How long does taxonomy take? Botanist Jessie Prebble can tell you

Taxonomic research involves a number of aspects, including field trips, lab work, studying and comparing live plants (in the field or glasshouse) or pressed specimens, and reading previous scientific papers. Not to mention analysing and interpreting the data, incorporating previously published research, and writing up the results for publication. Sometimes, such research forms the basis of a post-graduate thesis (Master’s or PhD).  Curator Botany Heidi Meudt talks about one student’s journey.

Jessie Prebble started her PhD research in 2012 when she went on one of her first forget-me-not field trips to Northland. She was co-supervised by Jen Tate and Vaughan Symonds (Massey University), and me.

During the course of her PhD (2012–2016), she was based here at Te Papa for about two years, where she was able to work very closely with the collections and Botany staff in our herbarium.

She finished her thesis in 2016 and is now a Botanist at Manaaki-Whenua – Landcare Research.

Taxonomy takes time

You might think the research ends when a student submits and defends their thesis, but the process does not stop there. The next step for scientific research is publication in a credible, peer-reviewed scientific journal.

The peer-review process usually means further revisions to the text, before it is finally accepted and published. For taxonomic research, in particular, this step is crucial as it provides “effective publication” for any new scientific names as well as a permanent record of the research.

Jessie published the final chapter of her PhD thesis in May 2022. It is the culmination of a decade of her comprehensive research on this group of tiny forget-me-nots, and includes the publication of her 2016 PhD thesis along with four peer-reviewed, scientific papers based on that thesis from 2015, 2018, 2019 and 2022. It is also a fantastic example of how Te Papa supports student research.

Congratulations, Jessie, on achieving this important milestone!
