Read one of the latest reports from field researchers participating in Conservation International's Search for the Lost Frogs Champaign.
25 August 2010
The tiny frog (known adults between 10.6 and 12.8 mm; about the size of a pea) was discovered by Dr. Indraneil Das and Dr. Alexander Haas in the forests of the Matang Range, Sarawak, Malaysian Borneo. the description appeared this month in the journal Zootaxa. Dr. Indraneil Das is leading a team within the Lost Frogs Campaing, of Conservation International.
The frog lives in close association with a pitcher plant (Nepenthes ampullaria) from which the species takes the name (Microhyla nepenthicola). The larvae of this frog develop inside these plants, after the frogs deposit the eggs on the sides of the pitcher.
As in similar situations around the tropics, scientists who saw specimens of this frog in the past thought they were juveniles of another species.

Conservation International is supporting expeditions to search some amphibian species that haven’t been seen for more than a decade. Scientists are optimistic about the prospect of at least one rediscovery during this campaing.
The search is taking place in 18 countries accross Latin America, Africa and Asia, and it is
the first ever coordinated effort to find such a large number of "lost"
frogs. There is a list of the "top 10" species of the 100 being searched believed to be particularly exciting to find. The top 10 are: the golden toad (Incilius periglenes), the gastric broofing frog (Rhebatrachus vitellinus), the Mesopotamia beaked toad (Rhinella rostrata), the Jackson´s climbing salander (Bolitoglossa jacksoni), the African painted frog (Callixalus pictus), the Río Pescado Stubfoot toad (Atelopus balios), the scarlet frog (Atelopus sorianoi; depicted here), the Hula painted frog (Discoglossus nigriventer), the Sambas stream toad (Ansonia latidisca), and the Turkestanian salamander (Hynobius turkestanicus).

In spite of their large sizes, new species of monitor lizards (genus Varanus) are still being discovered, which speaks of our poor understanding of biodivertity on Earth.
Two new species (V. rasmusseni and V. palawenensis) and a new subspecies (V. c. cumingi) of monitor lizards were recently described from the Philippines in an article published in Zootaxa.

Today’s “species of the day” is a curious amphibian found in Chile and neighboring Argentina, with a peculiar triangular shape of its head and a cylindrical dermal appendage at the tip of the snout. Most remarkable is its strange reproductive strategy of brooding egg and larvae within its mouth, from where the newly metamorphosed froglets step out.
Populations of this frog, discovered by Darwin in his famous travel around the World, are in decline, to the point that it is now considered in the conservation category of “Vulnerable”. Most probably, the causes of the declines are related to human activities, of which deforestation and several factors associated with climate change are among the main culprits.

"The Ploughshare Tortoise, Astrochelys yniphora, is listed as ‘Critically Endangered’ on the IUCN Red List of Threatened SpeciesTM due to a declining wild population of a few hundred animals. The elongated front spike of the undershell, used by males in breeding jousts for females, is the most remarkable feature of this spectacular tortoise.
Restricted to a tiny area of dry scrubland in northwestern Madagascar, this species has received conservation attention since the early 1970s. Protection of the small population in its natural habitat and a captive breeding programme slowly began to increase its numbers, until it became a target of illegal international wildlife traders.
Though strictly protected under Malagasy and CITES laws, unacceptable numbers of animals are smuggled and sold for huge sums by criminal pet dealers. Enhanced conservation measures are urgently needed to save this species, notably enforcing legal protection to prosecute those who drive the illegal trade, and repatriating recovered animals to secure breeding programmes".

A proposal was recently made public by the U.S. Fish and Wildlife Service and NOAA Fisheries Service to change conservation status of American Northwest Atlantic populations of loggerhead turtles (Caretta caretta) to be treated as Endangered.
Florida accounts for over 90% of loggerhead nesting in the United States. Regrettably, nesting throughout this State has declined by over 40% since1998. The greatest threat to its survival today seems to be accidental capture, injury and death in commercial fisheries.
Concern about the species was triggered during the most recent chilling event in Florida, when almost all of the turtles rescued from the cold waters were green turtles –as opposed to previous cold events, when loggerheads accounted for about half of the captures. These findings raise concern that juvenile loggerheads, as well as nesting adults, could be in decline.
Strong conservation actions need to be taken on other critical populations along the Caribbean. Populations of Caretta caretta almost disappeared from historical nesting sites in Eastern Venezuela that, according to marine turtle conservation leader Hedelvy Guada, have suffered a drastic decline in recent times. Although currently listed as “Endandered” in Venezuela, similar to the category granted by the IUCN on global terms, Guada, based on the country local nesting crashes of this species (locally known as “tortuga cabezona”, “Caguama” or Carey”) have proposed to change its conservation status to Critically Endangered. Colombian populations have, also, diminished drastically. Nesting sites in other Caribbean places are scarce, although important colonies are present in Mexico. The largest numbers of nesting sites occur in the later, as well as along the Southeast coast of the United States, and some coasts of Brazil.

Colombia is the most frog diverse country in the World. Originally believed not to have as many endangered amphibians as the neighboring Andean countries of Ecuador and Venezuela, recent studies have demonstrated that, as in these other countries, an important part of its amphibian fauna is at some kind of risk. An example of a Colombian anuran amphibian in peril is a giant species of glass frog, Centrolene ballux (common name: Burrowes’ Giant Glass Frog), which is listed as ‘Critically Endangered’ on the IUCN Red List of Threatened Species.

The “Titicaca water frog” (“Rana gigante del Lago Titicaca”, Telmatobius culeus) is the World’s largest aquatic anuran amphibian.
There are reports of specimens up to 50 cm in length and weighting 1 kilogram. It is a completely aquatic species, bearing many skins folds thought to help in breathing through increased area for respiration.
It is a species endemic to Lago Titicaca, the World’s largest (204 x 65 km) and highest (3800 m) endorheic lake (that is, in a closed internal drainage basin) shared by Bolivia and Peru.
Although currently listed as “Critically Endangered” and with its habitat being protected, specimens of this unique frog are still sold for human consumption in restaurants at Lake Titicaca, and also as souvenirs or as byproducts used in traditional medicine.

One of the most endangered crocodilians, the Chinese alligator (Alligator sinesis) is also one of the smallest (about 2 m long). This relative of the American alligator (Alligator mississippiensis) has a geographic distribution restricted to the lower Yangtze River region in China. Habitat destruction by human pressure for agriculture has been considered the major cause of the species’ decline. It is listed as “Critically Endangered” since it has suffered a drastic decline in numbers of wild individuals (estimated to be less than 150) and the extant populations hold less than 10 individuals each. However, about 10,000 specimens are currently being reared in captivity and are a source of hope for the long-term survival of the species through reintroductions in the wild.
