Abstract Population outbreaks of the coral‐eating starfish, Acanthaster planci , are hypothesized to spread many localities in Indo‐Pacific Ocean through dispersal planktonic larvae. To elucidate gene flow A. across relation ocean currents and test larval hypothesis, genetic structure among 23 samples over was analysed using seven highly polymorphic microsatellite loci. The F ‐statistics admixture analysis detected genetically distinct groups accordance with current systems, that is,...
Background Understanding the limits and population dynamics of closely related sibling species in marine realm is particularly relevant organisms that require management. The crown-of-thorns starfish Acanthaster planci, recently shown to be a complex at least four species, coral predator infamous for its outbreaks have devastated reefs throughout much Indo-Pacific distribution. Methodology/Principal Findings In this first Indian Ocean-wide genetic study organism we investigated structure...

Abstract The potential for biological colonization of Antarctic shores is an increasingly important topic in the context anthropogenic warming. Successful invasions to date have been recorded exclusively from terrestrial habitats. While non‐native marine species such as crabs, mussels and tunicates already reported coasts, none yet established there. Among invaders shallow waters Halicarcinus planatus (Fabricius, 1775), a crab with circum‐Subantarctic distribution substantial larval...
How the near-shore marine benthic communities survived Quaternary glaciations in Antarctica is a major question for Southern Ocean biogeographers. Several hypotheses that consider life-history traits, such as bathymetric ranges and developmental modes, have been proposed. Near-shore species with high dispersive potential are expected to show star-like genealogies, broadly distributed haplotypes surrounded by closely related variants at low frequencies, consequence of rapid population...
Understanding the factors that sculpt fish gut microbiome is challenging, especially in natural populations characterized by high environmental and host genomic complexity. However, closely related hosts are valuable models for deciphering contribution of evolutionary history to assembly, through underscoring phylosymbiosis co-phylogeny patterns. Here, we propose recent diversification several
Connectivity is a fundamental process of population dynamics in marine ecosystems. In the last decade, with emergence new methods, combining different approaches to understand patterns connectivity among populations and their regulation has become increasingly feasible. The Western Antarctic Peninsula (WAP) characterized by complex oceanographic dynamics, where local conditions could act as barriers connectivity. Here, notothenioid fish Harpagifer antarcticus, demersal species life cycle...
One of the most relevant characteristics extant Southern Ocean fauna is its resiliency to survive glacial processes Quaternary. These climatic events produced catastrophic habitat reductions and forced some marine benthic species move, adapt or go extinct. The inhabiting Antarctic upper continental shelf faced Quaternary glaciations with different strategies that drastically modified population sizes thus affected amount distribution intraspecific genetic variation. Here we present new...
Interactions between algae and herbivores can be affected by various factors, such as seasonality habitat structure. Among inhabiting marine systems, species of the order Patellogastropoda are considered key organisms in many rocky coasts world. Nacella one most dominant macro-herbivores on shores sub-Antarctic ecoregion Magellan. However, importance its role must associated with trophic ecology. The objective this work was to evaluate spatial temporal variabilities dietary composition two...

The irregular coastline Patagonia expanding for more than 84.000 km constitutes a remarkable area to evaluate effect Quaternary landscape seascape shifts over demography near-shore marine benthic organisms. Few studies describing biogeographic responses species LGM have been conducted in Patagonia, but existing data from coastal...

Animal mitochondria are usually inherited through the maternal lineage. The exceptional system allowing fathers to transmit their offspring exists in some bivalves. Its taxonomic spread is poorly understood and new mitogenomic data needed fill gap. Here, we present for first time two divergent mitogenomes from Chilean mussel Perumytilus purpuratus. existence of these sex-specific confirms that this species has doubly uniparental inheritance (DUI) mitochondria. genetic distance between...
Abstract Reticulated evolution -i.e. secondary introgression / admixture between sister taxa-is increasingly recognized as playing a key role in structuring infra-specific genetic variation and revealing cryptic connectivity patterns. When zones coincide with ecological transitions, the patterns often follow environmental variations better than distance clines may easily be confounded local adaptation signatures. The Kerguelen mussels is an ideal system to investigate potential of enhancing...
The Kerguelen archipelago, isolated in the Southern Ocean, shelters a blue mussel Mytilus metapopulation far from any influence of continental populations or known hybrid zone. finely carved coast leads to highly heterogeneous habitat. We investigated impact environment on genetic structure those mussels by relating allele frequencies habitat descriptors. A total sample comprising up 2248 individuals 35 locations was characterized using two nuclear markers, mac-1 and Glu-5', mitochondrial...
