Recycling‐Induced Changes of Molecular Weight and Structural Properties in PET Monopolymer Blends

open access: yesJournal of Polymer Science, EarlyView.
The present study investigates the molecular weight, thermal, rheological, and mechanical properties of polymer blends of high and low molecular weight polyethylene terephthalate (PET) components. The research reveals that extrusion processing influences chain scission and chain extension, inhibiting the broadening of the molecular weight distribution ...

Status and future of seed conservation of threatened plants in the post‐2020 era

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Ambitious targets have been set to backup seeds of threatened plants by the global strategy for plant conservation (GSPC), but it is unclear in how far these targets have been met and how seed collection should be organized to meet future challenges. Here, we provide an overview of the status of 44 countries in achieving seed conservation targets.

Relationship between food quality and body size of common vole in different habitats

open access: yesPest Management Science, EarlyView.
The body size of the common vole in crop fields (alfalfa, rape, cereals) is larger than in less‐cultivated habitats (forests, clearings, set‐aside) and is not related to food quality. Abstract BACKGROUND There is a close relationship between habitat, food and demographic parameters of common vole populations.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.
