Carbon, Nitrogen, and Corresponding Stable Isotope Signatures Reveal Channel Banks as Major Sediment Sources in a Tropical Agricultural Watershed

Land Degradation &Development, EarlyView.
ABSTRACT Uncertainties about the applicability of δ13C and δ15N as tracers of sediment sources in tropical river basins highlight the need for more in‐depth investigations of these isotopes. This study therefore assessed the effectiveness of δ13C and δ15N signatures in discriminating sediment sources in an agricultural catchment in Northeast Brazil ...

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Age-Dependent Developmental Response to Temperature: An Examination of the Rarely Tested Phenomenon in Two Species (Gypsy Moth (Lymantria dispar) and Winter Moth (Operophtera brumata))

Insects, 2018
The pervading paradigm in insect phenology models is that the response to a given temperature does not vary within a life stage. The developmental rate functions that have been developed for general use, or for specific insects, have for the most part ...

Synergistic Effects of Salinization and Artificial Root Exudates on Soil Phosphatase Activity in Coastal Soil

Land Degradation &Development, EarlyView.
ABSTRACT Coastal soil salinization from rising seawater levels has adverse impacts on soil function, seed germination, and plant growth. Root exudates play a key role in supporting microbial activity, nutrient cycling, and plant health, yet little is known about the combined effects of salinization and the addition of artificial root exudates (AREs) on

A Multiple Soil Threats Assessment for Europe by 2050

Land Degradation &Development, EarlyView.
ABSTRACT European soils are exposed to multiple interacting soil threats (STs), challenging the European Commission's objective of restoring healthy soils by 2050. This study provides the first integrated EU‐scale projection of four major soil threats—soil compaction, soil organic carbon loss, soil erosion and soil sealing—under two IPCC climate ...

Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, EarlyView.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

Multi‐Scale Pathways to Integrated Protection and Restoration of Mountains, Rivers, Forests, Farmlands, Lakes, and Grasslands in the Three Gorges Reservoir Area: A Social‐Ecological Systems Perspective

Land Degradation &Development, EarlyView.
ABSTRACT Human activities have intensified eco‐environmental problems, challenging harmonious human‐nature interactions. However, existing integrated protection and restoration (IPR) zoning approaches for mountains, rivers, forests, farmlands, lakes, and grasslands (MRFFLG) focus on a single scale and fail to incorporate the ecological network (EN) and

Phylogeography, Historical Population Demography, and Climatic Modeling of Two Bird Species Uncover Past Connections Between Amazonia and the Atlantic Forest

Ecology and Evolution
We combined mitochondrial DNA sequence data and paleoclimatic distribution models to document phylogeographic patterns and investigate the historical demography of two manakins, Ceratopipra rubrocapilla and Pseudopipra pipra, as well as to explore ...

Taxonomic reappraisal of the mangrove genus Avicennia (Acanthaceae) in India

Nordic Journal of Botany, EarlyView.
A taxonomic reappraisal of the mangrove genus Avicennia in India was undertaken through extensive field surveys and critical examination of herbarium specimens. Three taxa, Avicennia alba, Avicennia marina subsp. marina, and Avicennia officinalis, are described in detail. A synonymic list was compiled using the World Checklist of Vascular Plants (WCVP)
