TLDR
An antithesis to the view that gregarious behaviour is evolved through benefits to the population or species is presented, and simply defined models are used to show that even in non-gregarious species selection is likely to favour individuals who stay close to others.About:

Cooperative breeding in marmots
TL;DR: This paper identifies cooperative breeding when: individuals delay dispersal beyond reproductive maturity, reproduction in mature individuals is suppressed, and when non-breeders provide alloparental care, and notes that marmots provide an excellent taxon in which to study the evolution of cooperative breeding.

Some causes of the variable shape of flocks of birds.
TL;DR: It is hypothesised that variability of shape increases when there are larger local differences in movement behaviour in the flock, and this is investigated with the help of a model of the self-organisation of travelling groups, called StarDisplay, since such a model has increased the understanding of what causes the oblong shape of schools of fish.

Social ethology of the whiptail wallaby, Macropus parryi, in northeastern New South Wales
TL;DR: In accordance with the whiptail's unaggressive nature, threat and submissive displays were less well developed than superiority and courtship displays and conflict activities, and whiptails are the most diurnal macropod.

Fish school density and volume
TL;DR: Extensive data is presented from experiments on cruising schools of saithe, herring and cod to validate the whole-school method and derive a computation which eliminates bias from outliers.

The survival value of flocking in neotropical birds: reality or fiction?
Mathilde Jullien,Jean Clobert +1 more
TL;DR: This work gathered published and unpublished data from various tropical forests where bird species forage exclusively alone or in pairs, in heterospecific flocks some of the time (facultative flock members), or exclusively in heterOSpecific year-long associations (obligate flock members) and tested whether survival rates differed among these three groups.

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.
