The final research chapter of my PhD is published! 🥳🥳🥳🥳 It shows how the ability of spider venom to paralyse prey scales isometrically with its ability to cause prey mortality! It is published with open access in Toxicon: X. You can check it out via the following link - doi.org/10.1016/j.to....

New paper led by @keithlnotions.bsky.social showing that the ability of a venom to paralysis prey scales isometrically with its ability to kill prey in spiders www.sciencedirect.com/science/arti...
Paralysis efficiency (PD50) scales linearly with lethality (LD50) in spider venoms
Historically, venom potencies have been assessed using measures of lethality, such as the median lethal dose (LD50). However, venoms may be selected p…

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.

Spider venom potency exhibits phylogenetic prey specificity but does not trade-off with body size or silk use in prey capture | Biology Letters
Spiders employ a diverse range of predator traits, including potent venoms, complex silk-hunting strategies and mechanical strength coupled with larger body sizes to capture prey. This trait diversity, along with the quantifiable nature of venom potency, ...

Dr Keith Lyons@keithlnotions.bsky.social · last yr.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!
