Autor: Mariela L. Spinelli, Marcelo Pájaro, Patricia Martos, Graciela B. Esnal, Marina Sabatini, Fabiana L. Capitanio

Publikováno v: Scientia Marina, Vol 76, Iss 1, Pp 39-47 (2012)

We investigated the spatial distribution of the abundance, biomass and size of zooplankton (nauplii, calanoids, cyclopoids and appendicularians) in relation to the distribution of first-feeding larvae and eggs of Engraulis anchoita across the frontal

Reproduction and population structure of the salp Iasis zonaria (Pallas, 1774) in the southwestern Atlantic Ocean (34°30′ to 39°30′S) during three successive winters (1999–2001)

Autor: María Cristina Daponte, Mónica A. Palmieri, Beatriz E. Casareto, Graciela B. Esnal

Publikováno v: Journal of Plankton Research. 35:813-830

The salp Iasis zonaria is often found over the Argentine continental shelf of the southwestern Atlantic Ocean and, occasionally, its high densities dominate over other groups of zooplankton. Therefore, a better understanding of the basic aspects of i

Seasonal variability of metazooplankton in coastal sub-Antarctic waters (Beagle Channel)

Autor: Fabiana Lia Capitanio, Graciela B. Esnal, Gaston Ezequiel Aguirre, Gustavo A. Lovrich

Publikováno v: Marine Biology Research. 8:341-353

The aim of this study was to analyse the variability in the species composition and abundance of the metazooplankton community in different coastal areas of the Beagle Channel (southern tip of South America) during a seasonal cycle. Sampling was cond

Publikováno v: Estuarine, Coastal and Shelf Science. 85:97-106

Among tunicates, the small planktonic appendicularians generally comprise a significant fraction of the mesozooplankton of estuarine environments. However, no spatio-temporal studies nor estimation of some ecological parameters such as biomass or pel

Publikováno v: Journal of the Marine Biological Association of the United Kingdom. 86:1215-1220

The gonadal development and morphometry of Appendicularia sicula (Appendicularia: Fritillariidae) were studied by means of histological sections and from the measurement of several characters. Based on morphometric measurements, the ingestion and cle

Appendicularians: an important food supply for the Argentine anchovy Engraulis anchoita in coastal waters

Autor: M. Pájaro, Graciela B. Esnal, Fabiana Lia Capitanio

Publikováno v: Journal of Applied Ichthyology. 21:414-419

Summary The stomach contents of 532 adult specimens of the Argentine anchovy, Engraulis anchoita, caught in coastal waters of the Argentine Sea from 1994 to 1996, were analyzed. Larger amounts of food were found in the stomachs of anchovies collected

Coupling between pelagic and benthic systems has been described in numerous shallow water communities. In Potter Cove, where pelagic primary production is low (not only during the Antarctic winter but also during the summer), the rich benthic communi

Autor: Marcos Tatián, Graciela B. Esnal, Ricardo Sahade

Publikováno v: Scopus-Elsevier

The reproductive biology of the common Antarctic ascidian Cnemidocarpa verrucosa (Lesson) (Tunicata, Ascidiacea) was studied in a shallow-water population at Potter Cove, South Shetland Islands. Samples were taken monthly by SCUBA diving over a 15 mo
