Sea Turtle Research - Sea Turtle Facts and Information - Fibropapillomatosis is a disease specific of sea turtles that produce benign tumors mainly in the outer tissues that affect their health. This condition is subject to research because the cause of their appearance is unknown. The best hypothesis is that an herpesvirus causes this disease but how they get it is not determined. Some scientists think that leeches, snails or some other type of marine organism are the transmitters of this virus as they have a constant relation with ...

(EDCs) affect gonadal development in reptiles, especially turtles. Among EDCs, we focus on PCBs, BPA, pesticides like atrazine, nitrates, and heavy metals. We also consider whether adaptation might be possible in the face of persistent chemical insult and conclude that, while plausible, contemporary ...

ADW: Emys orbicularis: INFORMATION - These turtles attack and capture their prey, biting with a sideward turn of the head, then tearing the prey to pieces with sharp claws on the forelimbs. Generally, in the wild, their prey must be moving to be seized. In captivity, these turtles may resort to eating fruits and vegetables. (Gadow, 1958) Primary Diet; carnivore. piscivore; insectivore

The origin of turtles: A paleontological perspective ... - Turtles are one of the oldest known sauropsid orders that appeared about 240 million years ago. Within the vertebrates, they have evolved the most unusual body plan, with most of their body inside ...

However, increased commercializa-tion of sea turtle products over the course of the 20th century has decimated many populations. Because sea turtles have complex life cycles during which indi-

Research Article - Inducing Turtles - Five (11%) turtles required a second injection of 10-15 units the same day or the next day before they would lay all their eggs. Seven (16%) required a total of three doses over 2-3 days before they laid all their eggs. Three turtles (7%) never laid all their eggs despite a total of 3-4 doses. Two captive specimens that had been kept in aquariums laid double clutches made up of 5-8 hypercalcified eggs and 5-8 normally shelled eggs.

Green turtle fibropapilloma: An epidemiologic perspective - All turtles were measured and examined, and the overall severity of the disease was rated by the size, number, and location of external fibropapilloma tumors. Hematocrit, total protein, and ...

Morphology and Evolution of Turtles | SpringerLink - Turtles are a focus of his research because they offer unique insights into the patterns of distribution of Mesozoic vertebrates in general and the degree to which faunal interchange between separate areas were possible. He am particularly interested in using information from turtles to elucidate questions of interchange between Asia and North America and latitudinal zonation of North America during the Cretaceous.

Saving Sea Turtles - An Intern's Perspective - The Ocean ... - Sea turtles are usually in what is called a "trance" while nesting so they are not as bothered by the lights or small disturbances that may occur while we record the data. If we were lucky, the turtle would be digging its nest and we could more easily measure the final depth of that nest and effortlessly gather the eggs as she laid them. If not, then we would wait by the side as the turtle buried and compacted the nest before heading back to sea. After we returned back to the ...

Marine turtle conservation | Environmental sustainability ... - Saving turtles is good for tourism and the local economy. The first year, 50 nests were protected on the beaches of Velas. The conservation program has since spread across the entire Maharashtra coastline. Since 2010, around 150 nests have been protected, with 8,290 hatchlings successfully released. Even villagers who once relied on eggs for income recognize the importance of protecting the ...

All About Sea Turtles - Conservation & Research | SeaWorld ... - In this case, the receiver or hydrophone is on board a research vessel, and the tagged turtles are tracked real-time, usually as they move around a specific area such as a bay or estuary. Acoustic tags have a battery life of up to four years (longer than satellite tags) and are the only tag type that tracks a sea turtle's underwater movement in such detail. This is an excellent way to track hundreds of sea turtles within a given area to see how much a sea turtle uses that particular area ...

(PDF) The origin of turtles: A paleontological perspective ... - Turtles are the notable exception to the rule, because the formation of the shell precludes movement between the ribs. Instead, turtles rely on a unique system formed by two pairs of antagonistic abdominal muscles, the M. transversus and M. obliquus abdominis (Gaunt and Gans, '69;Brainerd and Owerkowicz, 2006). Paleontologists have puzzled over the origin of this breathing mechanism (Rieppel and Reisz,'99), but few insights have been produced on how this breathing system might have ...

ADW: Amyda cartilaginea: INFORMATION - Adolescent turtles between 3-5 years old have large tubercles on their carapace and very vibrant yellow spots on their head and neck. Large adult turtles around 8-10 years old lose the tubercles to a smooth carapace, and the yellow spots fade into lines on the adult's green head. The growth of the turtles slows as it gets older and then is ...

Sea Turtles Research Papers - - Emerging research is revealing important associations between vegetated coastal wetlands and marine megafauna, such as cetaceans, sea turtles, and sharks. But these links have not been reviewed and the importance of these globally declining habitats is undervalued. Here, we identify associations for 102 marine megafauna species that utilize these habitats, increasing the number of species with ...

The diapsid origin of turtles - Invited Perspectives ... - As has long been postulated on the basis of molecular data, turtles evolved from diapsid reptiles and are more closely related to extant diapsids than to parareptiles, which had been suggested as stem group by some paleontologists. The turtle cranium with its secondarily closed temporal region represents a derived rather than a primitive condition and the plastron partially evolved through the fusion of gastralia.

Testudines - Tree of Life Web Project - Turtles are herbivorous, carnivorous and omnivorous. The majority of turtles are omnivorous, but many have highly specialized diets. Certain land tortoises and sea turtles are strict herbivores, and one marine species has the capacity to digest cellulose. Other marine species are specialists on jellyfish (the leatherback) and sponges (the hawksbill). Turtles of several families specialize on mollusks and have broadly expanded jaws for crushing their prey. Others that specialize on swimming ...
