Comparative lipidomic and proteomic analysis reveals species‐specific differences in midgut composition and insecticide absorption between Apis mellifera and Bombus terrestris

Pest Management Science, Volume 82, Issue 2, Page 1540-1551, February 2026.
Lipidomic and proteomic analysis revealed large‐scale differences in the midgut composition of the honeybee Apis mellifera and the buff‐tailed bumblebee Bombus terrestris. These differences correlated to increased insecticide absorption in the bumblebee when using an ex vivo Ussing chamber and subsequently in vivo feeding assay (created in Biorender ...

Advancing Water Security in the Tropical and Subtropical Regions: An Integrative Topic Modeling Approach

World Water Policy, Volume 12, Issue 1, February 2026.
ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

Active Transport of Carbon to Demersal Fish Communities in Shelf‐Slope‐Abyssal Systems of the North Atlantic Ocean

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.

Carbon Cycle Succession Across a Permafrost Thaw Gradient in Northeastern Alberta as Revealed by δ13C in Dissolved Solids, Gases, and Particulates in Lakes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract δ13C in particulate organic carbon (POC), dissolved organic carbon (DOC), dissolved inorganic carbon (DIC), carbon dioxide (CO2(g)) and methane (CH4(g)), together with geochemical modeling, were applied to describe carbon cycle evolution in 40 boreal lakes situated across a permafrost thaw gradient in northeastern Alberta, Canada, where ...

N2 fixation is linked to the ability to encroach in African savanna trees

Functional Ecology, Volume 40, Issue 2, Page 517-533, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Encroachment is a globally ubiquitous phenomenon, characterised by increasing indigenous tree densities in savanna and grassland. Encroachment has been attributed to rising atmospheric CO2 concentrations fertilising tree growth and shifting the competitive balance ...
