In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

open access: yesThe Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Brown lemurs (Eulemur fulvus) can master the qualitative version of the reverse-reward contingency. [PDF]

open access: yesPLoS ONE, 2012
Behavioral flexibility that requires behavioral inhibition has important fitness consequences. One task commonly used to assess behavioral inhibition is the reverse-reward task in which the subject is rewarded by the non selected items.

Hominoid‐specific calretinin‐immunopositivity of the optic radiation (geniculocalcarine tract)

open access: yesThe Anatomical Record, EarlyView.
Calretinin‐immunostained coronal section through the primary (V1) and extrastriate (ExSt) cortex of the lar gibbon. Note that the optic radiation (OR) is strongly calretinin‐immunoreactive. This calretinin‐immunopositivity of the OR distinguishes the Hominoidea from other primates in terms of the neurochemistry of the OR.

Comparing the cost-effectiveness of methods for estimating population density for primates in the Amazon rainforest Peru [PDF]

open access: yes, 2015
With increasingly extreme fluctuations in flood levels in the Amazon basin (Malhi et al. 2008, Marengo et al. 2012, Bodmer et al. 2014) the future of its' fauna is becoming more uncertain.

Tactile information improves visual object discrimination in kea, Nestor notabilis, and capuchin monkeys, Sapajus spp. [PDF]

open access: yes, 2018
In comparative visual cognition research, the influence of information acquired by nonvisual senses has received little attention. Systematic studies focusing on how the integration of information from sight and touch can affect animal perception are ...

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

Mimivirus Circulation among Wild and Domestic Mammals, Amazon Region, Brazil

open access: yesEmerging Infectious Diseases, 2014
To investigate circulation of mimiviruses in the Amazon Region of Brazil, we surveyed 513 serum samples from domestic and wild mammals. Neutralizing antibodies were detected in 15 sample pools, and mimivirus DNA was detected in 9 pools of serum from ...

Global distribution and contexts of interactions between humans and non‐human primates: A systematic review

open access: yesPeople and Nature, EarlyView.
Abstract Understanding the frequency and socio‐ecological drivers of contacts between humans and non‐human primates (NHPs) is crucial for enhancing coexistence that favours NHP conservation, while limiting negative consequences such as aggressions and cross‐species disease transmission.

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.
