Underground Lag: Fungal Community and Edaphic Legacies After Disturbance

Land 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.

Soil and Forest Degradation Driven by Cattle Grazing and Selective Logging in Sub‐Antarctic Nothofagus Ecosystems of Patagonia

Land Degradation &Development, EarlyView.
ABSTRACT Soil and forest degradation driven by chronic land‐use pressures is an increasingly widespread process in forested landscapes worldwide, yet its empirical characterization remains limited, particularly in temperate and sub‐Antarctic ecosystems.

Beyond the Lamppost: Optimal Prevention and Control of the Brown Treesnake in Hawaii [PDF]

In this paper, an integrated model for the prevention and control of an invasive species is developed. The generality of the model allows it to be used for both existing and potential threats to the system of interest.

Mechanical Properties and Testing Strategies for Two‐Photon Lithography: A Review of Current Practices and Emerging Challenges

Laser &Photonics Reviews, EarlyView.
Two‐photon lithography enables the fabrication of complex 3D microstructures with tunable mechanical properties spanning from soft hydrogels to rigid hybrid networks. This review summarizes how material composition, printing parameters, and post‐processing govern stiffness and viscoelasticity, highlighting advanced characterization methods and emerging

An exotic species is the favorite prey of a native enemy.

, 2011
Although native enemies in an exotic species' new range are considered to affect its ability to invade, few studies have evaluated predation pressures from native enemies on exotic species in their new range.

Osteoarthritis: An Immuno‐Inflammatory Disease‐Mechanisms of Immune Cell Dysregulation and Potential Therapeutic Strategies

Med Research, EarlyView.
This review summarizes the immuno‐inflammatory mechanisms driving the pathogenesis of osteoarthritis (OA), extending beyond the traditional view of OA as a purely degenerative disease to incorporate immune cell infiltration, inflammatory factor release, and the formation of a chronic low‐grade inflammatory microenvironment.

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

Nordic 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 ...

Sexual reproduction in invasive Japanese knotweed (Reynoutria japonica) in south Sweden

Nordic Journal of Botany, EarlyView.
To understand the potential for northward expansion of knotweeds into currently uninvaded regions, it is crucial to assess the potential for sexual reproduction alongside the ongoing vegetative spread. For that reason, we tested viability in Reynoutria japonica seeds in south Sweden, a region where viable seeds had not been previously reported ...

Competition model for two exotic species and one native species

, 2002
The spread of two exotic plant species and the corresponding replacement of a single native species is examined as a competition model with spatial considerations.
