The quality of dispersal depends in large part on factors that affect the post-dispersal fate of seeds, and yet this aspect of dispersal quality is rarely assessed. In the particular case of seed dispersal through endozoochory the defecation pattern produced has the potential of affecting the fate of dispersed seeds and consequently, dispersal quality and effectiveness. In this study, I assessed the effects of dung presence and dung/seed densities on seed predation by rodents and seconclary dispersal by dung beetles. In particular, I compared seed fates in clumped defecation patterns, as those produced by howler monkeys, with seed faces in scattered defecation patterns, as those produced by other frugivores. I also determined the prevalence of red howler monkeys (Alouatta seniculus) as seed dispersers at the plant community level in Central Amazonia by determining the number of species they dispersed in a 25-month period. I found chat dung presence and a-mount affected rodent and dung beetle behavior. Seed predation rates were higher when dung was present, and when it was in higher densities. The same number of seeds was buried by dung beetles, in clumped versus scattered defecation patterns, but more seeds were buried when they were inside large dung-piles versus small piles. Seed density had no effect on rodent or dung beetle behavior. Results indicate that caution should be taken when categorizing an animal as a high or low quality seed disperser before carefully examining the factors that affect the fate of dispersed seeds. Red howler monkeys dispersed the seeds of 137 species during the study period, which is the highest yet reported number for an Alouatta species, and should thus be considered highly prevalent seed dispersers at the plant community level in Central Amazonian terra firme rain forests.}, keywords = {Alouatta, alouatta-palliata, Central Amazonia, defecation pattern, dispersal, Dung beetles, dung beetles scarabaeidae, howler monkeys, los, postdispersal, primary seed dispersal, secondary seed, seed, seed fate, tropical moist forest, tropical rain-forest}, url = {://000176587000008}, author = {Andresen, Ellen} } @article {1318, title = {Effects of season and vegetation type on community organization of dung beetles in a tropical dry forest}, journal = {Biotropica}, volume = {37}, number = {2}, year = {2005}, month = {Jun}, pages = {291-300}, keywords = {Chamela, deciduous forest, dung beetle, Mexico, Seasonality, semideciduous forest, tropical dry forest}, url = {://000229355500018}, author = {Andresen, Ellen} } @article {1323, title = {Possible Indirect Effects of Mammal Hunting on Dung Beetle Assemblages in Panama.}, journal = {Biotropica}, volume = {39}, number = {1}, year = {2007}, pages = {141-146}, keywords = {dung beetle, hunting, mammals, Panama, rain forest, Scarabaeidae}, url = {http://www.blackwell-synergy.com/doi/abs/10.1111/j.1744-7429.2006.00239.x}, author = {Andresen, Ellen and Laurance, Susan G.

Recent studies of terrestrial and understory species of tropical and subtropical forests indicate that the resources available to animals of RFHTL are generally scattered and uncommon. Human populations that utilize this environment contend with a similar pattern of resource availability. On the forest floor only ants and termites, among insects, are consistently common; they are utilized as food by a variety of specialized ground insectivores. Terrestrial herbivores that eat large fallen fruit are also generally scarce as are the often specialized insectivores that seek typically uncommon understory foliage insects, The low densities and high degrees of specialization that accommodate animal species to resources of RFHTL may be ultimately due to a combination of relatively low net primary productivity of undisturbed mature rain forest and the rapid rate of microbial decomposition of forest litter. To develop strategies of conservation suited to RFHTL it will be necessary to understand both the responses of animals to catastrophic disturbances and the often idiosyncratic ways in which animals and people utilize scattered and scarce resources.}, keywords = {dung beetles forest function}, url = {://A1992JB55000010}, author = {Kikkawa, J. and Dwyer, P.

Experiments using 750 thread- marked seeds were performed to investigate seed removal, predation, and caching by terrestrial vertebrates on howler monkey (Alouatta seniculus) defecation sites, where clumps of intact C lucentifolium seeds were observed. Year-to-year variations in seed fare during the peak fruiting period were considered in relation to overall fruit and seed resource availability estimated by a raked-trail survey. The effect of two forest areas, which differed in soil and floristic composition, was examined with conspecific fruiting tree density as a covariant. Exclosure versus open treatment was used to discriminate small rodents (not larger than a spiny rat) from other vertebrates. The presence of fresh howler dung did not affect seed fate after 20 days as shown by comparisons between defecation sites and control during the first year. There was a significant effect of year on the percentage of seeds remaining after 20 days. Low seed removal in 1995 and 1996 (compared to 1997) corresponded to higher overall fruiting and higher fruiting of C lucentifolium, or the presence of alternative resources for rodents. All effect of forest area was observed on the seed removal rate, which varied with years and protection. Comparatively, an effect of forest area on the percentage of seeds lost was observed in 1996 and an effect of treatment on the percentage of seeds eaten was seen in 1995. The mode of seed caching Suggested that spiny rats were the main seed remover. Results of this study suggest that greater seedling recruitment may Occur when large fruit crop and high howler dispersal co-occur with a lower impact of rodents (i.e., when rodents are saturated by abundant and diversified fruit resources such as in 1995).

