A new concern with the steel cage technique is interference with the normal development of the nestlings' magnetic sense due to the use of ferrous wire, which may disrupt the turtles' ability to navigate properly. [52] Trematodes of the family Spirorchiidae inhabit tissues throughout the body of the loggerhead, including vital organs, such as the heart and the brain. The air temperature should remain between 75-83°F, while the basking area should have a heater over it in order to ensure it reaches the mid 80s to low 90s Fahrenheit. Many researchers agree that temperature increases due to climate change has a complicated impact on turtles. Incubation temperatures generally range from 26–32 °C (79–90 °F). [90], Destruction and encroachment of habitat by humans is another threat to loggerhead sea turtles. 197-206 in P Meylan, ed.

Demography of a small population of loggerhead musk turtles (Sternotherus minor) in the panhandle of Florida. [50] Aggressive efforts to destroy foxes in the 1980s and 1990s has reduced this impact; however, it is estimated that it will be the year 2020 before populations will experience complete recovery from such dramatic losses.[51]. The Loggerhead Musk Turtle features a keeled carapace. In the coldest months, they submerge for up to seven hours at a time, emerging for only seven minutes to breathe. The mats of Sargassum contain as many as 100 different species of animals on which the juveniles feed.
