The fate of Meconopsis species in the Tibeto-Himalayan region under future climate change
<p>High-mountain areas such as the Tibeto-Himalayan region (THR) host cold-adapted biota expected to be sensitive to anthropogenic climate change. <i>Meconopsis</i> is a representative endangered genus confined to alpine meadow or subnival habitats in the THR. To obtain occurrence data for <i>Meconopsis</i> species found in the THR and adjacent regions, we used records from the Chinese Virtual Herbarium (CVH: <a href="http://www.cvh.org.cn/"><span>http://www.cvh.org.cn/</span></a>), the Global Biodiversity Information Facility (GBIF: <a href="http://www.gbif.org/">http://www.gbif.org/</a>), and the published literature (He et al., 2019). We only used occurrence data collected after 1950, and removed duplicate records found within a 5-kilometer diameter. Our dataset for ten species of <i>Meconopsis </i>are the numbers of records per species ranging from 17 to 228. For these ten <i>Meconopsis</i> species, we identified potential future climate refugia and determined optimal routes for each species to disperse to the proposed refugia. Our results indicate that for the ten <i>Meconopsis</i> species the regions with low vulnerability to climate change in the THR are the central Qinghai-Tibet Plateau, the Hengduan Mountains (HDM), the eastern Himalayas, and the West Qinlin Mountain (WQL), and can be considered potential future climate refugia. Under future climate change, we found for the ten <i>Meconopsis</i> species potential dispersal routes to three of the four identified refugia: the HDM, the eastern Himalayas, and the WQL. <i> </i>Furthermore, climate change may affect the threat ranking of Red Listed Species for <i>Meconopsis</i> species, as Least Concern species were estimated to become more vulnerable to climate change than the only Near Threatened species.</p>

Range expansion, habitat use and choosiness in a butterfly under climate change: marginality and tolerance of oviposition site selection
<p>Poleward range shifts under climate change involve the colonization of new sites and hence the foundation of new populations at the expanding edge. We studied oviposition site selection in a butterfly under range expansion (<i>Lycaena dispar</i>), a key process for the establishment of new populations. We described and compared the microhabitats used by the species for egg laying with those available across the study sites both in edge and in core populations. We carried out an ecological niche factor analysis (ENFA) to estimate (1) the variety of microhabitats used by the butterfly for egg laying (tolerance) and (2) the extent to which these selected microhabitats deviated from those available (marginality). Microhabitat availability was similar in edge and core populations. Ambient temperature recorded at the site level above the vegetation was on average lower at core populations. In contrast with what is often assumed, edge populations did not have narrower microhabitat use compared to core populations. Females in edge populations even showed a higher degree of generalism: they laid eggs under a wider range of microhabitats. We suggest that this pattern could be related to an overrepresentation of fast deciding personalities in edge populations. We also showed that the thermal time window for active female behaviour was reduced in edge populations, which could significantly decrease the time budget for oviposition and increase the threshold of acceptance during microhabitat selection for oviposition in recently established populations.</p>
Variation in intraspecific demography drives localised concordance but species-wide discordance in responses to Plio-Pleistocene climatic change
<p>Understanding how species biology may facilitate resilience to climate change remains a critical factor in detecting and protecting species at risk of extinction. Many studies have focused on the role of particular ecological traits in driving species responses, but less so on demographic history and levels of standing genetic variation. We used environmental and genomic datasets to reconstruct the phylogeographic histories of two ecologically similar and largely co-distributed freshwater fishes to assess the degree of concordance in their responses to Plio-Pleistocene climatic changes. Although several co-occurring populations demonstrated concordant demographic histories, idiosyncratic population size changes were found at the range edges of the more spatially restricted species. Discordant responses between species were associated with low standing genetic variation in peripheral populations. This might have hindered adaptive potential, as documented in recent population declines and extinctions of the two species. Our results highlight both the role of spatial scale in the degree of concordance in species responses to climate change, and the importance of standing genetic variation in facilitating range shifts. Even when ecological traits are similar between species, long-term genetic diversity and historical population demography may lead to discordant responses to ongoing and future climate change</p>
