Book excerpt: This study presents an integrative approach to phylogeography and species delimitation that includes genetics, ecology, and morphology and applies this approach to the study system Rana sphenocephala, a widely distributed leopard frog. The taxonomic history of R. sphenocephala is plagued by decades of controversy, and two morphological subspecies are currently recognized. This study aims to reconstruct the evolutionary history of R. sphenocephala and resolve controversy over the taxonomic status of the subspecies. Phylogenetic analyses of the ND1 mitochondrial gene revealed two distinct lineages: a western and an eastern lineage, with a 4.34% sequence divergence. The geographic distributions of these two lineages, which diverged approximately 3 mya, do not correspond to that of the traditionally recognized subspecies. A nested clade phylogenetic analysis (NCPA) showed allopatric fragmentation to be the original source of lineage divergence, followed more recently by isolation by distance and range expansion. Spatially-explicit analyses of genetic structure (e.g. Monmonier's algorithm) helped to further resolve phylogeographic patterns. The extent of ecological divergence between the eastern and western lineages was quantified by overlap comparisons (D and I in ENMTools) of the Maxent ecological niche models and indicated that the two lineages inhabit different environmental niches. However, climate was found to not be a major driver of lineage divergence in R. sphenocephala. When climate data were examined in a cluster analysis and spatially reprojected, a pattern consistent with the geographic distribution of the subspecies resulted, suggesting a link between climate and morphology that may be the focus of future studies. The results from this study suggest that the eastern and western lineages are evolving separately and support their recognition as separate species. Because the type locality for R. sphenocephala is in Florida, the range of R. sphenocephala is recircumscribed to encompass only the range of the eastern lineage.

Gustin and published by . This book was released on 2009 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Determining the distribution of a species is an important component in understanding the history of a species and determining where future conservation efforts may lead. The geographic distribution of a species can be shaped by several factors such as environmental changes, interspecies competition, and hybridization. In Kentucky, an area of cohabitation occurs between the northern leopard frog (Rana pipiens), which is a species of special concern in Kentucky, and the southern leopard frog (R. sphenocephala), which is a relatively common species in the state. The distributions of these two species are not completely clear due to their similarity in morphology and possibility of hybridization, thus, the use of genetic markers for identification of these species is necessary. The mitochondrial 16S rRNA gene was sequenced for 169 individuals from 37 populations spanning the species range overlap in Kentucky, along with 1 locality in Ohio and 1 locality in Tennessee. Haplotype networking and maximum parsimony analyses separated individuals into 3 unresolved clades. The R.pipiensGROUP included individuals from Ohio and the northernmost counties of Kentucky, which are nested in the R. pipiens range. The R.sphenocephalaGROUP included individuals from Tennessee and the southwest counties of Kentucky, which are nested in the R. sphenocephala range. The R.palustrisGROUP included both pickerel frogs (R.palustris), and individuals with a leopard frog morphology from counties located in central Kentucky. Discrepencies between morphological identification and genotype between pickerel frogs and leopard frogs suggest a genetic interaction. Further genetic analysis of a more variable fragment of the mtDNA, along with greater sampling across the species' range edges may help explain this phenomenon.

Book excerpt: Destruction of habitat due to urban sprawl, pollution, and deforestation has caused population declines or even extinction of many of the world's approximately 2,600 snake species. Furthermore, misconceptions about snakes have made them among the most persecuted of all animals, despite the fact that less than a quarter of all species are venomous and most species are beneficial because they control rodent pests. It has become increasingly urgent, therefore, to develop viable conservation strategies for snakes and to investigate their importance as monitors of ecosystem health and indicators of habitat sustainability. In the first book on snakes written with a focus on conservation, editors Stephen J. Mullin and Richard A. Seigel bring together leading herpetologists to review and synthesize the ecology, conservation, and management of snakes worldwide. These experts report on advances in current research and summarize the primary literature, presenting the most important concepts and techniques in snake ecology and conservation. The common thread of conservation unites the twelve chapters, each of which addresses a major subdiscipline within snake ecology. Applied topics such as methods and modeling and strategies such as captive rearing and translocation are also covered. Each chapter provides an essential framework and indicates specific directions for future research, making this a critical reference for anyone interested in vertebrate conservation generally or for anyone implementing conservation and management policies concerning snake populations.

