Overview

Rasmus Ejrnæs is affiliated with Aarhus University in Denmark and has contributed extensively to environmental science and agricultural and biological sciences. Their research spans numerous subfields, including ecology, nature and landscape conservation, ecology, evolution, behavior and systematics, global and planetary change, and ecological modeling.

Their work has been published in several frequent venues, such as bioRxiv (Cold Spring Harbor Laboratory), Oikos, AMBIO, Applied Vegetation Science, and the Journal of Applied Ecology.

Ejrnæs has worked collaboratively with several co-authors, notably Camilla Fløjgaard, Hans Henrik Bruun, Tobias Guldberg Frøslev, Ane Kirstine Brunbjerg, and Lars Dalby. Their joint research has produced multiple studies across diverse ecological topics.

Among recent papers, notable titles include:

  • Exploring a natural baseline for large-herbivore biomass in ecological restoration (2021, Journal of Applied Ecology)
  • The biodiversity effect of reduced tillage on soil microbiota (2021, AMBIO)
  • Detecting flying insects using car nets and DNA metabarcoding (2021, Biology Letters)
  • ReSurveyEurope: A database of resurveyed vegetation plots in Europe (2024, Journal of Vegetation Science)
  • Dark diversity reveals importance of biotic resources and competition for plant diversity across habitats (2020, Ecology and Evolution)

The main research topics covered include ecology and vegetation dynamics studies, plant and animal studies, peatlands and wetlands ecology, species distribution and climate change, environmental DNA in biodiversity studies, forest ecology and biodiversity studies, and environmental philosophy and ethics.

Ejrnæs is also an author of book publications, having published with Johns Hopkins University. One of the titles is Byens grønne struktur: Natur og miljø i bylandskabet (2023).
