This book was released on 2019 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract "Within the scorpion genus Vaejovis C.L. Koch, the “mexicanus” group is composed of species distributed in the mountains of México. This group presents taxonomic problems, because its characterization and the species included in the group have varied through the years. In the present work, we redefine this group based on several morphological characters, and we differentiate it from the other two species groups within the genus: “vorhiesi” and “nit dulus+nigrescens”. Additionally, five new species are described: Vaejovis ceboruco sp. nov., Vaejovis nanchititla sp. nov., Vaejovis santibagnezi sp. nov., Vaejovis talpa sp. nov. and Vaejovis tapalpa sp. nov; the males of three species are described for the first time (V. dugesi, V. nigrofemoratus and V. tesselatus); and the updated diagnosis for all species is included. Keys for the identification of males and females of the 30 species included in. Keywords: group characterization, species diagnoses, new species, dichotomous keys, Myriapoda"--Page 3.

Download or read book Arthropod Biology and Evolution written by Alessandro Minelli and published by Springer Science & Business Media. This book was released on 2013-04-11 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than two thirds of all living organisms described to date belong to the phylum Arthropoda. But their diversity, as measured in terms of species number, is also accompanied by an amazing disparity in terms of body form, developmental processes, and adaptations to every inhabitable place on Earth, from the deepest marine abysses to the earth surface and the air. The Arthropoda also include one of the most fashionable and extensively studied of all model organisms, the fruit-fly, whose name is not only linked forever to Mendelian and population genetics, but has more recently come back to centre stage as one of the most important and more extensively investigated models in developmental genetics. This approach has completely changed our appreciation of some of the most characteristic traits of arthropods as are the origin and evolution of segments, their regional and individual specialization, and the origin and evolution of the appendages. At approximately the same time as developmental genetics was eventually turning into the major agent in the birth of evolutionary developmental biology (evo-devo), molecular phylogenetics was challenging the traditional views on arthropod phylogeny, including the relationships among the four major groups: insects, crustaceans, myriapods, and chelicerates. In the meantime, palaeontology was revealing an amazing number of extinct forms that on the one side have contributed to a radical revisitation of arthropod phylogeny, but on the other have provided evidence of a previously unexpected disparity of arthropod and arthropod-like forms that often challenge a clear-cut delimitation of the phylum.

This book was released on 2005-08-25 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the biodiversity and biogeography of nothern Mexico, documents the biological importance of regional ecosystems and the impacts of human land use on the conservation status of plants and wildlife. It should become the standard source document for the conservation status of species and ecosystems in this region, which is of unusual biological interest because of its high biodiversity and highly varied landscape and biological zonation.

Available in PDF, EPUB and Kindle. Book excerpt: Spiders are among the most diverse groups of terrestrial invertebrates, yet they are among the least studied and understood. This first comprehensive guide to all 68 spider families in North America beautifully illustrates 469 of the most commonly encountered species. Group keys enable identification by web type and other observable details, and species descriptions include identification tips, typical habitat, geographic distribution, and behavioral notes. A concise illustrated introduction to spider biology and anatomy explains spider relationships. This book is a critical resource for curious naturalists who want to understand this ubiquitous and ecologically critical component of our biosphere.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two new species of the mexicanus group of Vaejovis C.L. Koch are described from the Madrean pine-oak forests of the Sierra Madre Occidental in the state of Durango, Mexico. These species, Vaejovis sierrae sp. nov. and Vaejovis mcwesti sp. nov., are distinguished from each other and the only other species of the mexicanus group known from this mountain range, Vaejovis montanus Graham and Bryson, by morphometrics, carinal development of the pedipalps, granulation of the metasoma, and body size. A key to the species of the mexicanus group from the Sierra Madre Occidental is provided.

Download or read book Drosophilidae Diptera written by Irina Brake and published by BRILL. This book was released on 2013-01-21 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns about global biodiversity are rising dramatically, yet we are lagging behind in the most basic prerequisite for its understanding and conservation: the inventory. Insect species may make up five or ten times the number of all other plant and animal species combined, and as such they represent one of the major challenges in biosystematic science. World Catalogue of Insects is an initiative aiming at compiling worldscale, authoritative catalogues of monophyletic insect taxa. Volumes in this series contain standard nomenclatoral information on all names pertaining to the taxon treated, including type locality and distribution to the extent this is relevant. Additional information is optional, e.g., location, status and condition of types; biology; bibliographical information; pest status; vector status; etc. This volume nine focuses on Drosophilidae (Diptera).

Download or read book Scorpion Venoms written by P. Gopalakrishnakone and published by Springer. This book was released on 2021-01-14 with total page 550 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.
