Johan Dahlgren

Johan Dahlgren is an Associate Professor in the Department of Biology at the University of Southern Denmark, with additional affiliations as CPop Associate Professor, PopBio Associate Professor, and member of the SDU Climate Cluster. His research profile shows extensive contributions to plant ecology, demography, and conservation biology with 46 research outputs including journal articles, book chapters, and datasets.

Dahlgren's research interests focus on plant demography, population dynamics of perennials and herbs, life history traits, orchid ecology, and the effects of climate change on plant populations. His work particularly examines how range size, population size, and environmental factors influence plant fitness, senescence, and conservation needs. The fingerprint analysis of his work shows strong emphasis on Population Dynamics (99%), Herbs (92%), Population Growth (88%), and Life History (74%) within Agricultural and Biological Sciences.

His recent publications demonstrate a focus on long-term plant demographic studies, climate change impacts on plant populations, and conservation implications of demographic patterns. Dahlgren's work often involves multi-year datasets and cross-species comparisons to understand fundamental patterns in plant population ecology.

Dahlgren has supervised multiple students and taught various courses including Plant Ecology (BB543), Pharmaceutical Biology (FA508), and Plants, Protists and Fungi (BB531). He has led significant research projects including 'SEAD-Plant: Stage, Environment and Age-dependent Demography of Plants' and 'Towards more realistic predictions of the effects of climate and land use changes on species distributions.' His current active project 'Using Spekboom to aid in a just energy transition for disadvantaged communities in South Africa' demonstrates applied research with social relevance.

Dahlgren collaborates extensively with researchers across institutions and countries, with particular strength in demographic analysis of plant populations. His work bridges fundamental ecological research with conservation applications, contributing to both theoretical understanding and practical conservation strategies for plant species.
