Beewolf wasp eggs release nitrogen oxides to provide protection against fungi and other microbes.

A fish-derived bile salt was shown to act as interspecific infochemical, inducing the widespread predator avoidance behavior diel vertical migration at picomolar concentrations in freshwater zooplankton of the genus Daphnia.

The water flea Daphnia moves to deeper waters to avoid predators when it detects a chemical produced by fish.

To protect their food and themselves against detrimental mould fungi, the eggs of a wasp species synthesize and emit remarkable amounts of gaseous nitrogen oxides that are highly effective antimicrobials.

Whereas partner-serving phenotype is intuitively quantified as benefit release rate, molecular genetics revealed an example where this thinking fails, motivating a more general metric.

In richer, more even communities, foragers form broad categories among their food resources that can select for convergence among signals, including mimetic resemblances.

Organizational resilience allows ant colonies to retain high interaction rates in the face of decreased density by altering their spatial and social dynamics.

The most recent common ancestor of humans, chimpanzees, and bonobos possessed a foot adapted to terrestrial quadrupedalism and climbing.

Chemical nestmate recognition in honey bee colonies depends on an innate, socially modulated developmental process.

A molecular profiling approach to quantify transcripts and proteins from identical samples allows study of molecular effects of maturation, sexual differentiation and the endogenous circalunar clock in a marine worm.
