Estimating fertilization success in marine benthic invertebrates: A case study with the tropical sea star Oreaster reticulatus
Several factors can influence fertilization success, and for marine broadcast spawners, the main constraint is rapid dilution of gametes. Because the measurement of fertilization success in the field is logistically ... -
Estimation of Temporal Variability in Populations
A common measure of the temporal variability of a population is the standard deviation of the logarithms of successive estimated population sizes, In(D-t). This measure overestimates true temporal variability (the standard ... -
Estimation of total body water in pinnipeds using hydrogen-isotope dilution
No abstract available. -
Evolutionary and ecological feedbacks of the survival cost of reproduction
Arguably the most fundamental of trade-offs in life-history evolution is the increase in natural mortality resulting from sexual maturity and reproduction. Despite its central importance, this increase in mortality, a ... -

Fatty acid profiles in the gonads of the sea urchin Strongylocentrotus droebachiensis on natural algal diets
We examined fatty acid (FA) compositions of gonads of the green sea urchin Strongylocentrotus droebachiensis collected from a grazing aggregation (front) at the edge of a kelp bed and from barrens dominated by coralline ... -
Fatty acids as dietary tracers in benthic food webs
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, ... -
Fatty acids tracers for native and invasive macroalgae in an experimental food web
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 ... -
Fecal production by sea urchins in native and invaded algal beds
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 ... -
Food-Web Structure of Seagrass Communities across Different Spatial Scales and Human Impacts
Seagrass beds provide important habitat for a wide range of marine species but are threatened by multiple human impacts in coastal waters. Although seagrass communities have been well-studied in the field, a quantification ... -

The Forces Acting on Swimming Squid
1. Analysis of cine fils and intramantle pressure records for squid Loligo opalescens Berry swimming in a tunnel respirometer provided estimates of all the forces acting in the horizontal and vertical planes for swimming ... -
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, ... -
Genomic islands of divergence and their consequences for the resolution of spatial structure in an exploited marine fish
As populations diverge, genomic regions associated with adaptation display elevated differentiation. These genomic islands of adaptive divergence can inform conservation efforts in exploited species, by refining the ... -
