Henbit is an attainable cover crop

open access: yesAgricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Henbit is a short‐season plant that grows through the winter. It seeds itself in the spring with seeds that stay dormant through the summer and germinate in the fall. Winter growth makes henbit a good cover crop for the offseason of summer cash crops. Abstract Henbit (Lamium amplexicaule L.) is a potential cover crop in the Central United States, but ...

The impacts of biological invasions

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Chemical Markers and Bioactivity of Algerian Royal Jelly: Influence of Bee Subspecies, Geography, and Lyophilization

open access: yesChemistry &Biodiversity, Volume 23, Issue 6, June 2026.
Algerian royal jelly from native honey bees shows chemical diversity influenced by geography and subspecies. Lyophilization preserves key compounds, including 10‐HDA and phenolics. Biological assays reveal modest antioxidant activity and selective cytotoxicity against Reh leukemia cells, while anti‐inflammatory effects are limited.

Multi‐Omics Analyses Elucidate the Venom Components of the Wasp Vespa mandarinia

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
The wasp Vespa mandarinia was widely reared in Yunnan province. The venom was responsible for their aggressive behavior. Tweety proteases, hyaluronidase, venom dipeptidyl peptidase 4, and phospholipase A1 and A2 isozyme were identified. In addition, organic heterocyclic compounds, organic acids, and derivatives were found.

Evolutionary Patterns of the Genes Involved in the Integrity and Segregation of Chromosomes in Sawflies (Hymenoptera: Symphyta)

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
This study identifies and characterizes the genes encoding cohesin and condensin complexes across Symphytan superfamilies, revealing their structural and functional roles with conserved motifs in maintaining genome stability. Phylogenetic analyses indicate that SMC genes originated from ancient duplication events, with notable gene loss (e.g., CAPG2 ...
