Risks of hydroclimatic regime shifts across the western United States Risks of hydroclimatic regime shifts across the western United States
Paleohydrologic reconstructions of water-year streamflow for 105 sites across the western United States (West) were used to compute the likelihood (risk) of regime (wet/dry state) shifts given the length of time in a specific regime and for a specified time in the future. The spatial variability of risks was examined and indicates that regime shift risks are variable across the West. The...

Seasonal patterns in hydrochemical mixing in three Great Lakes rivermouth ecosystems Seasonal patterns in hydrochemical mixing in three Great Lakes rivermouth ecosystems
Rivermouth ecosystems in the Laurentian Great Lakes represent complex hydrologic mixing zones where lake and river water combine to form biologically productive areas that are functionally similar to marine estuaries. As urban, industrial, shipping, and recreational centers, rivermouths are the focus of human interactions with the Great Lakes and, likewise, may represent critical habitat...

Use of high-throughput screening results to prioritize chemicals for potential adverse biological effects within a West Virginia Watershed Use of high-throughput screening results to prioritize chemicals for potential adverse biological effects within a West Virginia Watershed
Organic chemicals from industrial, agricultural, and residential activities can enter surface waters through regulated and unregulated discharges, combined sewer overflows, stormwater runoff, accidental spills, and leaking septic-conveyance systems on a daily basis. The impact of point and nonpoint contaminant sources can result in adverse biological effects for organisms living in or...

Soil warming effects on tropical forests with highly weathered soils Soil warming effects on tropical forests with highly weathered soils
The tropics are a region encircling the equator, delineated to the north by the Tropic of Cancer (23°26′14.0″N) and to the south by the Tropic of Capricorn (23°26′14.0″S). While we often think of the tropics as consistently warm and wet throughout the year, in reality, the tropics maintain a myriad of climates. Of the 116 Holdridge life zones (a global bioclimatic classification scheme)...

Evaluating and using existing models to map probable suitable habitat for rare plants to inform management of multiple-use public lands in the California desert Evaluating and using existing models to map probable suitable habitat for rare plants to inform management of multiple-use public lands in the California desert
Multiple-use public lands require balancing diverse resource uses and values across landscapes. In the California desert, there is strong interest in renewable energy development and important conservation concerns. The Bureau of Land Management recently completed a land-use plan for the area that provides protection for modeled suitable habitat for multiple rare plants. Three sets of...

Distinguishing disturbance from perturbations in fire-prone ecosystems Distinguishing disturbance from perturbations in fire-prone ecosystems
Fire is a necessary ecosystem process in many biomes and is best viewed as a natural disturbance that is beneficial to ecosystem functioning. However, increasingly we are seeing human interference in fire regimes that alter the historical range of variability for most fire parameters and result in vegetation shifts. Such perturbations can affect all fire regime parameters. Here we...

Phenological mismatch between season advancement and migration timing alters Arctic plant traits Phenological mismatch between season advancement and migration timing alters Arctic plant traits
1. Climate change is creating phenological mismatches between herbivores and their plant resources throughout the Arctic. While advancing growing seasons and changing arrival times of migratory herbivores has been shown to have consequences for herbivores and forage quality, developing mismatches are also likely to influence other traits of plants, such as above- and belowground biomass...

Long-term population dynamics of dreissenid mussels (Dreissena polymorpha and D. rostriformis): A cross-system analysis Long-term population dynamics of dreissenid mussels (Dreissena polymorpha and D. rostriformis): A cross-system analysis
Dreissenid mussels (including the zebra mussel Dreissena polymorpha and the quagga mussel D. rostriformis) are among the world's most notorious invasive species, with large and widespread ecological and economic effects. However, their long‐term population dynamics are poorly known, even though these dynamics are critical to determining impacts and effective management. We gathered and...

Understanding and mitigating bee drownings in open feeders Understanding and mitigating bee drownings in open feeders
Whereas open feeders are relatively inexpensive and are easily set up and maintained, they do present a drowning hazard to bees. We observed that bees feeding off the walls of the open container fell into the sugar water because of their incarnation, interactions with other bees and when shooed off the feeder walls while removing the feeder for cleaning. Twigs, angled laths and utility...

Precipitation and temperature drive continental scale patterns in stream invertebrate production Precipitation and temperature drive continental scale patterns in stream invertebrate production
Secondary production, the growth of new heterotrophic biomass, is a key process in aquatic and terrestrial ecosystems that has been carefully measured in many flowing water ecosystems. We combine structural equation modeling with the first worldwide dataset on annual secondary production of stream invertebrate communities to reveal core pathways linking air temperature and precipitation...

Aerosol transmission of gull-origin Iceland subtype H10N7 influenza A virus in ferrets Aerosol transmission of gull-origin Iceland subtype H10N7 influenza A virus in ferrets
Subtype H10 influenza A viruses (IAVs) have been recovered from domestic poultry and various aquatic bird species, and sporadic transmission of these IAVs from avian species to mammals (i.e., human, seal, and mink) are well documented. In 2015, we isolated four H10N7 viruses from gulls in Iceland. Genomic analyses showed four gene segments in the viruses were genetically associated with...
