Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...

This study aims to identify and determine species diversity and richness of the Gastropods of the intertidal zone of Bushehr seaport coastal area and assess the ecological status of this area using Welch index. Sampling was carried out at 6 stations in Bushehr seaport in the winter and summer seasons during 2013-2014. Bed sediment sampling was done three times in each station and Gastropod samp...

Methods Canopy fogging was used to sample beetles from 29 trees. The samples were statistically described using Schao and the Simpson diversity index D. Cluster analyses and multi-dimensional scaling (MDS) were performed. The taxonomic and guild structures of the Chilean coleopteran fauna were compared quantitatively with those found in other parts of the world using homogeneity chi-square and ...

some macroinvertebrate indices of stream health have been identified as most useful and efficacious. management decisions can be made with greater awareness.the objectives of this study were to assess the biological water of the hazar river using macroinvertebrates.the haraz river is one of the best freshwater ecosystems in the mazandaran province located in the north of iran.to assess the macr...

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...
