Hello friends! Between #ODotCOmm18 , #NEPacSharks18, #SFUPostdocResearch day, and ocean chess, I've been clogging your feed (and my own head) more than usual the last week and a half. I'm going to take a quick twitter break. Back this weekend. Be excellent to each other.

Home from a great #NEPacSharks18 !

That’s it for #NEPacSharks18 ! Great event. Thanks @SeattleAquarium !

#NEPacSharks18 Larson: The sixgill sharks that were here may have been part of a single cohort group- they left to go to the ocean to grow up after spending years here using this area as a nursery area

#NEPacSharks18 Larson: Observations of sixgill sharks in Seattle harbor have declined in the last 15 years, and haven’t been seen here in some time.

#NEPacSharks18 Larson: Most Seattle residents didn’t know there were big (5 meter) sharks right in the harbor! Divers and fishermen had long known they were here, though. Aquarium started studying in 2003

#NEPacSharks18 @lets_experiment : Experiment has funded 33 shark and ray research projects (including mine!)

#NEPacSharks18 @lets_experiment : Experiment has crowdfunded 773 science projects, raiding almost $8 million from over 40,000 backers?

#NEPacSharks18 @lets_experiment : Was told as an undergrad “the system doesn’t fund people like you!” (Young, and seeking a small amount of money)

Next at #NEPacSharks18 , @lets_experiment is going to talk to us about crowdfunding shark research!

I used their platform to raise over $8,000 for my PhD work, covering the lab fees of one project!

(I’m going to finish writing up that manuscript next week, I hope)

#NEPacSharks18 @jennybigman : Looked at whether respiratory surface area is related to metabolic rate, and whether this relationship is different for elasmobranchs than for other groups of fishes and other vertebrates

#NEPacSharks18 @jennybigman : Metabolic rate is related to body mass. Bigger critters need more energy, a relationship that usually scales to a slope of around 2/3

Next at #NEPacSharks18 is @jennybigman from @Sfu @E2ocean talking about comparative gill morphology

Just 7 talks left at #NEPacSharks18 ! It’s been a great meeting. Thanks for hosting us @SeattleAquarium !

#NEPacSharks18 @helenyaan : Uses GDP, Ocean health index, landings, and other variables to infer whether sawfish are likely to be found in a particular country where we don’t have enough data

#NEPacSharks18 @helenyaan : Sawfish have an elevated risk of extinction. Slow growing, long lived, few pups at a time, live in shallow coastal water near people, and the rostrum gets caught in nets.

#NEPacSharks18 @helenyaan : Sawfish’s rostra can be 1/3 of the length of their entire body. “My height, but pointy, and on a fish”

#NEPacSharks18 Aguirre: during anomalous temperature years, bat rays switch their diet almost completely to pelagic red crabs-which are abundant but have low caloric content.

#NEPacSharks18 Tamburin: Mako young of year and juveniles each have a distinct isotopic signature, suggesting change in diet as makos age. Juvenile mako and juvenile white sharks have similar isotopic signatures to one another, though.

#NEPacSharks18 Tamburin: Sharks are vulnerable as pups, and this part of their life is relatively poorly studied. Many species live in coastal nursery areas for the first year(s) of their life.

Good morning! I’m tweeting from the last morning of #NEPacSharks18 at @SeattleAquarium ! RT stories that interest you, and feel free to ask questions!

Buying beers for all my graduate student colleagues at #NEPacSharks18 and telling them about @rmacpherson ‘s pay it forward principle.

Join us tomorrow morning, there’s one more half day of #NEPacSharks18 sessions! Tomorrow: stable isotopes, biometrics, and reproduction

#NEPacSharks18 @Drsharkbrain : Bigger, faster sharks are likely to use more habitat than smaller, slower sharks. Also trophic level, prey size, and thermoregulation will affect habitat size

#NEPacSharks18 Reichert: about half of all chondrichthyans are deep sea (200-3,000m,) catsharks are the biggest group of these (~150 species)

#NEPacSharks18 @EmilyNMeese : horn sharks eat urchins, shrimp, squid, and small fish. They’re nocturnal hunters.

Next at #NEPacSharks18 @EmilyNMeese , talking about horn shark movement ecology
