Using network clustering to predict copy number variations associated with health disparities
… and Caucasians in the United States. Copy number variations (CNVs) are one form of human genetic variations that have been linked with complex diseases and often occur at different frequencies among African Americans and Caucasian populations. In this study, we aimed to investigate whether CNVs …

Identification and isolation of microsatellite loci from the Trematode Echinostoma Trivolvis for use in interspecific and intraspecific variation studies
<p>The aim of this project was to study the population genetics of Echinostoma trivolvis, a parasitic trematode that uses multiple hosts in its lifecycle and has a significant impact on amphibian populations. Microsatellite markers were to be identified and isolated because of their highly variable …

Seasonal variation in the reproductive biology of the ring -billed gull (Larus delawarensis)
The reproductive biology of the Ring-billed Gull (Larus delawarensis) was studied on Gull Island, Presqu'ile Provincial Park, Ontario, in 1976 and 1977. Early started clutches (comprising the majority of clutches on Gull Island) in 1977 produced more chicks per nest (2.20 ± 0.09) than late started …

Effect of Pollution on Genetic Diversity in the Southern California Bight
<p>Two intertidal invertebrate species, <em>M galloprovincialis</em> and <em>Balanus glandula</em>, were collected from seven different bay sites along the Southern California coast to test if environmental contamination is associated with the decrease of genetic diversity at the population level. …

Fatty Acids as Biomarkers of Plankton Trophic Structure in Table Rock Lake, Missouri
Recently, fatty acid profiles have been used as an alternative to stable isotopes for measuring trophic linkages in freshwater food webs. An advantage of fatty acids is that many different compounds can be resolved and most of these are conserved, providing a "signature” of different food resources …
