Habitat loss and fragmentation affect forest birds through direct loss of breeding habitats,
detrimental edge effects such as increased nest predation and brood parasitism, and possibly …

The end-Ordovician was an enigmatic interval in the Phanerozoic, known for massive glaciation
potentially at elevated CO 2 levels, biogeochemical cycle disruptions recorded as large …

Objective— To compare synovial fluid characteristics of cattle with infectious and noninfectious
arthritis. Study Design— Retrospective cohort study. Animal or Sample Population— 130 …

Spatially-explicit, individual-based models are increasingly used to evaluate the effects of
habitat loss and fragmentation on habitat use and population persistence. Yet, they are …

Logging is considered the most important threat to species in boreal forests. In contrast to
eastern Canada, where most boreal forests remain largely untouched, in Fennoscandia it is …

Despite intensive recent research on the effects of habitat loss and fragmentation on bird
populations, our understanding of underlying demographic causes of population declines is …

Widespread marine anoxia is hypothesized as the trigger for the second pulse of the Late
Ordovician (Hirnantian) mass extinction based on lithologic and geochemical proxies that …

The end Ordovician was a critical period in Earth history. It was a time of global climatic
change with large-scale continental glaciations. A wealth of recent work has documented the …

Forest fragmentation and habitat loss may disrupt the movement or dispersal of forest–dwelling
birds. Despite much interest in the severity of these effects and ways of mitigating them, …

Geochemical redox proxies indicate that seafloor anoxia occurred during the latest Ordovician
glacial maximum, coincident with the second pulse of the Late Ordovician mass extinction…
