Incorporating environmental heterogeneity and observation effort to predict host distribution and viral spillover from a bat reservoir Incorporating environmental heterogeneity and observation effort to predict host distribution and viral spillover from a bat reservoir
Predicting the spatial occurrence of wildlife is a major challenge for ecology and management. In Latin America, limited knowledge of the number and locations of vampire bat roosts precludes informed allocation of measures intended to prevent rabies spillover to humans and livestock. We inferred the spatial distribution of vampire bat roosts while accounting for observation effort and

Implementing a dual-spectrometer approach for improved surface reflectance estimation Implementing a dual-spectrometer approach for improved surface reflectance estimation
Surface reflectance measurement is an integral part of the vicarious calibration of satellite sensors and the validation of satellite-derived top-of-atmosphere (TOA) and surface reflectance products. A well-known practice for estimating surface reflectance is to conduct a field campaign with a spectrometer and a calibration panel, which is labor-intensive and expensive. To address this...

Understanding marsh elevation and accretion processes and vulnerability to rising sea levels across climatic and geomorphic gradients in California, USA Understanding marsh elevation and accretion processes and vulnerability to rising sea levels across climatic and geomorphic gradients in California, USA
Tidal marshes build elevations by below- and aboveground organic and mineral soil processes. Marsh elevation and accretion data can be used to determine if marshes are keeping pace with sea-level rise. Using a network of 54 deep rod surface elevation tables with paired feldspar marker horizon plots, we tracked elevation and accretion trends across 16 marshes in California, USA. All sites...

Characterization of acoustic detection efficiency using an unmanned surface vessel as a mobile receiver platform Characterization of acoustic detection efficiency using an unmanned surface vessel as a mobile receiver platform
Studies involving acoustic telemetry typically use stationary acoustic receivers arranged in an array or grid. Unmanned surface vehicle (USV)-based mobile receivers offer advantages over the latter approach: the USV can be programmed to autonomously carry a receiver to and from target locations, more readily adapting to a survey’s spatial scope and scale. This work examines the acoustic...

Response of Tiger Salamanders (Ambystoma t. tigrinum) to wetland restoration in a midwestern agricultural landscape, U.S.A. Response of Tiger Salamanders (Ambystoma t. tigrinum) to wetland restoration in a midwestern agricultural landscape, U.S.A.
Since the early 1990s, > 3,000 ha of wetlands (and adjacent prairie) have been restored on the row-crop agricultural landscape of Winnebago County, Iowa, U.S.A. From 2014–2016, we surveyed 45 wetlands among 19 easements for occupancy by Eastern Tiger Salamanders (Ambystoma tigrinum tigrinum) and used radio-telemetry to measure their patterns of movement and habitat use. Rates of...

Spatial asynchrony and cross-scale climate interactions in populations of a coldwater stream fish Spatial asynchrony and cross-scale climate interactions in populations of a coldwater stream fish
Climate change affects populations over broad geographic ranges due to spatially autocorrelated abiotic conditions known as the Moran effect. However, populations do not always respond to broad-scale environmental changes synchronously across a landscape. We combined multiple datasets for a retrospective analysis of time-series count data (5–28 annual samples per segment) at 144 stream...

Stress gradients structure spatial variability in coastal tidal marsh plant composition and diversity in a major Pacific coast estuary Stress gradients structure spatial variability in coastal tidal marsh plant composition and diversity in a major Pacific coast estuary
Understanding the drivers of variability in plant diversity from local to landscape spatial scales is a challenge in ecological systems. Environmental gradients exist at several spatial scales and can be nested hierarchically, influencing patterns of plant diversity in complex ways. As plant community dynamics influence ecosystem function, understanding the drivers of plant community...

Cisco population characteristics in Wisconsin lakes in relation to lake- and landscape-level factors Cisco population characteristics in Wisconsin lakes in relation to lake- and landscape-level factors
Objective Declines in Cisco Coregonus artedi populations in some inland lakes have prompted assessments of Cisco occurrence and extirpation risk in relation to various stressors to identify refuge lakes and factors that promote Cisco persistence. However, most previous assessments have focused on presence–absence of Cisco rather than examining how population characteristics, such as...

Observing coastal wetland transitions using national land cover products Observing coastal wetland transitions using national land cover products
Over the coming century, climate change and sea-level rise are predicted to cause widespread change to coastal wetlands. Estuarine vegetated wetlands can adapt to sea-level rise through both vertical development (i.e., biophysical feedbacks and sedimentation) and upslope/horizontal migration. Quantifying changes to estuarine vegetated wetlands over time can help to inform current and...

Grizzly bear responses to restrictions of recreation in Yellowstone National Park Grizzly bear responses to restrictions of recreation in Yellowstone National Park
Avoiding humans will be more difficult and energetically costly for animals as outdoor recreation increases and people venture farther into wildland areas that provide high-quality habitat for wildlife. Restricting human access can be an attractive management tool to mitigate effects of human recreation activities on wildlife; however, the efficacy of such measures is rarely assessed. In...

Evaluation of the US COVID-19 Scenario Modeling Hub for informing pandemic response under uncertainty Evaluation of the US COVID-19 Scenario Modeling Hub for informing pandemic response under uncertainty
Our ability to forecast epidemics far into the future is constrained by the many complexities of disease systems. Realistic longer-term projections may, however, be possible under well-defined scenarios that specify the future state of critical epidemic drivers. Since December 2020, the U.S. COVID-19 Scenario Modeling Hub (SMH) has convened multiple modeling teams to make months ahead...
