TLDR
Results show that the observed variance in reproductive success can be attributed to three main factors: gamete quality, sperm–egg interaction and differential viability among genotypes, and warn against using too limited a number of progenitors in breeding programmes.About:

Impact of ocean warming and ocean acidication on marine invertebrate life history stages: Vulnerabilities and potential for persistence in a changing ocean
TL;DR: To address questions of future vulnerabilities, data on the thermo- and pH/ pco2 tolerance of fertilization and development in marine invertebrates are reviewed in the context of the change in the oceans that are forecast to occur over the next 100-200 years.

TL;DR: While fertilization may remain unaffected by elevated pCO2, embryonic and larval development will be highly sensitive with important reductions in size and decreased survival of larvae, increases in the number of abnormal larvae and an increase in the developmental time.
Journal ArticleDOI
Global change ecotoxicology: Identification of early life history bottlenecks in marine invertebrates, variable species responses and variable experimental approaches.
TL;DR: Exposure to climate change stressors from early development (fertilization where possible) in multistressor experiments is needed to identify ontogenetic sensitivities and this will be facilitated by more consistent methodologies.

Summer mortality of hatchery-produced Pacific oyster spat (Crassostrea gigas). I. Estimation of genetic parameters for survival and growth
TL;DR: A strong genetic basis was found for survival as narrow-sense heritability estimates ranged from 0.47 to 1.08, with higher values in sites where summer mortality was higher, and genetic correlations between growth and survival were low, in all sites.
Book ChapterDOI
The ecological and evolutionary importance of maternal effects in the sea
TL;DR: Offspring size effects are strong and pervasive in the marine environment but the sources and underlying causes of offspring size variation remain poorly understood, and the authors suspect that changes in offspring phenotype are often adaptive maternal effects in response to environmental change.

A Simple Sequentially Rejective Multiple Test Procedure
TL;DR: In this paper, a simple and widely accepted multiple test procedure of the sequentially rejective type is presented, i.e. hypotheses are rejected one at a time until no further rejections can be done.
Book
Genetics and evolution of aquatic organisms
TL;DR: This chapter discusses DNA technology and genetics of aquatic invertebrates, as well as Chromosomal genetics, which are involved in speciation and wide scale genetic differentiation in fish.
Journal ArticleDOI
Inbreeding in artificial selection programmes.
TL;DR: In a population under artificial selection, the effective population size may be less than the actual number of parents selected because there will be variation between families in the character under selection and consequently in the probability of selection.

High genetic load in the Pacific oyster Crassostrea gigas.
Sophie Launey,Dennis Hedgecock +1 more
TL;DR: Evidence for a high genetic load strongly supports the dominance theory of heterosis and inbreeding depression and establishes the oyster as an animal model for understanding the genetic and physiological causes of these economically important phenomena.
Journal ArticleDOI
Comparison of microsatellites and amplified fragment length polymorphism markers for parentage analysis.
TL;DR: Comparing the properties of dominant markers, such as amplified fragment length polymorphisms (AFLPs), with those of codominant multiallelic markers,such as microsatellites, in reconstructing parentage shows dominant markers are less efficient thancodominant markers for achieving this, but can be used with good confidence.
