The glass slides were randomly collected with two replicates every sampling day. The total number of glass slides analyzed in each hydrological period was 36, for 72 slides in total. Periphytic material was removed from the substratum, fixed and preserved with 0. Zur Vervollkommnung der quantitativen phytoplankton-methodic. Stuttgart: Schweizerbart. The species density was estimated according to Ros Ros, J.
Barcelona: Omega. The biovolume was estimated according to Hillebrand et al. Biovolume calculation for pelagic and benthic microalgae. Journal of Phycology, vol. We considered species richness from the quantitative analyses. Periphytic algae composition and diversity can be found in Rodrigues and Bicudo a Rodrigues, L. A total of and 93 species were found during the high and low water periods, respectively Rodrigues and Bicudo, a Rodrigues, L.
These species were analyzed according to four categorical functional traits: size class based on the phytoplankton classification of Reynolds Reynolds, CS. Vegetation processes in the pelagic: a model for ecosystem theory. Germany: Ecology Institute.

The differences in species community attributes richness, density or biovolume between hydrological periods were tested by paired T test, using the hydrological periods as a factor. We analyzed richness, density and biovolume of the functional traits in both hydrological periods and in community dynamics along colonization. To address our first question, we used a factorial two-way analysis of variance to test the differences, using hydrological periods, days of colonization and traits as factors, and their interactions.
A non-metric multidimensional scaling analysis NMDS was applied to the matrix of richness, density and biovolume of species traits to summarize the patterns in both hydrological periods. This analysis was used to address our second question. A species functional matrix was constructed for both hydrological periods based on four species traits.
The functional matrix was standardized and converted into a distance matrix through the mixed-variables coefficient of distance proposed by Pavoine et al. On the challenge of treating various types of variables: application for improving the measurement of functional diversity. Oikos, vol. The cophenetic correlation was observed to assess how the structure of the distance matrix was preserved in the grouping. The functional diversity was achieved from the dendrogram by the index mean pairwise distance MPD and taking into account the density of traits in this analysis.
This measure is considered baseline i. Exploring the phylogenetic structure of ecological communities: an example for rain forest trees. American Naturalist, vol. To address our last question, the differences between functional diversity values of hydrological periods were tested by T test, using hydrological periods as a factor. R: A language and environment for statistical computing. The R Foundation. Access in: 05 Feb. The densities ranged from 9. The biovolume values ranged from Species richness varied between 20 and 40 species in high waters, with the highest values on day 8, and between 23 and 43 species in low waters with the highest values on day For species richness, R-strategist species prevailed in both hydrological periods Figure 1 , 1A ; Figure 1 , 1B.
For the density, in the high water period Figure 1 , 2A , there was a predominance of C-S species, and in the low water period Figure 1 , 2B , R-strategist species prevailed. Considering species biovolume, in both hydrological periods, C-S strategist species stood out in almost days of colonization Figure 1 , 3A ; Figure 1 , 3B. Firmly attached species prevailed in richness during the last days of colonization during the high water period Figure 2 , 1A.
In the low water period Figure 2 , 1B , the loosely attached species prevailed during all days of colonization. For the species density, during the high water period, loosely attached species prevailed most days Figure 2 , 2A. In the low water period Figure 2 , 2B , firmly attached species stood out in density. In relation to the biovolume, during the high water period Figure 2 , 3A , firmly attached species prevailed during all successions.
In the low water period Figure 2. Unicellular species prevailed in richness during both hydrological periods Figure 3 , 1A ; Figure 3 , 1B. Considering density, filamentous species stood out during almost all of the days of colonization during the high water period Figure 3 , 2A , and in the low water period Figure 3 , 2B , the pattern was reversed, with a predominance of unicellular followed by filamentous species.
Regarding species biovolume, filamentous species prevailed throughout colonization during the high water period Figure 3 , 3A , and during the low water period Figure 3 , 3B , this growth form prevailed up to the 10 th colonization day, with a subsequent increase of colonial species. Microperiphytic species prevailed in richness in both high Figure 4 , 1A and low water periods Figure 4 , 1B during colonization.
