Upland Nesting Prairie Shorebirds: Use of Managed Wetland Basins and Accuracy of Breeding Surveys

Avian Conservation and Ecology, 2006
Wetlands in southern Alberta are often managed to benefit waterfowl and cattle production. Effects on other species usually are not examined. I determined the effect of managed wetlands on upland-nesting shorebirds in southern Alberta by comparing ...

Isotopic ordering in eggshells reflects body temperatures and suggests differing thermophysiology in two Cretaceous dinosaurs [PDF]

, 2015
Our understanding of the evolutionary transitions leading to the modern endothermic state of birds and mammals is incomplete, partly because tools available to study the thermophysiology of extinct vertebrates are limited.

The Biogeography of Marbled Godwit (Limosa fedoa) Populations in North America [PDF]

, 2011
We equipped 28 Marbled Godwit from four locations in North America with miniature satellite transmitters to determine migration routes, strategy, and connectivity. Godwits captured in Utah (n = 13) went to breeding sites in Alberta, Saskatchewan, Montana and North Dakota and wintered along the Baja Peninsula and west coast of mainland Mexico. They used

Comparative tests of ectoparasite species richness in seabirds [PDF]

, 2007
Background: The diversity of parasites attacking a host varies substantially among different host species. Understanding the factors that explain these patterns of parasite diversity is critical to identifying the ecological principles underlying ...

Sex differences in migration routes and non-breeding areas of a declining shorebird

Avian Conservation and Ecology
Migratory birds face different threats and pressures across their annual cycle, and understanding the impact of these factors on individuals is critical to the conservation of avian populations. Individuals from the same breeding population may share the

Spatiotemporal scaling of North American continental interior wetlands: implications for shorebird conservation [PDF]

, 2012
Within interior North America, erratic weather patterns and heterogeneous wetland complexes cause wide spatio-temporal variation in the resources available to migrating shorebirds.
