A distinguishing characteristic of prokaryotes was long thought to be the lack of a cytoskeleton similar to eukaryotes consisting of actin filaments, microtubules, and intermediate filaments. However, recent work has shown ...

Submerged macrophytes affect many aspects of lotic ecosystems, including nutrient dynamics. We performed longitudinal vegetation surveys to describe the distribution of macrophytes in Big Spring Creek, Wisconsin. We also ...

Development of residential lakeshore properties can have several effects on aquatic ecosystems including the thinning of littoral coarse woody habitat. Previous studies have shown that reduction of littoral coarse woody ...

Mothers of many species find great comfort in their offspring, which in turn has been found to alleviate mild stress in the mother. In the face of a life-threatening event, however, do offspring still act as effective ...

Zic genes encode proteins that contain zinc fingers used to bind DNA and modify transcription of target genes. Several zic genes have been identified that are critical in regulating nervous system development in a wide ...

This project aims to further our understanding of developmental genetics by identifying unknown transcription factor binding sites that play an important role in regulating zic2a, a gene required for proper neural development ...

San Felipe is a small fishing village on the Caraquez estuary on the coast of Ecuador. Only twenty years ago, this community was able to sustain itself on clam collecting, but due to poor management and mangrove destruction, ...

A central question in biology is how different cell-types arise from an initially one-celled embryo to form an organism. Many cellular differences arise through differential gene expression in space and time via the action ...

Within the past century, the copepod Eurytemora affinis have invaded freshwater from saline sources throughout the Northern Hemisphere. Two genetically divergent clades (Atlantic and North Atlantic) of E. affinis coexist ...
