Global threats to pinnipeds
(Marine Mammal Science, 2012)
The 2008 IUCN (International Union for Conservation of Nature) review of the status of the world’s mammals identified marine mammals (IUCN 2008) as disproportionally threatened and data poor compared to their terrestrial ...
Human predation on pinnipeds in the Beagle Channel
(Nova Science Publishers, 2014)
The model established for subsistence patterns of hunter-gatherer societies which inhabited the islands located southwards Tierra del Fuego argues that pinnipeds constituted the most important food resource. This general ...
Atypical records of pinniped specimens housed in the Museo Argentino de Ciencias Naturales ‘Bernardino Rivadavia’
(Sociedad Latinoamericana de Especialistas en Mamíferos Acuáticos, 2014-01)
Pinnipeds are widely distributed in the Southern Hemisphere. The most common species that occur along the Argentinean coast are the southern elephant seal (Mirounga leonina), the southern fur seal (Arctocephalus australis) ...
Paleoindian pinniped exploitation in South America was driven by oceanic productivity
(Elsevier, 2014-05)
After centuries of pinniped exploitation, hunter-gatherers from the Atlantic coast of southern South America shifted in several occasions to other animal resources during the second half of the Holocene. The shift has been ...
From mammals back to birds: Host-switch of the acanthocephalan Corynosoma australe from pinnipeds to the Magellanic penguin Spheniscus magellanicus
(Public Library of Science, 2017-10)
Trophically-transmitted parasites are regularly exposed to potential new hosts through food web interactions. Successful colonization, or switching, to novel hosts, occur readily when ?donor? and ?target? hosts are ...
Pinniped Capture and Processing: A comparative Analysis from Beagle Channel (Tierra de Fuego, Argentina)
(Springer, 2017)
The Beagle Channel is located on the southern coast of the Isla Grande de Tierra del Fuego. It was inhabited by maritime hunter-gatherer-fishers from 6400 radiocarbon years BP to the late nineteenth century AD, when the ...
Cumulative Human Impacts on Pinnipeds Over the Last 7,500 Years in Southern South America
(Society for American Archaeology, 2018-09)
Our research program on this topic combines zooarchaeological and stable isotope studies from a historical ecology perspective. We originated this approach, and developed new analytical techniques, to better link archaeological ...
Zooarchaeological and Stable Isotopic Assessments on Pinniped-Human Relations in the Beagle Channel (Tierra del Fuego, Southern South America)
(John Wiley & Sons Inc, 2013-11)
Recent zooarchaeological investigations in the Beagle Channel region have shown long-term variations characterised by a high inter-taxonomic dominance of pinnipeds during the first moments of the archaeological sequence ...
Intraskeletal variability in stable isotope ratios of C and N among pinnipeds and cetaceans
(Wiley Blackwell Publishing, Inc, 2019-08)
Stable isotope analysis of C and N has become a popular method for addressing questions on the trophic ecology andhabitat use of marine mammals (Newsome, Clementz, & Koch, 2010; Rubenstein & Hobson, 2004). The method ...
Monitoring the occurrence of microplastic ingestion in Otariids along the Peruvian and Chilean coasts
(Elsevier, 2020)
Repeated reports of microplastic pollution in the marine pinniped diet have emerged in the last years. However, only few studies address the drivers of microplastics presence and the potential implications for monitoring ...
