Fischer has several recent publications highlighting various aspects of biodiversity, genetics, and ecology. These include:

  • Biodiversity in agricultural landscapes: Grassy field margins and semi-natural fragments both foster spider diversity and body size (2021, Agriculture Ecosystems & Environment)
  • Biodiversity in agricultural landscapes: different non-crop habitats increase diversity of ground-dwelling beetles (Coleoptera) but support different communities (2021, Biodiversity and Conservation)
  • Plant-mediated indirect effects of climate change on an insect herbivore (2021, Basic and Applied Ecology)
  • Anthropogenic and natural barriers affect genetic connectivity in an Alpine butterfly (2020, Molecular Ecology)
