China's Eco‐Civilisation, Climate Leviathan, and Hobbesian Energy Transition
Antipode, Volume 57, Issue 3, Page 830-861, May 2025.Abstract Scholars have hitherto tended to theorise China's ecological civilisation project either as a form of environmental authoritarianism or as a vision of eco‐socialism. This paper contributes to the conversation by conducting a textual analysis of Chinese scholarly discussions on eco‐civilisation.

Wildlife Letters, Volume 2, Issue 4, Page 192-203, December 2024.Knowledge of the reproductive success of organisms in urban habitat fragments is needed to conserve biodiversity in our urbanizing world. We found that differences in nest success among birds in urban forest patches is explained by factors on three distinct spatial scales even across a limited urban development gradient.

Linking extinction risk to the economic and nutritional value of sharks in small‐scale fisheries
Conservation Biology, Volume 38, Issue 6, December 2024.Abstract To achieve sustainable shark fisheries, it is key to understand not only the biological drivers and environmental consequences of overfishing, but also the social and economic drivers of fisher behavior. The extinction risk of sharks is highest in coastal tropical waters, where small‐scale fisheries are most prevalent.
