چکیده

Species-area relationships (SPARs) dictate a people reduce the area available to wild species, they impose a linear reduction of the earth’s species diversity sea change in the strategies of biodiversity conservation. SPARs exist at three ecological scales: Sample-area SPARs that will follow the largest of these scales, i.e. each 1% reduction of natural area will cost about 1% of steady(a larger area within a biogeographical province will tend to include more habitat types, and thus more species, state diversity. Reserving small tracts of wild habitat can only delay these reductions. But we can stop most of them than a smaller one), Archipelagic SPARs (the islands of an archipelago show SPARs that combine the habitatby redesigning anthropogenic habitats so that their use is compatible with use by a broad array of other species. sampling process with the problem of dispersal to an island), and Interprovincial SPARs (other things being That is reconciliation ecology. Many pilot projects, whether intentionally or inadvertently espousing reconciliation equal, the speciation rates of larger biogeographical provinces are higher and their extinction rates are lower, ecology, are demonstrating that it can be done. leading to diversities in proportion to provincial area). SPARs are the products of steady-state dynamics in

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...

Loss of speciation rate will impoverish future diversity.

Human activities have greatly reduced the amount of the earth's area available to wild species. As the area they have left declines, so will their rates of speciation. This loss of speciation will occur for two reasons: species with larger geographical ranges speciate faster; and loss of area drives up extinction rates, thus reducing the number of species available for speciation. Theory predic...

Fire Ecology of Ground Vegetation in Pinus roxburghii Sargent Plantations in North-West Himalaya - Floristic Composition and Species Diversity

Effect of fire on phyto-sociology of understorey vegetation in chir pine forests of three different silvological characteristics was compared with pure grassland. 15 grasses, 1 sedge, 5 legumes and 21 non-legumes were recorded in the four study sites. Floristic composition gradually increased from June to August and then declined slowly by October in all the plots. Maximum number of species wa...

Temporal study of Solduz wetland microalgae in southern part of Lack Urmia

Phytoplankton is one of the main components of wetlands, which plays a vital role in providing nutrients, oxygen for other organisms, stabilizing nitrogen and carbon dioxide. In the meantime, the current status of Lake Urmia highlights the need to conserve and protect wetlands related to these ecosystems and their living and non-living components. Therefore, this study was conducted to assist i...
