The copepod invader Skistodiaptomus pallidus (Herrick, 1879) (Crustacea, Copepoda, Diaptomidae) from North America in water bodies of Bremen, northern Germany
(pp S1-S5)
|
|
The paper presents the first European records of the copepod (Crustacea, Calanoida, Diaptomidae) Skistodiaptomus pallidus in shallow eutrophic
waters indirectly connected with the Weser River, Northern Germany. Its original distribution is in the Mississippi basin of the United States of America.
It is probable that this species entered the Weser River via ship ballast.

Second records of the Lessepsian fish migrants Priacanthus sagittarius
and Platax teira and distribution extension of Tylerius spinosissimus in the Mediterranean
(pp S7-S11)
|
|
The Red Sea (Lessepsian) migrant fish, the arrow bulleye, Priacanthus sagittarius, and the spotbelly batfish, Platax teira,
are recorded for the second time from the Mediterranean, suggesting the establishment of new populations. The record of another
Lessepsian migrant, the spiny blaassop, Tylerius spinosissimus from Israel, constitutes a considerable extension of its distribution
range in the Mediterranean.

On the presence, distribution and habitat of the alien freshwater snail Ferrissia fragilis (Tryon, 1863)
(Gastropoda: Planorbidae) in the oceanic islands of the Azores
(pp S13-S17)
|
|
The present work reports on the presence and distribution of an alien and invasive gastropod, Ferrissia fragilis(Tryon, 1863),
in freshwater systems of the oceanic islands of the Azores archipelago. First registered in 2007, F. fragilis was found in S. Miguel,
Santa Maria, and Graciosa. This study increases to 6 the number of freshwater species of mollusks occurring in the Azores.
Remarks are added on the possible impact of invasive species in island freshwater systems.

First record of the Indo-Pacific burrowing goby Trypauchen vagina (Bloch and Schneider, 1801) in the North-Eastern Mediterranean Sea
(pp S19-S21)
|
|
This paper presents the first observation of a recent Lessepsian fish species, the burrowing goby, Trypauchen vagina (Bloch and Schneider, 1801)
in the North-Eastern Mediterranean Sea, where two specimens of burrowing goby were caught by a shrimp trammel net in Iskenderun Bay. This record
indicates the range extension of a possibly established population of burrowing goby in the Eastern Levant Basin.

First record of Diadema setosum (Leske, 1778) (Echinodermata, Echinoidea, Diadematidae) from Lebanon, Eastern Mediterranean
(pp S23-S25)
|
|
The Eastern Mediterranean basin is facing a high invasion rate of mainly Indo-Pacific species entering through the Suez Canal.
The needle-spined urchin, Diadema setosum, was first documented in the Mediterranean in 2006 off southern Turkey.
The new record of D. setosum in September 2009 represents the first evidence of its presence in Lebanese coastal waters.

First record of Phyllorhiza punctata von Lendenfeld, 1884 (Scyphozoa: Rhizostomeae: Mastigiidae) from Turkey
(pp S27-S28)
|
|
The Australian spotted jellyfish Phyllorhiza punctata has been reported from several locations
in the Mediterranean, but the present report is the first record from Turkish waters. Juveniles of
the Erythrean alien shrimp scad, Alepes djedaba, were observed nestling among its tentacles.
Possible vectors are mentioned.

The Australian redclaw crayfish Cherax quadricarinatus (von Martens, 1868) (Crustacea: Decapoda: Parastactidae) in the Sea of Galilee, Israel
(pp S29-S31)
|
|
The Australian redclaw crayfish, Cherax quadricarinatus, was introduced to Israel from the U.S.A.
in the early 1990s by the Department of Fisheries, Ministry of Agriculture, with no assessment of its potential
to establish feral populations. It has been raised in agricultural research and academic facilities and in commercial
farms. A warning against its introduction to the temperate part of the country has been ignored. We report the first
appearance of the redclaw in the Sea of Galilee, and discuss possible vectors.

