Anura; integument; new species; nose; tadpoles
Abstract:
... Proceratophrys dibernardoi is a newly described species belonging to the Proceratophrys cristiceps group. Herein, we describe the external morphology of tadpoles of P. dibernardoi. Although external larval morphology of P. cristiceps group members is quite similar, the tadpole of P. dibernardoi may be distinguished by a combination of morphological traits, such as body shape that is elliptical in ...

Subject:
Anura; ecology; frogs; genetics; larvae; life history; natural history; phylogeny; reproduction
Abstract:
... Although most of the unique ways that frogs reproduce were described in the 1800s and 1900s, additional modes are still being discovered in the 21st Century. The concept of reproductive mode has evolved from descriptive natural history to an integration of developmental biology, genetics, systematics, evolution, ecology, behavior, and physiology that frames our thinking about the transition of ver ...

Abstract:
... We studied Desert Massasauga Rattlesnakes (Sistrurus catenatus edwardsii) in southeastern Colorado in 1998 and 2005–2007. Mark–recapture data for 770 snakes indicated a population size of >3,500 snakes in an area of approximately 4,800 ha. Field growth rates and size class frequency distributions showed that average snake age was 3 yr; 4 yr old snakes were frequently encountered, but less than 4% ...

Abstract:
... Habitat size and heterogeneity are among the main factors determining local species richness. However, distinguishing between them is critical to discriminate stochastic from the habitat-driven processes underlying local patterns of species distribution. Here, we test the individual effects and interaction of habitat size and heterogeneity in driving the occurrence of species in water bodies in th ...

Abstract:
... Currently there is limited information on the population dynamics of tadpoles, particularly in the Neotropical region. Because of this dearth of information, studies on the temporal distribution of different tadpole developmental stages are important for understanding the dynamics of these organisms in their aquatic environment. We studied the temporal distribution of the Torrent Frog Hylodes uai ...

The new species is described from forest and lacustrine habitats of the Albertine Rift of Central Africa, is superficially similar to topotypic L. modestus from Cameroon, but it is distinguished by advertisement call, morphology, and sequences of 16S, cyt b, and RAG1. The new species is yet another amphibian that occurs in the I ...

Abstract:
... Can the loss of forest habitat cause changes in local communities? The results of our study of anuran assemblages in the southern Amazon indicate that the conversion of forest into open environments results in the substitution of species and the reduction of beta diversity. The increasing loss of tropical forests to agricultural development, especially in the Amazon, has resulted in the extensive ...
