Understanding the capacity of forests to adapt to climate change is of pivotal importance for conservation science, yet this is still widely unknown. This knowledge gap is particularly acute in high-biodiversity tropical forests. Here, we examined how tropical forests of the Americas have shifted community trait composition in recent decades as a response to changes in climate. Based on historical trait-climate relationships, we found that, overall, the studied functional traits show shifts of less than 8% of what would be expected given the observed changes in climate. However, the recruit assemblage shows shifts of 21% relative to climate change expectation. The most diverse forests on Earth are changing in functional trait composition but at a rate that is fundamentally insufficient to track climate change.

Resilience is a key feature of ecosystem dynamics reflecting a system's ability to resist and recover from environmental perturbations. Slowing down in the rate of recovery has been used as an early-warning signal for abrupt transitions. Recent advances in Earth observation (EO) vegetation data provide the capability to capture broad-scale resilience patterns and identify regions experiencing resilience loss.

Pteridophytes, encompassing ferns and fern allies, are integral components of terrestrial ecosystems worldwide. These vascular plants characterized by their spore-based reproduction, fulfil various ecological roles such as influencing biodiversity, soil stability, nutrient dynamics, and ecological succession. Similar to higher plants, pteridophytes too are known to have close symbiotic associations with a diverse array of microorganisms, including bacteria, fungi and actinomycetes.

High temperatures increase the sugar concentration of grape ( L.) berries, which can negatively affect the composition and quality of wine, and global climate change is expected to exacerbate this problem. Modifying the source-to-sink ratio of grapevines by selective pruning is a potential strategy to mitigate this.

Diels (Sapindaceae), a highly threatened maple endemic to the dry-hot valleys of the Yalong River in western Sichuan, China, represents a valuable resource for horticulture and conservation. This study presents the first chromosomal-scale genome assembly of (~626 Mb, 2 = 26), constructed using PacBio HiFi and Hi-C sequencing technologies. Comparative genomic analyses revealed significant recent genomic changes through rapid amplification of transposable elements, particularly long terminal repeat retrotransposons, coinciding with the dramatic climate change during recent uplift of the Hengduan Mountains.

Climate change is impacting river ecosystems, underlining the need for water management strategies to protect native species within these ecosystems. Here, we evaluate the impact of climate change and water management on the physiology of white sturgeon () in the Nechako River, British Columbia (Canada). Using the CEQUEAU hydrological-thermal model, we simulated daily water temperatures from 1980 to 2099 under two climate scenarios (SSP2-4.
