Holocene changes in the trophic ecology of an apex marine predator in the South Atlantic Ocean by Vales, Damián Gustavo, Cardona, Luis, Zangrando, Atilio Francisco Javier, Borella, Florencia, Saporiti, Fabiana, Prosser Goodall, Rae Natalie, Rosa de Oliveira, Larissa, Crespo, Enrique Alberto

“…Stable isotope ratios of nitrogen and carbon in bone collagen have been used to reconstruct the foraging ecology of South American fur seals (Arctocephalus australis) in the southwestern South Atlantic Ocean since the Middle Holocene, a region inhabited by hunter-gatherers by millennia and modified by two centuries of whaling, sealing and fishing. Results suggest that the isotopic niche of fur seals from Patagonia has not changed over the last two millennia (average for the period: δ13C2200-0BP = −13.4 ± 0.5‰, δ15N2200-0BP = 20.6 ± 1.1‰). …”

Isotopic niche partitioning between two apex predators over time by Drago, Massimiliano, Cardona, Luis, Franco Trecu, Valentina, Crespo, Enrique Alberto, Vales, Damián Gustavo, Borella, Florencia, Zenteno, Lisette, Gonzáles, Enrique M., Inchausti, Pablo

“…This recent dietary change of South American fur seals can be explained by at least two non-mutually exclusive mechanisms: (i) the decrease in the abundance of sympatric South American sea lions as a consequence of small colony size and high pup mortality resulting from commercial sealing; and (ii) the decrease in the average size of demersal fishes due to intense fishing of the larger class sizes, which may have increased their accessibility to those eared seals with a smaller mouth gape, i.e., South American fur seals of both sexes and female South American sea lions.…”

Prehispanic food in the lowlands of Tucumán (Argentine): a first approach to its analysis by Caria, Mario, Gómez Augier, Julián, Miguez, Gabriel E.

“…This makes it possible to distinguish, at a first approach, between those obtained by hunting-gathering and fishing, from those produced by crop harvesting or raising animals. …”

Archaeology of the Pilcomayo, Bermejo and Paraguay rivers by Lamenza, Guillermo N., Calandra, Horacio A., Salceda, Susana A.

“…This has resulted in differential organizations occurring in the archaeological record, either fishing societies with reduced mobility and extensive interaction networks; others that emphasized hunting, fishing and gathering with high residential mobility, or agropastoral societies with greater degree of sedentarism that included cultivation at diverse scales among their economic activities.…”

Protection of coast and loss of the palaeontological heritage: the case of Punta Hermengo (Miramar, Buenos Aires Province) by Cenizo, Marcos, Soibelzon, Esteban, Tonni, Eduardo Pedro

“…As noted by the authors, this type of activity is neither unique nor recent in the area; since 2006 similar “barriers” were built to the north of Miramar (as part of the same municipal project) and a few years ago a singular paleontological and archeological site, located a few meters north of Punta Hermengo, close to the fishing pier, almost disappeared. This site, already mentioned by Carlos Ameghino at the beginning of the XXth century, was partially covered by remains of old road concrete and then by accumulation of sand from the beach generated by the construction of a breakwater. …”
