Data from: The evolutionary enigma of mixed mating systems in plants: occurrence, theoretical explanations, and empirical evidence

Carol Goodwillie, Susan Kalisz & Christopher G. Eckert
Mixed mating, in which hermaphrodite plant species reproduce by both self- and cross-fertilization, presents a challenging problem for evolutionary biologists. Theory suggests that inbreeding depression, the main selective factor opposing the evolution of selfing, can be purged with self-fertilization, a process that is expected to yield pure strategies of either outcrossing or selfing. Here we present updated evidence suggesting that mixed mating systems are frequent in seed plants. We outline the floral and pollination mechanisms...

Data from: Millipede taxonomy after 250 years: classification and taxonomic practices in a mega-diverse yet understudied arthropod group

Michael S. Brewer, Petra Sierwald & Jason E. Bond
BACKGROUND: The arthropod class Diplopoda is a mega-diverse group comprising >12,000 described millipede species. The history of taxonomic research within the group is tumultuous and, consequently, has yielded a questionable higher-level classification. Few higher-taxa are defined using synapomorphies, and the practice of single taxon descriptions lacking a revisionary framework has produced many monotypic taxa. Additionally, taxonomic and geographic biases render global species diversity estimations unreliable. We test whether the ordinal taxa of the Diplopoda are...

Data from: Correlated evolution of mating system and floral display traits in flowering plants and its implications for the distribution of mating system variation

Carol Goodwillie, Risa D. Sargent, Susan Kalisz, Richard H. Ree, David A. Moeller, Mario Vallejo-Marin, Christopher G. Eckert, Alice A. Winn, Elizabeth Elle, Monica A. Geber & Mark O. Johnston
Reduced allocation to structures for pollinator attraction is predicted in selfing species. We explored the association between outcrossing and floral display in a broad sample of angiosperms. We used the demonstrated relationship to test for bias against selfing species in the outcrossing rate distribution, the shape of which has relevance for the stability of mixed mating. Relationships between outcrossing rate, flower size, flower number and floral display, measured as the product of flower size and...

Data from: A multilocus perspective on phylogenetic relationships in the Namib darkling beetle genus Onymacris (Tenebrionidae)

Trip Lamb & Jason E. Bond
Tenebrionid beetles, common constituent faunae of arid ecosystems worldwide, are particularly abundant in Africa’s Namib and Kalahari deserts. Within this region, flightless, diurnal members of the tribe Adesmiini are among the more intensively studied of all desert beetles, especially with regard to ecology. Much of this research centers on Onymacris, a psammophilous genus largely endemic to the Namib. Here we present the first molecular phylogenetic analysis conducted for Onymacris, emphasizing relationships among other adesmiines. Our...

Data from: Mate choice and the genetic basis for color variation in a polymorphic dart frog: inferences from a wild pedigree

Corinne L. Richards-Zawacki, Ian J. Wang & Kyle Summers
Understanding how reproductive barriers evolve during speciation remains an important question in evolution. Divergence in mating preferences may be a common first step in this process. The striking colour pattern diversity of strawberry dart frog (Dendrobates pumilio) populations has likely been shaped by sexual selection. Previous laboratory studies have shown that females attend to male coloration and prefer to court with males of their own colour, suggesting that divergent morphs may be reproductively isolated. To...
