Old world monkey vocalization: adaptation to the local habitat?
Article Abstract:
Continuous selection of distortion resistance patterns has more strongly affected the physiology of vocal repertoire of the rain forest monkeys compared to that of the savanna monkeys. Twenty-one vocalizations of two species of savanna monkeys and two species of forest monkeys were relayed in the savanna habitat and rain forest. Distortions up to transmission distance of 12.5 m were strong in the two species and increased moderately with the increase in distance. Distortion was greater in savanna habitat compared to rain forests.

How to measure inclusive fitness, revisited
Article Abstract:
The idea of inclusive fitness in animals has had substantial percussions since its inception 30 years ago, but its empirical application remains restricted. The most difficult aspects of inclusive fitness to create and to gauge are are the future effects. Partial solutions to the problem of estimating indirect and direct future fitness components have been suggested. The application of dynamic optimization to give a complete lifetime accounting has been demonstrated. Methods of estimating inclusive fitness are uniting.

Activity patterns, habitat use and mortality risks of mangabey males living outside social groups
Article Abstract:
Research describing mortality factors for lone grey-cheeked mangabey males is presented. Radio tracking studies show that lone males have higher rates of mortality but not starvation compared with group males.
