Low Incubation Temperatures Negatively Influence Locomotor Performance and Behavior of the Nocturnal Lizard Oligosoma suteri (Lacertidae: Scincidae)

Mar 21, 2008; Hare, Kelly M; Pledger, Shirley; Daugherty, Charles H ... We investigated the effects of artificial incubation regimes, experimental temperature, and age on the locomotor performance of New Zealand's only endemic oviparous lizard, Oligosoma suteri. Artificial incubation is often used to produce founders of new populations of endangered reptiles and can ...

Sexual Dimorphism in the Three-toed Amphiuma, Amphiuma tridactylum: Sexual Selection or Ecological Causes?

Mar 21, 2008; Fontenot, Clifford L Jr; Seigel, Richard A ... Sexual dimorphism is widespread among vertebrates, and may be attributable to sexual selection, differences in ecology between the sexes, or both. The large aquatic salamander, Amphiuma tridactylum, has been suggested to have male biased sexual dimorphism that is attributable to male-male ...

Strategic Male Calling Behavior in an Australian Terrestrial Toadlet (Pseudophryne bibronii)

Mar 21, 2008; Byrne, Phillip Gregory ... In animals that display acoustically, males may use the presence of conspecifics to choose optimal times for display, and in doing so minimize costs of advertisement while maximizing the probability of mating success. Among anuran amphibians, it is well known that males can adjust their calling ...

Spatiotemporal Population Trends of Notropis simus pecosensis in Relation to Habitat Conditions and the Annual Flow Regime of the Pecos River, 1992-2005

Mar 21, 2008; Hoagstrom, Christopher W; Brooks, James E; Davenport, Stephen R ... The threatened Pecos Bluntnose Shiner, Notropis simus pecosensis, is restricted to a 333-km segment of the Pecos River, New Mexico. This is a relatively long, undammed segment, but the flow regime is highly modified and the river channel is degraded. Within the occupied segment, upstream river ...

A New Species of Catfish Genus Chrysichthys from Lake Tanganyika (Siluriformes: Claroteidae)

Mar 21, 2008; Hardman, Michael ... During the examination of Lake Tanganyikan fishes held at the American Museum of Natural History, several specimens of the genus Chrysichthys could not be identified to any of the known species from the lake or elsewhere. This material is believed to represent a new species, distinguished from ...

Experimental Test of Spawning Site Selection by Buergeria japonica (Anura: Rhacophoridae) in Response to Salinity Level

Mar 21, 2008; Haramura, Takashi ... Spawning site selection can strongly influence egg survival and the distribution patterns of species. Coastal areas are risky environments for breeding amphibians because the rate of egg survival falls drastically with increased salinity. The working hypothesis of the present study was that ...

Necrotic Egg and Hatchling Remains Are Key Factors Attracting Dipterans to Sea Turtle (Caretta caretta, Chelonia mydas, Natator depressus) Nests in Central Queensland, Australia

Mar 21, 2008; Hall, S C B; Parmenter, C J ... Although infestation of turtle nests by dipteran larvae is known to occur in both freshwater and marine species around the globe, the role of insects in turtle nests remains unclear in this relatively understudied phenomenon. The present study was part of a larger effort to elucidate the role of ...

A New Pelvicless Killifish Species of the Genus Rivulus, Subgenus Melanorivulus (Cyprinodontiformes: Rivulidae), from the Upper Tocantins River Basin, Central Brazil

Mar 21, 2008; Costa, Wilson J E M; Brasil, Gilberto C ... Rivulus planaltinus, new species, from the Maranhão River drainage, upper Tocantins River basin, central Brazil, is described. It is a member of a subclade of the subgenus Melanorivulus endemic to the central Brazilian plateau, which is diagnosed by having ventral process of angulo-articular ...

Reproductive Output Depends on Body Condition in Spotted Turtles (Clemmys guttata)

Mar 21, 2008; Litzgus, Jacqueline D; Bolton, Frances; Schulte-Hostedde, Albrecht I ... The body condition of an animal reflects its energetic state such that an animal in good condition has greater energy reserves than one that is in poor condition. Body condition in turn should be positively correlated with fitness because energetic reserves limit the amount of energy that can be ...

A New Species of Nanobagrus (Teleostei: Bagridae) from Southern Borneo

Mar 21, 2008; Ng, Heok Hee ... Nanobagrus immaculatus, a new species of bagrid catfish, is described from the Kahayan River drainage in southern Borneo. Nanobagrus immaculatus is most readily distinguished from congeners in having a uniformly dark-colored body lacking pale spots or patches (vs. pale spots or patches always ...

Role of Current Versus Historical Hydrology in Amphibian Species Turnover within Local Pond Communities

Mar 21, 2008; Church, Don R ... This study explored how historical and current hydrological conditions covaried with colonization and occupancy probabilities for 14 pond-breeding amphibians at 32 natural sinkhole ponds over a five-year period. Occupancy and colonization were estimated independently for breeding adults and ...

Body Size, Growth, and Reproduction in a Population of Western Cottonmouths (Agkistrodon piscivorus leucostoma) in the Ozark Mountains of Northwest Arkansas

Mar 21, 2008; Hill, Jacques G III; Beaupre, Steven J ... Life histories of a species often vary geographically, and comparative studies of populations in different habitats are useful for understanding how environmental variation influences life history. Such studies are currently lacking for most snake species despite their growing importance as ...

Dry-season Breeding of a Characin in a Neotropical Mountain River

Mar 21, 2008; Torres-Mejia, Mauricio; Ramírez-Pinilla, Martha P ... The annual reproductive cycle of Creagrutus guanes (Teleostei, Characidae) was studied in a tropical mountain river, a type of habitat where reproductive biology of fishes has been scarcely investigated. Analysis was made on adults, 70 males and 135 females, which were captured in 13 monthly ...

Experimental Evidence that Amphibian Ranaviruses are Multi-Host Pathogens

Mar 21, 2008; Schock, Danna M; Bollinger, Trent K; Chinchar, V Gregory; Jancovich, James K; Collins, James P ... Infectious diseases, including those caused by ranaviruses (family Iridoviridae), are among the suspected causes of global amphibian declines. Like many pathogens, ranaviruses appear to infect multiple species. We examined several North American amphibian ranavirus isolates to improve our ...

A Test for a Trade-Off in Salinity Tolerance in Early Life-History Stages in Lucania goodei and L. parva

Mar 21, 2008; Fuller, Rebecca C ... Lucania goodei and L. parva are close phylogenetic relatives that differ in abundance along a salinity gradient where L. goodei is found predominantly in freshwater sites, and L. parva is found most often in brackish water sites. It has been suggested that these taxa diverged along a salinity ...