Assessment of larval distribution of invasive Omobranchus punctatus (Valenciennes, 1836) (Pisces: Blenniidae) in a subtropical estuary (Southern Brazil)
(pp S33-S38)
|
|
The occurrence and spatio-temporal distribution of the larvae of exotic Blenniidae Omobranchus punctatus
(Valenciennes, 1836) was studied at Babitonga Bay, a subtropical estuary of Southern Brazilian Coast.
Samples were collected in 26 ichthyoplankton surveys (28 stations) from April 2004 to August 2008.
Oblique hauls were used, with both a conical plankton net fitted with 200µm mesh and by a cylindrical-conical
plankton net fitted with 500µm mesh (two and five minutes hauls, respectively). Larvae occurred continuously
throughout the sampling and an increase in density was observed in the period from November to April.
Specimens were registered throughout the study area. The occurrence of a wide range of ontogenetic stages
indicates that the species is maintaining the population within Babitonga Bay. The lack of information
about the potential impacts of O. punctatus in the ichthyoplankton assembly, with regard to ecological
interactions and the food chain suggests the need for further studies.

Occurrence of the non-native blenny Omobranchus punctatus (Valenciennes, 1836) (Perciformes:
Blenniidae) in the Amazon coastal zone, Brazil
(pp S39-S43)
|
|
The muzzled blenny Omobranchus punctatus (Valenciennes, 1836) is native to the Indo-Pacific region.
The species has been recorded at a number of locations in the southwestern Atlantic, including
the Brazilian states of Bahia, Santa Catarina, and Rio de Janeiro. This fish was probably introduced
accidentally in ship fouling, and poses a potential threat to the local ecosystem.

The invasion of Lake Orta (Italy) by the red swamp crayfish
Procambarus clarkii (Girard, 1852): a new threat to an unstable environment
(pp S45-S48)
|
|
Procambarus clarkii is an invasive, prolific and aggressive species introduced into Italy
for commercial use since the 1980s. In November 2010, this red swamp crayfish was detected in Lake Orta,
a large, deep, Italian subalpine lake. Well-known for its 80-year heavy pollution by copper, Lake Orta
has been gradually colonized by biota, after its chemical recovery in the 1980s. The lake is still far
from being comparable to other subalpine lakes for taxa composition and seasonal dynamics. Lake Orta
may be regarded as an unstable environment, in which the invasion by this voracious species deserves
particular attention. After the present early detection, we plan to perform interventions to minimize
negative impacts of P. clarkii to both the ecology and economy of the region. The latter may
be particularly important in the case of the Lake Orta because of a persistence of heavy metals in the sediments.

The occurrence of the Indo-Pacific swimming crab Scylla serrata (Forskål, 1775)
in the Southwestern Atlantic (Crustacea: Brachyura: Portunidae)
(pp S49-S51)
|
|
The Indo-Pacific swimming crab Scylla serrata (Forskål, 1775) is reported here for the second time
from the Southwestern Atlantic (Brazil). The species had been previously recorded from Brazil in the early 1980’s.
On both occasions individuals were captured near port areas.

First record of the Red Sea orangeface butterflyfish
Chaetodon larvatus Cuvier, 1831 in the Mediterranean
(pp S53-S55)
|
|
The Red Sea species, the orangeface butterflyfish, Chaetodon larvatus, is recorded
for the first time from the Mediterranean. Its occurrence there is evidentially
the result of entering the Mediterranean via the Suez Canal.

First record of the common carp Cyprinus carpio var. communis (Linnaeus, 1758)
and the mirror carp Cyprinus carpio var. specularis (Lacepède, 1803) in Tabasco,
Southern Gulf of Mexico
(pp S57-S60)
|
|
Cyprinus carpio is known to be established in most of Mexico. Only the Mexican Gulf states
were free of this species until recently. This paper reports the first record of the common carp
in Tabasco, Mexico. Seven specimens of Cyprinus carpio var. communis and one specimen
of Cyprinus carpio var. specularis were detected in a small scale fishing landing site
near Frontera, Tabasco on January 24, 2011. Further sampling and monitoring is required to assess
the ecological impacts of this exotic species on the native fauna.

