Abstract

Invasive species pose serious threats to ecosystems. To reduce ecological and economic consequences of invasions, efforts are made to control invaders and evaluating the effects of such efforts is paramount. Lionfishes (Pterois volitans and Pterois miles) are native to the Indo-Pacific Ocean and pose a major threat to local ecosystems in the invaded Atlantic and Mediterranean. Culling via spearfishing is a widespread measure to limit lionfish population size in invaded ranges. However, like most hunted fishes, lionfish alter their behavior after repeated culling, potentially decreasing the effectiveness of future culls. Previous studies on lionfish in the Caribbean have shown that lionfish are less bold after repeated culling. However, the impact of culling on lionfish in their newest invasive range, the Mediterranean, remains enigmatic. To determine the behavioral changes in response to culling in this second area of invasion, we tested for effects of culling on the behavior of lionfish in Cyprus, a region heavily impacted by the lionfish invasion in the Mediterranean. We compared the response of lionfish to an approaching free diver holding a metal pole (imitating a spear fisher) between protected areas where spearfishing is restricted and areas where culls are frequently conducted. We also assessed whether activity, hiding pattern, and site fidelity differed between these culled and unculled sites. Overall, we found limited effects of culling on the traits measured, indicating surprising resistance to culling-induced behavioral changes in Mediterranean lionfish. Future studies should monitor invasive lionfish population densities and the effects of culling in more detail to tailor management plans and reduce the negative effects of these fish in specific invaded ranges.

Abstract

Marine protected areas (MPAs) can protect and restore marine biodiversity and fisheries, but there are concerns that they may also benefit invasive species. The spatial and temporal colonization of invasive lionfish (Pterois miles) in the eastern Mediterranean was compared across zones with varying fishing restrictions (no fishing, recreational and commercial fishing, and commercial fishing only), and stations where targeted removal events were conducted by volunteer SCUBA divers. Lionfish density in no fishing areas was nearly double that of areas with commercial fishing only, and over four times greater than in areas where both commercial and recreational fishing were allowed. Lionfish density increased with depth, possibly due to easier human exploitation in shallow waters (0–10 m) that are accessible to recreational spearfishers. Targeted removals by volunteer divers decreased lionfish densities by over 60%, while areas without removals had a 200%–400% increase. Along with management actions, natural and ecological processes might drive lionfish densities within MPAs, and the speed with which lionfish colonized fishery‐restricted zones, emphasized the need for a more sophisticated MPA management strategy that considers invasive species impacts and dynamics in an ecosystem‐based approach.

Abstract

To enrich spatio-temporal information on the distribution of alien, cryptogenic, and neonative species in the Mediterranean and the Black Sea, a collective effort by 173 marine scientists was made to provide unpublished records and make them open access to the scientific community. Through this effort, we collected and harmonized a dataset of 12,649 records. It includes 247 taxa, of which 217 are Animalia, 25 Plantae and 5 Chromista, from 23 countries surrounding the Mediterranean and the Black Sea. Chordata was the most abundant taxonomic group, followed by Arthropoda, Mollusca, and Annelida. In terms of species records, Siganus luridus, Siganus rivulatus, Saurida lessepsianus, Pterois miles, Upeneus moluccensis, Charybdis (Archias) longicollis, and Caulerpa cylindracea were the most numerous. The temporal distribution of the records ranges from 1973 to 2022, with 44% of the records in 2020–2021. Lethrinus borbonicus is reported for the first time in the Mediterranean Sea, while Pomatoschistus quagga, Caulerpa cylindracea, Grateloupia turuturu, and Misophria pallida are first records for the Black Sea; Kapraunia schneideri is recorded for the second time in the Mediterranean and for the first time in Israel; Prionospio depauperata and Pseudonereis anomala are reported for the first time from the Sea of Marmara. Many first country records are also included, namely: Amathia verticillata (Montenegro), Ampithoe valida (Italy), Antithamnion amphigeneum (Greece), Clavelina oblonga (Tunisia and Slovenia), Dendostrea cf. folium (Syria), Epinephelus fasciatus (Tunisia), Ganonema farinosum (Montenegro), Macrorhynchia philippina (Tunisia), Marenzelleria neglecta (Romania), Paratapes textilis (Tunisia), and Botrylloides diegensis (Tunisia).

