Autor: Justin Nichols, Eric Joseph, Asmita Kaphle, Paige Tunby, Lina Rodríguez, Aashish Khandelwal, Justin Reale, Peter Regier, David J. Van Horn, Ricardo González-Pinzón

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-16 (2024)

Abstract Wildfire disturbance propagation along fluvial networks remains poorly understood. We use incident, atmospheric, and water-quality data from the largest wildfire in New Mexico’s history to quantify how this gigafire affected surface runoff

Microbial Community Responses to Increased Water and Organic Matter in the Arid Soils of the McMurdo Dry Valleys, Antarctica

Autor: Heather N Buelow, Ara S Kooser, David J Van Horn, John E Barrett, Michael N Gooseff, Egbert Schwartz, Cristina D Takacs-Vesbach

Publikováno v: Frontiers in Microbiology, Vol 7 (2016)

The soils of the McMurdo Dry Valleys, Antarctica are an extreme polar desert, inhabited exclusively by microscopic taxa. This region is on the threshold of anticipated climate change, with glacial melt, permafrost thaw, and the melting of massive bur

Factors Controlling Soil Microbial Biomass and Bacterial Diversity and Community Composition in a Cold Desert Ecosystem: Role of Geographic Scale.

Autor: David J Van Horn, M Lee Van Horn, John E Barrett, Michael N Gooseff, Adam E Altrichter, Kevin M Geyer, Lydia H Zeglin, Cristina D Takacs-Vesbach

Publikováno v: PLoS ONE, Vol 8, Iss 6, p e66103 (2013)

Understanding controls over the distribution of soil bacteria is a fundamental step toward describing soil ecosystems, understanding their functional capabilities, and predicting their responses to environmental change. This study investigated the co

Development of a general protocol for rapid response research on water quality disturbances and its application for monitoring the largest wildfire recorded in New Mexico, USA

Autor: Paige Tunby, Justin Nichols, Asmita Kaphle, Aashish Sanjay Khandelwal, David J. Van Horn, Ricardo González-Pinzón

Publikováno v: Frontiers in Water, Vol 5 (2023)

Anthropogenic and natural disasters (e.g., wildfires, oil spills, mine spills, sewage treatment facilities) cause water quality disturbances in fluvial networks. These disturbances are highly unpredictable in space-time, with the potential to propaga

The understudied winter: Evidence of how precipitation differences affect stream metabolism in a headwater

Autor: Justin Nichols, Aashish Sanjay Khandelwal, Peter Regier, Betsy Summers, David J. Van Horn, Ricardo González-Pinzón

Publikováno v: Frontiers in Water, Vol 4 (2022)

Climate change is causing pronounced shifts during winter in the US, including shortening the snow season, reducing snowpack, and altering the timing and volume of snowmelt-related runoff. These changes in winter precipitation patterns affect in-stre

Linking Hydrobiogeochemical Processes and Management Techniques to Close Nutrient Loops in an Arid River

Autor: Kelsey Bicknell, Peter Regier, David J. Van Horn, Kelli L. Feeser, Ricardo González-Pinzón

Publikováno v: Frontiers in Water, Vol 2 (2020)

In this study, we explored opportunities to optimize food-energy-water (FEW) resources by closing nutrient loops in aridland rivers. We evaluated source and sink behavior of nitrogen as nitrate (NO3-N) in three connected channels associated with an i
