Coprophagy by wild ring tailed lemurs lemur catta in human disturbed locations adjacent to the beza mahafaly special reserve madagascar
American Journal of Primatology, 2007Co-Authors: Krista D. Fish, James E. Loudon, Michelle L. Sauther, Frank P. CuozzoAbstract:Coprophagy occurs in a number of animal species, including nonhuman primates. During the 2003-2004 dry seasons at the Beza Mahafaly Special Reserve, Madagascar, we observed wild ring-tailed lemurs (Lemur catta) consuming dried fecal matter from three different species. Ring-tailed lemurs consumed human feces on 12 occasions, cattle feces twice, and feral dog feces once. Coprophagy in this population may be a behavioral adaptation that provides animals access to energy and nutrients and may be an important nutritional source for older, and/or dentally impaired individuals during the dry season.

one reserve three primates applying a holistic approach to understand the interconnections among ring tailed lemurs lemur catta verreaux s sifaka propithecus verreauxi and humans homo sapiens at beza mahafaly special reserve madagascar
2006Co-Authors: James E. Loudon, Michelle L. Sauther, Krista D. Fish, Mandala Hunterishikawa, Youssouf Jacky IbrahimAbstract:We applied cultural anthropological, ethological, and parasitological methodologies to investigate the interplay among three primate species, ring-tailed lemurs (Lemur catta), Verreaux’s sifaka (Propithecus verreauxi), and humans (Homo sapiens) who live within the same habitat (i.e. in sympatry) around the Beza Mahafaly Special Reserve, Madagascar. Through a fusion of these methodologies we hope to provide a holistic understanding of the advantages and disadvantages of human-nonhuman primate sympatry. Interviews and questionnaires provided us with initial insights regarding the local peoples' attitudes toward sympatric strepsirrhine primates. Origin myths indicate a close association between humans, ring-tailed lemurs, and Verreaux’s sifaka, which may serve as an important basis for positive conservation perspectives among the local people. These include lemur hunting taboos and special ancestral forests that are protected against deforestation. However, paleontological data indicate that these cultural perceptions may be of recent origin. Close human-nonhuman primate associations can also have negative effects. We found that some nonhuman primate behavioral activities appear associated with increasing parasite loads, and may act as potential avenues of parasite transmission. Fecal analyses revealed that groups of ring-tailed lemurs that frequented the camp, and interact on a regular basis with humans harbor more endoparasites. These lemur “camp” groups engaged in Coprophagy (fecal ingestion) of human, dog (Canis familiaris), and zebu (Bos indicus) fecal matter. In contrast, analyses of Verreaux’s sifaka fecal matter revealed no parasites. Verreaux’s sifaka were rarely terrestrial, generally avoided humans, and were not observed engaging in Coprophagy. This suggests that each strepsirrhines species’ behavioral patterns and socioecology directly affect its likelihood of acquiring parasitic infections, and this is currently being studied in more depth at the site. We feel that incorporating local people into conservation initiatives are vital for success. This requires an understanding of human-nonhuman primate interconnections, the perspective of local peoples regarding their surroundings, knowledge of nonhuman primate behavior, and epidemiological factors.

increased serum concentrations of secondary bile salts during cholate feeding are due to Coprophagy a study with wild type and atp8b1 deficient mice
Molecular Pharmaceutics, 2006Co-Authors: A K Groen, Cindy Kunne, Ronald Oude P J ElferinkAbstract:Coprophagy (i.e., consumption of feces) is a behavior seen in rodents and other animal species. This behavior can substantially influence the enterohepatic cycling of compounds, including bile salts. Since many studies involve the feeding of rodents with bile salt supplemented diets, it is of importance to know the influence of Coprophagy on bile salt composition in such studies. We compared the peripheral and portal bile salt composition of mice in conventional and metabolic cages when fed a control diet or a diet containing 0.5% cholate. We also performed these experiments with Atp8b1-deficient mice as it has been suggested that in the absence of this transporter bile salt absorption in the intestine would be increased. In mice on a control diet there is little difference in bile salt composition between conventional housing and metabolic housing. Metabolic housing led to a near complete disappearance of the low levels of dihydroxy bile salts (i.e., deoxycholate + chenodeoxycholate) in peripheral serum. In mice fed a control diet, the portal blood concentration of unconjugated dihydroxy bile salts was extremely low ( <2%), but these rose to about 10% when mice were fed a cholate-supplemented diet. In metabolic cages the portal blood content of these unconjugated dihydroxy bile salts was reduced to undetectable levels. Whether housed in conventional cages or in metabolic cages, wild-type and Atp8b1-deficient mice had similar concentrations in portal blood, suggesting that intestinal bile salt absorption is not altered in Atp8b1-deficient mice
