Download or read book Sympatric Diversification in the Upper Amazon written by Robert Carroll Busby and published by . This book was released on 2017 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Neotropical lycaenid hairstreak genus Paraspiculatus is unusual because of a high frequency of sympatry in the Upper Amazon Basin coupled with negligible interspecific variation of male genitalic structures and absence of male secondary sexual traits. Male sexual structures are postulated to promote species recognition by females and to contribute to reproductive isolation, for which reason a high incidence of sympatry in Paraspiculatus would not be expected. A revision of Paraspiculatus was feasible because we increased the number of study specimens more than five-fold (by the extensive use of rotting fish as a bait for males) and sequenced the "barcode" part of the mitochondrial gene CO1 for almost all species. We recognize 19 Paraspiculatus species based on male wing patterns, of which ten are newly described and registered with ZooBank. We partition the 19 species into ten species complexes, which are monophyletic in all analyses of morphological characters, CO1 sequences, and a combined dataset. Male Paraspiculatus are attracted to traps baited with rotting fish in eastern Ecuador, but elsewhere this attraction is less frequent or absent. Using the behavior of other eumaeines as context, we briefly discuss these observations with respect to Paraspiculatus biology. Ten of 19 Paraspiculatus species are sympatric in the Upper Amazon Basin below 1,250 m. Five of these sympatric species are from a single species complex. This instance of apparent in situ diversification is responsible for much of the sympatric diversity in Paraspiculatus in the Upper Amazon Basin."--Provided by publisher.
Download or read book Measuring Arthropod Biodiversity written by Jean Carlos Santos and published by Springer Nature. This book was released on 2020-11-11 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a wide range of sampling methods for investigating different arthropod groups. Each chapter is organized to describe and evaluate the main sampling methods (field methods, materials and supplies, sampling protocols, effort needed, and limitations); in addition, some chapters describe the specimen preparation and conservation, species identification, data collection and management (treatment, statistical analysis, interpretation), and ecological/conservation implications of arthropod communities. The book aims to be a reference for zoologists, entomologists, arachnologists, ecologists, students, researchers, and for those interested in arthropod science and biodiversity. We hope the book will contribute to advance knowledge on field assessments and conservation strategies. Arthropods represent the most speciose group of organisms on Earth, with a remarkable number of species and interactions still to be described. These invertebrates are recognized for playing key ecological roles in terrestrial, freshwater and marine ecosystems. Because of the increasing and relentless threats arthropods are facing lately due to a multitude of human induced drivers, this book represents an important contribution to assess their biodiversity and role in ecosystem functioning and generation of ecosystem services worldwide.
Download or read book Amazonia Landscape and Species Evolution written by Carina Hoorn and published by John Wiley & Sons. This book was released on 2011-09-26 with total page 869 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on geological history as the critical factor in determining the present biodiversity and landscapes of Amazonia. The different driving mechanisms for landscape evolution are explored by reviewing the history of the Amazonian Craton, the associated sedimentary basins, and the role of mountain uplift and climate change. This book provdes an insight into the Meso- and Cenozoic record of Amazonia that was characterized by fluvial and long-lived lake systems and a highly diverse flora and fauna. This fauna includes giants such as the ca. 12 m long caiman Purussaurus, but also a varied fish fauna and fragile molluscs, whilst fossil pollen and spores form relics of ancestral swamps and rainforests. Finally, a review the molecular datasets of the modern Amazonian rainforest and aquatic ecosystem, discussing the possible relations between the origin of Amazonian species diversity and the palaeogeographic, palaeoclimatic and palaeoenvironmental evolution of northern South America. The multidisciplinary approach in evaluating the history of Amazonia has resulted in a comprehensive volume that provides novel insights into the evolution of this region.
Download or read book Origin of Tropical Diversity From Clades to Communities written by James Edward Richardson and published by Frontiers Media SA. This book was released on 2017-01-12 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume we aimed to assess progress in determining the processes by which current patterns of tropical biodiversity were established and are maintained. Tropical regions are highly species-rich and we present studies that have improved our understanding of the generation of that diversity at local, regional and global scales. We demonstrate how diverse fields from molecular phylogenetics, phylogeography, palaeontology and palaeoecology continue to improve our understanding of the natural history of the tropics.

As a comprehensive volume on the subject, the book will serve as both an introduction to the study of electroreception and a reference and review volume for researchers in related fields.
Download or read book The Ecology and Evolution of Heliconius Butterflies written by Chris D. Jiggins and published by Oxford University Press. This book was released on 2017-01-27 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Heliconius butterflies are one of the classic systems in evolutionary biology and have contributed hugely to our understanding of evolution over the last 150 years. Their dramatic radiation and remarkable mimicry has fascinated biologists since the days of Bates, Wallace, and Darwin. The Ecology and Evolution of Heliconius Butterflies is the first thorough and accessible treatment of the ecology, genetics, and behaviour of these butterflies, exploring how they offer remarkable insights into tropical biodiversity. The book starts by outlining some of the evolutionary questions that Heliconius research has helped to address, then moves on to an overview of the butterflies themselves and their ecology and behaviour before focussing on wing pattern evolution, and finally, speciation. Richly illustrated with 32 colour plates, this book makes the extensive scientific literature on Heliconius butterflies accessible to a wide audience of professional ecologists, evolutionary biologists, entomologists, and amateur collectors.
