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.

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.

Understanding how age and sex can influence host-pathogen interactions

PhD student Stephen Gipson and supervisor Matt Hall used a series of experimental infection trials to investigate how males and females of the freshwater crustacean, Daphnia magna respond to infection by two strains of a pathogen, Pasteuria ramosa, to test whether the age and sex of the host is a source of variation governing the evolution of infectious disease.

How do mutations affect growth and fermentation rates in yeast?

Through the lens of evolutionary biology, Aysha Sezmis and colleagues are examining why the brewer’s yeast Saccharomyces cerevisiae converts glucose via a seemingly inefficient pathway.
