Ian R Waite
Ian Waite has been an aquatic ecologist in the USGS Oregon Water Science Center since June 1992.
Research Focus My primary focus has been on understanding the effects of multiple instream stressors in wadeable streams on biological assemblages (diatoms, macroinvertebrates, fish) throughout the U.S., primarily looking at the effects of agriculture and urban land use.
One of my specialties is the use of multivariate statistics and various modeling techniques (e.g., machine learning, predictive, etc.) to help us untangle the complex mixture of natural and anthropogenic variables at diverse spatial scales (e.g., instream, local, watershed and regional) that are effecting stream ecosystems.
I've been applying various predictive modeling approaches to better understand the causal mechanisms of disturbance on aquatic ecosystems across a large diversity of ecosystems and scales. I collaborate with other federal agencies, Indian tribes, State and non-profit groups and I am increasingly working with international researchers to better understand and improve our ability to manage aquatic ecosystems. I work to communicate the findings through public meetings, watershed councils, international science conferences and in journal publications.
I feel I can analyze, develop models and summarize almost any type of data and present the findings in a clear concise manner.

Multiple lines of evidence point to pesticides as stressors affecting invertebrate communities in small streams in five United States regions
Target and suspect per- and polyfluoroalkyl substances in fish from an AFFF-impacted waterway
Field assessment of Naled and its primary degradation product (dichlorvos) in aquatic ecosystems following aerial ultra-low volume application for mosquito control
Framework for the development of the Columbia River mainstem fish tissue and water quality monitoring program - Bonneville Dam to Canadian border
Identifying monitoring information needs that support the management of fish in large rivers
Capacity assessment for Earth Monitoring, Analysis, and Prediction (EarthMAP) and future integrated monitoring and predictive science at the U.S. Geological Survey
Multiple in-stream stressors degrade biological assemblages in five U.S. regions
Multi-region assessment of chemical mixture exposures and predicted cumulative effects in USA wadeable urban/agriculture-gradient streams
Chemical-contaminant mixtures are widely reported in large stream reaches in urban/agriculture-developed watersheds, but mixture compositions and aggregate biological effects are less well understood in corresponding smaller headwaters, which comprise most of stream length, riparian connectivity, and spatial biodiversity. During 2014–2017, the U.S. Geological Survey (USGS) measured 389 unique orga
Understanding the relationship between stream metabolism and biological assemblages
Legacy and current‐use contaminants in sediments alter macroinvertebrate communities in southeastern US Streams
Assessment of multi-stressors on compositional turnover of diatom, invertebrate and fish assemblages along an urban gradient in Pacific Northwest streams (USA)
Projected urban growth in the Southeastern USA puts small streams at risk
