We studied the diversity of copepods throughout the annual cycle in Patagonian coastal waters.
In this study we analyzed the zooplankton annual succession, especially of copepods, in Patagonian coastal waters. The annual cycle had two marked periods, autumn / winter and spring / summer. During autumn / winter the copepod Calanoides carinatus dominated the community. However, in spring / summer smaller species such as the harpacticoid Euterpina acutifrons were found. The temporal pattern of copepods can be explained by food availability and environmental factors (e.g., temperature and solar radiation) although the abundance of predators can be also important to shape the community.
