Density‐dependence by habitat heterogeneity: individual quality versus territory quality [PDF]

open access: yesOikos, 2008
The aim of this comment is to review the ecological issues concerning the role of individual and habitat heterogeneity as possible mechanisms explaining density‐dependent fecundity in animal populations. Our intention is to discuss different approaches to determine whether or not studied populations are subjected to density‐dependent processes and ...

Habitat-Specific Foraging of Prothonotary Warblers: Deducing Habitat Quality [PDF]

open access: yesThe Condor, 2005
Abstract Foraging behavior often reflects food availability in predictable ways. For example, in habitats where food availability is high, predators should attack prey more often and move more slowly than in habitats where food availability is low.

Measuring Habitat Quality: A Review [PDF]

open access: yesThe Condor, 2007
AbstractAbstract. Understanding habitat quality for birds is crucial for ecologists and managers, but few papers have explored the advantages and disadvantages of different ways to measure it. In this review I clarify terminology and distinguish habitat quality from related terms, differentiate habitat quality at the levels of individual birds and ...

Modelling fish habitat preference with a genetic algorithm-optimized Takagi-Sugeno model based on pairwise comparisons [PDF]

open access: yes, 2011
Species-environment relationships are used for evaluating the current status of target species and the potential impact of natural or anthropogenic changes of their habitat. Recent researches reported that the results are strongly affected by the quality
