Data from: The interaction of exposure and warming tolerance determines fish species vulnerability to warming stream temperatures
Species vulnerability to climate change involves an interaction between the magnitude of change (exposure) and a species' tolerance to change. We evaluated fish species vulnerability to predicted stream temperature increases by examining warming tolerances across the Wyoming fish assemblage. Warming tolerance combines stream temperature with a thermal tolerance metric to estimate how much warming beyond current conditions a species can withstand. Brown trout, rainbow trout, and burbot had the lowest warming tolerances and highest proportion of currently occupied sites that will become unsuitable under predicted temperature increases. These most vulnerable species were coldwater species, but had neither the lowest thermal tolerances, nor would they experience the greatest temperature increases. Our results highlight the importance of considering the interaction of exposure and warming tolerance when predicting climate change vulnerability and demonstrate an approach that can be applied broadly.
Data from: Phylogeographic differentiation versus transcriptomic adaptation to warm temperatures in Zostera marina, a globally important seagrass
Populations distributed across a broad thermal cline are instrumental in addressing adaptation to increasing temperatures under global warming. Using a space-for-time substitution design, we tested for parallel adaptation to warm temperatures along two independent thermal clines in Zostera marina, the most widely distributed seagrass in the temperate Northern Hemisphere. A North–South pair of populations was sampled along the European and North American coasts and exposed to a simulated heatwave in a common-garden mesocosm. Transcriptomic responses under control, heat stress and recovery were recorded in 99 RNAseq libraries with ~13 000 uniquely annotated, expressed genes. We corrected for phylogenetic differentiation among populations to discriminate neutral from adaptive differentiation. The two southern populations recovered faster from heat stress and showed parallel transcriptomic differentiation, as compared with northern populations. Among 2389 differentially expressed genes, 21 exceeded neutral expectations and were likely involved in parallel adaptation to warm temperatures. However, the strongest differentiation following phylogenetic correction was between the three Atlantic populations and the Mediterranean population with 128 of 4711 differentially expressed genes exceeding neutral expectations. Although adaptation to warm temperatures is expected to reduce sensitivity to heatwaves, the continued resistance of seagrass to further anthropogenic stresses may be impaired by heat-induced downregulation of genes related to photosynthesis, pathogen defence and stress tolerance.
Data from: Recognizing cross-ecosystem responses to changing temperatures: soil warming impacts pelagic food webs
The energy and materials that move across ecosystem boundaries influence food web structure and key ecosystem functions. Despite the acknowledged importance of such ecological subsidies, surprisingly little information is available regarding the role of environmental temperature in influencing subsidy quality and the response of the recipient ecosystem. We evaluated the impacts of temperature-mediated changes in leaves from deciduous trees, an important subsidy from terrestrial to freshwater ecosystems, on both the producer-based and detritivore-based components of a pelagic pond food web in a field mesocosm experiment. We hypothesized that variation in leaf chemistry driven by increased soil temperature would alter both the quality of leaf subsidies and the pond response. We collected red maple Acer rubrum leaves from heated and ambient temperature plots from the long-term soil warming experiment at the Harvard Experimental Forest and added them to 167-l field mesocosms containing established plankton communities, creating 'no leaf', 'ambient leaf' and 'heated leaf' treatments during autumn 2012. We then monitored physical, chemical, and biological responses to treatments until the mesocosms froze six weeks later. Experimental soil warming altered the chemical composition of deciduous leaves, the physical and chemical environment of the aquatic ecosystems to which leaves were added, and the pelagic pond food webs as measured by community composition. Compared to leaves from ambient-temperature soils, leaves from warmed soils initially resulted in lower water column phosphorus and dissolved organic carbon, reducing bacterial densities. However, the diminished carbon and phosphorus resulting from soil warming also increased light availability that ultimately stimulated cladoceran zooplankton relative to ambient-temperature leaves. Our results suggest that changes in temperature can alter ecological subsidies in unanticipated ways, and suggest that accurately predicting the potential consequences of climate change will require conducting research across ecosystem boundaries.

