WRF Geographic Files for Cordillera Mountain Range Precipitation Experiments
<p>These WRF geographic files (in netcdf format) were used as input for experiments to evaluate the sensitivity of Tropical Cyclone precipitation to the height of the Cordillera Mountain Range in Luzon, Philippines. A total of six files are included, for two domains (d01 and d02) and three different orographic experiments (orig, redu, enha).</p> <p>These are provided to allow reproduction of the said sensitivity experiments.</p>
A pathogen's spatial range is not constrained by geographical features in the flax rust pathosystem
<p>In this study, we performed several transect surveys over the course of the 2021 summer field season to assess potential ecogeographical range determinants for Lewis flax (<em>Linum</em> <em>lewisii</em>) and its pathogen, flax rust (<em>Melamspora</em> <em>lini</em>), in the area surrounding the Rocky Mountain Biological Laboratory in Gothic, Colorado. Additionally, we used generalized additive models to examine the effects of host population density and metapopulation structure on disease presence and prevalence.</p>

Data from: Expressed mutational load increases towards the edge of a species' geographic range
There is no general explanation for why species have restricted geographic distributions. One hypothesis posits that range expansion or increasing scarcity of suitable habitat result in accumulation of mutational load due to enhanced genetic drift, which constrains population performance towards range limits and further expansion. We tested this hypothesis in the North American plant, Arabidopsis lyrata. We experimentally assessed mutational load by crossing plants of 20 populations from across the entire species range and by raising the offspring of within- and between-population crosses at five common garden sites within and beyond the range. Offspring performance was tracked over three growing seasons. The heterosis effect, depicting expressed mutational load, was increased in populations with heightened genomic estimates of load, longer expansion distance or long-term isolation, and a selfing mating system. The decline in performance of within-population crosses amounted to 80%. Mutation accumulation due to past range expansion and long-term isolation of populations in the area of range margins is therefore a strong determinant of population-mean performance, and the magnitude of effect may be sufficient to cause range limits.
Data from: A resurrection study reveals limited evolution of thermal performance in response to recent climate change across the geographic range of the scarlet monkeyflower
<p>Evolutionary rescue can prevent populations from declining under climate change, and should be more likely at high-latitude, "leading" edges of species' ranges due to greater temperature anomalies and gene flow from warm-adapted populations. Using a resurrection study with seeds collected before and after a seven-year period of record warming, we tested for thermal adaptation in the scarlet monkeyflower <i>Mimulus</i> <i>cardinalis</i>. We grew ancestors and descendants from northern-edge, central, and southern-edge populations across eight temperatures. Despite recent climate anomalies, populations showed limited evolution of thermal performance curves. However, one southern population evolved a narrower thermal performance breadth by 1.31 °C, which matches the direction and magnitude of the average decrease in seasonality experienced. Consistent with the climate variability hypothesis, thermal performance breadth increased with temperature seasonality across the species' geographic range. Inconsistent with performance trade-offs between low and high temperatures across populations, we did not detect a positive relationship between thermal optimum and mean temperature. These findings fail to support the hypothesis that evolutionary response to climate change is greatest at the leading edge, and suggest that the evolution of thermal performance is unlikely to rescue most populations from the detrimental effects of rapidly changing climate.</p>
