The Role of Participatory Forest Management on Forest Composition, Diversity, and Regeneration: A Study of Guangua Elala Forest, Northwestern Ethiopia

open access: yesInternational Journal of Forestry Research, Volume 2026, Issue 1, 2026.
Participatory forest management (PFM) is increasingly recognized as an effective approach for forest conservation and sustainable resource use in Ethiopia, yet empirical evidence of its ecological outcomes remains limited. This study assessed the effects of PFM on forest composition, diversity, and regeneration in the Guangua Elala Forest, Northwestern

Ailanthus altissima Extract Ameliorates Cognitive Decline and Neurodegeneration in an Aluminum Chloride–Induced Rat Model of Alzheimer’s Disease

open access: yesJournal of Food Biochemistry, Volume 2026, Issue 1, 2026.
Background The extract of Ailanthus altissima possesses anti‐inflammatory and neuroprotective properties. We aimed to investigate its effectiveness in mitigating the AlCl3‐induced Alzheimer’s disease in a rat model. Methods A total of 32 adult male Wistar rats were divided into 4 groups each consisting of 8 rats.

A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Simaba docensis, a New Brazilian Species of Simaroubaceae

open access: yesNovon, 1999
Simaba docensis, a new species of Simaroubaceae, is described and illustrated. Its geographical distribution seems to be restricted to semideciduous forest in the region of the Rio Doce basin, Minas Gerais, southeastern Brazil. Accordingly, it is likely to be a rare endemic and endangered species.

Here, There and Everywhere: Widespread Non‐Native Plants in the World's Urban Ecosystems

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 11, November 2025.
ABSTRACT Aim To (a) produce a list of the most widespread naturalised non‐native plant species across cities of the world; (b) explore whether cities on different continents are invaded by the same group of widespread naturalised species; and (c) elucidate the origins of the most widespread naturalised urban species. Location Global.
