The NDICEA model: a supporting tool for nitrogen management in arable farming [PDF]

open access: yes, 2009
Nitrogen use efficiency is an important item in organic farming. Modelling nitrogen dynamics can help to understand the impact of alternative agronomic practices and thus assist in decision making.

Breaking Down Lignin: A Macromolecule's Path to the Nanoscale

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
This section highlights lignin's critical role as a sustainable, multifunctional precursor for nanomaterial design. Its unique structure and abundance enable the creation of lignin‐based, lignin‐derived, and hybrid nanomaterials with tunable properties. Emphasis is placed on lignin's potential to drive innovation in nanotechnology, offering ecofriendly

Effects of Ponderosa Pine Ecological Restoration on Forest Soils and Understory Vegetation in Northern Arizona [PDF]

open access: yes, 2017
The human exclusion of wildfire and overgrazing by livestock since settlement have caused dramatic changes in ponderosa pine (Pinus ponderosa Dougl ex Laws) forest ecosystems.

Development, Nutritional Evaluation, and Shelf‐Life Study of a Jackfruit‐Based Meat Analogue Enriched With Legumes and Spirulina

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
A jackfruit‐based meat analog enriched with legumes and spirulina was developed, optimized, and evaluated for sensory, nutritional, and shelf‐life qualities. The best formulation offered superior taste, texture, nutrient density, and maintained safety and quality for up to 60 days under frozen storage. ABSTRACT This study focuses on the development and

A Female‐Locust‐Inspired Hybrid Soft‐Stiff Robotic Digger: Mimetics and Implications for Digging Efficiency

open access: yesAdvanced Intelligent Systems, EarlyView.
Female desert locusts dig underground to lay their eggs. They displace soil, rather than removing it, to create a tunnel. We analyze burrowing dynamics and 3D kinematics and design a locust‐inspired hybrid soft–stiff robot that reproduces this mechanism. The results show the natural strategy minimizes energy, whereas alternative patterns raise costs up

Color polymorphism in Anemone coronaria: Correlations with soil, climate, and flowering phenology

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Flower color polymorphism (FCP) is thought to be driven by multiple selection agents. Although widely associated with visual attraction of multiple pollinators, FCP is also often correlated with abiotic factors. We explored the links between abiotic conditions, flowering phenology, and FCP in the winter‐flowering geophyte Anemone ...

The contribution of mineralization to grassland N uptake on peatland soils with anthropogenic A horizons [PDF]

open access: yes
Peatland soils contain large amounts of nitrogen (N) in the soil and mineralization can contribute substantially to the annual mineral N supply of grasslands. We investigated the contribution of N mineralization from peat with respect to the total annual

Temperature and the evolution of flower color: A review

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.

Electromembrane Extraction for Multiclass Pesticide Assessment in Soil Matrices: Sustainable Analytical Insights

open access: yesAnalysis &Sensing, EarlyView.
The U‐shaped electromembrane extraction with liquid chromatography‐mass spectrometry enables rapid multiclass pesticide screening in soil. The 15 min, low‐solvent workflow achieves high recoveries and robust linearity, while AGREEprep and GAPI assessments highlight a greener profile compared to literature reports, which represents a smart strategy for ...
