The Toronto Entomologists' Association is holding its annual Student Symposium on March 28, 2026 1pm!

Graduate students, senior undergraduates and postdoctoral fellows are eligible to present a talk and apply for the Glenn Richardson Award.

Visit www.ontarioinsects.org/symposium/ for more info!

Presenting my poster right now @britishecologicalsociety.org ! 🌼🐝

I’m delighted to be featured as one of the student stories in the new Food from Thought Report: Cultivating Biodiversity and Ecosystems 🌱 (see page 19).

Also published today is a piece summarizing part of my MSc and PhD work.

Curious about the work? Learn more below:

Check out the latest publication from my MSc research with @nigeleraine.bsky.social where we surveyed bee and plant communities in rare TGP and savanna habitat and looked at what factors may contribute to their success 🔥🌼

Great PhD opportunity with an excellent supervisor:

Quantify traits of tree species across the western US to determine how tree populations and forest communities will respond to drought and fire.

For those not coming to the #ESCJAM in Calgary, if you like the look of these bags (laptop sleeve, pencil/dissection tools cases, etc.), I would be happy to make you a custom one (any size/your favourite bugs) in exchange for a donation to the @canentomologist.bsky.social student scholarsip fund!

Hot tip for @canentomologist.bsky.social members arriving in Calgary today:

The conference hotel has an airport shuttle (for $5) that runs on the half hour, but you have to call to book a spot.

Come work with us! My lab is looking for PhD student(s) to study elevational range shifts among dragonflies in Colorado. Reviewing applications now - apply by Nov 1 at the latest

You could spend your summers here!

While at The Arboretum, @uofguelph.bsky.social, I came across this beautiful moth caterpillar of _Hyalophora cecropia_ (Saturniidae). Enjoy!

With Upgraded Transmitters, We Can Now Track Migrating Monarchs Better than Ever Xerces has been helping to test these new tags for over a year, and we are excited to finally put them into widespread use.

Previous monarch tags could only be detected by specialized receivers, but this new version uses Bluetooth just like Apple AirTags, giving us a much better picture of the route each monarch takes on its journey! Learn how you can follow along with their migration ⤵️

Gold-covered hairballs may reveal why cats eat grass Spiky projections on plant matter may act like “drain snakes,” helping felines dislodge wads of fur

Why do cats insist on eating grass, when it only seems to make them throw up? Scientists have proposed many theories over the years, but the latest may be the one that sticks—literally. https://scim.ag/4ntn8VB

Showy dragonflies are being driven extinct by warming and wildfire Nature Climate Change - The authors use 1,603 estimates of local extinctions from 1980 to 2021 to show that dragonfly species with wing ornamentation have disproportionately gone extinct and lost...

new paper from my lab @cudenverclas.bsky.social in @natclimate.nature.com, led by @sarahnalley.bsky.social!

Dragonflies with dark mating ornaments on their wings are disappearing from parts of the United States that have had more warming and wildfire over the last 40 years 🧪🌍🐙

Climate Change Can Exacerbate Ant Invasion Impacts by Unleashing Indoor Populations Into Outdoor Environments Aim Thousands of non-native species have established populations and spread in outdoor environments (i.e., Naturalised), yet some populations or species only occur indoors, potentially due to unsuit...

Invasive ants that first colonise indoor environments are likely to be primed for rapid range expansion with climate change. Very interesting insight from Tsang et al. 🌐🧪🌏

Trait‐based island biogeography as a tool for studying future ecological communities Understanding the future of ecological communities under global change is among the most pressing challenges in plant ecology. Islands, with their reduced species diversity and clear boundaries, have...

Thrilled to see my Tansley insight review published in @newphyt.bsky.social!

I provide an overview of recent advances in integrating plant traits into island ecology and highlight key opportunities for future research in island systems.

Urban Wilderness: New Genus of Flea Beetle Discovered in Bustling City Parks A newly discovered genus of flea beetle is found only in mossy areas of parks in Shenzen, China, a metropolis of 20 million people.

A newly discovered genus of flea beetle is found only in mossy areas of parks in Shenzhen, China, a metropolis of 20 million people. Researchers say such urban species are a conservation paradox, dependent on conditions in an environment that also makes them vulnerable.

Species and trait abundance distributions as tools for understanding disturbance effects and community assembly in applied ecology Further insight into the links between disturbance and species abundance may come from the recognition that the species abundance distribution (SAD) is a special case of a broader concept, the trait ...

The abundance of male Bombus bimaculatus is providing a lot of opportunities for crab spiders in our garden. It is only in the last decade we have found this #bumblebee species in SK and it is spreading quickly, now as far north as Nipawin, and now maybe our most common in the south. #beesofcanada

In 2025 no-one should be publishing lists of ecologists whose work is essential reading but that contains only male names. I'm not sharing the article because it doesn't need the attention but please can we stop doing this.

Hey! If you haven’t already, you should connect with ESO @entsocontario.bsky.social to share your request on socials/newsletter!

Screenshot of the class showing me helping to work up a hammerhead shark

I am teaching an online shark biology and ecology class, which you can take for graduate course credit, CPE credit, or just for fun!

It includes an optional 3-day field research experience in Miami (November 20-22).

The class won't fill up but the field experience is half full- join ASAP!

The Centre for Biodiversity Genomics (CBG) is seeking ten taxonomic specialists in Collembola or any of the following insect orders - Blattodea, Ephemeroptera, Hemiptera, Hymenoptera, Lepidoptera, Orthoptera, Trichoptera!
