Black-handed spider monkeys (Ateles chamek) are widespread in Rondônia, Brazil, while brown spider monkeys (Lagothrix cana) have a more restricted distribution due to environmental factors and potential competition. Both species tolerate habitat disturbance if hunting pressure is low.

Area of Science:

  • Primate ecology
  • Amazonian biodiversity
  • Wildlife conservation

Background:

  • Two atelid species, Ateles chamek and Lagothrix cana, inhabit southwestern Brazilian Amazonia.
  • Understanding their distribution and ecological interactions is crucial for conservation efforts.

Purpose of the Study:

  • To survey populations of Ateles chamek and Lagothrix cana in Rondônia, Brazil.
  • To analyze factors influencing their distribution and interspecific interactions.

Main Methods:

  • Field surveys conducted at 36 sites across Rondônia.
  • Distributional data collection for both species.
  • Assessment of habitat tolerance and potential competition.

Main Results:

  • Ateles chamek exhibited a widespread distribution.
  • Lagothrix cana's distribution was limited by riverine barriers and ecological factors, potentially including competition with A. chamek.
  • Lagothrix cana groups were larger and more abundant than A. chamek groups, even when found together.
  • Transitional Hylea-cerrado forests did not impede either species.
  • Both species demonstrated tolerance to habitat disturbance under low hunting pressure.

    • Conclusions:

    • Riverine barriers and ecological factors, including interspecific competition, significantly shape Lagothrix cana distribution.
    • Habitat disturbance poses a lower threat to these atelid populations than hunting pressure.
    • Conservation strategies should consider species-specific distributional limits and the impact of human activities.
