Juvenile survival is among the most important demographic parameters driving population dynamics in birds. However, because first-year (i.e. 1-year-old) migratory passerines are thought to return to breed at great distances ...

Current declines in shrubland bird populations and habitats in eastern North America highlight the importance of understanding the nesting ecology of shrubland birds. The majority of the literature on shrubland birds has ...

In the past the best models of raindrop shapes were based on a perturbation form of Laplace's formula valid only for small amplitude distortion from the effect of an aerodynamic pressure around a sphere. In contrast, the ...

Habitat loss and fragmentation are the leading threats to biodiversity worldwide. In fragmented landscapes, movement of organisms among patches of suitable habitat is critical to ecological and evolutionary processes. ...

Demographic studies of wildlife populations are needed to guide management decisions for threatened species. Without data on population vital rates, decisions are often speculative and based on general information about a ...

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 ...
