  1. How do rivers, geographic distance, and dispersal behavior influence genetic structure in two sympatric New World monkeys?

    Emilie Lecompte, Mohand-Ameziane Bouanani, Benoît de Thoisy and Brigitte Crouau-Roy

    Alouatta macconnelli and Saguinus midas displayed high genetic diversity and no structuring related with fine scale geographical features. The genetic structure is rather explained by differences in dispersal behavior between species and sexes, either in distance or rate of dispersal.

  2. How far do Neotropical primates disperse seeds?

    Lisieux F. Fuzessy, Charles H. Janson and Fernando A. O. Silveira

    Version of Record online: 27 MAR 2017 | DOI: 10.1002/ajp.22659

    We present a simple model to predict seed dispersal distances by Neotropical primates. Gut transit time, movement rate and path twisting explained 90% of the variation. The model can help evaluate conservation priorities for primates.

  3. Reproductive status affects the feeding ecology and social association patterns of female squirrel monkeys (Saimiri collinsi) in an Amazonian rainforest

    Luana V.P. Ruivo, Anita I. Stone and Matthew Fienup

    Version of Record online: 27 MAR 2017 | DOI: 10.1002/ajp.22657

    1. We examined the effect of reproductive state on the foraging behaviors and social association patterns of female squirrel monkeys in an Amazonian rainforest, over 12 months.
    2. Males and females differed in activity budgets and diets, even when compared at the same time of the year, indicating that reproductive status influences the foraging patterns of female squirrel monkeys.
    3. Gestating females increased their travel time, while decreasing resting time. Lactating females travel less, but increased foraging time and increased time spent in proximity to other females in their group.
    4. Females consumed more insects than males at all times of the year.
    5. Due to their life history and and seasonal breeding, reproduction is an especially costly activity for female squirrel monkeys.
  4. Overlooked small apes need more attention!

  5. Embraces are lateralized in spider monkeys (Ateles fusciceps rufiventris)

    Emily R. Boeving, Starlie C. Belnap and Eliza L. Nelson

    Version of Record online: 27 MAR 2017 | DOI: 10.1002/ajp.22654

    A left side bias was found for embraces in spider monkeys, while there was a trend toward a right bias in grooming. Lateralization patterns may be related to the difference in arousal implicated in risk (i.e., embraces) and routine (i.e., grooming) behaviors.
