Data from: Context dependent colonization dynamics: regional reward contagion drives local compression in aquatic beetles

Matthew R. Pintar & William J. Resetarits
1. Habitat selection by colonizing organisms is an important factor in determining species abundance and community dynamics at multiple spatial scales. Many organisms select habitat patches based on intrinsic patch quality, but patches exist in complex landscapes linked by dispersal and colonization, forming metapopulations and metacommunities. Perceived patch quality can be influenced by neighboring patches through spatial contagion, wherein perceived quality of one patch can extend beyond its borders and either increase or decrease the...

Data from: The role of climatic and geological events in generating diversity in Ethiopian grass frogs (genus Ptychadena)

Megan L. Smith, Brice P. Noonan & Timothy J. Colston
Ethiopia is a world biodiversity hotspot and harbours levels of biotic endemism unmatched in the Horn of Africa, largely due to topographic—and thus habitat—complexity, which results from a very active geological and climatic history. Among Ethiopian vertebrate fauna, amphibians harbour the highest levels of endemism, making amphibians a compelling system for the exploration of the impacts of Ethiopia's complex abiotic history on biotic diversification. Grass frogs of the genus Ptychadena are notably diverse in Ethiopia,...

Data from: Stalk formation of Brevundimonas and how it compares to Caulobacter crescentus

Patrick D. Curtis
The Caulobacter crescentus cell extension known as a stalk represents an unusual bacterial morphology. C. crescentus produces stalks under multiple nutrient conditions, but the length of the stalk is increased in response to phosphate starvation. However, the exact function of the stalk is not known, nor is it known how much stalk biogenesis or function is conserved with other stalked bacteria. Work presented here shows that many organisms in the Caulobacter genus and the next...

Data from: Drosophila increase exploration after visually detecting predators

Miguel Del La Flor, Lijian Chen, Claire Manson-Bishop, Tzu-Chun Chu, Kathya Zamora, Danielle Robbins, Gemunu Gunaratne, Gregg Roman & Miguel De La Flor
Novel stimuli elicit behaviors that are collectively known as specific exploration. These behaviors allow the animal to become more familiar with the novel objects within its environment. Specific exploration is frequently suppressed by defensive reactions to predator cues. Herein, we examine if this suppression occurs in Drosophila melanogaster by measuring the response of these flies to wild harvested predators. The flies used in our experiments have been cultured and had not lived under predator threat...

Data from: Theory, practice, and conservation in the age of genomics: the Galápagos giant tortoise as a case study

Hgh-throughput DNA sequencing allows efficient discovery of thousands of single nucleotide polymorphisms (SNPs) in non-model species. Population genetic theory predicts that this large number of independent markers should provide detailed insights into population structure, even when only a few individuals are sampled. Still, sampling design can have a strong impact on such inferences. Here, we use simulations and empirical SNP data to investigate the impacts of sampling design on estimating genetic differentiation among populations that...
