Role of early post-settlement mortality in recruitment of benthic marine invertebrates
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
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 ...
Spatial heterogeneity of phytoplankton assemblages in tidepools: Effects of abiotic and biotic factors
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 ...
Top down and bottom-up regulation of phytoplankton assemblages in tidepools
We examined the relative importance of bottom-up (nutrient availability) and top-down (grazing) factors in regulating phytoplankton assemblages in tidepools on a rocky shore near Halifax, Nova Scotia, Canada. We manipulated ...
Community structure and organization of tidepools
Although tidepools are conspicuous components of rocky intertidal shores, their biotic communities have not been studied as extensively as those on emergent substrata. We examine processes regulating the structure of ...
Survival analysis of tethered juvenile sea scallops Placopecten magellanicus in field experiments: Effects of predators, scallop size and density, site and season
The impact of predation on survival of juvenile sea scallops Placopecten magellanicus has important implications for the population dynamics and aquaculture of this species. In field experiments using tethered juvenile ...
Free-Space Availability and Larval Substratum Selection as Determinants of Barnacle Population-Structure in a Developing Rocky Intertidal Community
Variation in settlement and recruitment of the barnacle Semibalanus balanoides (L.) was experimentally investigated in the high, mid and low intertidal zones at 2 adjacent sites (A and B) on a rocky shore in Nova Scotia, ...
Variations in Sampling Procedure and Frequency Affect Estimates of Recruitment of Barnacles
The influence of variations in sampling procedure and frequency on estimates of recruitment of the barnacle Semibalanus balanoides (L.) on an intertidal rocky shore at Sandy Cove, Nova Scotia, Canada was determined from ...
Spatial and Temporal Variability of Macrobenthic Communities in Tidepools on a Rocky Shore in Nova-Scotia, Canada
Spatial and temporal patterns in the distribution and abundance of macroalgae and macrofauna were measured in 4 pools in each of 3 intertidal zones (mid, high and splash) on a rocky shore near Halifax, Nova Scotia, Canada. ...
