5. Biodiversity drivers
Drivers of Ponto-Caspian biodiversity Rise and Demise
5-9
Alteration of:
Nutrition patterns
Salinity
Water cycling patterns
Water chemistry
Climate
Glaciations
Tectonic movements
Transgression and Regressions
6. Drivers identification and
manipulation

Drivers of Ponto-Caspian biodiversity Rise and Demise
How?
-Dinocyst Taxonomical studies (it can be more elaborate and exact with other
fossil groups integration)
-Dinocyst biostratigraphy and age calibrations
-Dinocyst palaeoecological proxies (patterns like: Warm/Cold, Inner
neritic/Oceanic ,Outer neritic/Oceanic, C/PPC (Chorate forms to
Proximochorate + Proximate + Cavate forms), Salinity ,P/G
(Peridinoid/Gonyaulacoid) “Productivity”, etc.)
-Paleoclimatological and geochemical proxies (Paleothermometry “TEX 86” ,
ion-deficiency, stable isotopes, radio carbon dating, thermoluminescence,
Gas chromatography, etc.)
-Sedimentary data like sequences and Para-sequences studies, glacial
sediments, terrestrial sediments, etc.
-Gathering all obtainable data and then
Statistical Methods (unconstrained methods)
7. Why Statistical methods?
Linear relationship between species and environmental
changes, then NO need to unconstrained methods
But
GRADIENTS
Show non-linear relations to environmental alterations
Unconstrained methods that based on non-linear
responses to environmental curves and gradients
Species correspondence in methods like
Canonical Correspondence and
Detrended Correspondence.

8. Final Solution
8-9
Drivers of Ponto-Caspian biodiversity Rise and Demise
Interpreting data with unconstrained ordination methods:
-Identification of each species environmental preferences
in terms of temperature, productivity, nutrients, salinity,
etc.
-Identification of endemic taxa
-Identification of ultimate effective environmental
alteration