First record of the Asian leech Barbronia weberi (Blanchard, 1897) (Hirudinea: Arhynchobdellida: Erpobdelliformes: Salifidae) in the Iberian Peninsula
(pp S61-S64)
|
|
Barbronia weberi, an Asian leech, was found in September-October 2010 in a river from Central Spain.
This is the first record of the species for the Iberian Peninsula and the Jarama River in particular, where
in September-October 2010 the leech was collected during sampling for a bioassessment program. On the program’s
completion we expect to observe the seasonal dynamic of B. weberi population in the Jarama River.

First evidence of Eriocheir sinensis reproduction from Schleswig—Holstein, Northern Germany, western Baltic Sea
(pp S65-S69)
|
|
Eriocheir sinensis invaded the Baltic Sea over 80 years ago, but there is still little known
about mitten crab reproduction in this region. According to present knowledge, reproduction does not
occur in the central, eastern and northern parts of the Baltic Sea due to the low salinity present.
Sufficient salinity levels for reproduction of the Chinese mitten crab may exist in the western part
and in the Kattegat, but published evidence of reproduction is still lacking from the region.
Recently however a total of 62 ovigerous females were collected in the eastern part of the Kiel Canal
(connecting the North Sea with the Baltic Sea) close to the Kiel Fjord as well as in the Kiel Fjord
itself (Schleswig-Holstein, German Baltic Sea coast). The eggs from some of these females were hatched
in the laboratory under ‘Kiel Fjord salinity conditions’ and reared to third zoeal stage. Furthermore,
larvae were found in plankton samples from the Kiel Fjord and juvenile crabs were present in a lake
close to this watershed.

Range expansion of the quagga mussel Dreissena rostriformis bugensis (Andrusov, 1897) in Western Europe: first observation from France
(pp S71-S74)
|
|
After the quagga mussel was found for the first time in Western Europe in 2006, upstream migration in the River Rhine
was observed. Navigation is expected to be an important vector for range expansion in this river. It was only a matter
of the time before the colonization of the navigable international River Moselle (a tributary of the River Rhine),
which rises in France. The species was found in March 2011 at three locations in the French section of the river.

(pp S75-S77)
|
|
The slender ponyfish Equulites elongatus was recorded for the first time in the Mediterranean
near Tel-Aviv, Israel on 27 May 2011. This Indo-Pacific species evidently reached the Mediterranean
by crossing the Suez Canal.

An overlooked and unexpected introduction? Occurrence of the spotted scat Scatophagus argus (Linnaeus, 1766) (Osteichthyes: Scatophagidae) in the Maltese Islands
(pp S79-S83)
|
|
The spotted scat Scatophagus argus (Linnaeus, 1766) is recorded for the first time from Malta and the Mediterranean
from fish offered for sale at a Maltese fish market. Interviews with fish sellers and fishermen showed that this fish is caught
occasionally in small numbers in trammel nets from shallows on seagrass meadows in the southeast of Malta and that it has been
present since at least 2007. The native range of the species is the Indian Ocean and the tropical to warm temperate Pacific
but the species is commercially available as a brackish water aquarium fish. Given that this species has also been regularly
imported into Malta by the aquarium trade since at least 1986, an escape or deliberate release by an aquarist seem to be
the most probably mode of introduction. It is surprising that this euryhaline species which requires brackish water to complete
its life cycle should have become established in Malta where there is a dearth of such habitats.

Non-indigenous Japanese oyster drill Pteropurpura (Ocinebrellus) inornata (Récluz, 1851) (Gastropoda: Muricidae) on the South-west coast of Portugal
(pp S85-S88)
|
|
The Japanese oyster drill or rock snail Pteropurpura (Ocinebrellus) inornata (Récluz, 1851),
a marine mollusc, belonging to the family Muricidae, is reported from Portugal for the first time. This non-indigenous species,
most likely introduced accidentally from French oyster rearing areas into mainland Portugal, has been regularly sampled
in shellfish-culture and nearby environments in Sagres, Algarve, South-west Portugal since 2005–2008. Detailed studies
are urgently needed in order to assess whether or not it has become an invasive species due to a range expansion beyond
its point of initial introduction. Outputs should provide information to decision-makers to predict and limit further spread
which might result in biodiversity loss and negative economical consequences in locally species-rich areas.

