A Reserve of Light: Photography, Ethnography, and Lucid Memory in Contemporary Chile

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT This article takes shape as a shared inquiry between an ethnographer and a photographer, in continuity with the photographic archive of Luis Poirot. Through sustained encounters with his images and archival practices, the text does not position itself outside the archive that motivates it, but unfolds from within it.

Designing networks of freshwater and marine conservation areas accounting for cross‐realm connectivity and threat propagation

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
This study highlights the importance of integrating cross‐realm connectivity and threat propagation when designing new or expanding existing networks of conservation areas, such as the Natura 2000 European network of protected areas. These findings emphasize the need for multirealm planning that supports species persistence, protects transitional ...

Phytochemical diversity of naturally regenerated plants in a biodiversity enrichment experiment

Journal of Ecology, Volume 114, Issue 3, March 2026.
Tree islands established within an industrial oil palm plantation promoted the recovery of phytochemical diversity through natural regeneration. Ten years after planting, untargeted metabolomics of 76 regenerating woody species detected 27,122 phytochemical features, including many novel compounds. Larger islands supported higher woody species richness
