Generously illustrated, this essential handbook for herpetologists,
ecologists, and naturalists features comprehensive keys to eggs,
embryos, salamander larvae, and tadpoles; species accounts; a
glossary of terms; and an extensive bibliography. The taxonomic
accounts include a summarization of the morphology and basic
natural history, as well as an introduction to published
information for each species. Tadpole mouthparts exhibit major
characteristics used in identifications, and the book includes
illustrations for a number of species. Color photographs of larvae
of many species are also presented. Handbook of Larval Amphibians
of the United States and Canada, written by the foremost experts on
larval amphibians, is the first guide of its kind and will
transform the fieldwork of scientists and fish and wildlife
professionals.
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.
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
With many frog populations declining or disappearing and
developmental malformations and disease afflicting others,
scientists, conservationists, and concerned citizens need
up-to-date, accurate information. "Frogs of the United States and
Canada" is a comprehensive resource for those trying to protect
amphibians as well as for researchers and wildlife managers who
study biodiversity. From acrobatic tree frogs to terrestrial toads,
C. Kenneth Dodd Jr. offers an unparalleled synthesis of the
biology, behavior, and conservation of frogs in North America.
This two-volume, fully referenced resource provides color
photographs and range maps for 106 native and nonindigenous species
and includes detailed information on- past and present
distribution- life history and demography - reproduction and diet-
landscape ecology and evolution- - diseases, parasites, and threats
from toxic substances- conservation and management
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.
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
