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...
sciencedirect.com
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…

Big W for habitat management and spider fans! Rediscovering such a cool UK spider after 40 years of absence on the Isle of Wight! Well done @graemelyons.bsky.social and Mark! #spider #IsleofWight #rediscovery t.co/FSD1nv2ina

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, ...

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!

Are you looking for a distraction? Do you love natural history and museum specimens? Join @joshlukedavis.com and I for "The 'Perfect' Specimen" - an irreverent look at the natural world through via some of the @nhm-london.bsky.social's 80 million specimens, and increasingly random adjectives...
Blurred background is a colour photograph of two people (on the left one in checked red/blue/white shirt and glasses, on the right one in blue shirt with blue glasses) looking at specimens in jars on shelves. In the foreground in focus is a large old fashioned looking specimen jar with an unidentifiable specimen within it. Over this the title of the podcast 'The "Perfect" Specimen is written in white text. In the top left hand corner the Natural History Museum logo appears in white.
