Mauremys rivulata (Family Geoemydidae) is a medium-sized freshwater turtle inhabiting various natural and manmade habitats, including rivers, seasonal ponds, lakes, brackish coastal lagoons, irrigation canals, reservoirs. In this study, the morphology of four different populations in Çanakkale was evaluated between sexes. The straight carapace length (SCL), width (CW), plastron (PL), (PW), body...

Cadmium accumulation by the haemolymph, gills and carapace of the shore crab Carcinus maenas (L.) was significantly higher in dilute sea water. This was reflected in the whole-body cadmium concentrations. There was no salinity effect with the hepatopancreas or muscle cadmium concentration. Over a 68-day period, cadmium was steadily accumulated by the carapace, with the salinity effect becoming ...

The Thermosbaenacea, a small taxon of crustaceans inhabiting subterranean waters, are unique among malacostracans as they brood their offspring dorsally under the carapace. This habit is of evolutionary interest but the last detailed report on thermosbaenacean development is more than 40 years old. Here we provide new observations on an ovigerous female of Tulumella unidens with advanced develo...

Petrolisthes paulayi sp. n. is described from specimens collected in French Polynesia. The new species belongs to an assemblage of morphologically similar Indo-West Pacific (IWP) species, here designated as the "mesobranchial-spine group". All species in the group bear carapace spines, including one or more mesobranchial spines, and transverse, piliferous striations on the dorsal surface of car...

A significant tin deposit has been identified in the northeast part of the Late Proterozoic Arabian Shield. Cassiterite-topaz-quartz greisens are distributed over 16 km2 in flat-topped cupolas of a highly evolved, zinnwaldite-bearing alkali-feldspar granite which composes part of the silsilah ring complex (lat 26"06'N, long 4240'E). The 587 m.y. old alkali-feldspar granite is overlain by a cara...

Abstract Although Carcinus maenas as a species is widely studied, research focusing on fecundity still scarce. The main objective of this study was to evaluate size-fecundity relationships across different lagoons and estuaries, along the Portuguese coast, understand how local environment affects reproductive patterns. Between 2019 2020, ovigerous females were collected from Southern (Ria Formo...

The second known agostocaridid shrimp, Agostocaris bozanici, is described from a cenote on Cozumel Island. The new species is characterized by having a dorsally unarmed rostrum, and 5 pairs of lateral, and 5 pairs of posterior spines on the telson. A new genus and species of hippolytid, Yagerocaris cozumel, is described from a different cenote and an anchialine cave on Cozumel. The genus is cha...

The freshwater prawn Macrobrachium jelskii (Miers, 1877) is a species with wide geographical distribution. However, the biological and ecological aspects of this are poorly studied. Thus, present study was carried out in Batateiras River, at municipality Juazeiro do Norte, located south Ceará, semiarid region northeastern Brazil. Samples were monthly between January December 2013, along river m...

Knowledge of green turtle ( Chelonia mydas ) foraging ecology in the northwestern Gulf Mexico (GOM) is critical as populations begin to recover from heavy harvesting prior centuries. We present a comprehensive long-term assessment diets carcasses salvaged 1987 2014 along Texas coast. Digestive tract contents were examined 420 turtles, ranging size 7.3 86.0 cm straight carapace length (SCL max )...

Norway lobster (Nephrops norvegicus) is one of the most valuable shellfish resources in Mediterranean and northeast Atlantic. Sustainable management its fishery require long-term scientific monitoring stocks. Population dynamics, fishery, exploitation status were studied over a long time series (between 2008 2014) semi enclosed gulf Easter (Pagasitikos Gulf). Sampling was carried out using comm...