Considering species density, nanoperiphytic species prevailed in the high water period Figure 4 , 2A and microperiphytic species in the low water period Figure 4 , 2B. With respect to biovolume, during the high water period Figure 4 , 3A , microperiphytic species stood out up to the 10 th colonization day, and in the low water period Figure 4. The NMDS showed a stress of 0. Thus, the differentiation in the trait richness between hydrological periods indicated that unicellular species, the size class microperiphyton and the R-strategists species were more related to the initial days of colonization in low waters, whereas firmly and filamentous species were more related to high waters Figure 5A.
The NMDS performed with the trait density showed a stress of 0. Thus, the differentiation in the trait density between hydrological periods indicated that unicellular, firmly, and R-strategists species were more related to low waters, whereas filamentous and C-S strategists species were more related to most days of colonization during high waters Figure 5B. The NMDS performed with the traits biovolume showed a stress of 0. Thus, although this ordination was not significant, maybe in terms of the number of replicas, the pattern in this ordination showed that firmly and filamentous species were more related to the last days of colonization in high waters, during the peak of biomass Figure 5C.
The cophenetic coefficients of functional dendrograms of communities between high and low waters were 0. This result indicated that much of the distance matrix structure was preserved in the grouping of species. The functional diversity was generally higher during the high water period. This trend was modified on the final days of colonization Figure 6. During high water, the highest values of functional diversity occurred between the 10th and 12th days of colonization.
During low water, the highest values of functional diversity occurred between the 12th and 16th days. The flood pulse effect promoted a differentiation in the structure and dynamics of periphytic algae functional traits and functional diversity along a short-term succession process at the Pau Veio Lake. During the colonization and succession processes of periphytic algae, changes occur in the composition of species taxonomic and arrangement of organisms in the matrix physiognomy Tuji, Tuji, A.
Variation in periphyton biomass and species composition in Lake Okeechobee, Florida USA : distribution of algal guilds along environmental gradients. Community structure attributes can respond differently to these changes, and in the present study, the density and richness were the attributes that showed significant differences between hydrological periods.
Studies of phytoplankton or periphyton are usually based on cell volume or biovolume , a measurement that estimates the contribution of each taxonomic group or taxon to the primary production Lavoie et al. Diatoms and biomonitoring: should cell size be accounted for? The structure of these communities can also be evaluated through the density or relative abundance, but these measurements do not represent the differences of cell sizes, and the influence of abundant small cells can be underestimated relative to larger taxa.
These two measurements are complementary, and some bioindication studies using periphytic algae have emphasized the use of biovolume as the best method Reavie et al. Algal assemblages for large river monitoring: Comparison among biovolume, absolute and relative abundance metrics.
Ecological Indicators, vol. In our study, the density and richness were the most sensitive to the influence of the flood pulse, in addition to being a measure that allows a better identification of succession stages. Among the functional strategies of periphytic algae, C-S species dominated in density in the high water period, when there was a lower availability of nutrients.
The homogenizing effect of the flood pulse Thomaz et al. The instability caused by the pulse may be changed in a few days, and environmental conditions may return to normal, which might have favored the C-S species, which can generally establish and dominate in stable environments with low to moderate intensity of disturbance and under mesotrophic conditions Carrick and Steinman, Carrick, HJ.
The low environmental instability and the moderate availability of nutrients can be responsible for the predominance of C-S species Biggs et al. Note that there was a greater contribution of C-S species in biovolume in both hydrological periods. This group is composed of unicellular or filamentous organisms, usually with a medium size, which grow vertically or prostate Carrick and Steinman, Carrick, HJ.
A distinct response was verified for the richness of functional strategies. R-strategist species prevailed in richness in both periods and in density in the low water. The R species group consists of pioneer species, primary colonizers that grow rapidly in highly variable environments by tolerating frequent disturbances with a high variability of resources Carrick and Steinman, Carrick, HJ. In physically stable environments, they can also persist by remaining entangled in the matrices along with C or S-strategist species Biggs et al.
