Mind the gap: a systematic map of light variation in algal aquaculture allows us to identify research gaps

PhD student Belinda Comerford, under the supervision of Nick Paul and Dustin Marshall, has explored existing studies on how variation in light affects algal growth, highlighting crucial gaps in our knowledge to date.

Mother-offspring conflicts: temperature can change selection on offspring size

Using the model organism Bugula neritina, more than four years of study and the deployment of over 6000 individuals, Dustin Marshall has found that mothers in higher temperatures tend to favour smaller offspring, while mothers in cooler temperatures favour larger offspring.

Challenging the karyoplasmic ratio: bigger cells, smaller nuclei

New work by Martino Malerba and Dustin Marshall debunks the long-held belief that the karyoplasmic ratio — the proportion of nucleus size to cell size — is approximately constant.

Plastic responses to changes in environment are not necessarily adaptive

Lukas Schuster and his supervisors, Craig White and Dustin Marshall, investigate whether changes in metabolic rates in response to different field environments are an example of adaptive phenotypic plasticity.
