Killer storms: North Atlantic hurricanes and disease outbreaks in sea urchins
(2010-11)
An increase in the incidence of disease in various marine organisms over the past few decades
has been linked to ocean climate change. In Nova Scotia, Canada, mass mortalities of sea urchins,
due to an amoebic disease, ...
Behaviour of sea urchin Strongylocentrotus droebachiensis grazing fronts: food-mediated aggregation and density-dependent facilitation
(2007)
The occurrence of destructive grazing fronts is a common phenomenon in sea urchins, but
mechanisms governing front formation and dynamics remain poorly understood. We experimentally
examined the effect of kelp biomass ...
Modelling phase shifts in a rocky subtidal ecosystem
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, [mailto:ir@int-res.com],
[URL:http://www.int-res.com/], 2008-03)
The rocky subtidal ecosystem of the Atlantic coast of Nova Scotia is characterised by 2
community states, kelp beds and urchin barrens that alternate on a decadal time scale. While the
shift from barrens to a kelp bed ...
Spatial dynamics, ecological thresholds and phase shifts: modelling grazer aggregation and gap formation in kelp beds
(2010)
On the Atlantic coast of Nova Scotia, transitions between alternative states of the subtidal
ecosystem, kelp beds and sea urchin barrens, occur on a decadal scale. To explore the process of
urchin aggregation within kelp ...
Modelling phase shifts in a rocky subtidal ecosystem
(2009)
The rocky subtidal ecosystem of the Atlantic coast of Nova Scotia is characterised by 2
community states, kelp beds and urchin barrens that alternate on a decadal time scale. While the
shift from barrens to a kelp bed ...
