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, ...
Temperature-mediated outbreak dynamics of the invasive bryozoan Membranipora membranacea in Nova Scotian kelp beds
(2009)
We used underwater videography to examine seasonal and interannual patterns in the cover (on
kelp) of the encrusting epiphytic bryozoan Membranipora membranacea, and associated changes in the
structure and abundance of ...
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 ...
Community Dynamics on a Subtidal Cobble Bed Following Mass Mortalities of Sea Urchins
(1990)
The macrobenthic community of a shallow subtidal cobble bed at Eagle Head on the Atlantic coast
of Nova Scotia [Canada] was monitored from ca 4 mo before to 41 mo after mass mortalities of sea
urchins Strongylocentrotus ...
Physical and biological factors influencing mussel (Mytilus trossulus, M. edulis) settlement on a wave-exposed rocky shore
(1996)
Settlement rates of mussels Mytilus trossulus and M. edulis on artificial collectors (aquarium
filter wool) and natural substrata were measured in tidepools and on emergent rock in recently
ice-scoured and non-scoured ...
Herbivory and community organization on a subtidal cobble bed
(2009)
We examined the role of molluscan mesograzers (periwinkles Littorina littorea, limpets
Testudinalia testudinalis and chitons Ischnochiton ruber) in mediating macroalgal succession after a
mass mortality of sea urchins ...
Recurrent outbreaks of disease in sea urchins Strongylocentrotus droebachiensis in Nova Scotia: Evidence for a link with large-scale meteorologic and oceanographic events
(1997-06)
Recurrent outbreaks of a disease (paramoebiasis, caused by a marine amoeba Paramoeba invadens)
result in mass mortalities of sea urchins Strongylocentrotus droebachiensis in the rocky subtidal
zone of the Atlantic coast ...
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, ...
Role of grazing by sea urchins Strongylocentrotus droebachiensis in regulating the invasive alga Codium fragile ssp tomentosoides in Nova Scotia
(2005)
To assess the potential of herbivory in regulating the invasive green alga Codium fragile ssp.
tomentosoides, field and laboratory experiments were conducted with the green sea urchin
Strongylocentrotus droebachiensis ...
Structure and dynamics of mussel patches in tidepools on a rocky shore in Nova Scotia, Canada
(1995)
The distribution, size structure, and dynamics of mussel (Mytilus trossulus, M. edulis) patches
in tidepools were studied on an exposed rocky shore near Halifax, Nova Scotia, Canada. The mussel
patches were dynamic, ...
