Antarctic bottoms harbor stable, benthic communities, subjected to low temperatures. Environmental stability may promote the asexual (clonal) reproduction of sponges to maintain adapted genotypes to those particular conditions. Stylocordyla chupachups forms patchy populations across the Antarctic continental shelf. Individuals are mostly similar in size without distinct cohorts, which indicates fast growth of the new recruits. Settlement of incubated (clonal?) functional sponges may accelerate…

Population substructure and signals of divergent adaptive selection despite admixture in the sponge Dendrilla antarctica from shallow waters surrounding the Antarctic Peninsula

The study unveils an unexpectedly long‐distance larval dispersal exceptional in Porifera, broadening the use of genome‐wide markers within nonmodel Antarctic organisms.



Small-scale spatial genetic structure in Scopalina lophyropoda, an encrusting sponge with philopatric larval dispersal and frequent fission and fusion events

The spatial autocorrelation analyses elicited a pattern of strong SGS at the small scale, confirming the predic- tions of philopatric larval dispersal, which fosters isolation by distance, and contrast with the conspicuous lack of inbreeding detected in the populations, which is in agreement with recent data on other marine modular invertebrates and confirms that strong S GS does not necessarily imply inbreeding.

Genetic structure and diversity of the endangered bath sponge Spongia lamella

Transplanting specimens from areas with high values of genetic diversity to areas with low diversity values or to areas that have recently experienced demographic declines could reverse the local and global recession of this species.

High genetic diversity, phenotypic plasticity, and invasive potential of a recently introduced calcareous sponge, fast spreading across the Atlanto-Mediterranean basin

High genetic diversity, phenotypic local adaptation, and high reproduction rates altogether allow predicting the fast proliferation of P. magna in newly colonized regions and point to its strong invasive potential.

Microsatellites from sponge genomes: the number necessary for detecting genetic structure in Hemimycale columella populations

It is concluded that a few polymor- phic loci can detect structure in H. columella populations, but using 12 or more loci notably enhances the power of the analyses.

Finding the relevant scale: clonality and genetic structure in a marine invertebrate (Crambe crambe, Porifera)

It is concluded that asexual reproduction plays an important role in structuring populations in this species, and over and above the effects of clonality, a strong fine‐scale genetic structure was present at distances in the range of tens of centimetres, probably as a result of short dispersal of larvae.

Strong population structure in the marine sponge Crambe crambe (Poecilosclerida) as revealed by microsatellite markers

It is shown that microsatellites fulfil expectations, allowing a fine description of population structure at different geographical scales in the marine sponge Crambe crambe, and suggest the possibility of a recent colonization of the Atlantic range from the Mediterranean Sea.

Genetic structure of the Caribbean giant barrel sponge Xestospongia muta using the I3-M11 partition of COI

Hydrological features may play a major role in sponge colonization and need to be considered in future plans for management and conservation of these important components of coral reef ecosystems.

Genetic diversity of the imperilled bath sponge Spongia officinalis Linnaeus, 1759 across the Mediterranean Sea: patterns of population differentiation and implications for taxonomy and conservation

No genetic differentiation exists among the acknowledged Mediterranean morphotypes, and S. officinalis can be viewed as a single, morphologically variable species, and its genetic diversity is maintained high in most studied locations.
