Freshwater mussel survey prior to the Ellsworth Dam removal, Danville, Vermilion County, Illinois
This report is submitted in response to a request from the Illinois Department of Natural Resources (IDNR) for the Illinois Natural History Survey (INHS) to conduct a freshwater mussel survey in the North Fork Vermilion River (Wabash River drainage) in the vicinity of the Ellsworth Dam, Danville, Vermilion County, Illinois. IDNR proposes to remove this dam, and needs updated survey data prior to the removal per the requirements of Authorization item #7 in the Ellsworth Park Dam Removal Incidental Take Authorization. Freshwater mussels were collected by hand-Ââpicking and visual detection (e.g., trails, siphons, exposed shell) in the three zones (Impounded area, Construction zone, and Plunge pool). One live individual was found alive in the construction zone in three person hours, whereas 372 individuals representing ten species were found alive in the impounded area upstream of the construction in approximately 25 person-Ââhours. A total of 46 individuals representing eight species were found alive in the plunge pool in 2.25 person-Ââhours. All species collected are common inhabitants of central Illinois streams that are not listed as endangered or threatened at the state or federal level, and all live individuals were relocated to areas outside the predicted zone of influence.Prepared for Illinois Department of Natural Resources Office of Water Resourcesunpublishednot peer reviewedOpe
Uterine Nodal expression supports maternal immunotolerance and establishment of the FOXP3+ regulatory T cell population during the preimplantation period
Pregnancy success is dependent on the establishment of maternal tolerance during the preimplantation period. The immunosuppressive function of regulatory T cells is critical to limit inflammation arising from implantation of the semi-allogeneic blastocyst. Insufficient maternal immune adaptations to pregnancy have been frequently associated with cases of female infertility and recurrent implantation failure. The role of Nodal, a secreted morphogen of the TGFÎČ superfamily, was recently implicated during murine pregnancy as its conditional deletion (NodalÎ/Î) in the female reproductive tract resulted in severe subfertility. Here, it was determined that despite normal preimplantation processes and healthy, viable embryos, NodalÎ/Î females had a 50% implantation failure rate compared to NodalloxP/loxP controls. Prior to implantation, the expression of inflammatory cytokines MCP-1, G-CSF, IFN-Îł and IL-10 was dysregulated in the NodalÎ/Î uterus. Further analysis of the preimplantation leukocyte populations in NodalÎ/Î uteri showed an overabundance of infiltrating, pro-inflammatory CD11bhigh Ly6C+ macrophages coupled with the absence of CD4+ FOXP3+ regulatory T cells. Therefore, it is proposed that uterine Nodal expression during the preimplantation period has a novel role in the establishment of maternal immunotolerance, and its dysregulation should be considered as a potential contributor to cases of female infertility and recurrent implantation failure
Basics of collaborative research data management: Requirements for a Schleswig-Holstein state initiative on research data management
Das Papier "Grundlagen eines partnerschaftlichen Forschungsdatenmanagements - Anforderungen an eine schleswig-holsteinische Landesinitiative zum Forschungsdatenmanagement" umreiĂt die Anforderungen fĂŒr eine schleswig-holsteinische Landesinitiative zum Forschungsdatenmanagement (FDM-SH). HierfĂŒr wird zunĂ€chst das Umfeld, in dem eine solche Initiative entstehen und agieren soll, beschrieben. So beeinflussen sowohl die Eigenheiten der regionalen Forschungslandschaft wie auch die Entwicklungen im Bereich der Nationalen Forschungsdateninfrastruktur (NFDI) die AusprĂ€gungen von Landesinitiativen. Die speziellen Anforderungen werden durch den Vergleich mit anderen Landesinitiativen, die Analyse von spezifischen Umfrageergebnissen aus Schleswig-Holstein sowie die BerĂŒcksichtigung der Anforderungen der NFDI gesammelt. Der Ansatz des partnerschaftlichen Forschungsdatenmanagements (FDM) spiegelt das Anliegen Schleswig-Holsteins wider, die Herausforderungen fĂŒr ein zeitgemĂ€Ăes FDM vor Ort gemeinsam zu bewĂ€ltigen und dabei sowohl Know-how zu teilen als auch Ressourcen zu schonen
Vom klassischen OPAC zum modernen Rechercheportal : AnsĂ€tze zur EinfĂŒhrung eines Discovery Systems an der ZHB LĂŒbeck
