Survival, rarity, and extinction in tropical stony corals
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Many reef‐building tropical corals are becoming rare. We considered the meaning of rarity in corals and highlighted taxa that have reached low abundances in the last few decades. The difficulties of quantifying rarity in the marine environment arise from the sheer scale and 3‐dimensional nature of the biome and the inherent challenges therein ...

Comparison of drone and ground surveys for the detection of a rare plant in a fragile ecosystem
Ecological Solutions and Evidence, Volume 7, Issue 1, January/March 2026.We compared the accuracy, time, and financial costs of drone and ground surveys for the detection of wood lilies (Lilium philadelphicum) in an endangered alvar ecosystem. We found that the drone surveys detected 73%–78% of the plants found in the ground surveys, but that this type of survey was more expensive and time consuming than the ground survey ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.ABSTRACT Climate change significantly threatens biodiversity, particularly in freshwater ecosystems, which host many endemic and threatened species. Among them, aeglids stand out as strictly endemic, ecologically important and highly threatened crustaceans, making them a relevant model for investigating the impacts of climate change on aquatic ...

Ecosphere, Volume 17, Issue 1, January 2026.Abstract Environmental and human factors shape the distribution and habitat of Mediterranean woody plants, influencing their population structure and conservation. The Iberian wild pear (Pyrus bourgaeana), a keystone fleshy‐fruited species supporting wildlife during resource‐scarce periods, is one such example.
