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:

Microbes, herbivory and the evolution of social behavior☆☆☆
TL;DR: Herbivorous animals that digest plant structural tissues almost invariably depend on the fermentative activity of symbiotic populations of microbes, housed in the digestive tract, to degrade plant fiber, and must concurrently evolve behavioral adaptations that ensure contact between generations.

Ephemeral roosts and stable patches? A radiotelemetry study of communally roostings starlings
TL;DR: Radiotelemetry observations on 15 adult European Starlings (Sturnus vulgaris) during two roosting seasons (June-November) in central New Jersey indicate that individuals are more faithful to their "diurnal activity centers" (DACs) than to their communal roosted sites, contrast sharply with the model of stable roosts and ephemeral patches central to many current explanations of communal rosting.

Mixed-species shoals and the maintenance of a sexual-asexual mating system in mollies
Ingo Schlupp,Michael J. Ryan +1 more
TL;DR: Females can discriminate between conspecific and heterospecific females, so that heterOSpecific mate copying is not a result of mistaken identity in mollies.

Contributions of female oviposition patterns and larval behavior to group defense in conifer sawflies (hymenoptera: diprionidae)
TL;DR: In this article, the authors studied the effects of adult oviposition and larval interactions on the defensive potential of gregarious behavior in conifer sawflies, and found that female ovoposition patterns are influenced in part by the defensive benefits gained by offspring in large aggregations.

Tail Display in Two Species of Iguanid Lizards: A Test of the "Predator Signal" Hypothesis
TL;DR: Two closely related genera, Cophosaurus and Holbrookia, are particularly interesting in this regard because they include species that vary in population density (and possibly in the potential for social interaction) and tail display behavior and tail morphology in two closely related species.

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.
