“…Leaves of submerged plants are directly exposed to stress factors imposed by the water environment (Nekrasova et al, 2003). The increased surface area of submerged leaves in relation to their volume (development of striated, banded or lanceolate, usually very thin leaves) is also the best form of adaptation to efficiently carry out photosynthesis in conditions of weakened light (Ronzhina et al, 2001(Ronzhina et al, , 2004. The results obtained in this study were in agreement with those of other researchers (Ronzhina et al, 2004;Dar et al, 2013;Maksimović et al, 2020b), who reported a higher content of photosynthetic pigments in submerged compared to floating leaves.…”

It is known that aquatic macrophytes are an important part of freshwater ecosystems, and that they play a different role in their structure and functioning. Their presence and distribution depends on water temperature and transparency, nutrient content, conductivity, pH, chemical composition and water circulation. Therefore, the goal of our research was to determine the influence and interrelationship of physicochemical parameters of water on the content of photosynthetic pigments in aquatic macrophytes of Lake Necik, in the Ramsar area of Bardača (Republic of Srpska). Content of total chlorophyll (a + b) during the growing season (June–October) ranged from 0.231 to 1.145 mg g−1 FW in Phragmites communis Trin. ex Steud., from 0.061 to 0.541 mg g−1 FW in Salvinia natans L. (All.), from 0.063 to 0.626 mg g−1 FW in Utricularia vulgaris L. and from 0.063 to 0.443 mg g−1 FW in Ceratophyllum demersum L. Research has shown that floating and submerged macrophytes have a lower ratio of chlorophyll a/b compared to emergent hydrophytes, which is most likely the result of stress caused by increased light intensity and temperature. Seasonal variations in the content of photosynthetic pigments indicated that the species Phragmites communis proved to be more tolerant to the stress caused by the influence of various abiotic factors, while Salvinia natans proved to be more sensitive. Spearmon’s correlation coefficient of the physicochemical parameters of water and the concentration of photosynthetic pigments of macrophytes showed a significant influence of certain abiotic factors (temperature, transparency and nutrients) on the content of pigments in the leaves of Phragmites communis, Salvinia natans, Utricularia vulgaris and Ceratophyllum demersum L.

Increasing aridity is one of the most important trends of current climate change. Leaf functional traits suggest a substantial basis for assessing the aridity effects on vegetation. However, since plants possess diverse leaf morphology and anatomy due to different evolutionary history of taxa, the effect of aridity can hardly be revealed in a multispecies analysis. We studied leaf functional traits for 317 samples of 193 plant species in steppe and desert communities along a 1600-km latitudinal gradient in Southern Siberia (Transbaikalia, Russia) and Mongolia. We determined morphological leaf traits, quantitative anatomical parameters, physiological parameters, and photosynthetic pigments content. Different relevance of leaf traits for indication of plant response to climate has been demonstrated. The clearest changes in site-mean values along the aridity gradient were shown for leaf thickness, total chloroplast number per leaf area (N chl /A) and total surface area of chloroplasts (A chl /A) and cells (A mes /A) per leaf area. Unlike leaf size and leaf mass per area, these quantitative mesophyll parameters related to plant photosynthetic capacity were strongly correlated with climate. We found no evidence for a decrease in sizes of mesophyll cells with aridity, but cell volume as well as chloroplast number per cell were linked with plant functional type (PFT). We revealed an increase in N chl /A and A chl /A in desert-steppe species in comparison to steppe and forest-steppe vegetation types within each PFT of C 3-plants (C 3-dicot herbs, C 3-dicot shrubs, C 3-monocots and C 3-succulents). C 4-plants were generally characterized by low A chl /A and A mes /A, but had higher rate of CO 2-transfer through mesophyll and chloroplast surfaces. C 3-and C 4-plants differed in response to aridity and showed opposite trends in changes of leaf traits along the aridity gradient. We conclude that leaf mesophyll traits contribute to important mechanism of climatic adaptation in different PFTs along a large latitudinal gradient.
