Scientists believe American alligators have been around for nearly 150 million years, but they came close to going extinct. American Alligator explores the alligator's key role in its habitat, how hunting and habitat changes almost led to its extinction, and how efforts such as egg collection and controlled hunting help to preserve the species. Easy-to-read text, vivid images, and helpful back matter give readers a clear look at this subject. Features include a table of contents, infographics, a glossary, additional resources, and an index. Aligned to Common Core Standards and correlated to state standards. Core Library is an imprint of Abdo Publishing, a division of ABDO.

American alligators live throughout the southeastern United States, slowly swimming through rivers and swamps while looking for their next meal. They snatch up prey in a flash! With few predators once fully grown, American alligators can live to be 50 years old. Learn more about these heavily armored reptiles and their growth from hatchlings to adults in this title for beginning and struggling readers.

ABSTRACT: The purpose of this study was to extend knowledge of the behavioral ecology of alligators in the seasonally fluctuating south Florida environment and then apply this knowledge to develop estimates of alligator detectability for management purposes. I first modeled alligator thermoregulatory response to environmental conditions by investigating emergence rates and using them as an index of heat seeking or heat avoidance. All models indicated a higher probability of emergence in the spring compared to that of the fall. Springtime solar radiation had a positive affect on emergence probabilities. Larger alligators showed a higher degree of heat avoidance in the summer and spent less time emerged than smaller individuals in this study. Body condition also had an effect on emergence rates as alligators with higher body condition scores had higher rates of emergence. I also investigated alligator emergence behavior and how it relates to a variety of environmental variables known to have an effect on crocodilian behavior including season, air and water temperature, moon phase, rain, and wind. Data were analyzed using the GENMOD procedure in the Statistical Analysis System. An Akaike Information Criterion (AIC) for model selection was calculated for each model, and model averaging was performed to come up with a final model that best describes and predicts alligator emergence. Compared to spring and fall, alligators were less likely to be emerged at any given time during summer.

Examination of scalation of American alligators (Alligator mississippiensis) from populations in the eastern and western parts of the species range revealed several scale characteristics that varied between populations and significant variation in the number of transverse ventral rows, number of anterior nuchal scales, number of scales in the anterior dorsal scale row, number of scales in the posterior transverse scale rows, and occurrence of caudal irregularity. Ventral ossification occurs in alligators longer than 165 cm from both the eastern and western parts of the species range. Because of a lack of material from the central part of the alligator's range (Alabama and Mississippi), the nature of this variation cannot be determined.
