Abstract We examined how communities of macroinvertebrates occurring in functional process zones (FPZs) are affected by the location FPZs river continuum. delineated for three rivers displaying significant disparities elevation, annual precipitation, valley shape, and other valley‐scale hydrogeomorphic variables. extracted corresponding macroinvertebrate community data from US National Water Quality Monitoring Council database matched it to stream order (SO) FPZ delineations. structure...
We assessed the potential influence of hydrological connectivity among subdrainages on structural and functional organization stream macroinvertebrate metacommunities in 2 adjacent, large Asian watersheds (~1.4 million km2). To examine metacommunities, we used multisite β-diversity partitioning applied Elements Metacommunity Structure (EMS) framework to resolve aspects taxon associations metacommunity assembly. also decomposed β diversity into nestedness turnover assess contrasting...
The dissolved oxygen diel cycle is an inherent feature of stream ecosystems, and the amplitude in this fluctuation thought to strongly influence composition communities. For instance, extremely low saturation (DDO) values have well-documented effects on macroinvertebrates. Less known, however, about subtler differences assemblages. In study, we examined if variation DDO streams associated with changes taxonomic trait macroinvertebrate We assemblages 3 drainages Great Basin USA covering a...
Abstract The introduction of nonnative species is one the most critical problems facing freshwater systems today. rivers Great Basin (USA) have been particularly imperilled by introductions and represent a valuable location to study dietary trends native fishes in isolated, endorheic systems. We collected fish from 23 sites, spanning three watersheds (Carson, Humboldt Bear Rivers) two elevation categories (upland lowland). Only single (speckled dace Rhinichthys osculus ) occurred both zones....
Streams in the Mongolian Altai Mountains are mostly fed from glaciers and extreme conditions for mayflies because of high elevation, low temperatures annual precipitation. Previous information about Western Mongolia is scarce, but with this study a total 38 species belonging to 26 genera subgenera 8 families has been recorded region. Study material was entirely imagos collected 78 sites during expeditions led by Aquatic Insect Survey 2008, 2009 2010. Raptobaetopus tenellus, Caenis luctuosa...
Abstract The invasion of freshwater ecosystems by non‐native species can constitute a significant threat to native and ecosystem health. Non‐native trouts have long been stocked in areas where occur negatively impacted through predation, competition, hybridization. This study encompassed two seasons sampling efforts across ecoregions the western United States: Great Basin summer 2016 Yellowstone River 2017. We found dietary overlaps among within ecoregions. Three orders invertebrates...
Current understanding of how streamflow in terminal basins is driven by climatic and hydrogeomorphic characteristics limited, despite the fact that these closed systems show an increased sensitivity to climate change terms increase demand for water resources. We examined patterns 2 major basins, Great Basin United States (US-TB) Central Asian Internal Drainage Mongolia (MN-TB). obtained daily flow data spanning 1990 2014 both established hydrological indices (HIs), selected a subset HIs best...
Lake Khuvsgul has low fish diversity due to its ultra-oligotrophic conditions and contains only 10 species. In this study, we examined stomachs of the endemic species, grayling (Thymallus nigrescens), compared a diet variation among populations inhabiting littoral pelagic zones. We collected samples from zones southwest, northwest, east shores using gill nets, preserved specimens their in 4% formalin. laboratory, weighed identified organisms at mostly order levels. then assessed abundances...
