| Zusammenfassung |
| Heinrich event 4 (H4) is well documented in the North Atlantic Ocean as a
cooling event that occurred between 39 and 40 Ka. Deep-sea
cores around the Iberian Peninsula coastline have been analysed to
characterize the H4 event, but there are no data on the terrestrial response
to this event. Here we present for the first time an analysis of terrestrial
proxies for characterizing the H4 event, using the small-vertebrate
assemblage (comprising small mammals, squamates and amphibians) from
Terrassa Riera dels Canyars, an archaeo-palaeontological deposit located on
the seaboard of the northeastern Iberian Peninsula. This assemblage shows
that the H4 event is characterized in northeastern Iberia by harsher and
drier terrestrial conditions than today. Our results were compared with
other proxies such as pollen, charcoal, phytolith, avifauna and large-mammal
data available for this site, as well as with the general H4 event
fluctuations and with other sites where H4 and the previous and subsequent
Heinrich events (H5 and H3) have been detected in the Mediterranean and
Atlantic regions of the Iberian Peninsula. We conclude that the terrestrial
proxies follow the same patterns as the climatic and environmental
conditions detected by the deep-sea cores at the Iberian
margins. |
