2023, Environmental Software and Modelling (163)
Anthropogenic hydrologic alteration threatens the health of riverine ecosystems. Machine learning algorithms that employ the use of model trees to predict hydrologic alteration are underrepresented in related literature. This study assesses hydrologic alteration in the Pearl and Pascagoula River basins using modeled...
Increased salinity decreases annual gross primary productivity at a Northern California brackish tidal marsh
Sarah Russell, Lisamarie Windham-Myers, Ellen J Goodrich-Stuart, Brian A. Bergamaschi, Frank Anderson, Patty Oikawa, Sara Knox
2023, Environmental Research Letters (18)
Tidal marshes sequester 11.4–87.0 Tg C yr−1 globally, but climate change impacts can threaten the carbon capture potential of these ecosystems. Tidal marshes occur across a wide range of salinity, with brackish marshes (0.5–18 ppt (parts per thousand)) dominating global tidal marsh extents. A diverse mix of freshwater-...

Achieving this goal requires a complex intersection of...
Using DC resistivity ring array surveys to resolve conductive structures around tunnels or mine-workings
Michael Albert Mitchell, Douglas W. Oldenburg
2023, Journal of Applied Geophysics (211)
In underground environments, conventional direct current (DC) resistivity surveys with a single linear array of electrodes produce fundamentally non-unique inversions. These non-uniqueness and model resolution issues stem from limitations placed on the location of transmitters (TXs) and receivers (RXs) by the geometry of existing tunnels and boreholes. Poor excitation...
A river basin spatial model to quantitively advance understanding of riverine tree response dynamics to water availability and hydrological management
Tanya M. Doody, Sicong Gao, Willem Vervoot, Jodie Pritchard, Michah Davies, Martin Nolan, Pamela L. Nagler
2023, The Journal of Environmental Management (332)
Ecological condition continues to decline in arid and semi-arid river basins globally due to hydrological over-abstraction combined with changing climatic conditions. Whilst provision of water for the environment has been a primary approach to alleviate ecological decline, how to accurately monitor changes in riverine...
User’s Guide to planetary image analysis and geologic mapping in ArcGIS Pro
Sarah R. Black
2023, Techniques and Methods 11-B14
Geologic maps are valuable tools in planetary science. Though planetary geologic maps are similar to terrestrial (Earthbased) geologic maps, the nature of planetary exploration introduces unique challenges for geologic mappers. Terrestrial geologic mappers prepare products from field-based observation, often comparing or refining those with aerial and (or) orbital images. Planetary...

Nicholas E. Kichas, Gregory T. Pederson, Sharon M. Hood, Richard G. Everett, David B. McWethy
2023, Frontiers in Forests and Global Change (6)
Introduction: Tree defense characteristics play a crucial role in modulating conifer bark beetle interactions, and there is a growing body of literature investigating factors mediating tree growth and resin-based defenses in conifers. A subset of studies have looked at relationships between tree growth, resin duct morphology and climate; however, these...
Simulation of monthly mean and monthly base flow of streamflow using random forests for the Mississippi River Alluvial Plain, 1901 to 2018
Benjamin J. Dietsch, William H. Asquith, Brian Breaker, Stephen M. Westenbroek, Wade H. Kress
2023, Scientific Investigations Report 2022-5079
Improved simulations of streamflow and base flow for selected sites within and adjacent to the Mississippi River Alluvial Plain area are important for modeling groundwater flow because surface-water flows have a substantial effect on groundwater levels. One method for simulating streamflow and base flow, random forest (RF) models, was developed...
Distribution of northern long-eared bat summer-habitat derived from historical data collected on the Monongahela National Forest, West Virginia, USA
J.L. De La Cruz, W. Mark Ford, S. Beaux Jones, J.R. Johnson, A. Silvis
2023, Journal of the Southeastern Association of Fish and Wildlife Agencies (10) 114-124
Species distribution models enable resource managers to avoid and mitigate impacts to, or enhance habitat of, target species at the landscape level. Persistent declines of northern long-eared bats (Myotis septentrionalis) due to white-nose syndrome have made acquisition of contemporary data difficult. Therefore, use of legacy data may be necessary for creation...

Results of validation exercise for Marine Benthic Index
Valerie Partridge, Donald Schoolmaster
2023, Report
Marine benthic invertebrates (benthos) are key components of the Puget Sound ecosystem. Because of their direct association living in, and sometimes consuming, sediments, benthos can be valuable sentinels of ecosystem health. Therefore, indicators of benthic invertebrate community health can serve as direct measures of sediment and water quality. In 2021,...

Julien Martin, Matthew S. Richardson, Davina Passeri, Nicholas Enwright, Simeon Yurek, James Flocks, Mitchell J. Eaton, Sara Zeigler, Hadi Charkhgard, Bradley James Udell, Elise R. Irwin
2023, Ecology and Society (28)
The loss of ecosystem services due to climate change and coastal development is projected to have significant impacts on local economies and conservation of natural resources. Consequently, there has been an increase in coastal management activities such as living shorelines, oyster reef restoration, marsh restoration, beach and dune nourishment, and...
Unravelling the influence of landscape alteration from flow alteration on benthic macroinvertebrate assemblage response in the Delaware River Basin
Jonathan G. Kennen, Thomas F. Cuffney
2023, Ecohydrology (16)
Quantifying the effects of streamflow alteration on assemblage response is central to understanding the role humans play in shaping aquatic environments. These changes represent a level of complexity that impedes developing quantitative links between flow and ecological response because stream hydrology is strongly intertwined with natural and anthropogenic factors. Better...

Sheel Bansal, Max Post van der Burg, Rachel Fern, John Jones, Rachel Lo, Owen P. McKenna, Brian Tangen, Zhen Zhang, Robert A. Gleason
2023, Science Advances (9)
Natural methane (CH4) emissions from aquatic ecosystems may rise because of human-induced climate warming, although the magnitude of increase is highly uncertain. Using an exceptionally large CH4 flux dataset (~19,000 chamber measurements) and remotely sensed information, we modeled plot- and landscape-scale wetland CH4 emissions from the Prairie Pothole Region (PPR), North America’s...

2023, Climate Change (176)
Freshwater ecosystems, including lakes, streams, and wetlands, are responsive to climate change and other natural and anthropogenic stresses. These ecosystems are frequently hydrologically and ecologically connected with one another and their surrounding landscapes, thereby integrating changes throughout their watersheds. The responses of any given freshwater ecosystem...
