Bigger is better when it comes to female fish and feeding the planet

A new paper led by Centre researchers Diego Barneche, Craig White and Dustin Marshall and published in the prestigious journal Science has confirmed what field biologists have long suggested: that larger mothers reproduced disproportionately much more than smaller ones. The findings clash with current theories and the results have major implications for fisheries, the value placed on marine protected areas, the impacts of climate change and the 20% of people globally who rely on fish for protein.

School visit

The Centre’s Belinda Comerford and Liz Morris visited the grade 5/6 students at Windsor Primary School.

Focus on PhD research

Amanda Petterson has graduated and moved to Sweden, Alex Gangur is growing copepods in chemostats, Lukas Schuster is comparing metabolic rates of bryozoans under different conditions, and Hayley Cameron wants to know if it’s better for a marine invertebrate to bigger (and fewer) or smaller (and many) when it comes to competing with siblings.

MacArthur or MacMartha? Mixed support for MacArthur’s minimisation principle

Despite the importance of Robert MacArthur’s niche theory to community ecology, it has received very little testing in real world situations. Giulia Ghedini and colleagues have used a well described and easily manipulated marine invertebrate model system to test this theory.

Do good things come in small packages?

Martino Malerba and colleagues have used the artificially evolved large and small plankton cells to assess how efficiently cells of different sizes can utilise light, and if differences are predicted by current theories.

Quality as well as quantity can change as an evolutionary response to intensive harvesting of algae

Dustin Marshall and Kenre Monro were among a team of researchers investigated whether the productivity of desirable algal biochemicals, such as fatty- and amino acids, evolve differently depending on harvesting regimes.

The energetics of fish growth

A new study led by Diego Barneche examining the theoretical underpinning of the growth patterns in fish, has found that the ‘cost of growth’ is paramount to determining how energy moves between levels in the food chain.
