INFESTATION OF THE FALSE KING CRAB PARALOMIS GRANULOSA (DECAPODA: LITHODIDAE) BY PSEUDIONE TUBERCULATA (ISOPODA: BOPYRIDAE) IN THE BEAGLE CHANNEL, ARGENTINA

- Biology
- 1 October 1999
The finding of crabs without bopyrids, but with distended branchial chambers, shows that some crabs survive the infestation of Paralomis granulosa, and suggests that the reproductive potential of the crab population is not seriously affected by the sterilizing effect of the parasite.

Fiddler crabs collected at the southern end of the Samborombón Bay, Río de la Plata estuary, Argentina, from February 1995 to March 1996 showed reproductive activity gradually decreased, and by winter, all the adult female parasites showed empty marsupia, and the growth of immature parasites appears to stop in winter and resume in spring.

An intertidal population of Claudicuma platense, a cumacean that inhabits the Rio de la Plata bottom, was sampled for 15 months and the size of marsupial females and the fecundity decrease from overwintering, to spring, to summer generations, each generation exhibits a linear, but different, female size-fecundity relationship.

The biodiversity of the isopods and cumaceans from Burdwood Bank is typically Magellanic, and there is little correspondence between this fauna and that from the Antarctic Peninsula and Scotia Arc.
On the occurrence of the genus Paranebalia (Crustacea: Phyllocarida: Leptostraca) in northern Patagonia, Argentina

- 2 February 2010
A large number of specimens collected in Nuevo, San Jose and San Matias Gulfs, northern Patagonia, in the years 2003 to 2007 agree with the diagnostic characters of Paranebalia longipes, but the description and subsequent redescriptions of this species are not sufficiently detailed for a reliable identification.

REMARKS ON THE GENUS ANATHELGES (ISOPODA: BOPYRIDAE), WITH A NEW RECORD FROM THE BEAGLE CHANNEL, ARGENTINA
- M. Diaz, D. Roccatagliata
- Biology
- 2006
This collection of Anathelges has made it possible to describe and illustrate four sequential female stages of this parasite, to extend the geographic range of distribution of this genus to the southern tip of South America, and to discuss the taxonomic value of some of the characters used to distinguish species in this genus.