Abstract

The tendency of world media to villainize of sharks has likely contributed to a disparity in the distribution of research and conservation resources among threatened marine megavertebrates, with elasmobranchs losing out. Increased public knowledge on elasmobranchs can shape public attitude and foster and gain support for elasmobranch conservation. Through an online survey, this study aimed to evaluate the drivers of public knowledge and examine linkages between awareness of elasmobranchs and attitude toward their conservation. To explore the relationships and effects between the different predicting variables and public elasmobranch knowledge and attitude indices, bi- and multi-variate analysis and a partial least squares path model were used. The results indicated that the average public elasmobranch knowledge of the Cypriot population was moderate and the average public attitude towards elasmobranchs was relatively low. Marine-related activities and marine-related education were highly correlated with increased public elasmobranch knowledge and were the strongest predictors of the partial least squares path model which explained a high degree of variation in elasmobranch knowledge. Public elasmobranch knowledge was highly correlated with public attitude towards elasmobranchs. The findings of this study highlighted the importance of ocean literacy and education and provide insights into the mechanisms for developing and designing successful advocacy actions for elasmobranch conservation.

Abstract

Depredation by cetaceans on fisheries is a major issue globally, both in terms of conservation and fisheries economics. The present study conducted in Cyprus, Eastern Mediterranean Sea, aimed to understand the extent, level, and type of cetacean depredation on the albacore tuna pelagic longline fishery, and in particular to quantify and evaluate the economic consequences of depredation and identify potential dolphin-longline conflict areas and mitigation practices for management. The data were obtained from fisher’s logbooks, interviews and onboard observations between June and August 2018. A novel and simple approach was applied to estimate the depredation rate and economic loss by using simple calculations including the number and weight of depredated fish, landings and fishing effort. The results revealed that there is an estimated economic loss per fishing trip of 313.07± 486.19 EUR and an estimated annual economic loss for the entire fleet of 259,272 EUR from depredation caused by cetaceans. The study also estimated that 16,639 albacore tunas were depredated in 2018 and the depredation rate ranged between 0% to 100% with a mean depredation rate of 17% per fishing trip. Depredation by the common bottlenose dolphin and striped dolphin was reported in more than 50% of their fishing trips. Other species that were found to be involved in depredation were the neon flying squid, the shortfin mako shark and the Risso’s dolphin. This is the first official record worldwide of depredation from the common bottlenose dolphin, the striped dolphin and the neon flying squid on the pelagic longline albacore tuna fishery. A total bycatch of 62 individuals of common bottlenose dolphins and one individual of stripped dolphin were reported in interviews as a result of depredation on bait and catch. The study also identified depredation hotspots and possible depredation mitigation measures. Such information could support the development of management action plans and measures to minimise interactions between cetaceans and pelagic longlines.

Abstract

We analysed the patterns of genetic variabilityof eastern Mediterranean populations of the scleractinian coral Cladocora caespitosa, from the Aegean and Levan-tine seas, using 19 polymorphic microsatellite loci, 11 ofwhich were newly characterized. The observed genetic pattern reflects a scenario of isolation by environment: FST comparisons showed a higher degree of genetic differentiation between the two Cypriot populations that are separated by only 11 km than between these two Levantine populations and the Aegean population in Greece, whichare separated by 1300 km. We hypothesize that local-scale oceanographic factors influenced the dispersal of planulae between the geographically close populations, playing acrucial role in the genetic structure of this coastal coral.Yet, despite being characterized as a species with limited dispersal and high self-recruitment, large-scale migrationdoes eventually occur as first-generation migrants wereidentified between the most distant populations. In linewith previous findings of reproductive plasticity in C.caespitosa, we also found localized differences in reproduction mode (sexual vs. asexual) within a geographically limited context. Several individuals were identified asclones, indicating the predominance of asexual reproduction in one of the Cypriot populations. We interpret this predominance either as a direct response to or as an indirectconsequence of perturbations suffered by thisC. caespitosapopulation. These perturbations are caused by unfavourable environmental conditions that threatened local sur-vival, in particular water temperature changes andwindstorm swells. Asexual reproduction may be a mecha-nism used byC. caespitosato counteract mortality eventsand recolonize devastated areas, and likely accounts for the occasional high levels of clonality and low levels of genetic diversity. Local adaptations such as these should thereforebe considered in conservation and management strategiesto maintain and preserve the gene pool of this endangered species. This research was funded by the Spanish Ministry of Economy and Competitiveness (Grant reference: CTM2014-57949-R) and the Spanish Ministry of Science and Innovation (Grantreference: PID2019-108644 GB-I00). ENALIA’s research programand Nephila Works Ltd. also provided financial support.

