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 ... -
Temperature-mediated outbreak dynamics of the invasive bryozoan Membranipora membranacea in Nova Scotian kelp beds
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 ... -
Temporal and spatial variability in settlement and recruitment of echinoderms in kelp beds and barrens in Nova Scotia
Settlement and recruitment of echinoderms were measured in 2 adjacent habitats: a kelp bed (Laminaria longicruris) and an echinoid (Strongylocentrotus droebachiensis)-dominated barren ground at each of 2 sites 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 ... -
Variation in egg spawning among subpopulations of sea urchins Strongylocentrotus droebachiensis: a theoretical approach
Variation in zygote production, by determining the initial size of the larvalpool, can aff ect the population dynamics of marine invertebrates with a planktonic larval stage. In this paper, we model temporal and spatial ... -
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 ...
