Determining fPAR and leaf area index of several land cover classes in the Pot River and Tsitsa River catchments of the Eastern Cape, South Africa [PDF]

open access: yes, 2017
Determining the quantum (both annual maxima and minima) and the temporal variation in the leaf area index (LAI), and the fraction of photosynthetically active radiation (fPAR), are three fundamental biophysical characteristics of the plant canopy that ...

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

open access: yesEcography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Fishing for Anglers in a Sea of Data: Using Mobility Data to Identify and Track Marine Recreational Fishing

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Analysing recreational anglers in marine waters presents several challenges. First, while there are well‐established approaches to estimate fishing effort, they are only as good as the coverage of the underlying data, which invariably has blind spots that can bias estimates. Additionally, tracking anglers' movements over time and their fishing

Forest canopy analysis in the Alpine environment: comparison among assessment methods

open access: yesForest@, 2013
Forest canopy analysis in the Alpine environment: comparison among assessment methods. Forest canopy is an important ecological feature of forest stands and can be expressed as Leaf Area Index (LAI) or canopy cover percentage.

A Comparative Investigation of Undergraduate Dental Student Stress in the Management of Deep and Moderate Carious Lesions

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim The primary objective of this clinical study was to analyse, through physiological and psychological parameters, undergraduate dental student stress during the management of deep compared with moderate carious lesions. Additional objectives aimed to compare student confidence, anxiety and satisfaction during deep and moderate caries ...

Light regulates tomato fruit metabolome via SlDML2‐mediated global DNA demethylation

open access: yesJournal of Integrative Plant Biology, EarlyView.
In tomato growth and development, red and blue light signals are captured by the photoreceptors phyB2 and CRY1a, which kickstart tomato fruit ripening by activating HY5, which activates DNA demethylation via DML2 to trigger a metabolic and ripening transformation cascade within the tomato.
