Egg production of the burrowing shrimp Callichirusseilacheri (Bott 1955) (Decapoda, Callianassidae) in northern Chile
Fecundity was positively correlated with female size; however, correlations were allometric, which might be related to the elasticity of the abdomen. Expand
Population biology of the burrowing shrimp Callichirus seilacheri(Decapoda: Callianassidae) in northern Chile
The main breeding period lasted from autumn to winter (May to August, peaking in June), and co-occurred with decreasing water temperatures and the presence of a sediment layer covering the burrows. Expand
Population distribution, sexual dimorphism, and reproductive parameters in the crab Pinnixa valdiviensis Rathbun, 1907 (Decapoda: Pinnotheridae), a symbiont of the ghost shrimp Callichirus garthi (Retamal, 1975) in the southeastern Pacific
It is argued in favour of additional long-term descriptive and experimental studies to reveal the mating tactics used by both males and females of P. valdiviensis to test for monogamy considering that the few other studied species of Pinnixa White inhabit their respective hosts as male-female pairs.

Abundance and behavior of the sally lightfoot crab (Grapsus grapsus)in the colony of the brown booby (Sula leucogaster)in the São Pedro and São Paulo Archipelago
The low frequency of crabs in the colony around noon shows that the crabs avoid insolation, hiding in shady places and tidal pools, and dead birds, in the Sao Pedro and Sao Paulo Archipelago. Expand
