Perspective on eastern migration studies: Stopover ecology of migratory landbirds in the Gulf Coast region

Millions of Nearctic-Neotropical landbirds move through the coastal habitats of the Gulf of Mexico each spring and autumn as they migrate across and around the Gulf. Migration routes in the Gulf region are not static and they shift year to year and season to season according to prevailing wind patterns. Using data from field and radar studies, we mapped patterns of migration movement and landfall

A simple technique for trapping Siren lacertian, Amphiuma means, and other aquatic vertebrates

We describe a commercially-available funnel trap for sampling aquatic vertebrates. The traps can be used in heavily vegetated wetlands and can be set in water up to 60 cm deep without concern for drowning the animals. They were especially useful for capturing the aquatic salamanders Siren lacertina and Amphiuma means, which have been difficult to capture with traditional sampling methods. They als

The effectiveness of a barrier wall and underpasses in reducing wildlife mortality on a heavily traveled highway in Florida

Because of high numbers of animals killed on Paynes Prairie State Preserve, Alachua County, Florida, the Florida Department of Transportation constructed a barrier wall-culvert system to reduce wildlife mortality yet allow for passage of some animals across the highway. During a one year study following construction, we counted only 158 animals, excluding hylid treefrogs, killed in the same area w

Effects of invasive alien plants on fire regimes

Plant invasions are widely recognized as significant threats to biodiversity conservation worldwide. One way invasions can affect native ecosystems is by changing fuel properties, which can in turn affect fire behavior and, ultimately, alter fire regime characteristics such as frequency, intensity, extent, type, and seasonality of fire. If the regime changes subsequently promote the dominance of t

Survival estimates for Florida manatees from the photo-identification of individuals

We estimated adult survival probabilities for the endangered Florida manatee (Trichechus manatus latirostris) in four regional populations using photoidentification data and open-population capture-recapture statistical models. The mean annual adult survival probability over the most recent 10-yr period of available estimates was as follows: Northwest - 0.956 (SE 0.007), Upper St. Johns River - 0.

Capture-recapture analysis for estimating manatee reproductive rates

Modeling the life history of the endangered Florida manatee (Trichechus manatus latirostris) is an important step toward understanding its population dynamics and predicting its response to management actions. We developed a multi-state markresighting model for data collected under Pollock's robust design. This model estimates breeding probability conditional on a female's breeding state in the pr
