Y. Fernandezjalvo et al., POLLEN COMPOSITION IN OWL PELLETS AND THEIR ENVIRONMENTAL IMPLICATIONS, Comptes rendus de l'Academie des sciences. Serie II. Sciences de la terre et des planetes, 323(3), 1996, pp. 259-265
Pollen records provide valuable insights into past environments, but s
ometimes this record may be biased by taphonomic processes. In order t
o investigate how assemblages are disturbed, pollen composition of owl
pellets from different areas are here compared with local pollen rain
from these areas. The results of this preliminary investigation sugge
st that pollen from. pellets is biased by the hunting behaviour of pre
dators and the selective incorporation of rodent species in their diet
. Differences between pollen composition in pellets and the surroundin
gs where they accumulate have implications for the interpretation of p
ast environments based on material derived from owl pellets. Taphonomi
c investigation of pollen in pellets not only helps in recognizing bia
ses in the pollen composition, but also provides a more detailed inter
pretation of the local environment.
