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.

Daniel Swadling is a new PhD student at the University of Wollongong who is embarking on a project to better understand the relationship between temperate fishes and their habitats. He also loves his luderick and drummer fishing using an old school Alvey reel, so he is going to fit in just fine and I sense there will be plenty of fishing adventures in the future. Below is his guest post recapping his honours project and where he is heading with his PhD research.
My name is Daniel, I am a PhD student at the University of Wollongong (UOW) Continue reading →
The report will be used to determine the most important threats and risks to the NSW marine environment and your submission could help decide where management actions are directed. Note: submissions are due this Saturday the 30th of April.
The website contains the current threat and risk assessment for a range of human activities on environmental assets (for e.g. fish, beaches, rocky reef etc.). It is interesting to see what the current risk ratings are for certain human activities and how the NSW Marine Estate justify these ratings.
To search for this information the NSW Marine Estate has developed an interactive tool to help you navigate through the draft assessment. Once you have identified a human activity (for e.g. recreational fishing) and its risk on an environmental asset (for e.g. the fish assemblage) there are links to a variety of reports used to justify this ranking plus a link to provide your own feedback.
The interactive tool did take me some time to get the hang of, so below are instructions and screen grabs to help you navigate your way through the site.

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…

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).
