Feeding ecology of the loggerhead turtle Caretta caretta in the western Mediterranean
TLDR
Observations support the existence of an intermediate neritic phase in loggerheads' developmental shift from pelagic–oceanic to benthic–neritic foraging habitats, as previously suggested.
Insight into the role of cetaceans in the life cycle of the tetraphyllideans (Platyhelminthes: Cestoda).
TLDR
It seems clear that cetaceans act as natural intermediate hosts for P. delphini and M. grimaldii, as within these hosts they undergo development from the plerocercoid stage to the merocer coid stage, and cetACEans play a significant role in the life cycle of these larvae.
Dolphin Morbillivirus Epizootic Resurgence, Mediterranean Sea
In July 2007, >100 striped dolphins, Stenella coeruleoalba, were found dead along the coast of the Spanish Mediterranean. Of 10 dolphins tested, 7 were positive for a virus strain closely related to…
Gastrointestinal helminths of loggerhead turtles (Caretta caretta) from the western Mediterranean: constraints on community structure.
TLDR
A predictable composition coupled with low species richness in infracommunities might be accounted for partly by constraints on parasite acquisition at both host scales, and host factors limiting parasite recruitment may also contribute to depauperate and isolationist infracomunities.
Helminths as biological tags for franciscana (Pontoporia blainvillei) (Cetacea, Pontoporiidae) in Argentinian and Uruguayan waters
La faune d'helminthes de 46 dauphins de La Plata, Pontoporia blainvillei, de Necochea et Claromeco (Argentine) a ete comparee a celle qui a ete signalee dans des travaux precedents chez le meme hote…
Intestinal helminth fauna of the South American sea lion Otaria flavescens and fur seal Arctocephalus australis from northern Patagonia, Argentina
TLDR
Sea lions and furs seals from northern Patagonia harbour the intestinal helminth communities that could be predicted for otariids, i.e. the combination of species of the genera Corynosoma, Diphyllobothrium, Pseudoterranova, Contracaecum and, in pups, Uncinaria.
STATUS OF CORYNOSOMA (ACANTHOCEPHALA: POLYMORPHIDAE) BASED ON ANATOMICAL, ECOLOGICAL, AND PHYLOGENETIC EVIDENCE, WITH THE ERECTION OF PSEUDOCORYNOSOMA N. GEN
The possession of genital spines has been considered as a key taxonomic trait to differentiate Corynosoma from other genera of the Polymorphidae. However, Corynosoma currently consists of 2 groups of…
Morphological and molecular characterization of tetraphyllidean merocercoids (Platyhelminthes: Cestoda) of striped dolphins (Stenella coeruleoalba) from the Western Mediterranean
TLDR
Intra- and inter-sample variability in the morphology of the apical organ suggested that it degenerates during larval development, and suggests that each type of tetraphyllidean merocercoids may represent a single species, contrary to previous speculations based on morphological data.
Helminth Community Structure in Birds of Prey (Accipitriformes and Falconiformes) in Southern Italy
TLDR
It is concluded that in the Calabria region of southern Italy, each of the raptor species studied is distinct in terms of its helminth communities, and more diverse feeding habits of the host correspond with richer helmineth communities.
Phylogenetic relationship among genera of Polymorphidae (Acanthocephala), inferred from nuclear and mitochondrial gene sequences.
TLDR
It is observed that aquatic birds were the ancestral definitive hosts for the family with a secondary colonization and diversification to marine mammals and that amphipods were ancestral intermediate hosts and that the association with decapods represent episodes of secondary colonization that arose several times during the evolutionary history of the family.