Discovery Systeme basieren auf moderner Suchmaschinentechnologie und verbinden diese mit elektronischen bibliothekarischen Rechercheinstrumenten, wie z.B. den OPAC oder Fachdatenbanken. Sie werden bereits in zahlreichen Bibliotheken verwendet und sollen kĂŒnftig auch an der ZHB LĂŒbeck zum Einsatz kommen. In dieser Arbeit werden AnsĂ€tze zur Einrichtung eines Discovery Systems verfolgt. ZunĂ€chst wird dabei auf die Entwicklungen von bibliothekarischen und internetbasierten Rechercheinstrumenten sowie angrenzenden Themenbereichen grundlegend eingegangen. Es folgt eine Marktsichtung, die neben kommerziellen Resource Discovery Systemen auch Open-Source-Lösungen betrachtet und die Erfahrungen von Bibliotheken anhand von Literaturquellen miteinbezieht. Auf Basis der hier zu Grunde liegenden AusfĂŒhrungen werden die Möglichkeiten der ZHB LĂŒbeck zur EinfĂŒhrung eines Discovery Systems dargelegt. Diskussion und Ausblick runden die Ergebnisse ab

How green is the market? : creating a tool to evaluate the success of the new generation of âgreenâ residential Greenfield development
textAs the population of the United States continues to grow as projected, it is clear that the need for new homes will grow with it. At the same time, there is increasing dissatisfaction with conventional sprawling suburban development. In response to this dissatisfaction, new types of alternative or âgreenâ Greenfield developments are appearing all over the country. What these developments have in common is that they all strive to be better than conventional suburban development; better places to live that are also better for the environment. This report compiles a database of these different developments and their characteristics. Next, it examines if these âgreenâ residential developments are in fact a success in the marketplace. To do this it looks at conventional and innovative real estate evaluation methods. A new evaluation tool that can be used to evaluate the market acceptance of the new generation of âgreenâ Greenfield development is then proposed. Finally, the need for further study including the creation of an evaluation tool to measure the environmental âsuccessâ of these projects is examined.Community and Regional Plannin

Regional biogeography versus intra-annual dynamics of the root and soil microbiome
Background: Root and soil microbial communities constitute the below-ground plant microbiome, are drivers of nutrient cycling, and affect plant productivity. However, our understanding of their spatiotemporal patterns is confounded by exogenous factors that covary spatially, such as changes in host plant species, climate, and edaphic factors. These spatiotemporal patterns likely differ across microbiome domains (bacteria and fungi) and niches (root vs. soil). Results: To capture spatial patterns at a regional scale, we sampled the below-ground microbiome of switchgrass monocultures of five sites spanning &amp;amp;#x003E; 3 degrees of latitude within the Great Lakes region. To capture temporal patterns, we sampled the below-ground microbiome across the growing season within a single site. We compared the strength of spatiotemporal factors to nitrogen addition determining the major drivers in our perennial cropping system. All microbial communities were most strongly structured by sampling site, though collection date also had strong effects; in contrast, nitrogen addition had little to no effect on communities. Though all microbial communities were found to have significant spatiotemporal patterns, sampling site and collection date better explained bacterial than fungal community structure, which appeared more defined by stochastic processes. Root communities, especially bacterial, were more temporally structured than soil communities which were more spatially structured, both across and within sampling sites. Finally, we characterized a core set of taxa in the switchgrass microbiome that persists across space and time. These core taxa represented &amp;amp;#x003C; 6% of total species richness but &amp;amp;#x003E; 27% of relative abundance, with potential nitrogen fixing bacteria and fungal mutualists dominating the root community and saprotrophs dominating the soil community. Conclusions: Our results highlight the dynamic variability of plant microbiome composition and assembly across space and time, even within a single variety of a plant species. Root and soil fungal community compositions appeared spatiotemporally paired, while root and soil bacterial communities showed a temporal lag in compositional similarity suggesting active recruitment of soil bacteria into the root niche throughout the growing season. A better understanding of the drivers of these differential responses to space and time may improve our ability to predict microbial community structure and function under novel conditions
