Reproductive aspects of marine cladocerans Penilia avirostris and Pseudevadne tergestina (Crustacea, Branchiopoda) in the outer part of Guanabara Bay, Brazil.
The objective of this study was to report on some aspects of marine cladoceran reproduction in Guanabara Bay. Samples were collected during 1985 using a conical net with 200 microm mesh. Two species were identified: Penilia avirostris and Pseudevadne tergestina. Both species disappeared from the plankton in winter. Two months before this phenomenon, parthenogenetic females displayed reduction i...
متن کاملEmbryonic development time of Penilia avirostris Dana, 1852 in a tropical bay in Brazil.
Development time of embryos in the brood pouch of the cladoceran Penilia avirostris Dana, 1852, was estimated by collecting zooplankton daily for 15 days in surface water of Guanabara Bay, Brazil. Each day the maturity stage of embryos of 90 parthenogenic females was noted. Total development time (egg to birth) varied from 2 to 3 days, the immature phase (stages I to IV) being generally longer ...

متن کاملSeasonal dynamics of macroinfaunal key species inhabiting shallow soft - bottoms in the Bay of Blanes ( NW Mediterranean )
Within the frame of a wider research project on the littoral ecosystem of the Bay of Blanes (NW Mediterranean), the dynamics of shallow soft-bottom macroinfaunal assemblages of medium-to-fine-sand sediment communities of Spisula subtruncata have been followed since March 1992. These assemblages exhibited a very predictive annual cycle. Abundance and biomass rose sharply during spring, followed ...
متن کاملیافته علمی کوتاه: بررسی پراکنش مکانی و زمانی رده تالیاسه (Urochordata:Thaliacea) در آبهای پیرامون جزیره هرمز، ایران
The class Thaliacea belongs to Urochordata which branched from phylum chordata. Thaliacea have three orders: Doliolida (Cyclomyaria), Pyrosomatida and Salpida (Desmomyaria) and all are considered marine plankton, holoplankton and microphages. These animals feed by filtering water through their body. The aim of this research was to identify and study the ecological processes of the tunicates in ...
