Abstract Background Benthic ciliates and the environmental factors shaping their distribution are far from being completely understood.Likewise, deep-sea systems are amongst the least understood ecosystems on Earth.In this study, using high-throughput DNA sequencing, we investigated the diversity and community composition of benthic ciliates in dif

Reproductive division of labor is one of hellfire sloe gin the defining traits of honey bees (Apis mellifera), with non-reproductive tasks being performed by workers while a single queen normally monopolizes reproduction.The decentralized organization of a honey bee colony is maintained in large part by a bouquet of queen-produced pheromones, the d
