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, ...
Disease outbreaks associated with recent hurricanes cause mass mortality of sea urchins in Nova Scotia
(2010)
Field observations and laboratory experiments support the hypothesis that disease-induced mass
mortality of the sea urchin Strongylocentrotus droebachiensis can be associated with hurricane
events that introduce a ...
Fatty acids as dietary tracers in benthic food webs
(Inter-Research, Nordbuente 23 Oldendorf/Luhe 21385 Germany, 2011)
Fatty acid (FA) analysis is a well-established tool for studying trophic interactions in marine
habitats. However, its application to benthic food webs poses 2 particular challenges. First, unlike
pelagic zooplankton, ...
Detrital production in Nova Scotian kelp beds: patterns and processes
(2011)
Connectivity via the transport of detrital material from areas of high to low productivity may
be an important determinant of secondary productivity and biodiversity in receiving communities. On
the Atlantic coast of ...
Invasion-mediated shifts in the macrobenthic assemblage of a rocky subtidal ecosystem
(2011)
We tracked changes in community composition that occurred with state shifts in the rocky
subtidal ecosystem in Nova Scotia, Canada, from 1992 to 2008. At the beginning of our study, a dense
aggregation of sea urchins was ...
Spatial and temporal variation in DMSP content in the invasive seaweed Codium fragile ssp fragile: effects of temperature, light and grazing
(2010)
The methionine-derived secondary metabolite dimethylsulfoniopropionate (DMSP) is believed to
function in cryoprotection, defense against herbivory, and reduction of oxidative stress in some
seaweeds. The ability to produce ...
