Study on relationships between a species with its surrounding biotic and abiotic environment provides valuable information in terms of optimum choice for utilization, propagation, breeding and domestication. In other words, ecological study of behavior as essential elements of their ecosystems and habitat characteristics in order to find appropriate solutions to maintain, revise and revitalize ...

All naturalists know that the world is heterogeneous in space and time, for almost any physical property and at almost any scale one cares to examine. The diversity of life—the number of species that exist, and how they are organized into complex communities—must reflect in some way the magnitude and structure of that hetereogeneity. Ecologists use random quadrats to sample the world. The insig...

The establishment of linkages between habitats is of great importance to avert the detrimental impacts of land fragmentation and climate change on biodiversity. Linkages need to be cost-efficient, and should account for specific dispersal requirements of species. Since cost-efficient linkages defined independently for each individual species are more costly than linkages optimised for multiple ...

   Background and aims: Mosquitoes (Diptera: Culicidae) are still a focus of research because of their role in the transmission of diseases and annoying biting behavior. Source reduction is an effective measure to control mosquito populations, which is based on good knowledge of larval habitats. This study was conducted to obtain that basic knowledge in Chaharmahal and Bakhtiari province....

Megalopae of several crab species exhibit active habitat selection when settling. These megalopae usually select structurally complex habitats which can provide refuge and food. The portunid mud crab, Scylla serrata, is commonly found within the muddy estuaries of the Indo-West Pacific after attaining a carapace width > 40 mm. Despite substantial efforts, the recruitment mechanism of juvenile m...

Decision makers and the general public show an increasing interest in understanding the criterion for conserving and protecting endangered habitats under the EU habitats directive. Often a well structured visualization may be more convincing than a thick report explaining the same facts. The distribution and abundance of rare plant and animal communities influence the spatial arrangement of end...

Animal species are seldom distributed evenly at either local or larger spatial scales, and instead tend to aggregate in sites that meet their resource requirements and maximise fitness. This tendency is likely to be especially marked in arid regions where species could be expected to concentrate at resource-rich oases. In this study, we first test the hypothesis that productive riparian sites i...

Anthropogenic alterations of woodland habitat may influence stopover biology, which in turn could alter the stress physiology of migratory landbirds. Woodland stopover habitats are scarce in the Northern Prairie region of North America and consist of native riparian corridor woodlands (corridors) and smaller, more isolated woodlots of anthropogenic origin around farmsteads (woodlots). Corridor ...
