Spatially explicit model of wintering common loons: conservation implications
Common loons Gavia immer are a conservation concern in New England due to a variety of anthropogenic factors, yet little is known about biotic and abiotic environmental factors determining their wintering distribution and abundance in nearshore and offshore waters. The primary objective of this study was to develop a spatially explicit abundance model of wintering common loons in the maritime w...
متن کاملPatterns of Mortality among Common Loons Wintering in the Northeastern Gulf of Mexico Laurence
-The mortality of Common Loons ( G ~ o i a i m n ~ e ~ ) wintering along the northeastern Gulf of Mexico from 1983 to 1988 exhibited several major patterns. First, there was a strong relationship between the timing of mortality and molt. Second, adults experienced higher mortality than sub-adults, but there was no difference in levels of mortality between sexes. Third, the homogeneity of mortal...
متن کاملSpatially Explicit Trends in the Global Conservation Status of Vertebrates
The world's governments have committed to preventing the extinction of threatened species and improving their conservation status by 2020. However, biodiversity is not evenly distributed across space, and neither are the drivers of its decline, and so different regions face very different challenges. Here, we quantify the contribution of regions and countries towards recent global trends in ver...
متن کاملSpatially Explicit Model of Deforestation in Bolivia
A GIS compiled by the Departmental Government of Santa Cruz, Bolivia offers data that may help to resolve some competing theories of tropical deforestation. The GIS contains many attributes relating to land use at two points in time, 1989 and 1994, and allow us to address questions like: • What has been the impact of past road construction on deforestation and land use? • What impacts might be ...
متن کاملConservation Ecology: In situ behavioral response of common loons associated with elevated mercury (Hg) exposure
Common Loons (Gavia immer) in Nova Scotia, Canada have the highest blood mercury (Hg) concentrations of any loon population in North America. Previous studies have shown that exposure to varying levels of Hg in prey is associated with changes in pre-nesting adult behavior. We report here the first association of sublethal blood Hg contamination with changes in behavior of Common Loon young. As ...
