Warming Reduces Parasitoid Success and Narrows Their Diet Breadth
Warming may have a major impact on trophic networks, but few interactions are typically studied. Here we show that experimental warming strongly decreased the success of parasitoid development across...

Trophic rewilding depends on the assumption that replacing lost megafauna with alternative species can generate similar benefits. This new review by Bescond-Michel et al. challenges that belief. 🌏🌐🧪
Harms of introduced large herbivores outweigh benefits to native biodiversity - Nature Communications
Using impact assessment frameworks, this study shows that the introduction of large mammalian herbivores outside their native range has predominantly caused negative impacts on native biodiversity globally. The authors advise caution regarding their further intentional introduction for conservation purposes.
