“…Insect distributions are currently experiencing pronounced shifts in response to climate change (Lancaster, ; Sánchez‐Guillén, Muñoz, Rodríguez‐Tapia, Arroyo, & Córdoba‐Aguilar, ), and insects also exhibit altered physiological (Advani et al., ; Lancaster, Dudaniec, Hansson, & Svensson, ; Lancaster et al., ) and phenological trait changes (Arribas, Abellán, Velasco, Millán, & Sánchez‐Fernández, ; Sánchez‐Guillén et al., ) associated with range shifts. Aquatic and semi‐aquatic insects may be among the first organisms to suffer from ongoing climate change due to exposure to anthropogenic stressors (e.g., habitat degradation), and dependence on climate‐mediated water temperatures (Woodward, Perkins, & Brown, ).…”

Insect distributions are shifting rapidly in response to climate change and are undergoing rapid evolutionary change. We investigate the molecular signatures underlying local adaptation in the range-expanding damselfly, Ischnura elegans. Using a landscape genomic approach combined with generalized dissimilarity modelling (GDM), we detect selection signatures on loci via allelic frequency change along environmental gradients. We analyse 13,612 single nucleotide polymorphisms (SNPs), derived from restriction site-associated DNA sequencing (RADseq), in 426 individuals from 25 sites spanning the I. elegans distribution in Sweden, including its expanding northern range edge. Environmental association analysis (EAA) and the magnitude of allele frequency change along the range expansion gradient revealed significant signatures of selection in relation to high maximum summer temperature, high mean annual precipitation and low wind speeds at the range edge. SNP annotations with significant signatures of selection revealed gene functions associated with ongoing range expansion, including heat shock proteins (HSP40 and HSP70), ion transport (V-ATPase) and visual processes (long-wavelength-sensitive opsin), which have implications for thermal stress response, salinity tolerance and mate discrimination, respectively. We also identified environmental thresholds where climate-mediated selection is likely to be strong, and indicate that I. elegans is rapidly adapting to the climatic environment during its ongoing range expansion. Our findings empirically validate an integrative approach for detecting spatially explicit signatures of local adaptation along environmental gradients.

“…Disentangling the role of temperature increase in shaping biodiversity patterns, especially in mountain ecosystems, is a fundamental challenge of conservation biology [2,3,8]. Species respond at individual level [1,2] and there is a current knowledge gap for many taxonomic groups [31][32][33]49]. Projections of potential future species distributions along elevational gradients need high-resolution spatial data [83,100].…”

Mountain biodiversity is associated with rare and fragile biota that are highly sensitive to climate change. To estimate the vulnerability of biodiversity to temperature rise, long-term field data are crucial. Species distribution models are an essential tool, in particular for invertebrates, for which detailed information on spatial and temporal distributions is largely missing. We applied presence-only distribution models to field data obtained from a systematic survey of 5 taxa (birds, butterflies, carabids, spiders, staphylinids), monitored in the northwestern Italian Alps. We estimated the effects of a moderate temperature increase on the multi-taxa distributions. Only small changes in the overall biodiversity patterns emerged, but we observed significant differences between groups of species and along the altitudinal gradient. The effects of temperature increase could be more pronounced for spiders and butterflies, and particularly detrimental for high-altitude species. We observed significant changes in community composition and species richness, especially in the alpine belt, but a clear separation between vegetation levels was retained also in the warming scenarios. Our conservative approach suggests that even a moderate temperature increase (about 1 °C) could influence animal biodiversity in mountain ecosystems: only long-term field data can provide the information to improve quantitative predictions, allowing us to readily identify the most informative signals of forthcoming changes.

“…Anthropogenic climate change and associated extreme weather events are predicted to significantly alter species distributions and subsequently the composition of biological communities (Arribas, Abellán, Velasco, Millán, & Sánchez‐Fernández, ; Huey et al, ; Jenkins et al, ; Thomas, ). Rising temperatures might cause metabolic, behavioural or evolutionary change in species, or drive dispersal to climatically suitable areas (Parmesan, ; Reuman, Holt, & Yvon‐Durocher, ; Urban, Tewksbury, & Sheldon, ).…”

Aim Studies of climate change impacts on animal distributions typically consider only the direct impacts of a changing climate, under the assumption that future areas of suitable climate will otherwise remain ecologically suitable. Here we assess both the direct and indirect impacts of climate change on rain forest ant communities, where substantial shifts are projected to occur for both climate and habitat types. Location Australian Wet Tropics (AWT). Methods Generalized Dissimilarity Modelling was used to model turnover in the composition of ~300 rain forest ant species sampled at 150 sites across six mountains spanning five degrees of latitude. Ants were sampled within the leaf litter, on the litter surface and on tree trunks. By modelling the rate of turnover among sites, we determined the current effective area of similar ecological environments (SEE) for ant communities and consequently the expected change in species persistence when habitat shifts under two climate projections for the years 2035, 2055 and 2085. We compared results when SEE considered only the direct effects of a changing climate, with those when changes in habitat were also included. Results The rain forest ant communities modelled will lose a substantial proportion of SEE under both climate change scenarios. Under combined direct (changes in climate) and indirect (changes in rain forest habitat) impacts of climate change, >90% of the communities in the region were predicted to lose up to half their similar habitats compared with 50%–60% when only considering direct climate change impacts. The highest risk of reduction in area of SEE is projected in drier inland areas of the AWT, where profound compositional turnover is linked to dramatic changes in rain forest vegetation, including extensive conversion into savanna. Main conclusions Our findings emphasize the importance of incorporating habitat suitability into future projections of species turnover under a changing climate, particularly for habitats where vegetation structure is projected to undergo profound change.
