Carbon Accumulation in Tropical Dry Forests and Savannas Despite Widespread Land‐Cover Change, Revealed by Radar Remote Sensing

open access: yesGlobal Change Biology, Volume 32, Issue 10, October 2026.
We map aboveground carbon density (AGCD) across tropical dry forests and savannas at 100 m for 2015–2024 using ALOS‑2 L‑band radar calibrated with field plots. Aboveground carbon (AGC) stocks total 25.3 ± 2 PgC (13% of global AGC) and net AGC is increasing at 0.43 ± 0.07 PgC yr−1 (20% of the land sink).

Climate Predicts Tree Dispersal Strategies Across Brazil's Ecosystems

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 7, July 2026.
ABSTRACT Aim We investigate the distribution of dispersal modes—endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and ...

Dinamica perturbărilor din rezervația naturală ”Făgetul Secular Humosu” aflată la limita estică a arealului European

open access: yesBucovina Forestieră, 2019
Sursa de bază pentru reconstituirea dinamicii perturbărilor dintr-un arboret o reprezintă inelele anuale. Importanța perturbărilor în dinamica unui ecosistem forestier se regăsește la nivelul modificărilor aduse structurii și funcționării acestuia ...

Functional Diversity and Community Composition of Soil Fungi Associated With Canopy Dieback in Araucaria araucana Forests of Contrasting Edaphic Conditions

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Soil fungal communities associated with Araucaria araucana differ primarily according to site edaphic conditions rather than tree health status. Restrictive, nutrient‐poor soils are linked to higher canopy dieback and distinct functional community shifts, with symptomatic trees harbouring stress‐tolerant taxa and asymptomatic trees supporting ...

Multiple global‐change drivers and cascading effects in Mediterranean ecosystems: Lessons from an iconic national park

open access: yesConservation Science and Practice, Volume 8, Issue 6, June 2026.
Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

Genetic Diversity, Population Structure and Evidence of Genetic Bottleneck in Geoffroea decorticans (Fabaceae): Implications for Conservation

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
We documented genetic variation, population structure, and bottleneck signals in Geoffroea decorticans (Fabaceae) populations across the Atacama Desert and emphasize the urgency of genetic monitoring. Conservation plans should prioritize populations based on genetic information including those with low diversity, strong bottleneck signals and high ...
