Understanding distributions of wildlife species is a key step towards identifying biodiversity hotspots and designing effective conservation strategies. In this paper, the spatial pattern of diversity of birds in Golestan Province, Iran was estimated. Ecological niche modeling was used to determine distributions of 144 bird species across the province using a maximum entropy algorithm. Richness...

BACKGROUND: Campylobacteriosis is one of the most commonbacterial intestinal disorders of humans in many countries.A wide range of domestic and wild bird species have been identifiedas natural reservoirs. OBJECTIVES: The aim of this studywas to determine the Campylobacter spp from pet birds andscreen the determined Campylobacters for presence of virulencecytolethal distending toxin (cdt) genes....

Outbreaks of avian influenza in North American poultry have been linked to wild waterfowl. A first step towards understanding where and when avian influenza viruses might emerge from North American waterfowl is to identify environmental and demographic determinants of infection in their populations. Laboratory studies indicate water temperature as one determinant of environmental viral persiste...

Neotropical migratory birds are major components of the avifauna in most North American terrestrial ecosystems. Over 150 species of Neotropical migratory birds are known to breed in North America (Finch 199Ia). Given the large number of species, developing effective management strategies for Neotropical migratory birds is a monumental task because each species exploits a unique niche, and thus ...

Many migratory songbirds follow circuitous migratory routes instead of taking the shortest path between overwintering and breeding areas. Here, we study the migration patterns in Swainson's thrush (Catharus ustulatus), a neartic-neotropical migrant songbird, using molecular genetic approaches. This species is presently separated into genetically distinct coastal and continental populations that...

city parks play an important role in the welfare of metropolitan people. higher species richness of birds can be considered as a reflection of the health of the park and may satisfy visitors to a higher extent being in a more natural environment. we studied the influence of area and shape of city parks on bird species richness and diversity. 13 parks from among the 35 main city parks in isfahan...

Coastal wetlands, the major component of coastal ecotones with indispensable ecosystem services, are threatened by anthropogenic disturbance, resulting in continuous loss functions. wetland restoration can be implemented to deter losses; however, it is unclear whether could provide appropriate habitat for birds using on ecotones. Here, we utilize a newly restored as an example investigate impac...

An autoinoculative device was used to test the ability of sap beetles (Coleoptera: Nitidulidae) to carry a specific strain of Beauveria bassiana (Balsamo) Vuillemin to overwintering sites in a multiyear field study. The device was baited with the pheromone and coattractants for the dusky sap beetle (Carpophilus lugubris Murray) and placed in the field in the fall of each year. The introduced st...