Data for: Warming temperatures limit the maximum body length of teleost fishes across a latitudinal gradient in Norwegian waters
<p>As the majority of marine organisms are water-breathing ectotherms, temperature and dissolved oxygen are key environmental variables that influence their fitness and geographic distribution. In line with the gill-oxygen limitation theory (GOLT), the maximum asymptotic body size of water-breathing ectotherms is limited by an insufficient amount of oxygen that is supplied to meet metabolic demand once a threshold of gill surface area to body weight ratio is surpassed. Here we employed generalised additive models (GAMs) to investigate the relative influence of temperature, regional variation in dissolved oxygen, and geographic location (that encompasses multiple latent variables) on the maximum body length of ten teleost fish species, as well to predict their maximum body length, across a large temperature, depth and latitudinal gradient throughout Norwegian waters. As dissolved oxygen levels were near saturation across the study area, we conclude that the predicted maximum lengths of our study species were not limited by oxygen availability. Conversely, the majority of study species display a clear relationship in that their predicted maximum length is either decreasing, asymptotic or parabolic across their observed temperature range. We also observed smaller maximum body lengths for multiple species within the coldest extent of their temperature range, which may be explained by increases in basal metabolism via cold denaturation. Overall, our results suggest that the maximum lengths of our study species are influenced by temperature, thus supporting the tenants of the GOLT.</p>
Effects of temperature on seed dormancy and germination of the coastal dune plant Viola grayi: Germination phenology and responses to winter warming
<p>PREMISE: In temperate sand dunes, rising air temperature owing to climate change could not only further elevate surface soil temperatures during summers but also drastically change the range of soil temperatures in other seasons. Winter warming may shift the timing of seed germination of dune species that require cold stratification for dormancy release.</p> <p>METHODS: We assessed the effects of temperature on dormancy and germination of <i>Viola grayi</i> seeds and evaluated whether winter warming could affect its germination phenology by conducting germination experiments and analyzing soil temperature data in cold and warm winters.</p> <p>RESULTS: <i>Viola grayi</i> seeds were dormant when dispersed in spring. One-month moist-chilling treatment (4°C) effectively released dormancy, while short, intermittent lower temperatures (alternating 20/5°C) did not. Continuous higher temperatures induced secondary dormancy in non-dormant seeds. During a cold, snowy winter, the surface soil temperatures of the sand dune remained at 0–2°C for approximately one month owing to the accumulated snow, while the period of such stable low soil temperatures was much shorter during a warm, less snowy winter, and the highest soil temperature class reached 20–25°C. These results suggest that dispersed seeds germinate in the following spring after winter chilling, but they may remain dormant after warm winters.</p> <p>CONCLUSIONS: With winter warming, prolonged seed dormancy and associated germination delay could occur in <i>V. grayi</i> seeds. Assessing the minimum requirements for dormancy release and the potential to form persistent soil seed banks is important for judging the necessity and urgency of conservation efforts for temperate dune species.</p>
Spring-flowering herbs in North American temperate forests advance their phenology more than trees with warming temperatures
<ol> <li>The phenologies of co-occurring trees and spring-blooming understory herbs in northeastern hardwood forests appear to be regulated by different environmental drivers—air temperature and soil temperature/snowpack, respectively. Accordingly, it has been hypothesized that climate change-driven asymmetry in the advancement of canopy leaf-out relative to the timing of understory growth could reduce photosynthetic rates and reproductive success of understory herbs through greater early-season shading.</li> <li>To determine whether trees and spring-flowering spring-flowering forest herbs are advancing their phenologies at different rates with respect to increasing global temperatures, we examined the phenological responses to warming of 10 species of trees and 11 species of spring-flowering forest herbs (8,045 observations from 965 sites) in northeastern North America using 13 years of data collected by citizen scientists under the auspices of the USA-National Phenology Network.</li> <li>Contrary to expectation, the timing of leaf-out of spring-flowering forest herbs was more strongly associated with temperature than was timing of tree leaf-out, with a mean response rate of −4.9 days/˚C (95% BCI [−5.2, −4.6]) for spring-flowering forest herbs <em>vs.</em> −3.3 days/℃ (95% BCI [−3.5, −3.1]) for trees. However, the response to temperature was not consistent across the latitudinal range, with spring-flowering forest herbs responding more strongly to warming than trees at middle (40–44˚N) and higher (45–48˚N) latitudes but not at lower latitudes (35–39˚N). </li> <li>In contrast to what has been suggested previously, our results suggest that the growing season and carbon uptake of spring-flowering forest herbs could increase as spring temperatures rise. Our study is the first to show spring-flowering forest herbs advancing their phenology at a higher rate than trees with respect to warming.</li> </ol>
Data from: Northern range expansion of European populations of the wasp spider Argiope bruennichi is associated with global warming correlated genetic admixture and specific temperature adaptations
Poleward range expansions are observed for an increasing number of species, which may be an effect of global warming during the past decades. However, it is still not clear in how far these expansions reflect simple geographical shifts of species ranges, or whether new genetic adaptations play a role as well. Here, we analyse the expansion of the wasp spider Argiope bruennichi into Northern Europe during the last century. We have used a range-wide sampling of contemporary populations and historical specimens from museums to trace the phylogeography and genetic changes associated with the range shift. Based on the analysis of mitochondrial, microsatellite and SNP markers, we observe a higher level of genetic diversity in the expanding populations, apparently due to admixture of formerly isolated lineages. Using reciprocal transplant experiments for testing overwintering tolerance, as well as temperature preference and tolerance tests in the laboratory, we find that the invading spiders have possibly shifted their temperature niche. This may be a key adaptation for survival in Northern latitudes. The museum samples allow a reconstruction of the invasion's genetic history. A first, small-scale range shift started around 1930, in parallel with the onset of global warming. A more massive invasion of Northern Europe associated with genetic admixture and morphological changes occurred in later decades. We suggest that the latter range expansion into far Northern latitudes may be a consequence of the admixture that provided the genetic material for adaptations to new environmental regimes. Hence, global warming could have facilitated the initial admixture of populations and this resulted in genetic lineages with new habitat preferences.

