Amphibian Abundance and Detection Trends During a Large Flood in a Semi-Arid Floodplain Wetland
Herpetological Conservation and Biology 11:408–425. Submitted: 26 January 2016; Accepted: 2 September 2016; Published: 16 December 2016. Amphibian Abundance and Detection Trends During a Large Flood in a Semi-Arid Floodplain Wetland Joanne F. Ocock1,4, Richard T. Kingsford1, Trent D. Penman2, and Jodi J.L.

We assessed frog diversity in the Macquarie Marshes, a semi-arid floodplain wetland of conserva- tion significance, identifying environmental variables that might explain abundances and detection of species. We collected relative abundance data of 15 amphibian species at 30 sites over four months, coinciding with a large natural flood. We observed an average of 39.9 ± (SE) 4.3 (range, 0-246) individuals per site survey, over 47 survey nights. Three non-burrowing, ground-dwelling species were most abundant at temporarily flooded sites with low- growing aquatic vegetation (e.g., Limnodynastes tasmaniensis, Limnodynastes fletcheri, Crinia parinsignifera). Most arboreal species (e.g., Litoria caerulea) were more abundant in wooded habitat, regardless of water permanency. -

In this review, we focus on the effects of human disturbance on terrestrial apex predators. We summarize their ecological role in nature and how they respond to different sources of human disturbance. Apex predators control their prey and smaller predators numerically and via behavioral changes to avoid predation risk, which in turn can affect lower trophic levels. Crucially, reducing population numbers and triggering behavioral responses are also the effects that human disturbance causes to apex predators, which may in turn influence their ecological role. Some populations continue to be at the brink of extinction, but others are partially recovering former ranges, via natural recolonization and through reintroductions. -
Dietary Specialization and Variation in Two Mammalian Myrmecophages (Variation in Mammalian Myrmecophagy)
Revista Chilena de Historia Natural 59: 201-208, 1986 Dietary specialization and variation in two mammalian myrmecophages (variation in mammalian myrmecophagy) Especializaci6n dietaria y variaci6n en dos mamiferos mirmec6fagos (variaci6n en la mirmecofagia de mamiferos) KENT H. REDFORD Center for Latin American Studies, Grinter Hall, University of Florida, Gainesville, Florida 32611, USA ABSTRACT This paper compares dietary variation in an opportunistic myrmecophage, Dasypus novemcinctus, and an obligate myrmecophage, Myrmecophaga tridactyla. The diet of the common long-nosed armadillo, D. novemcintus, consists of a broad range of invertebrate as well as vertebrates and plant material. In the United States, ants and termites are less important as a food source than they are in South America. The diet of the giant anteater. M. tridactyla, consists almost entirely of ants and termites. In some areas giant anteaters consume more ants whereas in others termites are a larger part of their diet. Much of the variation in the diet of these two myrmecophages can be explained by geographical and ecological variation in the abundance of prey. However, some variation may be due to individual differences as well. Key words: Dasypus novemcinctus, Myrmecophaga tridactyla, Tamandua, food habits. armadillo, giant anteater, ants, termites. RESUMEN En este trabajo se compara la variacion dietaria entre un mirmecofago oportunista, Dasypus novemcinctus, y uno obligado, Myrmecophaga tridactyla. La dieta del armadillo comun, D. novemcinctus, incluye un amplio rango de in- vertebrados así como vertebrados y materia vegetal. En los Estados Unidos, hormigas y termites son menos importantes como recurso alimenticio de los armadillos, de lo que son en Sudamérica. La dieta del hormiguero gigante, M tridactyla, está compuesta casi enteramente por hormigas y termites. -

Petition to List the Relict Leopard Frog (Rana Onca) As an Endangered Species Under the Endangered Species Act
BEFORE THE SECRETARY OF INTERIOR PETITION TO LIST THE RELICT LEOPARD FROG (RANA ONCA) AS AN ENDANGERED SPECIES UNDER THE ENDANGERED SPECIES ACT CENTER FOR BIOLOGICAL DIVERSITY SOUTHERN UTAH WILDERNESS ALLIANCE PETITIONERS May 8, 2002 EXECUTIVE SUMMARY The relict leopard frog (Rana onca) has the dubious distinction of being one of the first North American amphibians thought to have become extinct. Although known to have inhabited at least 64 separate locations, the last historical collections of the species were in the 1950s and this frog was only recently rediscovered at 8 (of the original 64) locations in the early 1990s. This extremely endangered amphibian is now restricted to only 6 localities (a 91% reduction from the original 64 locations) in two disjunct areas within the Lake Mead National Recreation Area in Nevada. The relict leopard frog historically occurred in springs, seeps, and wetlands within the Virgin, Muddy, and Colorado River drainages, in Utah, Nevada, and Arizona. The Vegas Valley leopard frog, which once inhabited springs in the Las Vegas, Nevada area (and is probably now extinct), may eventually prove to be synonymous with R. onca. Relict leopard frogs were recently discovered in eight springs in the early 1990s near Lake Mead and along the Virgin River. The species has subsequently disappeared from two of these localities. Only about 500 to 1,000 adult frogs remain in the population and none of the extant locations are secure from anthropomorphic events, thus putting the species at an almost guaranteed risk of extinction. The relict leopard frog has likely been extirpated from Utah, Arizona, and from the Muddy River drainage in Nevada, and persists in only 9% of its known historical range. -
