AN ASSESSMENT OF BIRD HABITAT QUALITY USING POPULATION GROWTH RATES

Habitat-Specific Population Growth of a Farmland Bird

BACKGROUND To assess population persistence of species living in heterogeneous landscapes, the effects of habitat on reproduction and survival have to be investigated. METHODOLOGY/PRINCIPAL FINDINGS We used a matrix population model to estimate habitat-specific population growth rates for a population of northern wheatears Oenanthe oenanthe breeding in farmland consisting of a mosaic of disti...

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Quantifying Bird-HaBitat using a relevé MetHod

The relevé method, a standardized, floristically based vegetation sampling technique developed in Europe, has become a vegetation measurement method used worldwide. Although the relevé method was developed by plant ecologists to classify vegetation, ornithologists have begun to use the method for bird-habitat studies, sometimes including modifications to better sample structural features of a h...

Expected Effects of Correlated Habitat Variables on Habitat Quality and Bird Distribution

Habitats are composed of multiple variables, each of which may affect one or more population demographic rates. The patterns of correlation among habitat variables can introduce correlations among demographic rates, even if any single habitat variable affects only a single demographic rate and is independent of others. I present a simple model in which habitat is composed of two continuous habi...
