Gas Exchange in the Loggerhead Sea Turtle
Pulmonary CO diffusion capacity ( D L C O ) , lung volume (VL), oxygen uptake (Vo ) and pulmonary blood flow (QL) were measured simultaneously in the loggerhead sea turtle Caretta caretta (Linnaeus) (8—11 kg) using a gas rebreathing technique (syringe pump ventilation). Calculated D L C O and Vo values in the loggerhead turtle are approximately twice those of non-varanid reptiles and about 25 %...
متن کاملHow depth alters detection and capture of buried prey: exploitation of sea turtle eggs by mongooses
Predators are an important source of mortality for animals that lay their eggs in buried nests. We asked how depth alters the process of predation for buried prey. We outlined a general model of predation risk where depth may alter both prey detection and subsequent capture: deeper prey are detected less often because the strength of olfactory cues decreases with burial depth and, once detected...
متن کاملCombining Genetic and Ecological Data to Estimate Sea Turtle Origins
Many species of sea turtles spend part of their life cycle gathered in large feeding aggregations that combine individuals from widely separated rookery populations. Biologists have applied methods of mixed-stock analysis to mitochondrial DNA samples from rookeries and mixed populations to estimate the contributions of different rookeries to the mixed stock. These methods are limited by the amo...
متن کاملhazard evaluation of gas condensate stabilization and dehydration unit of parsian gas refinery using hazop procedures
شناسایی مخاطرات در واحد 400 پالایشگاه گاز پارسیان. در این پروزه با بکارگیری از تکنیک hazop به شناسا یی مخاطرات ، انحرافات ممکن و در صورت لزوم ارایه راهکارهای مناسب جهت افزایش ایمنی فرا یند پرداخته میگردد. شرایط عملیاتی مخاطره آمیز نظیر فشار و دمای بالا و وجود ترکیبات مختلف سمی و قابل انفجار در واحدهای پالایش گاز، ضرورت توجه به موارد ایمنی در این چنین واحدهایی را مشخص می سازد. مطالعه hazop یک ر...
Influence of the hydric environment on water exchange and hatchlings of rigid-shelled turtle eggs.
To examine the possible influence of incubation substrate water potential on rigid-shelled chelonian eggs and hatchlings, rigid-shelled eggs from four clutches of Brisbane River turtle (Emydura signata) were incubated buried in vermiculite at water potentials of approximately -100, -350, and -850 kPa, and patterns of egg mass change and hatchling attributes were examined. All eggs hatched succe...
