This picture is such an accurate representation of me trying to make sense of my own research.

Thanks for hosting me @uq-cbcs.bsky.social, I had a blast!
A big thank you to QUT PhD candidate Sarah Vollert for presenting at our seminar yesterday.

Stoked to have a cover photo for @ecography.bsky.social! In our paper doi.org/10.1111/ecog... we included temporal dynamics into SSFs, resulting in daily patterns of movement and habitat selection.
Simulating gave us dynamic spatial predictions across the landscape.

Really interesting talk by @taces.bsky.social on how we should be selecting protected areas knowing that our environment is changing #anziam2025

Disclosure: I love any talk with penguin pics 🐧

Thanks @matthholden.bsky.social! The good thing about being the first talk of a conference is that everyone thinks it’s the best talk so far #anziam2025
In a great talk @sarahvollert.bsky.social shows us how to use approximate Bayesian computation to calibrate and fit models when there is limited or no raw data and expert elicitation #anziam2025

Math enviro conferences are wild because one minute you’ll chat with someone about how Nemo comically misrepresented the East Australian Current, and the next you’re learning that hot showers are killing the planet (hot water systems make up 10% of Australia’s energy consumption!)

Our new paper shows that generalised ecosystem population models are tragically bad at predicting conservation outcomes: onlinelibrary.wiley.com/doi/abs/10.1... @cailanjs.bsky.social

Did we miss something? Is this impossible to predict? What does this mean for conservation planning?
Calibrated Ecosystem Models Cannot Predict the Consequences of Conservation Management Decisions
This study evaluates ecosystem models calibrated to time series data from experimental microcosms. Although multiple parameter sets fit the data well, the models fail to predict future dynamics, resp...

In true academic style, I'm finishing my new years resolutions just before due date.

The ideas behind this paper have been my passion project since day 1 of my PhD, and I'm pleased to announce that it's finally published!
