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.

Food and chemical cues can both drive changes in metabolic rates

Conspecific chemical cues drive density-dependent metabolic suppression independently of resource intake

Melanie Lovass and supervisors Dustin Marshall and Giulia Ghedini have run a series of experiments to test if competition for food in crowded conditions reduces food intake and, in turn, metabolic rates.

Estimating energy use in communities

Giulia Ghedini, Martino Malerba and Dustin Marshall estimate the energy use of a community using six different approaches.

How to estimate community energy flux? A comparison of approaches reveals that size-abundance trade-offs alter the scaling of community energy flux

Cell size, genome size and the selfish gene

In one of the first tests of the ‘selfish gene’ theory, Martino Malerba, Giulia Ghedini and Dustin Marshall have found direct evidence that smaller genome size is associated with fitness benefits in a species of marine microalgae.

Genome size affects fitness in the eukaryotic alga Dunaliella tertiolecta

‘Oh, the places you’ll go.’ How far can marine larvae travel?

Mariana Noriega and Dustin Marshall have been working with colleagues from the United States to examine existing data to help them grasp how larval dispersal distance changes on a global scale.
