Available in PDF, EPUB and Kindle. Book excerpt: This paper is the second monograph of nine that describes the global records of limno-terrestrial water bears (Tardigrada). Here, we provide a comprehensive list of non-marine tardigrades recorded from South America, providing an updated and revised taxonomy accompanied by geographic co-ordinates, habitat, and biogeographic comments. It is hoped this work will serve as a reference point and background for further zoogeographical and taxonomical studies.

Download or read book Water Bears The Biology of Tardigrades written by Ralph O. Schill and published by Springer. This book was released on 2019-02-14 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offering extensive information on tardigrades, this volume begins with a chapter on the history of tardigrades, from the first description by Goeze in 1773, until 1929, when the most comprehensive monographic approach by E. Marcus was published. Tardigrades’ organ systems, including their integument, body cavity, digestive, muscular, nervous and reproductive systems, as well as their overall external morphology, are summarized in the second chapter. Subsequent chapters present the current state of knowledge on tardigrade phylogeny, biogeography, paleontology, cytology and cytogenetics. In addition, the book provides insights into the ecology of tardigrades in marine, freshwater and terrestrial habitats. The reproduction, development and life cycles are summarized and the extraordinary environmental adaptations of encystment and cyclomorphosis, desiccation tolerance, freezing tolerance and radiation tolerance are discussed in detail. Further chapters provide an overview of key approaches in molecular tardigrade studies and describe techniques for sampling and sample processing. The book closes with a list of tardigrade taxa up to a sub-generic level, including the type species of each genus, the numbers of lower taxa in each taxon, and the main environments in which the taxa were found. Given its depth of coverage, the volume offers an invaluable resource for scientists from various disciplines who plan to research tardigrades, and for all others who are interested in these fascinating animals.

Download or read book The Armoured Marine Tardigrades Arthrotardigrada Tardigrada written by Jesper Guldberg Hansen and published by . This book was released on 2012 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last three decades several new species of the marine stygarctid tardigrades have accumulated in the tardigrade collection at the Natural History Museum of Denmark, University of Copenhageb. The major aims of the present investigation were to describe some of the new species, to further increase th knowledge of the morphological diversity and to conduct phylogenetic analyses of all currently described species within the marine family Stygarctidae. The major objectives of the phylogenetic analyses were to investigate the internal phylogentic relationships of Stygarctidae, their relationship to the most closely related previously recognized families (Neostygarctidae and Renaudarctidae), and the character evolution within the Stygarctidae. The outgroups were chosen to represent the extant members of presumed ancestral lineages of arthrotardigrade (Coronarctus, Coronarctidae and Neoarctus, Neoarctidae). In order to evaluate the significance of the morphological diversity within the Stygarctidae, all species currently described have been personally examined by the authors and species new to science were described in each of the genera: Faroestygarctus nov. gen, Mesotygaractus, Parastygarctus, Pseudostygarctus and Renaudarctus. The character matrix consists of 31 species and 81 morphological characters. The characters have been scored from six main characters systems, i.e. the arrangement of head lobes, the cuticular segmental plates, (head, body and caudal plates), the seminal receptacles, the legs and claws, the sense organs and the buccal apparatus. All 81 characters were parsimony informative and 51 are multistate characters. The most notable results from the phylogenetic analyses are: 1. Neostygarctus is the sister-group to the previously known genera in Stygarctinae and is included in this subfamily; 2. Faroestygarctus nov. gen. is the sister-group to the other genera in Stygarctinae; 3. Mesostygarctus is a valid taxon and is the sister-group to Pseudostygarctus; 4. Stygarctus spinifer is the sister-group to the other Stygaractus species and is not a member of Parastygarctus as recently suggested. In our opinion Megastygarctides is very different from the members of Stygarctinae and a position higher in the taxonomic hierarchy might be justified. Not surprisingly the Renaudarctidae is the sister-group to the Stygarctidae clade (Megastygarctidinae + Stygarctinae).

Download or read book The Great American Biotic Interchange written by Alberto Luis Cione and published by Springer. This book was released on 2015-04-24 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: South American ecosystems suffered one of the greatest biogeographical events, after the establishment of the Panamian land bridge, called the “Great American Biotic Interchange” (GABI). This refers to the exchange, in several phases, of land mammals between the Americas; this event started during the late Miocene with the appearance of the Holartic Procyonidae (Huayquerian Age) in South America and continues today. The major phases of mammalian dispersal occurred from the Latest Pliocene (Marplatan Age) to the Late Pleistocene (Lujanian Age). The most important and richest localities of Late Miocene-Holocene fossil vertebrates of South America are those of the Pampean region of Argentina. There are also several Late Miocene and Pliocene localities in western Argentina and Bolivia. Other important fossils have been collected in localities of Pleistocene age outside Argentina: Tarija (Bolivia), karstic caves of Lagoa Santa and the recently explored caves of Tocantins (Brasil), Talara (Perú), La Carolina (Ecuador), Muaco (Venezuela), and Cueva del Milodon (Chile), among others. The book discusses basic information for interpreting the GABI such as taxonomic composition (incorporating the latest revisions) at classical and new localities for each stage addressing climate, environments, and time boundaries for each stage. It includes the chronology and dynamics of the GABI, the integration of South American mammalian faunas through time, the Quaternary mammalian extinctions and the composition of recent mammalian fauna of the continent.
