Effects of Predator Species and Size on Prey Escape Success Through the Digestive Tract

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Adults of the aquatic beetle Regimbartia attenuata can survive passage through the digestive tracts of six predator (frog) species, including a non‐native bullfrog. Their active movement through the gut likely facilitates their escape through the cloaca, irrespective of predator species or size.

The nicotinamide hypothesis revisited—plant defense signaling integrating PARP, nicotinamide, nicotinic acid, epigenetics, and glutathione

open access: yesFEBS Letters, Volume 599, Issue 22, Page 3355-3368, November 2025.
Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Optimal Environmental DNA Sampling Strategy for Comprehensively Assessing Biodiversity in Rice Paddy Fields

open access: yesEnvironmental DNA, Volume 7, Issue 6, November–December 2025.
ABSTRACT Irrigated paddy fields provide alternative habitats for aquatic species amid degrading natural wetland habitats. Paddy field biodiversity depends on surrounding landscapes and agricultural practices, and biodiversity surveys are important in understanding it. However, its assessment is often time‐consuming and depends on specialist skills.
