Description/Abstract:
IN CONJUNCTION WITH STUDIES OF THE RODENT POPULATIONS OF THE FORMER NU CLEAR TEST SITE AT ENIWETOK ATOLL, THE FEEDING PATTERNS OF RATTUS RATT US AND RATTUS EXULANS WERE DETERMINED BY FOOD ACCEPTANCE TESTS, HISTOL OGICAL EXAMINATION OF STOMACH CONTENTS, AND OBSERVATION OF ANIMALS UND ER BOTH NATURAL AND CAGE CONDITIONS. BOTH SPECIES WERE ACTIVE IN ALL C OMMUNITY TYPES FROM THE EARLY SUCCESSIONAL STAGES TO THE SHRUB-TREE ST AGE. R. EXULANS WAS FOUND MAINLY ON ISLETS HAVING THE REMNANTS OF COCO NUT PLANTATIONS, WHEREAS R. RATTUS OCCURRED ON THOSE EXTENSIVELY DISTU RBED BY NUCLEAR TESTING. PLANT FOODS PREDOMINATED IN THE DIETS OF BOTH SPECIES; HOWEVER, R. RATTUS USED A WIDER RANGE OF FOODS, INCLUDING A VARIETY OF INSECTS. THE APPARENT NARROWER PREFERENCES OF R. EXULANS M IGHT EXPLAIN ITS ABSENCE FROM ISLETS THAT SUFFERED HABITAT DESTRUCTION AND RESTRICTION OF FOOD SOURCES DURING THE NUCLEAR TEST PROGRAM.
