A prediction of the preferred environmental habitat for the range-shifting yellowtail kingfish (Seriola lalandi) for March 2008, based on a combination of preferences for sea surface temperature, current speed and sea surface height.
Curtis Champion is a PhD candidate at the Institute for Marine and Antarctic Studies – University of Tasmania. He stopped by the Fish Thinkers blog to give us a run down on some of the research he is working on.
Species on the move and a quick explainer about how range-shifts are commonly identified
Climate. Change. No doubt you’ve heard of the phenomenon. And while a small number of our political reps sporadically break into the headlines for criticising its reality, the global scientific community has been busy forging novel territory to understand its ecological consequences. This emergent field is most-commonly referred to as “species redistribution science” because plants and animals shifting where they live (generally towards the poles or up mountains) in response to changes in temperature is perhaps the most perceptible ecological effect of climate change.

If you do not have subscription access to academic journals through an institution then to access a large proportion of academic journals you will be charged a fee for each paper; fees of $30 or more per article are common. And if you need to access a lot of papers then the cost quickly adds up. Needless to say many people don’t have the means to pay. Of course you could stick to open access journals i.e. free to read and download (Head to the directory of Open Access Journals for easy access to a whole range of open access journals), but by doing so you will miss a lot of what’s happening in the academic world*.
If you can’t afford to pay then you have a few options to get around the paywalls.
If you are in Jervis Bay and see someone knee deep surrounded by rays or alternatively sitting staring at rays for hours on end then chances are you are looking at the “mother of rays” otherwise known as Joni – the driving force behind the Stingray Diaries. She’s studying smooth stingrays throughout the Jervis Bay Marine park, in conjunction with Fisheries NSW and gives us a rundown on her research in her guest blog below…
Top shelf bottom feeders
Learning to swim by getting thrown off the end of a busy public wharf on the Hawkesbury River in nothing but a pair of hot pink floaties… Living in a swimsuit and covered in sand every single day of the year… Chucking tantrums when told to come inside after playing on the beach all day because it was dark… At the age of 4, saying with great certainty, “Mum, when I grow up I’m going to be a Marine Biologist.” Continue reading →
Damien Vella is Senior Horticulturist at the Botanic Gardens and does a great job of sharing natural history moments he encounters throughout his life on his instagram account. He has a particular skill for taking events from the backyard and telling a story that weaves in the underlying ecology in a fascinating way. He also shares one of my deep interests-that is creating habitat in backyards (Even better that it is the aquatic type).
Why would you study pretty fish on coral reefs if you could be trying to find grumpy weirdos like this Painted frogfish (Antennarius pictus)
Maarten De Brauwer is a marine biologist, dive instructor, biology teacher, PhD-candidate at Curtin University in Perth (Western Australia) and studies fish on soft sediments is lucky enough to work on sandy habitats ;). He also does a really nice job on the science communication front over at Critter Research! Below is his guest blog with some recent musings…
Thinking about sand and the fish (and researchers) that call it home
When I was asked to write a guest blog I first considered writing about fluorescent frogfish or about how weird fish that live on the sand can send children to school in developing countries. While I might do that another time, instead I decided to start a guest blog for Fish Thinkers by thinking about fish. Maybe because thinking about fish is what I am currently paid to do, though the fact that I’ve gone through 3 gin tonics and a fair amount of wine on a long-haul flight might play a role too.

A large part of my PhD involves working with researchers from NSW DPI and UOW to try and understand the movement patterns of fishes found on marine sands. And our recent paper (open access and free to read here) on blue-spotted flathead is the first piece of the movement puzzle Continue reading →
Who says sharks aren’t cute? Watch this video and tell me otherwise! And worth a quick blog post surely?
I recently spent a few days running a shark tracking workshop @tarongazoo projectshark in Jervis Bay with @400knots & @kye.adams. There were various other workshops running too – Including Matts on marinedebris and another on Port Jackson shark ecology and behaviour by Sherrie and Cat from Maquarie Uni together with Sue from crest diving.
After the event I got a chance to race off and film these little sharks getting released back into the wild by Conner who had just arrived from Macquarie Uni Fish Lab. Research from the lab has shown that when these PJs are adults they will migrate to Tasmania and back again each year! And often return to exactly the same crevice to breed each time!!
