Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Habitat
  • Zoology

Keith A. Hobson mainly focuses on Ecology, Trophic level, Isotope analysis, δ13C and Predation. He focuses mostly in the field of Ecology, narrowing it down to matters related to δ15N and, in some cases, Aptenodytes patagonicus. His study explores the link between Trophic level and topics such as Pelagic zone that cross with problems in Benthic zone.

His studies in Isotope analysis integrate themes in fields like Eumetopias jubatus, Isotopes of nitrogen, Clupea and Animal science. His δ13C study combines topics in areas such as Food chain, Monarch butterfly, Isotopic signature and Isotopes of carbon. As a part of the same scientific study, he usually deals with the Predation, concentrating on Foraging and frequently concerns with Range.

His most cited work include:

  • Tracing origins and migration of wildlife using stable isotopes: a review (1310 citations)
  • Assessing Avian Diets Using Stable Isotopes I: Turnover of 13C in Tissues (942 citations)
  • Linking Winter and Summer Events in a Migratory Bird by Using Stable-Carbon Isotopes (841 citations)

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

His main research concerns Ecology, Trophic level, Feather, Isotope analysis and δ13C. His Ecology research includes themes of Isoscapes and δ15N. His Trophic level research incorporates elements of Larus, Pelagic zone, Arctic and Seabird.

His biological study spans a wide range of topics, including Nutrient and Yolk. The Predation study combines topics in areas such as Foraging and Nest. His research in Habitat intersects with topics in Boreal and Taiga.

He most often published in these fields:

  • Ecology (98.72%)
  • Trophic level (20.44%)
  • Feather (20.44%)

What were the highlights of his more recent work (between 2013-2021)?

  • Ecology (98.72%)
  • Feather (20.44%)
  • δ15N (12.77%)

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

Keith A. Hobson spends much of his time researching Ecology, Feather, δ15N, δ13C and Range. His work in Ecology is not limited to one particular discipline; it also encompasses Isoscapes. Keith A. Hobson combines subjects such as Subspecies and Wet season with his study of Feather.

Keith A. Hobson works mostly in the field of δ15N, limiting it down to concerns involving Fishery and, occasionally, Mergus, Mergus squamatus and Brackish water. As part of one scientific family, Keith A. Hobson deals mainly with the area of δ13C, narrowing it down to issues related to the Environmental chemistry, and often Trace element. His research integrates issues of Overwintering, Habitat destruction, Phenology, Dry season and Flight feather in his study of Range.

Between 2013 and 2021, his most popular works were:

  • Rapidly increasing methyl mercury in endangered ivory gull (Pagophila eburnea) feathers over a 130 year record. (71 citations)
  • Connecting breeding and wintering grounds of Neotropical migrant songbirds using stable hydrogen isotopes: a call for an isotopic atlas of migratory connectivity (66 citations)
  • Differences in spatial synchrony and interspecific concordance inform guild-level population trends for aerial insectivorous birds (60 citations)

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

  • Ecology
  • Habitat
  • Zoology

His primary scientific interests are in Ecology, Feather, δ15N, Isoscapes and Trophic level. His Ecology study frequently links to related topics such as δ13C. His Feather research is multidisciplinary, incorporating perspectives in Hydrogen isotope, Bird conservation, Phylloscopus trochilus, Ficedula albicollis and Hybrid.

His Isoscapes research integrates issues from Opportunistic Sampling, Relative species abundance, Habitat, δ18O and Population level. His studies deal with areas such as Mercury, Cave bear, Foraging and Larus glaucescens as well as Trophic level. His studies in Food web integrate themes in fields like Arctic and Seabird.
