Abstract. Brooding is a widespread phenomenon among Antarctic bivalves. Although it should represent a handicap to dispersion, many brooding species have achieved a wide distribution in Antarctic and subantarctic waters, suggesting that they have alternative and effective methods of dispersal. Evidence of such an alternative method is presented here for the bivalve Mysella charcoti, unexpectedly found alive and healthy in feces expelled by Nototheniacoriiceps (Nototheniidae: Pisces).

Growth and reproduction in the Antarctic brooding bivalve Adacnarca nitens (Philobryidae) from the Ross Sea
TLDR
The population showed a log–normal distribution and results suggest non-periodic reproduction with continuous embryonic development in A. nitens, which shows low fecundity and large egg size, common to other brooding species. Expand
Effects of capability for dispersal on the evolution of diversity in Antarctic benthos.

  • Medicine, Biology
  • Integrative and comparative biology
  • 2012
TLDR
Differences in early life-history patterns are key to the resilience potential of species in response to late Cenozoic glacial periods and it is proposed that there is a direct relationship between rate of speciation and the ability of taxa to disperse. Expand
Biology and functional morphology of the pallial organs of the Antarctic bivalve Mysella charcoti (Lamy, 1906) (Galeommatoidea: Lasaeidae)
TLDR
The role of the foot and its ciliature during the processes of dislodgement and burrowing within the sediment are described and M. charcoti is the first known lasaeid with ctenidia formed of the descending lamellae of the inner demibranchs only. Expand
A comparative study of the Bivalvia (Mollusca) from the continental shelves of Antarctica and Brazil
TLDR
The present paper can be a starting point for future discussion on the existing latitudinal gradients along the coast of eastern South America, stimulating studies on changes occurring in the composition of the faunas of bivalves from Brazil, Uruguay, Argentina, and Antarctica. Expand
Invasive zebra mussels (Driessena polymorpha) and Asian clams (Corbicula fluminea) survive gut passage of migratory fish species: implications for dispersal
TLDR
The potential for blue catfish to serve as a dispersal vector for invasive bivalves at low water temperatures at lowWater temperatures is demonstrated. Expand
Differential adaptations between cold-stenothermal environments in the bivalve Lissarca cf. miliaris (Philobryidae) from the Scotia Sea islands and Antarctic Peninsula
TLDR
Variations in physical traits appear to be underestimated in the Southern Ocean, but may be important drivers of ecological divergence and speciation, which should be considered in future genetic investigations on different invertebrate populations. Expand
The anatomical characters related to the brooding behavior of two Antarctic species of Mysella Angas, 1877 (Bivalvia, Galeommatoidea, Lasaeidae), with direct and indirect evidences of ovoviviparity
TLDR
Detailed anatomical characters related to brooding may be useful in future systematic studies of Antarctic Bivalvia. Expand
The Evolutionary Ecology of Biotic Association in a Megadiverse Bivalve Superfamily: Sponsorship Required for Permanent Residency in Sediment
TLDR
The evolution of biotic associations with infaunal bioturbating hosts may have been a prerequisite for the diversification of Galeommatoidea in sediments and has likely been a key factor in the success of this exceptionally diverse bivalve superfamily. Expand
Microbivalves from the Monte Leon Formation (Early Miocene), Patagonia, Argentina
Three new species (Mysella donaciformis n. sp., Cosa helianthea n. sp., and Lissarca saraballentae n. sp.) of small bivalves are described from early Miocene rocks in southern Patagonia. The outcropsExpand
Phylogeography of the intertidal marine bivalve Lasaea hinemoa (Mollusca: Bivalvia) in New Zealand
ABSTRACT Genetic investigations of members of the bivalve genus Lasaea have revealed unexpected diversity in the genus, as well as close affiliations between geographically distant populations. HereExpand

Long-distance dispersal of a subantarctic brooding bivalve (Gaimardia trapesina) by kelp-rafting
TLDR
Evidence of long-distance dispersal of a brooding pelecypod, Gaimardia trapesina, in the Southern Ocean and the prevalence of kelp rafts collected during the austral winter of 1993 indicate that dispersal by rafting can occur over ecologically relevant time scales and could potentially serve as a significant means of genetic exchange between populations. Expand
Role of the Gastropod Shell and Operculum in Inhibiting Predation by Fishes
TLDR
Asemichthys adjusted its punching behavior in an apparently adaptive way; other prey lacking such barriers to digestion were rarely punched, and the ability of shelled mollusks to survive in the digestive tracts of vertebrates may provide a dispersal mechanism for otherwise sedentary species. Expand
Notes on the reproduction of high-Antarctic molluscs from the Weddell Sea
SummaryThe reproductive modes of 66 molluscan species from the Weddell Sea, Antarctica were investigated either by rearing of specimens in aquaria (“Neomeniomorpha” [Solenogastres], PolyplacophoraExpand
Notes on the reproduction of high-Antarctic molluscs from the Weddell Sea
TLDR
The results show that not all marine invertebrates living in cold water environments produce large eggs, provide postspawning parental care or lack planktonic larvae (Thorson’s rule), nor that brooding behaviour is always associated with small adult size. Expand
Drifting and dispersal of small bivalves and gastropods with direct development
TLDR
Quantitative evidence that several marine benthic invertebrates lacking a planktonic larval stage disperse as juveniles and small adults by drifting in the water column has been obtained using off-bottom intertidal collectors, and it is probable that frequent drifting excursions in these taxa enhance rafting opportunities, which in turn may favor long distance dispersal. Expand
Reproductive adaptations of Antarctic benthic invertebrates
TLDR
The majority of Antarctic benthic invertebrates so far studied do not produce pelagic larvae, but develop non-pelagically by means of egg capsules, brooding or viviparity, which may partially compensate for this in the Antarctic. Expand
Types of larval development in marine bottom invertebrates, their distribution and ecological significance: a re-evaluation
TLDR
The distributional patterns of the various types of development among marine bottom invertebrates form one of the most important factors determining the basic distributional dynamics of the whole benthos in all oceans, both in the geological past and at the present time. Expand
Experimental studies on the response of the fish (Notothenia coriiceps Richardson, 1844) to parasite (Pseudoterranova decipiens Krabbe, 1878) and other irritant stimuli at Antarctic temperatures
TLDR
The immune response of N. coriiceps does not appear able to eliminate the infection and the fish in nature appear to suffer no adverse clinical effects. Expand
