TLDR
A genetical mathematical model is described which allows for interactions between relatives on one another's fitness and a quantity is found which incorporates the maximizing property of Darwinian fitness, named “inclusive fitness”.About:

Genetic diversity within honeybee colonies prevents severe infections and promotes colony growth.
TL;DR: Honeybees investigated to determine whether genetic variation helps to prevent chronic infections, and it is shown that genetically diverse colonies had a lower variance in disease prevalence than genetically similar colonies, suggesting that genetic diversity may benefit colonies by preventing severe infections.

TL;DR: The study indicates that heterogeneity in aspirations may be key for the sustainability of cooperation in structured populations and finds that for sufficiently positive values of there exist a robust intermediate for which cooperation thrives best.

The adaptive significance of avian mobbing: II. Cultural transmission of enemy recognition in blackbirds: Effectiveness and some constraints.
TL;DR: The “Cultural Transmission Hypothesis” and the “Alerting Others Hypot hypothesis” of enemy recognition in birds was examined in mobbing experiments with captive blackbirds and strength of the observer's enhanced response was comparable to that elicited by a genuine predator.

TL;DR: It is found that males were the most frequent attackers and victims; most killings involved intercommunity attacks; and attackers greatly outnumbered their victims (median 8:1 ratio).

Book
Animal dispersion in relation to social behaviour
TL;DR: Wynne-Edwards has written this interesting and important book as a sequel to his earlier (1962) Animal Dispersion in Relation to Social Behaviour, and reviewing it has proven to be a valuable task for one who normally is only at the periphery of the group selection controversy.
