COMPETITIVE ENVIRONMENT AFFECTS FOOD-HOARDING BEHAVIOR OF MERRIAM'S KANGAROO RATS (DIPODOMYS MERRIAMI)

Effects of Food Preference on Scatter-Hoarding by Kangaroo Rats (Dipodomys merriami)

Scatter hoarding by kangaroo rats (Dipodomys merriami) and pilferage from their caches

1045-2249/92/14.00 © 1992 International Society for Behavioral Ecology We observed radio-implanted Merriam's kangaroo rats disposing of 10-g bonanzas of rolled oats in 48 trials in the field. The principal determinant of the initial disposition of discovered food was apparently its distance from the day burrow: food found within about 10m was mainly larder hoarded, whereas food encountered fart...

analysis without significantly affecting intestine weight o r length. If the source of carcasses is unknown, then an analysis of small intestine weight, either as a measure of intestine size o r to examine the effects of dietary, seasonal, sex, o r age differences, should be treated with caution. If the same information can be gained by examining intestine length, this is preferred. Nevertheles...

Aboveground Activity of Merriam's Kangaroo Rats (Dipodomys merriami) in Relation to Sex and Reproduction

Behavioural syndromes in Merriam's kangaroo rats (Dipodomys merriami): a test of competing hypotheses.

Behavioural syndromes, correlations of behaviours conceptually analogous to personalities, have been a topic of recent attention due to their potential to explain trade-offs in behavioural responses, apparently maladaptive behaviour and limits to plasticity. Using Merriam's kangaroo rats (Dipodomys merriami), we assessed the explanatory power and generality of hypothesized syndrome structures d...
