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 ...

Finding floral and faunal species richness optima among active fire regimes. [PDF]
Conserv BiolAbstract Changing fire regimes have important implications for biodiversity and challenge traditional conservation approaches that rely on historical conditions as proxies for ecological integrity. This historical‐centric approach becomes increasingly tenuous under climate change, necessitating direct tests of environmental impacts on biodiversity.

How to prioritize species recovery after a megafire. [PDF]
Conserv Biol, 2022 Abstract Due to climate change, megafires are increasingly common and have sudden, extensive impacts on many species over vast areas, leaving decision makers uncertain about how best to prioritize recovery. We devised a decision‐support framework to prioritize conservation actions to improve species outcomes immediately after a megafire.

Global effects of forest modification on herpetofauna communities. [PDF]
Conserv Biol, 2023 Abstract As the area covered by human‐modified environments grows, it is increasingly important to understand the responses of communities to the novel habitats created, especially for sensitive and threatened taxa. We aimed to improve understanding of the major evolutionary and ecological processes that shape the assemblage of amphibian and reptile ...

A landscape-scale framework to identify refugia from multiple stressors. [PDF]
Conserv Biol, 2022 Abstract From a conservation perspective, quantifying potential refugial capacity has been predominantly focused on climate refugia, which is critical for maintaining the persistence of species and ecosystems. However, protection from other stressors, such as human‐induced changes in fire and hydrology, that cause habitat loss, degradation, and ...

Software for prioritizing conservation actions based on probabilistic information. [PDF]
Conserv Biol, 2021 Abstract Marxan is the most common decision‐support tool used to inform the design of protected‐area systems. The original version of Marxan does not consider risk and uncertainty associated with threatening processes affecting protected areas, including uncertainty about the location and condition of species’ populations and habitats now and in the ...

Jianzhu Gangjiegou Jinzhan对于局部火灾，需要考虑建筑物构件在不均匀受热情况下的热学与力学响应。以方钢管梁为研究对象，模拟其不同高度处承受底部火羽流冲击作用的热力学现象。不同于应用绝热表面温度概念来实现流固传热的单向迭代耦合，提出一种新的计算流体力学-有限元数值（computational fluid dynamics-finite element method，CFD-FEM）模拟手段，通过采用CFD方法统一分析火灾模块与热模块来实现流固传热界面的双向直接耦合。首先通过典型局部火灾试验验证了该数值方法的准确性 ...

Jianzhu Gangjiegou Jinzhan火灾下轴心受压约束钢构件的力学响应复杂，所产生的温度内力导致其承载失效的确定与计算难度大。为简化基于结构构件高温承载极限状态的约束钢构件抗火设计方法，采用有限元数值模拟方法开展了大规模参数分析，以确定火灾高温下轴心受压约束钢构件的承载与失效规律。基于试验验证的可靠有限元模型，研究了不同长细比、轴向约束刚度比和初始荷载比等参数对轴心受压约束钢构件火灾响应的影响。结果表明，上述参数均将显著影响约束钢构件的火灾响应，且当长细比较大、轴向约束刚度比较小、初始荷载比较大时 ...

Risk, Hazards &Crisis in Public Policy, Volume 14, Issue 4, Page 297-320, December 2023., 2023 Abstract Urban marketplace fires in Ghana are chronic, devasting in economic losses and disproportionately impacting informal sector workers. Yet, the scholarly works on urban disasters have focused on hydrometeorological and other man‐made disasters to the neglect of marketplace fires, particularly the challenges in risk communication between ...

Modeling mammal response to fire based on species’ traits
Conservation Biology, Volume 37, Issue 4, August 2023., 2023 Abstract Fire has shaped ecological communities worldwide for millennia, but impacts of fire on individual species are often poorly understood. We performed a meta‐analysis to predict which traits, habitat, or study variables and fire characteristics affect how mammal species respond to fire.
