Impoverished meadow and forest flora threaten insects

The intensification of land use poses a major threat to biodiversity, including herbivorous insects and their host plants. If beetles, Orthoptera (grasshoppers/crickets), Heteroptera (true bugs) and Auchenorrhyncha (cicadas/leafhoppers/treehoppers/planthoppers/spittlebugs) ...

Researchers generate human-monkey chimeric embryos

Investigators in China and the United States have injected human stem cells into primate embryos and were able to grow chimeric embryos for a significant period of time—up to 20 days. The research, despite its ethical concerns, ...

North American deserts are a biodiversity hotspot for butterflies

By comparing the genetic diversity of butterflies in North America, researchers reporting in the journal iScience on March 23 found that the array of different evolutionary distinct groups of butterflies is particularly high ...

Ecological interactions as a driver of evolution

In a recent study, an international team of researchers including TUD botanist Prof. Stefan Wanke has investigated the origin of the mega-diversity of herbivorous insects. These account for a quarter of terrestrial diversity. ...

Cabbage whites triggered egg-killing leaf necrosis in crucifers

Until now, little was known about how plants protect themselves from plant-eating insects and how the arms race between insects and plants unfolded. Researchers from Wageningen University & Research have gained more insight ...
