abstract = {The objective of this study was to explore
the environmental factors having the greatest influence
on the distribution and abundance of epipelic diatom
species in different wetlands in southern Spain.
We previously defined four groups of conductivity
categories: fresh (< 0.8 mS cm−
1), oligosaline
(< 8 mS cm−
1), mesosaline (8–30 mS cm−
1) and
eusaline (> 30 mS cm−
1). A dbRDA analysis
performed on a subset of 36 of the 53 wetlands,
using a total of 25 environmental variables, showed
that five environmental variables (conductivity, pH,
wetland area, silicates, and total suspended solids)
were the best explanatory variables for the diatom
assemblage, with conductivity being the main
explanatory variable. Nonmetric multidimensional
scaling (nMDS) analysis performed on the set of 53
wetlands revealed significant differences in diatom
composition among the four conductivity groups. The
key species in the eusaline group were Tryblionella
pararostrata, Halamphora sp.1 and Cocconeis
euglypta, whereas in the mesosaline and oligosaline
group, these were Navicula veneta, Tryblionella
hungarica and Nitzschia inconspicua. Finally, in the
fresh group dominated Achnanthidium minutissimum,
Navicula veneta and Gomphonema exilissimum. This
study on epipelic diatoms can therefore contribute
to the knowledge of these organisms in a European
region with a high diversity of wetland typologies.},
