Stable isotopic comparison between loggerhead sea turtle tissues

Rapid Communications in Mass Spectrometry, 2014
RATIONALE Stable isotope analysis has been used extensively to provide ecological information about diet and foraging location of many species. The difference in isotopic composition between animal tissue and its diet, or the diet‐tissue discrimination factor, varies with tissue type ...

Migrations of the loggerhead sea turtle, Caretta caretta, into the Adriatic Sea [PDF]

, 2000
Data on migrations of sea turtles in the Adriatic Sea are extremely rare. In the first 10 years of the implementation of tagging programs in the Mediterranean basin (1981/82-1992), 13 tagged loggerheads were recaptured in the Adriatic Sea, only 4 being reported from Croatian waters.

Physiologic and clinicopathologic effects of crude oil on loggerhead sea turtles

Archives of Environmental Contamination and Toxicology, 1995
The physiologic and clinicopathologic effects of weathered South Louisiana crude oil exposure were studied in the laboratory in juvenile loggerhead sea turtles. Sea turtles ingested oil incidentally, and oil was observed clinging to the nares, eyes, and upper esophagus, and was found in the feces.

Effects of brevetoxin exposure on the immune system of loggerhead sea turtles

Aquatic Toxicology, 2010
Blooms of the toxic dinoflagellate, Karenia brevis, occur almost annually off the Florida coast. These blooms, commonly called "red tides", produce a group of neurotoxins collectively termed brevetoxins. Many species of sealife, including sea turtles, are severely impacted by brevetoxin exposure. Effects of brevetoxins on immune cells were investigated

Loggerhead sea turtles as bioturbators in marine ecosystems

2008
The northern Adriatic Sea is one of the most important foraging habitats for loggerhead sea turtle (Caretta caretta) in the Mediterranean. Its shallow continental shelf, favorable sea temperatures and rich benthic communities constitute feeding areas for loggerheads in neritic stage.

Monitoring Mercury in the Loggerhead Sea Turtle, Caretta caretta

Environmental Science & Technology, 2004
The validity of using blood samples and keratinized scutes for nonlethal routine monitoring of mercury (Hg) in loggerhead sea turtles, Caretta caretta, is evaluated in the context of how effectively these matrixes predict internal tissue Hg burdens and the different temporal scales of exposure they represent.

Magnetoreception Abilities in Juvenile Loggerhead Sea Turtles

2017
Loggerhead sea turtles (Caretta caretta) complete extensive, open-ocean migrations around the North Atlantic subtropical gyre current system over the course of many years. Evidence suggests that magnetoreception, or the ability to detect the Earth’s magnetic field, plays a role in their ability to navigate large, open areas lacking obvious cues.

Assessing microplastics contamination in unviable loggerhead sea turtle eggs

Science of The Total Environment
Sea turtles, in comparison with marine mammals, sea birds, and fishes, are the most affected by microplastics in terms of number of individuals impacted and concentration within each organism. The ubiquitous nature and persistence of microplastics in the environment further compromises sea turtles as many species are currently vulnerable, endangered ...
