Overview

Christoph Randler is affiliated with the University of Tübingen in Germany. Their research spans multiple disciplines including psychology and environmental science, focusing on areas such as social psychology, experimental and cognitive psychology, health toxicology, ecology, and ecological modeling.

Their work explores various topics including urban green space and health, animal and plant science education, recreation and wilderness management, species distribution and climate change, sleep and related disorders, animal behavior and reproduction, as well as plant and animal studies.

Randler has contributed to a number of scientific publications. Some recent papers include:

  • "Fostering pre-service teachers' technological pedagogical content knowledge (TPACK): A quasi-experimental field study," 2021, Computers & Education
  • "SARS-CoV2 (COVID-19) Pandemic Lockdown Influences Nature-Based Recreational Activity: The Case of Birders," 2020, International Journal of Environmental Research and Public Health
  • "Changes in sleep schedule and chronotype due to COVID-19 restrictions and home office," 2020, Somnologie - Schlafforschung und Schlafmedizin
  • "Animal Welfare Attitudes: Effects of Gender and Diet in University Samples from 22 Countries," 2021, Animals
  • "Users of a citizen science platform for bird data collection differ from other birdwatchers in knowledge and degree of specialization," 2021, Global Ecology and Conservation

Randler's publications frequently appear in these venues:

  • Animals
  • Chronobiology International
  • Birds
  • Somnologie - Schlafforschung und Schlafmedizin
  • International Journal of Science Education

They collaborate regularly with several coauthors who have contributed extensively alongside them. Frequent coauthors include:

  • Talia Härtel
  • Naomi Staller
  • Nadine Kalb
  • Janina Vanhöfen
  • Piotr Tryjanowski

Randler's research touches on intersecting fields that relate human behavior and health to environmental and ecological factors. Their work on sleep patterns, especially in the context of COVID-19 restrictions, addresses shifts in chronotype and daily rhythms, contributing to understanding behavioral adaptations during the pandemic.

Research on animal welfare attitudes and biodiversity engagement, such as the study of citizen science participants versus general birdwatchers, indicates a focus on the relationship between humans and nature through educational and recreational lenses. The intersection of health, psychology, ecology, and education forms a core component of their scholarly output.
