As expected, the highly anticipated Blue Planet II series has been nothing short of amazing. This week we are incredibly lucky to have a guest post by shark researcher; Samantha Andrzejaczek who helped film the upcoming Blue Planet episode. Sammy is a PhD candidate at the Australian Institute of Marine Science and University of Western Australia investigating the vertical movement of sharks. She also runs a fantastic blog – www.sammyshark.wordpress.com, which we definitely recommend checking out. Read on to go behind the scenes of Blue Planet II. You can watch the episode this Saturday night (17th) on Channel 9 in Australia. Continue reading
Pregnant Sharks and Rays Abort Offspring When Fished – Guest post by Kye Adams
Have you ever seen a viral video of a shark or ray giving birth (e.g. River Monsters)? Unfortunately, it turns out these videos have a pretty dark explanation: There’s a fairly high chance the female is actually aborting her pups due to the stress of being caught. Continue reading
Following on from a previous fish thinkers guest post: “Close to home: what drives the distribution of intertidal rockpool fishes?”, University of Wollongong Researchers Kai Paijmans and Dr Marian Wong have published new research that offers novel insight into the secretive goings on of rockpool fish communities.
For those who aren’t inclined to wade through scientific literature, Below is an overview by lead author Kai for your enjoyment. Continue reading
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. Continue reading
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).
Below is his guest blog discussing backyard habitat ponds… Continue reading
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.
