Mesoscale variability in the habitat of the Humboldt Current krill, spring 2007

Abstract: Mesoscale eddies are prominent structures in the world's oceans generating a high degree of spatial and temporal heterogeneity that influences zooplankton distribution. Euphausiids (krill) are a key zooplankton group mainly inhabiting coastal upwelling areas where high productivity, advection, and eddy kinetic energy (EKE) play pivotal roles in the distribution and structure of zooplankton. We analyzed the spatial distribution of the Humboldt Current krill, Euphausia mucronata, in relation to environmental var… Show more

“…2000 km offshore, despite the oceanographic barriers associated with the water mass distribution detailed above. These findings concur with previous investigations on the distribution patterns of euphausiids which demonstrated that eddies can effectively retain zooplankton for long periods of time while transporting them to the oligotrophic region (Riquelme-Bugueño et al, 2015).…”

“…2), suggested that the mesoscale activity in the SEP is an important process favouring the dispersion, advection, mixing and a possible ecological connectivity of hyperiids among zones. The importance of mesoscale processes influencing the transport and mixing of the population has been demonstrated for phytoplankton and other zooplankton groups (Hormazabal et al 2004;Correa-Ramirez et al 2007;Morales et al 2010;Riquelme-Bugueño et al 2015), and it may thus explain the notable presence of Eupronoe minuta, Primno brevidens, and Lestrigonus schizogeneios/L. shoemakeri across all zones.…”
