Monitoring African Megafauna in an Anthropogenic Landscape: A 15‐Year Case Study of the Vulnerable West African Giraffe

open access: yesAnimal Conservation, Volume 29, Issue 3, Page 235-248, June 2026.
We used pattern recognition software to correct misidentifications in a 15‐year photographic database of the last, vulnerable West African giraffe population in Niger. After revealing substantial methodological errors that had inflated population estimates by nearly 19%, we corrected individual encounter histories and applied capture‐mark‐recapture ...

Relative detectability of Canadian plant species at risk in field surveys

open access: yesConservation Science and Practice, Volume 8, Issue 6, June 2026.
Accurate detection is essential for estimating plant populations and ranges, yet many at‐risk plant species in Canada remain under‐studied in this regard. To address this, we ranked 199 at‐risk vascular plants by relative detectability based on traits like life cycle, habitat, and flower color, finding that perennial species, those with conspicuous ...

La nature en forêt : qualités clés à conserver

open access: yesRevue Forestière Française, 2015
La biodiversité et les processus fonctionnels de l’écosystème dépendent en forêt de qualités écologiques élémentaires que l’on retrouve spontanément dans les forêts naturelles, à savoir : diversité des espèces, des peuplements et des habitats associés ...

Shaping future forests: how can ecophysiology support climate‐smart forest management?

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Stability in tapia woodlands amid non‐native expansion: Integrating traditional ecological knowledge and remote sensing to track 73 years of tree cover in Madagascar

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1403-1418, May 2026.
Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

Hunting and fishing harvest data collection: a horizon scanning exercise from the French context

open access: yesWildlife Biology, Volume 2026, Issue 3, May 2026.
Legal and societal moves increasingly lead leisure hunting and fishing practitioners to record their harvest. The total number of individuals harvested per population per year is the minimum required information to feed into demographic models and allow science‐based management. Some few schemes record more detailed data, hence allowing better‐informed

Dynamics of neutral genes and genes under selection and their implications for threatened species translocations

open access: yesJournal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our results provide advice for the management of wild populations and the planning of translocations. Prior to this study, the understanding was deduced from genetic theory, which did not consider stochastic events included in our simulations. Our modelling showed an overall increase in genetic diversity resulting from translocations, suggesting that ...

Construction d’un modèle d’estimation du nombre de lamproies sur frayère en utilisant un simple comptage de nids

open access: yesSciences, Eaux & Territoires
L’estimation des effectifs d’une population nécessite de prendre en compte la biologie de l’espèce mais aussi des contraintes logistiques comme le coût humain et matériel.
