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>
"The sound comes from a meadow in the Sierra Nevada Mountains in California. The meadow is at an elevation of 2400 meters near a mountain named Olancha Peak, which is 3700 meters in altitude. Ihave a group of friends with which Ibackpack (trek) into the mountains. Our goal was to spend some time in the mountains and hike to the top of Olancha Peak (…) By the time we reached the meadow, we were in a forest and there was still snow on the ground in some places. We took the trip in June of 2006. The Sierra Nevada Mountains are a large mountain range. Much of the range is protected by national parks or preserved areas we call 'wilderness areas' (…) Ihave been backpacking for nearly 40 years and Iwill hopefully continue with this challenging activity for 40 years more! Many of my friends are much younger than Iam and it gives me much satisfaction to be able to have as much or more stamina for this activity than they have! When we are on these trips, we hike up peaks, catch fish, drink some whiskey around campfires and enjoy our time in the beautiful solitude. My memories of this trip were of the steep, hot hike from the desert to the cool meadow; the overall beauty of the nature, the absolute solitude of our campsite near the meadow; the strenuous hike to the top of Olancha Peak; the camaraderie of my friends; and, of course the sound of the frogs in the meadow. The frog sounds were astounding to me and Iwould listen in awe of the creature's instinctual desire to reproduce and continue the existence of their kind. Surely there were different species in the meadow for some of the frog sounds were different than others. The sounds only occurred after the Sun went down for the evening. Istood next to the creek in the meadow and recorded the sounds using my digital camera." [Peter/plentz1960]16 in Collecting Sounds. Online Sharing of Field Recordings as Cultural Practice

Dataset Mother-offspring conflict for water varies across altitude and is mitigated in the oviparous form of the bimodal lizard Zootoca vivipara
<p>The female dataset provides the responses of gravid and non reproductive female common lizard to a two week period of water restriction. This includes the measures of body mass (BM) and plasma osmolality (osmo) at the onset and the end of this timing. Dataset also reports different information on reproductive performance and characteristics of the population they came from. </p> <p>The juvenile dataset provides the morphological (snout-vent length: SVL, body mass: BM) and the sex of hatchling. We also included information about mother identity (cltuch effect), mother treatment and the characteristics of populations they came from. </p>
Data from: Altitude difference might contribute to the genetic divergence of giant panda' staple food Bamboo (Fargesia spathacea complex) based on 14 SSR markers
<p>The taxonomy in woody bamboo faces a lot of difficulties due to its long blooming intervals and complicated morphological variation. Whether the current taxonomy would reflect the genuine species divergence within woody bamboo is an intriguing question. <i>Fargesia spathacea</i> complex comprises fifteen closely related species with sympatric distribution in China. Their classification has long been controversy because of only a handful of vegetative traits available, thus providing a good opportunity to explore the evolutionary relationship and genetic differentiation in woody bamboo. Here we presented a study with 750 individuals from 39 representative populations in <i>Fargesia spathacea</i> complex using 14 SSR markers. We found varying degrees of genetic diversity across populations of the <i>Fargesia spathacea</i> complex (<i>He</i>=0.07-0.81) and largely negative <i>F</i> values at the population level, implying an excess of heterozygotes in the populations. Phylogenetic analyses revealed that all populations were divided into two major groups (cluster A and B), with the majority of fifteen species representing distinct genetic lineages. Based on the population genetic analysis along with morphological evidence, we confirmed the identity of three species (<i>F. decurvata</i>, <i>F. spathacea</i> and <i>F. murielae</i>) and suggested invalidation of four other species (<i>scabrida</i>, <i>F. robusta</i>, <i>F. denudata</i> and <i>F. nitida</i>). The delimitation of the rest eight species was yet to be explored. The ecological factor and spatial autocorrelation analysis supported that altitude difference might account for the distinct genetic divergence between two major groups.</p>
