In May 1993, female woodrats were mated and placed on a diet of garlic-flavored chow. Females in group A were fed garlic-flavored chow until offspring were weaned. Females in group B were fed garlic-flavored chow until parturition and then were placed on a diet of standard laboratory chow. All offspring were weaned at 45 days postpartum and maintained on a diet of standard laboratory chow. In October and November 1993, juveniles were tested to determine their preference for caching and consumption of garlic-flavored chow or a novel (mint) flavored chow. Juveniles in group A cached more garlic-flavored chow than juveniles in group B (P = 0.04). There was no difference between groups in the amount of garlic chow consumed (P = 0.5). Naive juveniles preferred to cache dry apple (P = 0.01) but preferred to consume fresh apple (P = 0.01). The outcome of our experiments suggests that maternal diet influences the cache-food selection of naive woodrats. Further, naive juvenile woodrats treat perishable and non-perishable foods in a manner similar to adults suggesting that their response to such foods is not learned.}, keywords = {LTER-KNZ, caching, diet, juveniles, learning, Neotoma floridana, woodrats}, doi = {http://dx.doi.org/10.2307/1382850 }, author = {Post, D.M. and McDonald, M.W. and Reichman, O.J.} } @proceedings {KNZ00514, title = {The influence of crowding and pocket gopher disturbance on growth and reproduction of a biennial, Tragopogon dubius}, year = {1995}, pages = {123 -127}, keywords = {LTER-KNZ}, url = {http://images.library.wisc.edu/EcoNatRes/EFacs/NAPC/NAPC14/reference/econatres.napc14.oreichman.pdf}, author = {Reichman, O.J.}, editor = {D.C.

There is ample evidence, although often indirect and semiquantitative, that they have local and broad-scale effects on vegetation.

Two experiments were conducted on eastern woodrats to determine whether the preference for food items gathered for their caches and the sequence of use of items in the cache varied with perishability. In the first experiment, woodrats were given either 2 kg each of two non- perishable items, laboratory chow and bur oak acorns (which they used more than chow), or 2 kg each of preferred, but perishable, grapes and the non-perishable chow. As hypothesized, the woodrats both ate and stored acorns when they were paired with chow (there would be no advantage to either eating or storing the less-used chow). In contrast, when given grapes and chow, the woodrats continued to eat grapes but stored primarily chow. That is, the utility of the items appeared to change depending on whether they were to be eaten or stored. In the second experiment, woodrats were given excess amounts of chow or grapes that were 2, 4, 6, and 8 days old. They ingested chow in the proportions available, as the chow did not spoil with age. However, they consumed grapes in proportions significantly different from those available. It was anticipated that they would eat the oldest grapes first and store the freshest grapes, but neither this pattern nor any other was obvious in relation to the age of the grapes. The results suggest that woodrats discriminate between food items based on their perishability, and vary their decisions about what to ingest and store accordingly

Although temperature and day length may serve as primary cues for the initiation of caching behavior, the presence of conspecifics, as potential competitors, may also stimulate caching behavior. The purpose of this study was to determine the effects of sight and smell of conspecifics on the caching behavior of P. leucopus. We hypothesized that individuals which can detect other mice would cache more seeds than those isolated from neighbors

Just to the south of Manhattan, across the Kaw River and bordering much of K-177 on the west, lies the largest tract of tall grass prairie remaining in North America, nearly 9,000 integral acres that constitute perhaps the world\&$\#$39;s best on-going scientific research area for this unique, once-vast national resource. Slightly over a century ago, the tall grass prairie stretched over most of what is now Iowa, Illinois, southern Minnesota, northern Missouri, and the edges of the Dakotas, Nebraska, Kansas, and Oklahoma. Today only a minuscule fraction remains. Prairies tend to occur in the interior of large continental land masses. Those processes that generate the growth patterns leading to development of tall grass prairies are carefully explained, illustrating the relationship between the sparse rainfall areas of the west and the smothering effects of the deciduous forests along the most eastern flank. The very conditions that promoted the development of the tall grass prairie, that is, good soil and adequate moisture, have also led to their destruction. As land hungry homesteaders moved west during the 19th century, most of the tall grass prairies were plowed under for farmland. However, that portion of the prairie that lies in the Flint Hills region was unlderlain by limestone ledges. Their thin, shallow, rocky soils made tillage impossible, so that it was cattle that soon replaced the nearly destroyed herds of bison. This book is just not about our large neighbor to the south, but also about grassland ecology in a universal sense and is highly recommended for anyone interested in learning of the history of this vanishing resource, as well as about the on-going research that examines how the ecological system functions and contributes to our total understanding of our universe

We hypothesized that species which regularly cache food should have more diverse diets while feeding on their stores than species which have not evolved general caching behaviors. Such a diet by caching species would tend to reduce the probability of being left with only poor dietary items late in the period of cache use. To test this hypothesis, we designed an experiment to compare the diets of caching and noncaching species following a period of experimental feeding trials which simulated a caching situation
