Hey! Got a bunch of new followers, so time for an intro!

I'm a PhD student studying the multilevel society of the Superb fairy-wren. Passionate about all things birds, ecology and behaviour!

Stay tuned for science content and fieldwork stories!

Without forward-looking models, biodiversity policy risks missing the road to recovery.
Our new PNAS article calls for predictive tools and a World Biodiversity Research Programme to guide global action.

The secret to shrew brain shrinkage? 🤔
Not cell loss, but water loss!

Light pollution is causing birds around the world to sing for longer each day, prolonging their vocalizations on average by 50 minutes, according to a new study in Science.

Learn more: https://scim.ag/3Uz7vzP

A figure showing that light pollution prolongs avian vocal activity by nearly an hour. (A) Most diurnal bird species show bimodal vocalization patterns with peaks in the morning and evening; in light-polluted landscapes (yellow shading), the first vocalizations occur earlier in the morning and the last vocalizations occur later in the evening. (B) Globally—averaged across species, space, and season—onset of morning vocalization shifted 18 min earlier in the brightest landscapes versus the darkest landscapes. (C) Similarly, evening cessation was delayed by an average of 32 min. In (B) and (C), lines are means and shaded regions are 95% confidence intervals (CI) of model predictions.

I wrote (ranted) on experimental design as I was frustrated as an editor at how little guidance students were getting. I underestimated the interest in the issue: it has been downloaded 10,000+ times! Clearly it’s something we need to be talking about more. onlinelibrary.wiley.com/doi/full/10....

Principles of experimental design for ecology and evolution

Here I argue that we do not discuss experimental design, often until it is too late. This editorial seeks to begin a conversation about how and where to replicate appropriately.
