Flexible foraging for finding fish: variable diving patterns in Magellanic penguins Spheniscus magellanicus from different colonies
(Wiley Blackwell Publishing, Inc, 2014-04-16)
Seabirds have to deal with environmental variability and are predicted to modulate foraging behavior to maximize fitness, with particularly strong selection pressure for optimal behavior during chick provisioning when ...
Effect of the lithospheric thermal state on the Moho interface: A case study in South America
(Pergamon-Elsevier Science Ltd, 2017-07)
Gravimetric methods applied for Moho recovery in areas with sparse and irregular distribution of seismic data often assume only a constant crustal density. Results of latest studies, however, indicate that corrections for ...
