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 Spider Evolution written by Subir Ranjan Kundu and published by Elsevier. This book was released on 2021-10-19 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spider Evolution: Genetics, Behavior, and Ecological Influences is a thorough exploration of the evolutionary trail of arachnids, particularly spider species, through prehistoric origins to current sustainability issues. This book analyzes extinct organisms in the Arachnida class, specifically looking at their phylogenomics and molecular footprints, to understand the evolutionary changes in the diversification in today's spider species. Beginning with an overview of spider species and their cultural significance, this book offers a detailed review of spider origins and their influences on behavioral traits, physiology of sensory organs, and biomechanics. It also touches upon spiders as prey as well as predators, and how these roles have changed in the 400 million years of Arachnida existence. The book then focuses upon current environmental issues facing spider species and how these have, and can, affect the evolution of these organisms; biodiversity minimization, climate change, and natural disasters are covered with consideration to a spider's changing physiology, habitat, and even aggressive behavior. Spider Evolution: Genetics, Behavior, and Ecological Influences is a much-needed resource for entomologists and arachnid- or arthropod-driven researchers. Advanced undergraduate and graduate students will also benefit from the historic review, current assessment, and future predictions of spider evolution provided in this book.

Download or read book All You Need to Know About Spiders written by Wolfgang Nentwig and published by Springer Nature. This book was released on 2022-04-07 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: All You Need to Know About Spiders Spiders are super predators and devour everything they can overpower. To do this, they have developed incredibly good catching techniques and, with spider silk, a tool that makes material technology green with envy. The males are usually smaller than the females and, in order to have sex, they have to come up with a lot to avoid being misunderstood as easy prey: Dancing, drumming, and gifts almost always help. Spiders use their venom in very precise doses, and since humans are not on their menu, they are harmless to us. Many people's (unnecessary) fear of spiders finds cultural roots as early as the Middle Ages. Nevertheless, spider fear is easily treatable. There is no habitat or building without spiders. And that's a good thing, because spiders have fascinating properties and their world is full of surprises. Everything you need to know about them is explained in this book in understandable language by experts for laymen. In addition, some of the most common spider species in the house and garden are briefly presented with tips for observation. The authorsThis book is authored by eight scientists, all of them members of the Association for the Promotion of Spider Research: Wolfgang Nentwig, Jutta Ansorg, Angelo Bolzern, Holger Frick, Anne-Sarah Ganske, Ambros Hänggi, Christin Kropf und Anna Stäubli

Download or read book Conservation Biogeography written by Richard J. Ladle and published by John Wiley & Sons. This book was released on 2011-01-11 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: CONSERVATION BIOGEOGRAPHY The Earth’s ecosystems are in the midst of an unprecedented period of change as a result of human action. Many habitats have been completely destroyed or divided into tiny fragments, others have been transformed through the introduction of new species, or the extinction of native plants and animals, while anthropogenic climate change now threatens to completely redraw the geographic map of life on this planet. The urgent need to understand and prescribe solutions to this complicated and interlinked set of pressing conservation issues has lead to the transformation of the venerable academic discipline of biogeography – the study of the geographic distribution of animals and plants. The newly emerged sub-discipline of conservation biogeography uses the conceptual tools and methods of biogeography to address real world conservation problems and to provide predictions about the fate of key species and ecosystems over the next century. This book provides the first comprehensive review of the field in a series of closely interlinked chapters addressing the central issues within this exciting and important subject.

Download or read book The Biology of Island Floras written by David Bramwell and published by Cambridge University Press. This book was released on 2011-07-21 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.

Download or read book Baseline Survey of Spider Arachnida Araneae Biodiversity at the Lake Superior National Estuarine Research Reserve written by Katie LaPlante and published by . This book was released on 2018 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Baseline surveys of species composition provide researchers with valuable information to form hypotheses regarding the biodiversity, ecological value, and ultimately the health of the surrounding environment. In recent years, as the effects of climate change progress, it is becoming increasingly important to understand the dynamic environment surrounding us and to respond to unwelcome changes with adequate management practices. The objective of this study is to provide an estimate of the number of species present within the Lake Superior National Estuarine Research Reserve (NERR), describe spider assemblages present within major habitat types, and to identify any spider species of conservation concern within the reserve. The location of this study is unique in that it encompasses a large diversity of habitats within the Lake Superior National Estuarine Research Reserve. Repeated sampling was conducted monthly during June, July, August, and September 2017 at multiple sites representing some of the major terrestrial and wetland habitat types on the NERR: Young and mature deciduous forest; conifer forest; old fields and other early successional habitats; riparian and lacustrine sedge meadows and Typha wetlands; and riparian shrub carr. The number of Douglas county spider species records has been increased by 148 to a county record of 163 species. Of the previous 32 Douglas County records, we collected 53.1% in this study. Based off of these values, estimated species richness of Douglas County is 282. Estimate S Richness estimator software (Chao type-1) predicted 222 with a standard deviation of 34, which is comparable to our Douglas county estimate value. Ten new state records, including one national record, have been collected and identified from the NERR. Northernness indices assessed for spiders collected from the NERR exhibit a trend towards species found within the northern range of their current distribution as opposed to the southern range of their distributions. This is evident by contrasting range extensions of seventeen northern range extensions and only one southern range extension among species collected.

Available in PDF, EPUB and Kindle. Book excerpt: A beautifully illustrated guide to the natural history and breathtaking diversity of spiders around the world Spiders are dominant predators in virtually every terrestrial ecosystem on the planet. A marvel of evolution with species numbering in the tens of thousands, they have been walking the earth since before the dinosaurs. Spiders manipulate the silk strands of their webs to act as a sensory field, which vibrates across wide frequencies that they can read in detail, while young spiders spin silk lines that interact with the electrical fields in the atmosphere, enabling them to balloon across huge distances. Some spiders even gather in groups to impersonate ants in astonishing displays of collective mimicry. The Lives of Spiders explores these and other wonders, blending stunning imagery, lively writing, and the latest science to explore the natural history of the world’s diverse arachnid life. Features a wealth of color illustrations Sheds invaluable light on the life history, ecology, and stunning diversity of spiders Covers silk and web building, venoms, predators and prey, mating and dancing, spider cognition, and much more Discusses the impacts of human activity on spiders
