Embryonic development of four species of palaemonid prawns (Crustacea, Decapoda): pre-naupliar, naupliar and post-naupliar periods
Provedor de dados: 104
Autores: Müller,Yara; Ammar,Dib; Nazari,Evelise.
The embryonic development of four species of the family Palaemonidae was studied under laboratory conditions. Adults of Macrobrachium olfersi (Wiegman, 1836), Macrobrachium potiuna (Müller, 1880), Palaemon pandaliformis (Stimpson, 1871) and Palaemonetes argentinus (Nobili, 1901) were collected in Santa Catarina Island, Santa Catarina, Brazil and maintained at 26ºC. The following embryonic characters were analyzed: egg shape, yolk organization and cleavage plane, naupliar and post-naupliar appendages, stomodeum, optical lobes, eyes, telson, embryo curvature and the space occupied by the embryo in the egg. Different rates of development were observed for the four species, with M. potiuna showing the longest time of embryogenesis. The species studied followed...

Biologia reprodutiva de Macrobrachium olfersii (Wiegman) (Crustacea, Decapoda, Palaemonidae) coletados na Ilha de Santa Catarina, Brasil
Provedor de dados: 104
Autores: Ammar,Dib; Müller,Yara Maria Rauh; Nazari,Evelise Maria.
The aim of this study is to characterize the reproductive features of Macrobrachium olfersii (Wiegman, 1836) from Santa Catarina's lsland. The animals were collected in freshwater streams of the Ratones Hidrografic Basin (site A1) and at the Peri's Pond (site A2). In the laboratory, the procedures of sexual differentiation were carried out to classify the individuais in males, females or ovigerous females, followed by the determination of total weight (g), quelipod relative weight (g) and total length (mm). The eggs were removed from the ovigerous females and counted. Sexual maturity and fecundity were analyzed based in the dimensions and number of eggs carried by ovigerous females. The water temperature on the capture sites varied from 17 to 29ºC...

Biologia dos Palaemonidae (Crustacea, Decapoda) da bacia hidrográfica de Ratones, Florianópolis, Santa Catarina, Brasil
Provedor de dados: 104
Autores: Müller,Yara Maria Rauh; Nazari,Evelise Maria; Ammar,Dib; Cargnin Ferreira,Eduardo; Beltrame,Ingrid Thaís; Pacheco,Cristiane.
Biological aspects of palemonids, collected from March, 91 to December, 95 in the Ratones Hidrographic Basin, Florianópolis, Santa Catarina, have been investigated. Individuals of different sizes of Macrobrachium acanthurus (Weigmann, 1836), Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium olfersii (Weigmann, 1836), Macrobrachium potiuna (Müller, 1880), Palaemonetes argentinus Nobili, 1901 and Palaemon pandaliformis (Stimpson, 1871) were registered. These prawns, showed reproductive strategies, typical of the Palaemonidae (Rafinesque, 1815), associated to species particularities, and seem to adapt to different environmental conditions.

Aspectos da reprodução de Palaemon pandaliformis (Stimpson) (Decapoda, Palaemonidae) no manguezal de Ratones, Florianópolis, Santa Catarina
Provedor de dados: 104
Autores: Müller,Yara Maria Rauh; Nazari,Evelise Maria; Bressan,Cristine Maria; Ammar,Dib.
Biometric and reproductive aspects of Palaemon pandaliformis (Stimpson, 1871) from Ratones Mangrove, Florianópolis, Santa Catarina, have been investigated. Individuals were monthly collected from August, 91 to July, 93 and the temperature and salinity registered. Biometry, sex-ratio, sexual maturity, fecundity and reproductive cycle have been determined. The temperature showed defined temporal distribution. This species presents animal reproductive cycle, relatively high individual and populational fecundity, and the ovigerous females were larger than males and other females of the same species.

Estagiamento de embriões de Macrobrachium olfersi (Wiegman) (Crustacea, Palaemonidae) através de critérios morfológicos nos dias embrionários
Provedor de dados: 104
Autores: Simões-Costa,Marcos S.; Pacheco,Cristiane; Nazari,Evelise M.; Müller,Yara M. R.; Ammar,Dib.
Em embriões de Macrobrachium olfersi (Wiegman, 1836) foram analisadas as características morfológicas bem como o dia do desenvolvimento em que estas características surgiram. Machos e fêmeas de M. olfersi foram coletados na Ilha de Santa Catarina e colocados em aquários de água doce, na temperatura de 26°C e ciclo escuro e claro de 10:14 horas. Fêmeas ovígeras foram monitoradas diariamente para retirada de uma amostra de 20 ovos da câmara incubadora. O desenvolvimento embrionário foi caracterizado através do sistema de estagiamento diário. Embriões vivos e fixados foram analisados (48x) em intervalos de 24 horas (dia embrionário). O índice do olho foi calculado em cada dia embrionário, a partir do aparecimento da pigmentação no olho. O desenvolvimento de...
