Beastly Bondage: The Costs of Amplexus in Cane Toads (Bufo marinus)
Feb 23, 2009; ... Reproductive activities can impose fitness costs as well as benefits. In most anuran species, males clasp females for prolonged periods prior to gamete release, and intuition suggests that the male's presence may impair the female's ability to move about and to feed. We tested the prediction ...

New Anatomical Analyses Suggest a Pumping Mechanism for the Vomeronasal Organ in Anurans
Feb 23, 2009; ... Based on histological cross-sections of the frog Phrynohyas resinifictrix, we present evidence suggesting the presence of a pumping mechanism associated with the function of the vomeronasal organ. We also propose that the fluid supply for the mechanism originates from gland secretions, which may ...
Effects of Streamflow and Intermittency on the Reproductive Success of Two Broadcast-spawning Cyprinid Fishes
Feb 23, 2009; ... We studied daily growth-increment formation in the otoliths of early life history stages of Sharpnose Shiner, Notropis oxyrhynchus, and Smalleye Shiner, Notropis buccula, in the Brazos River, Texas to investigate the influence of streamflow and intermittency on the production of young. Both ...
Reproductive and Trophic Ecology of an Assemblage of Aquatic and Semi-Aquatic Snakes in Tonle Sap, Cambodia
Feb 23, 2009; ... We studied the reproductive and trophic ecology of a group of aquatic and semi-aquatic snakes that face severe hunting pressure in Cambodia. Over a two-year period we sampled hunters' catches, measuring and dissecting a total of 8982 specimens of seven snake species, five of which belong to the ...

Feb 23, 2009; ... Baryancistrus beggini, new species, is described from the upper Río Orinoco and lower portions of its tributaries, the Río Guaviare in Colombia and Río Ventuari in Venezuela. Baryancistrus beggini is unique within Hypostominae in having a uniformly dark black to brown base color with a blue ...
Growth Patterns in Midas Cichlids Are Not Consistent with a Hypothesis of Socially Controlled Sex Determination
Feb 23, 2009; ... Social control of sex determination has been reported in juvenile Midas Cichlids, Amphilophus citrinellus, held in large captive groups. In adults, males are typically larger than females. Large body size relative to group-mates was proposed to cause male differentiation, and small body size ...
New Species of Cloud Forest Anolis (Squamata: Polychrotidae) in the crassulus Group from Parque Nacional Montaña de Yoro, Honduras
Feb 23, 2009; ... A new species of the Anolis crassulus group is described from the cloud forests of Parque Nacional Montaña de Yoro, Departamento de Francisco Morazán, Honduras. This species is distinguished from other members of the A. crassulus group by hemipenial morphology and characteristics of pholidosis ....
The Identity of Hylambates rufus aubryioides Andersson, 1907 (Anura: Arthroleptidae) from Cameroon
Feb 23, 2009; ... The taxonomic status of Hylambates rufus aubryioides Andersson, 1907, a taxon rarely treated in the literature and considered to represent a junior synonym of Leptopelis modestus, is re-evaluated. The taxon is redescribed and a lectotype is designated. Morphological comparisons revealed that it ...
Terrestrial Activity and Habitat Selection of Eastern Mud Turtles (Kinosternon subrubrum) in a Fragmented Landscape: Implications for Habitat Management of Golf Courses and Other Suburban Environments
Feb 23, 2009; ... In urbanized landscapes, golf course ponds may provide the only remaining habitat for semi-aquatic animals. Eastern Mud Turtles (Kinosternon subrubrum), which rely heavily on both aquatic and terrestrial habitats, may face challenges on golf courses, which typically have significantly modified ...
Effects of Sex and Microhabitat Use on Diel Body Temperature Variation in Midland Painted Turtles (Chrysemys picta marginata)
Feb 23, 2009; ... Sources of body temperature (T^sub b^) variation in freshwater turtles are known for very few species. Using surgically implanted, temperature-sensitive radiotransmitters in Midland Painted Turtles (Chrysemys picta marginata), we assessed T^sub b^ variation in relation to sex, microhabitat use, ...
Phylogeny of Gobioidei and Placement within Acanthomorpha, with a New Classification and Investigation of Diversification and Character Evolution
Feb 23, 2009; ... Phylogenies based on DNA sequence data are providing a range of new insights into relationships within Acanthomorpha, particularly in cases where morphological characters have been scanty or misleading. Molecular phylogenetic analyses of the perciform suborder Gobioidei have illuminated ...
Diel Movement and Predation Activity Patterns of the Eyelash Palm-Pitviper (Bothriechis schlegelii)
Feb 23, 2009; ... The Eyelash Palm-pitviper, Bothriechis schlegelii, is reported to be a nocturnal ambush predator that preys upon a wide variety of vertebrates. This study demonstrates that B. schlegelii has a greater temporal activity range than previously documented. Bothriechis schlegelii moves most ...
