Flora and basins of Angarida

Devonian plants in Siberia present protracted pioneer succession. Research
into the survivourship dynamics of early plant communities upon the
palaeocontinent Angarida have demonstrated that transgression and
volcanogenic nutrient influx were key to the survival of colonising
plants. Taxic proportions show that migrating taxa entered Angarida from
the southwest, Kuznetsk and Minusinsk basins, dispersing across the
continent in waves through central areas northwards. The patterns of
dispersal are consistent throughout the Devonian. Increased nutrient load
from the active pulses of the Viluy-Yakutsk Large Igneous Province,
biogeomorphic ecosystem engineering, and the increased biomass of
Angaridan plants are assisted by Late Devonian transgression. These
cumulative factors can be linked to the Late Devonian marine extinctions
observed in Siberia.
