“…Metacommunity theory has been widely used to explain the distribution patterns of many groups, such as fishes (Palheta et al, 2021; Vieira et al, 2020), bats (Bogoni et al, 2022; Presley & Willig, 2010), invertebrates (Cunha & Juen, 2020; Tonkin et al, 2015) and plants (González‐Caro et al, 2021; Oliveira et al, 2018). Despite the important contributions of this theory to understanding the organisation of biological communities, most metacommunity studies are focused on discrete archetypes which ignore the existence of numerous processes implicit to them (e.g., niche breadth and species interactions) (Thompson et al, 2020).…”

Metacommunity theory seeks to explain how local and regional processes contribute to the organisation of biological communities. Recent conceptual frameworks of this theory indicate that the dynamics of populations and communities are jointly established by dispersal, species responses to environmental conditions and biotic interactions dependent on species density. Here, we use hierarchical joint species distribution modelling to verify the effects of environmental factors (at multiple spatial scales), drainage network configuration, spatial autocorrelation and interspecific interactions on the structure of fish assemblages in terra‐firme streams in the Eastern Brazilian Amazon. Thirty streams were sampled in two field surveys, and 89 species were collected in total. Our results confirm the effects of limited dispersal, environmental conditions (at multiple scales) and the configuration of the drainage network on the dynamics of these assemblages. Furthermore, our results suggest that interspecific interactions are less relevant for the structuring of fish metacommunities in small Amazonian headwater streams. Abiotic factors like drainage networks and environmental heterogeneity were better predictors of species distributions than co‐occurrence patterns with potential competitors or predators.

“…Coherence relates to how species responds to the same environmental gradient, the range turnover re ects how community composition varies along the gradient, and range boundary clumping indicates the degree to which species range boundaries occur together (Leibold & Mikkelson, 2002;. Using the EMS framework, previous studies have identi ed a series of idealized metacommunity patterns in both terrestrial and aquatic ecosystems (Alahuhta & Heino, 2013;Bonthoux & Balent, 2015;Heino et al, 2015c;Vieira et al, 2020). However, the best-t species distribution modals for a given metacommunity are largely context dependent and usually showed distinct patterns with regard to organisms, spatial scale, and environmental gradients (Erős et al, 2017;Tonkin et al, 2016).…”

Biological communities exhibit multiple distribution patterns at metacommunity scale and assessing the major drivers of these patterns is a key issue in community ecology. Here we aimed to investigate how the environmental and geographic gradients shape the distribution patterns of macrophytes at metacommunity level.We applied the framework of the elements of metacommunity structure (EMS) to identify the distinct types of 48 macrophyte metacommunities in the Hengduan Mountain Region (HDMR) of China. Then we used generalized linear model and model selection approaches to determine which variables contributed to the variations of EMS, and linear discriminant function analysis to evaluate how well the tested variables in predicting the metacommunity patterns.We found wide variations of the three elements of metacommunity structure (i.e., coherence, range turnover, and range boundary clumping). Latitude and alpha diversity were most important in determining coherence, nestedness followed by spatial extent was mostly related to turnover, while sampling depth was signi cantly associated with boundary clumping. Seven metacommunity types were identi ed in HDMR and most metacommunities tted best the Gleasonian (continuous community boundaries) and Clementsian (discrete community boundaries) patterns as well as their quasi-structures. These metacommunity types were best discriminated by nestedness, altitude, and latitude. Our results provide strong evidences of the impact of geographic patterns on macrophyte metacommunities, with the Gleasonian patterns being dominant at the two ends of latitude/altitude gradients and the Clementsian patterns being common in the middle of the gradients.

Riverine ecosystems exhibit significant spatial variations in their communities, and understanding of these variances is vital to comprehend the mechanisms that maintain biodiversity. This study was conducted to understand pattern of distribution and beta diversity of fish communities in the Bhima River basin in the Deccan Plateau region of India. Fish distribution data from 59 sites across 11 rivers of the Bhima River basin were collected, and pair‐wise βDissimilarity and site‐wise local contribution to beta diversity (LCβDSorensen) and its components (LCβDTurnover and LCβDNestedness) were calculated. Power function regression was analysed to understand the decay in community similarity with geographical and environmental distances. Redundancy analysis was performed to investigate the relationship between fish distribution and environmental variables. Results indicated that species richness declined with increasing longitude from west to east. A negative relationship was observed between species richness and LCβDSorensen. LCβDTurnover formed Ո‐shaped curve at both ends of the species richness gradient, while LCβDNestedness values exhibited Ս‐shaped curve. No significant difference between mean LCβDTurnover and mean LCβDNestedness across the sites was observed. The distance decay relationship between community similarity and both geographical and environmental distances follows the power law shape, and the slope of this relationship flattened with increasing distance. Precipitation, topography, temperature variation and dissolved oxygen played a pivotal role in shaping fish assemblages. This study provides insight into the spatial distribution of fish communities in the Bhima River basin, which will be helpful to comprehend the ordination of biodiversity in the riverine ecosystem of the Deccan Plateau region.
