13. Efeito da anoxia e da recuperação sobre o metabolismo de carboidratos em brânquias de Chasmagnathus granulatus alimentados com uma dieta rica em proteínas ou em carboidratos
O presente trabalho teve como objetivo determinar os efeitos da anoxia ambiental e da recuperação da anoxia sobre o metabolismo da glicose em brânquias anteriores e posteriores de caranguejos Chasmagnathus granulatus alimentados com uma dieta rica em carboidratos ou proteínas. Os animais foram coletados e aclimatados em aquários com aeração constante

14. Impact of a power plant cooling system on copepod and meroplankton survival (Bahía Blanca estuary, Argentina)
The impact of a power plant cooling system in the Bahía Blanca estuary (Argentina) on the survival of target zooplanktonic organisms (copepods and crustacean larvae) and on overall mesozooplankton abundance was evaluated over time. Mortality rates were calculated for juveniles and adults of four key species in the estuary: Acartia tonsa Dana, 1849 and Euryt

15. Effects of the burrowing crab Chasmagnathus granulata (Dana) on meiofauna of estuarine intertidal habitats of Patos Lagoon, Southern Brazil
Este trabalho avalia os efeitos do caranguejo Chasmagnathus granulata sobre a meiofauna em três ambientes intermareais, durante um prolongado período de exposição (uma marisma emersa, um plano de lama emerso e outro submerso), numa enseada estuarina da Lagoa dos Patos. Nematódeos e ostrácodes foram os organismos dominantes, seguidos por copépodes e tu

16. Infaunal recruitment patterns in soft bottom habitats of the Patos Lagoon estuary, southern Brazil: influence of Chasmagnathus granulata (Brachyura, Grapsidae) disturbance
A comparative study of the infaunal recruitment patterns among disturbed surface sediment mounds around Chasmagnathus granulata Dana, 1851 burrows and undisturbed adjacent sediments was done in two intertidal soft bottom habitats (an upper and a lower mudflat zone) in an estuarine inlet of Patos Lagoon, southern Brazil. The most abundant infaunal organisms w

17. Desenvolvimento larval de Chasmagnathus granulata Dana (Crustacea, Decapoda, Grapsidae), em laboratório: I. estudo da morfologia de cerdas nas fases de zoea e megalopa e das variações dos padrões corporais da fase de megalopa
The study of Chasmagnathus granulata Dana 1851 was done with the setae morphology point of view. The main objective of this description was to find differents kinds of morphologicals types of setae. During this work anomalous structures were found in megalopal phase, such as: many kinds of rostral and lateral spines, as well as many kinds of spines on the te

18. Acute and chronic effects of cadmium on blood homeostasis of an estuarine crab, Chasmagnathus granulata, and the modifying effect of salinity
Whole body oxygen consumption and some hemolymph parameters such as pH, partial pressure of gases, level of ions and lactate were measured in the estuarine crab Chasmagnathus granulata after both acute (96 h) and chronic (2 weeks) exposure to cadmium at concentrations ranging from 0.4 to 6.3 mg/l. In all instances, the crabs developed hemolymph acidosis, but

19. Anticholinesterase effect of eserine (physostigmine) in fish and crustacean species
As caraterísticas cinéticas (Km) de colinesterases do caranguejo Chasmagnathus granulata, o camarão Farfantepenaeus paulensis e o peixe Odontesthes bonaeriensis foram comparadas e correlacionadas com os efeitos anticolinesterásicos da eserina (fisostigmina). Nos crustáceos, o valores estimados de Km foram aproximadamente 5-8 vezes maiores do que aquele

20. Effects of serotonin and fluoxetine on blood glucose regulation in two decapod species
One of the best known crustacean hormones is the crustacean hyperglycemic hormone (CHH). However, the mechanisms involved in hormone release in these animals are poorly understood, and thus constitute the central objective of the present study. Different groups of crustaceans belonging to diverse taxa (Chasmagnathus granulata, a grapsid crab and Orconectes l

21. Composição e distribuição dos Crustácea (Decapoda) na Lagoa do Peixe, Rio Grande do Sul, Brasil
The Lagoa do Peixe ("Peixe's Lagoon") is located between Atlantic Ocean and Lagoa dos Patos and is 30 Km long and 0,5-2,0 Km wide (31º13'S, 50º55'W -31º26'S, 51º09'). For one year, the composition and distribution of Crustácea Decapoda were analyzed monthly (from July/1994 to June/1995), in seven subareas (terrestrial border and aquatic area) and physic
