The article discusses research being done on changes in the behavior and foraging habits of elk in the Greater Yellowstone Ecosystem in Montana. It references a study by Scott Creel et al, published in the "Proceedings of the National Academy of Sciences." According to the researchers, wolves have caused changes in the nutrition of elk. Low calving rates, aside from direct predation, is cited as one of the reasons for elk population declines.

    Optimal foraging theory assumes that predators use different prey types to maximize their rate of energetic gain. Studies focusing on prey preference are important sources of information to understand the foraging dynamics of Chrysomya albiceps. The purpose of this investigation is to determine...

    Predation patterns often reflect the abundance and distribution of prey although factors such as vulnerability and ease of prey capture also affect these patterns. Wolves (Canis lupus) rely primarily on ungulates throughout most of their range even though other foods can be locally and...

    Theoretical models and empirical evidence suggest that prey should not flee immediately upon detecting an approaching predator, but instead should adjust their escape response to minimize the costs of flight. Similarly, after deciding to escape, animals should tend to adjust the magnitude and...

    Theory states that an optimal forager should exploit a patch so long as its harvest rate of resources from the patch exceeds its energetic, predation, and missed opportunity costs for foraging. However, for many foragers, predation is not the only source of danger they face while foraging....

    The allocation of time to different behaviours (time budgeting) was examined in common shrews on a foraging grid under conditions of no competition or during conditions of apparent competition. When a confined but detectable competitor was present, several behaviours, but especially those...

  • Arctic fox (Alopex lagopus) diet in Karupelv Valley, East Greenland,during a summer with low lemming density Angerbjorn, Anders; Dalerum, Fredrik // Arctic;Mar2000, Vol. 53 Issue 1, p1 

    We investigated the diet of arctic foxes (Alopex lagopus) in the Karupelv valley, East Greenland, during the summer of 1997. Despite a low density, lemmings were the most utilized prey, comprising 65.3% of dry fecal weight in fresh feces. This demonstrates the importance of lemming species as...

    The desert ant Cataglyphis exhibits a strong tendency toward returning to its previous foraging direction when the last foraging run was successful. This behavior is called sector fidelity. A very simple behavioral rule, the Ï„-rule, has previously been identified as the possible underlying...
