Overview

Ørjan Totland is affiliated with the Norwegian University of Life Sciences in Norway. Their research primarily centers on Agricultural and Biological Sciences, with significant contributions in several subfields including Ecology, Evolution, Behavior and Systematics, Atmospheric Science, Insect Science, Plant Science, and Molecular Biology.

The scientist's work encompasses a range of main topics such as Plant and Animal Studies, Plant Reproductive Biology, Climate Change and Permafrost, Tree-ring Climate Responses, Plant Water Relations and Carbon Dynamics, Insect and Pesticide Research, and Insect and Arachnid Ecology and Behavior.

Ørjan Totland has published research in various academic venues, including Nature Communications, Scientific Reports, Ecological Applications, Ecology and Evolution, and Basic and Applied Ecology. The recent published papers include:

  • Experimental warming differentially affects vegetative and reproductive phenology of tundra plants (2021, Nature Communications)
  • Disentangling direct and indirect effects of habitat fragmentation on wild plants' pollinator visits and seed production (2020, Ecological Applications)
  • Forest fragmentation modifies the composition of bumblebee communities and modulates their trophic and competitive interactions for pollination (2020, Scientific Reports)
  • Enhancing pollination is more effective than increased conventional agriculture inputs for improving watermelon yields (2020, Ecology and Evolution)
  • Inadequate pollination services limit watermelon yields in northern Tanzania (2020, Basic and Applied Ecology)

Collaboration is an important aspect of their work, with frequent co-authors including Katrine Eldegard, Kari Klanderud, Amparo Lázaro, Thomas Sawe, and Samora A. Macrice. These frequent partnerships indicate active engagement in multi-author, interdisciplinary research efforts.
