Ecological Consequences of Recent Climate Change
Global climate change is frequently considered a major conservation threat. The Earth's climate has already warmed by 0.5 8 C over the past century, and recent studies show that it is possible toExpand

Polychlorinated biphenyls and 2,3,7,8-tetrachlorodibenzo-p-dioxin equivalents in tree swallows from the Upper Hudson River, New York State, USA
The upper Hudson River of New York State, USA, is contaminated with polychlorinated biphenyls (PCBs) as a result of industrial discharges throughout the latter half of this century. In 1994 and 1995,Expand

The Energetic Cost of Begging in Nestling Passerines
A critical assumption of many of the current discussions of parent-offspring conflict and sibling competition is that the begging behavior of nestling birds is costly, either in terms of energeticsExpand

Reproductive ecology of tree swallows (Tachycineta bicolor) with high levels of polychlorinated biphenyl contamination
Tree swallows (Tachycineta bicolor) breeding along the Hudson River forage extensively on PCB-contaminated insects that emerge from the river. We studied the reproductive ecology and behavior of treeExpand

Spatial and temporal variation in fruit use by wildlife in a forested landscape
Abstract We monitored production and removal rates of fruit from 22 common plant species over 2 years in five habitats of a managed landscape in South Carolina (USA). Our long-term goal is toExpand

Foraging ecology and diet selectivity of tree swallows feeding nestlings
We studied the foraging ecology of a population of Tree Swallows (Tachycineta bicolor) breeding in New York State over a period of 5 years. While feeding nestlings, adult Tree Swallows tended toExpand

Aquatic Community Characteristics Influence the Foraging Patterns of Tree Swallows
During periods of inclement spring weather, Tree Swallows (Tachycineta bicolor) were observed foraging close to the surface of a series of experimentally manipulated ponds. Censuses of foragingExpand

NEST-BUILDING BEHAVIOR IN PCB-CONTAMINATED TREE SWALLOWS
Considerable attention has been directed toward documenting the effects of environmental chemicals on the endocrine systems of vertebrates, especially on development and reproduction. Given theExpand
