Thomas Flower (PhD, University of Cambridge, 2012) is a biologist whose work focuses on evolution, ecology and conservation biology.

Flower's fascination with the natural world began with his early dinosaur obsession. However, after realizing dinosaurs were mostly extinct, he focused on their living descendants, the birds.

Following a childhood spent searching for rare raptors and other exciting organisms in the United Kingdom, Flower pursued his love of animals by undertaking a Bachelor of Science degree in Zoology at the University of Bristol.

He then headed to the Kalahari Desert in South Africa where he spent four years studying the incredible cooperative behaviour of meerkats. During this time, Flower managed an international research project and a 3500 Ha game reserve, helped with production of the hit TV natural history program Meerkat Mannor, and completed his Master of Science degree at the University of Pretoria on food competition in meerkats.

For his doctorate at the University of Cambridge, Flower returned to his primary love and studied the deceptive tricks of a bird, the fork-tailed drongo and their interactions with other animals, including meerkats. A summary of his work has conveniently been produced by the BBC and David Attenborough. He joined the University of Cape Town (UCT) in 2012 as a postdoctoral researcher to continue his studies on fork-tailed drongos, as well as a number of other birds throughout Southern Africa.

In 2015, Flower moved to British Columbia to join Simon Fraser University (SFU) as a Banting Postdoctoral Fellow, where he expanded his work to explore how understanding animal behaviour can inform biodiversity conservation. Specifically, he undertook research investigating how forestry in British Columbia affects predation of birds eggs and chicks by Stellers jays. Flower retains research associateship at both UCT and SFU, where he supervises students.

The delight Flower gained from working with and teaching students during his career compelled him to join Capilano University in 2017. Here he works to prepare the next generation for new challenges in the biological sciences and share his own fascination with the natural world through excellence in teaching.

I consider it a privilege to share my fascination with biology, from the incredible mechanisms governing genetics and biochemistry, through anatomy and physiology, onward to the evolution of whole organisms and their interactions with the environment.

In class, I share my experiences as a biologist and encourage students to perceive science as a process of exploration, to which they can contribute with meaningful discoveries. I support student success with class resources, activities and assessments that address specific course objectives, while also helping students develop their general academic skill set.

Whenever possible I take my students out into the natural environment to practice applying their knowledge in the real world.

I am an evolutionary ecologist interested in empirical research to further our understanding of biological systems, facilitate biodiversity conservation and equip the next generation with environmental stewardship skills.

There are two primary themes to my research: (i) how do interactions between species shape the evolution of animal behaviour, and (ii) what are the consequences of human-caused environment change for animal behaviour and biodiversity conservation.
