AIM Geographic, climatic, and soil factors are major drivers of plant beta diversity, but their importance for dryland plant communities is poorly known. This study aims to: i) characterize patterns of beta diversity in global drylands, ii) detect common environmental drivers of beta diversity, and iii) test for thresholds in environmental conditions driving potential shifts in plant species co...
Abstract Arid climates are characterized by a summer drought period to which animals seem adapted. However, in some years, the can extend for unusually longer periods. Examining effects of these current extreme weather events on biodiversity help understand climate change, as models predict an increase severity. Here, we examined “unusual” extended soil invertebrate prey availability and diet c...
Arbuscular Mycorrhizal Fungi (AMF) play major roles in ecosystem functioning such as carbon sequestration, nutrient cycling, and plant growth promotion. It is important to know how this ecologically important soil microbial player is affected by soil abiotic factors particularly heavy metal and metalloid (HMM). The objective of this study was to understand the impact of soil HMM concentration o...
butterflies of the inani reserve forest were studied between may 2014 and may 2015. one hundred twenty five species of butterflies belonging to 84 genera and six families (hesperiidae, papilionidae, pieridae, lycaenidae, riodinidae and nymphalidae) were recorded during this study. the highest number of species comprised family nymphalidae (38 species, 30.4%) followed by lycaenidae (35 species, ...
Soil is a fundamental component of the biosphere, whose properties and quality are affected by human activities, such as agriculture. health for different ecosystem services soil biota has crucial role in maintaining it. Elucidating how crops agricultural practices affect invertebrates communities relevance. In present study, DNA metabarcoding approach was adopted to evaluate effects biotic abi...
Nitrogen deposition has dramatically altered biodiversity and ecosystem functioning on the earth; however, its effects on soil bacterial community and the underlying mechanisms of these effects have not been thoroughly examined. Changes in ecosystems caused by nitrogen deposition have traditionally been attributed to increased nitrogen content. In fact, nitrogen deposition not only leads to inc...
The Oman Sea (Makoran) has always been influenced by the monsoon currents, and this phenomenon is a natural stressor for species inhabiting the marine ecosystem, including bivalve molluscs. To study the diversity of subterranean bivalves sampled from three areas of Ramin, Beris, and Pasabandar, a total of 10 stations, in the winter of Pre-Manson, Mansoon and Post Mansoon in 2018. In this study,...
Multitrophic communities that maintain the functionality of the extreme Antarctic terrestrial ecosystems, while the simplest of any natural community, are still challenging our knowledge about the limits to life on earth. In this study, we describe and interpret the linkage between the diversity of different trophic level communities to the geological morphology and soil geochemistry in the rem...
Numerical indices of diversity, in their entirety, do not provide a complete description of distribution and richness of species. Therefore, parametric indices should be also considered in studying of plant communities. In this regard, the indices of species richness, evenness and diversity related to the ecological sites of Cher mountainous rangelands of Urmia were calculated. The diversity pr...
Livestock grazing is a common human-induced activity with direct and indirect effects even on the ecosystems of protected areas. The present study analyzed the effects of different grazing management methods on species diversity and richness in the steppe rangelands of Saveh, Iran. Data were collected from sixty 2×2 m plots within the areas of three, four-years protected range management projec...
