“…In each plot, the circumference at breast height (1.3 m above the soil) of every living tree that met the inclusion criterion (minimum circumference: 10 cm) was recorded. For trees with multiple stems, we included those of which the square root of the sum of squares of each stem's circumference met the inclusion criterion (Scolforo and Mello 1997, Souza et al 2021a,b2021b). Tree identification was performed by a specialist in the field or by comparisons with herbarium specimens.…”

In this study, we characterized and compared vegetation types associated with geomorphological units susceptible to distinct flooding levels. Differences in vegetation are related to landform variations. We aimed to 1) characterize the vegetation structure and quantify community compositional differences among landforms and 2) compare landforms soil characteristics and how these correlate with the tree vegetation. The study area is located in the Brazilian Caatinga domain, near the Verde Grande river, a tributary of São Francisco river (14°54′38ʺS, 43°42′53ʺW). We allocated six plots in each of the five landforms sampled (from wettest to driest sites): 1) marginal dike (RF – riparian forest), 2) upper terrace (RWF – riparian wetland forest), 3) lower terrace (WF – wetland forest), 4) lower plain (OFF – occasionally flooded forest) and 5) upper plain (UF – unflooded forest). We ran a non‐metric multidimensional scaling, produced a Venn diagram, and performed a principal component analysis (PCA) on the soil data (compared through a Tukey test at 5% significance after a significant ANOVA). A total of 1422 individuals, 26 families, 70 genera and 89 species were recorded. The NMDS revealed two distinct floristic groups: one group is associated with landforms with assumed higher flood frequency (RF, RWF, WF) and one with less frequently flooded landforms (OFF and UF). The RF, OFF, and UF landforms contained exclusive species (that only occurred in the plots of a particular landform). The species Geofroea spinosa (Fabaceae) was responsible for 70% of the total biomass recorded in the landforms RWF and WF. The soil analysis showed a gradient of soil acidity and fertility related to water saturation, whereby the most frequently flooded plots had the highest acidity values and highest fertility. We found that flood‐related conditions significantly influence tree community structure and species distribution in this floodplain in the Brazilian Caatinga domain.

“…The Brazilian Neotropical flooded forests have been intensively studied in Amazon and Pantanal wetlands (Wittmann et al 2010, 2013, Aldana et al 2017, Souza et al 2021a,b2021b). Flooding systems may contribute uniformly spatially to main floristic units across Amazon (Oliveira‐Filho et al 2021).…”

“…Characterized by seasonal floods and droughts caused by the overflowing of the Paraguay River and its tributaries, the Pantanal ecosystem is significantly influenced by the Cerrado (savanna), Atlantic rainforest, Chaco (seasonally dry forest), and the Amazon rainforest. This results in a diverse array of ecosystems, including forestland, humid areas, shrubland-savanna, grassland, pasture, and cropland (Souza et al, 2021;Marengo et al, 2021;Correa et al, 2022;Higa et al, 2022). The Pantanal provides vital ecosystem services, such as hosting rich biodiversity (e.g., over 2500 native plant species), freshwater supply, food security, climate regulation, scenic beauty, and diverse sociocultural elements, including indigenous and traditional populations (Pott & Pott, 2021).…”

“…Lithosols are present in the Província Serrana region, and the western Pantanal contains mollic planosols, rhodic ferralsols, and orthic solonetz. Figure 3B illustrates the general patterns of vegetation, but additional floral diversity relates to the spatial distribution of soil types (de Souza et al, 2021). Broadly, the soils are divided into forest formations, arboreal cerrado, herbaceous cerrado, chaco (woody steppic savanna), monodominant formations, and mixed vegetation (dos Santos Vila da .…”

Pantanal Basin river muds from source to sink: compositional changes in a tropical back-bulge depozone

The Pantanal Basin is a low-gradient back-bulge analog for distal depozones associated with retroarc foreland basin systems in the geological record. Extensive lowland environments including fluvial megafans, floodplains, wetlands, and lakes make up the Pantanal Basin today, with detrital sediment sources located along basin-margin plateaus and remnants of ancient orogenic belts. Here, we examine the chemical composition and mineralogy of modern fine-fraction fluvial sediments using X-ray methods to assess the influence of chemical weathering on sediment composition in this tropical basin. The abundance of clay minerals follows the rank order pattern of kaolinite > vermiculite > illite > smectite. Kaolinite is more abundant in river muds from the north-central than the southern Pantanal, suggesting strong extant chemical weathering plus the potential for clays inherited from siliciclastic parent lithologies that formed under Mesozoic greenhouse conditions. Illite occurs in sediments draining the North Paraguay Belt and limited parts of the South Paraguay Belt, and it reflects the influence of mechanical weathering of the metamorphic facies. In the southeastern Pantanal, vermiculite is a dominant constituent of the Miranda River watershed, which drains dacitic parent rocks and rhodic ferralsols. The geochemistry of the sediments reveals the interplay of quartz addition and clays inherited from the parent rocks. The most quartzose sediments are encountered at the confluence of the Paraguay River and the Taquari River megafan, where the cumulative effect of the 2 – 3-month flood pulse maximizes chemical weathering. Clay plus silt in back-bulge basins are controlled by climate > soils > parent rocks.