Available in PDF, EPUB and Kindle. Book excerpt: Crawfish Frogs (Rana areolata) have been called the most secretive frog in North America, and it is unusual in the twenty-first century – in the most scientifically advanced country in the world – that basic discoveries can still be made on an animal that inhabits a quarter of the United States. This is not only a story of the biology of Crawfish Frogs, but a case study of discovery. This volume describes the life history and natural history critical to the survival of the endangered amphibian and recommends management actions to ensure persistence. The authors tell an optimistic conservation biology story and fill a gap between science and the public. The authors have compiled and summarized the peer-reviewed literature on the biology of Crawfish Frogs, which may be one of the most interesting frogs in North America (that nobody knows about).

Book excerpt: This edited volume is a timely and comprehensive summary of the New Zealand lizard fauna. Nestled in the south-west Pacific, New Zealand is a large archipelago that displays the faunal signatures of both its Gondwanan origins, and more recent oceanic island influences. New Zealand was one of the last countries on Earth to be discovered, and likewise, the full extent of the faunal diversity present within the archipelago is only just starting to be appreciated. This is no better exemplified than in lizards, where just 30 species (20 skinks, 10 geckos) were recognized in the 1950s, but now 104 are formally or informally recognized (61 skinks, 43 geckos). Thus, New Zealand contains one of the most diverse lizard faunas of any cool, temperate region on Earth. This book brings together the world’s leading experts in the field to produce an authoritative overview of the history, taxonomy, biogeography, ecology, life-history, physiology and conservation of New Zealand lizards.

Available in PDF, EPUB and Kindle. Book excerpt: Wetlands are among the world’s most valuable and most threatened habitats, and in these crucially important ecosystems, the invertebrate fauna holds a focal position. Most of the biological diversity in wetlands is found within resident invertebrate assemblages, and those invertebrates are the primary trophic link between lower plants and higher vertebrates (e.g. amphibians, fish, and birds). As such, most scientists, managers, consultants, and students who work in the world’s wetlands should become better informed about the invertebrate components in their habitats of interest. Our book serves to fill this need by assembling the world’s most prominent ecologists working on freshwater wetland invertebrates, and having them provide authoritative perspectives on each the world’s most important freshwater wetland types. The initial chapter of the book provides a primer on freshwater wetland invertebrates, including how they are uniquely adapted for life in wetland environments and how they contribute to important ecological functions in wetland ecosystems. The next 15 chapters deal with invertebrates in the major wetlands across the globe (rock pools, alpine ponds, temperate temporary ponds, Mediterranean temporary ponds, turloughs, peatlands, permanent marshes, Great Lakes marshes, Everglades, springs, beaver ponds, temperate floodplains, neotropical floodplains, created wetlands, waterfowl marshes), each chapter written by groups of prominent scientists intimately knowledgeable about the individual wetland types. Each chapter reviews the relevant literature, provides a synthesis of the most important ecological controls on the resident invertebrate fauna, and highlights important conservation concerns. The final chapter synthesizes the 15 habitat-based chapters, providing a macroscopic perspective on natural variation of invertebrate assemblage structure across the world’s wetlands and a paradigm for understanding how global variation and environmental factors shape wetland invertebrate communities.

Book excerpt: This volume is based on a workshop "Modulation of Synaptic Transmission and Plasticity in Nervous Systems" held in n Ciocco, Castelvecchio, Pascoli, Italy, from September 8th to 13th, 1987. The purpose of the meeting was to bring together scientists working on plasticity in nervous systems on different levels. The contributions can be subgrouped into six fields of research: 1) Presynaptic Modulation of Chemical Neurotransmission 2) Postsynaptic Signal Transduction 3) Modulation of Synaptic Transmission and Plasticity in the Hippocampus 4) Modulation of Neuromuscular Transmission 5) Molecular and Cellular Analysis of Conditioning in Marine Snails 6) Analysis of Learning and Memory in Insects Understanding how nervous systems and in particular our brain processes and stores information has been a major challenge in science for centuries and will remain for some time to come. Not until recently neurobiologists agreed to seek plasticity of behavior primarily in the modulation of the properties of synapses between nerve cells. This is to be understood within the context provided by a neural circuitry. An important stimulus came from the work on the marine snail Aplysia, where learning processes can be described as a modulation of transmitter release, traced back to a complete chain of molecular events in an identified neuron. Learning became a topic of molecular biology. Three systems appear particularly promising for this approach: insects, in particular Drosophila, marine snails and the mammalian hippocampal tissue. Our views on neurotransmission have rapidly changed.
