Background: Some members of family Calliphoridae are myiasis agents and mechanical vectors of some pathogens. The aim of this study was to measure the biodiversity and synanthropy behaviour of Calliphoridae flies in Abadan, Khuzestan province. Methods:Data were collected based on a monthly schedule during March to December 2014 in urban, semi-urban and rural e...

Reservoirs are significant sources of greenhouse gases (GHG), such as carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), to the atmosphere. These systems receive metabolize a larger amount organic inorganic nitrogen from their watersheds than lakes, resulting in production CO2, CH4 N2O. Despite global relevance, there still important uncertainties regarding magnitude, variability driv...

Including or excluding rare taxa in bioassessment is a controversial topic, which essentially affects the reliability and accuracy of the result. In the present paper, we hypothesize that biological indices such as Shannon-Wiener index, Simpson's index, Margalef index, evenness, BMWP (biological monitoring working party), and ASPT (Average Score Per Taxon) respond differently to rare taxa exclu...

Studies on echinoderms along the Panamanian Pacific coast have focused mainly on evolutionary and molecular analyses, however little ecological research has been done and mainly only on 2 species: Diadema mexicanum and Acanthaster planci. Herein, we describe for the first time the diversity (based on Margalef, Shannon and Pielou indices), distribution and density of echinoderms for some islands...

This study investigated the biodiversity, phylogeny, and antifungal activity of endophytic fungi isolated from Zanthoxylum bungeanum. A total of 940 isolates obtained were grouped into 93 morphotypes, 43 species, and 23 genera, which were authenticated by molecular identification based on rDNA internal transcribed spacer (ITS) sequence analysis. A high diversity of endophytic fungi from Z. bung...

We give a complete description of degenerations $3$-dimensional nilpotent algebras, $4$-dimensional commutative algebras and $5$-dimensional anticommutative over $ \mathbb C$. In particular, we correct several mistakes from the paper `Contractions low-dimensional Jordan algebras' by Ancochea Berm\'{u}dez, Fres\'{a}n Margalef Bentabol.

This study sought to clarify the composition of soil fungal and bacterial communities along an elevation gradient in arid montane ecosystem as well influence environmental factors (soil properties, climate, topography, plant diversity) upon microbial community structures. Four vegetation types—montane desert steppe (mean elevation: 1761 m), shrub 2077 subalpine coniferous forest 2485 2903 m)—we...

The aim of this investigation was to assess the differences in terms α-diversity, species composition and trophic structure between peracarid assemblages inhabiting artificial hard substrates those present on natural ones at two sites Western Mediterranean Sea. In each one, samples were collected from substrates, extracted peracarids identified level. Each sample characterised by its Total Abun...

in this study, species richness, evenness and vegetation biodiversity were investigated in stabilized and non-stabilized cut edge areas of chachkam district forest roads in sari forest of iran. 18 micro plots 1×1m (36 micro plots) were sampled to carry out this research on two cut edge areas. number of trees, shrubs and herbaceous were recorded in each micro-plot. significant difference was inv...
