Reproductive biology of the crab Munida subrugosa (Decapoda: Anomura: Galatheidae) in the Beagle Channel, Argentina
TLDR
Munida subrugosa was sampled monthly from November 1997 to November 1999 in the Beagle Channel by means of an epibenthic trawl and found that females and males attained physiological maturity at 9·9 and 8·0 mm CL respectively, and males reached morphometric maturity at 24·4 mm’CL.

Distribution, reproductive and energetic conditions of decapod crustaceans along the Scotia Arc (Southern Ocean)*
TLDR
A new index was used to measure the energy devoted to reproduction by relating the energy contents of the egg mass/ovary plus hepatopancreas and the energy content of the whole body, which revealed that the energy investment in reproduction was larger in caridean shrimps than in galatheid crabs.

Feeding ecology of the crab Munida subrugosa (Decapoda: Anomura: Galatheidae) in the Beagle Channel, Argentina
Munida subrugosa is the most abundant galatheid crab species in the Beagle Channel (55°S 68°W) off Tierra del Fuego, Argentina. Samples of crabs and the epibenthic community were taken on a monthly…

SEASONAL CHANGES IN DRY MASS AND ENERGETIC CONTENT OF MUNIDA SUBRUGOSA (CRUSTACEA: DECAPODA) IN THE BEAGLE CHANNEL, ARGENTINA
TLDR
M. subrugosa is used as an energetic storage organ, because RDM and EC increased before vitellogenesis and moulting, and the R DM and EC investment in gonadal development was significant higher in females.

Life History of the Galatheid Crab Munida subrugosa in Subantarctic Waters of the Beagle Channel, Argentina
TLDR
The reproductive cycle of Munida subrugosa started in June, and was reflected by the maximum size of oocytes, the maximum value of gonadosomatic index in both females and males, and by the proportion of ovigerous females.

Morphological differences between ‘subrugosa’ and ‘gregaria’ morphs of adult Munida (Decapoda: Anomura: Galatheidae) from the Beagle Channel, southern South America
TLDR
The difference between the two discriminant functions provides an objective decision rule for the classification of both species/morphs and the linear relationships of wet and dry masses on size, for use in biomass estimations of Munida spp.

DISTRIBUTION OF BENTHIC INVERTEBRATES IN THE BEAGLE CHANNEL, ARGENTINA
TLDR
Las muestras se tomaron estacionalmente en tres lugares diferentes del Canal Beagle y en two estratos de profundidad, 15-40 m y 70-259 m, donde no se observaron variaciones estaciones en the produccion secundaria del macrozoobentos.

OCCURRENCE OF LITHODES CONFUNDENS (DECAPODA: ANOMURA) IN THE INTERTIDAL OF THE SOUTHWESTERN ATLANTIC
TLDR
The size of animals progressively increased from ∼ 50 mm carapace length (CL) in October to ∼ 105 and 75 mm CL in December for males and females, respectively, and 100 mm CL is suggested as the legal size for fishery management purposes.
