TL;DR: 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.

TL;DR: The honeydew produced in Homoptera shelters at study sites in east Texas could supply nearly one-half of the daily energetic requirements of an S. invicta colony, suggesting that Exploitative or mutually beneficial associations that occur between these insects may be an important, previously unrecognized factor promoting their success.

TL;DR: The experiment provides important insight into the effects of a common tritrophic interaction among an invasive mealybug, Antonina graminis, an invasive host grass, Cynodon dactylon L. Pers.

TL;DR: Sex‐ratio conflict between queens and workers was explored in a study of colony sex ratios, relatedness, and population investment in the ant Pheidole desertorum, and results are generally consistent with that study.

TL;DR: Analyses using an apparently unbiased alternative to body weight in estimating parental investment in solitary wasps support the hypothesis that actual covariance between sexual size dimorphism and the sex investment ratio will occur if mothers produce small males when those males compete primarily with brothers for access to mates.
