Data from: Colonization history, host distribution, anthropogenic influence and landscape features shape populations of white pine blister rust, an invasive alien tree pathogen

Simren Brar, Clement K. M. Tsui, Braham Dhillon, Marie-Josée Bergeron, David L. Joly, P. J. Zambino, Yousry A. El-Kassaby & Richard C. Hamelin
White pine blister rust is caused by the fungal pathogen Cronartium ribicola J.C. Fisch (Basidiomycota, Pucciniales). This invasive alien pathogen was introduced into North America at the beginning of the 20th century on pine seedlings imported from Europe and has caused serious economic and ecological impacts. In this study, we applied a population and landscape genetics approach to understand the patterns of introduction and colonization as well as population structure and migration of C. ribicola....

Data from: Can butterflies evade fire? Pupa location and heat tolerance in fire prone habitats of Florida

Matthew D. Thom, Jaret C. Daniels, Leda N. Kobziar & Jonathan R. Colburn
Butterflies such as the atala hairstreak, Eumaeus atala Poey, and the frosted elfin, Callophrys irus Godart, are restricted to frequently disturbed habitats where their larval host plants occur. Pupae of these butterflies are noted to reside at the base of host plants or in the leaf litter and soil, which may allow them to escape direct mortality by fire, a prominent disturbance in many areas they inhabit. The capacity of these species to cope with...

Data from: More than one way to evolve a weed: Parallel evolution of U.S. weedy rice through independent genetic mechanisms

Xinshuai Qi, Yan Liu, Cynthia C. Vigueira, Nelson D. Young, Ana L. Caicedo, Yulin Jia, David R. Gealy & Kenneth M. Olsen
Many different crop species were selected for a common suite of ‘domestication traits’, which facilitates their use for studies of parallel evolution. Within domesticated rice (Oryza sativa), there has also been independent evolution of weedy strains from different cultivated varieties. This makes it possible to examine the genetic basis of parallel weed evolution and the extent to which this process occurs through shared genetic mechanisms. We performed comparative QTL mapping of weediness traits using two...
