Evolutionary ecologist, doing a PhD on phylogenetics and evolution of sex-determination in the Hawaiian Wikstroemia genus of flowering plants 🌿 At Lund University, Sweden. Ever disappointed in the non-existence of dragons 🐉🐉🐉 He/him/they/them ~ 🏳️🌈🏳️⚧️
Good article, but the framing is wrong. There is not a dearth of interest in taxonomy. There is a scarcity of funding and positions, which is a deliberate choice by funding agencies and institutions. The youth love taxonomy! It's the olds that are failing to meet their passion!
A new study from Anthropic finds that gains in coding efficiency when relying on AI assistance did did not meet statistical significance; AI use noticeably degraded programmers’ understanding of what they were doing. Incredible.
The Department of Ecology, Environment and Plant Sciences at @stockholm-uni.bsky.social has two open PhD positions, help us spread the word! 📣
We are looking for a PhD student in Lichen Biology, and one in Ecology & Evolution. Find more information and apply by 1 February below!

"Quick and easy" roadmap to finished paper. If I do two things per week I'll be done in no time... It's fine if I don't do anything else the coming three months, right?
One of my concerns with AI-assisted research in biology is that we're already looking only in the lamplight and AI incentivizes us to narrow the beam. Seems like it's happening...

My co-conspirator and fellow PhD student Lila writes for The Conversation about how plants have separate sexes, sometimes. Ever wondered something about plant sexual systems? How to start learning about it? I'd say start with this.
Folks, this can compromise the confidentiality of the review process, as well as authors’ intellectual property rights. Doing it is a breach of peer review ethics.
"Phylophytobiogeography" I type. I hesitate... is there no way I can be a bit more... specific?

![Handwritten poem by J Fraser, titled ‘The Corn Poppy’ with a sentence crossed out then four stanzas reading:
“The scarlet poppy reddens daily, Amongst the cornfields blossoms gaily, Makes comely neighbours wanton palely, and dazzles all beneath the skies, But beckons me with swanting [sic] eyes.
Uh! Could I like the gliding swallow, Explore the vale and upland follows, No more in smoky dens I’d swallow, No longer breathe the air that falls Midst crowded streets and staring walls.
Then would I bid adieu to collow, And scour the…height and hollow, Un…the downs and blithely follow, along the fields where bright corn rose – The glorious flaming poppy – glows.
To-day would have no room for sorrow, No boding thoughts to gloom to-morrow, And each day after fair would borrow Another glide along the plain, to search amongst the bended grain’”](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:6h2nzrepsboow5qu42xtebgn/bafkreig675ogx354npeaj4qewlpu4trssdkkdzlshvqieumvfs4juji3w4)
Botanist or poet? For National Poetry Day, we discovered poetry hidden amongst the personal papers of botanists - from J. Fraser’s 1919 poem on poppies to H.M Ward’s critique’s on his mother’s poetry!

If that sounds appealing, or if you simply hope to see more pictures from Hawai'i: stick around. There will be more of all this later ~ 🌿
I am also constructing a phylogeny of the wider Wikstroemia genus, hoping to 1. Determine the within genus relationships of the clades, 2. Assess the validity of the many widespread and overlapping, seemingly cryptic species, and 3. Biogeographically analyse how the Wikstroemia dispersed to Hawai'i.
My job is to suss out how the Hawai'ian Wikstroemia species are related, how they spread across the islands, what their population structure is like across various habitats, and how the gene trees of the sex-determining regions line up with the evolutionary history of the taxa we recognise today.
We investigate these emergent sexual systems through field sampling, greenhouse crosses, hybridisation trials, GWAS, and various other genomic methods for identifying sex chromosomes. However, we also use phylogenetics, biogeographic analyses, and population genetics. This is where I come in.
Since the Wikstroemia colonised Hawai'i less than 10 mya, several lineages have (seemingly independently) made the transition from ancestral hermaphroditism to dioecy. This makes these plants a perfect system for study of recent evolution of sex – a subject we still know surprisingly little about.
In Hawai'i we find a dozen endemic species of the Wikstroemia genus of flowering plants. Traditionally, native Hawaiians used the tough bark to make cordage, the red berries to decorate lei, and the pulped flesh to make a fish-stunning toxin to be dropped into tide pools.
Hello all new followers! Writing "Hi, I'm Ruben" feels redundant and uninteresting given that it says so on my profile already.
To introduce myself, I will instead introduce my study system and project. And to do this, I will post 16 images from 16 days of Hawai'i island fieldwork.

re: generative AI
I have finally fully and accurately explained my problem with how it’s marketed and used.
And now, you can use it, too.
And of course... sometimes you get to have a volcano in the background.
If I wasn't already tied up with a different plant, I'm not sure I could resist falling headfirst in love with the ʻōhiʻa lehua. Not only do they pop up out of the lava rock like it's nothing, they also have such amazing blossoms!
Don't look at the view, look at these plants! 🌿
You looked at them? You sure? Fine. Now you can look at the view. ⛰️
