Relationships between landscape constraints and a crayfish assemblage with consideration of competitor presence Relationships between landscape constraints and a crayfish assemblage with consideration of competitor presence
Aim Crayfish are globally diverse and one of the most important taxa in North American streams. Despite their importance, many species are of conservation concern and efforts to improve conditions are limited. Here, we address two major impediments to improving conditions: (a) our lack of knowledge of the interplay among natural landscape and human-induced changes; and (b) a very limited

Quantifying climate sensitivity and climate-driven change in North American amphibian communities Quantifying climate sensitivity and climate-driven change in North American amphibian communities
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >500,000 time-series observations for 81...

Resistance to deltamethrin in prairie dog (Cynomys ludovicianus) fleas in the field and in the laboratory Resistance to deltamethrin in prairie dog (Cynomys ludovicianus) fleas in the field and in the laboratory
Sylvatic plague poses a substantial risk to black-tailed prairie dogs (Cynomys ludovicianus) and their obligate predator, the black-footed ferret (Mustela nigripes). The effects of plague on prairie dogs and ferrets are mitigated using a deltamethrin pulicide dust that reduces the spread of plague by killing fleas, the vector for the plague bacterium. In portions of Conata Basin, Buffalo...

A statement of common ground regarding the role of wildfire in forested landscapes of the western United States A statement of common ground regarding the role of wildfire in forested landscapes of the western United States
For millennia, wildfires have markedly influenced forests and non-forested landscapes of the western United States (US), and they are increasingly seen as having substantial impacts on society and nature. There is growing concern over what kinds and amounts of fire will achieve desirable outcomes and limit harmful effects on people and nature. Moreover, the increasing complexity...

United States bat species of concern: A synthesis United States bat species of concern: A synthesis
In 1994 the federal government designated 24 species or subspecies of bats in the United States (U.S.) and its territories as Category 2 candidates for listing as Endangered or Threatened under the U.S. Endangered Species Act. Category 2 was eliminated in 1996, but taxa previously receiving this designation were informally considered “species of concern”. Various state and federal...

Does proximity to wetlands matter? A landscape-level analysis of the influence of local wetlands on the public’s concern for ecosystem services and conservation involvement Does proximity to wetlands matter? A landscape-level analysis of the influence of local wetlands on the public’s concern for ecosystem services and conservation involvement
The success of landscape-level conservation depends on public support and an understanding of public opinion. However, perceptions of wetlands’ importance may differ based on proximity to a wetland. This study used a mail-out survey across the entire U.S. (n=1,030) to investigate the public’s knowledge of local wetlands, visitation to wetlands, concern over losing ecosystem services...

Burn severity controls on postfire Araucaria‐Nothofagus regeneration in the Andean Cordillera Burn severity controls on postfire Araucaria‐Nothofagus regeneration in the Andean Cordillera
Aim The aim of the study was to investigate postfire regeneration patterns of Araucaria‐Nothofagus forests on the west slope of the Andes; to evaluate the relationship between remotely sensed burn severity and forest mortality; and to assess controls of burn severity on forest response at local spatio‐temporal scales. Location Araucanía region in the western Andean Range of south‐central...

Testing infrared camera surveys and distance analyses to estimate feral horse abundance in a known population Testing infrared camera surveys and distance analyses to estimate feral horse abundance in a known population
We tested the use of high‐resolution infrared (IR) camera technology and distance sampling analyses to estimate abundance of feral horses (Equus caballus) during 2015–2016 in the McCullough Peaks Herd Management Area, Wyoming, USA. Infrared technology is becoming more common in ungulate population monitoring. The quality of IR cameras now allows ungulate species to be differentiated...

Evaluating airsoft electric guns for control of invasive brown treesnakes Evaluating airsoft electric guns for control of invasive brown treesnakes
Firearms are often used in lethal control of invasive vertebrates, but safety and regulatory aspects limit the circumstances under which they can be used. During August 2016 at the Brown Treesnake Project laboratory on Guam, we evaluated hobby‐grade Airsoft Electric Guns (AEGs)—a lower powered, less‐hazardous, and less‐regulated alternative to firearms—for capture and control of small...

Exploring the amphibian exposome in an agricultural landscape using telemetry and passive sampling Exploring the amphibian exposome in an agricultural landscape using telemetry and passive sampling
This is the first field study of its kind to combine radio telemetry, passive samplers, and pesticide accumulation in tissues to characterize the amphibian exposome as it relates to pesticides. Understanding how habitat drives exposure in individuals (i.e., their exposome), and how that relates to individual health is critical to managing species in an agricultural landscape where...

Isolation, characterization and molecular identification of a novel aquareovirus that infects the endangered fountain darter, Etheostoma fonticola Isolation, characterization and molecular identification of a novel aquareovirus that infects the endangered fountain darter, Etheostoma fonticola
The fountain darter Etheostoma fonticola (FOD) is a federally endangered fish listed under the US Endangered Species Act. Here, we identified and characterized a novel aquareovirus isolated from wild fountain darters inhabiting the San Marcos River. This virus was propagated in Chinook salmon embryo (CHSE)-214, rainbow trout gonad-2 and fathead minnow cells at 15°C. The epithelioma...
