Enhanced fish detection sensitivity in aquatic systems using environmental RNA

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Environmental RNA (eRNA) can potentially augment the biological monitoring ability of the established environmental DNA (eDNA) application in conservation. Despite faster degradation, environmental RNA could offer unique advantages: it may help reduce the legacy signal compared to eDNA, provide insights into physiological status through gene ...

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Simplification of woody plant trait networks among communities along a climatic aridity gradient

open access: yesJournal of Ecology, Volume 113, Issue 4, Page 896-912, April 2025.
Hypothesized associations of plant trait network parameters with climatic aridity and ecosystem structure and with trait coefficients of variation across six plant communities of the California Floristic Province. (a) Across this gradient, the climatic aridity increased from the mixed conifer‐broadleaf forest site to the desert site.

The Unstable Relationship Between Drought Status and Leaf Water Content Complicates the Remote Sensing of Tree Drought Stress

open access: yesGlobal Change Biology, Volume 31, Issue 4, April 2025.
Remote sensing can monitor plant drought stress across ecosystems but is limited by uncertain links between physiological stress and measurements of water content. We examined how water potential and water content, measured in the field, laboratory, and via airborne imaging, vary over time and space in two oak species.
