Ecography, EarlyView.Populations at the edge of a species' distribution often encounter more challenging environmental conditions than those at the core, requiring unique adaptations and strategies. However, the demographic processes driving these populations remain poorly understood.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization
Ecography, EarlyView.Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study explores the structure–activity relationship of Schottky heterojunctions coupled with multi‐level core‐shell structures. Copper‐based yolk‐double shell heterojunction microspheres (Cu/Cu2O@C‐2shell) are constructed using a heterogeneous contraction and reduction strategy to promote the targeted separation of electron–hole pairs, accumulate ...

Terpenes and Terpenoids: How can we use them?
European Journal of Organic Chemistry, EarlyView.The transition from petroleum‐based to renewable bio‐based chemicals has led to increased interest in terpenes and terpenoids. This overview highlights their chemistry, focusing on their reactivity and applications in polymerizations, total syntheses, pharmaceuticals, and bio‐based chemical conversions; promoting sustainable and green chemical ...

From waste to resource: Garlic peel‐derived proteases (Allium sativum) for nematode control
Environmental Progress &Sustainable Energy, EarlyView.Abstract This study aimed to prepare a protease‐rich extract from garlic peel (Allium sativum) and evaluate its nematicidal potential. The garlic peel was crushed, suspended in distilled water, and the obtained extract was subjected to filtration, centrifugation, and dialysis to concentrate the proteases. The nematicidal activity was tested in vitro on

Exploring biomarkers of neurodegeneration in epilepsy: Critical insights
Epileptic Disorders, EarlyView.Abstract The advent of biofluid biomarkers for neurodegenerative disorders has precipitated a surge in recent evidence regarding their role in epilepsy. In this literature review, we examine the diagnostic, prognostic, and therapeutic potential of several biomarkers, including amyloid‐beta (Aβ) protein, total (t‐tau), phosphorylated tau (p‐tau) protein,

Germinal centers develop in the B cell follicles of secondary lymphoid tissues during T cell-dependent (TD) antibody responses. The B cells that give rise to germinal centers initially have to be activated outside follicles, in the T cell-rich zones in association with interdigitating cells and T cell help.

Despite being relatively insensitive to environmental insult, the spore is responsive to low concentrations of chemical germinants, which induce germination. The process of bacterial spore germination involves membrane permeability changes, ion fluxes and the activation of enzymes that degrade the outer layers of the spore.
