Arthropods on native versus alien woody plants: Understanding variation across host plant taxonomy and geography

open access: yesEcosphere, Volume 17, Issue 5, May 2026.
Abstract Alien plants have generally been shown to support reduced arthropod abundance, biomass, and diversity compared to native plant species, but inferences have typically come from studies limited in taxonomic and geographic scope. Here, we make use of data from a unique citizen science project, Caterpillars Count!, that consists of nearly 70,000 ...

Effect of Insect Damage on Seed Germination of Black Locust (Robinia pseudoacacia)

open access: yesPlant Species Biology, Volume 41, Issue 3, May 2026.
As shown in the figure, the white‐circled black locust seeds absorbed water and swelled, whereas the red‐circled seeds remained unswollen. This observed cryptic seed heteromorphism in germination is likely attributable not only to the development of an impermeable seed coat during maturation but also to physical damage caused by insects. ABSTRACT Black

Turgor loss point explains climate‐driven growth reductions in trees in Central Europe

open access: yesPlant Biology, Volume 28, Issue 3, Page 732-737, April 2026.
Leaf turgor loss point of native tree species shows a high predictive power over the observed growth anomalies in Central Europe during the extensive drought period between 2018 and 2020. Abstract As climate change thrives, and the frequency of intense droughts is affecting many forested regions, a mechanistic understanding of the factors conferring ...

Wing and Pappus Appendages Decrease Seed Terminal Velocity: A Meta‐Analysis

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
This meta‐analysis integrated terminal velocity records for 1479 species from various sources and explored descriptive patterns by taxonomic group, seed dispersal vector, and seed appendage type. This study revealed that wing and pappus appendage decrease seed terminal velocity with a robust analysis using regression models to predict terminal velocity.
