Utilizing artificial nesting platforms as a management tool: Enhancing breeding productivity of Western Flycatchers (Empidonax difficilis occidentalis) in southwestern Colorado and southern Arizona, USA
Charles van Riper III, Harold F. Greeney, Abigail J. Darrah, Andrew J. Boyce, Drew F. van Riper, Charles Yackulic
2024, Journal of Field Ornithology (95)
Artificial nesting substrates have been added around the world for many cavity-nesting bird species, but this has not been undertaken as extensively for crevice-nesting birds. The Western Cordilleran Flycatcher (Empidonax difficilis occidentalis) is a migratory, crevice-nesting flycatcher that is nest-site limited, breeding in higher elevation riparian habitats throughout intermountain western...
Innovation in climate adaptation: Harnessing innovation for effective biodiversity and ecosystem adaptation

2024, Report
Climate change poses growing risks to species, ecosystems, and people, and is challenging many of the assumptions that underpin modern conservation practice. As climate impacts accelerate, conventional conservation approaches are being compromised and losing their effectiveness. As a result, there is an urgent need to not only center climate adaptation...
Twenty years of explosive-effusive activity at El Reventador volcano (Ecuador) recorded in its geomorphology
Silvia Vallejo Vargas, Angela K. Diefenbach, Elizabeth Gaunt, Marco Almeida, Patricio Ramon, Fernanda Naranjo, Karim Kelfoun
2024, Frontiers in Earth Science (11)
Shifts in activity at long-active, open-vent volcanoes are difficult to forecast because precursory signals are enigmatic and can be lost in and amongst daily activity. Here, we propose that crater and vent morphologies, along with summit height, can help us bring some insights into future activity at one...

Afua Owusu, Stefanie Bohms, Mansoor Leh, Naga Manohar Velpuri, Murali Krishna Gumma, Benjamin Ghansah, Paranamana Thilina-Prabhath, Komlavi Akpoti, Kirubel Mekonnen, Primrose Tinonetsana, Ismail Mohammed
2024, International Journal of Applied Earth Observation and Geoinformation (126)
Agriculture consumes the largest share of freshwater globally; therefore, distinguishing between rainfed and irrigated croplands is essential for agricultural water management and food security. In this study, a framework incorporating the Budyko model was used to differentiate between rainfed and irrigated...

Application of lidar to assess the habitat selection of an endangered small mammal in an estuarine wetland environment
J.S. Hagani, J.Y. Takekawa, S.M. Skalos, Michael L. Casazza, M.K. Riley, S.A. Estrella, L. Barthman-Thompson, K.R. Smith, Kevin J. Buffington, Karen M. Thorne
2024, Ecology and Evolution (14)
Light detection and ranging (lidar) has emerged as a valuable tool for examining the fine-scale characteristics of vegetation. However, lidar is rarely used to examine coastal wetland vegetation or the habitat selection of small mammals. Extensive anthropogenic modification has threatened the endemic species in...

Farshid Felfelani, Joseph D. Hughes, Fei Chen, Aubrey L Dugger, Timothy Schneider, David Gochis, Jonathan P. Traylor, Hedeff I. Essaid
2024, Journal of Hydrology (630)
There is growing interest in incorporating higher-resolution groundwater modeling within the framework of large-scale land surface models (LSMs), including processes such as three-dimensional flow, variable soil saturation, and surface water/groundwater interactions. Conversely, complex groundwater models (e.g., the U.S. Geological Survey...

Rajagopalan Rengarajan, Michael J. Choate, Md Nahid Hasan, Alex Denevan
2024, Remote Sensing of Environment (301)
Landsat orthorectified products use Ground Control Points (GCPs) and Digital Elevation Models (DEM) to improve the geolocation accuracy and temporal consistency, and to account for the relief displacements due to the sensor-target geometry. In Collection-2, to improve the geometric harmonization between Landsat and...

2024, Avian Conservation and Ecology (19)
Forest thinning on public lands in the Pacific Northwest USA is an important tool for restoring diversity in forest stands with a legacy of simplified structure from decades of intensive management for timber production. A primary application of thinning in young (< 50-year-old) stands is to accelerate forest development to...
Isolation and identification of microcystin-degrading bacteria in Lake Erie source waters and drinking-water plant sand filters
Donna S. Francy, Jessica R. Cicale, Erin A. Stelzer, Dane C. Reano, Christopher D. Ecker
2024, Scientific Investigations Report 2023-5137
The increasing prevalence of cyanobacterial harmful algal blooms and the toxins they produce is a global water-quality issue. In the Western Basin of Lake Erie, high microcystin concentrations have led to water-quality advisories, process adjustments for treating drinking water, and increased water-quality monitoring. Biodegradation is an environmentally friendly and cost-effective...
Methods of analysis—Determination of pesticides in filtered water and suspended sediment using liquid chromatography- and gas chromatography-tandem mass spectrometry
Michael S. Gross, Corey J. Sanders, Matthew D. De Parsia, Michelle L. Hladik
2024, Techniques and Methods 5-A12
The widespread application of pesticides in agricultural and urban areas leads to their presence in surface waters. Presence of these biologically active chemicals in environmental waters potentially has adverse effects on nontarget organisms. To better understand the environmental fate of these contaminants, a robust method to capture chemicals with wide-ranging...
Short-term sediment dispersal on a large retreating coastal river delta via 234Th and 7Be sediment geochronology: The Mississippi River Delta Front
Andrew Courtois, Samuel J. Bentley, Jillian Maloney, Kehui Xu, Jason Chaytor, Ioannis Y. Georgiou, Michael Miner, Jeffery Obelcz, Navid H. Jafari, Melanie Damour
2024, Water (16)
Many Mississippi River Delta studies have shown recent declines in fluvial sediment load from the river and associated land loss. In contrast, recent sedimentary processes on the subaqueous delta are less documented. To help address this knowledge gap, multicores were collected offshore from the three main river outlets at water...

2024, PLoS ONE (19)
Wildlife conservation strategies focused on one season or population segment may fail to adequately protect populations, especially when a species’ habitat preferences vary among seasons, age-classes, geographic regions, or other factors. Conservation of golden eagles (Aquila chrysaetos) is an example of such a complex scenario, in...
Streamflow permanence in Mount Rainier National Park, Washington
Kristin Jaeger
2024, Fact Sheet 2023-3051
IntroductionStreams that flow throughout summer (“permanent” streams) provide critical habitat for aquatic species and serve as an important water supply. Streams that go dry seasonally or only flow after rainfall or snowmelt are a natural feature of mountain systems, including Mount Rainier National Park. However, in years with substantially less...

Eggshell thickness and egg morphometrics in five songbird species from the Central Valley, California
Carley R. Schacter, Sarah H. Peterson, C. Alex Hartman, Mark P. Herzog, Josh T. Ackerman
2024, Journal of Field Ornithology (95)
Avian eggshell thickness is an important life history metric in birds and has broad applications across disciplines ranging from animal behavior to toxicology. Empirical eggshell thickness values for songbirds (Order Passeriformes) are under-represented in the literature due to the difficulty of measuring smaller eggs using traditional methods. We used a...

Mapping Arundo donax (Arundo cane) with multispectral imagery before, during, and after herbicide treatment along the Rio Grande in Webb County, Texas, 2020–21
Jennifer Villa
2024, Scientific Investigations Map 3512
Arundo donax, commonly called Arundo cane, giant reed, or Carrizo cane, is an invasive bamboo-like perennial grass common in riparian areas throughout the southwestern United States. In Texas, not only does it negatively affect riparian ecosystems, but it has also become a problem for border security because it reduces visibility...
