Abstract

Adenomera simonstuarti is a poorly known species complex inhabiting western Amazonia. Here we reevaluate the species diversity within this complex based on previously documented and newly acquired molecular and phenotypic data. We also redescribe the calling pattern of the nominal species based on the original recording (Peru) and a new recording (Brazil). Our results indicate eight geographically structured genetic lineages and the nominal species with a multi-note call pattern. This is the first association of calls and DNA sequence from a voucher specimen, thereby enabling the assignment of A. simonstuarti to one specific lineage within the complex. The multi-note call was not previously reported and represents an important additional diagnostic character within Adenomera. The geographic distribution of A. simonstuarti is substantially narrowed down to the southwestern portion of the entire geographic range recognized for the complex. The lack of taxonomic resolution in the complex is a major conservation concern by preventing us from evaluating the potential threats and extinction risks of each of the lineages. Future research should follow the protocol of combining calls and DNA sequences associated with voucher specimens as a means to address the taxonomic status of genetic lineages within the A. simonstuarti complex.

11. A reassessment of the extinction risk of the Critically Endangered Oxapampa poison frog Ameerega planipaleae (Dendrobatidae).

Abstract

Assessments of extinction risk are required to inform conservation action, but the usefulness of assessments is undermined if they are not current. Ameerega planipaleae , a poison frog endemic to the cloud forests of central Peru, was last assessed in 2004. We therefore sought to provide updated data to inform the reassessment of this species. Based on our findings, we recommend that this frog remain categorized as Critically Endangered, but under modified criteria, and that conservation actions are taken to reduce the pressures of local threats, especially the overuse of agrochemicals.

14. Cryptic species complexes, widespread species and conservation: lessons from Amazonian frogs of the Leptodactylus marmoratus group (Anura: Leptodactylidae).

Abstract

Morphologically cryptic species act as a wild card when it comes to biodiversity assessments and conservation, with the capacity to dramatically alter our understanding of the biological landscape at the taxonomic, ecological, biogeographic, evolutionary, and conservation levels. We discuss the potential effects that cryptic species may have on biodiversity assessments and conservation, as well as some of the current issues involving the treatment of cryptic species both at taxonomic and conservation levels. In addition, using a combination of advertisement call and morphological data, we describe a new species of the Leptodactylus marmoratus group from the upper Amazon basin, and we assess how cryptic species can affect conservation assessments of species in the Leptodactylus marmoratus group by examining how recent findings affect our understanding of the distribution of what is assumed to be a widespread Amazonian species, Leptodactylus andreae.

Abstract

The gecko Phyllodactylus sentosus has been registered only in few archeological sites in Lima city, from where it is endemic, and is considered a species in critical danger, with scarce knowledge of its distribution and conservation status. In the present publication we present 4 new records for this species, all of them within the city of Lima, Peru. [ABSTRACT FROM AUTHOR]
