Effect of colour vision status on insect prey capture efficiency of captive and wild tamarins (Saguinus spp.) [PDF]

open access: yes, 2012
The colour vision polymorphism of most New World primates is a model system to study the function of colour vision. Theories for the evolution of primate trichromacy focus on the efficient detection and selection of ripe fruits and young leaves amongst ...

Comparison of forest regeneration in two sites with different primate abundances in Northwestern Ecuador [PDF]

open access: yes, 2016
There is increasing evidence that large-bodied primates play important roles as seed dispersers and in the maintenance of tree diversity in forest ecosystems. In this study we compared forest regeneration at two sites with differing primate abundances in

Dispersal in male ursine colobus monkeys (Colobus vellerosus): Influence of age, rank and contact with other groups on dispersal decisions [PDF]

open access: yes, 2011
Dispersal is male-biased in ursine colobus monkeys (Colobus vellerosus), although female dispersal also occurs (Teichroeb et al., 2009). Here we describe the process of male dispersal and its connection with between-group encounters (BGEs, N = 444) and ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Figs Are More Than Fallback Foods: The Relationship between Ficus and Cebus in a Tropical Dry Forest

open access: yesInternational Journal of Zoology, 2011
In many studies on primate feeding ecology, figs (Ficus spp.) are characterized as fallback foods, utilized only when preferred sources of food are unavailable. However, for white-faced capuchin monkeys (Cebus capucinus) living in northwestern Costa Rica,

The Evolution of Primate Societies - Chapter 3 [PDF]

open access: yes, 2012
Compared with other primates, New World monkeys display relatively limited ecological variability. New World monkey anatomy and social systems, however, are extremely diverse.

Demographic buffering in natural populations: A multi‐level perspective

open access: yesJournal of Animal Ecology, EarlyView.
We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Individualistic female dominance hierarchies with varying strength in a highly folivorous population of black-and-white colobus [PDF]

open access: yes, 2013
Females that do not experience strong contest competition for food are presumed to form egalitarianâ relationships (i.e., lacking strong, linear dominance hierarchies).

Forest structure and connectivity drive the functional recovery of seed rain

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.

Prehensile Tail Use in Mantled Howler Monkeys (Alouatta palliata) and White-Faced Capuchin Monkeys (Cebus capucinus) [PDF]

open access: yes, 2016
The prehensile tail, present in five platyrrhine genera, has evolved in parallel in Ateles, Lagothrix, Brachyteles, and Alouatta, comprising the atelines, and Cebus.
