| description | <p>Biodiversity of phytoplankton is important for ecosystem
stability and marine biogeochemistry. However, the large-scale patterns of
diversity are not well understood and are often poorly characterized in
terms of statistical relationships with factors such as latitude,
temperature and productivity. Here we use ecological theory and a global
trait-based ecosystem model to provide mechanistic understanding of patterns
of phytoplankton diversity. Our study suggests that phytoplankton diversity
across three dimensions of trait space (size, biogeochemical function and
thermal tolerance) is controlled by disparate combinations of drivers: the
supply rate of the limiting resource, the imbalance in different resource
supplies relative to competing phytoplankton demands, size-selective
grazing and transport by the moving ocean. Using sensitivity studies we
show that each dimension of diversity is controlled by different drivers.
Models including only one (or two) of the trait dimensions will have
different patterns of diversity than one which incorporates another trait
dimension. We use the results of our model exploration to infer the controls
on the diversity patterns derived from field observations along meridional
transects in the Atlantic and to explain why different taxa and size classes
have differing patterns.</p> |
