These include complex effects of multiple abiotic and biotic stressors that may drive population losses. These losses are especially illustrated by amphibians, whose populations are declining worldwide. The causes of amphibian population declines are multifaceted and context-dependent. One major factor affecting amphibian populations is emerging infectious disease. Several pathogens and their associated diseases are especially significant contributors to amphibian population declines. -

E-mail: [email protected] The systematics of the dart-poison frogs, family Dendrobatidae, experienced several taxonomic rearrangements over time (e.g., Grant et al. 2006, 2017; Brown et al. 2011). Currently, this family comprises 194 described species organized in three sub-families and 15 genera (Frost 2018). Among them, the genus Adelphobates Grant, Frost, Caldwell, Gagliardo, Haddad, Kok, Means, Noonan, Schargel, & Wheeler, 2006, comprises three species, all distributed in Central and lower Amazon drainage of Peru and Brazil, and possibly in northeast of Bolivia (Grant et al. 2006; Frost 2018). Adelphobates galactonotus (Steindachner 1864) is an endemic Brazilian frog, and can be found throughout Pará, Maranhão, Mato Grosso and Tocantins states (Hoogmoed & Avila-Pires 2012), related to Amazon forest formations and also in transitional areas between the Cerrado and the Amazon forest (Valdujo et al. -

We compared species lists from nine sites in the Madre de Dios region, five of which are in nationally recognized protected areas and four are outside the country’s protected area system. Los Amigos, occurring outside the protected area system, is the most species-rich locality included in our comparison. -

While the reproductive strategies of Leiuperinae are known, few studies have been conducted regarding the reproductive behaviour that underlies them. The aim of this study was to document the structural characteristics of nesting microsites, to describe the process of foam nest construction, and to explore the presence of male agonistic and chorus behaviour in Pleurodema tucumanum. Nests were found close to the edge of a temporary pond and the mean temperature of the foam nests was always close to the mean temperature of the pond water. -

This species inhabits rainforest on granitic substrate on the northwestern edge of the Guiana Shield (Estado Amazonas, Venezuela). The new species is distinguished from congeners by sexual dimorphism, its unique male color pattern (including two bright orange parotoid marks and two orange paracloacal spots on dark brown background), call characteristics and other morphological features. Though to the new species is known only from the northwestern edge of the Guiana Shield, its distribution may be more extensive, as there are no significant biogeographic barriers isolating the type locality from the granitic lowlands of Venezuela.

A Review of Chemical Defense in Poison Frogs (Dendrobatidae): Ecology, Pharmacokinetics, and Autoresistance
Chapter 21 A Review of Chemical Defense in Poison Frogs (Dendrobatidae): Ecology, Pharmacokinetics, and Autoresistance Juan C. Santos , Rebecca D. Tarvin , and Lauren A. O’Connell 21.1 Introduction Chemical defense has evolved multiple times in nearly every major group of life, from snakes and insects to bacteria and plants (Mebs 2002 ). However, among land vertebrates, chemical defenses are restricted to a few monophyletic groups (i.e., clades). Most of these are amphibians and snakes, but a few rare origins (e.g., Pitohui birds) have stimulated research on acquired chemical defenses (Dumbacher et al. 1992 ). Selective pressures that lead to defense are usually associated with an organ- ism’s limited ability to escape predation or conspicuous behaviors and phenotypes that increase detectability by predators (e.g., diurnality or mating calls) (Speed and Ruxton 2005 ). Defended organisms frequently evolve warning signals to advertise their defense, a phenomenon known as aposematism (Mappes et al. 2005 ). Warning signals such as conspicuous coloration unambiguously inform predators that there will be a substantial cost if they proceed with attack or consumption of the defended prey (Mappes et al. 2005 ). However, aposematism is likely more complex than the simple pairing of signal and defense, encompassing a series of traits (i.e., the apose- matic syndrome) that alter morphology, physiology, and behavior (Mappes and J.

INTRODUCTION Until 1985, when Darrel Frost published the Catalogue of the Amphibians Species of de World, no comprehensive list of amphibians of Peru existed. Now, Rodriguez et al . (1993) have plublished a preliminary list of Amphibians from Peru with species distribution in ecological regions. Herein, I list all the species of amphibians reported from Peru and annotations on some species listed for Rodriguez et al . (op. cit.). The present list contains the following (family/genus/species): in Gymnophiona: 5/6/16, in Caudata: 1/1/3, and in Anura: 9/44/298, the total is 15/51/316.
