Measuring Wetland Restoration Success through Water Quality and Invertebrate Community Indices

Wetland restoration projects are essential to preserving these imperiled ecosystems. While restoring lost or degraded wetlands is the first step, determining the success of these restoration efforts is often difficult or only focuses on one aspect of an ecosystem (e.g., water quality testing). I plan to measure the success of wetland restoration through traditional (i.e., water quality testing) and non-traditional methods (i.e., terrestrial and aquatic insect sampling) in native (i.e., control) and restored (i.e., experimental) wetlands in Ohio. I will use sweep nets for aboveground insect collection and a dip net for aquatic macroinvertebrate collection. These samples will be sorted, counted, and identified (to at least the family level) in the lab, where we will determine how terrestrial insect and aquatic macroinvertebrate community indices (e.g., Shannon diversity, richness, evenness) indicate the health of restored wetlands. Water quality testing will be performed using a YSI probe, measuring dissolved oxygen, pH, conductivity, temperature, and nitrates. The values collected for these characteristics will be compared to native wetlands and known standard water health metrics. By combining traditional (i.e., water quality testing) with non-traditional sampling techniques, the results of this project will provide a novel method to determine the health of restored wetlands. Using these results, we will be able to work with and advise local soil and water conservation districts how best to invest their money and resources for wetland preservation. This project will be essential for the health of our wetlands in Ohio

The Genome Sequence of Taurine Cattle:A Window to Ruminant Biology and Evolution

To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.Fil: Bovine Genome Sequencing and Analysis Consortium.
