In this paper we report on the effect that invasive algae have at the community level, targeting mainly the smaller size components (small macrofauna and meiofauna), using the 18S and the COI genes and the fractionation procedure and bioinformatic pipeline developed in our project. Here goes the abstract:
We analysed with multigene (18S and COI) metabarcoding the effects of the proliferation of invasive seaweeds on rocky littoral communities in two Spanish Marine Protected Areas. The invasive algae studied were Caulerpa cylindracea, Lophocladia lallemandii and Asparagopsis armata. They are canopy-forming, landscape-dominant seaweeds, and we were interested in their effects on the underlying communities of meiobenthos and macrobenthos, separated in two size fractions through sieving. A new semiquantitative treatment of metabarcoding data is introduced. The results for both markers showed that the presence of the invasive seaweed had a significant effect on the understory communities for Lophocladia lallemandii and Asparagopsis armata but not for Caulerpa cylindracea. Likewise, changes in MOTU richness and diversity with invasion status varied in magnitude and direction depending on the alga considered. Our results showed that metabarcoding allows monitoring of the less conspicuous, but not least important, effects of the presence of dominant invasive seaweeds.

ChallenGen at the meeting "Developing new genetic tools for bioassessment of aquatic ecosystems in Europe"
by Xavier Turon
ChallenGen was present at the meeting on metabarcoding held in Essen (Germany) in March 7th-9th 2017. This was the kick-off conference of the European Union COST action DNAqua-Net.
This project aims at integrating a group of researchers across disciplines with the task to identify gold-standard genomic tools and novel eco-genomic indices and metrics for routine application for biodiversity assessments and biomonitoring of European water bodies. It also envisages training and dissemination activities. The objectives of ChallenGen are fully compatible with the goals of DNAqua-Net and we wanted to be counted in and contribute.
Xavier Turon is one of the Spanish members of DNAqua-Net and attended this conference, where ca. 200 researchers gathered together to present results, discuss hot topics, and delineate the way forward for achieving a wide acceptance by management bodies of genetic methods for biodiversity assessment in the European context.
Xavier presented the communication "Under the canopy: community-wide effects of invasive algae in marine protected areas revealed by metabarcoding", by Xavier Turon, Owen Wangensteen, Emma Cebrian and Creu Palacín. In this contribution the main results concerning the effects of three invasive algae (Caulerpa cylindracea and Lophocladia lallemandii in Cabrera, and Asparagopsis armata in the Atlantic) on the benthic communities were exposed. We have also drafted and sent a manuscript for publication with these results. This contribution is also a result of the collaboration between ChallenGen and the National Park projects Metabarpark and Corclim.

ChallenGen Project and CEAB at the XIV Firamar
by Maria Casso
Last weekend, the 20th-21st July, the Centre for Advanced Studies of Blanes (CEAB - CSIC) participated at the XIV Firamar of Sant Pol de Mar. The Firamar is a fair of artisans and activities related to the sea, like many research projects developed at the CEAB. Our ChallenGen Project, which is developed partially at the CEAB, got involved in the event.
As a member of the ChallenGen Project and the CEAB, I stayed in our stand at the fair during Saturday afternoon, explaining the work researchers conduct at the CEAB about invasive species, climate change, conservation, ecology and biodiversity. It was really nice to see how interested are many people on our job!

