A New Species of Amolops from Thailand (Amphibia, Anura, Ranidae)
ZOOLOGICAL SCIENCE 23: 727–732 (2006) 2006 Zoological Society of Japan A New Species of Amolops from Thailand (Amphibia, Anura, Ranidae) Masafumi Matsui1* and Jarujin Nabhitabhata2 1Graduate School of Human and Environmental Studies, Kyoto University, Sakyo-ku, Kyoto 606-8501, Japan 2National Science Museum, Technopolis, Klong 5, Klongluang District, Pathun thani 12120, Thailand We describe a new species of torrent-dwelling ranid frog of the genus Amolops from western to peninsular Thailand. Amolops panhai, new species, differs from its congeners by the combination of: small body, males 31–34 mm, females 48–58 mm in snout-vent length; head narrower than long; tympanum distinct; vomerine teeth in short, oblique patches; first finger subequal to second; disc of first finger smaller than that of second, with circummarginal groove; no wide fringe of skin on third finger; toes fully webbed; outer metatarsal tubercle present; supratympanic fold present; dor- solateral fold indistinct; axillary gland present; horny spines on back, side of head and body, and chest absent; large tubercles on side of anus absent; glandular fold on ventral surface of tarsus absent; nuptial pad and paired gular pouches present in male; white band along the upper jaw extending to shoulder absent; larval dental formula 7(4-7)/3(1). This new species is the second anu- ran discovered which has a disjunct distribution around the Isthmus of Kra.

Riparian Management and the Tailed Frog in Northern Coastal Forests
Forest Ecology and Management 124 (1999) 35±43 Riparian management and the tailed frog in northern coastal forests Linda Dupuis*,1, Doug Steventon Centre for Applied Conservation Biology, Department of Forest Sciences, University of British Columbia, Vancouver, BC, Canada V6T 1Z4 Ministry of Forests, Prince Rupert Region, Bag 5000, Smithers, BC, Canada V0J 2N0 Received 28 July 1998; accepted 19 January 1999 Abstract Although the importance of aquatic environments and adjacent riparian habitats for ®sh have been recognized by forest managers, headwater creeks have received little attention. The tailed frog, Ascaphus truei, inhabits permanent headwaters, and several US studies suggest that its populations decline following clear-cut logging practices. In British Columbia, this species is considered to be at risk because little is known of its abundance, distribution patterns in the landscape, and habitat needs. We characterized nine logged, buffered and old-growth creeks in each of six watersheds (n 54). Tadpole densities were obtained by area-constrained searches. Despite large natural variation in population size, densities decreased with increasing levels of ®ne sediment (<64 mm diameter), rubble, detritus and wood, and increased with bank width. The parameters that were correlated with lower tadpole densities were found at higher levels in clear-cut creeks than in creeks of other stand types. Tadpole densities were signi®cantly lower in logged streams than in buffered and old-growth creeks; thus, forested buffers along streams appear to maintain natural channel conditions. To prevent direct physical damage and sedimentation of channel beds, we suggest that buffers be retained along permanent headwater creeks. Creeks that display characteristics favoring higher tadpole densities, such as those that have coarse, stable substrates, should have management priority over less favorable creeks. -

I Found a Frog…
I Found a Frog…What Do I Do With It? Finding a frog or toad in your backyard is a great discovery, especially if you live in an urban setting where these creatures are rarely found. Unless you have a large pond, most frogs and toads we find are transients taking up temporary residence where food and habitat seem good. But when autumn rolls around, starts to cool off, and the frog has not left, what do you do with your little friend? Here is some advice: Does this mean I have a new pet frog or toad? No! Please do not take in the animal. Not only is this illegal, but this is a wild animal that will not do well in a captive environment. Also, the proper artificial habitat is expensive, combined with the cost of food for the winter. And if you get attached to the animal (which is difficult not to do), it will be more difficult to release it in the spring. Many of the animal’s special survival skills will be lost in captivity over the winter. Frogs and toads hibernate in the winter, and rest their bodies for the following summer season. Frogs will want to slow down as daytime temperatures and lengths decrease, but it is not cool enough in our homes to lower metabolic rates. As a result, the frog remains active, will not eat, and will slowly starve. Some frogs with specialized care and live food will change their natural cycles and begin to feed, but if yours does not, it will die unnecessarily. -

Species Account
SPECIES ACCOUNT AMPHIBIA I. Family MEGOPHRYIDAE Megophrys acera s Horned Frog This was a leaf litter frog, which inhabited forest floor of closed-canopy evergreen forests at Gunung Tujuh. It occurs from the lowlands at about 750 meters asl up to mountain forests over 1500 meters asl (Mistar, 2003). At Gunung Tujuh it was found at elevation 1200 meters asl. This is a rare species, which was only found at Gunung Tujuh survey site. This species is known from Peninsular Thailand through most of Peninsular Malaysia (Berry, 1975) and Sumatra (Mistar, 2003). Figure 21. M. aceras from Gunung Tujuh (Photograph by J. Holden). Megophrys nasuta Bornean Horned Frog, Malayan Horned Frog, Horned Toad, Large Horned Frog It was a leaf litter frog, which inhabited intact lowland and sub mountain rainforest, generally near forest streams. Adults are terrestrial in habits, but tadpoles live in clear forest streams. It occurred about 500 meters asl up to 1000 meters asl. It was regularly encountered, and its characteristic call was frequently heard in suitable habitat. It was uncommon in Tapan, Lumayang, Sungai Durian, Muara Kambang, Muara Sako, Muara Labuh and Lubuk Selasih survey sites. This species is known from southern, throughout Peninsular Malaysia (Berry, 1975), Tioman Island, Singapore (Lim and Lim, 1992), Sumatra, Bintan, all parts of Borneo and the Natuna Islands (Inger and Stuebing, 2005; Mistar, 2003). Figure 22. M. nasuta from Tapan (Photograph by J. Holden). Megophrys paralella Megophrys paralella was described by Inger and Iskandar (2005). Type locality of the species is Lubuk Selasih, West Sumatra, at elevation 1289 meters asl. -

PETITION To: KEN SALAZAR, SECRETARY, US DEPARTMENT
PETITION To: KEN SALAZAR, SECRETARY, U.S. DEPARTMENT OF THE INTERIOR Petition: To List All Live Amphibians in Trade as Injurious Unless Free of Batrachochytrium dendrobatidis Submitted by: Defenders of Wildlife, 1130 17th Street NW, Washington, DC 20036 Date: September 9, 2009 Executive Summary and Text of Proposed Amendment: Robust measures to conserve Earth’s amphibians are urgently needed. The absence of Federal protective measures applied to the import, interstate commerce and export of live amphibians has led to excessive risk that the globally devastating Batrachochytrium dendrobatidis (“Bd”) pathogen, which causes the deadly disease chytridiomycosis, will continue to enter, spread within and be shipped out of the United States. This shockingly unregulated trade - primarily for pet use and as live animals for consumption as frog legs - continues to threaten the survival of multiple amphibians, including, but not limited to, U.S. and foreign species listed by the U.S. Fish and Wildlife Service (FWS) under the Endangered Species Act (ESA), candidate species and other species as well. All Federal agencies have affirmative duties to protect these species. However, the only Federal regulation on the amphibian trade, 50 CFR §16.14, now allows “all species” of amphibians to be “imported, transported and possessed” without restriction. This FWS regulation is far too liberal and should be amended to require health certification and handling based on a consensus international standard, adopted by the World Organization for Animal Health (OIE), which the United States voted to support at the May 2008 annual meeting of the parties.. The U.S. vote in support of the OIE standard came from the U.S. -
