molecular identification of hysterothylacium aduncum specimens isolated from commercially important fish species of eastern mediterranean sea using mtdna cox1 and its rdna gene sequences. | the presence of a raphidascarid parasitic nematode hysterothylacium aduncum (rudolphi, 1802) in two sparid fish (sparus aurata and diplodus vulgaris) and one soleid fish (solea solea) was investigated in this study. a total of 868 individuals; 385 s. aurata, 437 d. vulgaris and 46 s. solea were collected from the mersin bay between february 2013 and january 2014 and examined. variations in the prevalence, mean intensity, and mean abundance of the parasite were 14.55%, 2.05, and 0.30 for s. aurat ... | 2015 | 25543079 |
life-history- and ecosystem-driven variation in composition and residence pattern of seabream species (perciformes: sparidae) in two mediterranean coastal lagoons. | species composition and length-frequency distributions of six sparid fish species were investigated in two central mediterranean coastal lagoons off the western coast of italy: fogliano and caprolace. in the former, the sparid fauna was dominated by the gilt-head seabream (sparus aurata), whereas in caprolace, species composition was more homogeneous across all six species. size structure varied considerably among species: s. aurata, diplodus puntazzo and diplodus vulgaris had a single-cohort st ... | 2006 | 16266729 |
evaluating the effects of protection on fish predators and sea urchins in shallow artificial rocky habitats: a case study in the northern adriatic sea. | man-made defence structures (e.g., breakwaters, jetties) are becoming common features of marine coastal landscapes all around the world. the ecology of assemblages of species associated with such artificial structures is, however, poorly known. in this study, we evaluated the density and size of fish predators of echinoids (i.e., diplodus sargus, diplodus vulgaris, sparus aurata), and the density of sea urchins (i.e., paracentrotus lividus) at defence structures (i.e., breakwaters) inside and ou ... | 2005 | 15589985 |
patterns of fish connectivity between a marine protected area and surrounding fished areas. | patterns of connectivity and self-recruitment are recognized as key factors shaping the dynamics of marine populations. connectivity is also essential for maintaining and restoring natural ecological processes with genetic diversity contributing to the adaptation and persistence of any species in the face of global disturbances. estimates of connectivity are crucial to inform the design of both marine protected areas (mpas) and mpa networks. among several approaches, genetic structure is frequen ... | 2016 | 27907100 |

potential health hazard assessment in terms of some heavy metals determined in demersal fishes caught in eastern aegean sea. | a heavy metal risk assessment based on estimated daily intake (edi) and target hazard quotient was made for children and adults. five fish species captured from the eastern aegean sea were analyzed for cr, cu, cd, hg and pb by inductively coupled plasma spectroscopy in muscle tissue of red mullet (mullus barbatus), surmullet (mullus surmuletus), sand steenbras (lithognathus mormyrus), common two-banded seabream (diplodus vulgaris) and common pandora (pagellus erythinus). the ranges for mean meta ... | 2015 | 26109309 |
establishment of a coastal fish in the azores: recent colonisation or sudden expansion of an ancient relict population? | the processes and timescales associated with ocean-wide changes in the distribution of marine species have intrigued biologists since darwin's earliest insights into biogeography. the azores, a mid-atlantic volcanic archipelago located >1000 km off the european continental shelf, offers ideal opportunities to investigate phylogeographic colonisation scenarios. the benthopelagic sparid fish known as the common two-banded seabream (diplodus vulgaris) is now relatively common along the coastline of ... | 2015 | 26174025 |

relationships among predatory fish, sea urchins and barrens in mediterranean rocky reefs across a latitudinal gradient. | previous studies conducted on a local scale emphasised the potential of trophic cascades in mediterranean rocky reefs (involving predatory fish, sea urchins and macroalgae) in affecting the transition between benthic communities dominated by erected macroalgae and barrens (i.e., bare rock with partial cover of encrusting algae). distribution patterns of fish predators of sea urchins (diplodus sargus sargus, diplodus vulgaris, coris julis and thalassoma pavo), sea urchins (paracentrotus lividus a ... | 2007 | 17034843 |
shape changes and growth trajectories in the early stages of three species of the genus diplodus (perciformes, sparidae). | the larvae of three species of the genus diplodus (diplodus vulgaris, d. sargus, and d. puntazzo) colonize shallow waters along the mediterranean coasts and, after a short period spent in the water column, they settle. for all three species this habitat transition is characterized by important shape changes mostly related to swimming capacity and feeding behavior. in this study, geometric morphometrics are used to characterize shape changes during the early juvenile life of specimens collected i ... | 2001 | 11599013 |
abundance/host size relationship in a fish trematode community. | the abundance of six species of trematodes: aphanurus stossichi, bacciger israelensis, diphterostomum israelense, plagioporus idoneus, leprocreadium album and l. pegorchis, parasitic in the digestive tract of marine teleostei (sparidae) collected near jounieh (east mediterranean), was analysed as a function of the host-size. in two parasite/host systems, infections were observed from the lowest size classes of the sample, with a clear tendency to an increase of abundance in older fish. in four o ... | 1992 | 1452993 |

assessing food web dynamics and relative importance of organic matter sources for fish species in two portuguese estuaries: a stable isotope approach. | stable carbon and nitrogen isotopes (δ¹³c, δ¹⁵n) were used to analyse food web dynamics of two of the main estuaries of the portuguese coast: tejo and mira. the ultimate sources of organic matter supporting production of some of the most abundant and commercially important fish species were determined; and seasonal, inter- and intra- estuarine differences in the trophic relations among producers and consumers were identified. stable isotope analysis was performed in different producers, primary ... | 2011 | 21958908 |
site influence in parasite distribution from fishes of the bonifacio strait marine reserve (corsica island, mediterranean sea). | the spatial distribution of parasite communities from teleost fishes (diplodus vulgaris, mullus surmuletus, pagellus erythrinus, phycis phycis, scorpaena scrofa and symphodus tinca) was studied in the bonifacio strait marine reserve (corsica island) with different protection levels. canonical correspondence analysis was used to study spatial patterns and to quantify the importance of site influence on parasite communities. to supplement these results, we used the indicator species analysis (indv ... | 2009 | 19132390 |
