pollination and pest control are perhaps the best-known ecological services performed by hover flies. the species diversity and their abundance have an influential impact on the ecological services provided by this family. to find out species diversity of adult flower flies associated with agroecosystems in kerman province, a biodiversity survey using insect net and color water traps was conduc...

There are widespread concerns that anthropogenic climate change will become a major cause of global biodiversity loss. However, the potential impact of climate change on the extinction risk of species remains poorly understood, particularly in comparison to other current threats. The objective of this research was to examine the relative impact of climate change on extinction risk of upper mont...

This paper provides an overview of efforts to create an informatics infrastructure for the biodiversity community. A vast amount of biodiversity information exists, but no comprehensive infrastructure is in place to provide easy assess and effective use of this information. The advent of modern information technologies provides a foundation for a remedy. Biodiversity informatics infrastructures...

Biologists seek an understanding of the biological and environmental factors determining local community diversity. Recent advances in metacommunity ecology, and neutral theory in particular, highlight the importance of dispersal processes interacting with the spatial structure of a landscape for generating spatial patterns and maintaining biodiversity. The relative spatial isolation of a commu...

Monitoring and research activities may hinder rather than improve conservation in tropical countries. Those concerned with conservation—particularly academics and aid agencies—too often overlook the practical realities of achieving conservation in the tropics. As a result, many initiatives divert scarce resources away from fundamental management priorities. I identify some critical threats to b...

in this study, species richness, evenness and vegetation biodiversity were investigated in stabilized and non-stabilized cut edge areas of chachkam district forest roads in sari forest of iran. 18 micro plots 1×1m (36 micro plots) were sampled to carry out this research on two cut edge areas. number of trees, shrubs and herbaceous were recorded in each micro-plot. significant difference was inv...

the purpose of this study was to investigate the distribution and biodiversity of diatoms during different seasons and their correlation with water quality parameters in helleh river estuary, bushehr, persian gulf. samples were taken in mid-season from summer 2011 to spring 2012 during a one-year period from different stations. results showed that diatoms mostly comprised of bacillariophyceae, ...

Researchers working with biodiversity try to understand organisms adaptation in their environmental niche and try to provide subsidies for conscious use of natural resources by scientific organizations and government institutions. This work aims to support the cooperation among the researchers of a species distribution modeling network. The cooperation is based on sharing modeling results, whic...
