Several dams have been built in central and north Argentina. There are more than 20 reservoirs in Córdoba province, with a total estimated surface area of around 15,000 ha. Although construction of dams continues, some aspects about the richness, abundance and diversity of ichthyofauna in many of these environments are unknown, which prevents adequate management of fish resources. The goal of t...

This paper presents the spatial and temporal variation in diversity of malacofauna relation to water chemistry Aripal stream Kashmir Himalaya. A total 12 species were reported which belong four families, Lymnaeidae, Physidae, Planorbidae, Bithyniidae from class Gastropoda, two Cyrenidae Pisidiidae Bivalvia. The family Planorbidae contributed 34% annual molluscan population followed by Lymnaeida...

Despite the ecological significance, social and economic values roles being played by pangolin, their remain under-studied in context to Nigeria. There is dearth of information on current status, distribution, habitat preferred pangolin especially tropical rainforest ecoregion Information overall ecology, preference distribution pattern study areas were generated. Species name, height diameter ...

AIMS Considered as an essential measure in the application of soil seed bank (SSB) projects, the mixing of substrate and surface soil can effectively improve soil condition. This research is aimed at exploring the diversity characteristics of SSBs and the relationships between SSBs and soil properties. METHODS Canonical correspondence analysis (CCA) was adopted to describe the ordination of S...

The tree layer vegetation of two protected ecosystems i.e. Similipal Biosphere Reserve (SBR) and Bhitarkanika National Park (BNP) of eastern ghat was analysed for structure, composition and diversity. With respect to the tree species composition the two protected ecosystems were differed from each other at the family, genera and species level. About 117 tree species representing 85 genera and 4...

Abstract The floristic composition, diversity, and conservation status of woody plant species in Ethiopia are determined this study. Data on vegetation collected using a systematic random sampling method from 45 20 m × (400m 2 ) plots laid every 100 along four parallel transect lines running south to north. Flora Eritrea identification key (Volume I–VIII) is used identify the scientific names a...

The quinoa (Chenopodium quinoaWilld.) crop is originated from Andean region (South America). Its nutritional values as well its drought climate and water salinity tolerant character have motivated many countries such Algeria to adapt a plant culture. This study aims assess entomofauna Hymenoptera order in terms of composition functional diversity. We aim also evaluate the consequences expansion...

The relationship between biodiversity and ecosystem functioning is a central issue in ecology, but how this relationship is affected by nutrient stress is still unknown. In this study, we analyzed the phytoplankton diversity effects on community biomass and stability along nutrient gradients in an artificial eutrophic lake. Four nutrient gradients, varying from slightly eutrophic to highly eutr...

The relationship between the diversity of mixed-species microbial consortia and their electrogenic potential in the anodes of microbial fuel cells was examined using different diversity measures as predictors. Identical microbial fuel cells were sampled at multiple time-points. Biofilm and suspension communities were analysed by denaturing gradient gel electrophoresis to calculate the number an...
