data from the Devonian Villavicencio<br />

New terrestrial and marine palynomorphs of<br />
the lower part of the Villavicencio Formation,<br />
San Isidro Creek, Precordillera of Mendoza,<br />
Argentina, are evaluated. The palynomorph<br />
assemblage is dominated by miospores, and<br />
also contains acritarchs and scarce chitinozoans.<br />
Different processing methods have been<br />
tested due to the poor preservation state of the<br />
palynomorphs. The new slides provided abundant<br />
and diverse palynomorphs and allowed<br />
the recognition of 13 miospore species and<br />
two acritarch species. This review suggests a<br />
late Pragian to early Emsian age, thus confirming<br />
and refining previous palynological<br />
dating. The miospore assemblage may be correlated<br />
with the upper part of the Ems Biozone<br />
in terms of the Devonian miospore zonation of<br />
the Brazilian Amazon Basin. Palaeogeographically;<br />
acritarchs show perigondwanan<br />
affinities. In the light of this refined<br />
age determination, the stratigraphic and phytogeographic<br />
inferences for the Precordillera<br />
land plants should be reconsidered.<br />

change inferred from palynological data<br />

161-171<br />
An early-middle Holocene section in Bahia<br />
Lapataia (54 degrees 50'S, 68 degrees 34' W),<br />
Beagle Channel, Tierra del Fuego, Argentina<br />
has been examined taking into account its<br />
sporomorphs and organic-walled microplankton.<br />
The palynological assemblage suggests<br />
nearshore environments. Two relatively higher<br />
sea levels were identified by the increased<br />
abundance of organic-walled dinoflagellate<br />
cysts (Brigantedinium spp., Selenopemphix<br />
sp., Operculodinium centrocarpum sensu Wall<br />
and Dale, Spiniferites spp.), the acritarch<br />
Halodinium sp. and zoomorph remains (test<br />
linings of foraminifera and copepod eggenvelopes).<br />
The littoral vegetation at the time<br />
of the marine incursion was mainly arboreal,<br />
as can be seen in the pollen records by significant<br />
increase in Nothofagus dombeyi type frequencies,<br />
while a forest-steppe vegetational<br />
pattern developed regionally. After comparison<br />
with another nearby fossil marine terrace,<br />
the palynological analysis has demonstrated<br />
that these terraces represent the same transgressive-regressive<br />
event. The relative altitudinal<br />
differences between these terraces in the<br />
area may be the result of seismotectonic activity<br />
during the Holocene.<br />

Pollen analysis of barn swallow faeces (Hirundo<br />
rustica). ( 英 文 ). Bińka K. Acta Palaeobotanica,<br />
2005, 45(2): 187–194<br />
Pollen analysis of barn swallow faeces collected<br />
at ca. 12-day intervals since their arrival<br />
from Africa for late summer flights has been<br />
made. This study showed that through the<br />
alimentary canals of insect-consuming barn<br />
swallows, a high proportion of pollen of entomophilous<br />
plants from the close vicinity of<br />
the study area can be transmitted again into<br />
environment. Pollen of anemophilous plants,<br />
attached to the bodies of insects have also<br />
been passed to these areas. Also, grains of<br />
plants growing not only in the close vicinity<br />
but also occurring in more distant areas – sev-<br />
