Life history and host specificity of Mediorhynchus centurorum Nickol 1969 (Acanthocephala: Gigantorhynchidae).

Acanthocephala of Louisiana Picidae with description of a new species of Mediorhynchus.

One hundred eighty-three woodpeckers of eight species collected in Louisiana were examined for Acanthocephala. Only the red-bellied woodpecker, Centurus carolinus, was infected. One of 53 was parasitized by an irrunature specimen of Mediorhynchus grandis; three by Centrorhynchus spinosus; 12 by Mediorhynchus centurorum sp. n. The new species of Mediorhynchus is distinguished by a trunk which is...

Alairhynchus, a new name for the genus Gigantorhynchus Sapelnikov & Malygina 1977 (Brachiopoda: Camarotoechioidea) preoccupied by Gigantorhynchus Hamann 1892 (Vermes: Acanthocephala).

The genus Gigantorhynchus (type species = G. dubius Sapelnikov & Malygina, 1977, by original designation) was established by Sapelnikov & Malygina (1977: 62) for a distinctive fossil brachiopod from Eastern Alai (Southern Tien Shan, Kyrgyzstan) which subsequently served as type of a subfamily (Gigantorhynchinae Savage 1996). However, the name Gigantorhynchus was preoccupied by a living worm gen...

Two species of acanthocephala from Australian fishes with description of Arhythmacanthus paraplagusiarum sp. n.

Developmental Stage of Parasites Influences the Structure of Fish-Parasite Networks

Specialized interactions tend to be more common in systems that require strong reciprocal adaptation between species, such as those observed between parasites and hosts. Parasites exhibit a high diversity of species and life history strategies, presenting host specificity which increases the complexity of these antagonistic systems. However, most studies are limited to the description of intera...

Comparison of Leptorhynchoides thecatus (Acanthocephala) recruitment into green sunfish and largemouth bass populations.

The degree to which host suitability is a reflection of host community structure in generalist parasites was studied experimentally in the common fish acanthocephalan Leptorhynchoides thecatus. Previous study has shown that green sunfish (Lepomis cyanellus) are required, and largemouth bass (Micropterus salmoides) are suitable (but not required) hosts, where they occur sympatrically in natural ...
