Effects of interactions between anthropogenic stressors and recurring perturbations on ecosystem resilience and collapse. [PDF]
Conserv Biol, 2023 Abstract Insights into declines in ecosystem resilience and their causes and effects can inform preemptive action to avoid ecosystem collapse and loss of biodiversity, ecosystem services, and human well‐being. Empirical studies of ecosystem collapse are rare and hampered by ecosystem complexity, nonlinear and lagged responses, and interactions across ...

Rewilding in the face of climate change. [PDF]
Conserv Biol, 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 ...

Framing the change and changing frames: Tensions in participative strategy development
Politics &Policy, Volume 51, Issue 1, Page 81-113, February 2023., 2023 Abstract Participative strategy development serves to integrate the interests and perspectives of multiple stakeholders involved in today's complex environmental challenges, aiming at a better‐informed strategy for tackling these challenges, increased stakeholder ownership, and more democratic decision making.

Zhejiang Daxue xuebao. Lixue ban, 2017 采用化学活化法将造纸污泥制备成活性炭，运用SEM、BET、EDS、FT-IR等常规表征技术分析其理化性质，再将制备的污泥活性炭作为催化剂，应用于催化臭氧氧化降解橙黄Ⅱ模拟染料废水，并考察不同因素对橙黄Ⅱ降解效果的影响，探究污泥活性炭催化臭氧氧化橙黄Ⅱ的反应机理.结果表明：(1)造纸污泥活性炭的理想制备条件为：原污泥与氯化锌质量比为1：2，活化时间为12 h，炭化温度为600 ℃，炭化时间为60 min.

Gongye shui chuli, 2020 以泥炭土为原料，利用3-巯丙基三甲氧基硅烷对其进行改性，研究了不同巯基量改性泥炭土对水中Hg2+的吸附动力学特征及等温吸附解吸过程，并探讨了吸附机理。结果表明：提高泥炭土中的巯基含量，可增大泥炭土对Hg2+的吸附量，且吸附平衡时间明显缩短。巯基改性泥炭土对Hg2+的吸附符合准二级动力学方程和Langmuir吸附等温方程，吸附后的解吸率均较低。其吸附机理主要是通过羟基、羰基等官能团对汞的络合吸附作用。

SCIENTIA SINICA Terrae泥炭性质是调控泥炭碳储存能力的关键因素, 然而, 受限于有限的高分辨率泥炭记录, 其全新世百年尺度变率尚不明确. 研究分析了中国东北和青藏高原东部地区泥炭地的两条年代际分辨率有机质干密度记录, 发现其在全新世期间具有显著的~1000a、~710a、~350a、~210a、~130a以及~500a周期, 对应主要的太阳活动周期. 同时, 有机质干密度与太阳辐射总量呈反相位关系——太阳活动增强时, 有机质干密度降低. 泥炭有机质干密度、太阳活动与亚洲夏季风强度的变化不仅具有相似的周期信号, 且相位变化同步,

Joint Extraction Method for Spatial Relations in Chinese Geological Texts
Earth and Space Science, Volume 12, Issue 8, August 2025.Abstract Extracting spatial relations of geological entities is an important prerequisite for achieving natural language processing tasks such as geological knowledge question answering and semantic search, and is an important means to achieve structural reconstruction of unstructured geological data.

An assessment of future rewilding potential in the United Kingdom
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Restoring ecosystems is an imperative for addressing biodiversity loss and climate change, and achieving the targets of the Kunming–Montreal Global Biodiversity Framework. One form of restoration, rewilding, may have particular promise but may also be precluded by requirements for other forms of land use now or in the future.

Global status, impacts, and management of rocky temperate mesophotic ecosystems
Conservation Biology, Volume 38, Issue 1, February 2024.Abstract The ecology and function of rocky temperate mesophotic ecosystems (TMEs) remain poorly understood globally despite their widespread distribution. They typically occur at 20–150 m (the limit of photosynthesis), and on rocky substratum they support rich benthic communities and mobile fauna.
