Extent, patterns, and drivers of hypoxia in the world's streams and rivers

Autor: Joanna R. Blaszczak, Lauren E. Koenig, Francine H. Mejia, Lluís Gómez‐Gener, Christopher L. Dutton, Alice M. Carter, Nancy B. Grimm, Judson W. Harvey, Ashley M. Helton, Matthew J. Cohen

Publikováno v: Limnology and Oceanography Letters, Vol 8, Iss 3, Pp 453-463 (2023)

Abstract Hypoxia in coastal waters and lakes is widely recognized as a detrimental environmental issue, yet we lack a comparable understanding of hypoxia in rivers. We investigated controls on hypoxia using 118 million paired observations of dissolve

Classifying freshwater salinity regimes in central and western U.S. streams and rivers

Autor: Lauren A. Bolotin, Betsy M. Summers, Philip Savoy, Joanna R. Blaszczak

Publikováno v: Limnology and Oceanography Letters, Vol 8, Iss 1, Pp 103-111 (2023)

Abstract Freshwater salinization of rivers is occurring across the globe because of nonpoint source loading of salts from anthropogenic activities such as agriculture, urbanization, and resource extraction that accelerate weathering and release salts

Engineered headwaters can act as sources of dissolved organic matter and nitrogen to urban stream networks

Autor: Megan L. Fork, Joanna R. Blaszczak, Joseph M. Delesantro, James B. Heffernan

Publikováno v: Limnology and Oceanography Letters, Vol 3, Iss 3, Pp 215-224 (2018)

Abstract Improved management of urban stream water quality requires identification of sources contributing excess nutrients and organic matter. While soils and lawns are potential nonpoint sources characterized by large pools of carbon (C) and nitrog

The Microbiome Stress Project: Toward a Global Meta-Analysis of Environmental Stressors and Their Effects on Microbial Communities

Autor: Jennifer D. Rocca, Marie Simonin, Joanna R. Blaszczak, Jessica G. Ernakovich, Sean M. Gibbons, Firas S. Midani, Alex D. Washburne

Publikováno v: Frontiers in Microbiology, Vol 9 (2019)

Microbial community structure is highly sensitive to natural (e.g., drought, temperature, fire) and anthropogenic (e.g., heavy metal exposure, land-use change) stressors. However, despite an immense amount of data generated, systematic, cross-environ

Models of underlying autotrophic biomass dynamics fit to daily river ecosystem productivity estimates improve understanding of ecosystem disturbance and resilience

Autor: Joanna R. Blaszczak, Charles B. Yackulic, Robert K. Shriver, Robert O. Hall

Directly observing autotrophic biomass at ecologically relevant frequencies is difficult in many ecosystems, hampering our ability to predict productivity through time. Since disturbances can impart distinct reductions in river productivity through t

Pervasive changes in stream intermittency across the United States

Publikováno v: Environmental Research Letters, Vol 16, Iss 8, p 084033 (2021)

Non-perennial streams are widespread, critical to ecosystems and society, and the subject of ongoing policy debate. Prior large-scale research on stream intermittency has been based on long-term averages, generally using annually aggregated data to c

What’s in a Name? Patterns, Trends, and Suggestions for Defining Non-Perennial Rivers and Streams

Publikováno v: Water, Vol 12, Iss 7, p 1980 (2020)

Rivers that cease to flow are globally prevalent. Although many epithets have been used for these rivers, a consensus on terminology has not yet been reached. Doing so would facilitate a marked increase in interdisciplinary interest as well as critic
