Lessons learned in applying decision analysis to natural resource management for high stakes issues surrounded by uncertainty Lessons learned in applying decision analysis to natural resource management for high stakes issues surrounded by uncertainty
Management agencies are tasked with difficult decisions for conservation and management of natural resources. These decisions are difficult because of ecological and social uncertainties, the potential for multiple decision makers from multiple jurisdictions, and the need to account for the diverse values of stakeholders. Decision analysis provides a framework for accounting for these...

Lessons learned from community and citizen science monitoring projects on the Elwha River Restoration Project Lessons learned from community and citizen science monitoring projects on the Elwha River Restoration Project
Community and citizen science (CCS) projects – initiatives that involve public participation in scientific research – can both sustain and expand long-term monitoring of large dam removal projects. In this article, we discuss our perspectives on CCS associated with the Elwha River dam removals. We summarize how the public has been or could be involved in monitoring and distill lessons...

Synergistic behavioral antagonists of a sex pheromone reduce reproduction of invasive sea lamprey Synergistic behavioral antagonists of a sex pheromone reduce reproduction of invasive sea lamprey
Sex pheromones impart maximal attraction when their components are present at optimal ratios that confer balanced olfactory inputs in potential mates. Altering ratios or adding pheromone analogs to optimal mixtures may disrupt balanced olfactory antagonism and result in reduced attraction, however, tests in natural populations are lacking. We tested this hypothesis in sea lamprey...

Crop water use dynamics over arid and semi-arid croplands in the lower Colorado River Basin Crop water use dynamics over arid and semi-arid croplands in the lower Colorado River Basin
Numerous studies have evaluated the application of Remote Sensing (RS) techniques for mapping actual evapotranspiration (ETa) using Vegetation-Index-based (VI-based) and surface energy balance methods (SEB). SEB models computationally require a large effort for application. VI-based methods are fast and easy to apply and could therefore potentially be applied at high resolution; however...

Long-term trends of local bird populations based on monitoring schemes: Are they suitable for justifying management measures? Long-term trends of local bird populations based on monitoring schemes: Are they suitable for justifying management measures?
Local biodiversity monitoring is important to assess the effects of global change, but also to evaluate the performance of landscape and wildlife protection, since large-scale assessments may buffer local fluctuations, rare species tend to be underrepresented, and management actions are usually implemented on local scales. We estimated population trends of 58 bird species using open...

Evidence for fine-grained material at lunar red spots: Insights from thermal infrared and radar data sets Evidence for fine-grained material at lunar red spots: Insights from thermal infrared and radar data sets
Lunar red spots are small spectrally red features that have been proposed to be the result of non-mare volcanism. Studies have shown that a number of red spots are silicic, and are spectrally distinct from both highlands and mare compositions. In this work, we use data from LRO Diviner, Mini-RF, and Arecibo to investigate the material properties of 10 red spots. We create albedo maps...

Eruption of stagnant lava from an inactive perched lava lake Eruption of stagnant lava from an inactive perched lava lake
Lava flow hazards are usually thought to end when the erupting vent becomes inactive, but this is not always the case. At Kīlauea in August 2014, a spiny ʻaʻā flow erupted from the levee of a crusted perched lava lake that had been inactive for a month, and the surface of the lava lake subsided as the flow advanced downslope over the following few days. Topography constructed from...

Expansive, positive changes to fish habitat diversity following the formation of a valley plug in a degraded desert river Expansive, positive changes to fish habitat diversity following the formation of a valley plug in a degraded desert river
Widespread hydrologic alterations have simplified in-stream habitats in rivers globally, driving population declines and extirpations of many native fishes. Here, we examine how rapid geomorphic change in a historically degraded desert river has influenced habitat diversification and ecosystem persistence. In 2010, a large reach of the degraded and simplified lower San Rafael River (SRR)...

Doing the same thing over and over again and getting the same result: Assessing variance in wetland invertebrate assemblages Doing the same thing over and over again and getting the same result: Assessing variance in wetland invertebrate assemblages
Past efforts to explain variation of invertebrate assemblages in freshwater wetlands have been less productive than anticipated. To explore why efforts are disappointing, we assembled large invertebrate data sets from North Dakota prairie potholes, California rock pools, and Georgia Carolina bay wetlands that addressed spatial (among wetlands) and temporal (among seasons and years)...

The 50-year Landsat collection 2 archive The 50-year Landsat collection 2 archive
The Landsat global consolidated data archive now exceeds 50 years. In recognition of the need for consistently processed data across the Landsat satellite series, the U.S. Geological Survey (USGS) initiated collection-based processing of the entire archive that was processed as Collection 1 in 2016. In preparation for the data from the now successfully launched Landsat 9, the USGS...

Population dynamics of the threatened Oregon spotted frog before and after drought mitigation Population dynamics of the threatened Oregon spotted frog before and after drought mitigation
Amphibians are among the most sensitive taxa to climate change, and species inhabiting arid and semiarid landscapes at the extremes of their range are especially vulnerable to drought. The Jack Creek, Oregon, USA, population of Oregon spotted frogs (Rana pretiosa) faces unique challenges because it occupies the highest elevation site in the species' extant range and one that has been...

Rates of osmoconformation in triploid eastern oysters, and comparison to their diploid half-siblings Rates of osmoconformation in triploid eastern oysters, and comparison to their diploid half-siblings
Triploid eastern oysters (Crassostrea virginica) suffer greater mortalities than diploids in the U.S. Gulf of Mexico estuaries when extreme low salinities ( 5) and elevated temperatures (≥ 28 °C) coincide. To investigate potential causes, changes in plasma osmolality, hemolymph pH, valve opening and mortality in diploid and triploid oyster half-siblings were compared during a step-down...