Abstract

Good datasets of geo-referenced records of alien species are a prerequisite for assessing the spatio-temporal dynamics of biological invasions, their invasive potential, and the magnitude of their impacts. However, with the exception of first records on a country level or wider regions, observations of species presence tend to remain unpublished, buried in scattered repositories or in the personal databases of experts. Through an initiative to collect, harmonize and make such unpublished data for marine alien and cryptogenic species in the Mediterranean Sea available, a large dataset comprising 5376 records was created. It includes records of 239 alien or cryptogenic taxa (192 Animalia, 24 Plantae, 23 Chromista) from 19 countries surrounding the Mediterranean Sea. In terms of records, the most reported Phyla in descending order were Chordata, Mollusca, Chlorophyta, Arthropoda, and Rhodophyta. The most recorded species was Caulerpa cylindracea, followed by Siganus luridus, Magallana sp. (cf. gigas or angulata) and Pterois miles. The dataset includes records from 1972 to 2020, with the highest number of records observed in 2018. Among the records of the dataset, Dictyota acutiloba is a first record for the Mediterranean Sea. Nine first country records are also included: the alga Caulerpa taxifolia var. distichophylla, the cube boxfish Ostracion cubicus, and the cleaner shrimp Urocaridella pulchella from Israel; the sponge Paraleucilla magna from Libya and Slovenia; the lumpfish Cyclopterus lumpus from Cyprus; the bryozoan Celleporaria vermiformis and the polychaetes Prionospio depauperata and Notomastus aberans from Malta.

Abstract

Invasive alien species (IAS) are known to be a major threat to biodiversity and ecosystem function and there is increasing evidence of their impacts on human health and economies globally. We undertook horizon scanning using expert-elicitation to predict arrivals of IAS that could have adverse human health or economic impacts on the island of Cyprus. Three hundred and twenty five IAS comprising 89 plants, 37 freshwater animals, 61 terrestrial invertebrates, 93 terrestrial vertebrates, and 45 marine species, were assessed during a two-day workshop involving 39 participants to derive two ranked lists: (1) IAS with potential human health impacts (20 species ranked within two bands: 1–10 species or 11–20 species); and, (2) IAS with potential economic impacts (50 species ranked in three bands of 1–10, 11–20, and 21–50). Five species of mosquitoes (Aedes aegypti, Aedes albopictus, Aedes flavopictus, Aedes japonicus, and Culex quinquefasciatus) were considered a potential threat to both human health and economies. It was evident that the IAS identified through this process could potentially arrive through many pathways (25 and 23 pathways were noted for the top 20 IAS on the human health and economic impact lists respectively). The Convention on Biological Diversity Level II (subcategory) pathways Contaminant on plants, pet/aquarium/terrarium species (including live food for such species), hitchhikers in or on aeroplanes, hitchhikers in or on ship/boats, and vehicles were the main pathways that arose across both lists. We discuss the potential of horizon scanning lists to inform biosecurity policies and communication around IAS, highlighting the importance of increasing understanding amongst all stakeholders, including the public, to reduce the risks associated with predicted IAS arrivals.

