Opposing Association of Lung Neutrophils and PD-L1<sup>+</sup> Monocytes in Age-Related Severity of SARS-CoV-2 Infection. [PDF]

open access: yesAging Cell
Aging skews pulmonary myeloid responses during acute SARS‐CoV‐2 infection toward severe disease. Disease progression is characterized by excessive lung neutrophil accumulation together with impaired activation of classical monocytes, including a defect in PD‐L1 upregulation.

Does habitat modification impact morphology, performance, and inflammatory responses in an amphibian with limited dispersal capacity (<i>Lisssotriton helveticus</i>)? [PDF]

open access: yesEcol Evol
We studied the impact of habitat modifications on Palmate newt populations in the Ile de France region across four types of habitats: urban, mixed, agricultural, and natural. For each habitat, we measured the morphology of newts, quantified maximal running and swimming speed and acceleration, and quantified the immune response. Abstract The environment

Nutrient‐based species selection is a prevalent driver of community assembly and functional trait space in tropical forests

open access: yesJournal of Ecology, Volume 111, Issue 6, Page 1218-1230, June 2023., 2023
Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.

The importance of communal forests in carbon storage: Using and destabilizing carbon measurement in understanding Guatemala's payments for ecosystem services

open access: yesCanadian Geographer / Le géographe canadien, Volume 67, Issue 1, Page 106-123, Spring / printemps 2023., 2023
Payments for ecosystem services (PES) are a conservation initiative that offer payments to people who own or manage lands that provide desired ecosystem services. Utilizing mixed methods, I examine how PES in the form of government‐issued forestry incentives interact with land tenure to affect carbon storage in Guatemala's Western Highlands.

Growth, mortality and regeneration responses to ecological forestry treatments are shaped by local factors, species, and initial treatment impact

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
In mixed stands, coniferous species showed growth benefits when coexisting with broadleaf species, possibly due to reduced intraspecific competition or improved access to resources mediated by broadleaf neighbours. This growth advantage was not observed for broadleaf species, indicating asymmetric benefits in mixed stands.

La forêt : puits de carbone. [PDF]

open access: yes, 2000
Très majoritairement jeune et en pleine expansion, la forêt méditerranéenne constitue un important puits potentiel de carbone, autant dans la biomasse aérienne que dans les sols actuellement dégradés et pauvres en matière organique.

Gestion participative des forêts au Burkina Faso: analyse de la mise en œuvre selon les perceptions locales

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 3, Autumn / automne 2026.
Résumé La gestion participative constitue un pilier fondamental de la politique forestière nationale du Burkina Faso. Pourtant, dans la forêt de Bontioli, sa mise en œuvre révèle un décalage persistant entre les ambitions institutionnelles et les pratiques effectives, dans un contexte marqué par de fortes pressions sur les ressources, des capacités ...

Ecological factors shaping post‐fire resilience in mature black spruce forests of eastern North America

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Our study provides an assessment of the fire resilience of mature black spruce (BS) forests. A third of pre‐fire mature closed‐canopy stands are expected to transition into open woodlands. While mature BS‐dominated forests are considered more fire‐resilient than younger stands, our study raises concerns about their capacity to persist under the ...
