Bird metacommunities in temperate South American forest: vegetation structure, area, and climate effects.
Spatial structure in metacommunities and their relationships to environmental gradients have been linked to opposing theories of community assembly. In particular, while the species sorting hypothesis predicts strong environmental influences, the neutral theory, the mass effect, and the patch dynamics frameworks all predict differing degrees of spatial structure resulting from dispersal and com...
متن کاملClimate change and bird reproduction: warmer springs benefit breeding success in boreal forest grouse
Global warming is predicted to adversely affect the reproduction of birds, especially in northern latitudes. A recent study in Finland inferred that declining populations of black grouse, Tetrao tetrix, could be attributed to advancement of the time of mating and chicks hatching too early-supporting the mismatch hypothesis. Here, we examine the breeding success of sympatric capercaillie, T. uro...
متن کاملUnderstanding testosterone variation in a tropical lek-breeding bird.
Male reproductive coalitions, in which males cooperate to attract females, are a rare strategy among vertebrates. While some studies have investigated ultimate aspects of these relationships, little is known about the mechanistic role that hormones play in modulating cooperative behaviours. Here, we examined male testosterone variation in a tropical lekking bird, the wire-tailed manakin (Pipra ...
متن کاملMore from the Primeval Forest
two octavo volumes; as this has been translated into English, we gather that it is a book of some consequence. Yet, he has dragged himself away from all his interests in Europe and devoted a valuable part of his life to medical missionary work in equatorial Africa. Such a man must be either a restless crank or a true altruist, and, as it is obvious from his writings that Dr. Schweitzer is not t...
متن کاملBreeding, Early-Successional Bird Response to Forest Harvests for Bioenergy
Forest regeneration following timber harvest is a principal source of habitat for early-successional birds and characterized by influxes of early-successional vegetation and residual downed woody material. Early-successional birds may use harvest residues for communication, cover, foraging, and nesting. Yet, increased market viability of woody biomass as bioenergy feedstock may intensify harves...
