Cascading impacts of anthropogenically driven habitat loss: deforestation, flooding, and possible lead poisoning in howler monkeys (Alouatta pigra).

Serio-Silva JC1, Olguín EJ, Garcia-Feria L, Tapia-Fierro K, Chapman CA.
Primates; journal of primatology.Primates.2015 Jan;56(1):29-35. doi: 10.1007/s10329-014-0445-z. Epub 2014 Aug 28.
To construct informed conservation plans, researchers must go beyond understanding readily apparent threats such as habitat loss and bush-meat hunting. They must predict subtle and cascading effects of anthropogenic environmental modifications. This study considered a potential cascading effect of d

The Gut Microbiota Appears to Compensate for Seasonal Diet Variation in the Wild Black Howler Monkey (Alouatta pigra).

Microbial ecology.Microb Ecol.2014 Dec 19. [Epub ahead of print]
For most mammals, including nonhuman primates, diet composition varies temporally in response to differences in food availability. Because diet influences gut microbiota composition, it is likely that the gut microbiota of wild mammals varies in response to seasonal changes in feeding patterns. Such

The role of gut microbes in satisfying the nutritional demands of adult and juvenile wild, black howler monkeys (Alouatta pigra).

Amato KR1, Leigh SR, Kent A, Mackie RI, Yeoman CJ, Stumpf RM, Wilson BA, Nelson KE, White BA, Garber PA.
American journal of physical anthropology.Am J Phys Anthropol.2014 Dec;155(4):652-64. doi: 10.1002/ajpa.22621. Epub 2014 Sep 23.
In all mammals, growth, development, pregnancy, and lactation increase nutritional demands. Although primate field studies tend to focus on shifts in activity and diet as mechanisms to compensate for these demands, differences in digestive efficiency also are likely to be important. Because the gut
