Similar Relative Carbon Costs for Construction and Storage of Sun and Shade Branches in Mature Temperate Trees

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Irradiance strongly affects the morphology, carbon (C) uptake and construction costs of leaves and branches. Within tree crowns, light decreases from the top downwards, but whether this translates to differences in the C balance of sun and shade branches remains unclear. Here, we combined a light‐driven photosynthesis model, parameterised with

Subterranean glacial spillways: an example from the karst of South Wales, UK [PDF]

open access: yes, 2013
Many karst areas in the UK have been glaciated one or more times during the last 0.5 Ma, yet there are few documented examples of caves in these regions being affected by glacial processes other than erosion.

Drought legacy in mature spruce alleviates physiological stress during recurrent drought

open access: yesPlant Biology, EarlyView.
The slow recovery of leaf area in mature spruce following a long‐term drought alleviated physiological stress during recurrent drought. Abstract Forest ecosystems are facing severe and prolonged droughts with delayed recovery, known as “drought legacy”.

Research advance for uranium isotope as a quantitative proxy for paleo-oceans anoxic or oxic environment

open access: yesCarsologica Sinica
Compared with other elements that are sensitive to redox environments (U, Mo, V, S, Fe, Cu, Zn, Ni), uranium isotopes have the advantage to quantitatively reflect long-term and global-scale paleoredox of oceans, due to its uniform composition in the ...

Root water uptake depth in temperate forest trees: species‐specific patterns shaped by neighbourhood and environment

open access: yesPlant Biology, EarlyView.
Root water uptake strategies vary among temperate tree species (European beech, Douglas fir, and Norway spruce), with beech–conifer mixtures altering water uptake depths, while site conditions and temporal dynamics further shape the contribution of different soil depths to water supply.

Biodiversity and its restoration in limestone quarries: a review

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Limestone quarries impact natural areas, and they are spreading in relation to human population growth. Little is known about the impact of limestone quarries and their restoration on biodiversity. Objectives This review aims to provide an overview of how biodiversity is assessed in limestone quarries, how it impacts biodiversity,

Tracer Test as a Tool for Optimizing the Flow Patterns and Efficiency of a Full‐Scale Drainage Water Treatment Wetland

open access: yesWater and Environment Journal, EarlyView.
Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.
