Effects of the environmental conditions and seasonality on a population survey of the Andean condor in the tropical Andes.

Background: Among the New World vultures, the Andean condor is considered one of the most culturally and ecologically important species. However, their populations are declining over their entire distributional range. In response, conservation strategies have been implemented in many countries to reverse the increasing extinction risk of this species.

Oceanography time series reveals annual asynchrony input between oceanic and estuarine waters in Patagonian fjords.

The postglacial Patagonian fjord system along the west coast of southern South America is one of the largest stretches of the southern hemisphere (SH) fjord belt, influenced by the SH westerly wind belt and continental freshwater input. This study reports a 3-year monthly time series (2017-2020) of physical and biogeochemical parameters obtained from the Reloncaví Marine Observatory (OMARE, Spanish acronym) at the northernmost embayment and fjord system of Patagonia. The main objective of this work was to understand the land-atmosphere-ocean interactions and to identify the mechanisms that modulate the density of phytoplankton.
