Automated quantification of fine root production from minirhizotron image time series

Methods in Ecology and Evolution, Volume 17, Issue 3, Page 758-767, March 2026.
Abstract Plant root growth accounts for a major part of the net primary production in grassland and forest ecosystems and influences the global carbon and nutrient cycles. Measuring the production of roots is inherently difficult, prone to inconsistencies and time‐consuming. Notably, there are currently no methods yet to automate this task.

Spatial and Temporal Variations in Active Layer Thawing and Their Implication on Runoff Generation in Peat-Covered Permafrost Terrain [PDF]

, 2009
The distribution of frost table depths on a peat-covered permafrost slope was examined in a discontinuous permafrost region in northern Canada over 4 consecutive years at a variety of spatial scales, to elucidate the role of active layer development on ...

Determinants of Terrestrial and Limnic Species Richness in Germany

Diversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Biodiversity is increasingly threatened by human impacts. While abiotic conditions are well known to shape species richness, the role of human activities remains less clear. We examined how abiotic and human factors influence terrestrial and limnic species richness in a densely populated region with a long land‐use history.

Orchids in the Open: Understanding Biodiversity Beyond Madagascar's Forests

Diversity and Distributions, Volume 32, Issue 3, March 2026.
ABSTRACT Aim Orchids make up 8% of Madagascar's vascular plant species richness and are typically associated with the island's forests. Yet most of the island is covered by open ecosystems, long dismissed as degraded. This perception has contributed to their neglect, limiting our understanding of species ecology and hindering conservation action in ...

Variety in evolutionary strategies favours biodiversity in habitats of moderate productivity [PDF]

, 2011
The mechanism whereby biodiversity varies between habitats differing in productivity is a missing link between ecological and evolutionary theory with vital implications for biodiversity conservation, management and the assessment of ecosystem services ...

Influence of topography and moisture and nutrient availability on green alder function on the low arctic tundra, NT [PDF]

, 2017
The Arctic has warmed by at least 3°C over the past 50 years and this rapid warming is expected to continue. Climate warming is driving the proliferation of shrubs across the tundra biome with implications for energy balance, climate, hydrology, nutrient

Climatically Driven Stability in the Alpine/Moorland Boundary on Three Mountains in Southwest Lutruwita/Tasmania 1986–2020

Journal of Vegetation Science, Volume 37, Issue 2, March/April 2026.
This study examined the alpine/moorland ecotone in southwest Lutruwita/Tasmania for impacts of climate change over 34 years. The results showed a stable vegetation boundary. It is likely the observed increase in wind and constant windward sea surface temperature are ameliorating impacts from rising atmospheric temperatures.

Patterns and determinants of plant- and microbial-derived carbon in alpine peatlands

Journal Of Plant Ecology
Abstract Peatlands store approximately one-third of global soil organic carbon (SOC) and clarifying SOC sources is essential to assess soil C formation and stability in these C-rich ecosystems. However, large-scale patterns and drivers of plant- and microbial-derived C remain poorly understood in peatlands.
