Available information concerning the past and present alligator (Alli~otor mississippiensis) populations in Florida are summarized. Population status is described on the basis of past harvest records, complaint rates, population surveys and opinions of hunters, buyers, and biologists. Based on these data it appears probable that the alligator's past population status was somewhat less serious than previously supposed and the future of the alligator appears secure.

This study comparcs 3 techniques for their effectiveness in detecting lead shot in waterfowl gizzards. X-rays of gizzard contents are more accurate than either X-rays of whole gizzards or manual examination of contents. Manual examination missed 24% and X-rays of whole gi71ards missed at least 28%. The most accurate technique appears to be X-ray of contents with manual verification of all positive X-ray signatures.

A public opinion survey designed to measure human attitudes toward wild alligators (Alligator mississippiensis) and alligator management was carried out. Most \\92%) l"1orida residents view the alligator as a valuable species, but 73% felt that large alligators are dangerous. There was variation in the degree of danger attributed to alligators by various socioeconomic groups. Opinions about management strategies were more variable than for the other topics examined. In urban areas, 52% felt that wildlife officers should capture large alligators, a sizable group (50%) favored commercial...

Accounts of reported alligator attacks in Florida are summarized and examined for evidence of patterns that might explain the causes ofalligator attacks. Twenty-two such incidents were found. Three were provoked, circumstances surrounding 3 were unclear, and the other 16 appeared to be unprovoked attacks. Attacks occurred during the warmer months, usually during late afternoon. Most victims were Florida residents between 9 and 16 years old, most were standing in water or swimming, and none were feeding the alligators at the time ofattack. All except one victim were unaware of the alligator...

Since the summer of 1965, an alligator research program has been conducted in the Everglades of southern Florida. This report describes the progress of the program. Various capture and marking techniques are described and evaluated. Data on growth rates, movement, homing tendencies, and sex and age interpretation from approximately 1,000 tagged alligators are presented. Life history observations, including population trends, activity surrounding a "gator hole", and the effect of water level fluctuation are reported. Man's influences on the alligator population, both from the standpoints of...
