“…Although, the new generation methods (e.g. DNA barcoding) provide new information on the diff erent taxa's identity and evidently are promising in exploring the diversity of microscopic plants (Tapolczai et al 2016), it still seems that for palaeoecological reconstructions there is no better approach than the morphology based identifi cation.…”

Abstract:Mountain lakes have special importance in the neo-and palaeolimnology. Th e diatom fl ora of mountain regions of Europe has been studied in detail, but less attention was paid to the Romanian part of the Carpathians. Siliceous algae of mountain lakes (1,740-2,122 m a.s.l.) were studied in the Retezat Mts (South Carpathians, Romania). Sediment samples were collected in the deepest points of twenty-three pristine lakes between 2011 and 2014. A total of 152 species and intraspecifi c diatom taxa were found during this study (excluding the representatives of the two most diverse diatom genera Eunotia and Pinnularia). Altogether 140 taxa were listed and nomenclaturally checked from the previously published results. 79 common species and some rarely reported taxa are illustrated by means of light-(LM) and scanning electron microscope (SEM), and 40 other are presented here only with LM images. A partial diatom checklist is presented with 217 items, 80 of them have been recently recorded for the Retezat Mountains. Th is compilation focuses on small celled (< 20 μm) diatoms. Th e main aim is to help the identifi cation to the hardly visible, lightly silicifi cied and recently described forms, instead of repeating the earlier published data. Th is guide consist of a detailed light and scanning electron microscopy documentation of the diatom fl ora, based on 752 LM and 188 SEM pictures. New Humidophila and Staurosira taxa are presented and a new combination is proposed for Achnanthes helvetica var. minor. Th e detailed, illustrated guide hopefully will be a useful manual for ecological and palaeoecological surveys in the future.

“…Traits can furthermore serve to disentangle multiple interacting influential factors (Baattrup‐Pedersen, Göthe, Riis, & O'Hare, ; Lange, Townsend, & Matthaei, ). Trait‐based approaches have been used for different purposes in terrestrial plants (Grime, ; Tilman, ) and macroinvertebrate (Menezes et al., ), but only very recently been considered for freshwater algae (Lange et al., ; McGill et al., ; Tapolczai, Bouchez, Stenger‐Kovács, Padisák, & Rimet, ), particularly in phytoplankton studies (Colina, Calliari, Carballo, & Kruk, ; Padisák, Crossetti, & Naselli‐Flores, ; Reynolds, Huszar, Kruk, Naselli‐Flores, & Melo, ; Thomas, Kremer, & Litchman, ). Recent studies have shown the advantages of applying traits for biomonitoring of freshwater ecosystems and for biodiversity conservation (Di Battista, Fortuna, & Maturo, ; Lange et al., ; Litchman & Klausmeier, ; McGill et al., ; Menezes et al., ; Soininen et al., ).…”

There has been increasing interest in algae‐based bioassessment, particularly, trait‐based approaches are increasingly suggested. However, the main drivers, especially the contribution of hydrological variables, of species composition, trait composition, and beta diversity of algae communities are less studied. To link species and trait composition to multiple factors (i.e., hydrological variables, local environmental variables, and spatial factors) that potentially control species occurrence/abundance and to determine their relative roles in shaping species composition, trait composition, and beta diversities of pelagic algae communities, samples were collected from a German lowland catchment, where a well‐proven ecohydrological modeling enabled to predict long‐term discharges at each sampling site. Both trait and species composition showed significant correlations with hydrological, environmental, and spatial variables, and variation partitioning revealed that the hydrological and local environmental variables outperformed spatial variables. A higher variation of trait composition (57.0%) than species composition (37.5%) could be explained by abiotic factors. Mantel tests showed that both species and trait‐based beta diversities were mostly related to hydrological and environmental heterogeneity with hydrological contributing more than environmental variables, while purely spatial impact was less important. Our findings revealed the relative importance of hydrological variables in shaping pelagic algae community and their spatial patterns of beta diversities, emphasizing the need to include hydrological variables in long‐term biomonitoring campaigns and biodiversity conservation or restoration. A key implication for biodiversity conservation was that maintaining the instream flow regime and keeping various habitats among rivers are of vital importance. However, further investigations at multispatial and temporal scales are greatly needed.

“…Furthermore, it should also be taken into account that certain tube-346 forming taxa (e.g. E. silesiacum) are able to change their life form character and they can be 347 motile also (Rimet and Bouchez, 2012;Tapolczai et al, 2016). So it is possible, that the 348 strong negative correlation of S4 groups containing tube forming taxa with inorganic nutrients 349 may be due to changing their life form to motile.…”

29 30Functional classification based on species traits brought a revolution in community ecology, 31and also boosted phytoplankton and in phytobenton (diatom) research. Several studies 32 stressed the usefulness of phytoplankton functional groups in ecological status assessment, 33and there is also a strong emphasis to use combined traits in ecological assessments of diatom 34 assemblages. The Combined Eco-Morphological Functional Groups (CEMFGs) help to reveal 35 species-environmental correlations, which can be hidden, controlling traits separately. between the correlations of CEMFGs-P or CEMFGs-RB and abiotic factors were 50 hypothesised in the case of those functional groups which contained reassigned taxa with high 51 frequency and/or abundance. Our results confirmed this hypothesis. Furthermore, the present 52 study also highlighted the relevance of well-defined trait classification. Abundant and/or 53 frequent taxa, which are able to change their life forms, can modify significantly the 54 relationship between the functional group containing them and environmental factors. In the 55 future, both field and laboratory studies should focus on revealing the circumstances, which 56 cause the mentioned changes in traits of diatoms. 57 58
