| dc.description.abstract | The Antarctic Chilean peninsula, is characterized for being stable in its oceanographic conditions. Nevertheless, its coastal zones, such as bays, may have more variable physical conditions, both spatially and temporally. It has been observed that a remarkable interaction between the oceanographic conditions and spatial distribution patterns of zooplankton occurs. However, there is no good understanding of how these interactions affect the horizontal and vertical distribution of zooplankton living in these areas. The present study shows the changes that occur at the level of the zooplankton community structure, specifically in the copepods assembly of FĂldes Bay. The results show that copepods of the Oithonidae family are abundant in coastal areas of the bay meanwhile Calanidae copepods are abundant in zones adjacent to Bransfield Strait and found only in low abundance at the interior of the bay. These findings indicate differences in the ensemble of copepods along the bay with changes in the abundance and distribution of dominant groups of copepods commonly found in the Antarctic Peninsula and Drake Passage waters. | en |
| dc.description.abstract | La PenĂnsula Antártica Chilena, se caracteriza por ser estable en su condiciĂłn oceanográfica, sin embargo sus zonas costeras como bahĂas pueden presentar condiciones fĂsicas variables tanto espacial como temporalmente. Se ha señalado que existe una importante interacciĂłn entre las condiciones oceanográficas y patrones de distribuciĂłn espacial del zooplancton, sin embargo, no existe mayor evidencia acerca de cĂłmo esta interacciĂłn afecta la distribuciĂłn horizontal y vertical del zooplancton que habita estas zonas. El presente estudio muestra evidencias de los cambios que ocurren a nivel de estructura comunitaria del zooplancton, especĂficamente en el ensamble de copĂ©podos al interior de BahĂa FĂldes. Los resultados muestran que copĂ©podos de la familia Oithonidae son abundantes en zonas costeras de la bahĂa mientras que copĂ©podos de la familia Calanidae son abundantes en zonas contiguas al Estrecho Bransfield encontrándose en escasa abundancia al interior de la bahĂa. Estos hallazgos indican que existen diferencias en el ensamble de copĂ©podos a lo largo de la bahĂa con cambios en tĂ©rminos de abundancia y distribuciĂłn de grupos dominantes encontrados comĂşnmente en la PenĂnsula Antártica y aguas cercanas al paso Drake. | es |
