Diverse reproductive barriers in hybridising crickets suggests extensive variation in the evolution and maintenance of isolation. Evolutionary Ecology. DOI: 10.1007/s10682-012-9610-2 Data collectors: Thor Veen, Joseph Faulks, Frances Tyler, Jodie Lloyd For information on data collection and methods, contact Thor Veen (thorveen@gmail.com) The file '8_Gryllidae_barrier_overview.csv' contains the summary data of the reproductive barriers found in the Gryllidae as depicted in Figure 7. The first column is the genus and the second the species involved in the pairing. Each subsequent column represents a different barrier. The rows should be treated in pairs(2-3, 4-5, etc (including the header as a row)), as they each contain the data of one of two possible mixed-species crosses. The Latin name in each row refers to the female in such cross, the male is the other species in the pair. In the example below, the first row (excluding the header) contains the data on the female Allonemobius fasciatus x male A. socius cross and the second row for the female A. socius x male A. fasciatus cross. The code represent the type of barrier: 0 = a reproductive barrier 1 = a barrier but not certain 2 = no barrier 3 = gene flow enhances but not certain 4 = gene flow enhanced Example: Genus species Calling_song Calling_song_preference Allonemobius fasciatus 2 2 A. socius 2 2
