Tissue Distribution of Heavy Metals in Loggerhead Turtles (Caretta caretta).

Natal homing in juvenile loggerhead turtles (Caretta caretta).

Juvenile loggerhead turtles (Caretta caretta) from West Atlantic nesting beaches occupy oceanic (pelagic) habitats in the eastern Atlantic and Mediterranean, whereas larger juvenile turtles occupy shallow (neritic) habitats along the continental coastline of North America. Hence the switch from oceanic to neritic stage can involve a trans-oceanic migration. Several researchers have suggested th...

Ovarian Dynamics in Free-Ranging Loggerhead Sea Turtles (Caretta caretta)

Vitellogenin (VTG) is an egg yolk-precursor protein that serves as a nutrient source for developing embryos in oviparous vertebrates. The hormonal control of this protein has been studied in a variety of taxa, but details about the dynamics of this protein remain to be elucidated in sea turtle species. To investigate the dynamics of VTG in a multi-clutch species under natural conditions, 38 adu...

Two cases of pseudohermaphroditism in loggerhead sea turtles Caretta caretta.

Two juvenile (curved carapace lengths: 28 and 30 cm) loggerhead sea turtles Caretta caretta with precocious male external characteristics were admitted to the ARCA del Mar rescue area at the Oceanogràfic Aquarium in Valencia, Spain, in 2009 and 2010. Routine internal laparoscopic examination and subsequent histopathology confirmed the presence of apparently healthy internal female gonads in bot...

Baseline heavy metals and metalloid values in blood of loggerhead turtles (Caretta caretta) from Baja California Sur, Mexico.

Environmental pollution due to heavy metals is having an increased impact on marine wildlife accentuated by anthropogenic changes in the planet including overfishing, agricultural runoff and marine emerging infectious diseases. Sea turtles are considered sentinels of ecological health in marine ecosystems. The objective of this study was to determine baseline concentrations of zinc, cadmium, co...
