Beyond species means – the intraspecific contribution to global wood density variation

New Phytologist, Volume 249, Issue 6, Page 2630-2651, March 2026.
Summary Wood density is central for estimating vegetation carbon storage and a plant functional trait of great ecological and evolutionary importance. However, the global extent of wood density variation is unclear, especially at the intraspecific level. We assembled the most comprehensive wood density collection to date, including 109 626 records from

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 ...

Minimizing aviation lighting duration reduces bat attraction to wind turbines

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
This study provides empirical evidence that attraction behaviour of bats towards wind turbines is driven, at least partially, by red aviation lighting. We also demonstrate that smart lighting of wind turbines, such as the ADLS, could cost‐effectively help mitigate disruption of bat habitat use and the associated collision risks.

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

Journal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Socio‐Residential Inequalities and Inequalities at Elementary School: Repetition in French‐Speaking African Countries

African Development Review, Volume 37, Issue 4, December 2025.
Résumé Ce travail analyse, à partir de deux enquêtes PASEC (2014 et 2019), le redoublement à l’école primaire. Nous montrons que les enfants vivant en zone rurale ont, dans la majorité des pays, une probabilité plus élevée de redoubler avant le Grade 6.
