In 2012 we selected 35 experimental plots in Iris pumila L. (dwarf bearded iris) natural population
in natural reserve Deliblato Sand, Serbia. Flowering was monitored in 2013, 2014 and 2015
on selected more than 4 000 square meters, and opening of every individual flower on I. pumila
clones was recorded. Data revealed steady decline in number of flowering individual plants (ramets)
through analyzed years. The same spots were revisited in 2021 and 2022 flowering seasons
and occurence of all flowers was recorded by introducing drone digital photography in our
long term study. Preliminary analysis on the subsample of monitored spots reveals that detected
trend of decline in number of flowering ramets was not reversed after ten years. Detected long
term trend has significant implications for studies of evolutionary relationship between vegetative
and sexual modes of reproduction in this species, as well as possible conservation management
strategies in the face of environmental change. Additional methods that can reveal evolutionary
consequences of observed population dynamics on maintenance of within population genetic
polymorphism (with special emphasis on flower color polymorphism and variability on DNA level)
are discussed. We propose application of field spectography to huge flower color polymorphism
observed in analyzed species coupled with pigment HPLC analysis on studied population level,
as well as microsatellite genetic analyses of studied population composition as most suitable and
efficient lines of further research of those topics in the studied populations.
