Conflict resolution in insect societies.
Five major areas of reproductive conflict in insect societies are reviewed: (a) sex allocation, (b) queen rearing, (c) male rearing), (d) queen-worker caste fate, and (e) breeding conflicts among totipotent adults.
The ecology of the microbiome: Networks, competition, and stability
This finding indicates that hosts can benefit from microbial competition when this competition dampens cooperative networks and increases stability, and indicates that stability is promoted by limiting positive feedbacks and weakening ecological interactions.

A general model for the evolution of mutualisms
A general model predicts three key factors will be important in mutualism evolution and suggests that phenotypic feedbacks are a more important explanation for between‐species cooperation than the development of genetic correlations among species.
Cooperation and conflict in microbial biofilms
A detailed individual-based simulation of a biofilm is used to investigate the outcome of evolutionary competitions between strains that differ in their level of polymer production, suggesting that polymer secretion provides a strong competitive advantage to cell lineages within mixed-genotype biofilms: global cooperation is not required.
Low paternity in the hornet Vespa crabro indicates that multiple mating by queens is derived in vespine wasps

Low effective mating frequency in Vespa, in combination with data from other vespines, suggests that high paternity frequency is derived in the group, which is significantly biased with the majority male fathering on average 80% of the female offspring.
Emergence of Spatial Structure in Cell Groups and the Evolution of Cooperation
It is argued that cooperative and exploitative cell lineages will spontaneously segregate in space under a wide range of conditions and, therefore, that cellular cooperation may evolve more readily than naively expected.
The sociobiology of biofilms.
It is argued that understanding this balance between competition and cooperation is central to building a complete and predictive model of biofilm formation, and it is concluded that the appearance of organization in biofilms can emerge without active coordination.
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
