Traditional methods of dietary reconstruction do not allow the investigation of dietary variability within the lifetimes of individual hominins. However, laser ablation stable isotope analysis reveals that the delta13C values of Paranthropus robustus individuals often changed seasonally and interannually. These data suggest that Paranthropus was not a dietary specialist and that by about 1.8 mi...

The study included 144 fishes in Lake of 16 Tishreen Dam for detecting the infection with parasitic Protozoans, and determine distribution rate. Fishes were collected randomly once a month, during period from 22/12/2011 until 22/12/2012. Collected samples belonged to following species: Cyprinus carpio L., Varicorhinus damascinus, Garra rufa, Tilapia zillii, Liza abu. T. zillii was most prevalen...

Bycatch--the incidental catch of nontarget species--is a principal concern in marine conservation and fisheries management. In the eastern Pacific Ocean tuna fishery, a large fraction of nonmammal bycatch is captured by purse-seine gear when nets are deployed around floating objects. We examined the spatial distribution of a dominant species in this fishery's bycatch, the apex predator silky sh...

The movements, abundance, age composition and growth of bass, Dicentrarchus labrax (L.), in the Severn Estuary and inner Bristol Channel have been described from regular samples offish taken from power-station intake screens between 1972 and 1977. Bass began to move into the estuary during late August or September and reached peak abundance between September and early November. The tendency for...

in this study mercury was determined in canned tuna fish produced and distributed in iran after digestion by the standard methods of aoac. mercury contents in fish and canned tuna fish were determined by cold vapor atomic absorption spectrophotometry. the metal contents expressed in mg/kg wet weight for mercury varied from 0.017 to 0.394 (average of 0. 089) and 0.023 to 0.529 (average of 0.146)...

Elasmobranchs, the taxonomic group comprising sharks, skates and rays, play important roles in society and marine ecology but several species in this subclass are under threat.  This collection aims to be an open access hub for articles concerning all areas of elasmobranch biology and conservation. The collection is indefinitely open to further submissions and so will continue to grow as additi...

If you're even remotely up-to-date on your nutrition-for-health reading, you're well aware of the benefits of fish oil. Moreover, if you're anything like me, you've also gone to great lengths--often to no avail--to convince people that they should be taking it even if it does sound "icky." In an effort to save you and I a lot of future time and energy, I've compiled the following for you to sha...

The method of Garra and Baygorria, for localized antibody production, has been adapted for obtaining high-titered and monospecific antibodies against the murine toxin of Yersinia pestis. A hollow, perforated plastic golf ball surgically implanted under the skin of rabbits induced the formation of a granuloma. When the murine toxin of Y. pestis was injected directly into the granulomatous cavity...
