Lateralization (handedness) in Magellanic penguins [PDF]
PeerJ, 2019 Lateralization, or asymmetry in form and/or function, is found in many animal species. Brain lateralization is considered adaptive for an individual, and often results in “handedness,” “footedness,” or a side preference, manifest in behavior and ...

Climate change increases reproductive failure in Magellanic penguins. [PDF]
PLoS ONE, 2014 Climate change is causing more frequent and intense storms, and climate models predict this trend will continue, potentially affecting wildlife populations. Since 1960 the number of days with >20 mm of rain increased near Punta Tombo, Argentina.

Penguins exploit tidal currents for efficient navigation and opportunistic foraging. [PDF]
PLoS BiologyAnimals navigating in fluid environments often face forces from wind or water currents that challenge travel efficiency and route accuracy. We investigated how 27 Magellanic penguins (Spheniscus magellanicus) adapt their navigation strategies to return ...

Genetic Sexing of the African Penguin, <i>Spheniscus demersus</i> Using Noninvasive Guano and Molted Feather Samples. [PDF]
Ecol EvolThis study developed a noninvasive method for the DNA extraction and PCR‐based genetic sexing of S. demersus using guano and molted feather samples. Two primer sets (CHD1F/R & 2550F/2718R) were used that target sex‐specific length polymorphisms in the CHD1‐Z and CHD1‐W genes on the CHD1 sex chromosomes. Using methods optimized for the extraction of DNA

A fearful scourge to the penguin colonies: Southern giant petrel (Macronectes giganteus) predation on living Magellanic penguins (Spheniscus magellanicus) may be more common than assumed [PDF]
Ecology and EvolutionSouthern giant petrels (Macronectes giganteus) are important consumers that range across the oceans throughout the southern hemisphere. In Argentina, previous studies have shown they eat primarily pinnipeds and penguins, which they are assumed to ...
