Temporal, diel and spatial variability of decapod larvae from St Paul's Rocks, an equatorial oceanic island of Brazil
- A. G. Koettker, A. Freire, Paulo Y. G. Sumida
- Biology

Two different decapod larval assemblages inhabit the marine environment of Saint Paul’s Rocks, differentiating the inlet from the surrounding oceanic waters. Larvae of the crab Grapsus grapsus and of… Expand
Meroplankton spatial structure and variability on Abrolhos Bank and adjacent areas, with emphasis on brachyuran larvae
- A. G. Koettker, R. Lopes
- Biology
- 1 November 2013
The spatial distribution of meroplanktonic stages of benthic invertebrates was investigated on the Abrolhos Bank and adjacent shelf and oceanic areas during winter. Meroplanktonic larvae occurred at… Expand
Vertical distribution of benthic invertebrate larvae during an upwelling event along a transect off the tropical Brazilian continental margin

- 2010
Abstract Abundance and composition of marine benthic communities have been relatively well studied in the SE Brazilian coast, but little is known on patterns controlling the distribution of their… Expand
Spatial and temporal distribution of decapod larvae in the subtropical waters of the Arvoredo archipelago, SC, Brazil
- A. G. Koettker, A. Freire
- Biology
