• Palearctic passerine migrant declines in African wintering grounds in the Anthropocene (1970–1990 and near future): a conservation assessment using publicly available GIS predictors and machine learning 

  Walther, B.A.; Huettmann, F. (2021)

  The Anthropocene causes many massive and novel impacts, e.g., on migratory birds and their habitats. Many species of migratory birds have been declining on the Palearctic-African flyway in recent decades. To investigate ...

• Source pools and disharmony of the world's island floras 

  König, C.; Weigelt, P.; Taylor, A.; Stein, A.; Dawson, W.; Essl, F.; Pergl, J.; Pyšek, P.; van Kleunen, M.; Winter, M.; Chatelain, C.; Wieringa, J.J.; Krestov, P.; Kreft, H. (2021)

  Island disharmony refers to the biased representation of higher taxa on islands compared to their mainland source regions and represents a central concept in island biology. Here, we develop a generalizable framework for ...

• Complex responses of global insect pests to climate warming 

  Lehmann, P.; Ammunet, T.; Barton, M.; Battisti, A.; Eigenbrode, S.D.; Jepsen, J.U.; Kalinkat, G.; Neuvonen, S.; Niemela, P.; Terblanche, J.S.; Okland, B.; Bjorkman, C. (2020)

  Although it is well known that insects are sensitive to temperature, how they will be affected by ongoing global warming remains uncertain because these responses are multifaceted and ecologically complex. We reviewed the ...
