Disturbance and distributions: avoiding exclusion in a warming world

open access: yesEcology and Society, 2016
I highlight how disturbance determines species distributions and the implications for conservation practice. In particular, I describe opportunities to mitigate some of the threats to species resulting from climate change.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

The Policies of State Succession: Harmonizing Self-Determination and Global Order in the Twenty-First Century Tai-Heng Cheng, State Succession and Commercial Obligations [PDF]

open access: yes, 2006
I differ with Cheng\u27s appraisal of certain events and think that we need a more sophisticated analysis of the twin policy goals he identifies and embraces--self-determination and global order--before they can offer real policy guidance.
