Both climatic and edaphic conditions determine plant distribution, however many species distribution models do not include edaphic variables especially over large geographical extent. Using an exceptional database of vegetation plots (n = 4839) covering an extent of ∼55,000 km2, we tested whether the inclusion of fine scale edaphic variables would improve model predictions of plant distribution...

soil-dwelling mites and especially gamasina (mesostigmata) are very important to soil ecosystems. they are one of the major groups rich in species and abundance. in order to study mesostigmatic mite fauna, soil samples were collected from different oak forests of lordegan region. the mites were extracted using berlese-tullgren funnels and then cleared in lactic acid and mounted in hoyer's mediu...

Abstract In the literature, 114 species of arthropods associated to Microtus oeconomus have been reported in entire area their occurrence. There are eight hard ticks, 52 gamasid and chigger mites, 47 fleas seven sucking lice. general, dominant parasites Palearctic Nearctic root vole populations either western or species. The analysis geographical range occurrence indicates that most them occur ...

Ecological niche modeling (ENM) is a broadly used tool in different fields of plant ecology. Despite the importance of edaphic conditions in determining the niche of terrestrial plant species, edaphic data have rarely been included in ENMs of plant species perhaps because such data are not available for many regions. Recently, edaphic data has been made available at a global scale allowing its ...

Lasthenia californica sensu Ornduff consists of two races that differ in their flavonoid pigments and edaphic tolerances. Recent phylogenetic studies of Lasthenia have revealed that members of L. californica sensu Ornduff belong to two phylogenetic species. The relationship of the edaphic races to these new species and to each other is the focus of this study. Characterization of flavonoid prof...

Both genetic drift and divergent selection are expected to be strong evolutionary forces driving population differentiation on edaphic habitat islands. However, the relative contribution of genetic drift and divergent selection to population divergence has rarely been tested simultaneously. In this study, restriction-site associated DNA-based population genomic analyses were applied to assess t...
