“…Environmental variables at habitat scale played more important roles over landscape and spatial factors for both taxonomic and functional diversity. This was understandable because the streams in our study covered a wide range of environmental gradients in which the environmental variation or habitat harshness in these systems provided a large scope for environmental filtering (Liu et al, ). In view of the above‐mentioned facts, it was thus surprising that the variation of phylogenetic diversity was more strongly explained by spatial factors rather than environmental variables.…”

“…Our results suggest that nutrients, conductivity, pH and chlorophyll‐ a (indicating the biomass of the whole algal community and, therefore, a trophic gradient) are important environmental variables that drive the diatom community. Nutrients, especially nitrogen and phosphorus, have been reported as the main environmental factors structuring diatom communities in temperate lakes (Blanco et al., ) and in tropical streams (Liu et al., ; Mangadze et al., ). The vertical distribution of nutrients, mediated by water‐column stability, can be an important factor that drives phytoplankton communities (Fonseca & Bicudo, ; Reynolds, ).…”

“…Streams are organised hierarchically in the landscape, within which environmental factors operate at a range of spatial scales (Frissell, Liss, Warren, & Hurley, ; Leps, Tonkin, Dahm, Haase, & Sundermann, ; Mykrä, Heino, & Muotka, ), directly or indirectly affecting the structure and composition of biological assemblages (Macedo et al., ; Sandin & Johnson, ; Townsend, Dolédec, Norris, Peacock, & Arbuckle, ). Therefore, assessing spatial patterns is essential for a comprehensive understanding of the drivers that determine the structural and functional diversity of stream assemblages (Heino, Muotka, & Paavola, ; Hoeinghaus, Winemiller, & Birnbaum, ; Liu et al., ; Macedo et al., ; Sandin & Johnson, ).…”
