Large rivers and their riparian zones are hot spots of biodiversity (WARD et al. 1999). Fluvial geomorphic processes provide the habitat diversity and the specific habitat conditions for characteristic species assemblages and result in high levels of habitat diversity, local species richness (α-diversity), and between-habitat differences (beta-diversity) and consequently, overall species richne...

Habitat selection is the process by which individuals choose among available habitat patches. Habitat availability” as how accessible and procurable physical and biological components of a habitat are to animals. Research on small mammal habitat use helps to broaden their knowledge. Small mammals are often used as an indicator species group to reflect some aspects of “integrity. Small mammal ab...

We used abundance data and the program Focus to determine the spatial scale at which 31 species of longhorned beetles (Coleoptera: Cerambycidae) respond to forest habitat amount. We predicted that the spatial scale at which species respond would increase with body size, and that species using ephemeral larval habitat would respond at larger spatial scales than species using more stable larval h...

Asiatic Houbara ( Chlamydotis macqueenii ) is a flagship and vulnerable species. In-situ conservation of this threatened species demands for knowledge of its habitat selection. The aim of this study was to determine habitat variables influencing birds wintering and breeding selection in semiarid central Iran. Habitat features of the detected nest and pellet sites were compared with paired and r...

During natal dispersal, young animals leave their natal area and search for a new area to live. In species in which individuals inhabit different types of habitat, experience with a natal habitat may increase the probability that a disperser will select the same type of habitat post-dispersal (natal habitat preference induction or NHPI). Despite considerable interest in the ecological and the e...

We use a spatially explicit population model to explore the population consequences of different habitat selection mechanisms on landscapes with fractal variation in habitat quality. We consider dispersal strategies ranging from random walks to perfect habitat selectors for two species of arboreal marsupial, the greater glider (Petauroides volans) and the mountain brushtail possum (Trichosurus ...

assiganga stream is an important tributary of bhagirathi river in central himalaya (india). the stream is characterized by heterogeneity in habitat and substratum features harboring diverse fish fauna. at present this stream is facing threat of being fragmented by the construction of two hydro-electric projects. present study aimed to study fish diversity and their habitat use in assiganga stre...

Accurate and reliable identification of potential nesting habitat is required to manage for the threatened Marbled Murrelet (Brachyramphus marmoratus). Three habitat classifications are typically used by wildlife planners: a bivariate suitability algorithm following recommendations of the Canadian Marbled Murrelet Recovery Team (CMMRT) and based on geographical information systems (GIS), and tw...

Proxies are adopted to represent biodiversity patterns due to inadequate information for all taxa. Despite the wide use of proxies, their efficacy remains unclear. Previous analyses focused on overall species richness for fewer groups, affecting the generality and depth of inference. Biological taxa often exhibit very different habitat preferences. Habitat groupings may be an appropriate approa...

Jones, Biology Department, Appalachian State University, 572 Rivers Street, Boone, NC 28608-2027, USA e-mail: [email protected] Determining how to best measure habitat quality is essential for many conservation plans and basic ecological questions. Territory quality is thought to be a product of physical habitat characteristics (i.e., habitat quality) and the densit...
