Species abundance in a forest community in South China: A case of poisson lognormal distribution Species abundance in a forest community in South China: A case of poisson lognormal distribution
Case studies on Poisson lognormal distribution of species abundance have been rare, especially in forest communities. We propose a numerical method to fit the Poisson lognormal to the species abundance data at an evergreen mixed forest in the Dinghushan Biosphere Reserve, South China. Plants in the tree, shrub and herb layers in 25 quadrats of 20 m??20 m, 5 m??5 m, and 1 m??1 m were...

Does choice of estimators influence conclusions from true metabolizable energy feeding trials? Does choice of estimators influence conclusions from true metabolizable energy feeding trials?
True metabolizable energy (TME) is a measure of avian dietary quality that accounts for metabolic fecal and endogenous urinary energy losses (EL) of non-dietary origin. The TME is calculated using a bird fed the test diet and an estimate of EL derived from another bird (Paired Bird Correction), the same bird (Self Correction), or several other birds (Group Mean Correction). We evaluated...

Markov Chain Monte Carlo estimation of species distributions: A case study of the swift fox in western Kansas Markov Chain Monte Carlo estimation of species distributions: A case study of the swift fox in western Kansas
Accurate maps of species distributions are essential tools for wildlife research and conservation. Unfortunately, biologists often are forced to rely on maps derived from observed occurrences recorded opportunistically during observation periods of variable length. Spurious inferences are likely to result because such maps are profoundly affected by the duration and intensity of...

Landscape composition, patch size, and distance to edges: Interactions affecting duck reproductive success Landscape composition, patch size, and distance to edges: Interactions affecting duck reproductive success
Prairies and other North American grasslands, although highly fragmented, provide breeding habitat for a diverse array of species, including species of tremendous economic and ecological importance. Conservation and management of these species requires some understanding of how reproductive success is affected by edge effects, patch size, and characteristics of the landscape. We examined...

Population genetic structure in migratory sandhill cranes and the role of Pleistocene glaciations Population genetic structure in migratory sandhill cranes and the role of Pleistocene glaciations
Previous studies of migratory sandhill cranes (Grus canadensis) have made significant progress explaining evolution of this group at the species scale, but have been unsuccessful in explaining the geographically partitioned variation in morphology seen on the population scale. The objectives of this study were to assess the population structure and gene flow patterns among migratory...

Habitat and nesting of Le Conte's Sparrows in the northern tallgrass prairie Habitat and nesting of Le Conte's Sparrows in the northern tallgrass prairie
Little is known about the breeding biology of the Le Conte's Sparrow (Ammodramus leconteii), probably because of its secretive nature. We provide new information on several aspects of Le Conte's Sparrow breeding biology, including rates of nest parasitism by Brown-headed Cowbirds (Molothrus ater) and potential factors affecting breeding densities and nesting success of the species. Our...