Data from: Mutualisms in a warming world—how increased temperatures affect the outcomes of multi-mutualist interactions
<p><span>In nature, plant species simultaneously interact with many different mutualistic partners. These mutualists may influence one another through direct interference or indirectly by competing for shared reward resources or through alteration of plant traits. Together, these mutualists also may combine to affect plant hosts in ways that may not be predictable based on pairwise</span><span> int</span><span>eractions. </span><span>Given that the outcome of mutualistic interactions often depends on environmental conditions, multi-mutualist effects on one another and their plant hosts may be affected by global changes. Here, we grew focal plants under simulated global warming conditions and manipulated the presence of partner mutualists to test how warming affects the outcome of interactions between focal plants and their partners (nitrogen-fixing rhizobia, ant defenders, and pollinators) and interactions among these partner mutualists. We find that </span><span>warming alters the fitness benefits plants receive from rhizobium resource mutualists but not ant mutualists and that warming altered plant investment in all mutualists. We also find that mutualist partners interact, often by altering the availability of plant-produced rewards that facilitate interactions with other partners. Our work illustrates that global changes may affect some but not all mutualisms, often asymmetrically (e.g., affecting investment in the mutualist partner but not plant host benefits) and also highlights the ubiquity of interactions between the multiple mutualists associating with a shared host.</span></p>
Permafrost response to temperature rise in carbon and nutrient cycling: Effects from habitat-specific conditions and factors of warming
<p>Permafrost is warming at a rate of two times faster than the rest of the Earth's surface. However, there is still a lack of a quantitative basis for predicting the functional stability of permafrost ecosystems in carbon (C) and nutrient cycling. We compiled the data of 708 observations from 89 air-warming experiments in the Northern Hemisphere and characterized the general effects of temperature increase on permafrost C exchange and balance, biomass production, microbial biomass, soil nutrients, and vegetation N dynamics via a meta-analysis. Also, an investigation was made on how responses may change with habitat-specific (e.g., plant functional groups and soil moisture status) conditions and warming variables (e.g., warming phases, levels, and timing). Warming downregulated net ecosystem C exchange generally via stimulating ecosystem respiration (15.6%) more than photosynthesis (6.2%). Vegetation usually responded to warming by investing more the C to the belowground, as belowground biomass increased much more (30.1%) than aboveground biomass (2.9%). Warming had a minor effect on microbial biomass. Warming increased soil ammonium and nitrate concentrations. What's more, a synthesis of 70 observations from 11 herbs and 9 shrubs revealed a 2.5% decline of N in green leaves. Compared to herbs, shrubs demonstrated a stronger response in respiration and had green leaf N declined by a greater extent. Not only in dry conditions did green leaf N decline with warming but also in wet conditions. Warming in non-growing seasons would negatively affect soil water, C uptake, and biomass production during growing seasons. Permafrost C loss and vegetation N decline may increase with warming levels and timing. Overall, our findings suggest that besides a positive C cycling-climate feedback, there will be negative feedback between permafrost nutrient cycling and climate warming.</p>
Data from: Role of horizontal temperature advection in Arctic surface warming in early spring
<p><span>Extreme Arctic warming scenario is studied with an idealized numerical experiment of polar warming. We employ the Community Earth System Model version 1.0 (CESM1.0) in this study. The control starts from the rest of the data with standard configurations (using a CO<sub>2</sub> concentration of 285 ppm). Overall, the model climate reaches a quasi-equilibrium state after 1,000 years of integration (Yang et al., 2015). A surface albedo perturbation experiment (0.1A) is carried out to achieve global warming and AA. During years 1501-2000, 0.1A is "parallel" to control, with the same initial conditions at the end of year 1500, and it reaches quasi-equilibrium after the 500-year integration. In the numerical result study, we focus on the equilibrium responses using the monthly averaged fields over the last 200 years of integration. Here we offered SAT anomaly, 500 hPa geopotential height, surface wind anomaly, and surface horizontal heat advection anomaly.</span></p>
