Urbanization, environmental stabilization and temporal persistence of bird species: A view from Latin America [PDF]
Background. A scarcely studied consequence of urbanization is the effect of temporal stabilization of the environment on bird communities. This alteration is thought to dampen environmental variations between day and night, seasons and years, promoting a

Ecological connection between fish preference in the diet of Siberian cranes and their incubation period in tundra zone [PDF]
We researched the ecology of the third rarest crane species, Siberian crane, which breeds in northern-eastern Siberian tundra. Nesting in places near great lakes, this crane appears to be an indicator of the global warming processes that affect lake ...

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Secondary reproductive strategies in Pacific black brant (Branta bernicla nigricans) [PDF]
Thesis (M.S.) University of Alaska Fairbanks, 1999Waterfowl are known to use secondary reproductive strategies, both extra-pair copulations and intraspecific brood parasitism, to increase fitness. We used five polymorphic microsatellite loci to determine

We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.