Not far behind: First record of Beroe ovata Mayer, 1912 (Ctenophora: Beroida: Beroidae) off the Mediterranean coast of Israel
(pp S89-S90)
|
|
The American brown comb jelly, Beroe ovata, was first noted off the Mediterranean coast of Israel on 10 June 2011,
outside the port of Ashdod. The occurrence of B. ovata soon after its prey, Mnemiopsis leidyi, had been recorded
follows the pattern of spread elsewhere, yet its presence in the warm and saline waters of the SE Levant is a surprise.

On the population of Chromodoris annulata Eliot, 1904 (Mollusca: Opistobranchia: Chromodorididae) off the Mediterranean coast of Israel
(pp S91-S93)
|
|
The Indian Ocean opisthobranch Chromodoris annulata was first noted off the Mediterranean coast of Israel in October 2009.
Early occasional sightings of single specimens were followed by increasingly frequent reports of clusters of specimens.
Our findings point to the presence of an established population along the Mediterranean coast of Israel.

The westernmost record of Rhopilema nomadica (Galil, 1990) in the Mediterranean – off the Maltese Islands
(pp S99-S103)
|
|
In late autumn and early winter of 2004, two individuals of the Erythrean alien Rhopilema nomadica
were sighted at two locations off the Maltese Islands, marking the westernmost records of this species
in the Mediterranean Sea. Since only two adult specimens were ever reported from Maltese waters,
in the species has yet to establish a reproducing population in the Sicily Channel. The record is
considered as yet another hallmark of the warming trend of the Mediterranean Sea.

Expansion of the invasive corals Tubastraea coccinea and Tubastraea tagusensis into the Tamoios Ecological Station Marine Protected Area, Brazil
(pp S105-S110)
|
|
The scleractinian corals Tubastraea coccinea Lesson, 1829 and Tubastraea tagusensis Wells, 1882
are the first alien corals to be introduced into the South Atlantic and threaten native marine organisms due
to their noxious attributes. This study aimed to determine the spatial distribution and relative abundance
of these species throughout the Tamoios Ecological Station Marine Protected Area (MPA). Monitoring was carried
out at 33 sites by two snorkel divers swimming parallel to the shore and observing the substrate, diagnosing
and visually estimating the relative abundance of both species on a scale: dominant, abundant, frequent,
occasional, rare or absent. The study presents new records which demonstrate that the MPA is being invaded
by both species and that T. tagusensis is leading the invasion from west to east. Most sites are near
the original probable point of introduction into the region.

First record of the spiny-cheek crayfish Orconectes limosus (Rafinesque, 1817) introduced to the Iberian Peninsula
(pp S111-S113)
|
|
This is the first record of the spiny-cheek crayfish, Orconectes limosus (Rafinesque, 1817),
introduced into the Iberian Peninsula. Sixteen individuals of this crayfish species were detected
in the Muga River, near to the Boadella Reservoir (Catalonia, NE Iberian Peninsula) on October 9, 2010.
This reservoir is only 14 km away from France, where the spiny-cheek crayfish was introduced during the 20th century.
The presence of this non-native crayfish is a pressure on the conservation of native crayfish populations
of this area and a problem for the whole aquatic ecosystem.

On the occurrence of the Indo-Pacific Champsodon nudivittis (Ogilby, 1895) (Perciformes, Champsodontidae)
from the Mediterranean coast of Israel, and the presence of the species in the Red Sea
(pp S115-S117)
|
|
The Indo West Pacific nakedband gaper, Champsodon nudivittis, is recorded for the first time from Israel
on the basis of a single specimen collected off Ashdod, southern Israel. This species was previously recorded
in the Mediterranean from eastern Turkey. Examination of Champsodon specimens deposited in the National
Collection at Tel Aviv University revealed the previously unknown presence of C. nudivittis in the Red Sea.
This presence suggests the species may have entered the Mediterranean through the Suez Canal.

