a survey was performed to investigate the fauna of ichneumonidae in fars province during 2012 to 2013. totally, 14 species belonging to 13 genera and six subfamilies were collected and identified including: exetastes adpressorius (thunberg, 1822) (banchinae); diadegma semiclausum (hellén, 1949) (campopleginae); cryptus inculcator (linnaeus, 1758); dichrogaster saharator (aubert, 1964) (cryptina...

— New synonymy is proposed as follows: Pityokteines Fuchs { = Orthotomides Wood), Araptus foveifrons (Schedl) { = interjectus Wood), n. comb., Cryptocarenus seriatus Eggers { = bolivianus Eggers), Hylastes gracilis LeConte {=asper Swaine), Procryphalus utahensis Hopkins {=aceris Hopkins), Scolytodes maurus (Blandford) {=Hexacolus ellipticus Eggers), Scolytus hermosus Wood {=sylvaticus Bright), ...

A pair of fly impressions is described as a new species of a new genus, Orientisargus illecebrosusgen. et sp. n., referred to a new family Orientisargidaefam. n. within Archisargoidea of Brachycera, Diptera. The systematic position of Orientisargidae is discussed. Daohugosargusgen. n. is proposed for Sharasargus eximius KY Zhang et al., 2008. Uranorhagionidae is a junior synonym for Archisargid...

This study describes the daily activity in a simulated high tide situation of four species of hermit crabs (Pagurus criniticornis, Clibanarius antillensis, C. sclopetarius, and C. vittatus) that coexist in an intertidal flat in southeastern Brazil. Observations were done in two-hour intervals during two subsequent days (48 h) in three replicate pools with thirty crabs each. Among species (betwe...

A characterization of the occupied shells by the hermit crab Clibanarius vittatus was carried out. Hermit crabs were collected in the intertidal zone, during the low spring tide monthly from April 2005 to March 2006. They were sexed and their cephalothoracic shield length (CL) was measured. Shells were identified, dried, weighed and the aperture length (AL) and width (AW) were measured. 1187 cr...

Heavy metals are one of the most serious pollutants in the environment due to their toxicity, persistence and ability to concentrate along the food chain. Water bodies contaminated by heavy metals may lead to bioaccumulation in the food chain of an estuarine environment. Contamination of natural waters by heavy metals negatively affects aquatic biota and poses considerable environmental risks a...
