Amphibians are declining globally, and infectious disease is one of their primary threats. Ranaviruses infect cold-blooded vertebrates, with FV3-like ranaviruses being associated with amphibian mortality events across much ...

A large body of research has documented evolutionary change in fish populations as a result of selective harvest, a process known as Fisheries-Induced Evolution (FIE). Much of this research has focused on commercially-harvested ...

The Illinois chorus frog (Pseudacris illinoensis) is a fossorial species found only in sandy substrates of Illinois, Missouri, and Arkansas. The genetic diversity of the Illinois chorus frog (ICF) in Illinois has not been ...

Although progress has been made, we are still a long way from being able to predict and understand the dynamics of demographically “open” aquatic populations. Even though we often have a good understanding of events and ...

The post-fledging period—defined as the time between when a bird leaves its nest and disperses or migrates—is a critical stage in the avian life cycle. Past research has identified survival during this stage as a key ...

The effect of multiple stressors on global water resources have been increasing rapidly over the past few decades. Anthropogenic activities such as rapid industrialization, urbanization, deforestation and increased application ...

Invasive bighead (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix) have become established throughout much of the Mississippi River basin. In many areas, these two species comprise a significant ...

Island systems serve as important models for studies of evolutionary processes and speciation. The Hawaiian Island group is one of the most isolated island chains in the world, and many groups of insects have undergone ...

As part of the Critical Trends Assessment Program (CTAP) of the Illinois Department of Natural Resources, 18 potential reference quality stream reaches in the Grand Prairie Natural Division were evaluated in May 2004 and ...

The Conservation Reserve (CRP) and Conservation Reserve Enhancement Programs (CREP), funded by federal and state government, offer farmers financial incentives to take erosive agricultural lands out of production. Within ...
