Overview

What is she best known for?

The fields of study she is best known for:

  • Ecology
  • IUCN Red List
  • Habitat

Colleen T. Downs focuses on Ecology, Botany, Sugar, Zoology and Animal science. Her Ecology study frequently draws parallels with other fields, such as Basal metabolic rate. Her Botany study incorporates themes from Ingestion, Seed dispersal and Frugivore.

Her Sugar research incorporates themes from Nectar and Sucrose. Her Zoology research is multidisciplinary, relying on both Thermoregulation, Thermal neutral zone, Nocturnal and Reproductive success. Her Animal science study which covers Energy balance that intersects with Nutrient, Assimilation and Zosterops pallidus.

Her most cited work include:

  • Impact of protection on nest take and nesting success of parrots in Africa, Asia and Australasia (58 citations)
  • Self-Assessment and the Disadvantaged Student: Potential for Encouraging Self-Regulated Learning?. (52 citations)
  • A survey of wildlife rehabilitation in South Africa: is there a need for improved management? (47 citations)

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

Her primary areas of study are Ecology, Habitat, Zoology, Frugivore and Botany. Her study in Predation, Endangered species, Range, Home range and Nest is carried out as part of her studies in Ecology. The Habitat study combines topics in areas such as Biodiversity, Occupancy, Urbanization, Species richness and Foraging.

Colleen T. Downs works mostly in the field of Zoology, limiting it down to concerns involving Basal metabolic rate and, occasionally, Thermoregulation. Her Frugivore research incorporates elements of Biological dispersal, Seed dispersal and Germination, Horticulture. Colleen T. Downs combines subjects such as Sugar, Animal science and Sucrose with her study of Botany.

She most often published in these fields:

  • Ecology (58.84%)
  • Habitat (21.37%)
  • Zoology (18.21%)

What were the highlights of her more recent work (between 2018-2021)?

  • Ecology (58.84%)
  • Habitat (21.37%)
  • Zoology (18.21%)

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

Ecology, Habitat, Zoology, Biodiversity and Fishery are her primary areas of study. Many of her studies on Ecology apply to Biological dispersal as well. Her research in Biological dispersal intersects with topics in Frugivore, Germination, Horticulture and Invasive species.

Her study in the field of Riparian zone also crosses realms of Context. Her work carried out in the field of Fishery brings together such families of science as Eagle and Apex predator. While the research belongs to areas of Species richness, she spends her time largely on the problem of Disturbance, intersecting her research to questions surrounding Wildlife.

Between 2018 and 2021, her most popular works were:

  • Drivers of fine-scale avian functional diversity with changing land use: an assessment of the effects of eco-estate housing development and management (12 citations)
  • Anthropogenic influences on the time budgets of urban vervet monkeys. (12 citations)
  • Fragment and life‐history correlates of extinction vulnerability of forest mammals in an urban‐forest mosaic in EThekwini Municipality, Durban, South Africa (10 citations)

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

  • Ecology
  • IUCN Red List
  • Habitat

Colleen T. Downs spends much of her time researching Ecology, Habitat, Wildlife, Biodiversity and Species richness. Her work in Resource, Endangered species, Ecological niche, Competition and Habitat destruction are all subfields of Ecology research. Her study on Urban wildlife is often connected to Metropolitan area, Relative risk and Conceptual model as part of broader study in Habitat.

Her study looks at the intersection of Wildlife and topics like Disturbance with Time budget, Foraging and Vegetation. Her Biodiversity study combines topics in areas such as Agroforestry and Biological dispersal. The concepts of her Species richness study are interwoven with issues in Land use, Generalist and specialist species and Ecosystem, Ecosystem services.
