    Intrinsic rate of natural increase in Neotropical forest mammals: relationship to phylogeny and diet (1986)
    Springer

    Notes: Summary The relationship of diet and phylogeny to the intrinsic rate of population increase (r max) was examined in a sample of 39 mammalian species that live in Neotropical forests. Diets of species did not predict their r max, contrary to published predictions based on associations between basal metabolic rate and diet and between basal metabolic rate and r max. Phylogeny did however, apparently because life history characteristics and susceptibility to predation vary predictably with phylogeny and with one another.

    Seasonal Anointment with Millipedes in a Wild Primate: A Chemical Defense Against Insects? (2000)

    Notes: Abstract Members of a wild group of wedge-capped capuchin monkeys (Cebus olivaceus) intentionally anoint themselves with millipedes (Orthoporus dorsovittatus). Chemical analysis revealed these millipedes secrete two benzoquinones, compounds known to be potently repellent to insects. We argue that the secretion that rubs off on the monkeys in the course of anointment provides protection against insects, particularly mosquitoes (and the bot flies they transmit) during the rainy season. Millipede secretion is so avidly sought by the monkeys that up to four of them will share a single millipede. The anointment must also entail risks, since benzoquinones are toxic and carcinogenic. We suggest that for capuchins the immediate benefits of anointment outweigh the long-range costs.

    Vocal regulation of inter- and intragroup spacing during boundary encounters in the titi monkey,Callicebus moloch (1981)
    Springer
    Primates 22 (1981), S. 161-172

    Topics: Biology
    Notes: Abstract Monogamous primates maintain exclusive use of their ranges by regularly defining and reinforcing the conventional location of boundaries.Callicebus moloch males often call alone during the first morning bout, when groups are near boundaries but usually separated by more than 100m. Depending on the location and proximity of neighboring animals, groups might begin duetting and approaching one another. Duetting requires close vocal and spatial coordination of the mated pair, and stimulates the approach of neighboring pairs. At the boundary, vocalizations which keep the pair together and those associated with withdrawal from the boundary increase in proportion. To determine the effect of different calls, I played back recordings of six different vocalizations during two playback experiments, holding location and proximity constant. The responses supported hypotheses generated in the normalistic study, and suggested that at the boundary aggression is primarily intrasexual. Vocalizations and their effects in specified contexts constitute the mechanisms regulating spacing. The resulting spacing patterns maintain resource availability and exclusive access to a mate.

    Vocal regulation of use of space by groups of titi monkeys Callicebus moloch (1979)
    Springer
    Behavioral ecology and sociobiology 5 (1979), S. 1-15 
    Details
    ISSN: 1432-0762
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The daily movements and the resulting activity and calling fields are described for three groups of titi monkeys Callicebus moloch. Groups move to the periphery of their home range in the early morning and then call. Playback experiments confirmed that both proximity and location of calling by neighboring animals affect the group's response. Subsequent countercalling often regulates the approach of neighboring groups to a boundary. After encountering adjacent groups, animals return to areas near the home range center. Movements, calling behavior, and the response to neighboring groups all increase the probability of intergroup encounters in the early morning. Encounters define and reinforce the conventional location of boundaries. Boundaries decrease the probability of intergroup encounters at other times and allow exclusive use of space.
