The Caloris basin, the youngest known large impact basin on Mercury, is revealed in MESSENGER images to be modified by volcanism and deformation in a manner distinct from that of lunar impact basins. The morphology and spatial distribution of basin materials themselves closely match lunar counterparts. Evidence for a volcanic origin of the basin's interior plains includes embayed craters on the...
We investigate the evolutionary history of the wide-ranging Nearctic treefrog Hyla arenicolor through the integration of extensive range-wide sampling, phylogenetic analyses of multilocus genetic data, and divergence dating. Previous phylogeographic studies of this frog documented a potential signature of introgressive hybridization from an ecologically and morphologically divergent sister spec...

the systematics, morphology, distribution, biology, economic importance and conservation of the perches of iran are described, the species are illustrated, and a bibliography on these fishes in iran is provided. there are three species, perca fluviatilis , sander lucioperca and s. marinus , found naturally in the caspian sea basin, with s. lucioperca translocated.
Some 78 specimencs of trout barb (Capoeta trutta) from four rivers of Bushehr Basin were caught by seine net to compare their morphology using geometric morphometrics. The specimens after anestethizing in 1% clove oil, were fixed in bufferd 10% formalin and transferred to the Isfahan University of Technology Ichthyology Museum for further studies. Geometric morphometric method were applied to a...
