Data from: Genetic variation and structure in the neotropical tree, Manilkara zapota (L) P. Royen (Sapotaceae) used by the ancient Maya

K. M. Thompson, Theresa M. Culley, A. M. Zumberger & D. L. Lentz
Manilkara zapota is a tropical tree species that was used by the ancient Maya in construction of their temples and as a source for fruit. Although this has been supported by ethnographic and paleoethnobotanical data, we used genetic approaches to estimate variation and structure in modern populations of this neotropical tree species to discern if genetic patterns were consistent with earlier influences of ancient Maya management or if they could be explained by the natural...

Data from: An examination of fitness costs of glyphosate resistance in the common morning glory, Ipomoea purpurea

Catherine L. Debban, Sara Okum, Kathleen E. Pieper, Ariana Wilson & Regina S. Baucom
Fitness costs are frequently invoked to explain the presence of genetic variation underlying plant defense across many types of damaging agents. Despite the expectation that costs of resistance are prevalent, however, they have been difficult to detect in nature. To examine the potential that resistance confers a fitness cost, we examined the survival and fitness of genetic lines of the common morning glory, Ipomoea purpurea, that diverged in the level of resistance to the herbicide...

Data from: An empirical review: characteristics of plant microsatellite markers that confer higher levels of genetic variation

Benjamin J. Merritt, Theresa M. Culley, Alina Avanesyan, Richard Stokes & Jessica Brzyski
During microsatellite marker development, researchers must choose from a pool of possible primer pairs to further test in their species of interest. In many cases, the goal is maximizing detectable levels of genetic variation. To guide researchers and determine which markers are associated with higher levels of genetic variation, we conducted a literature review based on 6782 genomic microsatellite markers published from 1997–2012. We examined relationships between heterozygosity (He or Ho) or allele number (A)...

Data from: Geographic ranges of genera and their constituent species: structure, evolutionary dynamics, and extinction resistance

Michael Foote, Kathleen A. Ritterbush & Arnold I. Miller
We explore the relationships among the geographic ranges of genera, the ranges and positions of their constituent species, and the number of species they contain, considering variation among coeval genera and changes within genera over time. Measuring range size as the maximal distance, or extent, between occurrences within a taxon, we find that the range of the most widespread species is a good predictor of the range of the genus, and that the number of...
