Upon detecting a fatal infection using chemical cues, ants puncture the cuticle of sick brood and inject antimicrobial poison that disrupts the pathogen's life cycle and prevents it from reproducing, thus protecting the colony from disease.
High-resolution GPS data revealed a quadratic relationship between group size and movement, with vulturine guineafowl groups of intermediate size exhibiting the largest home-range size and greater variation in site use.
Poison acidified crops sanitize food and limit disease transmission while at the same time structuring the gut microbiota and thus contribute to the ecological and evolutionary success of formicine ants.
A field study coupled with a molecular analysis demonstrates that using hematophagous flies as 'flying syringes' could be used to investigate blood-borne pathogen diversity in wild vertebrates and act as an early detection tool of zoonotic pathogens.
Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
