I wooden dream of having a post full of wood puns. On the other hand my alder ego often gets the best of me and I may have to cherry pick a few. I am participating in the new round of SciFund Challenge. I am hoping yew (I can’t help myself) will help me support some research on wood falls. Details will be coming soon about how you can contribute! Fir now I have link roundup with my and my collaborator’s recent posts on this cool research.
Not to board you with more but below is a gallery of images that I think will spruce up the post. The photos are from wood falls nearly two miles deep on the Pacific seafloor and many are courtesy of the Monterey Bay Aquarium Research Institute. I hope I left you pining for more.
My collaborators Jim Barry and Chris Lovera inspect a collection bag for the wood falls
The siphon of wood boring bivalve Xylopyolas sp. notable because of the protective plates at the end
A species of minute snail (<3mm) found on the wood falls
Xylophaga concava, a species of wood boring bivalve. With a shell unlike other clams the siphon is also much larger than the shell
The elegant damage done by wood-boring bivalves on a log
The benthic elevator sets on the back deck of the Western Flyer as we depart from Moss Landing
Here I am shiving wood for science
The golden setae (hairs) of this worm make it one of the more charismatic invertebrates from the wood falls
Me carefully picking invertebrates out of bored log
My favorite snail from the wood falls because of its milky white color
Kurt Buck looks over my work as pick invertebrates from the log.
The ROV Doc Ricketts being deployed through a moon pool on the Western Flyer like a bond villian
The remains of log that spent 7 years on the deep-sea floor
More Bond like robots and moon pools
This worm is the craziest looking organism that occurs on the wood falls
Elephant trunk? Nope. Siphon from a wood-boring bivalve
Tiny hydroids take up residence on the polypropylene rope on the wood fall
A grayish colored halo forms around wood falls. This represents an area of immense bacterial action feeding off wood bits and feces coming out of the wood fall.
Sea cucumbers, Amperima, stretch out their tentacles to feed in the sediment nearby
The foreboding last minute before I collect this squat lobster with the suction sampler
Even through the mesh it is clear to see that the log has been bored.
Benthic elevator on the bottom holding the collection bags with the wood falls in them.
The urchin Tromikosoma. Note the awesome club spines
Another bored wood fall
A scale worm crawls on the outside of the wood fall
MOAR SEA PIG!!!
EVEN MOAR SEA PIG!
Several squat lobsters remain after a wood fall is collected
Sea cucumbers, Amperima, and Xenophyophores, a large unicellular organism, dot the seafloor near the wood falls
A fluffy mound of wood-boring bivalve feces (orange specks), wood bits, and bacteria. A feeding white snail finds this an enjoyable snack.
A fish with a fungal infection swims over one of the wood falls
A squat lobster covered in bacteria and sediment tries to hide
A squat lobster stands gaurd
ROV collecting sediment cores
Now time to grab the wood fall
A squat lobster feeding on a wood fall
This squat lobster does not seem amused

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, created to facilitate research to address fundamental questions in evolutionary science. He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards. Craig’s popular writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.
