Research fellow position: ecologist / evolutionary biologist

Professor Dustin Marshall is seeking an experienced ecologist / evolutionary biologist, who specialises in microalgal biology with a strong empirical background, to explore the ways in which size affects the structure and function of marine phytoplankton.

Research fellow position: marine larval biologist

Professor Dustin Marshall is seeking a marine larval biologist, with strong quantitative skills, to explore the ways in which temperature affects the energetics of development in marine invertebrates.

Are there any advantages to being smaller in higher temperatures?

Martino Malerba and Dustin Marshall examined evolved large and small algal cells to see if they could unambiguously assign any effects of temperature on size, to size alone. They wanted to find out if (and how) temperature affected fitness for different sized organisms.

Water temperatures and viscosity will both change with ocean warming but how will they affect male fertility in the tubeworm Galeolaria?

Evatt Chirgwin found that increased ocean temperatures and reduces seawater viscosity independently reduced male fertility, and together altered selection pressures on sperm morphology for the marine tubeworm Galeolaria.

Size and reproduction: compiling a database

Michaela Parascandalo is compiling a database of published research on more than 900 species across 10 phyla to adree sthe question: do larger individuals produce disproportionately more gametes / offspring than smaller individuals in taxa other than fish?

Everybody loves good neighbours, but what makes a good neighbour?

Hayley Cameron, Dustin Marshall and Tim Coulson examine how different species that rely on the same resources can co-exist. And it’s not all about competition.

Size and density mediate transitions between competition and facilitation

How can pathogens optimise both transmission and dispersal?

PhD student Louise Nørgaard and supervisors Ben Phillips and the Centre’s Matt Hall have found evidence of a pathogen that exploits the differences in size and behaviour of male and female hosts to optimize its own chance of successful infection.
