Tadpoles of the United States
and Canada: A Tutorial and Key
A key for the tadpoles of the United States and Canada features a different
format and approach to identifying frog larvae. More details of ontogenetic
variation are included than in many keys, and more attention is paid to using
characteristics of living tadpoles. A tutorial examines morphological traits,
and color photographs are included to simplify the identification process.
US Amphibians
Distribution Maps
Welcome to the Status and Conservation of US Amphibians distribution maps
website. These maps represent documented and assumed distributions from museum
records, data published in the primary literature, state/regional field guides,
or as submitted from state/regional experts. These distributions represent
records of occurrence. Data documenting declines, extirpations, and extinctions
have not yet been incorporated.
Key to the Amphibians
of Canada
A key is a guide to identifying an organism based on the characteristics which
distinguish it from related organisms. A key is most useful when you have
the animal in hand, but it is sometimes possible to "key out" an animal based
on a photograph or detailed description. As you become more familiar with
the amphibians of Canada, you will get better at describing the animals you
see and it will become easier to use the key.

Amphibians of Alberta
Within Alberta there are 10 species of amphibians: two salamanders and eight
frogs and toads. The frogs and toads can be subdivided into true toads (three
species), spadefoots (one species), tree frogs (one species), and true frogs
(three species). Alberta Sustainable Resource Development.

A Field Guide to the Reptiles
and Amphibians of Coastal Southern California
The highly developed and urbanized area of coastal Southern California is
host to one of the richest herpetofaunas in the United States and includes
several species with State and Federal protected status. Over the past few
years, we have been conducting an intensive study of the autecology of herptile
communities in the region and saw the pressing need for a well-illustrated
field guide to help train students, researchers, reserve managers, regulators,
and others to identify the local herpetofauna, with emphasis on sensitive
species. Western Ecological Research Center, USGS.
Herpetofauna of the Comanche
National Grasslands, Colorado
Southeastern Colorado is a sparsely inhabited region roughly 145 miles by
135 miles (nearly 20,000 square miles). Much of this area is plains grassland
habitat (short-grass prairie) which supports a large number of terrestrial
species, and amphibians and reptiles make up an important component of this
grassland ecosystem. However, the distribution in Colorado of many species
remains incompletely known due to the large area encompassed and a relative
paucity of extensive, long-term inventory studies conducted. In addition,
many areas have experienced and are currently experiencing extensive changes
of the native grassland prairie, and much of this change is directly attributable
to human activity. As human impact is likely to increase in the near future,
a more complete inventory of the herpetofauna becomes more important to document
the current range of the many species found in this part of Colorado before
they become uncommon or are extirpated. This is a report of activities conducted
in 1995-1997 which were funded in part (1996-1997) by the USDA-Forest Service.
Activities reported here are directly associated with a larger survey of the
herpetofauna of southeastern Colorado funded by the Colorado Division of Wildlife
and the Great Outdoors Colorado program.
Checklist
of Florida Amphibians and Reptiles
The species are listed alphabetically by scientific name, first by genus,
then by species and subspecies.Exotic (non-native) species which have been
introduced (escaped or were released) and now have breeding populations in
Florida are noted. The frequency with which introductions are occurring makes
any list of Florida herps out of date almost as soon as it is compiled. That
undoubtedly is the case with the list that follows. Florida Museum of Natural
History.
The Frogs and
Toads of Georgia
These pages were initiated as a result work done on The Georgia Herp Atlas,
a 5 year volunteer effort to catalog all herps in the state which ended July
2001.

