Word of the day is ‘swullocking’, from 19th-century East Anglian dialect: sultry, sweltering, and sudiferous (sweat-inducing).

#BiologyLetters Spiders use different traits to capture prey, including webs or fangs to restrain prey before delivering their paralytic venom. But is there a trade off between venom potency and body size or silk use in prey capture? royalsocietypublishing.org/doi/10.1098/... #ecology #evolution

Big thanks to all media outlets that have covered our recently published work on spider venom potency thus far! I have been blow away by the interest and support everyone has showed. Grateful to @drivetime.bsky.social @wlrfm.bsky.social and
Galway Bay FM for having me on their shows on Thursday.

As the US government slashes Harvard’s funding, Nature has learnt that researchers at the university have lost nearly 1,000 grants worth more than US$2.4 billion.

Absolutely fascinating stuff!!!!

Doi for our manuscript can be found in CASSYNI alongside our seminar, using the doi link above.

Along with our research on spider venom potency published in Biology Letters, we were kindly asked to prepare a seminar discussing the manuscript for @royalsocietypublishing.org/@cassyni.bsky.social's "Ecology and Evolution Seminar Series" doi.org/10.52843/cassyni.slp5xv. It's free to watch! Enjoy!

Finally, we tested how venom yield scaled with body size, finding allometric scaling close to 0.75, suggesting that metabolic costs are one of the main drivers of venom production, similar to what was found previously in snakes (onlinelibrary.wiley.com/doi/abs/10.1...).

We also tested for evolutionary trade-offs between venom potency, body size and silk use in prey capture but find no relationship between either size or silk use with venom potency which was unexpected and is both supported and contested by other studies in the literature.

By comparing over 70 species we show that spider venoms have evolved to be phylogenetically prey-specific by testing how venom potency changed when tested on animals closely related to a spiders diet compared to when tested on species more distantly related to their diet.

Our latest research on the factors influencing spider venom potency has been published in Biology Letters! doi.org/10.1098/rsbl... Big thank you to my supervisors Dr @healyke.bsky.social and Dr Michel Dugon
along with the media team @uniofgalway.bsky.social
for spreading the word!

Delighted to see our latest paper on the macroecology of spider venoms led by @keithlnotions.bsky.social published today in Biology letters. royalsocietypublishing.org/doi/epdf/10....
