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.10acaching10adiet10ajuveniles10alearning10aNeotoma floridana10awoodrats1 aPost, D.M.1 aMcDonald, M.W.1 aReichman, O.J. uhttp://knz.lternet.edu/content/influence-maternal-diet-and-perishability-caching-and-consumption-behavior-juvenile-eastern00495nas a2200109 4500008004100000245012000041210006900161300001300230100001900243700001900262856010400281 1995 eng d00aThe influence of crowding and pocket gopher disturbance on growth and reproduction of a biennial, Tragopogon dubius0 ainfluence of crowding and pocket gopher disturbance on growth an a123 -1271 aReichman, O.J.1 aHartnett, D.C. uhttp://images.library.wisc.edu/EcoNatRes/EFacs/NAPC/NAPC14/reference/econatres.napc14.oreichman.pdf01391nas a2200169 4500008004100000245005300041210005300094300001300147490000700160520089900167653001201066653000901078653002201087100001501109700001901124856007801143 1994 eng d00aEffects of subterranean herbivores on vegetation0 aEffects of subterranean herbivores on vegetation a852 -8590 v743 aFossorial herbivores are common in Eurasia, North and South America, and Africa, particularly in arid and semiarid regions. There is ample evidence, although often indirect and semiquantitative, that they have local and broad-scale effects on vegetation. These effects arise from feeding, harvesting, and caching, local soil disturbances, and longer-term changes in soil structure and topography, many aspects of which are similar among the diversity of fossorial herbivores. Often, the net effect of these animals' activities is alteration of composition of plant species and increased plant diversity. Standing crop of plants often is reduced, and long- and short-term changes in productivity can occur. Better understanding of the rules that govern diet selection and burrow size, dynamics, and geometry are needed to predict effects of these animals under specific environmental conditions.10aburrows10adiet10afossorial mammals1 aHuntly, N.1 aReichman, O.J. uhttp://knz.lternet.edu/content/effects-subterranean-herbivores-vegetation01410nas a2200217 4500008004100000245009200041210006900133300001300202490000700215520071800222653001200940653000900952653002100961653001100982653001700993653002201010100001501032700001901047700001601066856011001082 1993 eng d00aCharacteristics and significance of the caches of eastern woodrats (Neotoma floridana )0 aCharacteristics and significance of the caches of eastern woodra a688 -6920 v743 aCaches from eastern woodrat (Neotoma floridana) dens were analyzed for plant-species composition, abundance, and energy content. Body mass and sex of den residents and the den volume were measured to determine correlations with energy content of caches. We found no difference between males and females in den volume or energy content of caches. However, a positive correlation existed between body mass of the cache owner and the amount of energy stored in the cache, such that larger individuals had a disproportionately greater reserve of energy stored in caches than did smaller individuals. The disparity suggests that small individuals are forced to forage outside the den more often than large individuals.10acaching10adens10aeastern woodrats10aenergy10afood storage10aNeotoma floridana1 aPost, D.M.1 aReichman, O.J.1 aWooster, D. uhttp://knz.lternet.edu/content/characteristics-and-significance-caches-eastern-woodrats-neotoma-floridana00500nas a2200133 4500008004100000245007600041210006900117300001500186490000700201100001900208700001800227700001900245856010200264 1993 eng d00aDistinct Animal-Generated Edge Effects in a Tallgrass Prairie Community0 aDistinct AnimalGenerated Edge Effects in a Tallgrass Prairie Com a1281 -12850 v741 aReichman, O.J.1 aBenedix, J.H.1 aSeastedt, T.R. uhttp://knz.lternet.edu/content/distinct-animal-generated-edge-effects-tallgrass-prairie-community00508nas a2200121 4500008004100000245010100041210006900142300001300211490000700224100001500231700001900246856012100265 1991 eng d00aEffects of food perishability, distance, and competitors on caching behavior of eastern woodrats0 aEffects of food perishability distance and competitors on cachin a513 -5170 v721 aPost, D.M.1 aReichman, O.J. uhttp://knz.lternet.edu/content/effects-food-perishability-distance-and-competitors-caching-behavior-eastern-woodrats01952nas a2200121 4500008004100000245009600041210006900137300001500206490000700221520146800228100001901696856011501715 1988 eng d00aCaching behavior by eastern woodrats (Neotoma floridana ) in relation to food perishability0 aCaching behavior by eastern woodrats Neotoma floridana in relati a1525 -15320 v363 a

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'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
