Data from: Hybridization, species collapse, and species reemergence after disturbance to premating mechanisms of reproductive isolation

Robert Tucker Gilman & Jocelyn Elyssa Behm
There are now a number of well-studied cases in which hybridization between closely related sympatric species has increased, sometimes resulting in the replacement of species pairs by hybrid swarms. Many of these cases have been linked to anthropogenic environmental change, but the mechanisms leading from environmental change to species collapse, and the long-term effects of hybridization on species pairs, remain poorly understood. We used an individual-based stochastic simulation model to explore the conditions under which...

Data from: Identification of X-linked quantitative trait loci affecting cold tolerance in Drosophila melanogaster and fine-mapping by selective sweep analysis

Nicolas Svetec, Annegret Werzner, Ricardo Wilches, Pavlos Pavlidis, José M. Álvarez-Castro, Karl W. Broman, Dirk Metzler & Wolfgang Stephan
Drosophila melanogaster is a cosmopolitan species that colonizes a great variety of environments. One trait that shows abundant evidence for naturally segregating genetic variance in different populations of D. melanogaster is cold tolerance. Previous work has found quantitative trait loci (QTL) exclusively on the second and the third chromosomes. To gain insight into the genetic architecture of cold tolerance on the X chromosome and to compare the results with our analyses of selective sweeps, a...

Data from: Pumping ions: rapid parallel evolution of ionic regulation following habitat invasions

Carol Eunmi Lee, Michael Kiergaard, Gregory William Gelembiuk, Brian Donovan Eads & Marijan Posavi
Marine to freshwater colonizations constitute among the most dramatic evolutionary transitions in the history of life. This study examined evolution of ionic regulation following saline-to-freshwater transitions in an invasive species. In recent years, the copepod Eurytemora affinis has invaded freshwater habitats multiple times independently. We found parallel evolutionary shifts in ion-motive enzyme activity (V-type H+ ATPase, Na+/K+-ATPase) across independent invasions and in replicate laboratory selection experiments. Freshwater populations exhibited increased V-type H+ ATPase activity in...

Emergency services utilization in Jakarta (Indonesia): A cross-sectional study of patients attending hospital emergency departments - data

Syaribah Noor Brice, Justin J Boutilier, Aryono Djuned Pusponegoro, Asti Puspita Rini & Paul Harper
The data were collected from five hospitals in Jakarta from December 1st to 31st 2019. There are 1964 data points representing participants included in the survey. The hospitals’ names were anonymous. The questionnaire gathered information on the patients’ demographic profile, medical conditions, reasons on choosing the transport and hospital, and the timing of the events involved in the patients’ journey to the emergency department. The patients’ age was numerical and measured in year, and all...
