The occurrence of three bony ray-finned fishes, Thorogobius ephippiatus (Lowe, 1839), Chlopsis bicolor Rafinesque, 1810, and Grammonus ater (Risso, 1810) is reported for the first time in scientific literature from Maltese coastal waters. leopard-spotted goby, T. , was mostly recorded within 8–32 m depth range on soft sediment rocky bottoms caves, but one individual a bottom with thin layer sil...

Giant suspension feeders such as mysticete whales, basking and whale sharks, and the extinct (indicated by '†') †pachycormiform teleosts are conspicuous members of modern and fossil marine vertebrate faunas. Whether convergent anatomical features common to these clades arose along similar evolutionary pathways has remained unclear because of a lack of information surrounding the origins of all ...

Relating environmental DNA (eDNA) signal strength to organism abundance requires a fundamental understanding of eDNA production. A number studies have demonstrated that production may scale allometrically—that is, larger organisms tend exhibit lower mass-specific rates, likely due allometric scaling in key processes related (e.g., surface area, excretion/egestion). While most previous examined ...

purpose: to determine the normal values of bony inter- and intra-orbital distances in an iranian adult population by orbital ct scan. methods: the study was conducted on all adults who were referred to farabi eye hospital from march 2003 to june 2005 for ct scan ordered for complaints unrelated to craniofacial or orbital abnormalities. patients were excluded in the presence of any pathology of ...

By living in a “world of water” fishes are exposed to major osmotic challenges that are opposite in nature in the freshwater and marine environments. In both cases, obligatory water fluxes primarily due to osmotic gradients across respiratory surfaces are threatening to the internal milieu and must be compensated by bulk flows of water in the opposite direction. While the ionoregulatory mechani...

ABSTRACT The piramutaba, Brachyplatystoma vaillantii is a freshwater catfish that the most abundant fishery resource in Amazon estuary. Piramutaba trawling done on industrial fishing scale and characterized by presence of many marine bycatch species, with without commercial value. Here we describe piramutaba estuary evaluate relationship two important environmental factors, depth salinity, acci...

The G-protein-coupled receptor GPR84, activated by medium-chain fatty acids, primarily expressed in macrophages and microglia, is involved inflammatory responses retinal development mammals amphibians. However, our understanding of its structure, function, tissue expression, signaling pathways fish limited. In this study, we cloned characterized the coding sequence GPR84 (ciGPR84) grass carp. A...