Abstract

Good datasets of geo-referenced records of alien species are a prerequisite for assessing the spatio-temporal dynamics of biological invasions, their invasive potential, and the magnitude of their impacts. However, with the exception of first records on a country level or wider regions, observations of species presence tend to remain unpublished, buried in scattered repositories or in the personal databases of experts. Through an initiative to collect, harmonize and make such unpublished data for marine alien and cryptogenic species in the Mediterranean Sea available, a large dataset comprising 5376 records was created. It includes records of 239 alien or cryptogenic taxa (192 Animalia, 24 Plantae, 23 Chromista) from 19 countries surrounding the Mediterranean Sea. In terms of records, the most reported Phyla in descending order were Chordata, Mollusca, Chlorophyta, Arthropoda, and Rhodophyta. The most recorded species was Caulerpa cylindracea, followed by Siganus luridus, Magallana sp. (cf. gigas or angulata) and Pterois miles. The dataset includes records from 1972 to 2020, with the highest number of records observed in 2018. Among the records of the dataset, Dictyota acutiloba is a first record for the Mediterranean Sea. Nine first country records are also included: the alga Caulerpa taxifolia var. distichophylla, the cube boxfish Ostracion cubicus, and the cleaner shrimp Urocaridella pulchella from Israel; the sponge Paraleucilla magna from Libya and Slovenia; the lumpfish Cyclopterus lumpus from Cyprus; the bryozoan Celleporaria vermiformis and the polychaetes Prionospio depauperata and Notomastus aberans from Malta.

