Download or read book Priority Effects of Overwintered Rana Tadpoles on Larval Southern Toad Bufo Terrestris Bonnaterre written by Jason P. Hernandez and published by . This book was released on 2010 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: In natural ecosystems, the order of species arrival can impact the development of the community. In the Atlantic Coastal Plain of the Carolinas, wetland ponds exhibit a wide range of hydroperiods, ranging from ponds that dry up in late summer, to those that persist through fall and winter into spring. Ponds that persist through the fall and winter can be colonized by late-summer breeding southern leopard frogs, whose tadpoles must remain in the ponds until the following spring. Tadpoles of spring-breeding anurans, including Southern toads, are adversely affected by the presence of large tadpoles from the prior summer. I examined several mechanisms potentially responsible for this effect: overwintering tadpoles changing the environment during the winter; large tadpoles outcompeting small hatchling tadpoles; interspecific differences in competitive ability between leopard frog and Southern toad; and density-dependent effects. Leopard frog tadpoles had their primary adverse effect on Southern toads through processes occurring during the winter, prior to the arrival of Southern toads. The other mechanisms tested were not significant. The algal resource on which both species depend also showed a response to the presence of overwintered leopard frog tadpoles, being reduced where tadpoles had been present through winter and spring, and increased where overwintered tadpoles were present only in spring. This response did not become apparent until late in the spring, suggesting that resource depletion per se is not the mechanism at work, but that some other process occurring in winter leads to adverse conditions for spring-hatched tadpoles where overwintered tadpoles are present through winter. Because isolated wetlands often do not receive the same level of protection as wetlands connected to navigable waters, important amphibian habitat is often altered by humans in ways that change its habitat value. In managing for optimum biodiversity, it is important to consider the often conflicting needs of different species, and to conserve a range of different pond types of varying hydroperiods and degrees of connectivity.

Available in PDF, EPUB and Kindle. Book excerpt: "The premiere reference book on the 108 species of frogs inhabiting North America north of Mexico. An unparalleled synthesis of the biology and behavior of all native and nonindigenous species, this two-volume, extensively referenced resource has been called the most important book ever published on North American anura. Color photographs and range maps accompany species accounts detailing information on etymology, nomenclature, identification, distribution, fossil record, systematics and geographic variation, life history and ecology, behavior, population and community biology, and conservation. This new edition of the text contains the following updates: Literature citations have been added from 2012 to 2021, now spanning from 1709 to 2021. Distribution maps have been updated, recording the decreased ranges due to declining amphibian populations. Photographs have been revised to ensure the highest digital quality. Anaxyrus williamsi and Lithobates kauffeldi, newly described species, have been included. An account is also included for Gastrophryne mazatlanensis, now recognized as occurring within the United States. Generic keys have been added. A brief section on N.A. frogs in history and art have been added. Nomenclature has been updated (Incilius for Ollotis). Now the only up-to-date and comprehensive resource for those trying to protect amphibians in the US and Canada, as well as for researchers and wildlife managers who study biodiversity"--

Available in PDF, EPUB and Kindle. Book excerpt: This book appears at a time when molecular cytogenetics is positioned to make a significant impact upon evolutionary studies, enabling problems of chromosomal structure and change to be critically assessed. It is an up-to-date and comprehensive survey of the cytogenetics of a major class of animals, including all three amphibian orders, with chapters authored by international leaders in the field.Amphibian Cytogenetics and Evolution will be of interest to classical and molecular cytogeneticists, systematicists, evolutionary biologists, herpetologists, and anyone using amphibians in genetic research. - Offers the only current and comprehensive survey of amphibian cytogenetics - Gives authoritative and in-depth coverage of topics of present interest - Reviews general cytogenetic topics - Presents new insights into evolutionary changes in chromosome structure and amphibian phylogeny and relationships including: Phylogenetic analysis of chromosome data, Current techniques of cytogenetic analysis, Examination of all three amphibian orders
Download or read book The Cayman Islands written by M.A. Brunt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 615 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the course of the last century a considerable amount of scientific work has been carried out in the Cayman Islands. The results of this (outlined in Chapter 1) are widely distributed in unpublished reports, university theses, various scientific publications and books, many of these sources being difficult to find and some now unobtainable. The purpose of this book, therefore, is to bring all this scattered information together and to present a coherent account of the biogeography and ecology of the Islands, as an easily available reference source and as a foundation on which future work can be based.

Available in PDF, EPUB and Kindle. Book excerpt: Between roughly 25 and 31 degrees north latitude, a combination of flat topography, poor soils, and limited surface water produce deserts nearly everywhere on earth. In Florida, however, these conditions support a lavish biota, more diverse than that of any other state east of the Mississippi. In this first comprehensive guide to the state's natural resources in sixty years, thirty top scholars describe the character, relationships, and importance of Florida's ecosystems, the organisms that inhabit them, the forces that maintain them, and the agents that threaten them. From pine flatwoods to coral reef, Ecosystems of Florida provides a detailed, comprehensive, authoritative account of the peninsular state's complex, fragile environments.
