1/🧵My first preprint!🐛🌡️

We examine how environmental effects experienced during one life-history stage persist and modulate environmental responses in later life-history stages.

My second DPhil paper is out! A nice example of how continuous long-term monitoring of natural populations can be so valuable for understanding impacts of climate change on wild animals 🪶

Great pre-print led by @davididiaquez.bsky.social discussing possible causes of declines in adult and nestling mass. I suggested it be titled "Weapons of mass reduction"

Decline in body mass in adult (left) and nestling great tits. In the nestling plot, the purple line represents all nestling and the green line those that recruited to the population as breeders. Their different slope suggest an increase in the strength of selection on nestling mass something confirmed in the MS by analysing the temporal trends in selection differentials (see link for further information)

New preprint! 🐥🦠🏝️

We study a great speciator, the silvereye, to test whether parasites follow island biogeography rules, and find that parasite diversity and isolation effects depend strongly on transmission strategy.