New paper published: Spatio-temporal patterns of genetic diversity of Styela plicata in harbour populations
by Xavier Turon
We add another paper to the Styela plicata history: “Stochasticity in space, persistence in time: genetic heterogeneity in harbour populations of the introduced ascidian Styela plicata”, by Mari-Carmen Pineda, Beatriz Lorente, Susanna López-Legentil, Creu Palacín and Xavier Turon, which has been published today (23rd June) in PeerJ.
In this study, we analysed genetic structure of the populations of Styela plicata in 9 harbours along the Iberian Mediterranean coast and adjacent Atlantic waters (>1,200 km range) at two time points 5 years apart (2009 and 2014). Using COI sequence data of ca. 400 specimens, we found strong spatial genetic structure, with significant differences among many populations, but no significant differences among years. Our results revealed spatial genetic heterogeneity and temporal homogeneity in S. plicata, suggesting a limited role of recurrent, vessel-mediated transport of organisms among small to medium-size harbours. Our study area is representative of many highly urbanized coasts with dense harbour networks. In these environments, the episodic chance arrival of colonisers appears to determine the genetic structure of populations and the genetic composition of these early colonising individuals persists in the respective harbours, at least over moderate time frames (five years) that encompass ca. 20 generations of S. plicata.
This article is yet another instance of the importance of the temporal component in studies of introduced species to unravel processes occurring during secondary dispersal of non-indigenous species.

Monitoring ascidians in the Venetian Lagoon
by Maria Casso
The Benthic Ecology research group from the Istituto di Scienze Marina, ISMAR (Consiglio Nazionale delle Ricerche, CNR), placed in the Venetian Lagoon, is hosting me for a 3 months research stay. They focuses on ecology of coastal transitional ecosystems, specially benthic communities. More recently, they are interested on wood-boring marine organisms (shipworms and gribbles). This is very important in a place like the Venetian Lagoon as it has a large wooden maritime cultural heritage.
The aim of my stay in Venice is to study the invasive ascidians, which grow on top of those wooden marine structures. To do this, yesterday we went to a field trip around the Venetian Lagoon with Davide Tagliapietra, Marco Sigovini and Irene Guarneri. It was foggy in the beginning but more sunny at the end of the sampling. The objective of the field trip was to determine the distribution of some invasive ascidians and to collect samples for aquaria experiments.

Temporal genetic structure in the introduced ascidian Styela plicata
by M.Carmen Pineda
It’s been almost three years since the last paper on Styela plicata was published by our group, but the saga is not over yet!! The article entitled “Stable populations in unstable habitats: temporal genetic structure of the introduced ascidian Styela plicata in North Carolina”, by M.Carmen Pineda, Xavier Turon, Rocio Perez-Portela and Susanna Lopez-Legentil, has been just published online in the journal Marine Biology.
Styela plicata is a solitary ascidian, which has been introduced by ship fouling to harbours and marinas around the globe. This species has been extensively studied during the last years, based on its potential to become a plague. However, this is the first time that its genetic composition is studied on a temporal scale. On this recent study, a combination of nuclear and mitochondrial markers (7 microsatellites and a fragment of the gene Cytochrome Oxidase subunit I, COI) were used to analyse the genetic composition of one population subjected to environmental fluctuations and periodical die-offs, every 2 months and over 2.5 years. Overall, our results indicate that the investigated population is stable over time and relies on a periodic arrival of larvae from other populations, maintaining high genetic diversity and a complex interplay of allele gains and losses.
Temporal analyses exploring genetic trends over time are a great tool to predict the likelihood of long time survival of an introduced population in a new habitat and its invasive potential. This kind of information is particularly relevant when deciding which introduced species are more detrimental, and should help resource managers to focus their control and eradication efforts.

New paper published: Clavelina oblonga in the Ebro Delta
by Xavier Turon
The article “When invasion biology meets taxonomy: Clavelina oblonga (Ascidiacea) is an old invader in the Mediterranean Sea” by Víctor Ordóñez, Marta Pascual, Margarita Fernández and Xavier Turon is now published online in Biological Invasions.
In this paper we report the taxonomic status of a marine pest that has recently proliferated in bivalve cultures of the Ebro Delta, smothering mussel spat and causing concern among fishermen. The species was initially identified as Clavelina phlegraea, described in 1929 in Italy and endemic of the Mediterranean. Further morphological and genetic studies, however, have concluded that C. phlegraea is a synonym of the Atlantic species C. oblonga, which has been introduced into the Mediterranean at least 80 years ago, but was known under a different name there. This study illustrates the problems of traditional taxonomy to cope with the global-scale distribution of introduced species.
We have also monitored growth and reproductive cycles of C. oblonga in the Ebro Delta, which were markedly seasonal, with peak abundance and reproduction in summertime, followed by regression in winter. Avoidance of mussel and oyster seeding during late summer and early autumn can readily reduce the damage caused by this species.

