The goal of the U.S. Climate Resilience Toolkit’s (CRT) Climate Explorer (CE) is to provide information at appropriate spatial and temporal scales to help practitioners gain insights into the risks posed by climate change. Ultimately, these insights can lead to groups of local stakeholders taking action to build their resilience...
Implementation of a surface water extent model in Cambodia using cloud-based remote sensing
Christopher E. Soulard, Jessica J. Walker, Roy E. Petrakis
2020, Remote Sensing (12)
Mapping surface water over time provides the spatially explicit information essential for hydroclimatic research focused on droughts and flooding. Hazard risk assessments and water management planning also rely on accurate, long-term measurements describing hydrologic fluctuations. Stream gages are a common measurement tool used to better understand flow and inundation dynamics,...
A critical review on the potential impacts of neonicotinoid insecticide use: Current knowledge of environmental fate, toxicity, and implications for human health
Hans-Joachim Lehmler, Dana W. Kolpin, Michelle L. Hladik, John D. Vargo, Keith E. Schilling, Gregory H. LeFevre, Tonya L. Peeples, Matthew C. Poch, Lauren E. LaDuca, David M. Cwiertny, R. William Field

Neonicotinoid insecticides are widely used in both urban and agricultural settings around the world. Historically, neonicotinoid insecticides have been viewed as ideal replacements for more toxic compounds, like organophosphates, due in part to their perceived limited potential to affect the environment and human health. This critical review investigates the environmental...

Lakewide acoustic (AT) and bottom trawl (BT) surveys are conducted annually to generate indices of pelagic and benthic prey fish densities in Lake Michigan. The BT survey has been conducted each fall since 1973 using 12-m trawls at depths ranging from 9 to 110 m and include 70 fixed locations...
A within-season approach for detecting early crop stage of corn and soybean using high temporal and spatial resolution imagery
Feng Gao, Martha Anderson, Craig S. T. Daughtry, Arnon Karnieli, W. Dean Hively, William P. Kustas
2020, Remote Sensing of Environment (242)
Crop emergence is a critical stage for crop development and crop growth modeling. Mapping crop emergence using remote sensing data is challenging. Previous remote sensing phenology algorithms showed that crop stages could be detected around the V3-V4 (3 to 4 established leaves) vegetative stage. Traditional approaches have a strong assumption...
Detecting commonality in multidimensional fish movement histories using sequence analysis
Michael R. Lowe, Christopher M. Holbrook, Darryl W. Hondorp
2020, Animal Biotelemetry (8)
BackgroundAcoustic telemetry, for tracking fish movement histories, is multidimensional capturing both spatial and temporal domains. Oftentimes, analyses of such data are limited to a single domain, one domain nested within the other, or ad hoc approaches that simultaneously consider both domains. Sequence analysis, on the other hand, offers...

Relocated aftershocks and background seismicity in eastern Indonesia shed light on the 2018 Lombok and Palu earthquake sequences
Pepen Supendi, Andri Dian Nugraha, Sri Widiyantoro, Jeremy D. Pesicek, C.H. Thurber, C.I. Abdullah, D. Daryono, S.H. Wiyono, H.A. Shiddiqi, S. Rosalia
2020, Geophysical Journal International (221) 1845-1855
High seismicity rates in eastern Indonesia occur due to the complex interaction of several tectonic plates which resulted in two deadly, destructive earthquake sequences that occurred in Lombok Island and the city of Palu, Sulawesi in 2018. The first sequence began in July with an Mw 6.4 event near Lombok, culminating in...
Consequences of ignoring group association in spatial capture-recapture analysis
Richard Bischof, Pierre Dupont, Cyril Milleret, Joseph Chipperfield, J. Andrew Royle
2020, Wildlife Biology (2020)
Many models in population ecology, including spatial capture–recapture (SCR) models, assume that individuals are distributed and detected independently of one another. In reality, this is rarely the case – both antagonistic and gregarious relationships lead to non-independent spatial configurations, with territorial exclusion at one end of the spectrum and group-living...

Cool and warm season precipitation totals have been reconstructed on a gridded basis for North America using 439 tree-ring chronologies correlated with December-April totals and 547 different chronologies correlated with May-July totals. These discrete seasonal predictor chronologies are not significantly correlated with the alternate season and the reconstructions calibrate...
Map depicting susceptibility to landslides triggered by intense rainfall, Puerto Rico
K. Stephen Hughes, William H. Schulz
2020, Open-File Report 2020-1022
Landslides in Puerto Rico range from nuisances to deadly events. Centuries of agricultural and urban modification of the landscape have perturbed many already unstable hillsides on the tropical island. One of the main triggers of mass wasting on the island is the high-intensity rainfall that is associated with tropical atmospheric...

Investigation of bed and den site selection by American black bears (Ursus americanus) in a landscape impacted by forest restoration treatments and wildfires
Susan M. Bard, James W. Cain III
2020, Forest Ecology and Management (460) 1-11
The combined effects of long-term fire suppression, logging, and overgrazing have negatively impacted many southwestern U.S. forests, resulting in decreased habitat quality for wildlife, and more frequent and severe wildfires. In response, land management agencies are implementing large-scale forest restoration treatments, but data on how wildlife respond to restoration...

Rory O’Connor, Matthew J. Germino, David M Barnard, Caitlin M. Andrews, John B. Bradford, David S. Pilliod, Robert S. Arkle, Robert K Shriver
2020, Environmental Research Letters (15)
Ecological droughts are deficits in soil–water availability that induce threshold-like ecosystem responses, such as causing altered or degraded plant-community conditions, which can be exceedingly difficult to reverse. However, 'ecological drought' can be difficult to define, let alone to quantify, especially at spatial and temporal scales relevant to land managers. This...

The majority of variation in six traits critical to the growth, survival and reproduction of global plant species is thought to be organised along just two dimensions, corresponding to strategies of plant size and resource acquisition. However, it is unknown whether global plant trait relationships extend to climatic extremes, and...
