Intra-annual variations of plant and soil biota community in a grassland under nitrogen addition and mowing

Geoderma
Diversity and composition of plants and soil biota are critical determinants of fundamental ecosystem functions. Although the compositional responses of organisms across trophic levels to global change drivers and ecosystem management strategies have ...

Relationship between food quality and body size of common vole in different habitats

Pest Management Science, EarlyView.
The body size of the common vole in crop fields (alfalfa, rape, cereals) is larger than in less‐cultivated habitats (forests, clearings, set‐aside) and is not related to food quality. Abstract BACKGROUND There is a close relationship between habitat, food and demographic parameters of common vole populations.

Investigating boreal forest successional stages in Alaska and Northwest Canada using UAV‐LiDAR and RGB and a community detection network

Remote Sensing in Ecology and Conservation, EarlyView.
This study develops a novel application of UAV‐LiDAR and Red Green Blue (RGB) data and network analysis to enhance our understanding of boreal forest succession. The results indicate that tree height and spectral variables are the most influential predictors of plant functional type in random forest algorithms, and high overall accuracies were attained.

Comparing convolutional neural network and random forest for benthic habitat mapping in Apollo Marine Park

Remote Sensing in Ecology and Conservation, EarlyView.
A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

Tree Stands and Their Productivity Dynamics at the Upper Growing Limit in Khibiny on the Background of Modern Climate Changes [PDF]

, 2019
Within the ecotone of the upper limit of woody vegetation on the southeastern macroslope of the Khibiny Mountain ridge (Kola Peninsula), the spatial and age structure, as well as features of the phytomass accumulation of spruce–birch stands, were studied.

Innovation for Sustainable Development: Assessing Sustainability‐Oriented Innovations in the UK Palm Oil Supply Chains

Sustainable Development, EarlyView.
ABSTRACT This research evaluates the adoption of Sustainability‐Oriented Innovations (SOIs) by UK food manufacturers, particularly in the palm oil sector. Despite the global palm oil industry's environmental and social impacts, such as deforestation and labour exploitation, empirical studies on SOIs are limited. This paper addressed this gap by mapping
