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 ...

Foraging distance affects reproductive success in Magellanic penguins [PDF]
Marine Ecology Progress Series, 2009 Foraging distance affects reproductive success and other demographic parameters in seabirds and pinnipeds. We tracked breeding Magellanic penguins Spheniscus magellanicus at Punta Tombo, Argentina using satellite transmitters from 1996 to 2006 (n = 148 males, 57 females) to investigate the variability in foraging distance and its effects on ...

P465 Aspergillosis in free-ranging Magellanic penguins [PDF]
Med Mycol, 2022 Abstract Poster session 3, September 23, 2022, 12:30 PM - 1:30 PM Aspergillosis is an opportunistic fungal disease caused by the Aspergillus genus, mostly by Aspergillus section Fumigati. Captive Magellanic penguins are vulnerable to Aspergillus infection, being this mycosis a limiting factor during ...

Feather Microbiota Landscapes: Biogeography and Phenology Shape Feather Microbiota Traits in a Migratory Seabird in a Subantarctic Ecosystem. [PDF]
Mol EcolABSTRACT It is known that phenological changes (i.e., behavioural and sometimes morphological and physiological traits that repeat annually) influence the wildlife gut microbiota. However, it remains largely unknown to what extent geographic variation could modulate the effect that phenology has on wildlife microbiota.

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
