in this study, the systematic position of acanthalburnus microlepis from kura and aras basins is clarified and some notes on the taxonomy of the acanthobrama species distributed in turkey are given. based on the morphological and osteological analyses, a high similarity between a. microlepis and acanthobrama members is found. some taxonomic information yielded from the examination of recent col...

background: caddisflies have significant roles in freshwater ecosystems. morphological identification is the major impediment in accurate species identification of hydropsychids. mitochondrial and nuclear markers are suitable for molecular systematics of these group of arthropods. methods: trichopteran specimens of lavasan district in northeastern tehran, iran were collected in 2012, and de­scr...

The compatibility of vanadium (V) during mantle melting is a function of oxygen fugacity (fO2): at high fO2’s, V becomes more incompatible. The prospects and limitations of using the V content of peridotites as a proxy for paleo-fO2 at the time of melt extraction were investigated here by assessing the uncertainties in V measurements and the sensitivity of V as a function of degree of melt extr...
