Unexpected Global Prevalence of Mesopelagic Particle Layers Detected by BGC‐Argo Floats

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Particulate organic carbon transported to the deep ocean forms a critical component of the Earth's carbon cycle. The concentration of these particles is generally parameterized in models to decrease continuously with depth, but isolated layers of small particles (≤ ${\le} $20 μm ${\upmu }\mathrm{m}$) observed within the mesopelagic challenge ...

Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Since the late 1950s, atrazine has been a cornerstone of corn (Zea mays L.) weed control, but decades of use have raised concerns about groundwater contamination and enhanced biodegradation. Therefore, amicarbazone and metribuzin were evaluated as alternatives to preemergence use of atrazine in corn.

Marine Functional Connectivity Contributes to Ecosystem Functioning Across Multiple Scales

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The passive transport and active movements of marine organisms between habitats and ecosystems, known as marine functional connectivity, play a critical role in the functioning of marine ecosystems. However, marine functional connectivity, particularly at large spatial scales, is often understudied, and consequently tends to be overlooked in ...

Contrasting Temporal Dynamics of Ostracod (Crustacea) Communities in Protected and Impacted Areas in a Brazilian Floodplain

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, Volume 309, Issue 9, Page 2286-2297, September 2026.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...
