ECOLOGICAL DYNAMICS IN THE FACE OF CLIMATE CHANGE, Nihal Doğruöz Güngör,Elif Özlem Arslan Aydoğdu, Editör, Nobel Yayınevi, İstanbul, ss.173-188, 2024
Climate change is already aff ecting biodiversity and is likely to intensify even more
noticeably over the next few decades unless serious action is taken. Even small changes
in temperature levels reveal in modelling and fi eld observations that wild species are at
risk of extinction unevenly, geographically. Change in species and ecological communities
continues to challenge the survival of endemic plant populations. Th e data obtained
in modelling based on the rates of change in the climate crisis, especially the risk
levels of endemic species, can be used as a guide in this process. It is time to take serious
measures in the climate change crisis. Average global temperatures have increased by
0.6 C in the last 140 years and continue to increase (1). Distributions, population size
and quality of species vary with warming (2, 3, 4). As a result of global warming, there
is an upward fl oristic migration in mountain vegetation (2). A special term is used for
places where these species survived high temperatures or eff ective humidity during
the Quaternary glaciations; “Glacier refuge” Temperature increase forecasts are critical
for preserving biodiversity. Species displaced due to climate forcing may remain in a
limited area. It would not be wrong to bring this term back to the agenda when talking
about these areas. Th e existence of glacial refugia has now been widely documented for
a large number of taxa, although the opposite, i.e. the retreat of cold-adapted species,
i.e. the term ‘interglacial refugia’, is less well known (5, 6), interglacial refugia are increasingly
popular as potential protected areas (7, 8, 9, 10, 11).
Marine communities are expected to show greater sensitivity to climate change than
terrestrial communities (12) because they have lower tolerance to temperature changes
(13). Th e eff ects of climate change observed in terrestrial regions are actually regions where
the change is greater (14). However, on land, it is predicted that the subtropical Temperate
zone, which includes Turkey, will have the highest rate of climate change (15, 16).
All over the world, the eff ects of climate change on plants are evaluated through
modeling studies. In a study where the impact of global warming on 25 rich spots was
evaluated through modeling, it was determined that changes in living spaces would
cause changes in fl oristic diversity. Global vegetation patterns that will emerge as a
result of projected future biome distributions have been presented (18).
