Harnessing social media data to track species range shifts

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs and citizen science data remain heavily biased toward the Global North. Especially in megadiverse countries with limited biodiversity records, incorporating social media data can help address existing data gaps.

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.

Use of species’ responses to cryptic anthropogenic disturbances for monitoring biodiversity outcomes in tropical forests

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract Measuring area‐based conservation outcomes in tropical forests is challenging due to cryptic human disturbances (e.g., hunting). As a result, comparative studies of management strategies providing quantitative outcomes remain scarce, especially in the Neotropics.

东祁连山高寒草甸土壤酶活性及其化学计量特征对海拔和坡向的响应

open access: yesShuitu Baochi Xuebao, 2022
研究高寒草甸微尺度海拔和坡向下土壤酶活性及其化学计量特征的变化对于探讨草地生态系统养分循环过程具有重要的生态学意义。以东祁连山高寒草甸为研究对象,分析了7个海拔(2 800,3 000,3 200,3 400,3 600,3 800,4 000 m)和2个坡向(阴坡、阳坡)高寒草甸的土壤酶活性、化学计量特征变化规律及其与土壤理化因子之间的关系。结果表明:海拔和坡向的交互效应对土壤亮氨酸氨基肽酶(LAP)、β-葡萄糖苷酶(BG)、多酚氧化酶(PPO)和过氧化物酶(POD)酶活性、lnBG/ln (NAG ...

The existing states and evolution of P and Fe in shallow sediments from the continental slope of northern South China Sea and their indication for the decomposition of gas hydrate [PDF]

open access: yes, 2016
天然气水合物作为当前极具开发潜力的新型清洁能源,受到科学界的广泛关注。海平面下降、洋壳的构造运动、海底沉积物滑塌及洋底水温变化等都可能造成天然气水合物的失稳分解,分解释放的CH4在垂向运移过程中与上层电子受体发生AOM,使SMTZ等作用带磷铁的赋存形态发生变化。磷作为海洋生物的重要营养元素,在海洋生物地球化学循环中有着重要意义,与铁、硫元素及沉积有机质关系紧密,在早期成岩过程中扮演了重要角色;而铁作为地壳中丰度最高的氧化还原敏感性金属元素,在海洋沉积物中的氧化还原过程对磷、硫 ...

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 ...
