Asian butterfly populations different mimicry patterns genetic 'switch'
2021/1/28
A new study by researchers at the University of Chicago and the City College of New York has identified a unique, genetic "mimicry switch" that determines whether male and female Elymni...

Urbanization, higher temperatures can influence butterfly emergence patterns
2014/5/13
Urbanization and global climate change can profoundly alter biological systems, yet scientists often analyze their effects separately. We test how the timing of life cycle events (phenology) is jointl...

2014/4/1
Zooplankton are not uniformly distributed in space but are patchy at multiple scales as a result of
interactions between their directed motion and both large- and small-scale water currents. Using &#...

Effect of salinity on seasonal community patterns Mediterranean temporary wetland crustaceans A mesocosm study
2014/4/17
In a large-scale outdoor mesocosm experiment we studied the effects of salinity on successional patterns, diversity, and relative abundances of Camargue (southern France) temporary pool crustaceans. E...
Expression Patterns of Germ Cell-specific Phosducin-like 2 during Testicular and Ovarian Development in Chickens
Chickens In situ Hybridization Pdcl2 qRT-PCR
2016/5/5
Phosducin (PDC) is a photoreceptor cell-specific protein that is phosphorylated by cyclic nucleotide-dependent protein kinase. PDC and PDC-like proteins (PDCL, PDCL2, and PDCL3) are members of a conse...
