Diet of Chaceon Ramosae (Decapoda, Brachyura) on the southern brazilian exclusive economic zone

, 2008
Among the great variety of species exploited in the Brazilian Exclusive Economic Zone (EEZ), the brachyuran decapods of the genus Chaceon (Geryonidae) stand out for their high commercial value.

The Effects of Noise on the Juvenile Life Stage of Crustaceans: Behavioral, Cellular, and Molecular Responses in Procambarus clarkii

Integrative Zoology, EarlyView.
Juvenile Procambarus clarkii exposed to noise exhibited behavioral changes, shifts in enzymatic activity, and altered expression of stress and immune genes. The findings highlight the sensitivity of invertebrate juveniles to anthropogenic acoustic pollution.

It's Complicated: How Sex, Family, and Season Affect Growth of a Sexually Size Dimorphic Spider

Integrative Zoology, EarlyView.
Extreme female‐biased sexual size dimorphism (SSD) in Nephilingis cruentata emerges when male and female growth trajectories diverge mid‐development. Seasonal effects influence both sexes similarly, but family effects are strongly sex‐specific. These patterns identify a critical developmental window for mechanistic studies of SSD.

Symbiosis with Sponge: Differential Predator Response with Hermit Crab Shell Types

Hermit crabs are important marine detritivores, and characteristically use discarded gastropod shells to cover their exoskeleton. However, some species use toxic symbiotic sponge shells instead, where the sponge dissolves and replaces their gastropod ...

Crushing and Cutting: Shape Variation and Morphological Integration Between the Claws of Two Swimming Crab Species (Brachyura: Portunidae)

Acta Zoologica, EarlyView.
ABSTRACT This study investigated shape variations and morphological integration between the components of crusher and cutter claws in two species of swimming crabs, Callinectes danae and Callinectes ornatus. The propodi and dactyli of the claws were analysed in males and females of both species, using geometric morphometric techniques to identify ...

Chitin oligosaccharides production fromenzymatic hydrolyzing crab shells

, 2008
In order to find an environment friendly way of producing chitin oligosaccharides from pretreated crab shells, we hydrolyze emulsified pretreated crab shells with chitinase whose gene is from Aspergillus fumigatus YJ-407 and cloned and expressed in E ...
