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 کاملFORAGING ECOLOGY AND DIET TREE SWALLOWS FEEDING SELECTIVITY OF NESTLINGS l
We studied the foraging ecology of a population of Tree Swallows (Tachycineta bicolor) breeding in New York State over a period of 5 years. While feeding nestlings, adult Tree Swallows tended to spend most of their time within sight of their nest box and less than 12 m above the ground. Major insect taxa captured include Diptera, Hemiptera, and Odonata, ranging in length from mainly O-10 mm, wi...
متن کاملNatural and anthropogenic factors affecting the feeding ecology of a top marine predator, the Magellanic penguin
Understanding how top predators respond to natural and anthropogenically induced changes in their environment is a major conservation challenge especially in marine environments. We used a multidisciplinary approach to explore the mechanisms through which a typical central-place forager, the Magellanic penguin (Spheniscus magellanicus) from the Chubut province of Argentina, responds to variatio...
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 ...
