Mechanistic Approaches to the Investigation of Edge Effects on Avian Productivity, to ecotones. In this chapter the term . refers generally to any such spatial gradients. (A glossary of terms and symbols is provided as an appendix. All terms included in the appendix were italicized on first mention in the text.) Edge effects may involve increases in avian breeding density near ed

In that season, shortened days, diminishing and perhaps unpredictable food supplies, and inclement weather all present special challenges for foraging and acquiring energy. Caching of food assists some species in meeting these challenges (Pravosudov

Wetlands Protection: The Forgotten Agendaration that has long intrigued biologists is the occurrence of differential migration, in which distance traveled differs between portions of a population.
