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

open access: yesEcography, EarlyView.
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.

Sequencing of 50 human exomes reveals adaptation to high altitude

open access: yes, 2010
Residents of the Tibetan Plateau show heritable adaptations to extreme altitude. We sequenced 50 exornes of ethnic Tibetans, encompassing coding sequences of 92% of human genes, with an average coverage of 18x per individual.

Synergistic mechanisms foster declines in native fish community stability following the introduction of non‐native species

open access: yesEcography, EarlyView.
Non‐native species introductions profoundly alter freshwater communities, yet the mechanisms by which non‐native fishes affect native community stability remain unclear. Using a multi‐decadal dataset on fish community composition and abundance collected across France, we quantified native community stability and decomposed this metric into its main ...

Thermochromic Radiative Cooling Coatings with Robust Superhydrophobicity for Energy‐Efficient Buildings

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable, color‐adaptive radiative cooling coating is developed to enable dynamic spectral regulation via a reversible thermochromic transition at ~45 °C and a high solar reflectance of 91.7%. The coating achieves 4.44 °C outdoor sub‐ambient cooling while providing robust superhydrophobicity and environmental durability through its micro/nano ...

Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.
