Ecosystems are complex machineries, and our ability to predict how multiple drivers and environmental forcing structure communities are limited. One way to represent and understand organisms, communities and ecosystems is to think in terms of 'traits' rather than species, and how the dominant traits emerge in an evolutionary and ecological...
In the oceans, a nearly constant biomass of organisms is found in equal log- intervals of body-size. This large-scale regularity is referred to as the size spectrum. In this new modelling study, we find that parameters of the size spectrum correlate strongly with the export and export efficiency of particles into the deep ocean. These...
Organisms adapt to predation risk by changing their behavior. A new study from the Centre for Ocean Life demonstrates how defensive behaviors of marine pelagic organisms, from phytoplankton to fish, may significantly change the intensity of the biological carbon pump and, hence the ability of the ocean to sequester carbon.
On 27 November 2020, Camila Serra Pompei will defend her PhD thesis. The defence can be watched online.
Most models of plankton communities, such as NPZ-type models, ignore the life-cycle (ontogeny) of multicellular zooplankton. Here, we propose a model framework along the Nutrient–Unicellular–Multicellular axis – a “NUM” framework – which incorporates zooplankton ontogeny.
Three PhD students at the Ocean Life Centre will defend their dissertations in the coming weeks giving us all something to look forward to as 2020 draws to a close.
Increases in temperature increase enzymatic activity, so one expects growth to also increase. However, this is not always the case. We show that when organisms are resource-limited, an increase in temperature can actually reduce growth, but these physiological effects do not directly translate into a community response.
We welcome two new PhD students at the Centre for Ocean life!
