“…Streams and rivers are among the most threatened ecosystems on the planet, with recent assessments showing extensive degradation around the globe (Feio et al 2022). Human activities such as agriculture are among the leading threats to stream health (Marrochi et al 2021;Pearce et al 2021;Arocena et al 2022;Champagne et al 2022) because they can have pervasive impacts on hydrology, water chemistry, habitat, and biological structure and function. Thus, clear evidence of how human activity affects freshwater ecosystems is needed for the development of management strategies that can protect and rehabilitate freshwaters.…”

Context Land use in a catchment area is critical to understanding how human activities are impacting streams. Catchment land cover is typically quantified as proportions of land use types, but such proportions do not quantify where land use patches are relative to the stream. Objectives This paper discusses the merit of land use position metrics for application to stream assessments. Methods and results Landscape configuration metrics (LCMs) are often used in stream assessments to describe land use position, but we argue these metrics should be avoided due to: (1) poor description of catchment land cover; (2) inconsistency, and; (3) missing link between valley and stream. Inverse-distance-weighted metrics (IDWs) explicitly quantify the position of land use patches relative to the stream, and thus are conceptually grounded in empirical evidence that the effect of land use is inversely related to its distance from the stream. Hydrologically active IDWs (HA-IDWs) further refine IDWs by quantifying the proximity of land use to hydrologic pathways connecting a stream to its catchment. Conclusions We recommend IDW metrics become the standard method to describe catchment land use and its effect on stream conditions and that HA-IDW metrics be used when the required data is available.

This study presents a comprehensive list of Chironomidae species recorded in Uruguay, compiled through a bibliographic review. A total of 41 genera of Chironomidae are documented, categorized into four subfamilies: Chironominae, Diamesinae, Orthocladiinae, and Tanypodinae. Additionally, genera lacking named species are included in the list, identified primarily through the analysis of larval characteristics, particularly from limnological investigations.
