Ecological View of Limb Regeneration in the Mangrove Crab Goniopsis Cruentata (latreille 1803) (crustacea: Brachyura: Grapsidae), Maceió, Alagoas, Brazil
نویسندگان
چکیده
Studies focusing regeneration are incomplete without considering autotomy (Maginnis 2006). According to this author, autotomy is the process of limb loss, allowing multiple benefits to an organism (the most prevalent is predator avoidance), commonly improving the immediate survivorship. Factors such as contact with toxins and pesticides, long limbs stuck in crevasses during foraging, crabs harvest by fisherman, cannibalistic attacks and intra and interspecific may also promote shed of appendages.

Breeding Period of the Crab Goniopsis Cruentata (latreille 1803) (crustacea: Brachyura: Grapsidae) in Na Estuarine Area, Maceió, Alagoas, Brazil
Reproduction is certainly the main mechanism by which to guarantee species continuity, being a result of adaptative processes determined by evolutionary pressures to improve offspring survival (Hartnoll & Gould 1988). Breeding period is defined as the time interval in which ovigerous females may be found. According to Sastry (1983), it is the result of the complex interactions of endogenous and...
متن کاملBreeding period in the mangrove crab Goniopsis cruentata (Decapoda: Grapsidae) in Northeast Brazil.
The brachyuran crabs are iteroparous species which present a high diversification of reproduction patterns, which may have evolved as a species-specific response to environmental conditions. Tropical species commonly present a year-round reproduction due to stable environment conditions. Goniopsis cruentata is a crab species widely distributed along the Western Atlantic, inhabiting practically ...
متن کاملFirst Zoeal Stages of Geograpsus Lividus and Goniopsis Pulchra from Panama Confirm Consistent Larval Characters for the Subfamily Grapsinae (crustacea: Brachyura: Grapsidae)
The first zoeal stages of Geograpsus lividus (H. Milne Edwards, 1837) and Goniopsis pulchra (Lockington, 1876), both obtained from laboratory hatched material in Panama, are described and illustrated. Geograpsus was one of the few genera of Grapsinae for which larval data were unavailable. Zoeal features are compared with those of other genera included in Grapsinae, and several shared morpholog...
متن کاملMangrove vegetation and community structure of brachyuran crabs as ecological indicators of Pondicherry coast, South east coast of India
Baseline ecological studies of Pondicherry mangroves are important for monitoring, management and conservation of mangrove ecosystems. A brachyuran crab faunal assemblage at four stations of Pondicherry mangroves is described and monthly samplings were made during September 2008 – August 2009. Totally 22 species of brachyuran crabs belonging to 12 genera and 5 families were recorded crabs bel...

Introduction Mangrove forests are productive ecosystems found along the coastal zones of Brazil, providing several profitable resources such as timber, medicinal products, natural dye, fish, crustaceans, and molluscs. For the littoral dwellers of Northeast Brazil, the Brachyura crabs are a major economic resource. The main species they commercialize are the 'goiamum' (Cardisoma guanhumi), 'siri...
