Little is known about how specific anthropogenic hazards affect the biology of organisms. Quantifying the effect of regional hazards is particularly challenging for species such as sea turtles because they are migratory, difficult to study, long lived, and face multiple anthropogenic threats. Expert elicitation, a technique used to synthesize opinions of experts while assessing uncertainty arou...

Two sea turtle species nest in the Mediterranean, the green turtle and the loggerhead turtle. Leatherbacks are widely distributed in the Mediterranean, although they do not have any permanent nesting area. Two other species, the hawksbill and the Kemp’s ridley turtle only occur occasionally. Available information on sea turtle populations in the Mediterranean Sea, including distribution, popula...

Despite increased efforts from government agencies, scientists, and non-government organizations over the past few decades, anthropogenic sources of sea turtle mortality continue to threaten the survivorship of sea turtle species around the globe. More recent efforts to engage local people with community-based sea turtle conservation programs have been based primarily on economic incentives and...

Many sea turtle populations are below 10% of their pre-Columbian numbers [1-4]. Though historic and systematic over-exploitation is the principal cause of these declines, sea turtles face similar threats today. Adults and juveniles are actively hunted and commercial fisheries catch them incidentally. Nesting suffers from beach development, egg poaching and the poaching of nesting females. Accom...

Speckled shrimp (Metapenaeus monoceros), is a commercially important prawn in the embayments and estuaries of the Mediterranean Sea. It is originally a Lessepsian species which had migrated from the Red Sea into the Mediterranean Sea through the Suez Canal. This study was carried out in the North-eastern Mediterranean Sea between November 2009 and October 2010 with monthly sampling of speckled ...

This study describes the reproductive cell development and ovarian developmental stages, identifies nongerminal components of white shrimp (Penaeus schmitti) caught off southern coast Espírito Santo, Brazil. P. schmitti specimens were collected monthly from March 2019 to February 2020, by artisanal fishing. All shrimps analyzed macroscopically (n = 181) females randomly selected 154) for histol...

Five sea turtle species, all globally threatened, are found in southern Mozambican waters. Illegal hunting of foraging turtles, nest raiding and modification of coastal habitat are assumed to affect local sea turtle populations, but a lack of capacity and resource constraints hamper monitoring and compliance activities. Enlisting the recreational SCUBA diving community to report sea turtle sigh...

All seven extant species of sea turtles are considered endangered or threatened with extinction. Because of their commercial value for food (particularly the green turtle) and for craft materials (bekko or tortoiseshell from the hawksbill turtle) they have been heavily exploited around the world. Sea turtles are also charismatic animals to view in large aquaria and three species have proven eas...

a total of 3528 specimens of freshwater turtles belonging to two families viz., geoemydidae (brown river turtle, kachuga smithi; indian saw-backed turtle, k. tecta; brahminy rrive turtle, hardella thurgi; spotted pond turtle, geoclemys hamiltonii) and trionychidae (indian soft-shell turtle, aspederates gangeticus; peacock soft-shell turtle, a.hurum; narrow-headed soft-shell turtle, chitra indic...
