剥夺食物对雄性长爪沙鼠贮食行为的影响
Effect of food deprivation on food hoarding behavior by male Mongolian gerbils (Meriones unguiculatus)
摘要
Abstract
Compensatory increases in food hoarding are commonly observed after a period of food deprivation in some species,including laboratory rats and Siberian hamsters.However,faced with food deprivation,the changes of food hoarding are different in male Mongolian gerbils (Meriones unguiculatus).In the study,gerbils were undergoing food deprivation for daily 22 hours consecutive 3 days or 20 days,or 48 hours fast and measured food hoarding.After they were sacrificed and body fat and serum leptin were measured.For example,daily food deprivation for 22 hours could induce food hoarding in some,but not all,gerbils that normally did not display food hoarding.However,increases in energy challenge (repeated 3 days or 20 days food deprivation,or 48 hours fast) didn't induce food hoarding in gerbils that didn't display food hoarding under food deprivation condition.Further,male Mongolian gerbils also exhibited a bimodal expression of food hoarding with free access to food.We did not detect relationships between food hoarding and body weight,body fat,or serum leptin levels.Combined these data suggest that food deprivation is an important factor to induce food hoarding,but food hoarding is not influenced by increases in food deprivation in male Mongolian gerbils.关键词
