The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1200-1258, November 2025.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Microstructural and geochemical evidence offers a solution to the cephalopod cameral deposits riddle

open access: yesPalaeontology, Volume 68, Issue 6, November/December 2025.
Abstract Orthoceratoid cephalopods are common in the Palaeozoic rock record but went extinct in the Late Triassic. Many orthoceratoids contain cameral deposits, which are enigmatic calcareous structures within their chambered shell that presumably balanced their straight conchs in a horizontal position. Since the mid‐19th century, palaeontologists have

The Bug‐Network (BugNet): A Global Experimental Network Testing the Effects of Invertebrate Herbivores and Fungal Pathogens on Plant Communities and Ecosystem Function in Open Ecosystems

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
The Bug‐Network (BugNet) is a novel global collaborative research network that implements standardized consumer‐reduction experiments in herbaceous‐ or shrub‐dominated ecosystems to assess the impacts of invertebrate herbivores and fungal pathogens on plant communities and ecosystem functioning.

Predicting long-term recovery of a strongly acidified stream using MAGIC and climate models (Litavka, Czech Republic) [PDF]

open access: yes, 2007
Two branches forming the headwaters of a stream in the Czech Republic were studied. Both streams have similar catchment characteristics and historical deposition; however one is rain-fed and strongly affected by acid atmospheric deposition, the other ...

A comparison of survivourship and function (grazing and behaviour) of three gastropod species used as clean-up crew for the marine aquarium trade [PDF]

open access: yes, 2018
Several million gastropods are collected each year for the marine ornamental trade to graze on algae detrimental to aquarium species, however, little is known about popular species' suitability to perform this clean-up crew role.

Effects of Static and Low‐Frequency Magnetic Fields on Gene Expression

open access: yesJournal of Magnetic Resonance Imaging, Volume 62, Issue 2, Page 317-334, August 2025.
Substantial research over the past two decades has established that magnetic fields affect fundamental cellular processes, including gene expression. However, since biological cells and subcellular components exhibit diamagnetic behavior and are therefore subjected to very small magnetic forces that cannot directly compete with the viscoelastic and ...

New osteological characteristics identify the first stem sleeper goby (Gobioidei, Odontobutidae) from the upper Eocene

open access: yesPapers in Palaeontology, Volume 11, Issue 4, July/August 2025.
Abstract Among the Gobioidei, one of the most diverse orders of teleost fishes, the families Odontobutidae (sleeper gobies) and Rhyacichthyidae are considered ‘basal gobioids’ and are therefore particularly interesting for understanding gobioid evolutionary history.