The Chinese pond mussel Sinanodonta woodiana is an invasive bivalve species present in the flowing
and standing waters of most of Europe. Field research conducted from 2007 to 2011 indicated that this species
has colonised the entire eastern part of Croatia, and that its spread westward is continuing. During our study,
S. woodiana was recorded at 54 localities.

Occurrence of the Malabar grouper Epinephelus malabaricus (Bloch & Schneider, 1801) (Actinopterygii, Perciformes, Serranidae), in the Maltese Islands
(pp S129-S132)
|

The capture of a single specimen of the Malabar grouper Epinephelus malabaricus (Bloch & Schneider, 1801)
from inside the breakwater at the entrance to the Grand Harbour at Valletta, Malta in July 2011 is reported here.
Previously this Lessepsian immigrant species was only known from Israeli waters where it is established but rare.
On the presently available evidence, the Maltese specimen has to be considered as a casual, most likely transported by shipping.

Rapid assessment of the marine alien megabiota in the shallow coastal waters of the Greek islands, Paros and Antiparos, Aegean Sea
(pp S133-S137)
|
|
The shallow seabed off the Greek islands Paros and Antiparos was surveyed for the presence of alien megabiota during July 2011.
Fourteen sites were surveyed by snorkeling at depths between 0 and 10 m. Eight alien species were recorded:
Caulerpa racemosa var. cylindracea, Halophila stipulacea, Pinctada radiata, Percnon gibbesi,
Cassiopea andromeda, Aplysia dactylomela, Siganus luridus and Fistularia commersonii. The first four
species are new records for the islands; all eight species established populations in the study area. Siganus luridus was
present in high numbers in all sites and may be considered as highly invasive. Cassiopea andromeda reappeared in the Aegean
Sea after a hiatus of 55 years, reaching densities >20 individuals/m2 at one site.

The reef-associating butterfly fish Chaetodon austriacus Rüppell, 1836 in the Mediterranean:
The implication of behavioral plasticity for bioinvasion hazard assessment
(pp S143-S145)
|
|
A single specimen of the blacktail butterflyfish, Chaetodon austriacus, one of the most common butterflyfishes in the Red Sea,
was collected in the port of Ashdod, on the Mediterranean coast of Israel in August 2011. The present record demonstrates a greater
than expected plasticity in habitat choice and feeding habits in a species considered an obligate corallivore. Recent records of Eritrean
coral-reef associating species in the Mediterranean serve as a warning that life-history based bioinvasion risk assessment has limited
predictability in cases where species have broader environmental tolerances than their native range would seem to indicate.

The invasive freshwater medusa Craspedacusta sowerbii Lankester, 1880 (Hydrozoa: Olindiidae) in Israel
(pp S147-S152)
|

The freshwater jellyfish Craspedacusta sowerbii, native to China, has been introduced to lentic and lotic habitats
in artificial and natural bodies of water, in subtropical to temperate regions worldwide. In the Middle East it has been
recorded from an artificial lake in the Nile Delta, Egypt, a recreational lake in Iraq, a reservoir and a dammed lake in Turkey.
The first record in Israel dates back half a century – to an aquarium at the Hebrew University in Jerusalem. Since 2003 medusae
of C. sowerbii have been observed in a perennial stream flowing into Sea of Galilee – Israel’s principal freshwater storage
and supply reservoir. The possible impacts of a substantial bloom are discussed.

First record of round goby, Neogobius melanostomus (Pallas, 1814) in the Sava River, Croatia
(pp S153-S157)
|

In June 2011, 34 specimens of round goby (Neogobius melanostomus) were caught at three different locations in the Sava River in Croatia,
which is a first record of this invasive species in Danube tributaries in Croatia. Size, structure and condition of populations indicate that
the species is well adjusted to its new habitat and that further range expansions are highly likely.
