Ecological patterns of root nodule diversity in cultivated and wild rooibos populations: a community prediction approach

Josep Ramoneda, Jaco Le Roux, Emmanuel Frossard, Beat Frey & Hannes Andres Gamper
There is interest in understanding the factors behind the biogeography of root-associated bacteria due to the joint effects that plant host, climate, and soil conditions can have on bacterial diversity. For legume crops with remaining wild populations, this is of even more importance, because the effects of cropping on undisturbed root-associated bacterial communities can be addressed. Here, we used a community prediction approach to describe the diversity of the root nodule bacterial communities of rooibos...

Genomic evidence for correlated trait combinations and antagonistic selection contributing to counterintuitive genetic patterns of adaptive diapause divergence in Rhagoletis flies

McCall Calvert, Meredith Doellman, Jeffrey Feder, Glenn Hood, Peter Meyers, Scott Egan, Thomas Powell, Mary Glover, Cheyenne Tait, Hannes Schuler, Stewart Berlocher, James Smith, Patrik Nosil, Dan Hahn & Gregory Ragland
Adaptation to novel environments often results in unanticipated genomic responses to selection. Here, we illustrate how multifarious, correlational selection helps explain a counterintuitive pattern of genetic divergence between the recently derived apple- and ancestral hawthorn-infesting host races of Rhagoletis pomonella (Diptera: Tephritidae). The Apple host race terminate diapause and emerge as adults earlier in the season than the hawthorn host race to coincide with the earlier fruiting phenology of their apple hosts. However, alleles at...

Data from: Evidence for spatial clines and mixed geographic modes of speciation for North American cherry-infesting Rhagoletis (Diptera:Tephritidae) flies

An important criterion for understanding speciation is the geographic context of population divergence. Three major modes of allopatric, parapatric, and sympatric speciation define the extent of spatial overlap and gene flow between diverging populations. However, mixed modes of speciation are also possible, whereby populations experience periods of allopatry, parapatry, and/or sympatry at different times as they diverge. Here, we report clinal patterns of variation for 21 nuclear-encoded microsatellites and a wing spot phenotype for cherry-infesting...
