“…This ensures continuously high levels of carbon sequestration. Furthermore, protecting areas hosting A. angustifolia is a paramount strategy for its long-term persistence and conservation [57].…”

“…Promoting the long-term regeneration of forests and conserving old growth may be particularly effective in reconciling multiple targets [13,59]. Another concerning issue is the predicted decrease in range of A. angustifolia due to climate change [60], which may limit its role as a nature-based climate solution, leading to several negative impacts on biodiversity and human well-being [57].…”

“…In conclusion, the bene ts of climate-oriented management must strike a balance between maximizing AGC and the requirements of biodiversity conservation [10,13] and human well-being [61] in order to achieve multiple objectives simultaneously. However, conservation and restoration actions are now imperative if the long-term persistence of A. angustifolia in landscapes is to be ensured under current global change scenarios [57].…”

Background Understanding the drivers of variations in carbon stocks is essential for developing the effective management strategies that contribute to mitigating climate change. Although a positive relationship between biodiversity and the aboveground carbon (AGC) has been widely reported for various Brazilian forest types, representing a win–win scenario for climate change mitigation, this association has not been commonly found in Brazilian subtropical forests. Therefore, in the present study, we aimed to evaluate the effects of Araucaria angustifolia populations, stand structure and species diversity in shaping AGC stocks in Brazilian subtropical mixed forests. We hypothesized that the effects on the AGC of stand structure and diversity would be mediated by A. angustifolia. We also evaluated the expectation of higher carbon stocks in protected forests as a result of their positive correlation with biodiversity conservation. Results We found that stand structure, followed by A. angustifolia population, played the most important role in shaping the AGC stock. Our hypothesis was partially confirmed, the direct and indirect effects of A. angustifolia on stand structure being found to have shaped the AGC. Similarly, our expectation was partially supported, with the higher AGC in the protected area being related not to diversity, but rather to the presence of larger trees, denser stands, and a greater abundance of A. angustifolia. Conclusion Although the win–win strategy between diversity conservation and carbon storage is not a peculiarity of Araucaria forests, we highlight the potential of these forests as a nature-based climate solution, maintaining high levels of carbon storage in harmony with the provision of keystone resources.

AimTo provide an assessment of climate change impacts on a set of wild pollinators restricted to one of the regions with the greatest diversity of bees in the world. Also, we aimed to test whether functional groups responded differently to climate projections.LocationSouth‐eastern South America (SES).TaxonBees (Hymenoptera: Apidae sensu lato).MethodsWe selected 18 species of bees mostly restricted to the SES region, modelled their distributions and assessed the possible impacts of near future (2050) climate change in species richness and shifts in range centroids. Potential impacts related to different functional groups were evaluated through t‐tests.ResultsSES species richness was projected to decrease in the northernmost regions and increase southward. Most bee species were predicted to shift their range centroids towards the south‐west and south, while suitable stable areas were found in southern Brazil. We also found higher proportional losses in suitable areas for eusocial species compared to solitary ones, while generalists showed slightly lower gains than specialists.Main ConclusionSES bees are likely to undergo changes in the near future, with projected losses of species at northern portions and southward increases. The identified stable areas in southern Brazil underscore the importance of conservation efforts in the region, particularly in natural grasslands – an endangered habitat with high bee diversity. Although our results suggest higher vulnerability for functional groups traditionally considered more resilient, it is essential to acknowledge that other factors, including habitat and mutualists availability, behavioural particularities, phenology and range size, must be determinants for the vulnerability of species to ongoing climate change.
