A model‐based assessment of anthropogenic disturbance on lotic macroinvertebrate assemblages Open
Traditionally, the effects of anthropogenic disturbance on biological assemblages are elucidated by comparing an assemblage observed at a site to one that represents a minimally disturbed state. Unfortunately, defining a minimally disturbe…

Quantifying form resistance is essential for estimating summer low and bankfull flow from stream survey channel morphology Open
Reliable estimates of low flow and flood discharge at ungaged locations are required for evaluating stream flow alteration, designing culverts and stream crossings, and interpreting regional surveys of habitat and biotic condition. Very fe…

Distribution and Characteristics of Blackwater Rivers and Streams of the Contiguous United States Open
Blackwater rivers and streams have stained or tea‐colored water from tannins released by decaying plant matter. Natural conditions in these waters often differ from non‐blackwater systems. For example, the pH and oxygen levels in waters ca…

Disentangling natural and anthropogenic effects on benthic macroinvertebrate assemblages in western <span>US</span> streams Open
Stream macroinvertebrate assemblages are shaped by natural and human‐related factors that operate through complex hierarchical pathways. Quantifying these relationships can provide additional insights into stream ecological assessment. We …

Habitat complexity mediates the impacts of human land-use on stream biodiversity Open
Urban and cropland intensifications are persistent drivers of declines in biodiversity globally. Yet, it is poorly understood how habitat complexity can mitigate the negative impacts of such human pressures. Using a comprehensive dataset o…

Joint species distribution models reveal taxon-specific sensitivities to potential anthropogenic alteration Open
Taxon-environment relationships can elucidate a taxon's tolerance or sensitivity to specific environmental conditions. We use a joint species distribution modeling framework to quantify relationships between ~1700 benthic macroinvertebrate…

Wood predictors in neotropical streams: Assessing the effects of regional and local controls in Amazon and Cerrado catchments Open
Large wood plays a critical role providing complex habitat structure in rivers and streams. The instream wood regime consists of wood recruitment, transport, retention, and decay in river corridors. In tropical streams, transport and decay…

Wood stock in neotropical streams: Quantifying and comparing instream wood among biomes and regions Open
Instream wood plays important chemical, physical and ecological functions in aquatic systems, benefiting biota directly and indirectly. However, human activities along river corridors have disrupted wood recruitment and retention, usually …

Physical habitat in conterminous US streams and Rivers, part 2: A quantitative assessment of habitat condition Open
Rigorous assessments of the ecological condition of water resources and the effect of human activities on those waters require quantitative physical, chemical, and biological data. The U.S. Environmental Protection Agency's river and strea…

Physical habitat in conterminous US streams and rivers, Part 1: Geoclimatic controls and anthropogenic alteration Open
Anthropogenic alteration of physical habitat structure in streams and rivers is increasingly recognized as a major cause of impairment worldwide. As part of their assessment of the status and trends in the condition of rivers and streams i…

Natural and anthropogenic controls on lake water‐level decline and evaporation‐to‐inflow ratio in the conterminous United States Open
Lake water levels are integral to lake function, but hydrologic changes from land and water management may alter lake fluctuations beyond natural ranges. We constructed a conceptual model of multifaceted drivers of lake water levels and ev…
