Lineage‐specific phylogenetic structure of boreal habitats suggests different assembly processes across phylogenetic and spatial scales

open access: yesEcography, Volume 2025, Issue 12, December 2025.
The phylogenetic distance among species in a community (community phylogenetic structure) has been used to infer deterministic and stochastic assembly processes, albeit with criticisms. The effect of phylogenetic scale (old versus young lineages) and spatial scale on measures of CPS are rarely tested simultaneously, especially in the boreal biome, yet ...

Global importance of Amazonian freshwaters

open access: yesFrontiers in Ecology and the Environment, Volume 23, Issue 10, December 2025.
Amazonian freshwaters have large influences on regional and global climate, harbor remarkable and unique species, and are vital to human society. Nevertheless, as compared to their terrestrial counterparts in the Amazon, these freshwaters have received less attention from the international conservation community.

Societal willingness to pay for wild food conservation in Italy: Exploring spatial dimensions of preferences

open access: yesPeople and Nature, Volume 7, Issue 12, Page 3168-3181, December 2025.
Abstract Forests contribute to human well‐being by offering various ecosystem services (ES), including wild food and other products. While previous studies have typically focused on formally marketed wild foods, there is a growing need to understand the broader significance of wild foods as cultural ES and the factors influencing societal preferences ...

Wetland distribution modelling for optimal land use options in Europe [PDF]

open access: yes
This spatial study contributes to a modelling project that, in combination with biodiversity analyses and an economic model, evaluates potentials to preserve existing habitats, to restore formerly native habitats, as well as to create non-native managed ...

Microbial diversity in hummock and hollow soils of three wetlands on the Qinghai-Tibetan plateau revealed by 16S rRNA pyrosequencing

open access: yes, 2014
The wetlands of the Qinghai-Tibetan Plateau are believed to play an important role in global nutrient cycling, but the composition and diversity of microorganisms in this ecosystem are poorly characterized.

Rethinking Global Soil Degradation: Drivers, Impacts, and Solutions

open access: yesReviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The increasing threat of soil degradation presents significant challenges to soil health, especially within agroecosystems that are vital for food security, climate regulation, and economic stability. This growing concern arises from intricate interactions between land use practices and climatic conditions, which, if not addressed, could ...

The long-term fate of permafrost peatlands under rapid climate warming [PDF]

open access: yes, 2015
Permafrost peatlands contain globally important amounts of soil organic carbon, owing to cold conditions which suppress anaerobic decomposition. However, climate warming and permafrost thaw threaten the stability of this carbon store.
