Data from: Evolution of life history traits in geographically isolated populations of Vaejovis scorpions (Scorpiones: Vaejovidae)

Matthew M. Steffenson & Christopher A. Brown
Geographical isolation can over time accumulate life-history variation which can eventually lead to speciation. We used five species of Vaejovis scorpions that have been isolated from one another since the Pleistocene glaciation to identify if biogeographical patterns have allowed for the accumulation of life-history variation among species. Gravid females were captured and brought back to the lab until giving birth. Once offspring had begun to disperse, measurements of female size, reproductive investment, offspring size, offspring...

Data from: Diagnostic gene expression biomarkers of coral thermal stress

Gene expression biomarkers can enable rapid assessment of physiological conditions in situ, providing a valuable tool for reef managers interested in linking organism physiology with large-scale climatic conditions. Here, we assessed the ability of quantitative PCR (qPCR) based gene expression biomarkers to evaluate (1) the immediate cellular stress response (CSR) of Porites astreoides to incremental thermal stress and (2) the magnitude of CSR and cellular homeostasis response (CHR) during a natural bleaching event. Expression levels...

Data from: Genetic architecture of isolation between two species of Silene with sex chromosomes and Haldane's rule

Jeffery Paul Demuth, Rebecca J. Flanagan & Lynda F. Delph
Examination of the genetic architecture of hybrid breakdown can provide insight into the genetic mechanisms of commonly observed isolating phenomena such as Haldane’s rule. We used line-cross analysis to dissect the genetic architecture of divergence between two plant species that exhibit Haldane’s rule for male sterility and rarity, Silene latifolia and Silene diclinis. We made 15 types of crosses, including reciprocal F1, F2, backcrosses, and later-generation crosses, grew the seeds to flowering, and measured the...
