Spatial mismatch between wild bee diversity hotspots and protected areas

open access: yesConservation Biology, Volume 37, Issue 4, August 2023., 2023
Abstract Wild bees are critical for multiple ecosystem functions but are currently threatened. Understanding the determinants of the spatial distribution of wild bee diversity is a major research gap for their conservation. We modeled wild bee α and β taxonomic and functional diversity in Switzerland to uncover countrywide diversity patterns and ...

Rewilding in the face of climate change

open access: yesConservation Biology, Volume 35, Issue 1, Page 155-167, February 2021., 2021
Abstract Expansion of the global protected‐area network has been proposed as a strategy to address threats from accelerating climate change and species extinction. A key step in increasing the effectiveness of such expansion is understanding how novel threats to biodiversity from climate change alter concepts such as rewilding, which have underpinned ...

鄂西桑寄生植物多样性的海拔格局

open access: yes, 2020
桑寄生植物(桑寄生科)的分布与寄主选择性和生境相关。本研究沿海拔梯度(175~3106 m)设置3条样带共292个样方(20 m×20 m),调查了鄂西亚热带森林群落中桑寄生的分布,记录桑寄生植物多样性。结果表明:在研究区内共调查到7种桑寄生科植物,40种寄主植物;桑寄生植物分布的最低海拔是194 m,最高海拔是2011 m;物种多样性在海拔梯度上先上升后下降,相对集中分布在海拔600~1000 m范围内,呈现单峰分布格局;不同桑寄生科植物在不同寄主植物上的寄生强度不同,更偏好选择高大的落叶乔木作为寄主;

Phenology drives asymmetric responses of ecosystem productivity stability to warming and cooling

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2959-2971, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem productivity stability is a key indicator of ecosystem functioning under climate change, but the role of cooling periods in increasingly variable climates remains poorly resolved.

Pinus armandii ectomycorrhizas mobilize aluminium‐bound phosphorus via carboxylates along a subtropical altitudinal gradient

open access: yesJournal of Ecology, Volume 114, Issue 8, August 2026.
Ectomycorrhizal roots of Pinus armandii release more carboxylates than non‐mycorrhizal root segments, mobilizing Al‐bound inorganic P. Under the lowest available P conditions, they also secrete more phosphatase, promoting the mineralization of Al‐bound organic P.

Climbing to survive: Potential elevational shifts in warming risk for the Moltrecht's treefrog

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Low‐elevation populations of Zhangixalus moltrechti had higher thermal limits but lower warming tolerance than high‐elevation populations. Climate change is expected to expand high‐risk areas upslope, highlighting the need for emissions reduction and targeted habitat management.

Elevation, soil pH and calcium availability shape regional and local scale spatial patterns of PhoD gene abundance in tropical and subtropical forests

open access: yesFunctional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Functional Stability Despite Taxonomic Changes in Mixed‐Species Foraging Flock Participants Along an Elevational Gradient in Knuckles Montane Reserve, Sri Lanka 斯里兰卡纳克斯山地保护区 (Knuckles Montane Reserve) 海拔梯度上混合物种觅食群参与者的功能稳定性与分类变化

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 59-73, March 2026.
This research reveals the functional stability of mixed species foraging flocks (MSF) and their foraging height change with different taxonomic differences along the elevational gradient at Knuckles Montane Reserve, Sri Lanka. This offers new insights into how MSFs sustain with the elevational gradients supporting the altitudinal shifting species ...

Natural Regeneration Outperforms Active Restoration in Enhancing Biodiversity and Biomass Along an Altitudinal Gradient in Chinese Savanna Ecosystems 中国稀树灌草丛中自然恢复对生物多样性与生物量的提升效应优于人工恢复

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 491-502, September 2025.
The impact of various restoration strategies on biodiversity and biomass in degraded savannas was evaluated across different elevation gradients. Natural regeneration co‐benefits the increasing in biodiversity and biomass in savannas, while active restoration exhibits altitude‐dependent efficacy and lower biomass accumulation capacity.
