Global awareness of introduced species as one of the primary drivers of biodiversity change-causing environmental impacts, and economic and social effects-emphasizes the need to enhance our understanding of these species. Developing a comprehensive database will enable policymakers to identify global bioinvasion patterns and strengthen their capaci...
In this study, we conduct a morphological integrative analysis, using traditional techniques and micro-computed tomography imaging, on Septibranchia species. Specimens deposited in malacological collections and samples collected aboard the research vessels Puerto Deseado and Austral off Mar del Plata (~36°S), San Jorge Gulf (~46°), and Marine Prote...
Species of Eatoniellidae are typical members of shallow, cold waters of the Southern Hemisphere; however, very little is known about their biology. This work deals with the first description of spawns and developmental stages for the family. All samples were collected from Southern Argentina and were identified as Eatoniella turricula based on shel...

sp. nov. is described after material collected off Argentina in: the Mar del Plata Submarine Canyon (528–2212 m
depth), at 39◦53.381′S, 55◦52.197′W off Buenos Aires province (772 m depth), and in the Burdwood Bank
(approximately 54◦S i...
We describe the shell morphology of the prodissoconch and early postlarval shell of Aequipecten tehuelchus (d’Orbigny), Flexopecten felipponei (Dall), and Zygochlamys patagonica (King) from the southern coast of Argentina. Aequipecten tehuelchus has a nepioconch microsculpture with fine, dense, and regularly distributed pits. The byssal notch is in...
Pachyoliva Olsson, 1956, previously considered a subgenus of Olivella (Olividae: Olivellinae), is characterized by a unique propodial morphology that enables a suspension-feeding lifestyle. As shown here, radulae of the two extant Pachyoliva species carry rachidian teeth with convex cusp-bearing edges, differing from those of other Olivellinae. Whi...
A new genus of conoidean gastropods of the family Mangeliidae, Notopropebela gen. nov., is herein described to include N. profunda (Castellanos and Landoni, 1993) previously in the genus Propebela Iredale, 1918, and two new species from the deep waters off south-western Atlantic Argentine. This new genus is characterised by small rhomboid shells wi...
Patagorbitestella new genus is here proposed to include two extant and one fossil species: P. ponderi (Linse, 2002) new combination, P. patagonica (Simone and Zelaya, 2004) new combination, and P. leonensis new species, the last described from the Punta Entrada Member of Monte León Formation (50°21′25.4”S, 68°53′05.9″W, Aquitanian to lower Burdigal...
The impacts of biological invasions remain poorly known for some habitats, regions and taxa. To date, there has been no comprehensive effort to review and synthesize the impacts of invasive mollusc species in South America. In this paper, we provide a synoptic view on what is known on documented socio-ecological impacts of aquatic no-native mollusc...
In this paper, a taxonomic review of the bivalves of the genus Cuspidaria Nardo, 1840 from the southern southwestern Atlantic is conducted. Specimens deposited in malacological collections and samples collected onboard the R/V Puerto Deseado off Mar del Plata (36S) and MPA Namuncur/Burdwood Bank area (54S), between 200 and 3,000 m depth, are the fo...
Descripción y actividad del eMIAS (especialistas sobre Moluscos Introducidos en América del Sur)
The movement of species is among the most serious environmental threats of the new millennium, as the transplantation of species beyond their native or historical range has intensified in the last five decades. Traditionally, studies on bioinvasions have focused on species that have been introduced, deliberately or accidentally, to biogeographic re...

