| genetic structure and natal origins of immature hawksbill turtles (eretmochelys imbricata) in brazilian waters. | understanding the connections between sea turtle populations is fundamental for their effective conservation. brazil hosts important hawksbill feeding areas, but few studies have focused on how they connect with nesting populations in the atlantic. here, we (1) characterized mitochondrial dna control region haplotypes of immature hawksbills feeding along the coast of brazil (five areas ranging from equatorial to temperate latitudes, 157 skin samples), (2) analyzed genetic structure among atlanti ... | 2014 | 24558419 |
| nuclear markers reveal a complex introgression pattern among marine turtle species on the brazilian coast. | surprisingly, a high frequency of interspecific sea turtle hybrids has been previously recorded in a nesting site along a short stretch of the brazilian coast. mitochondrial dna data indicated that as much as 43% of the females identified as eretmochelys imbricata are hybrids in this area (bahia state of brazil). it is a remarkable find, because most of the nesting sites surveyed worldwide, including some in northern brazil, presents no hybrids, and rare caribbean sites present no more than 2% o ... | 2012 | 22780882 |
| trace elements distribution in hawksbill turtle (eretmochelys imbricata) and green turtle (chelonia mydas) tissues on the northern coast of bahia, brazil. | concentrations of elements (as, al, ba, ca, cd, co, cr, cu, fe, hg, k, mg, mn, mo, na, ni, pb, sb, se, sr, v, zn) were determined in liver, kidneys and bones of eretmochelys imbricata and chelonia mydas specimens found stranded along the northern coast of bahia, brazil. results showed that the concentrations of cd, cu, ni and zn in the liver and kidneys of juvenile c. mydas were the highest found in brazil. we also observed a significant difference (p<0.05) on the bioaccumulation of trace elemen ... | 2015 | 25796544 |
| attitudes and local ecological knowledge of experts fishermen in relation to conservation and bycatch of sea turtles (reptilia: testudines), southern bahia, brazil. | the use of ethnoecological tools to evaluate possible damage and loss of biodiversity related to the populations of species under some degree of threat may represent a first step towards integrating the political management of natural resources and conservation strategies. from this perspective, this study investigates fishermen's ecological knowledge about sea turtles and attitudes towards the conservation and bycatch in ilhéus, southern bahia, brazil. | 2013 | 23448503 |
