Data from: Variation in ecophysiological traits might contribute to ecogeographic isolation and divergence between parapatric ecotypes of Mimulus aurantiacus

James M. Sobel, Sean Stankowski & Matthew A. Streisfeld
Many forms of reproductive isolation contribute to speciation, and early acting barriers may be especially important, because they have the first opportunity to limit gene flow. Ecogeographic isolation occurs when intrinsic traits of taxa contribute to disjunct geographic distributions, reducing the frequency of inter‐taxon mating. Characterizing this form of isolation requires knowledge of both the geographic arrangement of suitable habitats in nature and the identification of phenotypes involved in shaping geographic distributions. In Mimulus aurantiacus,...

Data from: An alternative approach to reduce algorithm-derived biases in monitoring soil organic carbon changes

Quantifying soil organic carbon (SOC) changes is a fundamental issue in ecology and sustainable agriculture. However, the algorithm-derived biases in comparing SOC status have not been fully addressed. Although the methods based on equivalent soil mass (ESM) and mineral-matter mass (EMMM) reduced biases of the conventional methods based on equivalent soil volume (ESV), they face challenges in ensuring both data comparability and accuracy of SOC estimation due to unequal basis for comparison and using un-conserved...

Data from: Clothing color mediates lizard responses to humans in a tropical forest

Andrea Fondren, Lindsey Swierk & Breanna Putman
Identifying how ecotourism affects wildlife can lower its environmental impact. Human presence is an inherent component of ecotourism, which can impact animal behavior because animals often perceive humans as predators and, consequently, spend more time on human-directed antipredator behaviors and less on other fitness-relevant activities. We tested whether human clothing color affects water anole (Anolis aquaticus) behavior at a popular ecotourism destination in Costa Rica, testing the hypothesis that animals are more tolerant of humans...

Data from: Rapid and Repeatable Host Plant Shifts Drive Reproductive Isolation Following a Recent Human-Mediated Introduction of the Apple Maggot Fly, Rhagoletis pomonella

Glen R. Hood, Thomas H.Q. Powell, Doellman, Sheina B. Sim, Mary Glover, Wee L. Yee, Robert B. Goughnour, Monte Mattsson, Dietmar Schwarz & Jeffrey L. Feder
Ecological speciation via host-shifting is often invoked as a mechanism for insect diversification, but the relative importance of this process is poorly understood. The shift of Rhagoletis pomonella in the 1850s from the native downy hawthorn, Crataegus mollis, to introduced apple, Malus pumila, is a classic example of sympatric host race formation, a hypothesized early stage of ecological speciation. The accidental human-mediated introduction of R. pomonella into the Pacific Northwest (PNW) in the late-1970’s allows...

Data from: The effects of different cold-temperature regimes on development, growth, and susceptibility to an abiotic and biotic stressor

Matthew Wersebe, Paradyse Blackwood, Ying T. Guo, Jared Jaeger, Dyllan May, George Meindl, Sean N. Ryan, Vivian Wong & Jessica Hua
1. Global climate change is expected to both increase average temperatures as well as temperature variability. 2. Increased average temperatures has led to earlier breeding in many spring-breeding organisms. However, individuals breeding earlier will also face increased temperature fluctuations, including exposure to potentially harmful cold temperature regimes during early developmental stages. 3. Using a model spring-breeding amphibian, we investigated how embryonic exposure to different cold-temperature regimes (control, cold-pulse, and cold-press) affected (1) compensatory larval development...
