Data for: Range reshuffling: climate change, invasive species, and the case of Nothofagus forests in Aotearoa New Zealand

Aim: The impact of climate change on forest biodiversity and ecosystem services will be partly determined by the relative fortunes of invasive and native forest trees under future conditions. Aotearoa New Zealand has high conservation value native forests and one of the world's worst invasive tree problems. We assess the relative effects of habitat redistribution on native Nothofagus and invasive conifer (Pinaceae) species in New Zealand as a case study on the compounding impacts of climate change and tree invasions. Location: Aotearoa New Zealand Methods: We use species distribution models (SDMs) to predict the current and future distribution of habitat for five native Nothofagus species and 13 invasive conifer species under two 2070 climate scenarios. We calculate habitat loss/gain for all species and examine overlap between the invasive and native species now and in the future. Results: Most species will lose habitat overall. The native species saw large changes in the distribution of habitat with extensive losses in North Island and gains mostly in South Island. Concerningly, we found that most new habitat for Nothofagus was also suitable for at least one invasive species. However, there were refugia for the native species in the wetter parts of the climate space. Main conclusion: If the predicted changes in habitat distribution translate to shifts in forest distribution it would cause widespread ecological disruption. We discuss how acclimation, adaptation and biotic interactions may delay some changes. But we also highlight how the poor migration and establishment capacity of native Nothofagus and the competitive ability of invasive conifers will be a persistent conservation challenge in areas of both new habitat and forest retreat. Pinaceae are problematic invaders globally, and our results highlight that control of invasions and active native forest restoration will likely be key to managing forest biodiversity under future climates.

Datasets for: Climate change and conservation of Caladenia orchids in Western Australia

Occurence data for 26 Caladenia species for the paper: "Climate change and conservation of Caladenia orchids in Western Australia"  Abstract Understanding how species distributions are being shaped by current rises in atmospheric temperature is of immediate conservation importance. Orchids are a globally threatened plant family, with many species having narrow ranges and low abundances that heighten extinction risk due to rising atmospheric temperature. Using 26 rare and common Caladenia orchid species in Western Australia, we first performed a conservation assessment by calculating the proportion of populations that currently occur in conservation areas. We then compared current range extents with past and future climate scenarios. We performed a niche overlap test with a future climate scenario to test how the current population level climatic niche of these species will change. As some of these orchids frequently hybridize, we then quantified how ecogeographical isolation will change under future climates. Only 27% of all Caladenia populations are currently found in protected areas. Most species had reduced range extents in historically warmer climates. However, only three species will experience range extent contractions under future climate scenarios. The current population climatic niche has a 36% overlap with future climates, indicating that current population level conditions may change. Ecogeographical isolation will potentially increase in hybridizing species, thereby acting as a stronger barrier against hybridization. As Caladenia species evolved in seasonally dry conditions, this suggests that there is potential preadaptation to survive under elevated temperatures. Despite their physiological tolerances to elevated temperature, conservation of Caladenia species will depend on the availability of habitat to allow migration within future range limits, and the presence of their key mutualists.

Climate stressors are also increasingly affecting access to subsistence resources. Within Inuit communities, people differ in their involvement with subsistence activities, but little is known about how engagement in the cash economy (time and money available) and other socio-economic factors shape the food production choices of Inuit harvesters, and their ability to adapt to rapid ecological change. We analyse 281 foraging trips involving 23 Inuit harvesters from Kangiqsujuaq, Nunavik, using a Bayesian approach modelling both patch choice and within-patch success. Gender and income predict Inuit harvest strategies: while men, especially men from low-income households, often visit patches with a relatively low success probability, women and high-income hunters generally have a higher propensity to choose low-risk patches. Inland hunting, marine hunting, and fishing differ in the required equipment and effort, and hunters may have to shift their subsistence activities if certain patches become less profitable or less safe due to high costs of transportation or climate change (e.g., navigate larger areas inland instead of targeting seals on the sea ice). Our finding that household income predicts patch choice suggests that the capacity to maintain access to country foods depends on engagement with the cash economy.

Data from: Climate change alters global invasion vulnerability among ecoregions

Aim: We assess climate similarity among global freshwater and terrestrial ecoregions under historical and future climate scenarios to determine where climate change will impact the climate filter of invasion process. Location: Global. Methods: We used the Climatch algorithm to conduct a climate-match analysis to quantify the climate similarity between freshwater and terrestrial ecoregions of the world. Climate match was modelled between all freshwater and terrestrial ecoregions. The analysis was conducted under historical climates and projected climates of 2090 under three shared-socioeconomic pathways SSP2-4.5, SSP3-7.0, SSP5-8.5. Climate matches of each ecoregion were presented as mean climate match to all other ecoregions. Friedman's non-parametric rank sum two-way analysis of variance with repeated measures was used to examine differences in climate match between climate scenarios.

Genomic vulnerability of a freshwater salmonid under climate change

Understanding the adaptive potential of populations and species is pivotal for minimizing the loss of biodiversity in this era of rapid climate change. Adaptive potential has been estimated in various ways, including based on levels of standing genetic variation, presence of potentially beneficial alleles, and/or severity of environmental change. Kokanee salmon, the non-migratory ecotype of sockeye salmon (Oncorhynchus nerka), is culturally and economically important, and has already been impacted by the effects of climate change. To assess its climate vulnerability moving forward, we integrated analyses of standing genetic variation, genotype-environment associations and climate modeling based on sequence and structural genomic variation from 224 whole genomes sampled from 22 lakes from British Columbia and Yukon (Canada). We found that variables for extreme temperatures, particularly warmer temperatures, had the most pervasive signature of selection in the genome and were the strongest predictors of levels of standing variation and of putatively adaptive genomic variation, both sequence and structural. Genomic offset estimates, a measure of climate vulnerability, were significantly correlated with higher increases in extreme warm temperatures, further highlighting the risk of summer heat waves that are predicted to increase in frequency in the future. Levels of standing genetic variation, an important metric for population viability and resilience, were not correlated with genomic offset. Nonetheless, our combined approach highlights the importance of integrating different sources of information and genomic data to formulate more comprehensive and accurate predictions on the vulnerability of populations and species to future climate change.
