Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

Thursday, 22 January 2009 a Billion Frogs on World's
Thursday, 22 January 2009 A billion frogs on world's plates How amphibians are harvested around the world Up to one billion frogs are taken from the wild for human consumption each year, according to a new study. Researchers arrived at this conclusion by analysing UN trade data, although they acknowledge there is a lot of uncertainty in the figure. France and the US are the two biggest importers, with significant consumption in several East Asian nations. About one-third of all amphibians are listed as threatened species, with habitat loss the biggest factor. But hunting is acknowledged as another important driver for some species, along with climate change, pollution and disease - notably the fungal condition chytridiomycosis which has brought rapid extinctions to some amphibians. Absence of essential data to monitor and manage the wild harvest is a large concern Professor Corey Bradshaw The new research, to be published in a forthcoming edition of the journal Conservation Biology, suggests that the global trade in wild frogs has been underestimated in the past. "Frogs legs are on the menu at school cafeterias in Europe, market stalls and dinner tables across Asia to high end restaurants throughout the world," said Corey Bradshaw from Adelaide University in Australia. "Amphibians are already the most threatened animal group yet assessed because of disease, habitat loss and climate change - man's massive appetite for their legs is not helping." Amphibians are farmed for food in some countries but these animals are not included in the new analysis. Exporting extinction Indonesia emerged from Professor Bradshaw's analysis as both the largest exporter of frogs - 5,000 tonnes per year - and a major consumer. -

Photocredit: Adam Backlin (USGS). U.S. Fish and Wildlife Service Carlsbad Fish and Wildlife Office Carlsbad, California July 13, 2012 2012 5-year Review for mountain yellow-legged frog 5-YEAR REVIEW mountain yellow-legged frog (Rana muscosa) Southern California Distinct Population Segment I. GENERAL INFORMATION Purpose of 5-year Reviews: The U.S. Fish and Wildlife Service (Service) is required by section 4(c)(2) of the Endangered Species Act (Act) to conduct a status review of each listed species at least once every 5 years. The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing of a species as endangered or threatened is based on the existence of threats attributable to one or more of the five threat factors described in section 4(a)(1) of the Act, and we must consider these same five factors in any subsequent consideration of reclassification or delisting of a species. In the 5-year review, we consider the best available scientific and commercial data on the species, and focus on new information available since the species was listed or last reviewed. -

In this study, the life history traits of the Anatolian lizard Apathya cappadocica were examined from 3 populations from different altitudes (Kilis, 697 m; Şanlıurfa, 891 m; Diyarbakır, 1058 m) from southeastern Anatolia, Turkey. Age structure was determined by using skeletochronology. Males in all populations were the larger sex; therefore, the populations showed male biases that were negative by the sexual size dimorphism index. Males in Diyarbakır (high altitude) were also younger than males in the other populations. There were no significant differences between the males and females of all 3 populations in terms of either age or snout– vent length except in the Şanlıurfa population, in which males were larger than females.

Progress and Prospects for Studies on Chinese Amphibians
Asian Herpetological Research 2010, 1(2): 64-85 DOI: 10.3724/SP.J.1245.2010.00064 Progress and Prospects for Studies on Chinese Amphibians FEI Liang, YE Changyuan and JIANG Jianping* Chengdu Institute of Biology, Chinese Academy of Sciences, Chengdu 610041, Sichuan, China Abstract This work summarizes the history and progress of the studies on Chinese amphibians since they first ap- peared in the Chinese literature. A wide range of research has been carried out, including the history of the definition of amphibians, faunal surveys, systematic research, ecological research, biochemical research (isozyme and other proteins or peptides, chromosomes, DNA), anatomical research, embryological research, phylogenetic and zoogeographical re- search, and many others such as ultrastructure of organs, crossbreeding test, regeneration of organs, abnormality survey, acoustics, fossils, sperm ultrastructure and parasites. In addition, the prospects for studies on Chinese amphibians in future are proposed in this paper. Keywords progress, prospect, faunal survey, systematics, amphibian, China 1.

Reptile species Received: 14/01/2018 were identified from collections made during field studies or recorded in literature, with some Accepted: 18/06/2018 new locality records obtained. Field studies were undertaken over two consecutive years (2016 and 2017). Two lacertid species, one skink species, two colubrid species and one viper species were officially recorded for the first time or their information was updated. In addition to Keywords species locality records, chorotypical and habitat selection were also assessed and the Viper International Union for Conservation of Nature Red List of Threatened Species criteria Reptilia included. Data on the distribution and locality information for each taxon is also provided. Our Fauna findings demonstrate that Amasya might be an ecotone zone between the Mediterranean, Chorotype Caucasian, and European ecosystems. Although there are some concerns for the sustainable Eunis dynamics of reptilian fauna, relatively rich and different European nature information system habitat types provide basic survival conditions for reptilian fauna in the province. 1. INTRODUCTION Turkey is the only country that almost entirely includes three of the world’s 34 biodiversity hotspots: the Caucasus, Irano-Anatolian, and Mediterranean [1]. -
