Local demographic rates and CTMax values of four Eleutherodactylus frogs in Puerto Rico, 2017-2019

Jaime Collazo
We determined their critical thermal maximum (CTMax) of four species of Eleutherodactylus frogs (E. wightmanae, E. brittoni, E. antillensis, E. coqui) to understand their response to warming temperatures. Data consist of capture history, body condition, and temperature at which the frog exhibited spasms and erratic behavior, which may impair predator avoidance. Our results underscored the potential vulnerability of Eleutherodactylus species exhibiting lower CTMax to the forecasted warming of tropical zones (e.g., E. wightmanae, E. brittoni)....

Fire Risk Frequency Analysis- South Central Plains

Mark Shafer, Amy Hays, Brian Hays & John Weir
Fire is a natural and necessary component of the South Central Plains ecosystem. However, fire suppression and more frequent droughts in the region have resulted in a build-up of dry fuels loads such as dead wood, resulting in fires that burn hotter and impact the landscape more severely. Uncontrolled wildfires have cost the region several billion dollars in the past five years. Further, fire suppression has resulted in substantial losses in native plant biodiversity and...

Applications of Climate Downscaling in the Main Hawaiian Islands: Balancing Climate Modelers’ Products and Impact Modelers’ Expectations

David Helweg & Victoria Keener
High-resolution projections of future terrestrial climate conditions for the high Hawaiian islands (Hawaiʻi Island, Maui Nui, Oʻahu, and Kauaʻi) have been developed using statistical and dynamical downscaling methods. A “Workshop on Climate Downscaling and its Application in the High Hawaiian Islands” (https://pubs.er.usgs.gov/publication/ofr20161102) was held in 2015 to address questions from natural resource managers about how to integrate climate-related projections into their resource management decisions. Since the 2015 workshop, additional climate modeling has been done. New...

Conservation and Restoration Priorities for Wild Pollinator Habitat

Katie Warnell
Wild insect pollination has significant positive effects on pollinator-dependent crop production. While managed honeybees are often used to provide pollination to pollinator-dependent crops, visits by wild insect pollinators have been shown to be more effective in increasing fruit set than managed pollinators, and wild insect pollination increases fruit set even when managed pollinator visitation is high (Garibaldi et al. 2013). The total value of the pollination services provided by wild, native insects has been estimated...

Conservation Priorities for Open Space Access

Katie Warnell
Publicly accessible open spaces provide valuable opportunities for people to exercise, play, socialize, and build community. People are more likely to use public open spaces that are close (ideally within walking distance) to their homes. To assess the spatial distribution of access to open space for recreation in the southeastern United States, we constructed an index of open space access based on the size of the largest publicly accessible open space within 10 miles of...

Conservation and Restoration Priorities for Water Purification

Katherine Warnell
Clean water is important for a variety of uses, including drinking, recreation, and as habitat for aquatic species. Nonpoint-source pollution, such as nutrients, sediment, and pesticides from agricultural runoff, is a major cause of impaired water quality in the United States . Vegetation and soil in natural land cover help to remove pollutants from runoff water before it reaches streams and other waterways by slowing water flow and physically trapping sediment. To assess the spatial...

Pairwise comparisons of river herring run dynamics and environmental regimes among Massachusetts streams

Michelle Staudinger & Henry Legett
The timing of life-history events in many plants and animals depend on specific environmental conditions that fluctuate with seasonal conditions. Climate change is altering environmental regimes and disrupting natural cycles and patterns across communities. Anadromous fishes that migrate between marine and freshwater habitats to spawn are particularly sensitive to shifting environmental conditions, and thus are vulnerable to the effects of climate change. However, for many anadromous fish species the specific environmental mechanisms driving migration and...

We included a random...

County-level drought indices The Palmer Drought Severity Index(PDSI)and Palmer Hydrological Drought Index(PHDI)

& Robert V. Rohli
Drought is a natural hazard that inflicts costly damage to the environment and human communities. Although ample literature exists on the climatological aspects of drought, little is known on whether existing drought indices can predict the damages and how different human communities respond and adapt to the hazard. This project examines (1) whether existing drought indices can predict the occurrence of drought events and their actual damages; (2) how the adaptive capacity (i.e., resilience) varies...

Combined county-level drought incidence, damage, and census data

Volodymyr V. Mihunov, Nina S. N. Lam & Lei Zou
The threat of droughts and their associated impacts on the landscape and human communities have long been recognized in the United States, especially in high risk areas such as the southcentral region. This project examines whether existing drought indices can predict the occurrence of drought events and their actual damages, how the adaptive capacity (i.e., resilience) varies across space, and what public outreach and engagement effort would be most effective for mitigation of risk and...
