Biogeography of mutualistic plant-animal interactions in the Dalsgaard Group
The Dalsgaard Group study mutualistic plant-animal interactions across islands and macroecological scales, with the aim to understand how historical and ecological processes influence plant-animal interactions.
Island biogeography of mutualistic plant-animal interactions
Island biogeography has proven fruitful in developing theories on how geography - especially area and isolation - influences patterns of biodiversity. However, we have remarkable little knowledge on how island geography influences mutualistic plant-animal interactions. A project funded by the Independent Research Fund Denmark (DFF) will focus on the influence of island geography, climate, anthropogenic pressures, and species traits on mutualistic plant-pollinator and plant-frugivore interactions. The project will be conducted across various islands in the Caribbean. The project will commence in 2021 and includes Dr Christopher Kaiser-Bunbury and Dr Benno I. Simmons (University of Exeter, UK) and Dr Mauro Galetti (University of Miami, USA). We will be hiring one PhD student and one Postdoc to join the project.

Macroecology of mutualistic interactions
Using large databases of mutualistic plant-animal interaction networks. We are studying how mutualistic interactions vary across the macroecological scale, focusing on whether species traits or local abiotic and biotic conditions are the main determinants of plant-animal interactions. Notably, we ask how historical and ecological processes, such as historical climate and current climate, influence plant-animal interactions. Most work is focused on plant-hummingbird interactions, but work includes both pollination and frugivore systems.

Biogeography of crop pollination
Plant–pollinator interactions are altered by anthropogenic-induced global change, notably land-use and climate change. Using fieldwork data on pollination of crops, we ask how climate and land-use influence the pollination and fruit set of crops. The spatial scale ranges from the regional to the global scale and is based on own collected fieldwork data as well as on databases.
