The European spiny water flea has reduced the diversity of native zooplankton by over 50%. A study finds it had been present in Canada for at least a century before first reports in the 1980s—and it may not have been introduced by humans. In PNAS: https://ow.ly/lkRK50ZV1nw
Thanks @cbcradiocanada.bsky.social for having us on to discuss our latest work @pnas.org (www.pnas.org/doi/10.1073/...)

Very proud of our newest paper now @pnas.org led by @danai-kontou.bsky.social @camplantsci.bsky.social with @laurentianu.bsky.social @isotopesuk.bsky.social Queens U. It's perhaps one of the most genuine "discoveries" we've ever made 🔬 Read it for free 👉 doi.org/10.1073/pnas... 🧵
Here is an intriguing ecological detective story involving several captivating characters, including invasive predatory fishes (catfish & basses) + an endangered native species, in the context of flow barriers & high turbidity. Some complex community ecology teased apart by Dr. Kontou & colleagues.
Excited to share the latest paper from my PhD covered in @uk.theconversation.com for anyone wanting a quick and easy read discussing the significance of our findings!
The original paper is also free to read at @pnas.org : www.pnas.org/doi/10.1073/...
Thank you so much!
Again, a study that was possible thanks to more amazing colleagues across the world who trusted me to play with their data and learn so much along the way 🐠🩵
In a rare source-to-sea study of one of South Africa's major rivers, we demonstrate how catfish predation, water turbidity associated with carp densities and flow barriers, shape freshwater fish diversity along the river. We show how these factors combine to suppress the impact of invasive bass!
Paper #2 is the first publication from my current postdoc @universityofleeds.bsky.social with @josiesouth.bsky.social also available open access @biolinvasions.bsky.social :

This study was possible thanks to the support and dedication of my amazing co-authors from @trentuniversity.bsky.social, @laurentianu.bsky.social, @isotopesuk.bsky.social as well as @Queen's University 🩵
It is a great example showcasing the complexities of establishing timelines of species invasions and the role of global climate change in facilitating rapid population growth and high impact of damaging aquatic species.
In a bit of a "plot twist" we provide evidence that the #spiny #waterflea, one of North America's most notorious invasive species has actually been around for at least a century before its first detection in Lake Ontario in 1982! This was the most surprising and significant finding of my PhD.
Paper #1 is my favourite chapter from my PhD thesis with @ecochangegroup.bsky.social @peterhousecam.bsky.social @camplantsci.bsky.social published open access in @pnas.org:
