Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

open access: yesAmerican Journal of Botany, Volume 113, Issue 8, August 2026.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Temporal Shifts in Subtidal Rocky Benthic Communities Associated With the Invasion of Rugulopteryx okamurae in a Port Environment

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 8, August 2026.
ABSTRACT The invasive brown alga Rugulopteryx okamurae, native to the northwestern Pacific, has rapidly expanded along the European Atlantic coast, reaching the Basque Coast in 2023, and was likely already present in 2022. Using annual data from a monitoring survey conducted between 2010 and 2025, this study assesses the spatio‐temporal variability of ...

Valorization of Ficus carica Pruning Residues as Selective Botanical Insecticides: Optimized Furanocoumarin Extraction, Efficacy Against Neotropical Stink Bugs, and Mechanistic Insights via Molecular Docking

open access: yesArchives of Insect Biochemistry and Physiology, Volume 122, Issue 4, August 2026.
Optimized extracts from Ficus carica pruning waste exhibit strong biological activity against major stink bug pests. Complementary in silico analyses suggest this efficacy relies on pest‐specific acetylcholinesterase inhibition, predicting a promising, pollinator‐safe alternative for sustainable agriculture.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, Volume 101, Issue 4, Page 1760-1778, August 2026.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Natural Photosensitizers in Cancer Therapy: A Chemo‐Biodiversity Perspective on Light‐Activated Natural Compounds

open access: yesChemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Natural photosensitizers, shaped by chemo‐biodiversity and evolution, offer diverse photoactive scaffolds for PDT. This review highlights their structure–activity relationships, photophysical properties, and nanotechnology‐based strategies to enhance efficacy, while addressing translational challenges and demonstrating how nature's molecular diversity ...

Cattle and bison grazing decreases monarch egg and larval abundance in the Central United States

open access: yesEcosphere, Volume 17, Issue 8, August 2026.
Abstract Monarch butterflies have experienced massive population declines and have been proposed to be listed as threatened under the U.S. Endangered Species Act. Milkweeds (Asclepias spp.) are the sole host plant for monarch larvae, and milkweed abundance has dramatically declined in the past 25 years due to increased usage of herbicides and the ...

Metabolite Variations in Lepidium sativum Seeds Among Different Germplasms: Unraveling the Link Between Environment and Chemical Compounds

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Comparative phytochemical analysis of Lepidium sativum seed populations revealed environmentally driven variation in essential oil composition, while fatty acid profiles remained largely stable across populations. Benzyl nitrile was the dominant essential oil constituent, α‐linolenic acid was the major fatty acid, and all populations exhibited weak ...
