Enzymatic survey of four populations of Atherina boyeri based on electrophoresis and the occurrence of a microsporidiosis
TLDR
Comparison of allelic frequencies at the polymorphic loci between fish populations of infected and healthy lagoons yielded no significant differences.Abstract:
Biochemical genetics of a Atherinid species, Atherina boyeri were undertaken to determine variability. Among the 17 loci studied, 7 were polymorphic, of which three were retained for a more detailed comparison of populations inhabiting the French Mediterranean coastal lagoons. A microsporidiosis is present in these fishes and is limited to certain lagoons. Comparison of allelic frequencies at the polymorphic loci between fish populations of infected and healthy lagoons yielded no significant differences. Several hypotheses are discussed and attempt to agree parasite distribution with genetical results.read more

The Evolutionary Significance of Genetic Diversity: Ecological, Demographic and Life History Correlates
TL;DR: The evolutionary significance of genetic diversity of proteins in nature remains controversial despite the numerous protein studies conducted electrophoretically during the last two decades.

Parasites as biological indicators of the population biology, migrations, diet, and phylogenetics of fish
TL;DR: This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about the response of the immune system to infectious disease.

Size-selective overwintering mortality in the sand smelt, Atherina boyeri Risso, and its role in population regulation
TL;DR: This conclusion supports the hypothesis that the density-dependent control on population size in the sand smelt is a limitation on the number of fish which can spawn at the optimum time, and any restriction on spawning ground availability at that time will result in overall population regulation.

On the reproductive biology of the sand smelt atherina boyeri risso pisces atherinidae and its evolutionary potential
Peter Henderson,Roger N. Bamber +1 more
TL;DR: This analysis of the reproductive strategy shows that A. boyeri can rapidly adapt its life history and morphology to environments ranging from freshwater to polyhaline coastal lagoons and oceanic waters, and the optimum strategy is shown to be tied to temperate seasonality.

TL;DR: Hybridization in Menidia appears to be related more to ecological similarity than to genetic similarity, and an intermediate population in Lake Palourde, southern Louisiana, suggests hybridization.

TL;DR: A most likely new microsporidia parasites Atherina boyeri Risso, 1810 is found from the lagoons south of Montpellier to the Berre lagoon and forms numerous cysts, as well as in the general cavity of the fish were it evolves into voluminous xenoma which present particular histological characteristics.