Toads
and Frogs of Minnesota
Toads and frogs often conjure up thoughts of wet places- misty swamps and
enchanted nights when mysterious calls rise from the water's edge. The 14
species of toads and frogs found in Minnesota are grouped into three families:
toads, treefrogs, and true frogs. All species within each family share similar
features, but each individual species has its own unique breeding call, survival
strategy, and environmental niche. By learning more about these amphibians,
their habitats, and their survival methods, Minnesotans can better appreciate
why we need to conserve the wetlands, grasslands, and forests where these
fascinating animals live. Their presence is an indication that we are doing
a good job of preserving wetland habitat and water quality. Conversely, when
toads and frogs disappear, it could mean the ecosystems that sustain them
are ailing. Minnesota Department of Natural Resources.
Reptiles and Amphibians
of Minnesota
This site is designed to introduce you to the herpetology of Minnesota. Here
you'll find detailed species accounts of every snake, turtle, lizard, frog,
toad and salamander that is found in the state.
Missouri's
Amphibians and Reptiles
Missouri has 43 species of amphibians, with an additional five subspecies
or geographic races. No amphibians in Missouri are venomous; they are harmless
to people. The color and variety of salamanders and the calls of toads and
frogs in spring and summer help make our outdoors a fun and lively place to
be. Missouri has 63 species of reptiles: 17 different turtles, 11 different
lizards and 35 different snakes. Only five snake species are venomous to people;
most are shy and normally avoid people. Missouri Dept. of Conservation.
Survey of Amphibians at Selected
Sites in Nebraska
During 1997, collections of larval amphibians were made at 130 sites in Nebraska.
Collections were made during 1 June - 16 July, so as to replicate earlier
samples taken by John D. Lynch in 1971-75. The same sites that Lynch surveyed
were sampled in the recent survey, unless they were no longer present or accessible,
in which case a replacement site within 1.6 km was sought. The overall objective
of the study is to test the hypothesis that amphibian populations have declined
in Nebraska. Results reported here indicate the species found in each county
where collections were made. This study was supported in part by the Grasslands
Ecosystem Initiative, Northern Prairie Wildlife Research Center, U.S. Geological
Survey-Biological Resources Division, Jamestown, North Dakota.

Amphibians
and Reptiles of Long Island, Staten Island and Manhattan (New York)
This web page is a key for identifying the reptiles and amphibians found on
Long Island (L.I.), Staten Island (S.I.) and Manhattan. It is important to
note that Manhattan now hosts only 4-5 species (Bullfrogs, Snapping turtles,
Painted turtles, Red Eared Sliders, and possibly Spring Peepers). Thus, this
web page focuses primarily on Long Island and Staten Island, both of which
still have a substantial number of species. This key does not include the
neighboring mainland U.S areas (New Jersey, Connecticut, or the rest of New
York).
Reptiles and Amphibians of North
Dakota
This guide to reptiles and amphibians of North Dakota is the work of Grand
Forks teachers Ted Hoberg and Cully Gause. It is designed to give the curious
reader a tool to identify some of the least understood of North Dakota's wildlife
species. This resource is based on the following article: Hoberg, T. and C.

Reptiles and Amphibians Southwestern
North Dakota
Distribution maps based on a study of representative terrestrial vertebrates
in the portion of the Missouri Slope south and west of the Missouri River,
and McLean County, in North Dakota was undertaken in the summers of 1976 and
1977. Data were tabulated relative to species occurrence and abundance by
major habitat type and geographic area. Data were collected from population
sampling, existing literature, and unpublished reports and interviews. This
resource is based on the following: Seabloom, R.W., R.D. Crawford & M.G. McKenna

South Carolina
Reptiles and Amphibians
Welcome to our site of information on reptiles and amphibians indigenous to
South Carolina. Our goal for the site is to post pictures of every species
of reptile and amphibian which has established wild populations within South
Carolina. We also try to display pictures emphasizing characteristics useful
in identification. Another goal for this site is to provide anecdotal information
from our encounters with the species.

Wisconsin
Herpetological Atlas Project
The Wisconsin Herpetological Atlas Project (Herp Atlas) tracks the distributions
of amphibians and reptiles in Wisconsin. The Herp Atlas was initiated in 1986
by the Vertebrate Zoology Section of the Milwaukee Public Museum, with the
cooperative support of the Natural Heritage Inventory Program (Bureau of Endangered
Resources, Wisconsin Department of Natural Resources; and the Nature Conservancy,
Wisconsin Chapter). The Herp Atlas is producing a computerized database of
amphibian and reptile distribution, based on records obtained from museum
collections, field surveys, literature, and field notes provided by volunteer
observers throughout the state.
