Download or read book Behaviour and Ecology of Spiders written by Carmen Viera and published by Springer. This book was released on 2017-11-02 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.
Download or read book Fossil Spiders written by David Penney and published by Siri Scientific Press. This book was released on 2011 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Compared to insects, fossil spiders have received only scant attention in the literature. Previously, the only works available were numerous scientific papers, many published in foreign languages. Most of these are basic descriptive taxonomic works, with very few considering broader biological concepts. Despite a significant increase in the discovery and description of fossil spiders within the last quarter Century this void remained unfilled. Thus, this short monograph aims to achieve several objectives. Firstly, to provide general and up to date background information on the overall importance and diversity of fossils spiders, including an indication of those groups for which the taxonomy is spurious and in need of reassessment. Secondly, to discuss the techniques available for working with fossil spiders and some of the problems encountered by palaeoarachnologists, including bias and limitations of the spider fossil record. Thirdly, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator-prey co-radiations. Finally, the contribution that fossil data can make to understanding the past and present biogeography of the order is considered. This book should be of interest to both amateur and professional arachnologists and palaeontologists and will also serve as a general palaeontological reference work for neonologists studying extant spiders.

Download or read book The New Southeast Asian Goblin Spider Genus Aposphragisma Araneae Oonopidae Diversity and Phylogeny written by and published by . This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new genus Aposphragisma (Araneae, Oonopidae, Oonopinae) comprising the new species A. baltenspergerae, A. borgulai, A. brunomanseri, A. confluens, A. dayak, A. dentatum, A. draconigenum, A. hausammannae, A. helvetiorum, A. kolleri, A. menzi, A. monoceros, A. nocturnum, A. retifer, A. rimba, A. salewskii, A. scimitar, A. sepilok and A. stannum is described. It is characterised by very hard bodied, strongly sclerotized species with completely armoured prosoma and strongly sclerotized ventral and dorsal abdominal scuta. Aposphragisma gen. nov. is placed within the Gamasomorphagroup sensu Saaristo (2001). Descriptions and illustrations are given for all new species. A phylogenetic analysis based on 40 characters using Prethopalpus fosuma, Gamasomorpha asterobothros, G. cataphracta, G. seximpressa, Xestaspis biflocci, X. kandy and X. paulina as outgroup-taxa and Cortestina thaleri (Oonopidae, Sulsulinae) as the root is presented and discussed. Furthermore it is shown that females of Aposphragisma gen. nov. possess complex internal genitalia. The members of the new genus are ground-dwelling litter inhabitants restricted to Southeast Asian lowland and montane forests, with more than 60% of the species only known from single localities. They are presumed to be negatively affected by the massive destruction of pristine forest habitats within their range. This work has been conducted within the framework of the Planetary Biodiversity Inventory (PBI) of Oonopidae (see http://research.amnh.org/oonopidae).

Download or read book The Manchester Museum written by Manchester Museum (University of Manchester) and published by Third Millennium Information. This book was released on 2012-06 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Manchester Museum is the first accessible guide to the collections and activities of the UK's largest university museum and one of the most significant museums in the country. There are approximately 4.5 million objects in the Museum and most are kept in storage, inaccessible to the public. The illustrated guide highlights the growth of each collection area and focuses on the detail of featured items. Initially consisting of the donations of the large collections of Victorian and Edwardian amateurs, they subsequently developed through a combination of continued donations and fieldwork research around the world by academics and curators.This publication traces the history of the Museum, from its beginnings as the collection of the Manchester Society for the Promotion of Natural History, through its transfer to John Owens College, to its current position as a major asset of the University of Manchester. The Manchester Museum frames the discussion of the collections with the Museum's award-winning work with schools and colleges, its wider work to engage its many communities and its use of digital communication to enhance the visitor's interaction with the collections.
Download or read book Sperm Competition and the Evolution of Animal Mating systems written by Robert L. Smith and published by Elsevier. This book was released on 2012-12-02 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sperm Competition and the Evolution of Animal Mating Systems describes the role of sperm competition in selection on a range of attributes from gamete morphology to species mating systems. This book is organized into 19 chapters and begins with the conceptualization of sperm competition as a subset of sexual selection and its implications for the insects. The following chapter describes the relationship between multiple mating and female fitness, with an emphasis on determining the conditions under which selection on females is likely to counteract selection on males for avoiding sperm competition. Other chapters consider the female perspective on sperm competition; the evolutionary causation at the level of the individual male gamete; and the correlation of high paternal investment and sperm precedence in the insects. The remaining chapters are arranged phylogenetically and explore the sperm competition in diverse animal taxa, such as the Drosophila, Lepidoptera, spiders, amphibians, and reptiles. These chapters also cover the evolution of direct versus indirect sperm transfer among the arachnids or the problem for kinship theory presented by multiple mating and sperm competition in the Hymenoptera. This book further discusses the remarkable potential for sperm competition among certain temperate bat species whose females store sperm through winter hibernation and the mixed strategies and male-caused female genital trauma as possible sperm competition adaptations in poeciliid fishes. The concluding chapter examines the predictions concerning testes size and mating systems in the primates and the possible role of sperm competition in human selection. This book is of great value to reproductive biologists and researchers.
