Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Habitat
  • Predation

Raymond H. G. Klaassen focuses on Ecology, Biological sciences, Satellite tracking, Climate change and Satellite telemetry. His study in Bird migration and Annual cycle falls within the category of Ecology. His Bird migration research includes elements of Foraging and Habitat.

Borrowing concepts from Marsh harrier, Raymond H. G. Klaassen weaves in ideas under Satellite tracking. The concepts of his Climate change study are interwoven with issues in Abundance, Resource and Songbird. His research integrates issues of Animal migration, Direct evidence, Total mortality and Annual variation in his study of Satellite telemetry.

His most cited work include:

  • When and where does mortality occur in migratory birds? Direct evidence from long- term satellite tracking of raptors (259 citations)
  • When and where does mortality occur in migratory birds? Direct evidence from long- term satellite tracking of raptors (259 citations)
  • Geolocation by light: accuracy and precision affected by environmental factors (196 citations)

What are the main themes of his work throughout his whole career to date?

Raymond H. G. Klaassen mostly deals with Ecology, Foraging, Habitat, Bird migration and Annual cycle. By researching both Ecology and Biological sciences, he produces research that crosses academic boundaries. The study incorporates disciplines such as Circus pygargus, Spatial heterogeneity and Nest in addition to Foraging.

His Habitat research includes themes of Harrier and Biodiversity. As a member of one scientific family, Raymond H. G. Klaassen mostly works in the field of Bird migration, focusing on Fishery and, on occasion, Gallinago. His Annual cycle research is multidisciplinary, incorporating elements of Overwintering, Environmental change, Seasonality, Passerine and Normalized Difference Vegetation Index.

He most often published in these fields:

  • Ecology (76.40%)
  • Foraging (25.84%)
  • Habitat (23.60%)

What were the highlights of his more recent work (between 2018-2020)?

  • Ecology (76.40%)
  • Habitat (23.60%)
  • Foraging (25.84%)

In recent papers he was focusing on the following fields of study:

His main research concerns Ecology, Habitat, Foraging, Range and Phenology. Ecology is a component of his Climate change, Wader, Threatened species, Food availability and Avian clutch size studies. His Climate change research is multidisciplinary, relying on both Snow and Phalaropus lobatus.

Raymond H. G. Klaassen has included themes like Invertebrate, Biodiversity, Vegetation and Temperate climate in his Habitat study. His Foraging study incorporates themes from Flyway and Fishery. His Range research integrates issues from Animal migration, Annual cycle and Lanius collurio, Shrike.

Between 2018 and 2020, his most popular works were:

  • A Migratory Divide Among Red-Necked Phalaropes in the Western Palearctic Reveals Contrasting Migration and Wintering Movement Strategies (6 citations)
  • Chapter Four - Integrating biodiversity conservation in wider landscape management: Necessity, implementation and evaluation (5 citations)
  • Collision risk of Montagu's Harriers Circus pygargus with wind turbines derived from high‐resolution GPS tracking (4 citations)

In his most recent research, the most cited papers focused on:

  • Ecology
  • Habitat
  • Predation

Raymond H. G. Klaassen mainly investigates Habitat, Renewable energy, Circus pygargus, Meteorology and Population size. His Habitat research is classified as research in Ecology. Renewable energy is connected with Repowering, Turbine and Range in his research.
