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 ...
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 ...
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, ...
Procedural effects of prey tethering experiments: Predation of juvenile scallops by crabs and sea stars
(1994)
This study examines the effects of an experimental tethering procedure often used in field
predation experiments. In laboratory experiments, juvenile sea scallops Placopecten magellanicus,
either free or tethered, were ...
Role of early post-settlement mortality in recruitment of benthic marine invertebrates
(1997-08)
Newly settled invertebrates usually are subject to high rates of mortality (Type III
survivorship). Therefore, knowledge of early post-settlement events is critical in determining if
and when patterns of abundance and ...
Spatial and temporal variability of patterns of colonization by mussels (Mytilus trossulus, M-edulis) on a wave-exposed rocky shore
(1998)
Colonization rates of mussels (Mytilus trossulus and M. edulis) were measured on natural
substrata in tidepools and on emergent rock in recently ice-scoured and non-scoured regions of a
rocky shore near Halifax, Nova ...
Non-Occurrence of Free-Living Paramoeba-Invadens in Water and Sediments of Halifax Harbour Nova Scotia Canada
(1989)
Seawater and sediment samples from various sites in or near Halifax Harbour were cultured for
Paramoeba as were tissues of the natural sea urchin host Stronglyocentrotus droebachiensis sampled
from Halifax Harbour. An ...
Spatial heterogeneity of phytoplankton assemblages in tidepools: Effects of abiotic and biotic factors
(1996-01)
In any ecological system, the factors that regulate the abundance of species vary with spatial
scale; therefore, the sources of spatial variability should be described. We examined different
sources of variability in the ...