Η παρούσα διατριβή διερευνά τις οικολογικές και βιολογικές αποκρίσεις του μεσογειακού κοραλλιού Cladocora caespitosa, σε περιβαλλοντικές αλλαγές. Το σκληρακτήνιο αυτό είδος κοραλλιού, το οποίο χτίζει αποικίες, έχει ανομοιότυπη κατανομή κατά μήκος της Μεσογείου και παρουσιάζει σχετικά μεγάλους πληθυσμούς και στην Κύπρο. Μελετήσαμε πληθυσμούς που βρίσκονται σε αφθονία σε δύο περιοχές στη νοτιοανατολική ακτή της Κύπρου, στην περιοχή ΄Κρυό Νερό’, όπου καταγράφονται λιγότερα θρεπτικά συστατικά, και στην περιοχή ‘Λιοπέτρι’, η οποία είναι πιο πλούσια σε θρεπτικά λόγω ανθρωπογενών δραστηριοτήτων.Μέσω της συστηματικής παρακολούθησης των αποικιών στους θερμότερους μήνες των 2014 και 2015, καταγράψαμε την εκδήλωση θνησιμότητας που είχε ως αποτέλεσμα την απώλεια του «χρωματισμένου ιστού» και την αύξηση των πρόσφατων «νεκρωτικών» περιοχών σε κοράλλια και στις δύο περιοχές μελέτης. Η θνησιμότητα των κοραλλιών ήταν σημαντικά μεγαλύτερη το 2015, κάτι που συμπίπτει με παρατεταμένες περόδους υψηλών θερμοκρασιών (>29 οC). Παρατηρήθηκαν σημαντικές διαφορές μεταξύ των περιοχών οι οποίες αποδίδονται κυρίως στις αυξημένες συγκεντρώσεις θρεπτικών ουσιών στη μία από τις περιοχές. Επιπλέον, κατά τη διάρκεια μιας ακραίας χειμερινής ανεμοθύελλας, το 7% των αποικιών στο ‘Κρυό Νερό’ έχασε κατά μέσο όρο το 50% των «χρωματισμένων ιστών» εξαιτίας των κυμάτων που προκάλεσε η καταιγίδα, τα οποία χτυπώντας στα βράχια ώθησαν μεγάλους ογκόλιθους να καταρρεύσουν, με αποτέλεσμα να πέσουν πάνω στις αποικίες. Οι ρυθμοί ανάπτυξης (~2,9 mm/έτος) των κοραλλιών στην Κύπρο βρέθηκαν να είναι παρόμοιοι με αυτούς της δυτικής Μεσογείου. Πειράματα ‘κοινού περιβάλλοντος’ έδειξαν οτι τα κοράλλια που συλλέχθηκαν από την περιοχή με λιγότερα θρεπτικά και μεταμοσχεύθηκαν στην περιοχή με περισσότερα θρεπτικά είχαν, τουλάχιστον βραχυπρόθεσμα, πολύ μεγαλύτερους ρυθμούς αύξησης (~6,2 mm/έτος). Υποθέτουμε ότι αυτό οφείλεται στις συνθήκες αυξημένων θρεπτικών συστατικών. Αξιολογήσαμε τη σεξουαλική κατάσταση και τον αναπαραγωγικό κύκλο των C. caespitosa από την Κύπρο, λαμβάνοντας υπόψη κάποιες περιβαλλοντικές παραμέτρους (θερμοκρασία επιφάνειας θάλασσας και επιφανειακή πρωτογενή παραγωγή) και τις συγκρίναμε με αυτές από τη δυτική Μεσόγειο και την Αδριατική. Προσδιορίσαμε τις αποικίες των C. caespitosa ως γονοχωριστικές, με την ωοτοκία να λαμβάνει χώρα στα τέλη του καλοκαιριού, όπως και εκείνες από τη δυτική Μεσόγειο, αλλά σε αντίθεση με εκείνες της Αδριατικής, οι οποίες έχουν περιγραφεί ως ερμαφρόδιτες, η ωοτοκία των οποίων λαμβάνει χώρα στην αρχή του καλοκαιριού. Διαπιστώσαμε ότι η θερμοκρασία είναι σημαντικός παράγοντας για την ανάπτυξη των γαμετών και της επαγωγής της αναπαραγωγής αλλά δεν εντοπίσαμε σημαντικότητα σε σχέση με την πρωτογενή παραγωγή. Συλλέξαμε ζωντανά δείγματα κοραλλιών από τις αποικίες και των δύο περιοχών, τα οποία διατηρήσαμε σε ενυδρεία κάτω από συνθήκες θρεπτικών ίδιες με εκείνες στις περιοχές συλλογής. Ακολούθως, εκθέσαμε τα κοράλλια σε σταδιακά αυξημένες θερμοκρασίες προκειμένου να διερευνηθεί ο ρόλος του ιστορικού των θρεπτικών στοιχείων στην επίδραση της απόκρισης των κοραλλιών C. caespitosa σε θερμικό στρες. Τα κοράλλια που αναπτύχθηκαν σε συνθήκες φτωχών συνθηκών σε θρεπτικά υπέστησαν λεύκανση και μειώθηκε σημαντικά η περιεκτικότητά τους σε πρωτεΐνες, καθώς επίσης και οι ρυθμοί της φωτοσύνθεσής τους. Αντίθετα, οι αποικίες που αναπτύχθηκαν σε πλούσια θρεπτικά δεν παρουσίασαν σημάδι λεύκανσης ή αλλαγή στον συνολικό μεταβολισμό τους. Τα αποτελέσματά μας δείχνουν ότι το ιστορικό των θρεπτικών ουσιών στο περιβάλλον μπορεί να επηρεάσει την απόκριση των σκληρακτίνιων κοραλλιών υπό θερμικό στρές. Επιπλέον, τα αποτελέσματά μας υποδηλώνουν ότι τα κοράλλια που ευδοκιμούν σε περιβάλλοντα πλούσια σε θρεπτικά είναι πιθανόν εκείνα με υψηλή ετεροτροφική ικανότητα. The present thesis explores the ecological and biological responses to environmental changes in the Mediterranean coral Cladocora caespitosa in Cyprus. This colonial scleractinian coral species has a patchy distribution along the Mediterranean Sea and holds relatively large populations in Cyprus. We studied colonies at two areas situated in the southeast of Cyprus that hold an abundance of C. caespitosa colonies, a naturally low-nutrient site (Kryo Nero) and an anthropogenically impacted high-nutrient site (Liopetri).Through systematic monitoring of colonies in the warmest months of 2014 and 2015, we observed a mortality event that resulted in the decline of ‘Pigmented tissue’ and an increase of ‘Recently necrotic’ areas in corals at both study sites. Coral deterioration was significantly more in 2015, associated with prolonged periods of high temperatures (>29 oC). Differences in effect were observed between the sites and attributed mainly to the elevated nutrient concentrations. In addition, during an extreme winter windstorm, 7% of the colonies at Kryo Nero lost an average of 50% of pigmented tissue due to storm-generated waves, which forced boulders to collapse on top of them. We measured growth rates (~2.9 mm/yr) to be similar as in the Western Mediterranean. Interestingly, common garden experiments showed that corals collected from the low-nutrient site and transplanted in the high-nutrient had, at least in the short term, much larger growth rates (6.2 mm per year) assumingly due to the elevated nutrient conditions. We assessed the sexual condition and reproductive cycle of C. caespitosa from Cyprus considering some environmental parameters (sea surface temperature and surface primary production) and compared them with the ones from Western Mediterranean and Adriatic Sea. We identified colonies of C. caespitosa in Cyprus to be gonochoric, with spawning occurring at the end of the summer, much like the ones from Western Mediterranean, but in contrast to the ones from the Adriatic, which have been described as hermaphroditic that spawn at the beginning of the Summer. We found temperature to be an important driving factor for gamete development and spawning, but no association with primary production had been detected. We collected samples of colonies from both sites (Low-nutrient vs high-nutrient), maintained under the right nutrient conditions in aquaria and exposed to temperature increase in order to investigate the role of the nutrient history in influencing the response of Cladocora caespitosa to thermal stress. Colonies grown in nutrient-poor conditions bleached and significantly decreased their protein content and rates of net photosynthesis. On the contrary, colonies grown under nutrient enrichment presented no sign of bleaching and no change in their overall metabolism. Our results show how nutrient history can influence the response of scleractinian corals to thermal stress. In addition, they suggest that corals with a high success in nutrient rich environments are likely those with a high heterotrophic capacity.

