Despite the wide range of functional roles performed by marine sponges they are still poorly
represented in many research, monitoring and conservation programmes. The aim of this …

Les éponges réagissent à la plupart des autres organismes des systèmes marins, en tant
que compétiteurs, symbiotes, hôtes de symbiotes, consommateurs et proies. L'étude et la …

Brachyuran crabs are sexually dimorphic, gonochoristic crustaceans (separate sexes, no
sex change). Dimorphism is expressed in the shape of the pleon (abdomen) and its …

Growth of crabs involves moulting through a series of instars. Most brachyurans have
indirect development, involving a planktonic dispersal phase followed by a benthic phase …

Morphometric and gonad maturity of Libinia spinosa on the coast of Mar del Plata,
Argentina, were assessed. In both sexes various morphometric features were measured to …

Eleven expeditions were undertaken to the Saint Peter and Saint Paul Archipelago to study
the reproductive biology of Grapsus grapsus, providing additional information on limb …

In this study we present results on epibionts on Zygochlamys patagonica from material
collected during monitoring cruises in different areas in the Argentine Sea. We update the …

Invasive marine crustaceans can exhibit population-level variation in reproductive traits that
are consistent with a response to stressful conditions near the range edge, or alternatively …

Ovalipes trimaculatus is a commercial species captured in the Mar del Plata coast,
Argentina. However, no studies were conducted in order to study its population features …

Sexual maturation in brachyurans has three different components: physiological,
morphologic and functional. The second is visualized by examining changes in the …
