Beaver Damming Alters Sedge Phenology Through Water Table and Temperature Feedbacks in a Rocky Mountain Peatland

open access: yesEcohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT Beaver dams substantially reshape peatland hydrology, yet their influence on plant phenology, a key driver of ecosystem carbon dynamics, remains poorly understood. We used UAV‐based RGB imagery to quantify seasonal changes in greenness (GCC) of sedge (Carex spp.) across three hydrological treatments in a Canadian Rocky Mountain peatland ...

Factors affecting intraspecific diet variation of ducklings: Niche partitioning in a heterogeneous landscape?

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Variability in resource use within populations of free‐ranging animals can influence demographic and evolutionary processes. Yet in many ecological systems, the extent of intra‐population variation in the resources that animals consume and the environmental factors that contribute to this variance remain poorly understood. For example, dietary

Integrating land sharing and sparing paradigms in grassland ecology: A perspective on balancing livestock production and biodiversity

open access: yesGrassland Research, Volume 4, Issue 4, Page 389-395, December 2025.
This study explores how dispersed grazing (grassland sharing) enhances biodiversity and ecosystem health compared to concentrated grazing (grassland sparing) in Inner Mongolia's grasslands, balancing livestock production with conservation. Abstract The increasing global demand for livestock products (meat, milk, and wool) drives overgrazing, leading to

Hyperspectral imaging has a limited ability to remotely sense the onset of beech bark disease

open access: yesRemote Sensing in Ecology and Conservation, Volume 11, Issue 6, Page 656-669, December 2025.
Although hyperspectral imaging is a powerful remote sensing tool, it proved ineffective in predicting the progression of beech bark disease, except in its later stages, both at the canopy and leaf levels. While some alterations in chlorophyll, water content, and canopy structure may have influenced foliar reflectance at the canopy scale, as suggested ...

Nomenclature and typification of sectional names in Carex (Cyperaceae)

open access: yesTAXON, Volume 74, Issue 6, Page 1543-1568, December 2025.
Abstract This paper presents an updated survey of all the published names at the section rank in Carex and its formerly accepted satellite genera. We included related names at other ranks when relevant. We address validity, legitimacy, priority, typification, and – if relevant – synonymy.

Methane Transport Pathways and Oxidation in a Minnesota Bog

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Despite the widely recognized importance of wetland CH4 emissions as a climate change feedback, simultaneous measurements of CH4 transport pathways and oxidation in a wetland are rare. Thus, these critical components of many CH4 models are poorly parameterized because of the lack of appropriate data.
