Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Gene
  • Natural selection

Fredric J. Janzen spends much of his time researching Ecology, Sex ratio, Painted turtle, Natural selection and Temperature-dependent sex determination. Hatchling, Nest, Predation, Habitat and Adaptation are the subjects of his Ecology studies. Specifically, his work in Sex ratio is concerned with the study of Environmental sex determination.

The study incorporates disciplines such as Aridification and Sperm competition in addition to Painted turtle. His Natural selection research is multidisciplinary, relying on both Chelydra, Bayesian multivariate linear regression and Evolutionary change. His work carried out in the field of Temperature-dependent sex determination brings together such families of science as Taxon and Climate change.

His most cited work include:

  • Visualizing and quantifying natural selection (541 citations)
  • ENVIRONMENTAL SEX DETERMINATION IN REPTILES: ECOLOGY, EVOLUTION, AND EXPERIMENTAL DESIGN (395 citations)
  • Climate change and temperature-dependent sex determination in reptiles (390 citations)

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

His main research concerns Ecology, Painted turtle, Zoology, Nest and Turtle. Ecology is closely attributed to Temperature-dependent sex determination in his study. His research in Painted turtle intersects with topics in Ectotherm, Climate change, Nesting and Sex ratio.

His Zoology research focuses on subjects like Chelydra, which are linked to Yolk. He has included themes like Phenotypic plasticity and Maternal effect in his Nest study. His work deals with themes such as Natural selection and Selection, which intersect with Predation.

He most often published in these fields:

  • Ecology (65.82%)
  • Painted turtle (37.76%)
  • Zoology (30.10%)

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

  • Painted turtle (37.76%)
  • Zoology (30.10%)
  • Ecology (65.82%)

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

Fredric J. Janzen focuses on Painted turtle, Zoology, Ecology, Turtle and Nest. His Painted turtle research integrates issues from Temperature-dependent sex determination, Sex ratio and Abiotic component. The concepts of his Zoology study are interwoven with issues in Overwintering, Hormone, Corticosterone and photoperiodism.

His Nesting, Microclimate and Local adaptation study, which is part of a larger body of work in Ecology, is frequently linked to Variation and Soil temperature, bridging the gap between disciplines. His study looks at the relationship between Turtle and fields such as Egg incubation, as well as how they intersect with chemical problems. His Nest research includes elements of Temporal scales, Effects of global warming, Predation and Hatchling.

Between 2017 and 2021, his most popular works were:

  • Adaptive responses of animals to climate change are most likely insufficient (96 citations)
  • Female lizards choose warm, moist nests that improve embryonic survivorship and offspring fitness (18 citations)
  • Altered spring phenology of North American freshwater turtles and the importance of representative populations (15 citations)

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

  • Ecology
  • Gene
  • Extinction

Fredric J. Janzen mostly deals with Painted turtle, Ecology, Evolutionary biology, Trait and Turtle. His studies in Painted turtle integrate themes in fields like Zoology, Local adaptation and Longevity. Fredric J. Janzen does research in Ecology, focusing on Hatchling specifically.

Fredric J. Janzen has researched Hatchling in several fields, including Maternal effect, Reproduction, Sexual maturity, Nest and Survivorship curve. His Evolutionary biology research incorporates elements of Phenotypic trait and Evolutionary ecology. His Turtle research incorporates themes from Coi gene and Environmental DNA.
