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

open access: yesLand 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.

Vegetation Structure and Diversity Under Farmer Managed Natural Regeneration: A Comparison of Silvo‐Arable and Silvo‐Pastoral Systems in Kenya

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Farmer Managed Natural Regeneration (FMNR) is a low‐cost, adaptable agroforestry practice that enhances land restoration by promoting systematic integration of naturally regenerating trees within farming systems through tree selection and management.

Underground Lag: Fungal Community and Edaphic Legacies After Disturbance

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Páramos are neotropical mountain ecosystems that regulate water and store large amounts of carbon, but are increasingly degraded by agriculture and grazing. Although native vegetation often recolonizes after abandonment, belowground recovery remains poorly understood.

Optical Skyrmions with Tunable or Reconfigurable Topology Using Spin‐Decoupled Metaoptics

open access: yesLaser &Photonics Reviews, EarlyView.
The work introduces advanced optical elements capable of generating and dynamically reconfiguring complex light patterns known as optical skyrmions. By precisely shaping light polarization at the nanoscale, a single engineered metasurface can generate and manipulate robust and tunable polarization textures in an efficient and scalable way.

Revealing the Resonant Physics of Open Photonic Time Crystals

open access: yesLaser &Photonics Reviews, EarlyView.
ABSTRACT Photonic time crystals (PTCs) are media whose permittivity is modulated periodically in time, enabling momentum bandgaps and parametric amplification of light. Their realization at the nanoscale can revolutionize the study of light‐matter interactions.

Reinstatement and generic reassignment of Phyllanthus asteranthos Croizat (Phyllanthaceae) based on living plant observations and specimen analysis

open access: yesNordic Journal of Botany, EarlyView.
Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...
