“…Positive SES.RaoQ values indicate that the species of a given habitat are functionally or phylogenetically more distant than expected by chance (overdispersed or divergent habitats), and negative SES.RaoQ values indicate that species are closer to one another than expected by chance (underdispersed or clustered habitats). To test the statistical significance of observed SES values with null expectation SES values, we used a two‐sided Wilcoxon signed rank test (Bernard‐Verdier et al, 2012; Nooten et al, 2021).…”

“…Improving biodiversity data is one effective way of addressing the influence of global change on biodiversity, ecological restoration, and species assemblages (GraÇA et al, 2017;Sańchez et al, 2021). Biodiversity in nature is a multi-dimensional property, including taxonomic (TD), phylogenetic (the degree of variety in species lineages; PD), and functional diversity (the degree of variety in species traits; FD) (Faith, 1992;Nooten et al, 2021). These complementary dimensions of biodiversity offer information on ecology and evolution associated with the species assemblages at the a and b diversity scales (Swenson, 2011;Mirochnitchenko et al, 2021).…”

Understanding the multifaceted plant diversity and its maintenance mechanisms is crucial for biodiversity conservation. Dam-induced water level fluctuations dramatically alter various aspects of riparian diversity, such as taxonomic (TD), phylogenetic (PD), or functional (FD) diversity. However, few studies simultaneously evaluated plant TD, FD, and PD, especially in the subtropical reservoir riparian zone. Here we sampled plant diversity and environmental drivers along inundation gradients of the Three Gorges Reservoir Region in China. We integrated multifaceted plant diversity to assess how distinct ecological processes affect the plant community assembly and how they respond to inundation gradients, spatial variability, climate, and soils in dam-regulated riparian zones. We found that alpha TD, PD, and FD diversity exhibited decreasing trends with increasing inundation gradients and significant positive correlations with soil organic matter. The number of clustering plant communities increases along the inundation gradients. Beta TD and PD diversity were mainly dominated by species turnover with fewer contributions from nestedness, while beta FD diversity was mainly dominated by nestedness with fewer contributions from species turnover. The explainable rates of different dimensions of beta diversity, turnover, and nestedness ranged from 11% to 61%, with spatial factors explaining the highest beta diversity in different dimensions, followed by inundation gradients, soil properties, and climate variables. Our results suggest dispersal limitations are more important for species turnover in dam-regulated riparian zones at regional scales, while inundation gradients and soil fertility are more critical in shaping plant community assemblages at the local scale. This study emphasizes that environmental and spatial gradients are critical for understanding the assembly mechanisms driving multifaceted plant communities at local and regional scales and reinforces the importance of protecting seed sources and dispersal pathways and maintaining river connectivity when implementing restoration projects.

“…Nevertheless, ants also include some of the globally notorious invasive species 15 , which allows one to examine the effect of invasive ants on the native ants and other elements of terrestrial invertebrate diversity.Urbanization has been shown to be associated with a change in composition and structure of native insects, dominance of certain generalist and invasive species, and invasion of invasive and alien species 24 . For ants, urbanization has been associated with a decrease [16][17][18] , no change 25 , or an increase [21][22][23]26 of species richness and abundance. In cities, natural forest fragments, semi-natural gardens, homeyards, well-managed botanical…”

“…Sacred groves-the relics of biodiversity-rich natural forests [27][28][29] have a higher ant diversity 25,30,31 . Although a good number of studies are in agreement that urbanization can change the characteristics of ant communities [16][17][18][19][20][21][22] and favour invasive ant species in urban green spaces 15,30,32,33 , Nooten et al 26 found that the sacred groves of urban Hong Kong encompass a higher richness of native and specialist ants, which are resilient to invasive species. Invasion of tramp or invasive species results in colonization and spill-over to neighbouring less-disturbed areas, where they might displace or affect the activities of native ants 15,30,32,33 .…”

Urbanization is a crucial driver of environmental and biodiversity change. It is suggested that urbanization favours generalist and invasive species and might harm specialists of natural and semi-natural habitats. In this study, we examined how an urbanization gradient and environmental gradients in the habitat area, habitat diversity, elevation, and proportion of built-up area influenced the abundance and richness of ants within tropical forest islet habitat in south India. We used abundance (proportional trap incidence) of overall ants, native ants, invasive ants, and Anoplolepis gracilipes—a globally notorious invasive ant of possible south Asian origin—and rarefied richness as the response variables. We found that native ant abundance was greater and A. gracilipes abundance was lesser in less-urbanized landscape compared to moderately-urbanized and highly-urbanized landscape. The richness of ants and abundance of overall and invasive ants were unaffected by the urbanization. We also found that none of the measured environmental gradients but habitat diversity influenced abundance of overall ants, native ants, overall invasive ants, and richness of ants; however, A. gracilipes abundance was negatively correlated with habitat diversity. Ant species composition of less-urbanized landscape was distinct from that of higher urbanization levels. The richness and abundance of native ants and abundance of non-A. gracilipes invasive ants decreased with the abundance of A. gracilipes. Because the forest islets of all three urbanization levels supported similar richness of native ants, the urbanization seems not to have an adverse effect for the native ants of native forest islets. The increasing population of A. gracilipes in urban green islets, however, is a concern. Future studies might investigate its effect on other invertebrates of epigeal and soil strata.
