Topography constrains the climatic response of treeline migration in Taiwan's subalpine forests

Ecography, Volume 2026, Issue 9, September 2026.
Treelines are moving upslope, but the rates and drivers differ among different regions, globally. Many studies have examined the relationship between treeline movement and climate change, particularly rising temperature, while the role of topographical factors has received much less attention, despite the longstanding recognition of its importance.

Global threats, local opportunities: ice‐related landforms provide refugia for high‐elevation plants and arthropods

Ecography, Volume 2026, Issue 9, September 2026.
Ice‐related landforms in mountain areas have been hypothesized to play a key role in the survival of cold‐adapted species threatened by climate change. However, our understanding of such landforms acting as refugia remains speculative. Here we analyse occurrence data, collected through a standardized sampling at 471 sampling points across the European ...

Integrating multi‐decadal satellite imagery and species distribution models for conservation planning in oak woodlands

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Oak woodlands are among California's least protected yet most ecologically important ecosystems, providing critical habitat for a wide variety of plant and animal species. These foundational plant communities are increasingly threatened by drought, wildfire, and other climate‐driven disturbances, which have contributed to significant declines ...

Adaptations in Sphagnum functional traits in response to increased elevation in karst plateau wetlands

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Sphagnum functional traits serve as crucial indicators of environmental change and are essential for predicting potential alterations in wetland plant functions. However, there exists a significant knowledge gap concerning the response of Sphagnum functional traits and functions to elevation gradients in plateau wetlands. This study, therefore,
