Habitat and climatic associations of climate-sensitive species along a southern range boundary
<p><span class="Dummy">Climate change and habitat loss are recognized as important drivers of shifts in wildlife species' geographic distributions. While often considered independently, there is considerable overlap between these drivers, and understanding how they contribute to range shifts can predict future species assemblages and inform effective management. Our objective was to evaluate the impacts of habitat, climatic, and anthropogenic effects on the distributions of climate‐sensitive vertebrates along a southern range boundary <span>in Northern Michigan, USA</span>. We combined multiple sources of occurrence data, including harvest and citizen‐science data, then used hierarchical Bayesian spatial models to determine habitat and climatic associations for four climate‐sensitive vertebrate species (American marten [</span><em><span class="fi">Martes americana</span></em><span class="Dummy">], snowshoe hare [</span><em><span class="fi">Lepus americanus</span></em><span class="Dummy">], ruffed grouse [</span><em><span class="fi">Bonasa umbellus</span></em><span class="Dummy">], and moose [</span><em><span class="fi">Alces alces</span></em><span class="Dummy">]). We used total basal area of at‐risk forest types to represent habitat, and temperature and winter habitat indices to represent climate. Marten associated with upland spruce‐fir and lowland riparian forest types, hares with lowland conifer and aspen‐birch, grouse with lowland riparian hardwood</span><span>s</span><span>, </span><span class="Dummy">and moose with upland spruce‐fir. Species differed in climatic drivers with hares positively associated with cooler annual temperatures, moose with cooler summer temperatures, and grouse with colder winter temperatures. Contrary to expectations, temperature variables outperformed winter habitat indices. Model performance varied greatly among species, as did predicted distributions along the southern edge of the Northwoods region. As multiple species were associated with lowland riparian and upland spruce‐fir habitats, these results provide potential for efficient prioritization of habitat management. Both direct and indirect effects from climate change are likely to impact the distribution of climate‐sensitive species in the future and the use of multiple data types and sources in the modelling of species distributions can result in more accurate predictions resulting in improved management at policy‐relevant scales</span><span class="Dummy">.</span></p>

Supplemental data for: Parallel shifts in flight-height associated with altitude across incipient Heliconius species
<p class="MsoNormal"><span>Vertical gradients in microclimate, resource availability and interspecific interactions are thought to underly stratification patterns in tropical insect communities. However, only a few studies have explored the adaptive significance of vertical space use during the early stages of reproductive isolation. We analysed flight-height variation across speciation events in <em>Heliconius </em>butterflies representing parallel colonisations of high-altitude forest. We measured flight-height in wild <em>H. erato venu</em>s and <em>H. chestertonii</em>, parapatric lowland and mountain specialists respectively, and found that <em>H. chestertonii</em> consistently flies at a lower height. By comparing our data to previously published results for the ecologically equivalent <em>H. e. cyrbia</em> (lowland) and <em>H. himera </em>(high-altitude), we found that the species flying closest to the ground are those that recently colonised high-altitude forests. We show that these repeated trends largely result from shared patterns of ecological selection producing parallel trait-shifts in <em>H. himera </em>and <em>H. chestertonii</em>. Although our results imply a signature of local adaptation, we did not find an association between resource distribution and flight-height in <em>H. e. venus</em> and <em>H. chestertonii</em>. We discuss how this pattern may be explained by variation in forest structure and microclimate. Overall, our findings underscore the importance of behavioural adjustments during early divergence mediated by altitude-shifts.</span></p>
