Meet Lucy Goodwin! Lucy is a PhD student at the University of Liverpool studying abyssal plain #FoodWebs at the Porcupine Abyssal Plain, and exploring how body size influences feeding roles in megafauna, and whether these patterns are temporally stable. Find her @deepsealucy.bsky.social!

"Hi, I'm Lucy and I'm currently a PhD student at the University of Liverpool in the UK. My research is focused on abyssal plain #FoodWebs, where I use the Porcupine Abyssal Plain (PAP) as my focus area."

"I am currently working to determine whether there is a relationship between body size and feeding niche of abyssal megafauna, using stable isotope analyses, and ultimately identifying whether the functional roles of organisms in this habitat is dependant on body size."

(Image: Lucy standing in front of her poster “Abyssal body size-trophic niche relationships vary in response to food flux”.)

"This work is conducted on animals collected during cruises to the PAP, including many sea cucumbers such as the recently redescribed Psychropotes buglossa, and gorgeous squat lobsters, all of which make up the NOC Discovery collections. "

"My stable isotope analyses are done in-house at the University of Liverpool LIFER lab, and I presented the results on Thursday at 10am (Hong Kong time)."

SCALE WORM ASSOCIATIONS in sea stars are close! The worms, Arctonoe sp. remain attached even after the stars have died. This is a slime star, Pteraster sp., the worm lives in the tube foot groove. Will need to see if this is a known association.. #echinoday #wormwednesday

Lucy Goodwin have found that large animals normally occupy higher trophic levels as they can consume larger food items. But does it hold up in the abyss?

Really enjoyed giving my talk today on abyssal food webs and body size 🏵️ A recording will be available soon and work is to be published, still please shoot any questions my way! I'll be at #17DSBS until the end, and here on bluesky at any time 💙 Huge thanks @dsbsoc.bsky.social

Using my first bluesky tweet (bleet?) to share a sneak peak of my poster at #17DSBS, I'll be there from 5:30-6:15pm ready to answer any questions! @dsbsoc.bsky.social
