Heterobasidion spp. pathogenic fungi produce conspicuous fruitbodies on infected wood, which may represent a habitat for range of organisms, including invertebrates. The aim was to: (i) assess and compare invertebrate diversity in fruitbodies, Picea abies wood adjacent soil; (ii) test methods collecting invertebrates from fruitbodies. A total 69 fruitbody samples, 46 samples 19 soil were collec...
Earthworms are known to modify life conditions for other soil organisms through their drilospheric activities. The effects of a large anecic species, Martiodrilus carimaguensis JimeÂnez and Moreno, on soil macrofaunal communities were investigated in a natural and a man-made grassland of the Eastern Plains of Colombia. Invertebrates were sampled by a standard hand sorting method at different sp...
Soil bacteria and fungi play key roles in the functioning of terrestrial ecosystems, yet our understanding of their responses to climate change lags significantly behind that of other organisms. This gap in our understanding is particularly true for drylands, which occupy ∼41% of Earth´s surface, because no global, systematic assessments of the joint diversity of soil bacteria and fungi have be...
Mites are the best representative of soil arthropods because they are the most diverse in terms of ecological niche and behavior. In this study, abundance and biodiversity of laelapid soil mites were evaluated in eight sites in Saman and Shahrekord, with each site including an orchard and a farmland. There was a significant difference in the Shannon-Wiener diversity index of laelapid mites amon...
the morphological diversity of arbuscular mycorrhizal fungi (amf) at the anguran zn and pb mining region (zanjan province, iran) were studied along a transect from the mine to 4500 m away. within each plot, a composite sample of root and rhizospheric soil from a dominant indigenous plant was collected. the soil samples were analyzed for their physico-chemical characteristics. spores were extrac...
In high-latitude ecosystems climate change induced plant community shifts towards dominance of shrubs and trees will potentially have large consequences for soil carbon dynamics. Changes in the litter layer due to an altered quantity and quality of litter input, or by its indirect effect on microclimatic conditions, might affect the decomposer community. To be able to predict the effects of inc...
Present study investigates macrobenthic invertebrates and their community structure in Chafrood river to classify and assess the study sites regarding the environmental anthropogenic factors. Along a 9 km distance, 8 study sites were selected, and macrobenthic were monthly sampled using a surber sampler (1600cm2, 250 μ mesh net) with 3 replicate at each station. Collected samples organisms were...
Climate models predict significant future warming in polar regions. In the McMurdo Dry Valleys, Antarctica, projected summer climate warming is expected to increase snow and glacial melt, resulting in higher stream discharge, rising lake levels, and an increase in areas of moist soil, but the potential influence of warming and associated changes in hydrology on the soil ecosystem is poorly unde...
Grazing lands and rangelands are increasingly recognized as an important alternative to other developed land uses for sustaining ecological communities in Florida, the rest of the southeastern United States, and other regions. It is important to understand factors that in uence ecological communities on private grazing lands, especially in areas with abundant wetlands, which are often sensitiv...
