Our results showed that bulls had a significantly higher proportion of C4 grasses in their diet than cows, juveniles, or calves. Diets of calves were of higher quality than diets of bulls, cows, or juveniles. Our results provide support for the sexual dimorphism–body size hypothesis of sexual segregation in large ungulates.10abison10aBos bison10adiet composition10adiet quality10asexual segregation1 aPost, D.M.1 aArmbrust, T.A.1 aHorne, E.A.1 aGoheen, J.  uhttp://129.130.186.12/content/sexual-segregation-results-differences-content-and-quality-bison-bos-bison-diets02106nas a2200217   4500008004100000245011400041210006900155300001300224490000700237520138200244653001201626653000901638653001401647653001301661653002201674653001301696100001501709700001901724700001901743856012601762       1998                        eng d00aInfluence of maternal diet and perishability on caching and consumption behavior of juvenile eastern woodrats0 aInfluence of maternal diet and perishability on caching and cons  a156 -1620 v793 aWe tested the hypotheses that juvenile eastern woodrats (Neotoma floridana) learned to select appropriate foods to cache by cues from the maternal diet and that the effect of perishability affected caching and consumption behavior of juvenile woodrats. 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://129.130.186.12/content/influence-maternal-diet-and-perishability-caching-and-consumption-behavior-juvenile-eastern01907nas a2200241   4500008004100000245013300041210006900174300001300243490000700256520105200263653002701315653002701342653001201369653002201381653001801403653002001421653002101441653002201462653002501484100001501509700001601524856012501540       1995                        eng d00aAntimicrobial activity of dogwood fruits (Cornus drummondii) from winter food caches of the eastern woodrat (Neotoma floridana )0 aAntimicrobial activity of dogwood fruits Cornus drummondii from   a419 -4250 v213 aPost-harvest loss of resources to microbial competitors affects a number of species of animals, and many of them have evolved behaviors that reduce the likelihood of such loss. We previously described the inhibition ofBacillus psychrophilus by dogwood fruits (Cornus drummondii), which can comprise a significant portion of the winter food cache of the eastern woodrat (Neotoma floridana). The present study is a further investigation of the ability of dogwood fruits to inhibit growth ofB. psychrophilus. Additionally, we tested the antimicrobial activity of dogwood fruits onEscherichia coli andStaphlococcus aureus. Results of our study indicate that fresh fruits inhibit the growth ofB. psychrophilus andS. aureus but notE. coli. However, fruits taken from woodrat dens after four and six months storage inhibited growth of all three species of bacteria. Further, the strength of inhibition increased over the test period. We suggest the presence of an inhibitor allows woodrats to compete effectively for a valuable and limited food resource.10aantimicrobial activity10aBacillus psychrophilus10acaching10aCornus drummondii10adogwood fruit10aeastern woodrat10aEscherichia coli10aNeotoma floridana10aStaphlococcus aureus1 aPost, D.M.1 aUrban, J.E.  uhttp://129.130.186.12/content/antimicrobial-activity-dogwood-fruits-cornus-drummondii-winter-food-caches-eastern-woodrat01273nas a2200133   4500008004100000245006500041210006500106300001100171490000700182520083200189100001501021700001601036856008701052       1993                        eng d00aChanges in microbial populations from eastern woodrat caches0 aChanges in microbial populations from eastern woodrat caches  a30 -350 v383 aChange in microbial populations on three plant foods commonly stored over winter by eastern woodrats (Neotoma floridana) was assessed. It was expected that dogwood fruits (Cornus drummondii) would be affected by microbes to a greater degree than ash seed (Fraxinus pennsylvanica) or redbud seed (Cercis canadensis). Results revealed a change in microbial populations over time but dogwood fruit was no more liable to microbial infestation than seeds. One bacterial species was found in high number on all three food types while three species were found on only two of the three foods. Microbial populations from all three test items increased from November to January but March populations were not different from November populations. It is suggested that climatic factors help to control microbial populations on cache foods.1 aPost, D.M.1 aUrban, J.E.  uhttp://129.130.186.12/content/changes-microbial-populations-eastern-woodrat-caches01409nas a2200217   4500008004100000245009200041210006900133300001300202490000700215520071800222653001200940653000900952653002100961653001100982653001700993653002201010100001501032700001901047700001601066856010901082       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://129.130.186.12/content/characteristics-and-significance-caches-eastern-woodrats-neotoma-floridana01166nas a2200121   4500008004100000245009700041210006900138300001300207490000700220520076200227100001500989856004001004       1993                        eng d00aDetection of differences in nutrient concentrations by eastern woodrats (Neotoma floridana )0 aDetection of differences in nutrient concentrations by eastern w  a493 -4970 v743 aI tested the ability of a small generalist herbivore, the eastern woodrat (Neotoma floridana), to detect differences in concentrations of protein, energy, and lipid available in two nutritionally complex diet items. Within 24 h of exposure to diets, woodrats consumed a greater amount of a standard diet than diets reduced in energy or lipid by 5, 10, or 20% and a diet reduced by 20% in protein. However, they did not choose the standard over diets reduced in protein by 5 or 10%. When consumption was summed over the 9-day duration of choice trials, individuals chose the standard diet over reduced diets. The ability of woodrats to detect relatively small differences in nutrient concentrations should allow them to make efficient use of available foods.1 aPost, D.M.  uhttp://www.jstor.org/stable/138240901148nas a2200121   4500008004100000245008500041210006900126300001300195490000700208520069200215100001500907856010400922       1992                        eng d00aChange in nutrient content of foods stored by eastern woodrats (Neotoma florida)0 aChange in nutrient content of foods stored by eastern woodrats N  a835 -8390 v733 a<p>I determined changes in nutrient content of plants cached by eastern woodrats (Neotoma floridana) after 60 and 120 days storage in a cache environment. The energy content of dogwood fruits (Cornus drummondii) declined significantly due to a decline in lipid content. Concentrations of other nutrients in dogwood fruits remained relatively stable as did nutrient concentrations of green ash seed (Fraxinus pennsylvanica) and redbud seed (Cercis canadensis). However, some small fluctuations in nutrients were observed. The decrease in energy content of cache material may have a significant negative impact on some woodrats that have only a limited amount of food stored in caches.</p>1 aPost, D.M.  uhttp://129.130.186.12/content/change-nutrient-content-foods-stored-eastern-woodrats-neotoma-florida00534nas a2200121   4500008004100000245010100041210006900142260004300211300001000254490002100264100001500285856011200300       1991                        eng d00aAn analysis of factors affecting the caching behavior of the eastern woodrat (Neotoma floridana)0 aanalysis of factors affecting the caching behavior of the easter  aManhattan, KSbKansas State University  a1 -910 vPhD Dissertation1 aPost, D.M.  uhttp://129.130.186.12/content/analysis-factors-affecting-caching-behavior-eastern-woodrat-neotoma-floridana00507nas a2200121   4500008004100000245010100041210006900142300001300211490000700224100001500231700001900246856012000265       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://129.130.186.12/content/effects-food-perishability-distance-and-competitors-caching-behavior-eastern-woodrats
