Composition, Seasonal Occurrences and Habitat Use of Bird Assemblages in Wet Forests on the Central Plateau of Tasmania

تأثیر اندازه و شکل لکه‌های درخت‌زار ‌بر غنا و تنوع گونه‌ای پرندگان در منطقه حفاظت شده کرکس

  Determining landscape parameters influencing species richness of habitat patches is one of the most important issues in conservation biology. Many previous studies have investigated the influence of habitat parameters on bird assemblages in forest patches, but studies seeking effects of oasis parameters on bird assemblages are very scarce. Karkas Protected Area is located in semi-arid zone in...

The effects of habitat fragmentation on bird communities in Hyrcanian forests (Case study: Gorgan Township)

Seasonal and spatial variation in water availability drive habitat associations in a tropical forest.

Associations with topographic units or soil types that vary in water availability are widespread in plant communities and are one of the main structuring aspects for local species distribution patterns, yet the underlying mechanisms are poorly understood. We hypothesized that differential seedling performance across habitats, particularly during the dry season, leads to habitat associations in ...

Understorey bird responses to the edge-interior gradient in an isolated tropical rainforest of Malaysia

Forest fragmentation results in a loss of forest interior and an increase in edge habitat. We studied how understorey bird community composition and habitat variables changed along an edge-to-interior gradient in a 1248-ha lowland rainforest patch in peninsular Malaysia. Birds and environmental variables such as vegetation structure and litter depth were detected within a 25-m radius of each of...

Fish assemblages and habitat ecology of River Pinder in central Himalaya, India

Snow-fed River Pinder -a tributary of River Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...
