Abstract Here, we present results from a study conducted in two major shrimp fishing grounds the Northeastern Brazil Marine Ecoregion (NBME) that determined reproductive dynamics of penaeid shrimps Xiphopenaeus kroyeri and Penaeus schmitti . We aimed to verify if current closed season is appropriate untangle environmental drivers control their dynamics. The periods recruitment reproduction both...

Sea turtles are widely distributed in temperate and tropical seas, and their carapace is often colonized by species of macroalgae. There have been several studies on the epibionts of loggerhead turtles, Caretta caretta Linnaeus, from different parts of the world (KITSOS, et al., 2005; PFALLER et al., 2006, 2008). The carapaces of loggerhead turtles represent an important substratum for a variet...

K ridley turtles (Lepidochelys kempii) are an endangered sea turtle species found in waters of the southern United States and Mexico. Juveniles of this species are known to seasonally inhabit waters as far north as New England. In autumn, juvenile Kemp’s ridley turtles may become debilitated in the northwestern Atlantic ocean as water temperatures rapidly decrease and animals are forced to shor...

Underwater sound was recorded in one of the major coastal foraging areas for juvenile sea turtles in the Peconic Bay Estuary system in Long Island, New York. The recording season of the underwater environment coincided with the sea turtle activity season in an inshore area where there is considerable boating and recreational activity, especially during the summer between Independence Day and La...

The seven species of sea turtles occupy a diversity of niches, and have a history tracing back over 100 million years, yet all share basic life-history features, including exceptional navigation skills and periodic migrations from feeding to breeding habitats. Here, we review the biogeographic, behavioural, and ecological factors that shape the distribution of genetic diversity in sea turtles. ...

We investigated the utility of diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) for the analysis and identification of sea turtle (Family Cheloniidae) and bovid (Family Bovidae) keratins, commonly used to manufacture historic artefacts. Spectral libraries are helpful in determining the class of the material (i.e., keratin versus plastics), but do not allow for inferences abo...

Sea turtle nesting presents a potential pathway to subsidize nutrient-poor dune ecosystems, which provide the nesting habitat for sea turtles. To assess whether this positive feedback between dune plants and turtle nests exists, we measured N concentration and delta15N values in dune soils, leaves from a common dune plant (sea oats [Uniola paniculata]), and addled eggs of loggerhead (Caretta ca...
