I did a thing :D First chapter of my PhD out now! 🌱 (first paper ever 🥳) Traits are historically hypothesized to age synchronously, but it is no longer the case. We quantified asynchronous ageing in Seychelles warblers and reviewed potential reasons for why this may be.

Do all traits age together? A long-term study of wild Seychelles warblers shows ageing is surprisingly asynchronous, with some traits senescing while others remain unchanged. doi.org/10.1093/evle...

Gut Microbiome Communities Vary Across Translocated Populations of the Seychelles Warbler

Conservation translocations are an increasingly common tool used to help combat species extinction but their success is dependent on a wide range of abiotic and biotic factors. To date, the potential...

Broken families can have huge effects on children, even later in life. But is that the case in species other than humans? Read my latest article in the ‪@aunz.theconversation.com‬ on mate switching effects in offspring of the ‪@seychelleswarbler.bsky.social‬ 👇 theconversation.com/the-chicks-a...

Parental separation in humans can deeply affect children. But in another monogamous pair-bonding species, it has no such effect.

Our new paper, using shotgun metagenomics on the gut microbiome, shows small but interesting longitudinal changes with age in a natural population. 🧵1/5 academic.oup.com/ismecommun/a...

Metagenomic analyses of gut microbiome composition and function with age in a wild bird; little change, except increased transposase gene abundance

Abstract. Studies on wild animals, mostly undertaken using 16S metabarcoding, have yielded ambiguous evidence regarding changes in the gut microbiome (GM)

Then, we studied divorcing using long-term data of @seychelleswarbler.bsky.social addressing all these shortcomings, and found that divorce is related to male age, pair-bond tenure, and reproductive success, but that there are no strong fitness consequences to divorce

We addressed 5 shortcomings: (1) divorcees and widows and (2) initiators and victims of divorce are not disentangled, (3) consequences of divorce and widowhood are not studied together (4) long-term consequences and (5) age-dependency of divorce are not addressed

New paper: causes and short & long-term consequences of divorcing 💔. This papers highlights the shortcomings of studying divorce to date and provides methods to address them. Plus some new insights on divorcing in birds! See 👇 doi.org/10.1111/ele....

Causes and consequences of divorce in a long‐lived socially monogamous bird

In socially monogamous species, sexual selection involves both initial mate choice and mate switching. We found that divorce in Seychelles warblers occurs most among young and old males, and in pairs...

Why These Little Birds Divorce Despite The Risks

Ditching your partner doesn’t seem to work all that well for Seychelles warblers, even if they keep the house, which may be why not many do it.

The Seychelles warbler is a small passerine endemic to the Seychelles islands. The original remnant population of this rare bird has been studied on Cousin Island since 1981, with intensive monitoring since 1985.

We will post about research on the Seychelles warbler here. Research is conducted @unigroningen.bsky.social @sheffielduni.bsky.social @uniofeastanglia.bsky.social in collaboration with Nature Seychelles

Rainfall is associated with divorce in the socially monogamous Seychelles warbler

To the best of our knowledge, our study is the first to show that extreme rainfall increases the prevalence of divorce in a socially monogamous population. Our findings add to the growing literature ...
