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

The scientist’s investigation covers issues in Ecology, Environmental resource management, Biodiversity, Habitat and Agroforestry. His study ties his expertise on Population growth together with the subject of Ecology. His Environmental resource management research also works with subjects such as

  • Ecosystem services, which have a strong connection to Land use,
  • Agricultural policy most often made with reference to Land management.

His work deals with themes such as Agricultural productivity, Ecosystem and Vegetation, which intersect with Biodiversity. His work carried out in the field of Habitat brings together such families of science as Spatial heterogeneity, Field and Species diversity. His Abundance research is multidisciplinary, incorporating elements of Alauda, Environmental change, Generalist and specialist species and Survey data collection.

He most often published in these fields:

  • Ecology (44.59%)
  • Environmental resource management (30.57%)
  • Biodiversity (28.03%)

What were the highlights of his more recent work (between 2017-2021)?

  • Biodiversity (28.03%)
  • Ecology (44.59%)
  • Ecosystem services (10.83%)

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

Gavin M. Siriwardena mostly deals with Biodiversity, Ecology, Ecosystem services, Habitat and Species richness. His Biodiversity research is multidisciplinary, incorporating perspectives in Range, Resource, Crop, Environmental protection and Agriculture. His study in Ecology focuses on Foraging in particular.

The various areas that Gavin M. Siriwardena examines in his Ecosystem services study include Urbanization, Urban ecosystem, Land use and Environmental planning. His Habitat research incorporates themes from Spatial analysis, Spatial heterogeneity and Woodland. Gavin M. Siriwardena has included themes like Freshwater ecosystem, Abundance and Vegetation in his Species richness study.

Between 2017 and 2021, his most popular works were:

  • Increasing crop heterogeneity enhances multitrophic diversity across agricultural regions (78 citations)
  • Landscape configurational heterogeneity by small-scale agriculture, not crop diversity, maintains pollinators and plant reproduction in western Europe (72 citations)
  • Small Water Bodies in Great Britain and Ireland: Ecosystem function, human-generated degradation, and options for restorative action (33 citations)

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

  • Ecology
  • Agriculture
  • Biodiversity

His primary scientific interests are in Biodiversity, Ecology, Ecosystem services, Agriculture and Crop. His Biodiversity research is multidisciplinary, relying on both Abundance, Resource and Species richness. His studies in Abundance integrate themes in fields like Environmental planning, Urban ecosystem and Wildlife management.

Gavin M. Siriwardena does research in Ecology, focusing on Foraging specifically. His Ecosystem services research includes elements of Environmental change, Riparian zone and Environmental protection. In his study, Competition, Habitat destruction, Gamma diversity and Alpha diversity is inextricably linked to Agroforestry, which falls within the broad field of Agriculture.
