Cloacae, Cloacal Glands and Female Sperm Storage in Giant Salamanders
Most of the 620+ species of salamanders are relatively small animals, rarely exceeding 200 mm total length, but members of the families Cryptobranchidae (1800 mm), Sirenidae (978 mm), Amphiumidae (1162 mm), Proteidae (486 mm) and Dicamptodontidae (351 mm) can truly be considered "giant salamanders." These families have few species (Proteidae with six species is the most speciose) and are aquati...
متن کاملDynamics of habitat changes as a result of climate change in Zagros Mountains Range (Iran), a case study on Amphibians
Climate change is currently considered a serious threat for many species and recognized as one of the most important factors in the global biodiversity loss. Among animal groups, amphibians are known to be among the most sensitive groups of vertebrates to climate change due to their inability to travel long distances, and mountain habitat species are more exposed to climate change pressures tha...
متن کاملReintroduction and Post-Release Survival of a Living Fossil: The Chinese Giant Salamander
Captive rearing and reintroduction / translocation are increasingly used as tools to supplement wild populations of threatened species. Reintroducing captive-reared Chinese giant salamanders may help to augment the declining wild populations and conserve this critically endangered amphibian. We released 31 captive-reared juvenile giant salamanders implanted with VHF radio transmitters at the He...
متن کاملPronounced Peramorphosis in Lissamphibians—Aviturus exsecratus (Urodela, Cryptobranchidae) from the Paleocene–Eocene Thermal Maximum of Mongolia
BACKGROUND The oldest and largest member of giant salamanders (Cryptobranchidae) Aviturus exsecratus appears in the latest Paleocene (near the Paleocene-Eocene Thermal Maximum) of Mongolia. Based on femoral and vertebral morphology and metrics, a terrestrial adaptation has been supposed for this species. METHODOLOGY/PRINCIPAL FINDINGS A detailed morphological reinvestigation of published as w...
متن کاملGeobiological constraints on Earth system sensitivity to CO₂ during the Cretaceous and Cenozoic.
Earth system climate sensitivity (ESS) is the long-term (>10³ year) response of global surface temperature to doubled CO₂ that integrates fast and slow climate feedbacks. ESS has energy policy implications because global temperatures are not expected to decline appreciably for at least 10³ year, even if anthropogenic greenhouse gas emissions drop to zero. We report provisional ESS estimates of ...
