Wax on, wax off: Nest soil facilitates indirect transfer of recognition cues between ant nestmates
Social animals use recognition cues to discriminate between group members and non-members. These recognition cues may be conceptualized …

Sperm viability staining in ecology and evolution: potential pitfalls
Drosophila melanogaster seminal fluid can protect the sperm of other males
Many internally‐fertilizing animals produce seminal fluid which is transferred along with sperm during mating. Seminal fluid typically …
