“…In this study, the root node consisted of all 100 plots (10 9 10 m) from each area. Each cluster defines a species assemblage, and the threshold values of environmental variables define an associated habitat type (Larsen and Speckman 2004;Punchi-Manage et al 2013;Rodrigues et al 2019). MRT analysis was performed using the rpart package (Therneau et al 2017).…”

“…It is generally well-understood that topographic or geographical gradients in climatic factors (such as mean annual temperature and precipitation) influence species diversity, structure and function of the forests over a large scale (Jucker et al 2018;Ali et al 2019), whereas edaphic factors (such as soil physical and chemical properties) did so at a local or fine scale (Chiang et al 2016;Ali et al 2018b). In this context, it is understandable that topographic, climatic and edaphic factors determine the habitats differentiation in forests (i.e., Wang et al 2016;Guo et al 2017), and hence may affect community composition, species richness, structure and functioning of the forests due to the heterogeneity of the available resources (Liu et al 2014;Guo et al 2017;Ali et al 2018aAli et al , b, 2019Rodrigues et al 2019). Determining how habitat differentiation can affect tree communities can also be quite relevant for the management and conservation of forests at a fine and local scale.…”

“…For instance, aboveground biomass stock, as a key ecosystem property, in tropical forests plays a vital role in the global carbon cycle (Lewis et al 2015;Anderson-Teixeira et al 2016) by sequestering carbon dioxide, the main contributor to the greenhouse effect (Anderson-Teixeira et al 2016). Several studies have shown that topographic factors (e.g., convexity, elevation and slope) can determine plant growth (Moeslund et al 2013), species distribution (Toledo et al 2012) and diversity patterns (Ali et al 2018a;Rodrigues et al 2019). As such, topography modulates the relationships between species diversity and ecosystem functioning in tropical forests (Ali et al 2019;Jucker et al 2018).…”

Evaluating the influences of fine-scale habitat heterogeneity on the composition, diversity, structure and functioning of forests is critical to understand how tropical forests will respond to climate change and devise forest management strategies that will enhance biodiversity conservation and aboveground biomass stock. Here, we hypothesized that topographic and soil factors determine fine-scale habitat differentiation, which in turn shape community composition, species richness, structure and aboveground biomass at the local scale in tropical forests. To test this hypothesis, we selected two areas (each 100 9 100 m) with contrasting fine-scale topographic conditions where all trees, palms and lianas with a diameter at breast height C 10 cm were tagged and identified to species. In each selected area, 100 subplots of 10 9 10 m were established. We mainly found that higher topographic variability caused higher habitat differentiation with changes in species composition and community structure, but did not change species richness. Our habitat-scale analyses indicated that, in the less heterogeneous area, the distribution of species was more uniform along a fine-scale topographical gradient with no variation in convexity, which induced changes in structure and aboveground biomass, but not in species richness. The nonsignificant relationship between species richness and aboveground biomass may be attributable to species redundancy or functional dominance. This study suggests that environmental filtering is a fundamental process for shaping community assembly and forest functioning along a local topographical gradient in tropical forests.

“…Besides describing the vegetation, many studies use phytosociological parameters to investigate patterns of distribution of a focal species between samples (KOUR & SHARMA, 2014; WHITFORD, 1949), the relationship of dominance within a vegetation community (JIBRIN et al, 2018;VILLA;NERI, 2019), or to investigate the set of species that have greater weight in the plant community structure, for ecological restoration, or for human use (MELI et al, 2014;SOLDATI et al, 2017).…”

“…Fixed induced by seasonally flood disturbance, where the species will establish themselves according to their tolerance; such as soil water saturation (Pott & Silva 2015). The habitat heterogeneity can allow to increase the number of coexisting species and therefore shapes the community assembly (Brown et al 2013, Rodrigues et al 2019a. Alternatively, disturbance can cause divergence in community composition (high β-diversity) by increasing habitat filtering across environmental gradients (Myers et al 2015, Villa et al 2018; for instance, the seasonal flooding in the Pantanal wetland regulates the seedlings richness and abundance of the seed bank (Bao et al 2014(Bao et al , 2017.…”

Topography and Seasonality Promotes Taxonomic Beta Diversity of Seedlings in a Tropical Wetland

Spatial and temporal beta diversity of seedlings in tropical wetland remain poorly understood. We assessed the ecological pattern of taxonomic beta diversity of seedling assemblages along a topographic gradient, seasonally flooded disturbance, and sampling years in a tropical wetland. We tested that seasonally flooded disturbance on seedling assemblage promotes a high taxonomic beta diversity due to a high taxonomic turnover along the topographical gradient. Here we examined a large database from 200 plots (each having 0.5 × 0.5 m), across eight seasonally flooded grasslands in the Pantanal of central-west Brazil. We selected data on ponds for four years at two characteristic hydrological phases per year: post-flood (July and August), and post-dry season (October and November). We classified the topographical gradient into three levels 1) low-longer duration of flood; 2) mid-intermediate level; and 3) high-short duration of flood (dry soil). For both post-flood and post-dry seasons, we counted the number of seedlings within five plots at each topographic level. Additionally, taxonomic beta diversity was examined via novel abundance-based metrics (including both turnover and nestedness patterns). Overall, taxonomic beta diversity was consistently higher in high topographic level and post-dry season plots. We observed differences in beta diversity components between topographical levels, seasons and years. Topographical gradient and seasonally flooded promotes more variation in taxonomic turnover and beta diversity; due to these environmental filters we presume that the resulting beta diversity can be decisive in the species diversity in this tropical wetland.
