“…Permanent bodies of standing water used by anurans are embedded among patches of these vegetation formations and have their low‐lying adjacent areas composed of seasonally flooded grasslands that often inundate during the rainy season (Prado et al., 2005). The aquatic vegetation of these freshwater water bodies comprises erectophile grass‐like plants from Cyperaceae and Typhaceae families, and floating emergent plants from Pontederiaceae, Araceae, Salviniaceae and Nymphaceae families (Delatorre et al, 2020; Evans & Costa, 2013; Pott & Pott, 2000).…”

“…Second, we addressed the potential role of distinct ecological processes on the variation of species composition in nightly activity by fitting relationships on (c.1) the differences in species composition from the early-late night period and (c.2) the variance of such differences across the different monitored days patches of these vegetation formations and have their low-lying adjacent areas composed of seasonally flooded grasslands that often inundate during the rainy season (Prado et al, 2005).

Temporal scale in animal communities is often associated with seasonality, despite the large variation in species activity during a diel cycle. A gap thus remains in understanding the dynamics of short‐term activity in animal communities. Here we assessed calling activity of tropical anurans and addressed how species composition varied during night activity in assemblages along gradients of local and landscape environmental heterogeneity. We investigated 39 anuran assemblages in the Pantanal wetlands (Brazil) with passive acoustic monitoring during the peak of one breeding season, and first determined changes in species composition between night periods (early, mid and late) using two temporal resolutions (1‐ and 3‐hr intervals). Then, we addressed the role of habitat structure (local and landscape heterogeneity variables from field‐based and remote sensing metrics) and ecological context (species richness and phylogenetic relatedness) in determining changes in species composition (a) between night periods and (b) across days. Nocturnal calling activity of anuran assemblages varied more within the 1‐hr resolution than the 3‐hr resolution. Differences in species composition between early‐ and late‐night periods were related to local habitat structure and phylogenetic relatedness, while a low variation in compositional changes across days was associated with low‐heterogeneous landscapes. None of these relationships were observed using the coarser temporal resolution (3 hr). Our findings on the variation of calling activity in tropical anuran assemblages suggest potential trade‐offs mediated by fine‐temporal partitioning. Local and landscape heterogeneity may provide conditions for spatial partitioning, while the relatedness among co‐signalling species provides cues on the ecological overlap of species with similar requirements. These relationships suggest a role of niche dimensional complementarity on the structuring of these anuran assemblages over fine‐temporal scales. We argue that fine‐temporal differences between species in breeding activity can influence the outcome of species interaction and thus, addressing temporal scaling issues can improve our understanding of the dynamics of animal communities.

“…In synthesis, both the environmental factors, the habitat, as well as the taxonomic and functional properties of aquatic plants ( de Menezes-B et al, 2014;Delatorre et al, 2019), contribute to the attributes of the ecological communities in the two lakes. Despite the differences in the conductivity and pH of the lakes, the diversity of the different groups of organisms did not vary substantially likely emphasizing the permanent role played by the littoral environments of the Amazonian lakes.…”

Carbon from aquatic plants and periphyton in littoral zones subsidize food webs. Field work was carried out in two different lake types in the Colombian Amazon: a várzea (Yahuarcaca) and an igapó (Pacatúa). Plants in the littoral zone of várzea Lake had higher photosynthetic biomass compared to the plants of the littoral zone of igapó, but differences in root biomass were not significant. The two littoral zones contained a relatively high species richness and diversity (Shannon-Wiener Index) of organisms associated with the roots, although no significant differences existed between the two lakes. Littoral areas may be important in relatively isolated and physically fragmented large terrestrial landscapes such as the Amazon basin.

“…Rial (2006) reported that the diversity and abundance of aquatic plants change with water level variation. Periodic fluctuations in the water level allow the establishment of plant communities with changes in the dominance of certain species (Delatorre et al, 2019). During the dry period, when the water level decreases, some species establish taking advantage of the supply of nutrients from the decomposition of other plants (Pérez-Vásquez et al, 2015).…”

“…depending on the depth and frequency of flooding (Murray-Hudson et al, 2014). Thus, floods can act as a homogenizing factor that promotes changes n of aquatic macrophyte species, whether they increase or decrease during flood cycles (Catian et al, 2018;Delatorre et al, 2019). Consequently, this study aimed to examine macrophytes composition and their Spatial-temporal dynamic during different climatic periods in relationship with the water physicochemical variables in Santo Tomás wetland on flood plain Magdalena River (Colombian Caribbean).…”

Aim The associated flood events to floodplain of many rivers in the world affect the composition and structure of aquatic biota due the water levels variation can ensure ecological integrity of associated wetlands. This study describes the spatial and temporal variation in the macrophyte assemblage in the Santo Tomás wetland during seasonally flood-pulsed of the Magdalena River (North of Colombia). Methods For eight months, between 2017 and 2018 samplings were carried out in three stations for composition and abundance of aquatic macrophytes. Spatio-temporal pattern of richness was estimated with Chao methodology and vegetation cover was calculated using Kruskal-Wallis and U Mann-Whitney tests. A range abundance curve was used for species dominance between samplings and stations. A non-metric multidimensional scaling (nMDS) was used to analyze the Spatio-temporal distribution, Canonical Correspondence Analysis (ACC) was performed to relate the physicochemical variables to the species composition. Results A total of 24 species of aquatic plants distributed in 23 genera and 15 families were registered in the transects. The most abundant species (% of vegetation cover) were Ipomoea aquatica (19%), followed by Ludwigia helminthorrhiza (14%) and Eichhornia azurea (13%). The most frequent life form was free-floating, followed by the emergent one. The Spatio-temporal changes and the highest values of richness and vegetation cover in the Santo Tomás wetlands occurred during the filling and high waters period. L. helminthorrhiza, E. azurea, Pistia stratiotes, Neptunia oleracea, I. aquatica, Salvinia auriculata, and Hymenachne amplexicaulis were the most dominant species. The quality water of Santo Tomás Wetlands showed spatial and temporal variations during flooding pulse and some physicochemical variables such as organic matter (COD, BOD5), pH, depth, ammonia, and fecal coliforms were related to macrophyte community composition Conclusions Spatial and temporal changes of aquatic plants in Santo Tomás wetlands were related to the flooding pulse of Magdalena River.
