Projected mercury dietary exposure of three bird species nesting on a contaminated floodplain (South River, VA, USA)
Dietary mercury exposure was modeled for Carolina wren (Thryothorus ludovicianus), Eastern song sparrow (Melospiza melodia) and Eastern screech owl (Otus asio) nesting on the contaminated South River floodplain (Virginia, USA). Parameterization of Monte Carlo models required formal expert elicitation to define bird body weight and feeding ecology characteristics because specific information was ...

A study describes the migratory divide towards the pacific ocean and the Arabian sea in red-neck phalarope populations
When winter comes, populations of red-neck phalarope from the Western Palearctic migrate to two different destinations –the Pacific Ocean or the Arabian Sea- following an exceptional migratory divide strategy which has never been described in this geographical area. When winter comes, populations of red-neck phalarope from the Western Palearctic migrate to two different destinations ...

Influence of Targets and Assessment Region Size on Perceived Conservation Priorities
We used an existing conservation opportunity area (OA) data layer for four contiguous ecological subsections within the Ozark Highlands to quantitatively evaluate the influence of conservation targets and assessment region size on conservation priorities. OAs are natural and seminatural land-cover patches that are away from roads and away from patch edges. To evaluate the influence of targets, we ...

Temporal trends of perfluoroalkyl substances (PFAS) in eggs of coastal and offshore birds: Increasing PFAS levels associated with offshore bird species breeding on the Pacific coast of Canada and wintering near Asia
Perfluoroalkyl substances (PFAS) such as perfluoroalkyl carboxylates (PFCAs) and perfluoroalkyl sulfonates (PFSAs) have become virtually ubiquitous throughout the environment, and, based on laboratory studies, have known toxicological consequences. Various national and international voluntary phase‐outs and restrictions on these compounds have been implemented over the last 10 to 15 years. In ...

Distribution of neotropical migratory bird species across an urbanizing landscape
Urbanization leads to long-term modification of landscapes by habitat loss, fragmentation, and the creation of new habitats. Species’ distributions respond to these modifications of habitat availability, but the combination of parameters and scale at which habitat alteration most strongly influences species distributions is poorly understood. We evaluated responses of neotropical migratory birds, ...

Earth out of sync rising temperatures throwing off seasonal timing
A newly hatched chick waits with hungry mouth agape for a parent to deliver its first meal. A crocus peaks up through the snow. Rivers flow swiftly as ice breaks up and snows melt. Sleepy mammals emerge from hibernation, and early frog songs penetrate the night. Spring awakening has long provided fodder for poets, artists, and almanac writers. Even for a notoriously fickle time of sunshine, ...
