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 ...
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 ...
Fatty acids tracers for native and invasive macroalgae in an experimental food web
(2009)
We assessed the potential of fatty acid (FA) markers for tracing primary production from an
invasive green alga (Codium fragile ssp. fragile) and a native kelp (Saccharina longicruris) through
2 trophic levels in an ...
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 ...
Fecal production by sea urchins in native and invaded algal beds
(2009)
To examine the role of fecal production by the sea urchin Strongylocentrotus droobachiensis in
native and invaded algal assemblages in Nova Scotia, Canada, we examined the quantity (production
rate by urchin feeding ...
