Lessons from plants

Our fellow Dr Luiza Teixeira has been doing inspiring work with plant specimens. In this piece, she links her work with some reflections on climate change, colonialism, and scientific knowledge.

Recent years have witnessed a revolution in museums. Many researchers and visitors alike now consider museum collections as something dynamic and diverse. As both a frequent museum visitor, and a researcher working with hundreds of plant specimens, I am very excited about the wide range of possibilities this collection revolution brings.

The study of specimens held in museums is fundamental for a better understanding of and planning for the effects of climate change. My special focus is on plant biology. Therefore, I am often visiting herbaria, which are special museums that hold plant specimens collected at different places and times.

In my research as a postdoctoral fellow at the VUB, I collaborate with the herbarium at Meise Botanic Garden. In this collaboration, I analyze and gather data from specimens of the plant Viscum album, commonly known as the European mistletoe. The idea is to investigate the effects of climate change in the ecology and physiology of this species, which is of great importance to natural and urban environments.

To complement my investigation, I often visit other herbaria. A few weeks ago, I had the opportunity to visit two of the largest herbarium collections in the world: the one at the Natural History Museum and the one at Kew Gardens, both in London. During this visit, I was able to analyze rare specimens and interact with colleagues. I also participated in a seminar held by the Linnean Society about trees and culture, during which the interactions among plants and people were discussed in a broad way.

These discussions, combined with a critical analysis of museums and their collections, including herbaria, are also fundamental to reckon with legacies of imperialistic practices. This way, we can reframe and discuss topics such as colonialism, indigenous knowledge, and representation in building scientific knowledge!

Dr. Luiza Teixeira-Costa is a postdoctoral fellow at the Biology Department of the Vrije Universiteit Brussels funded by a Marie Skłodowska-Curie (MSCA-Impact Co-fund) fellowship. She in interested in the multiple impacts of global change in the ecology of plants, with a particular focus on species that are endangered and/or act as key ecosystem components. In her work, Luiza combines a passion for museums and natural history collections with her curiosity about how plants function and interact with other species.
