Current research project

Carnivorous plants have captured the imagination and wonder of people all over the world, including scientists, naturalists, horticulturalists, and artists alike. Even Charles Darwin had a glasshouse full of carnivorous plants, which he thought were "the most wonderful plants in the world"! In this glasshouse, Darwin conducted a number of experiments, and was the first to provide scientific evidence of plants capturing and dissolving insect prey. This research is published in his treatise Insectivorous Plants, and has become the basis of more than a century of research on these amazing plants.

How carnivorous are carnivorous plants?

In my PhD research, I am using stable isotope techniques to figure out just how carnivorous these plants really are. In other words, how much do they rely on captured prey to get essential nutrients (like nitrogen) and how much do they get just from the soil? Most of my research has focused on carnivorous plants from my home-state of Western Australia, which hosts nearly a third of the world's carnivorous plant species! Across both the southwest biodiversity hot-spot and the northern Kimberley region, Western Australia is home to: 

  • A few hundred Drosera (sundew) species with sticky hairs

  • About 6 Byblis (rainbow plant) species also with sticky hairs

  • More than 60 Utricularia (bladderwort) species with suction traps

  • The rare aquatic Aldrovanda vesiculosa (waterwheel plant) with snap traps

  • The endemic Cephalotus follicularis (Albany pitcher plant) with pitfall traps

 

Conservation of carnivorous plants

Unfortunately, many carnivorous plants around the world are under threat from the loss and disturbance of their natural habitat and from illegal poaching of plants from the wild. Sir David Attenborough is a proud supporter of carnivorous plant conservation, as the Patron of the IUCN Carnivorous Plant Specialist Group. This group of experts recently undertook conservation assessments for a majority of the world's carnivorous plants, an important first step towards developing informed conservation and management plans for these species. Through my research, I hope to provide information that can help support this work.
