Data from: Context-dependent expression of the foraging gene in field colonies of ants: the interacting roles of age, environment and task

Krista K. Ingram, Deborah M. Gordon, Daniel A. Friedman, Michael Greene, John Kahler & Swetha Peteru
´┐╝Task allocation among social insect workers is an ideal framework for studying the molecular mechanisms underlying behavioural plasticity because workers of similar genotype adopt different behavioural phenotypes. Elegant laboratory studies have pioneered this effort, but field studies involving the genetic regulation of task allocation are rare. Here, we investigate the expression of the foraging gene in harvester ant workers from five age- and task-related groups in a natural population, and we experimentally test how exposure...

Data from: On the widespread capacity for and functional significance of extreme inbreeding in ferns

Emily B. Sessa, Weston L. Testo, & James E. Watkins
Homosporous vascular plants utilize three different mating systems, one of which, gametophytic selfing, is an extreme form of inbreeding only possible in homosporous groups. This mating system results in complete homozygosity in all progeny and has important evolutionary and ecological implications. Ferns are the largest group of homosporous land plants, and the significance of extreme inbreeding for fern evolution has been the subject of debate for decades. We cultured gametophytes in the laboratory and quantified...
