The Fishes of the Western North Atlantic series, which began
publication in the 1940s by Yale University's Sears Foundation for
Marine Research, was from its beginnings conceived to synthesize
and make accessible the wealth of information in widely scattered
published accounts of the fish fauna of the region for both the
layman and the specialist, presenting critical reviews rather than
compilations. These reference works are still considered valuable
and of interest today to both general audiences and the academic
community. As described in the Preface to the first volume, the
series was "written on the premise that it should be useful to
those in many walks of life-to those casually ... interested ...,
to the sportsman ..., to the fisherman ..., as well as to the
amateur ichthyologist and the professional scientist." These books
remain authoritative studies of the anadromous, estuarine, and
marine fishes of the waters of the western North Atlantic from
Hudson Bay southward to the Amazon, ranking as primary references
for both amateurs and professionals interested in fishes, and as
significant working tools for students of the sea.
This title now includes 30 additional species. Revised and updated
to reflect the most current science, and including 30 new species,
this authoritative and comprehensive volume is the definitive guide
to the amphibians and reptiles of the Carolinas and Virginia. The
new edition features 189 species of salamanders, frogs,
crocodilians, turtles, lizards, and snakes, with updated color
photographs, descriptions, and distribution maps for each species.
It is an indispensable guide for zoologists, amateur naturalists,
environmentalists, backpackers, campers, hikers, and everyone
interested in the outdoors.
Amphibian Conservation is the fourth in the series of Synopses of
Conservation Evidence, linked to the online resource
www.ConservationEvidence.com. This synopsis is part of the
Conservation Evidence project and provides a useful resource for
conservationists. It forms part of a series designed to promote a
more evidence-based approach to biodiversity conservation. Others
in the series include bee, bird, farmland and bat conservation and
many others are in preparation. Approximately 32% of the 7,164+
amphibian species are currently threatened with extinction and at
least 43% of species are declining. Despite this, until recently
amphibians and their conservation had received little attention.
Although work is now being carried out to conserve many species,
often it is not adequately documented. This book brings together
and summarises the available scientific evidence and experience
relevant to the practical conservation of amphibians. The authors
consulted an international group of amphibian experts and
conservationists to produce a thorough summary of what is known, or
not known, about the effectiveness of amphibian conservation
actions across the world. "The book is packed with literature
summaries and citations; a veritable information goldmine for
graduate students and researchers. It also admirably provides
decision makers with a well-researched resource of proven
interventions that can be employed to stem/reverse the decline of
amphibian populations." -John G Palis, Bulletin of the Chicago
Herpetological Society
Host to more than one hundred species of reptiles and amphibians,
the Savannah River Site, a 780-square-kilometer tract in South
Carolina, is one of the most intensely studied areas of
herpetological ecology in the world. This guide is a summary of
basic information on the site's richly varied herpetofauna, from
their taxonomy and distribution to their behavior and habitats.
Keys to identify the adult and larval forms of the site's known
species comprise the core of the guide. These keys are supplemented
by maps, graphs, and illustrations as well as by information on
habitats; population characteristics and distribution; behavior
related to movement, feeding, and reproduction; morphology; and
techniques for collecting specimens. The guide also includes
information about special identification and study problems
involving unresolved sighting reports; subspeciation; and venomous,
edible, endangered, and introduced species. Finally, a bibliography
gives not only the sources referred to in the guide but virtually
all studies and reports based on herpetological research conducted
at the Savannah River Site. The site-related publications are
listed by author but can also be found through an index to the
subjects they cover. Guide to the Reptiles and Amphibians of the
Savannah River Site is a valuable one-volume introduction to the
existing information on herpetofauna at the site and to the
countless research opportunities the site still presents. Because
it is clearly written and designed and lists most of the reptiles
and amphibians found in Georgia and South Carolina, the guide is
also useful to wildlife observers--professional and amateur--in
those states.
Reef Aquarium Success - Volume 1: Learn How To Maintain A Beautiful
Mini-Ocean Environment Within Your Tank" is Volume 1 of the
original electronic book "Reef Keeping Basics - Successful Reef
Management." To assist in the marketing and promotion of that
original book, the author - Eric V. Van Der Hope, decided to
publish a paperback version of the book. Also, because the original
electonic book comprised over 700 pages & over 300 colorful
images, it wasn't cost effective to produce as a single printed
book. Thus, "Reef Aquarium Success - Volume 1" has become part 1 of
an extremely informative and educational resource.About "Reef

"Reptiles and Amphibians of Price Edward County, Ontario" is a
comprehensive look at the little-known residents of a well-known
corner of rural Ontario. Complete with descriptions and
illustrations, the book provides serious and amateur naturalists
with a thorough compilation of recent and historic reports of the
some thirty species of turtles, snakes, frogs, toads and
salamanders that are -- or once were -- found in this unique part
of the province. The text acquaints readers with the likelihood of
encountering these fascinating creatures in the area while maps of
all known records illustrate where these animals have been
uncovered in the past. Discussions of changes in species abundance
offer a sense of the shifts that have taken place in reptile and
amphibian communities in the area over time.
This edited volume explores the various views on the origins of
tetrapods-amphibians, reptiles, birds, and mammals-views that agree
or differ depending in part on how certain fossil animals are
classified and which methodology is used for classification.
Eighteen chapters by an international group of paleontologists and
neontologists here present current hypotheses, emphasizing the
kinds of data needed to answer controversial questions, as well as
the variety of solutions that emerge from diferent analyses of the
same data set. The book is arranged in five sections, each of which
contains an overview essay that either describes the development of
various schools of thought regarding the origin of the tetrapod
group in question or critically summarizes the arguments presented
in the section. The first section addresses the origins of
tetrapods as a group, focusing on lobe-finned fishes and early
tetrapods. Next is a section dealing with amphbians, followed by
one on reptiles. The fourth section concerns avian origins, and the
final section treats the origins and early diversification of
mammals. With an overall goal of stimulating critical evaluation by
the reader rather than providing unequivocal answers, this volume
will be of particaular interest to vertebrate paleontologists,
evolutionary morphologists, and ichthyological, herpatological,
avian, and mammalian systematists.