Lectures at the Course “New Technologies applied to the control and monitoring of invasive species”
by Xavier Turon
In October, 19 to 23, the National Parks Autonomous Agency (OAPN) organised a course on new technologies applied to the study of invasive species in Vigo (Galicia). This course was attended by staff, technicians, and rangers of the National Parks in Spain.
I was invited to give a lecture about “Genetic tools and invasive species”. It was an enjoyable experience, with interested audience that posed clever questions... and of course it was an occasion to enjoy good shellfish “mariscada” typical of Galicia’s gastronomy.

Monitoring invasive ascidians at Ebro Delta
| A nice view of the bivalve culture area. |
Today we went to the Ebro Delta, for monitoring the invasive ascidians at the oyster and mussel culture structures. After a week of stormy days, we had a sunny and calm monitoring day.
We want to thank the Institute of Food and Agricultural Research and Technology (IRTA) for providing the boat and skipper and collaborate in this monitoring.

The opening of the New Suez Canal
by Enrique Macpherson
The New Suez Canal was opened on August 6th 2015. The ecological impact can be catastrophic...
In September 2014, one month after the enlargement of the Suez Canal was announced, eighteen scientists published an article in the journal Biological Invasions highlighting the threat of invasive species and calling the expansion “ominous.” The article asked for compliance with United Nations treaties that have jurisdiction over environmental issues in the Mediterranean, and to which Egypt is a signatory.
By December, two hundred concerned scientists from twenty-five countries, began a letter writing campaign to environmental groups asking for help approaching authorities to request an environmental risk assessment of the Canal expansion. We wrote, “We recognize that global trade and shipping are vital to society, however, the existing international agreements also recognize the urgent need for sustainable practices that minimize unwanted impacts and long term consequences.”
A single Member of the European Parliament, Ricardo Serrão Santos of Portugal, introduced a statement about the canal on the floor of the Parliament. He said, "I would like to draw your attention to the enlargement of the Suez Canal. This process will increase marine pollution, including more alien species. The expected impact goes far beyond the proposing country and will have implications across the Mediterranean Sea, as indeed has the actual Suez Canal. For this reason I call for a proper environmental impact study that is holistic, comprehensive, deep, international and, more important, consequential." No further action was taken by the Parliament.
Of the dozens of environmental groups who received the letter, only the International Union for Conservation of Nature (IUCN) responded. They wrote to the Directorate-General of the European Commission suggesting mitigation measures and offering technical assistance. “Effective solutions do exist, for example the creation of an environmental barrier to biological invasions using naturally occurring highly saline Bitter Lakes (these lakes reduced the introduction of Red Sea species into the Mediterranean for many decades).” By February, the letter authored by the concerned scientists collected five hundred signatures from forty countries. Still, the international community remained mute.
No response ever came from any group charged with environmental oversight of the Mediterranean. No environmental risk assessment was ever performed. This willful myopia by the bodies whose mission is to protect the sea is putting the Mediterranean at grave risk.

New paper published: Corridors for aliens but not for natives: effects of marine urban sprawl at a regional scale
"Marine urban sprawl creates corridors for invasives
It is well established that corridors can, in certain cases, help spread non-native species in terrestrial ecosystems. In a new study by Airoldi et al., the authors expand on this theme with a look at the spread of non-native species at a regional scale. This study compares artificial marine infrastructure (ex. harbors, dikes, piers, breakwaters, etc.) and natural reefs. Their extensive look at 500 kilometers of shoreline in the North Adriatic Sea provides clues as to how marine corridors contribute to the spread of native and non-native species alike."