Shape of species climate performance curves affects community response to climate change
<p>Understanding how community composition is reshaped by changing climate is important for interpreting and predicting patterns of community assembly through time or across space. Community composition often does not perfectly correspond to expectations from current environmental conditions, leading to community-climate mismatches. Here, we combine data analysis and theory development to explore how species climate response curves affect the community response to climate change. We show that strong mismatches between community and climate can appear in the absence of demographic delays or limited species pools. Communities simulated using species response curves showed temporal changes of similar magnitude to those observed in natural communities of fishes and plankton, suggesting no overall delays in community change despite substantial unexplained variation from community assembly and other processes. Our approach can be considered as a null model that will be important to use when interpreting observed community responses to climate change and variability.</p>

Effects of future climate change on the forests of Madagascar
<p>Global climate change is continuing to occur at an alarming rate. In addition to increases in global weather extremes, melting of polar ice caps and subsequent sea level-rises, climate change is known to directly impact the life-cycles and ecologies of many animals and plants. Whilst climate change is projected to result in substantial geographic range and habitat contractions for many species in the future, the effects of climate change on many habitats of conservation-concern remain poorly understood. In this study, we investigated how future climate change is projected to impact the occurrence and distribution of four major forest types of Madagascar, a global biodiversity hotspot and conservation priority, over the next 60 years. We also compared how climate change effects vary among the four forest types under a "mitigation" climate forecast, and under a "business-as-usual" trajectory. As expected, our models suggest that future climate change will affect the distribution of the four forest types under both trajectories, and forest occurrence is likely to decrease if mean temperatures, temperature seasonality, and precipitation rates increase as predicted. The exception being that forest gain is predicted to occur in the north-west of Madagascar, resulting in a small increase in transitional forest area under the "business-as-usual" climate change trajectory. Our study highlights that unmitigated climate change will have a negative impact on Madagascar's forests during the period up to the year 2080, and climate change therefore needs to be mitigated. Madagascar remains a global conservation priority, and urgent conservation action and protective legislation is required to safeguard the future of its native forest.</p>
Climate oscillations drive millennial-scale changes in seabird colony size
<p>Seabird population size is intimately linked to the physical, chemical, and biological processes of the oceans. Yet, the overall effects of long-term changes in ocean dynamics on seabird colonies are difficult to quantify. Here, we used dated lake sediments to reconstruct ~10,000-years of seabird dynamics in the Northwest Atlantic to determine the influences of Holocene-scale climatic oscillations on colony size. On Baccalieu Island (Newfoundland and Labrador, Canada) – where the world's largest colony of Leach's storm-petrel (<em>Hydrobates leucorhous</em> Vieillot 1818) currently breeds – our data track seabird colony growth in response to warming during the Holocene Thermal Maximum (ca. 9,000 to 6,000 BP). From ca. 5,200 BP to the onset of the Little Ice Age (ca. 550 BP), changes in colony size were correlated to variations in the North Atlantic Oscillation (NAO). By contrasting the seabird trends from Baccalieu Island to millennial-scale changes of storm-petrel populations from Grand Colombier Island (an island in the Northwest Atlantic that is subjected to different ocean climate), we infer that changes in NAO influenced the ocean circulation, which translated into, among many things, changes in pycnocline depth across the Northwest Atlantic basin where the storm-petrels feed. We hypothesize that the depth of the pycnocline is likely a strong bottom-up control on surface-feeding storm-petrels through its influence on prey accessibility. Since the Little Ice Age, the effects of ocean dynamics on seabird colony size have been altered by anthropogenic impacts. Subsequently, the colony on Baccalieu Island grew at an unprecedented rate to become the world's largest resulting from favourable conditions linked to climate warming, increased vegetation (thereby nesting habitat), and attraction of recruits from other colonies that are now in decline. We show that although ocean dynamics were an important driver of seabird colony dynamics, its recent influence has been modified by human interference.</p>
