The panopeid crab Dyspanopeus sayi (Smith, 1869) is reported here from the Ebro Delta (Mediterranean coast of the Iberian Peninsula). Originally endemic to the Atlantic coast of North America, D. sayiz was involuntarily introduced into Britain, France and the Netherlands, and into the Adriatic and Black Sea within the last thirty years. Here we provide the first record of this species from the western Mediterranean Sea. Occurrences of ovigerous females at different localities of the delta and…

Morphology of the larval stages of a Mediterranean population of the allochthonous Say's mud crab, Dyspanopeus sayi (Decapoda: Brachyura: Panopeidae)

Differences were found in both zoeal and megalopal larval characters between D. sayi and the other two species, which could raise doubt about their placement in the same family.

Annotated checklist of brachyuran crabs (Crustacea: Decapoda) of the Iberian Peninsula (SW Europe)

Although descriptions of crab species new to science are not expected to occur at a significant rate, an increase in the number of species in the Iberian Peninsula is expected to result from the introduction of alien species.

The tropical African hermit crab Pagurus mbizi (Crustacea, Decapoda, Paguridae) in the Western Mediterranean Sea: a new alien species or filling gaps in the knowledge of the distribution?

The first occurrence in the European Mediterranean Sea of a tropical Atlantic hermit crab, Pagurus mbizi, is reported, based on the capture of twenty specimens collected along the northern shores of the Alboran Sea, which proof the existence of a well-established population of this species, and the importance of this geographic area as a transitional and settlement zone for Atlantic species, which makes the Albouran Sea one of the richest marine biodiversity areas in the Mediterranean Sea.

Determination of evolutionary units in European representatives of the crab genus Pilumnus

The authors' results give evidence for five genetic clusters within the P. hirtellus complex, and these units are relatively young and possibly allow to study ongoing processes of morphological, genetic, and ecological differentiation, leading to speciation and radiations in the coastal marine environment.

Role of ships’ hull fouling and tropicalization process on European carcinofauna: new records in Galician waters (NW Spain)

According to evidence presented in the present study, biofouling still remains an important vector of species transmission and surely has been undervalued with respect to ballast water.

New Mediterranean Biodiversity Records (December 2012)

This paper presents records extending or confirming the distribution of Mediterranean species. Three alien algae are included, namely Codium taylorii reported for the first time from the Aegean and

Resurrection and neotype designation of Pilumnus spinulosus Kessler, 1861 (Crustacea: Decapoda)

Recently published data revealed the presence of only one species along the northern coastline of the Black Sea, namely Pilumnus aestuarii Nardo, 1869, and resurrected the older name, P. spinulosus Kessler, 1861, for the representatives of the brachyuran genus PilumnUS Leach, 1816 (Decapoda: Brachyura: Pilumnidae).

On the taxonomic identity of the representatives of the brachyuran genus Pilumnus Leach, 1816 (Decapoda: Brachyura: Pilumnidae) occurring along the Russian coasts of the Black Sea

Investigations and inventory of decapod fauna in the Azov – Black Sea basin have been carried out since the XVIII century and presently consists of 28 marine species with valid names, including a widespread representative of the brachyuran genus Pilumnus Leach, 1816 occurring along the Russian coasts of the Black Sea.

New Mediterranean Marine biodiversity records (April, 2014)

According to reports, the following 16 species have extended their distribution to other Mediterranean areas or have made a new appearance in other regions. The first category includes the following



High regional differentiation in a North American crab species throughout its native range and invaded European waters: a phylogeographic analysis

Rhithropanopeus harrisii (Gould 1841) has a native distribution from New Brunswick (Canada) to Veracruz (Mexico) and is considered an invasive species in northwestern North American (Oregon and

First record of Say's mud crab Dyspanopeus sayi (Brachyura: Xanthoidea: Panopeidae) from the Black Sea

Say's mud crab Dyspanopeus sayi already has a well-established population in the Romanian Black Sea and it might spread to the whole of the Black and Azov Seas and the adjacent estuaries, deltas and limans.

Current status and perspectives of mollusc (bivalves and gastropods) culture in the Spanish Mediterranean

This is a review of the current status, problems and perspectives of bivalve and gastropod culture in the Spanish Mediterranean. Along this coast, bivalve culture has traditionally been located in

Molecular phylogeny of mud crabs (Brachyura: Panopeidae) from the northwestern Atlantic and the role of morphological stasis and convergence

It is suggested that convergence or morphological stasis are responsible for the phenotypic similarities between divergent evolutionary lineages.

Genetic comparisons of German populations of the stone crayfish, Austropotamobius torrentium (Crustacea: Astacidae)

It is shown that in German populations rare haplotypes are not randomly distributed, but found in higher frequencies in the Bavarian Alps of the Allgau and in adjacent Tyrol, resulting in a relatively high F ST value.

Introduction, dispersal and potential impacts of the green crab Carcinus maenas in San Francisco Bay, California

The North Atlantic portunid crab Carcinus maenas has invaded the North Pacific Ocean following more than two centuries of global dispersal due to human activities and its eurytopic nature, its high breeding potential, and its diet and feeding behavior suggest the potential for extensive ecosystem alterations through predator-prey interactions, competition, disturbance, and indirect effects.


The xanthid crab Dyspanopeus sayi, common on oyster beds of the North-American Atlantic coast, is reported for the first time in the Mediterranean Sea on the basis of two adult males collected in the

Comparative vulnerability to predators, and induced defense responses, of eastern oysters Crassostrea virginica and non-native Crassostrea ariakensis oysters in Chesapeake Bay

It is concluded that the natural suite of crab and flatworm predators in Chesapeake Bay will likely serve to control the abundance of feral C. ariakensis and may be able to compensate for its greater vulnerability to crab predation and hence become a nuisance species.

Exotic species in Lesina and Varano lakes new guest in lesina and varao lakes: Gargano National Park (Italy)

The presence of Oreochromisniloticus niloticus and Procambarus clarkii seemed to be linked to the accidental release from aquaculture activities present in the sourronding land, while the presence of Musculista senhousia, Rapana venosa and Dyspanopeus sayi was probably due to the introduction into the lake of the juvenile mussels coming from the northern Adriatic sea.
