Use of the superpopulation approach to estimate breeding population size: an example in asynchronously breeding birds.
Many populations of animals are fluid in both space and time, making estimation of numbers difficult. Much attention has been devoted to estimation of bias in detection of animals that are present at the time of survey. However, an equally important problem is estimation of population size when all animals are not present on all survey occasions. Here, we showcase use of the superpopulation app...
متن کاملSpatial heterogeneity in distribution and ecology of Western Palearctic birds.
Species vary in abundance and heterogeneity of spatial distribution, and the ecological and evolutionary consequences of such variability are poorly known. Evolutionary adaptation to heterogeneously distributed resources may arise from local adaptation with individuals of such locally adapted populations rarely dispersing long distances and hence having small populations and small overall range...
متن کاملThe prediction of Persian Squirrel Distribution Using a Combined Modeling Approach in the Forest Landscapes of Luristan Province
Habitat destruction is the most important factor determining species extinction; hence, the management of wildlife populations necessitates the management of habitats. Habitat suitability modeling is one of the best tools used for habitat management. There are several methods for habitat suitability modeling, with each of having some different advantages and disadvantages. In this study, we us...
متن کاملIndependent Effects of Forest Cover and Fragmentation on the Distribution of Forest Breeding Birds
The aims o f this study were ( 1 ) to determine the relative importance o f the independent effects o f forest cover and fragmentation on the distribution o f forest breeding birds, and ( 2 ) to test the hypothesis that the negative ef fect o f forest fragmentation on species distribution increases with decreasing forest cover, i.e., the negative interaction ef fect o f forest cover and fragmen...
متن کاملWhich Species Are We Researching and Why? A Case Study of the Ecology of British Breeding Birds
Our ecological knowledge base is extensive, but the motivations for research are many and varied, leading to unequal species representation and coverage. As this evidence is used to support a wide range of conservation, management and policy actions, it is important that gaps and biases are identified and understood. In this paper we detail a method for quantifying research effort and impact at...
