an investigation was carried out during april to december 2000 to study mosquito fauna and ecology in guilan prov ince of northern iran. the mosquito larvae were collected by dipping method and larval habitat characteristics recorded ac cording to hydro-ecological features. in total, 3937 larvae of the genus culex from 92 larval breeding sites were collected. six spe cies of the genus culex; cx...

background: ecological data are important in the vector control management of mosquitoes. there is scattered pub­lished information about the larval habitat characteristics and ecology of the genus anopheles (diptera: culicidae) in iran and most of available data is in relation to malaria vectors in southern iran. methods: this cross sectional investigation was carried out to study the mosquito...

There is a clear bias in the literature on island ecology towards terrestrial rather than marine systems, which have remained comparatively poorly studied. Marine populations are typically open, and local production may have little impact on local recruitment, such that long-distance dispersal is an important determinant of population ecology. Since oceanic islands form discrete patches of habi...

Global changes are shaping the ecology and biogeography of marine species and their fisheries. Macroecology theory, which deals with large scale relationships between ecology and biogeography, can be used to develop models to predict the effects of global changes on marine species that in turn affect their fisheries. First, based on theories linking trophic energetics and allometric scaling of ...

A species’ range limits may shift in space either because of changes in ecological factors (e.g. climate, the abundances of interacting species) or because the traits which influence range limits (e.g. dispersal, niche characteristics) evolve by natural selection. In Geographical Ecology, Robert MacArthur (1972) provided a synthesis of the evolutionary factors that may drive range dynamics. In ...

despite its largest range of distribution in comparison to other large carnivores in iran, the grey wolf has been the least-studied carnivore in the country with limited available data on its ecology. its social life and population composition have been investigated across its global range in europe and north america; however, it has been less explored in arid environments of asia. accordingly,...

ecological destruction in human-dominated landscapes has significant impacts on environment sustainability internationally. landscape planning can play a role in mitigating the effects of human-related activities. one element of landscape planning involves the analysis of the biological, spatial and social arrangement of areas in an urban environment and identifying characteristics that are und...
