Overview

Raymond H. G. Klaassen is affiliated with the University of Groningen in the Netherlands and specializes in environmental science with a significant focus on avian ecology and behavior. Their work spans multiple interconnected fields, including ecology, ecological modeling, genetics, nature and landscape conservation, and broader studies in ecology, evolution, behavior, and systematics.

Their research covers a variety of main topics, notably:

  • Avian ecology and behavior
  • Species distribution and climate change
  • Wildlife ecology and conservation
  • Animal ecology and behavior studies
  • Ecology and vegetation dynamics studies
  • Animal behavior and reproduction
  • Wildlife-road interactions and conservation

Klaassen has contributed to several recent publications that highlight diverse aspects of bird migration, ecology, and methodologies for tracking and conservation. Key recent papers include:

  • Extreme altitude changes between night and day during marathon flights of great snipes, 2021, Current Biology
  • Ecological impact and cost-effectiveness of wildlife crossings in a highly fragmented landscape: a multi-method approach, 2020, Landscape Ecology
  • Evolution of chain migration in an aerial insectivorous bird, the common swift Apus apus, 2020, Evolution
  • Remarkably similar migration patterns between different red-backed shrike populations suggest that migration rather than breeding area phenology determines the annual cycle, 2020, Journal of Avian Biology
  • How to improve the accuracy of height data from bird tracking devices? An assessment of high-frequency GPS tracking and barometric altimetry in field conditions, 2023, Animal Biotelemetry

Frequent co-authors collaborating with Klaassen across multiple publications include:

  • Tonio Schaub
  • Kjell Janssens
  • Tanja Milotić
