Renewed interest in fission‐fusion dynamics is due to the recognition that such dynamics
may create unique challenges for social interaction and distinctive selective pressures acting …

The social organization of spider monkeys (Ateles geoffroyi) and chimpanzees (Pan troglodytes)
appear remarkably similar. In this paper, field studies of these two species were used to …

Many types of biological studies require the estimation of food abundance in tropical forests,
and a variety of methods have been used to estimate this parameter. Here we compare the …

The lives lost and economic costs of viral zoonotic pandemics have steadily increased over
the past century. Prominent policymakers have promoted plans that argue the best ways to …

Research in animals and humans has associated Alzheimer’s disease (AD) with decreased
cerebrospinal fluid levels of insulin in combination with decreased insulin sensitivity (insulin …

In this article we use new data to review the major threats facing primate populations and
assess probable declines and local extinctions. Subsequently, we outline some of the …

Detailed studies of primates and fruiting trees have illustrated that these groups of organisms
are involved in a very complex set of interactions, with primates relying on fruiting trees as …

The genetic algorithm, a search and optimization technique based on the theory of natural
selection, is applied to problems of structural topology design. An overview of the genetic …

We have developed a model that reconciles information-sharing and producer-scrounger
models of group foraging. Our model includes producers, scroungers, and an opportunistic …

Tropical forests and the animals they support are being threatened by accelerating rates of
forest conversion and degradation. In a continually fluctuating sociopolitical world, it is often …
