Effects of Alpine land‐use changes: Soil macrofauna community revisited
Although soil invertebrates play a decisive role in maintaining ecosystem functioning, little is known about their structural composition in Alpine soils and how their abundances are affected by the currently ongoing land-use changes. In this study, we re-assessed the soil macrofauna community structure of managed and abandoned Alpine pastureland, which has already been evaluated 14 years earli...
متن کاملImpact of Land Use Changes on some Soil Micromorphological Features in Rakat Watershed, Eastern Khuzestan Province
The objective of this study was to investigate the impact of land use change (forest and rangelands to agriculture) on some micromorphological indices of soil quality in part of Rakat watershed, southwest of Iran. Accordingly, intact soil samples from 0-15 and 15-30 cm depths were collected from the above-mentioned land uses, and microstructure, type and abundance of voids, redoximorphic featur...
متن کاملLand use change alters functional gene diversity, composition and abundance in Amazon forest soil microbial communities.
Land use change in the Amazon rainforest alters the taxonomic structure of soil microbial communities, but whether it alters their functional gene composition is unknown. We used the highly parallel microarray technology GeoChip 4.0, which contains 83,992 probes specific for genes linked nutrient cycling and other processes, to evaluate how the diversity, abundance and similarity of the targete...
متن کاملphylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
The Local Articulation of Policy Conflict: Land Use, Environment, and Amerindian Rights in Eastern Amazonia*
The Brazilian government has promoted development in Amazonia for over forty years. Nevertheless, improvement of rural conditions has been limited. Although tropical deforestation has been the premier concern in discussions about Amazonia, this article focuses instead on the human dimensions of development and the apparent failings of social policy in the region. In so doing, the article argues...
