What is the effect of substrate moisture content on sea turtle hatchling development? Bill Matthews @chris_r_gatto @LetsGetPhysEcol found hatchlings from high-moisture clutches produced less mean
swim thrust and spent less time powerstroking. https://t.co/QaQGCHahoK

'Eye in the sky: Using drones to spot and sex turtles'
1/7
Finding turtles at sea is hard but we need to count males and females to work out sex ratios. We compared surveys done by boat and by drone at Heron Island to see how sex ratios changed during the season

[Richard Reina @LetsGetPhysEcol]

6/7
Our results show:
1. sex ratios need to be measured throughout the breeding season
2. drones are better than boats for surveying in many situations
3. the sex ratio shifts from male-biased to female-biased
4. drones are really cool

The drone also has the advantage that it can survey in areas like the reef crest, which are unsafe or inaccessible for boats.

[Richard Reina @LetsGetPhysEcol]

4/7
We saw more turtles per minute when surveying with the drone than with the boat and the drone had the advantage of not disturbing turtles and causing them to dive. We consider using the drone to be a much less invasive technique that gives a more accurate survey result.

@TabbyTabs24 Yes, I imagine that unless the water surface is completely still you will get a lot of image distortion

[Richard Reina @LetsGetPhysEcol]

@TabbyTabs24 Cool thanks. Do you think it would work if you were above the water in a boat or does the camera need to be submerged?

[Richard Reina @LetsGetPhysEcol]

@TabbyTabs24 Thanks Tabitha, what's the maximum workable distance away from the turtle and how important is water clarity?

A method for the collection of early-stage #seaturtle #embryos
Embryos are very small when eggs are laid, making them hard to locate and study. Little is understood of important molecular processes, like embryonic arrest and mortality, occurring at this stage 1/6

New research led by @MonashBiol's Professor Richard Reina has found drones to be an effective alternative to boats in the search to find and identify the sex of green turtles on the Great Barrier Reef.
