This book was released on 2019 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: We review the systematics of the species of Gastrotheca (Anura: Hemiphractidae) in the highlands of the southern Ecuadorian Andes. We analyzed phylogenetic, morphological, ecological, and acoustic data from populations in the region. We provide an updated phylogenetic hypothesis inferred from a database that contains 42 species of Gastrotheca, and sequences from mitochondrial (12S, 16S, and ND1) and nuclear (POMC and RAG-1) genes. We describe four new endemic biphasic species for Ecuador (Gastrotheca cuencana, G. elicioi, G. turnerorum, and G. yacuri). In addition, we redefine G. lojana, recently resurrected from the synonymy of G. monticola, and redescribe G. litonedis. Furthermore, we describe the tadpoles and ontogenetic color changes in six species (G. cuencana, G. elicioi, G. litonedis, G. lojana, G. pseustes, and G. turnerorum). Also, we describe the calls of seven species (G. cuencana, G. elicioi, G. litonedis, G. lojana, G. pseustes, G. testudinea, and G. yacuri).

Download or read book The Cutting Edge written by Robert A. Fimbel and published by Columbia University Press. This book was released on 2001-12-19 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent decades have seen unprecedented growth in the scale and intensity of industrial forestry. Directly and indirectly, it has degraded the wildlife and ecological integrity of these tropical forests, prompting a need to evaluate the impact of current forest management practices and reconsider how best to preserve the integrity of the biosphere. Synthesizing the body of knowledge of leading scientists and professionals in tropical forest ecology and management, this book's thirty chapters examine in detail the interplay between timber harvesting and wildlife, from hunted and protected habitats to invertebrates and large mammal species. Collectively, the contributors suggest that better management is pivotal to the maintenance of the tropics' valuable biodiversity, arguing that we must realize that tropical forests harbor the majority (perhaps 70 to 80 percent) of the world's animal species. Further, they suggest modifications to existing practices that can ensure a better future for our valuable resources.

Book Synopsis Evolution in the Genus Rhinella by : Martín O. Pereyra
Download or read book Evolution in the Genus Rhinella written by Martín O. Pereyra and published by . This book was released on 2021 with total page 155 pages. Available in PDF, EPUB and Kindle. Book excerpt: True toads of the genus Rhinella are among the most common and diverse group of Neotropical anurans. These toads are widely distributed throughout South America, inhabiting a great diversity of environments and ecoregions. Currently, however, the genus is defined solely on the basis of molecular characters, and it lacks a proper diagnosis. Although some phenetic species groups have traditionally been recognized within Rhinella, the monophyly of some of them have been rejected in previous phylogenetic analyses, and many species remain unassigned to these poorly defined groups. Additionally, the identity and taxonomy of several species are problematic and hinder the specific recognition and description of undescribed taxa. In this work, we first perform phylogenetic analyses of separate mitochondrial and nuclear datasets to test the possible occurrence of hybridization and/or genetic introgression in the genus. The comparative analysis of both datasets revealed unidirectional mitochondrial introgressions of an unknown parental species into R. horribilis ("ghost introgression") and of R. dorbignyi into R. bernardoi; therefore, the mitochondrial and nuclear datasets of these species were considered separately in subsequent analyses. We performed total-evidence phylogenetic analyses that included revised molecular (four mitochondrial and five nuclear genes) and phenotypic (90 characters) datasets for 83 nominal species of Rhinella, plus several undescribed and problematic species and multiple outgroups. Results demonstrate that Rhinella was nonmonophyletic due to the position of R. ceratophrys, which was recovered as the sister taxon of Rhaebo nasicus with strong support. Among our outgroups, the strongly supported Anaxyrus + Incilius is the sister clade of all other species of Rhinella. Once R. ceratophrys is excluded, the genus Rhinella is monophyletic, well supported, and composed of two major clades. One of these is moderately supported and includes species of the former R. spinulosa Group (including R. gallardoi); the monophyletic R. granulosa, R. crucifer, and R. marina Groups; and a clade composed of the mitochondrial sequences of R. horribilis. The other major clade is strongly supported and composed of all the species from the non-monophyletic R. veraguensis and R. margaritifera Groups, the former R. acrolopha Group, and R. sternosignata. Consistent with these results, we define eight species groups of Rhinella that are mostly diagnosed by phenotypic synapomorphies in addition to a combination of morphological character states. Rhinella sternosignata is the only species that remains unassigned to any group. We also synonymize nine species, treat three former subspecies as full species, and suggest that 15 lineages represent putative undescribed species. Lastly, we discuss the apparently frequent occurrence of hybridization, deep mitochondrial divergence, and "ghost introgression"; the incomplete phenotypic evidence (including putative character systems that could be used for future phylogenetic analyses); and the validity of the known fossil record of Rhinella as a source of calibration points for divergence dating analyses.
Book Synopsis The Conservation and Biogeography of Amphibians in the Caribbean by : Neftalí Ríos-López
Download or read book The Conservation and Biogeography of Amphibians in the Caribbean written by Neftalí Ríos-López and published by Pelagic Publishing Ltd. This book was released on 2023-02-28 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: An expansive and detailed review of the biology of Caribbean amphibians, considering their threats, conservation and outlook in a changing world. Amphibians are the group of vertebrates undergoing the fastest rate of extinction; it is urgent that we understand the causes of this and find means of protecting them. This landmark illustrated volume brings together the leading experts in the field. As well as offering an overview of the region as a whole, individual chapters are devoted to each island or island-group and the measures used to protect their amphibians through legislation or nature reserves. The biological background of insular biogeography, including its methods, analysis and results, is reviewed and applied specifically to the problems of Caribbean amphibians – this includes a re-examination of patterns and general ideas about the status of amphibians in the Anthropocene. The Conservation and Biogeography of Amphibians in the Caribbean offers an important baseline against which future amphibian conservation can be measured in the face of climate change, rising sea level and a burgeoning human population. Covers over 300 species.
