Overview

Hannu Pöysä is affiliated with the Natural Resources Institute Finland in Finland and specializes in Environmental Science with a substantial focus on Ecology. Their research primarily explores avian ecology and behavior alongside wildlife ecology and conservation, addressing topics such as species distribution and climate change, animal behavior and reproduction, fish ecology and management studies, plant and animal studies, and peatlands and wetlands ecology.

Their notable recent publications include:

  • Extending temporal baseline increases understanding of biodiversity change in European boreal waterbird communities, 2021, Biological Conservation
  • Local variation in the timing and advancement of lake ice breakup and impacts on settling dynamics in a migratory waterbird, 2021, The Science of The Total Environment

Additionally, they have contributed to studies led by other authors such as Lucyna Hałupka, Céline Arzel, and David J. Messmer, covering topics related to climate change impacts on avian offspring production, invertebrate declines in boreal aquatic habitats, and avian breeding timing plasticity in response to spring temperature.

Frequent coauthors collaborating with Hannu Pöysä include:

  • Sari Holopainen
  • Erkki Korpimäki
  • Petri Nummi
  • Veli-Matti Väänänen
  • Céline Arzel

Their research has been published most often in the following venues:

  • Ecology and Evolution
  • The Science of The Total Environment
  • Global Ecology and Conservation
  • Behavioral Ecology and Sociobiology
  • Journal of Avian Biology

Subfields contributing to their work include ecology, evolution, behavior and systematics, nature and landscape conservation, ecological modeling, and atmospheric science. Their contributions to science involve integrating multiple aspects of environmental and ecological dynamics, with specific attention to boreal aquatic ecosystems and avian species responses to environmental change.
