چکیده
their disciplines, it seemed a possibly useful contribution to write a book that would draw from all the relevant disciplines about the past, from primatology to historical linguistics, with genetics as the common thread to weave all these findings together into a coherent narrative. I was amazed at how much detail can now be filled in on the largely blank pages of human prehistory extending from 50,000 to 5,000 years ago, much of which one might think was utterly beyond recovery.

Evaluation of hematological and plasma biochemical parameters in green sea turtle (Chelonia mydas Linnaeus, 1758) from nesting colonies of the northern coast the Sea of Oman
The green turtle (Chelonia mydas) has been a species of global concern for decades. As an attempt to study health status of nesting green turtles, Blood biochemistry and hematological values were obtained from 18 clinically normal, nesting female green sea turtles on the northern coast of the sea of Oman. Mean curved carapace length (CCL) was 111±4 cm with a range of 103—122 cm. Barnacles were ...
متن کاملCancer in sea turtles.
Sea Turtles Sea turtles are one of the oldest extant groups of animals, and they have changed little in basic anatomy for millions of years. Sea turtles are found throughout the world, and depending on the species, range from warm tropical water to frigid oceans near the arctic. They can be herbivores, omnivores, or carnivores and can be quite large. For example, the largest species of sea turt...
متن کاملMetallothionein biosynthesis as a detoxification mechanism of heavy metals (Hg,Cd,Pb,Cu,Zn) in green sea turtles (Chelonia mydas)
In this study, heavy metals (Hg,Cd,Pb,Cu,Zn) and metallothionein (MT) biosynthesis were measured in blood of green sea turtles (Chelonia mydas) nesting on the northern coast of the Sea of Oman. Heavy metals concentrations in the sea water, the sediments, the blood samples ranged between 0.02-8.43 μg/l, 0.06-10.32 μg/l, and 0.16-36.78μg/g (ww), respectively.The highest concentration...
متن کاملReference intervals and relationships between health status, carapace length, body mass, and water temperature and concentrations of plasma total protein and protein electrophoretogram fractions in Atlantic loggerhead sea turtles and green turtles.
OBJECTIVE To determine reference intervals for concentrations of plasma total protein (TP) and electrophoretogram fractions (ELFs) for healthy, wild loggerhead sea turtles (Caretta caretta) and green turtles (Chelonia mydas) and to assess relationships between TP and ELF concentrations and health status, body size, body mass, and water temperature. DESIGN Evaluation study. ANIMALS 437 healt...
متن کاملBiology of sea turtles under risk from tiger sharks at a foraging ground
It is important to understand the population structure and space use of sea turtles because of their potential effects on the dynamics of nearshore ecosystems. Much of our current understanding is skewed because the ecology of sea turtles on their foraging grounds is known best from areas where there are, or have been, major human impacts. We studied green Chelonia mydas and loggerhead Caretta ...
متن کاملSeasonal Variation in Sea Turtle Density and Abundance in the Southeast Florida Current and Surrounding Waters.
Assessment and management of sea turtle populations is often limited by a lack of available data pertaining to at-sea distributions at appropriate spatial and temporal resolutions. Assessing the spatial and temporal distributions of marine turtles in an open system poses both observational and analytical challenges due to the turtles' highly migratory nature. Surface counts of marine turtles in...