First, we described the defecation patterns for both primate species. Howler monkeys generally defecated in groups (88\% of observed defecations), with each individual producing on average 31 g of dung, resulting in a large area of the forest floor (31 m(2)) covered by large amounts of dung (clumped spatial pattern). Spider monkeys generally (96\% of observed defecations) defecated individually, each individual producing an average of 11 g of dung, resulting in a small area of the forest floor (2 m(2)) covered by small amounts of dung (scattered spatial pattern). Secondly, we captured dung beetles using as bait the dung of both primate species, to detect differences in the assemblages of these secondary seed dispersers attracted to the dung of both primates. More individual dung beetles, but not more species, were attracted to howler monkey dung than to spider monkey dung. Finally, we assessed experimentally (using plastic beads as seed mimics) how dung type (Ateles vs. Alouatta) and defecation pattern (scattered vs. clumped) affect secondary seed dispersal by dung beetles. We found that post-dispersal seed fate was affected by dung type, with more seeds being buried when present in howler monkey dung, than in spider monkey dung, but was not affected by defecation pattern.

We first review the nascent literature that addresses indirect effects of hunting for tropical forest plant communities. Next, we highlight the potential indirect effects of hunting for other groups of organisms. Our final goal is to consider what could be done to ameliorate the demographic threats to harvest-sensitive game species caused by unsustainable hunting. Three conclusions are possible at this time concerning the impact of hunting for tropical forest plant communities: (1) Hunting tends to reduce seed movement for animal-dispersed species with very large diaspores; (2) Hunting reduces seed predation by granivorous vertebrates for species with large seeds; and (3) Hunting alters the species composition of the seedling and sapling layers. The cascading effects of hunting are already known to affect bruchid beetles and dung beetles and are likely to affect other, nongame taxa. To ameliorate these problems, several lines of research should be further explored to facilitate the development of game management plans including: (1) alternative use of sources of animal protein; (2) income supplementation for local people from sources other than wild meat; (3) outreach and extension activities for communities; (4) recognition and facilitation of the shifting of attitudes towards hunting; (5) implementation of community-based wildlife management programs in regulated-use areas such as extractive reserves; and (6) landscape-scale conservation planning that maximizes the source-sink dynamics of harvested and unharvested game populations and enforces game regulations in strictly protected areas. }, keywords = {bushmeat, management plans, plant community structure, seed dispersal, seed predation}, author = {Stoner, Kathryn E. and Vulinec, Kevina and Wright, S.

The number of colonization attempts in roads was 5 to 10 times greater than in the adjacent vegetation. Experimental transplants indicate that founding-queens are more likely to establish a nest on bare soil than on soil covered with leaf-litter, but the amount of litter covering the ground did not fully explain the preference of queens for dirt roads. Queens that landed on roads were at higher risk of predation by beetles and ants than those that landed in the adjacent vegetation. Nevertheless, greater predation in roads was not sufficient to offset the greater number of colonization attempts in this habitat. As a consequence, significantly more new colonies were established in roads than in the adjacent vegetation.

We sampled dung beetles in the four main vegetative physiognomies of Guriri Island, Esp ́{\i}rito Santo State: forest restinga, restinga Clusia, disturbed restinga (from burning events), and pastures. We placed four sets of two pitfall traps (baited with horse and human dung) in four independent areas of each vegetation type, and collected 14,534 individuals of 13 dung beetle species. Neither log 10 of individuals nor log 10 of species richness were good predictors of restinga disturbance. However, a significant amount of variation in dung beetle abundance and richness could be explained by bait type. Ordination of these sites using hybrid multidimensional scaling revealed a gradient of habitat disturbance from undisturbed restinga samples to pasture. Dung beetle communities along this gradient demonstrated a complete turnover in species composition, from restinga-specialists to invasive and generalists species respectively. This complete turnover signals the local extirpation of forest-adapted species in disturbed and converted areas. Only a single dung beetle species in preserved restingas is protected by Brazilian law (Dichotomius schiffleri). Given the extent of the clearing of restinga habitat, the conservation status of dung beetles associated with restinga forest gives cause for concern. }, keywords = {biological invasion, brazil, coastal ecosystems, Dichotomius geminatus, Dichotomius laevicollis, Dichotomius nisus, Dichotomius schiffleri, Dichotomius semisquamosus, Gromphas lacordairei, insect conservation, Restinga, Scarabaeinae}, author = {Vieira, Leticia and Louzada, Julio N.
