Pond frog as a predator of hornet workers: High tolerance to venomous stings

open access: yesEcosphere, Volume 16, Issue 12, December 2025.
Abstract Some animals use stingers to repel attackers, and some predators have evolved tolerance to such stings, enabling them to consume venomous prey. For example, social wasps, such as hornets, use modified ovipositors as venomous stingers to inject venom, which can cause intense pain in humans.

Synopsis of Nekemias Raf., a segregate genus from Ampelopsis Michx. (Vitaceae) disjunct between eastern/southeastern Asia and eastern North America, with ten new combinations

open access: yesPhytoKeys, 2014
The genus Nekemias (Vitaceae) was first recognized by Rafinesque in 1838. It has been treated as a synonym of Ampelopsis Michx. Recent phylogenetic studies suggest that Ampelopsis as traditionally delimited is paraphyletic.

CPOP1 is a key enzyme required for nodule microenvironment control and successful symbiotic nitrogen fixation in Lotus japonicus

open access: yesJournal of Integrative Plant Biology, Volume 67, Issue 12, Page 3167-3181, December 2025.
The enzyme coproporphyrinogen III oxidase plastid related 1 (CPOP1) creates a low‐oxygen nodule environment for nitrogen fixation within nodules of Lotus japonicus. CPOP1 makes heme, which helps control oxygen, and acts in infected cells; its knockout raises oxygen levels, suppresses nitrogen‐fixing enzyme activity, and halts nitrogen fixation ...

Deconstruction of the (paleo)polyploid grapevine genome based on the analysis of transposition events involving NBS resistance genes. [PDF]

open access: yesPLoS ONE, 2012
Plants have followed a reticulate type of evolution and taxa have frequently merged via allopolyploidization. A polyploid structure of sequenced genomes has often been proposed, but the chromosomes belonging to putative component genomes are difficult to

Automated identification of honey bee pollen loads for field‐applied palynological studies

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1584-1599, November 2025.
Summary In a changing world, it is crucial to characterise communities and their evolution over time. Because social insect pollinators forage on flowering plants around the colony, the nest potentially contains important information about the pollinated plants such as species identity and plant phenology.
