  • 2011 - George Mercer Award, The Ecological Society of America

Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Genetics
  • Predation

Tracy Langkilde spends much of his time researching Ecology, Zoology, Lizard, Invasive species and Fire ant. In the subject of general Zoology, his work in Courtship, Thamnophis sirtalis and Autotomy is often linked to Ethics committee, thereby combining diverse domains of study. His Courtship research is multidisciplinary, incorporating perspectives in Sexual selection and Mate choice, Mating.

His Lizard study integrates concerns from other disciplines, such as Thermoregulation, Dominance, Dorsum and Crypsis. His research in Invasive species intersects with topics in Red imported fire ant, Immune system, Predator and Introduced species. The various areas that he examines in his Fire ant study include Ecoimmunology, Innate immune system and Threatened species.

His most cited work include:

  • How much stress do researchers inflict on their study animals? A case study using a scincid lizard, Eulamprus heatwolei. (175 citations)
  • Why did the snake cross the road? Effects of roads on movement and location of mates by garter snakes (Thamnophis sirtalis parietalis) (107 citations)
  • Invasive fire ants alter behavior and morphology of native lizards. (99 citations)

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

His scientific interests lie mostly in Ecology, Zoology, Lizard, Predation and Fire ant. His Ecology study focuses mostly on Introduced species, Invasive species, Intraspecific competition, Habitat and Adaptation. His study in Intraspecific competition is interdisciplinary in nature, drawing from both Eulamprus, Egernia and Sympatric speciation.

His studies in Courtship, Thamnophis sirtalis, Mating, Sexual selection and Mate choice are all subfields of Zoology research. Tracy Langkilde focuses mostly in the field of Lizard, narrowing it down to topics relating to Corticosterone and, in certain cases, Glucocorticoid and Immune system. His work on Predator is typically connected to Tadpole as part of general Predation study, connecting several disciplines of science.

He most often published in these fields:

  • Ecology (56.92%)
  • Zoology (42.31%)
  • Lizard (37.69%)

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

  • Zoology (42.31%)
  • Lizard (37.69%)
  • Corticosterone (14.62%)

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

Tracy Langkilde focuses on Zoology, Lizard, Corticosterone, Fire ant and Glucocorticoid. The Mating research Tracy Langkilde does as part of his general Zoology study is frequently linked to other disciplines of science, such as Vertebrate, therefore creating a link between diverse domains of science. His studies in Lizard integrate themes in fields like Oviparity, Endocrinology and Noise.

His study in the field of Plasma corticosterone is also linked to topics like Future studies. His biological study spans a wide range of topics, including Predator and Invasive species. Predation is the subject of his research, which falls under Ecology.

Between 2018 and 2021, his most popular works were:

  • Obtaining plasma to measure baseline corticosterone concentrations in reptiles: How quick is quick enough? (10 citations)
  • Contrasting Responses of Lizards to Divergent Ecological Stressors Across Biological Levels of Organization. (8 citations)
  • Population history with invasive predators predicts innate immune function response to early-life glucocorticoid exposure in lizards (6 citations)

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

  • Ecology
  • Genetics
  • Zoology

Zoology, Lizard, Corticosterone, Glucocorticoid and Immune system are his primary areas of study. Tracy Langkilde studies Captivity which is a part of Zoology. Tracy Langkilde combines subjects such as Oviparity and Noise with his study of Lizard.

Tracy Langkilde merges many fields, such as Corticosterone and Future studies, in his writings. His work carried out in the field of Glucocorticoid brings together such families of science as Expression and Baseline level. His Immune system research is multidisciplinary, incorporating elements of Organism, Juvenile, Hormone and Fire ant.
