From waste to resource: Garlic peel‐derived proteases (Allium sativum) for nematode control

Environmental Progress &Sustainable Energy, Volume 44, Issue 4, July/August 2025.
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

Scaling Up Bark Hydrology: Tree Size and Functional Traits Shape Water Storage in a Tropical Cloud Forest

Hydrological Processes, Volume 39, Issue 7, July 2025.
This study reveals that tree structure, especially bark volume, is the primary driver of bark water uptake in tropical montane cloud forests. Despite minor differences in intrinsic bark traits across species, whole‐tree water storage varies significantly.

Transcriptional response in larvae of the generalist fruit fly Anastrepha obliqua feeding on three different tropical host plants

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 708-723, July 2025.
We investigated the molecular basis of host switching by the phytophagous West Indian fruit fly (A. obliqua). Third‐instar larvae showed differential gene expression according to host plants: red mombin, mango, and carambola. The main gene categories differentially expressed were digestion, detoxification, and gene regulators.

Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests

Global Change Biology, Volume 31, Issue 7, July 2025.
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...

First Results About Pollination of Silene migjornensis, an Endemic Plant Species of the Southern Dunes of Mallorca

Journal of Applied Entomology, Volume 149, Issue 6, Page 882-887, July 2025.
ABSTRACT Silene migjornensis is a plant species restricted to a unique location in the south of Mallorca. Its floral syndrome suggests nocturnal pollination by lepidopterans, but pollinators of this species remain unknown. Several surveys were conducted along the flowering period, and potential pollinators were captured for pollen load analyses ...
