Null model analyses provided evidence for habitat filtering (smaller total functional volume than expectation), but not for limiting similarity (larger functional overlap and larger average functional volume than expectation) as a process driving the pattern of functional niche occupancy. Synthesis. Habitat filtering is a widespread process driving the pattern of functional niche occupancy across plant communities and coexisting species tend to be more functionally similar rather than more functionally specialized. Our results indicate that including intraspecific trait variability will contribute to a better understanding of the processes driving patterns of functional niche occupancy
