Grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), and silver carp (H. molitrix), are three species of Asian carp that were intentionally introduced into the United States in the 1960s and 70s ...

The western corn rootworm (WCR; Diabrotica virgifera virgifera LeConte) is an important chrysomelid pest of corn (Zea mays) in the US. WCR larvae feed on corn roots, while adult beetles may consume aboveground corn tissues. ...

Landscape change in the Midwest, USA has resulted in drainage of most wetlands and isolated those that remain. Semiaquatic species occurring in this region must adapt to novel landscapes and mortality risks and variable ...

Agricultural intensification has negatively affected biodiversity throughout the world. In the U.S., population declines of many early successional bird species have been linked with habitat loss due to agriculture. One ...

Studying the ecology of terrestrial turtle species provides understanding of their spatial needs. Radio-telemetry was used to study the home range size, movement, habitat use, and nesting of Terrapene carolina. Minimum ...

Several environmental stressors can impact the physiology and survival of fishes. Fish experience natural fluctuations in temperature and dissolved oxygen, but variations in these parameters due to anthropogenic sources ...

The single greatest concentration of endemic life in the United States, and second greatest in North America, can be found 90 miles northwest of Las Vegas, Nevada in Ash Meadows National Wildlife Refuge. This area is ...

Understanding factors important to recruitment in fishes has proven to be a difficult and challenging problem. Largemouth bass Micropterus salmoides, a popular recreational sport fish, is an excellent model species to ...

Bighead (Hypophthalmichthys nobilis) and silver (H. molitrix) carp (collectively, Asian carp) have invaded the Mississippi River Basin and have successfully established populations in the Illinois River. Correlative studies ...

There must be genetic change both through time and over space for organisms to adapt to local environmental conditions. Gene flow inhibits genetic differences from accumulating over space, while the magnitude of the variance ...
