SUBANTARCTIC LIMPET POPULATIONS TODAY AND HUMAN IMPACT ABOUT 1,400 YEARS AGO

Age, growth and length frequency data of the subantarctic intertidal limpets Nacella (Patinigera) magellanica and Nacella (Patinigera) deaurata (gmelin, 1791) were investigated at Bahía Laredo in the eastern part of the Straits of Magellan (South america). data were obtained from (i) recent populati...

Conventional 14C age determination showed the shells of both limpet-species from this midden to be about 1,400 years old (S.d. ± 75 years). growth rates of recent and ancient populations were found to be in the same range, but higher than determined in previous studies carried out in the magellan region. the missing of large-sized limpets from the ancient length frequency distributions may indicate considerable exploitation of limpet populations by patagonian natives about 1,400 years ago.info:eu-repo/semantics/openAccessUniversidad de MagallanesAnales del Instituto de la Patagonia v.38 n.1 20102010-01-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-686X2010000100006en10.4067/S0718-686X2010000100006
