“…Further, some substantial differences in ecological requirements were predicted by the SDMs of elmid genera in the current research ( Figure 4 ). These differences are like previous studies [ 16 , 22 , 115 , 116 ], which found that genera in the Elmidae family differ regarding their ecological requirements. In this context, despite some relevant works that have been published on the taxonomy of the Ecuadorian Elmidae in the last few years [ 117 , 118 , 119 ], no work has been done about species distribution modelling of Elmidae.…”

Genera and species of Elmidae (riffle beetles) are sensitive to water pollution; however, in tropical freshwater ecosystems, their requirements regarding environmental factors need to be investigated. Species distribution models (SDMs) were established for five elmid genera in the Paute river basin (southern Ecuador) using the Random Forest (RF) algorithm considering environmental variables, i.e., meteorology, land use, hydrology, and topography. Each RF-based model was trained and optimised using cross-validation. Environmental variables that explained most of the Elmidae spatial variability were land use (i.e., riparian vegetation alteration and presence/absence of canopy), precipitation, and topography, mainly elevation and slope. The highest probability of occurrence for elmids genera was predicted in streams located within well-preserved zones. Moreover, specific ecological niches were spatially predicted for each genus. Macrelmis was predicted in the lower and forested areas, with high precipitation levels, towards the Amazon basin. Austrelmis was predicted to be in the upper parts of the basin, i.e., páramo ecosystems, with an excellent level of conservation of their riparian ecosystems. Austrolimnius and Heterelmis were also predicted in the upper parts of the basin but in more widespread elevation ranges, in the Heterelmis case, and even in some areas with a medium level of anthropisation. Neoelmis was predicted to be in the mid-region of the study basin in high altitudinal streams with a high degree of meandering. The main findings of this research are likely to contribute significantly to local conservation and restoration efforts being implemented in the study basin and could be extrapolated to similar eco-hydrological systems.

“…2). Считается, что бурное течение горных водотоков способствует насыщению воды кислородом и создает благоприятные условия для дыхания гидробионтов (Chapman et al 2004;García-Ríos et al 2020;Rico-Sánchez et al 2022). Кроме этого, снижение температуры воды повышает растворимость газов, что также ведет к увеличению концентрации кислорода в воде (Xing et al 2014)…”

With an increase in altitude, both abiotic and biotic conditions in mountain watercourses change. To assess the features of spatial distribution of macroinvertebrates as well as to identify the driving factors of this dynamics, the data on species richness, abundance and biomass of EPT taxa (mayfly, stonefly, caddisfly) from 21 small mountain rivers of Altai were analyzed. By location, all rivers were divided into 4 groups: the ones running in the low-mountain (<1000 m asl) zone, in the low (1000–1500) and upper (1500–2000) parts of the middle mountains and in the high-mountain (>2000 m asl) zone. A total of 71 EPT macroinvertebrate taxa were recorded in the studied streams. Species richness (according to the average species number per sample) as well as abundance and biomass of macroinvertebrates decreased with an increase in altitude. The maximum variance in structural indicators of communities appeared due to the combined influence of the location of the altitudinal zone and phytoplankton development level (estimated by the content of chlorophyll a). At the same time, categorical predictors (both abiotic and biotic) included in the analysis better explained the variability of diversity-related indicators than that of abundance and biomass. When developing the environmental monitoring programs for mountain watercourses, the identified trends in reduction (with altitude) of species richness of macroinvertebrate taxa responsible for the formation of taxonomically poor and strongly vulnerable communities in high-altitude areas should be taken into account.
