Please share broadly: I am looking for a postdoctoral fellow to work on a collaborative project on the temporal population genomics of invasive Capeweed (using contemporary and herbarium genomics), with ‪‪@shaky-dingo.bsky.social‬ and colleagues

And this paper came about purely through collaboration with other grad students in the department which was super fun - so big shout out to Isaac Eckert, Olivia Rahn, @cameronso.bsky.social, and Rowan for helping us out

Using herbarium collections to study genetic responses to global change Earth's c. 406 million herbarium specimens represent a largely untapped resource of genetic data that could transform our understanding of global plant populations. Advances in DNA sequencing have ma...

What can #herbarium collections tell us about genetic responses to global change? A lot!! 🌿

Thanks Andrea!!

Thanks Dan! And glad to hear!

Thanks! This should include some adjunct, but they need to have an affiliation with a university at least

In case you missed my talk at #CSEE2025, you can explore your own collaborative networks and see a little summary on my website!

A little teaser of some collaborative network graphs

I’ll be at #CSEE2025 talking about patterns of collaboration in the Canadian eco/evo research community 🇨🇦

If you’re a eco/evo prof in Canada, odds are you were one of my data points… so come check it out! Wednesday - 4:30 - Science in action

Blitz the Gap 2025

One week until Blitz the Gap (www.blitzthegap.org) starts - a Canada-wide event to fill biodiversity data gaps with iNaturalist! @laura-pollock.bsky.social

I’ve been helping plan this meeting so I can guarantee it’s gonna be a fun one 🐟🐟🐟

Collective behavior diverges independently of the benthic-limnetic axis in stickleback - Behavioral Ecology and Sociobiology Comparing populations across replicate environments or habitat types can help us understand the role of ecology in evolutionary processes. If similar phenotypes are favored in similar environments, pa...

Are you interested in the genomic basis of repeated adaptation? The RepAdapt group now has >70 members working to re-run their whole genome shotgun datasets through a common SNP calling pipeline, sharing VCFs, and working together to analyse data. Please contact me if you'd like to contribute!

And please check out the Blitz the Gap website for more info on this initiative and how to get involved!

I helped design some of the *challenges* targeted at specific places, habitats, or species where we need more data

Rapid Neural DNA Methylation Responses to Predation Stress in Trinidadian Guppies DNA methylation (DNAm) is a well-studied epigenetic mechanism implicated in environmentally induced phenotypes and phenotypic plasticity. However, few studies investigate the timescale of DNAm shifts...

How fast can brains epigenetically respond to predation stress?

We found that brain DNA methylation in guppies can shift within 30 minutes of predator exposure — with different time courses between males and females.

So happy to finally see my undergrad thesis published, and a big thanks to Sigal Balshine and @bbolker.bsky.social for making it happen :)

Parental care drives the evolution of male reproductive accessory glands across ray-finned fishes Abstract. Reproductive accessory glands are organs involved in reproduction that do not directly produce or release gametes but can play crucial roles in s

Ever wondered why (some) fish have prostates? Find out now in @journal-evo.bsky.social ⬇️

Surprisingly, it has more to do with parental care and less to do with sperm competition 🐟 🧪

Excited to meet some new people and hear about cool research!
