| molecular identification of anisakis species from pleuronectiformes off the portuguese coast. | anisakid nematodes belonging to the anisakis simplex complex are highly prevalent in several fish species off the coast of portugal and are an important zoonotic problem in the iberian peninsula. two reproductively isolated sibling species of the anisakis simplex complex were identified from pleuronectiformes inhabiting the portuguese coast using restriction fragment length polymorphism (rflp). recombinant genotypes corresponding to presumptive anisakis simplex sensu stricto and anisakis pegreff ... | 2006 | 16469172 |
| aggregation patterns of macroendoparasites in phylogenetically related fish hosts. | summary: macroparasites are generally aggregated within their hosts with infection and aggregation levels resulting from a continuous arms race between maintaining high mating probability and host mortality low for which host and environmentally related factors contribute to some extent. here, infection and aggregation patterns of the macroendoparasites infecting the flatfish citharus linguatula, arnoglossus laterna, lepidorhombus boscii, scophthalmus rhombus and platichthys flesus in 3 areas al ... | 2010 | 20500921 |
| trophodynamic linkage between river runoff and coastal fishery yield elucidated by stable isotope data in the gulf of lions (nw mediterranean). | the link between climate-driven river runoff and sole fishery yields observed in the gulf of lions (nw mediterranean) was analysed using carbon- and nitrogen stable isotopes along the flatfish food webs. off the rhone river, the main terrestrial (river pom) and marine (seawater pom) sources of carbon differed in delta(13)c (-26.11 per thousand and -22.36 per thousand, respectively). surface sediment and suspended pom in plume water exhibited low delta(13)c (-24.38 per thousand and -24.70 per tho ... | 2004 | 14689296 |
| redescriptions of two frequently recorded but poorly known hemiurid digeneans, lecithochirium musculus (looss, 1907) (lecithochiriinae) and ectenurus lepidus looss, 1907 (dinurinae), based on material from the western mediterranean. | two frequently reported but poorly known hemiurid digeneans, lecithochirium musculus (looss, 1907) (lecithochiriinae), from the stomach of trachinus draco and citharus linguatula, and ectenurus lepidus looss, 1907 (dinurinae), from the stomach of spicara maena, are redescribed based on material from off the barcelona coast of the western mediterranean. the two species are commented upon, and lecithochirium israelense fischthal, 1980 is considered a synonym of l. musculus. records of the two spec ... | 2012 | 22711508 |
| a study on the distribution of bothriocephalus andresi (cestoda, pseudophyllidea) in citharus linguatula. | the distribution of bothriocephalus andresi (porta, 1911) in a population of citharus linguatula (l.) caught off the tuscan coasts was studied for one year. the negative binomial model proved useful for analysing the distribution of the parasite (b. andresi) in the host population. the ability of the parasite to adjust not only to its own environment but also to that of its host was clear, as it may be evinced from the greater amount of eggs and, hence, of larvae noticed in the period when there ... | 1996 | 9257340 |
