"As the oceans warm, many marine species are on the move to keep pace with their preferred environmental conditions – and it’s having a profound effect on the structure and function of the ecosystems they leave behind and those they move into. ..."

We know many #marine #species are #redistributing around #Australia, but with the scale of the continent, there are many regions we have no information about.
New #openaccess research: doi.org/10.1111/gcb.15634
Nearly 200 Australian #marine species are known to be on the move b/c of climate change, but this is only the "tip of the iceberg".
Fantastic press release by @IMASUTAS on our new paper. shorturl.at/afzDL @GrettaPecl @curt_champ

Hot off the press: A continental scale review of range shifts in Australian marine systems finds 198 species on the move since 2003, with 87% of redistributions occurring in a poleward direction! #SpeciesOnTheMove

Baby long-necked #turtles stole the show last week while helping @TiffanyJNay survey #freshwater fish.

Tropical fishes extend ranges into temperate zones during heatwaves.
New study shows the distance extended depends largely on whether habitat generalists or specialists.

Juvenile #sharks are heavily predated - what anti-predator strategies are they using? Check out the new research here: doi.org/10.1016/j.anbehav.20…
Juvenile PJs #sharks prefer to freeze in the face of predation (☠️Necromones☠️) but if detected initiate 'fight/flight'. Regardless of strategy, predation effects persist (3h after).
3rd PhD study published! @CulumBrown doi.org/10.1016/j.anbehav.20…

Excited to share new paper lead by amazing student, I. Silva Romero, w @JohnFBruno and @maggybrandt.

Looks like tropical vagrant fishes cause some crowding that pushes them and residents to less preferred habitats. Nice use of 3D mapping to address a range expansion question Tom Taylor. @USydMSI @Sydney_Science @SydneySOLES

#Sharks in #eggs show diminished antipredator responses over time to non-predatory cues, indicating a capacity for early #learning and #cognition. publish.csiro.au/MF/MF20108
PJ #Shark embryos can differentiate between #predator smells, and show different #antipredator responses. But it depends on how old they are. (publish.csiro.au/MF/MF20108)

#babyskates close up showing blood flow through the gill filaments. Clip on macro lens. Might have to move to a real camera.

Odd happening. Local woman called and said a piece of seaweed that had tried in the back of her truck turned out to have little sea creatures in it. Big-eyed Skate egg case torn open. Embryos in the garage for 5 days. Now in my lab. Hope they make it.
