Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Habitat
  • Predation

Hannu Pöysä mostly deals with Ecology, Habitat, Anatidae, Waterfowl and Biological sciences. Goldeneye, Anas crecca, Foraging, Predation and Precocial are the primary areas of interest in his Ecology study. In most of his Goldeneye studies, his work intersects topics such as Nest.

His work on Guild as part of general Habitat study is frequently linked to Diversity, therefore connecting diverse disciplines of science. His study looks at the relationship between Anatidae and fields such as Anas, as well as how they intersect with chemical problems. Hannu Pöysä has included themes like Density dependence, Resource, Population size and Competition in his Waterfowl study.

His most cited work include:

  • Group foraging, distance to cover and vigilance in the teal, Anas crecca (116 citations)
  • Resource Utilization Pattern and Guild Structure in a Waterfowl Community (96 citations)
  • Group foraging in patchy environments: the importance of coarse-level local enhancement (90 citations)

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

Hannu Pöysä mainly focuses on Ecology, Goldeneye, Anas, Anatidae and Habitat. His study in Predation, Nest, Brood, Waterfowl and Anas crecca falls within the category of Ecology. The Goldeneye study combines topics in areas such as Zoology, Precocial, Avian clutch size, Nest site and Hatching.

His research in Anas intersects with topics in Population density, Interspecific competition, Wigeon, Phenology and Foraging. His Anatidae study incorporates themes from Ecology and Competition. His Habitat study combines topics in areas such as Niche, Seasonal breeder, Vegetation and Boreal lakes.

He most often published in these fields:

  • Ecology (83.05%)
  • Goldeneye (36.44%)
  • Anas (27.12%)

What were the highlights of his more recent work (between 2011-2021)?

  • Ecology (83.05%)
  • Goldeneye (36.44%)
  • Predation (25.42%)

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

His primary areas of investigation include Ecology, Goldeneye, Predation, Anas and Anas crecca. His research in Habitat, Boreal, Wetland, Waterfowl and Nest are components of Ecology. He interconnects Density dependence, Anatidae and Physical geography in the investigation of issues within Waterfowl.

Hannu Pöysä combines subjects such as Brood, Perch and Life history theory with his study of Goldeneye. The study incorporates disciplines such as Predatory fish, Esox and Fishery in addition to Anas. His studies in Anas crecca integrate themes in fields like Juvenile, Eurasian wigeon, Wigeon and Diving duck.

Between 2011 and 2021, his most popular works were:

  • Effects of climate change on European ducks : what do we know and what do we need to know? (49 citations)
  • The importance of hunting pressure, habitat preference and life history for population trends of breeding waterbirds in Finland (45 citations)
  • Density dependence in ducks: a review of the evidence (27 citations)

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

  • Ecology
  • Habitat
  • Predation

His main research concerns Ecology, Anas, Anatidae, Zoology and Ecology. His study in Ecology concentrates on Phenology and Habitat. The various areas that Hannu Pöysä examines in his Anas study include Anas crecca, Fishery and Goldeneye.

His Goldeneye study frequently draws connections to adjacent fields such as Predation. His study in Anatidae is interdisciplinary in nature, drawing from both Conservation status, Avian clutch size and Waterfowl. His work on Brood as part of his general Zoology study is frequently connected to Drone and Wing, thereby bridging the divide between different branches of science.
