Extraterritorial movements of a forest songbird in a fragmented landscape

Article Abstract:

A novel approach to study avian movements in a fragmented landscape is presented. Results suggest that the ability to travel between forest patches in fragment landscapes is important in maintaining avian diversity in the temperature zone, particularly because Neotropical migrants have high rates of extra-pair copulations.

Songbird abundance and avian nest survival rates in forests fragmented by different silvicultural treatments

Article Abstract:

Two-age timber management has conservation benefits for wildlife that provides greater habitat complexity, nest sites and food sources. It was observed that at the species level few differences existed in songbird nest success among treatments and that nest success did not differ with distance from the edge of the cut.

When Good Animals Love Bad Habitats: Ecological Traps and the Conservation of Animal Populations

Article Abstract:

The ecological trap concept suggests that the existence of a trap within a given landscape will, under most situations, drive a local animal population to extinction. Methods for identifying traps and predicting their impact on populations are presented.