A similar result for the dominant functional strategies was reported by Ferragut and Bicudo Ferragut, C. In a control condition, similar to our experiment without the flood pulse effect low water period , R-strategist species dominated the entire succession process. On the other hand, Dunck et al. Regarding the attachment to the substratum, the loosely attached species prevailed in density in both periods.
Differences in composition and attachment produce varied three-dimensional physiognomic structures in the periphyton matrix Tuji, Tuji, A. In succession processes, this matrix consists of layers according to the availability of nutrients, space, light and degree of disturbance Lowe, Lowe, RL. Periphyton patterns in lakes.
This can explain the predominance of loosely attached species in both periods, from the washout promoted by the flood pulse in the high water period, or by the high connectivity with the river in the low water period. The height inside the periphyton matrix is important for providing greater access or increasing the individual probability of acquiring light and resources from above or from the middle Stevenson, Stevenson, RJ.
Barcelona: Ediciones Omega. These organisms present differentiated structures or cells for attachment to substrates, which favored their permanence in the high water period, under the flood pulse effect. In turn, unicellular species are generally smaller and can have the ability to move, which favors displacement inside the periphyton matrix in the search of available resources.
These traits may have favored their greater density in the low water period. Moreover, the cell size is a strategy that influences the contribution of each species to the total community biomass, and the cell division rate is influenced by this characteristic, as a small cell has a faster growth rate than a large cell Cox, Cox, EJ.
What is the basis for using diatoms as monitors of river quality? Use of algae for monitoring rivers. Innsbruck: University of Innsbruck. Among the size classes evaluated, nanoperiphyton species prevailed in the high water period with lower nutrient availability, and microperiphyton species predominated in the low water period.
Studies have reported a reduction in nanoperiphyton species with increased enrichment of environments and a trend to increase the size of organisms in environments with higher nutrient availability Cattaneo et al. In succession processes, in general, the biomass peaks are related to climax in succession Biggs et al. The higher biomass density and biovolume in both periods was related to the 12th and 16th days of colonization, similar to that recorded in Brazil by Felisberto and Rodrigues Felisberto, SA.
For the functional diversity, the highest values corresponded to peaks in biomass in both periods. This result is an indication that communities in a biomass peak during a short-term succession process also have greater functional diversity. Theory predicts that greater differences in species traits Cadotte et al. Beyond species: functional diversity and the maintenance of ecological processes and services.
Journal of Applied Ecology, vol. Linking traits between plants and invertebrate herbivores to track functional effects of land-use changes. Experiments, reviews and meta-analyses have shown that functional diversity is one of the best predictors of available ecosystem function Petchey and Gaston, Petchey, OL.
Thus, the results indicate that these communities in biomass peak may have greater efficiency in the functioning of ecosystems. Although the means of functional diversity between hydrological periods were not different in both hydrological periods, the highest values of functional diversity were related to the high water period.
This likely occurred due to the expansion of the flooding area and connectivity promoted by the flood pulse in this period. This event provided an increase in temporary habitat available for the species. Because algae possess passive and generally unlimited dispersal Finlay, Finlay, BJ. Global dispersal of free-living microbial eukaryote species. Science, vol. Variance partitioning of deconstructed periphyton communities: does the use of biological traits matter? These results are similar to those found by Dunck et al.
They also concluded that the high water period enhances the variety of niches and that the dispersal is eased by the flood pulse, thereby allowing the development of more species with different functional traits. In summary, our study demonstrated that the flood pulse promoted alterations in short-term successional processes of periphytic algae.
The flood pulse favored a greater development of C-S strategists, loosely attached, filamentous and nanoperiphytic species in succession processes in a semi-lotic ecosystem. The lack of this effect led to the predominance of R-strategists, loosely attached, unicellular and microperiphytic species. We demonstrated that functional traits play an important role in communities and that the highest values of functional diversity were related with the biomass peak during the short-term succession and high water hydrological period.
