In the African mole-rat family (Bathyergidae), species show both year-round and seasonal breeding patterns even though all inhabit regions with varying rainfall (a well-known selection driver of breeding). This short review suggests a novel hypothesis explaining why some breed seasonally others year-round. Namely, group-living (with mean colony size greater than five) exhibit an aseasonal repro...
