Object grasping and manipulation in capuchin monkeys (genera Cebus and Sapajus) [PDF]

open access: yes, 2018
The abilities to perform skilled hand movements and to manipulate objects dexterously are landmarks in the evolution of primates. The study of how primates use their hands to grasp and manipulate objects in accordance with their needs sheds light on how ...

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.

Short-Term Relocation Stress-Induced Hematological and Immunological Changes in Saimiri boliviensis boliviensis

open access: yesJournal of Immunology Research, 2021
Nonhuman primates are frequently transported to a new location or temporarily relocated within their colony. Both transportation and relocation expose animals to new environments, causing them to undergo a stress response (before adapting).

Undefining Man: A Case for Symbolic Animal Communication via Refutation of Kenneth Burke\u27s Definition of Man [PDF]

open access: yes, 2005
There have been tendencies in various fields to use communication as a way of differentiating humans and other species. Even when individuals are confronted with empirical evidence to the contrary, many still hold onto the notion that humans are in a ...

Ontological polyglossia: the art of communicating in opacity* Polyglossie ontologique : l'art de communiquer dans l'opacité

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
What do communicating with a baby, with an animal, and with an ancestor have in common? In all three cases, people engage in opaque communication that is far from the standard psycholinguistic model of transparent interaction based on shared intentionality.

Comparison of Blood and Brain Mercury Levels in Infant Monkeys Exposed to Methylmercury or Vaccines Containing Thimerosal [PDF]

open access: yes, 2005
Thimerosal is a preservative that has been used in manufacturing vaccines since the 1930s. Reports have indicated that infants can receive ethylmercury (in the form of thimerosal) at or above the U.S.

Mechanisms of Action and Targets of Nitric Oxide in the Oculomotor System [PDF]

open access: yes, 1998
Nitric oxide (NO) production by neurons in the prepositus hypoglossi (PH) nucleus is necessary for the normal performance of eye movements in alert animals.

Hedgehog Pillows and Squirrel Plates: Priming Semantic Structure in Children's Comprehension

open access: yesLanguage Learning, EarlyView.
Abstract We report three expression–picture‐matching experiments targeting preschoolers’ semantic processing. We assessed whether 3‐ and 4‐year‐olds’ interpretations of ambiguous novel noun–noun combinations (e.g., hedgehog pillow) were affected by immediate language experience and what role lexical items played in this process.

Involvement of Noradrenergic Neurotransmission in the Stress- but not Cocaine-Induced Reinstatement of Extinguished Cocaine-Induced Conditioned Place Preference in Mice: Role for β-2 Adrenergic Receptors [PDF]

open access: yes, 2010
The responsiveness of central noradrenergic systems to stressors and cocaine poses norepinephrine as a potential common mechanism through which drug re-exposure and stressful stimuli promote relapse.