Amphibian skin has, over the last century, proven to contain a
treasure-trove of biologically active compounds. Since that time
further investigation has added hundreds of such compounds to the
list of active substances from amphibian skin. Peptides, proteins,
bufadienolides steroids and alkaloids (tetrodotoxins, biogenic
amines and lipophilic alkaloids) represent the main compounds found
in the amphibian skin. This book discusses the anatomy of
amphibians. It also provides topics on the ecological significant
and conservation strategies of these marine animals.
In this book the authors present current research in the study of
frogs. Frog's neuromuscular junction (NMJ) is a classic and
favourite object which have played a leading role in developing
understanding of the basic mechanisms of synaptic transmission and
secretion of neuromediator. The genetic diversity, neural
development and ecological implications of frogs are examined
throughout the book. Some of the topics the authors discuss in this
compilation include poison storage and maturation in serous
cutaneous glands of anurans; a mini review of the suppression of
anuran metamorphosis by synthetic chemical compounds; mechanisms of
suprathreshold excitation of a frog tectal neuron column by
discharge of a single moving edge or darkness detector and their
relation to a frog escape reactions; behavioral, ecological, and
evolutionary aspects of diversity in frog colour patterns;
physiological features of blood's system of frogs rana ridibuda
pall; and presynaptic voltage-dependent calcium channels at the
frog neurmuscular junction.
This profusely illustrated comprehensive key for identifying
amphibians and reptiles from the continental United States and
Canada incorporates a wealth of scientific findings. Since the
first edition was published in 1998 and the second in 2012, the
number of currently recognized species of native amphibians and
reptiles in the area covered by this key has increased from 545 to
634 to 685, and the number of established non-native species has
increased from 39 to 58 to 67. The increase in native taxa reflects
the dynamic nature of modern systematics and the use of new
(especially molecular) techniques to elucidate relationships and
redefine species boundaries. The increase in non-native species
reflects the porosity of the North American borders when it comes
to controlling animal imports. The key is easy to use and
illustrated with outstanding line drawings that show details of
color patterns and structures used for identification. To
accommodate the additional taxa, the number of line drawings in
this third edition has increased from 257 to 279 to 295. In
addition, nine maps illustrate the distributions of species that
have been recognized since the publication of maps in the most
recent editions of the Peterson Field Guides to the reptiles and
amphibians of eastern, central, and western North America. A large
number of annotations detail current taxonomic ambiguities or
disagreements and the literature cited has been expanded.
Collectively these features enhance opportunities to teach and
learn the classification and identification of amphibians and
reptiles in the continental United States and Canada.
In this book, the authors gather and present topical research from
across the globe in the study of the biology, ecology and uses of
frogs. Topics discussed include using frog red blood cells for
exploring the ion transport pathways across cellular plasma
membranes and their regulation; the significance of retinal glial
cells for glutamatergic neural transmission in frog retina; a
review of the intraspecific patterns and differences in
life-history traits of frog populations living at different
altitudes; the peripheral nervous system in the frog as a tool to
examine the regulation of the transmission of neuronal information;
ecological traits in the Omei treefrog in western China; taxonomic
patterns of tadpole behavioural responses to alarm cues and frogs
and toads used as bioindicator organisms in pollution studies.
Frogs and toads have become canaries in the coal mine when it
comes to conservation, as the discovery of malformed frogs has
brought increased attention to global habitat loss, declining
biodiversity, and environmental pollution. Midwestern species of
frogs and toads--already declining due to habitat loss from
agriculture--have been greatly affected by this worldwide
phenomenon. VanDeWalle includes a complete description of each
species along with distinguishing characteristics for three
subspecies, information about range and habitat preferences, diet,
types of calls, and breeding season.
This book covers bog frogs, spring peepers, and more.With more than
forty native and introduced species of frogs and toads occurring in
the southeastern United States, the region represents the heart of
frog and toad diversity in the country. Renowned herpetologists
Mike Dorcas and Whit Gibbons provide us with the most comprehensive
and authoritative, yet accessible and fun-to-read, guide to these
sometimes wet, sometimes warty wonders of nature.Dorcas and Gibbons
enumerate the distinguishing characteristics of frogs and toads,
including how they are different from other amphibians and the
differences between a frog and a toad. Also discussed are the
morphology of frogs and toads, the main groups to be found in the
Southeast, and their habitats. Individual species accounts contain
a physical description of the species plus information about
distribution and habitat, behavior and activity, food and feeding,
predators and defense, calls and vocalizations, reproduction and
description of eggs and tadpoles, and conservation. Accompanying
each account are photographs illustrating typical adults and
variations and distribution maps for the Southeast and the United
States.Given the recent worldwide decline in amphibian populations
and increasing scientific and popular concern for what these
declines mean for all other organisms, ""Frogs and Toads of the
Southeast"" will appeal to people of all ages and levels of
knowledge interested in natural history and conservation. The guide
will help foster the growing interest in frogs and toads as well as
cultivate a desire to protect and conserve these fascinating
amphibians and their habitats.It provides a conservation-oriented
approach. It includes approximately 250 color photographs. It
contains approximately 45 distribution maps. It provides a clear
description and photographs of each species in both tadpole and
adult stages. It includes chapters on identification,
vocalizations, reproduction, global diversity (including remarkable
species such as the gastric brooding frog, poison dart frogs, and
saltwater frogs), and introduced species.
