Understanding and Addressing the Disruptive Impacts of Contemporary Climate Crises

open access: yesJournal of Management Studies, EarlyView.
Abstract Contemporary climate crises, such as wildfires, droughts, floods, and tropical storms, are increasing in frequency, intensity, scale, and duration. Organization and management scholars have been calling for more systematic study of the impacts of this increasing complexity on extant crisis governance arrangements and capacities for ...

区域及全球尺度的NPP过程模型和NPP对全球变化的响应

open access: yes, 2014
植被净第一性生产力(NPP)不仅是表征植被活动和生态过程的关键参数,而且是判定生态系统碳汇和反映生态系统对全球变化响应的主要因子。当前,模型模拟成为大尺度NPP研究的主要手段,而在众多NPP估算模型中,过程模型逐渐趋于主导地位。虽然目前有关NPP的研究有很多,但还没有关注于大尺度上应用的过程模型及其模拟的NPP对全球变化的响应。因此本文主要侧重于NPP过程模型在区域及全球尺度上的应用,具体包含以下内容,①进一步将区域及全球尺度的NPP过程模型分为静态植被模型和动态植被模型 ...

Remembering Independence, Debating the Nation: Ghana's National Days

open access: yesNations and Nationalism, EarlyView.
ABSTRACT In Ghana, Independence Day is the most important national day and has been annually observed since the attainment of independence in 1957. Additional national days that various military governments introduced to commemorate their ascension to power have been rather short‐lived. Other holidays like Republic Day or Founder's Day have been longer

Recent plant photosynthate as a driver of ecological and evolutionary processes

open access: yesNew Phytologist, EarlyView.
Timeline of key eco‐evolutionary outcomes arising from belowground allocation of recent plant photosynthate from shoots. Summary Plants rapidly allocate carbon from photosynthesis belowground via root exudates and root‐associated microorganisms. Here we synthesise recent evidence of our understanding of the consequences of this ‘fast’ pathway of recent

Decomposition and mycorrhizal suppression of saprotrophs remain stable after wildfire and clearcut disturbance in boreal forests

open access: yesNew Phytologist, EarlyView.
Summary Boreal forests store a large portion of global terrestrial carbon, primarily in soils, yet their sensitivity to environmental changes remains uncertain. Disturbance is one major agent of change, with dominance shifting from wildfire to forest management over the past century.

Biomechanical Assessment of Root Torque in Clear Aligners: Impact of Trimline Design, Engagers, and Pressure Points With Palatal Compensation Movement

open access: yesOrthodontics &Craniofacial Research, EarlyView.
ABSTRACT Background Root torque control is essential for guiding the proper movement of anterior teeth, primarily to prevent periodontal complications. This movement, in clear aligner therapy (CAT), requires precise force application to minimize unintended displacements.

Warming Has Limited Effects on Carbon‐Use Efficiency of Wheat and Upland Rice Plants—Evidence From a 13CO2 Labelling Study

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plant carbon‐use efficiency (CUE) is a key parameter quantifying the net carbon gain with respect to gross carbon fixation. Although it is critical for carbon cycle models, it is often assigned an empirical value due to measurement difficulty. Uncertainty remains whether CUE is affected by warming. We quantified CUE in wheat (Triticum aestivum)
