The high seroprevalence of simian immunodeficiency viruses (SIVs) in African green monkeys (AGMs) without immunological defects in their natural hosts has prompted consideration of SIV-infected AGMs as a model of apathogenic SIV infection. Study of the molecular mechanisms of SIVagm asymptomatic infection could thus provide clues for understanding the pathogenesis of human immunodeficiency viru...

The Machiavellian/Social Intelligence Hypothesis proposes that a complex social environment selected for advanced cognitive abilities in vertebrates. In primates it has been proposed that sophisticated social strategies like obtaining suitable coalition partners are an important component of social intelligence. Knowing the rank relationships between group members is a basic requirement for the...

Here we propose a scenario to simulate sign processing in virtual creatures inhabiting a world of predatory events. In order to infer the minimum organizational constraints for the design of our creatures, we examined the well-studied case of semiosis in East African vervet monkeys (Cercopithecus aethiops) and its possible neuroanatomical substrates. This approach allowed us to simulate a case ...

We propose, based on the Peircean semiotics and inspired by an ethological case, a methodology to simulate the emergence of symbolic predator-warning communication among artificial creatures in a virtual world of predatory events. In order to build a digital ecosystem, and infer the minimum organizational constraints for the design of our creatures, we examined the well-studied case of semiosis...

Labial cavities in vervet monkeys were filled with two luting cements and 2 control materials (negative and positive). Specimens were recovered and examined histo­ logically. There war little difference between the pulpal reactions to the 4 materials. The reactions to the two test materials (luting cements) are, in 28 and 56 day spec­ imens, not more severe than the reactions to the negative co...

Abstract This paper explores the significance of intelligent social behavior among non‐human animals for philosophical theories communication. Using alarm call system vervet monkeys as a case study, I argue that interpersonal communication (or what “minded communication”) can and does take place in absence production recognition communicative intentions. More generally, evolutionary theory prov...

Accommodative responses to intramuscular pilocarpine were determined in four surgically aniridic vervet monkeys, before and after eight weeks of daily unilateral topical treatment with echothiophate iodide. The echothiophate-treated eyes maintained maximum myopia during the treatment course. However, after echotiophate treatment was stopped and the refraction had returned to baseline, a subsen...
