In all cores, sediment magnetism reflects the interplay between catchment material and the in situ production of bacterial magnetite (magnetotactic bacteria). In the lakes, the earliest Holocene sediments record a waning catchment input that we attribute to rising lake levels and increased tree cover in the catchment. From not, vert, similar9000 to 5000 yr BP, both lakes become anoxic, a consequence of water-mass stratification driven by high lake levels. Bottom-water anoxia also developed in the Adriatic, with sapropel S1 produced between not, vert, similar 9000 and 7000 yr BP. Subsequently, the lake and Adriatic mineral magnetic records show evidence for increased catchment delivery, consistent with pollen evidence for Bronze Age deforestation. In the lakes, this evidence is first recorded at not, vert, similar4300 yr BP and a number of distinct clearance events are recorded. In comparison, at Adriatic site RF93-30, lithogenic input increases abruptly at not, vert, similar3500 yr BP and is followed by a slowly changing record of waxing and waning sediment delivery.\n\nInter-site comparisons of palaeomagnetic data point to a possible link between the magnitude of the bacterial magnetite component and the recorded magnetic inclination. The sites are at near identical latitudes and have similar sediment accumulation rates but the Adriatic sites have a core-average magnetic inclination that is some 10\u00B0 steeper than the lake average values. We suggest that the large dipole moment of the magnetosome chains, which in life produce the passive alignment of the bacterium along the local geomagnetic field line, produce a more faithful (albeit smoothed) record of the geomagnetic field."@en . @prefix ns13: . prodotto:ID49204 pubblicazioni:editore ns13:ID252 ; prodottidellaricerca:prodottoDi modulo:ID5991 , istituto:CDS080 , dipartimento:CDS501 ; pubblicazioni:autoreCNR unitaDiPersonaleInterno:MATRICOLA22369 . @prefix parolechiave: . prodotto:ID49204 parolechiave:insiemeDiParoleChiave . ns12:ID435782 pubblicazioni:rivistaDi prodotto:ID49204 . ns13:ID252 pubblicazioni:editoreDi prodotto:ID49204 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID49204 .