Cada uno de los inte...
In analyses of trophic networks, the complexities of animal communities often have to be reduced by grouping species that share similar features. Which group-defining features are most meaningful in a given context is a notoriously problematic question (Simberloff & Dayan, 1991; Wilson, 1999; Blondel, 2003; Blaum et al., 2011), even in seemingly si...
Pleurotoma patagonica d'Orbigny, 1841 has been placed in several genera and families since its original description, perhaps because the type material, presumed lost, was never revised after the original description and because of the chaotic systematics of conoidean gastropods. New specimens, matching the original description and illustration and...
With the biodiversity crisis continuing unchecked, we need to establish levels and drivers of extinction risk, and reassessments over time, to effectively allocate conservation resources and track progress towards global conservation targets. Given that threat appears particularly high in freshwaters, we assessed the extinction risk of 1428 randoml...
The nominal species referred to the endemic southern South American genus Buccinanops are revised, clarifying the definition of Buccinanopsinae. All valid Recent species are redescribed based on type material and other specimens emphasizing anatomy and illustrated using SEM photographs of radulae, embryos, and shell ultrastructure. Only seven of 13...
Macroplastic debris recorded in the Mariana Trench and accumulated on some deep-sea canyons worldwide has aroused great public concerns. Large plastic debris dumps found in canyons of the Xisha Trough, South China Sea have become hot spots for deep-sea pollution, with 1 order of magnitude higher abundance than in other investigated canyons. Here we...
Between 2012-2013 we study the reproductive mode of deep-sea invertebrates from the Southwestern Atlantic after a series of cruises on board of the B/O “Puerto Deseado”, with focus on the submarine canyon of Mar del Plata (about 38°S and up to 3,500 m depth). This region of the world is poorly known and is very interesting because like other deep-s...
Theta lyronuclea (Clarke, 1959), a North Atlantic deep-water species, is recorded for the first time from the southwestern Atlantic. This constitutes the first record of the genus and the second mention of the family Raphitomidae off Argentina. The samples were collected in the Mar del Plata Submarine Canyon on the Argentine Continental slope on bo...
Non-native species have been introduced at escalating rates during the last decades, mainly due to the dispersion generated by the increasing trade and transport worldwide. Mollusks, the second largest metazoan phylum in terms of species richness, are no exception to this pattern, but, to date, a comprehensive synthesis of non-native mollusk specie...
Spawn and specimens of Toledonia biplicata comb. nov. were collected from Burdwood Bank during March 2013. Species-level identification was derived from radular, shell and spawn characters. A low number of eggs laid per spawn (one to three), absence of an external gelatinous mass and a considerably thickened capsule wall (~50 µm) constitute a uniqu...

ABStRACt the anatomy and taxonomy of two western African nassariids are explored, based on samples collected in Morocco. the species are Dorsanum miran, the type species of the genus, and Bullia granulosa, a charac-teristic member of Bullia. Both possess the typical morphological and anatomical features of the family, including a pair of metapodial...
Biological diversity, or biodiversity, is defined as the variety and
variability of living beings and the ecological complex they are part of
(Wheeler 1990). One of these three components, the number of species
(variety) recognized fluctuates between 1.5 and 1.75 million (Crisci 2006).
A little over a million of these are animals and 96% of those a...
Muricid gastropod radulae are more complex than those of most other neogastropods, especially in the number and variety of cusps, denticles, and interlocking mechanisms. How this complexity evolved, however, is unknown. Morphological gaps between higher taxa within the Muricidae are substantial, and there are few unambiguous intermediates. Here, we...
The family Pteriidae is well represented in tropical and subtropical continental shelf regions. Two names belonging to the genus Pteria are usually recorded in the literature from the southwestern Atlantic: P. colymbus (Röding) and P. hirundo (Linnaeus). The study of living specimens sampled off Buenos Aires coast aboard of the R/V Puerto Deseado a...
A revision of the Cenozoic Ampullinidae and Naticidae from a wide range of localities and stratigraphic units in Patagonia revealed the occurrence there of thirteen species referable to these families. Ampullinid species described are Tejonia? tapia (Feruglio, 1935); Tejonia arroyoensis n. sp. and Pseudamaura dubia (Petersen, 1946). Naticids are re...
Intertidal communities from rocky shores of the southwestern Atlantic are dominated by
two small-sized mussels of the genus Brachidontes, B. rodriguezii (d’Orbigny, 1846) and B.
purpuratus (Lamarck, 1819). Their generic placement, separation of specimens based on
external conchological characters and geographic distribution are problematic. We cond...
The authors revised the Atlantic species of the genus Trochita. Two valid species are recognized. Trochita pileus (Lamarck, 1822) and T. pileolus (d'Orbigny, 1841) are redescribed and the type material of each species is illustrated. Both species range from the coast of Buenos Aires province to Tierra del Fuego. Trochita pileus is a common subtidal...
