The amino terminal domain of the human α7 nicotinic acetylcholine receptor subunit leads to the functional expression of human/insect receptors

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 13, Page 3517-3537, July 2026.
Human α7 receptors have been characterised in terms of pharmacological properties. Insertion of the N‐terminal domain of the human α7 subunit leads to honeybee and cockroach chimeric receptors activated by ACh and inhibited by α‐Bgt. Insertion of the human cys‐loop leads to cockroach chimeric receptors modulated by PNU.

Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

open access: yesNew Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Frugivore Declines Across Taxa Affect Forest Biomass

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
We examined how frugivore declines affect aboveground biomass in 260 1‐ha forest plots across Gabon using imputed frugivory networks between 122 frugivores and 99,349 trees. Simulated frugivore declines across Gabon tended to reduce aboveground biomass, with effects varying by taxon and geography.

When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

open access: yesPeople and Nature, Volume 8, Issue 6, Page 1957-1973, June 2026.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

From pollen provision to pollinator: Species‐specific sterol assimilation by wild bees in urban landscapes

open access: yesFunctional Ecology, Volume 40, Issue 6, Page 1906-1920, June 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Human‐driven landscape change, particularly urbanization, is reshaping pollinator communities, yet the functional traits that mediate species persistence remain poorly understood. Dietary specialization is commonly used to predict species vulnerability.