Abstract

A mass mortality event is devastating the populations of the endemic bivalve Pinna nobilis in the Mediterranean Sea from early autumn 2016. A newly described Haplosporidian endoparasite (Haplosporidium pinnae) is the most probable cause of this ecological catastrophe placing one of the largest bivalves of the world on the brink of extinction. As a pivotal step towards Pinna nobilis conservation, this contribution combines scientists and citizens’ data to address the fast- and vast-dispersion and prevalence outbreaks of the pathogen. Therefore, the potential role of currents on parasite expansion was addressed by means of drift simulations of virtual particles in a high-resolution regional currents model. A generalized additive model was implemented to test if environmental factors could modulate the infection of Pinna nobilis populations. The results strongly suggest that the parasite has probably dispersed regionally by surface currents, and that the disease expression seems to be closely related to temperatures above 13.5 °C and to a salinity range between 36.5–39.7 psu. The most likely spread of the disease along the Mediterranean basin associated with scattered survival spots and very few survivors (potentially resistant individuals), point to a challenging scenario for conservation of the emblematic Pinna nobilis, which will require fast and strategic management measures and should make use of the essential role citizen science projects can play.

Abstract

The criteria for species delimitation in birds have long been debated, and several recent studies have proposed new methods for such delimitation. On one side, there is a large consensus of investigators who believe that the only evidence that can be used to delimit species is molecular phylogenetics, and with increasing numbers of markers to gain better support, whereas on the other, there are investigators adopting alternative approaches based largely on phenotypic differences, including in morphology and communication signals. Yet, these methods have little to say about rapid differentiation in specific traits shown to be important in reproductive isolation. Here, we examine variation in phenotypic (morphology, plumage, and song) and genotypic (mitochondrial and nuclear DNA) traits among populations of yellow‐rumped tinkerbird Pogoniulus bilineatus in East Africa. Strikingly, song divergence between the P. b. fischeri subspecies from Kenya and Zanzibar and P. b. bilineatus from Tanzania is discordant with genetic distance, having occurred over a short time frame, and playback experiments show that adjacent populations of P. b. bilineatus and P. b. fischeri do not recognize one another's songs. While such rapid divergence might suggest a founder effect following invasion of Zanzibar, molecular evidence suggests otherwise, with insular P. b. fischeri nested within mainland P. b. fischeri. Populations from the Eastern Arc Mountains are genetically more distant, yet share the same song with P. b. bilineatus from Coastal Tanzania and Southern Africa, suggesting they would interbreed. We believe investigators ought to examine potentially rapid divergence in traits important in species recognition and sexual selection when delimiting species, rather than relying entirely on arbitrary quantitative characters or molecular markers. 8 1 716 731
