  • 1 October 2003
Fish length correlated with both the total intensity of parasites and species richness among infracommunities and mean total intensity across the fish samples, indicating that the characteristics of parasite assemblages in a fish population are strongly influenced by the size of its fish in relation to those in other populations.

Corynosoma australe Johnston, 1937 and C. cetaceum Johnston & Best, 1942 (Acanthocephala: Polymorphidae) from marine mammals and fishes in Argentinian waters: allozyme markers and taxonomic status
A high level of genetic differentiation between the two taxa was found, suggesting a generic distinction between theTwo species, C. australe and C. cetaceum. Expand
Parasite communities in three sympatric flounder species (Pleuronectiformes: Paralichthyidae)
Similar ecological filters produce analogous infections across host species driving towards homogeneous parasite communities in sympatric paralichthyids from Argentine waters. Expand

The use of parasites as biological tags in population studies of marine fish in the south-western Atlantic has proved to be a successful tool for discriminating stocks for all species to which it hasExpand
Larvae and adults of Hysterothylacium aduncum (Rudolphi, 1802) (Nematoda: Anisakidae) in fishes and crustaceans in the south west Atlantic.
Parasitic prevalence, mean intensity and range were calculated in relation to different geographic zones, from the Argentinean-Uruguayan Common Fishing Zone to Patagonic areas and an increase of parasitism from the northern areas southwards was observed. Expand
Genetic and morphological evidence reveals the existence of a new family, genus and species of Echinorhynchida (Acanthocephala).
Gymnorhadinorhynchus gen. n. is proposed to accommodate its type species, G. decapteri sp. n., a parasite of the marine fish Decapterus punctatus (Cuvier), caught from the coastal waters of Brazil.Expand
Causes of inter-individual variation in reproductive strategies of the parasitic nematode Graphidioides subterraneus
Resource availability does not appear to constrain reproduction in G. subterraneus, with its host providing a stable, predictable environment, and results suggest that resource supply to individual worms is not limited by host size or by the number of conspecific parasites vying for the same resources.

A new species of Dichelyne (Nematoda, Cucullanidae) parasitizing sciaenid fishes from off the South American Atlantic coast
A new nematode species Dichelyne (Cucullanellus) sciaenidicola sp. nov. is described based on specimens collected from the Whitemouth croaker Micropogonias furnieri (Desmarest) and the ArgentineExpand
Parasites of Argentine anchovy in the south‐west Atlantic: latitudinal patterns and their use for discrimination of host populations
Four stocks of Argentine anchovy Engraulis anchoita in the south-west Atlantic, south of 34°S were identified by the use of parasites as biological tags, and Autumn samples were characterized by low values of prevalence for most parasite species. Expand
Genetic evidence for two sibling species within Contracaecum ogmorhini Johnston & Mawson, 1941 (Nematoda: Anisakidae) from otariid seals of boreal and austral regions
Genetic variation of Contracaecum ogmorhini (sensu lato) populations from different otariid seals of the northern and southern hemisphere was studied on the basis of 18 enzyme loci as well asExpand
