Gene flow of Acanthaster planci (L.) in relation to ocean currents revealed by microsatellite analysis
TLDR
The results suggest that the western boundary currents have strong influence on gene flow of this species and may trigger secondary outbreaks of coral‐eating starfish.
Phylogeography of the Crown-of-Thorns Starfish in the Indian Ocean
TLDR
This first Indian Ocean-wide genetic study of a marine organism is investigated and inferred the paleohistory of the two Indian Ocean sister-species of Acanthaster planci using mitochondrial DNA sequence analyses, suggesting that the first of two main diversification events led to the formation of a Southern and Northern Indian Ocean daughter species in the late Pliocene-early Pleistocene.
Is the southern crab Halicarcinus planatus (Fabricius, 1775) the next invader of Antarctica?
TLDR
While this species is presently unable to survive in Antarctica, future warming under both strong mitigation' and 'no mitigation' greenhouse gas emissions scenarios will favour its niche expansion to the Western Antarctic Peninsula (WAP) by 2100.
Divergence time estimations and contrasting patterns of genetic diversity between Antarctic and southern South America benthic invertebrates
TLDR
Las comparaciones geneticas indican that especies antarticas y subantarticas fueron diferencialmente afectadas por los periodos glaciales, y el presente estudio provee nueva evidencia of los procesos de difererciacion entre organismos antarticos y sudamericanos.
Fine-grained habitat-associated genetic connectivity in an admixed population of mussels in the small isolated Kerguelen Islands
TLDR
It is demonstrated that the Kerguelen mussels were significantly differentiated over small spatial distance, and that this local genetic structure was associated with environmental variations and mostly revealed by ancestry-informative markers.
Does natural selection explain the fine scale genetic structure at the nuclear exon Glu-5′ in blue mussels from Kerguelen?
TLDR
Power simulations and confidence intervals support that Glu-5′ displays significantly higher differentiation than the other loci (except a single allozyme for which confidence intervals overlap) and AMOVA analyses revealed significant effects of the giant kelp Macrocystis and wave exposure on this marker.
