The distribution of the Iranian Culicinae is updated and reported by province. Larval habitat characteristics of each species, based on the information gathered throughout its range in Iran and at different times during the breeding season, are also presented.

Recent neutral landscape models derived from percolation theory predict that a landscape with sparse but contagious habitat coverage is functionally equivalent to one with more abundant but randomly situated habitat patches. We tested this prediction in a field experiment that determined how habitat-patch abundance and configuration affect landscape use by animals. Using a 2 x 2 factorial desig...

Some riparian areas of the country are in danger of deterioration due to uncontrolled exploitation coupled with loose implementation of environmental protection policies and regulations. Muleta River, a major watershed in Bukidnon, Philippines, was assessed to determine the present condition of its riparian habitat. Abiotic and biotic conditions of the river were assessed. Other factors includi...

– Habitat quality and landscape structure are key factors that determine the distributions of animals. The general characteristics of the habitat of Burrowing Owls (Athene cunicularia) have been well studied, but little is known about how landscape structure affects this species. Other studies have suggested that food resources for owls should be higher in small patches because of increased edg...

Arbuscular mycorrhizal fungi (AMF) play an essential role in complex ecosystems. However, the species diversity and composition of AMF communities remain unclear in semi-arid mountains. Further, it is not well understood if the characteristics of AMF community assemblies differ for different habitat types, e.g., agricultural arable land, artificial forest land, natural grassland, and bush/wood ...

The study of habitat use and selection in birds has a long tradition (Grinnell 1917, Kendeigh 1945, Svardson 1949, Hild6n 1965; Block and Brennan 1993). Early habitat-selection theory was characterized by correlative models of habitat characteristics and species abundance (MacArthur and Pianka 1966, Verner et al. 1986, Rosenzweig 1991), which subsequently evolved into models that involved densi...

Fish assemblages play a key role in stream ecosystems, and play a crucial role in the assessment of stream health. Physical habitat is a key component of stream ecosystems and plays a major role in determining biotic assemblages and stream integrity. There is increasing recognition of the role landscape factors play in determining biotic assemblages and stream integrity. Landscapes in Iowa and ...
