Understanding the long‐term dynamics of vegetation since 1953 in high‐mountain regions

open access: yesJournal of Ecology, Volume 113, Issue 2, Page 485-503, February 2025.
Alpine ecosystems show complex shifts in species ranges and community structures due to climate, land use, geomorphology, and species interactions. Over 70 years, vegetation patterns in an alpine to nival environment were shaped by trends including drying wetlands, upward species migration, eutrophication, and snowbed vulnerability, highlighting the ...

Beyond 4 × 4: Paramotoring a novel approach to accelerate plant exploration in challenging environments

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 1, Page 87-104, January 2025.
Addressing the burning environmental crisis, we explore how the ‘extreme sport’ of paramotoring can enhance and accelerate scientific exploration with minimal environmental impact compared to off‐road vehicles. Our study demonstrates the scientific potential of paramotoring to access fragile desert ecosystems and investigate unrecorded habitats and ...

Net primary productivity and litter decomposition rates in two distinct Amazonian peatlands

open access: yesGlobal Change Biology, Volume 30, Issue 8, August 2024.
Our understanding of carbon cycling in tropical peatlands is limited by the lack of data on forest productivity and litter decomposition. Here we present measurements from two floristically distinct Amazonian peatland forests, a palm‐dominated swamp and a thin‐stemmed hardwood swamp.

Importance of methodological pluralism in deriving counterfactuals for evidence‐based conservation

open access: yesConservation Biology, Volume 38, Issue 3, June 2024.
Abstract Most protected area impact research that uses counterfactuals draws heavily on quantitative methods, data, and knowledge types, making it valuable in producing generalizations but limited in temporal scope, historical detail, and habitat diversity and coverage of ecosystem services.
