Point Count Survey Data of Avian Community Occupancy and DNA metabarcoding of pig diet at Felsenthal National Wildlife Refuge Complex, 2023-2024 Point Count Survey Data of Avian Community Occupancy and DNA metabarcoding of pig diet at Felsenthal National Wildlife Refuge Complex, 2023-2024
This release contains data from two parts of a project investigating the impacts of Wild Hogs on native wildlife. The first is a summary of Point Count Survey Data conducted during the summers of 2023 and 2024 to evaluate the impacts of hog presence and damage on the distribution of the avian community. The second part of the data release is DNA metabarcoding diet data from wild hogs...
Database of Biodiversity, Habitat, and Aquatic Resource Quantification Tools Used for Market-based Conservation in the United States (ver. 2.0, June 2022) Database of Biodiversity, Habitat, and Aquatic Resource Quantification Tools Used for Market-based Conservation in the United States (ver. 2.0, June 2022)
This comprehensive database describes the core attributes of quantification tools developed for market-based conservation in the United States. It encompasses tools designed for compensatory mitigation, non-compensatory mitigation, and voluntary conservation/restoration programs. The dataset consists of 107 tools. Each tool's features are described using 33 attributes related to general...
Nesting and post-fledging predation risk influence diel patterns of songbird fledging Nesting and post-fledging predation risk influence diel patterns of songbird fledging
Among stages of avian ontogeny, the act of nest departure or fledging is an abrupt transition into a new environment and a major leap toward independence for offspring. In altricial birds, the timing of fledging is notable in that many species tend to fledge early in the morning. Past studies have proposed nest predation as a key factor driving birds to fledge earlier in the morning (the...

The value of scientific information — An overview The value of scientific information — An overview
IntroductionThe U.S. Geological Survey (USGS) provides reliable science, data, information, and models (hereafter collectively referred to as “information”) to describe and understand the Earth. This information is used to minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect quality of life. USGS...

The economic costs of chronic wasting disease in the United States The economic costs of chronic wasting disease in the United States
Cervids are economically important to a wide range of stakeholders and rights holders in the United States. The continued expansion of chronic wasting disease (CWD), a fatal neurodegenerative disease affecting wild and farmed cervids, poses a direct and indirect threat to state and federal government agency operations and cervid related economic activity. However, the scale of this...

Database of biodiversity, habitat, and aquatic-resource quantification tools used in market-based conservation — 2022 update Database of biodiversity, habitat, and aquatic-resource quantification tools used in market-based conservation — 2022 update
Market-based conservation makes use of economic incentives to promote actions that avoid, minimize, or compensate for detrimental effects on natural resources and the environment. Examples of market-based conservation mechanisms include aquatic-resource (such as, streams, wetlands, and estuaries) compensatory mitigation, conservation banking, habitat exchanges, and payments for ecosystem...

Value of information and decision pathways: Concepts and case studies Value of information and decision pathways: Concepts and case studies
Information used in decision making arises from the structuring of observations and data. The collection, dissemination, and use of information has monetary and non-monetary costs (e.g., competition for attention) and necessitates trade-offs. Understanding the benefits of having information (i.e., the value of information, VOI), including resulting societal outcomes, is useful to...

Value of information: Exploring behavioral and social factors Value of information: Exploring behavioral and social factors
There is growing interest within and beyond the economics community in assessing the value of information (VOI) used in decision making. VOI assessments often do not consider the complex behavioral and social factors that affect the perception, valuation, and use of information by individuals and groups. Additionally, VOI assessments frequently do not examine the full suite of...

Economic valuation of health benefits from using geologic data to communicate radon risk potential Economic valuation of health benefits from using geologic data to communicate radon risk potential
Background: Radon exposure is the second leading cause of lung cancer worldwide and represents a major health concern within and outside the United States. Mitigating exposure to radon is especially critical in places with high rates of tobacco smoking (e.g., Kentucky, USA), as radon-induced lung cancer is markedly greater among people exposed to tobacco smoke. Despite homes being a...

Trends in biodiversity and habitat quantification tools used for market‐based conservation in the United States Trends in biodiversity and habitat quantification tools used for market‐based conservation in the United States
Market-based conservation mechanisms are designed to facilitate conservation and mitigation actions for habitat and biodiversity. Their potential is partly hindered, however, by issues surrounding the quantification tools used to assess habitat quality and functionality. Specifically, a lack of transparency and standardization in tool development and gaps in tool availability are cited...

A database of biodiversity and habitat quantification tools used in market-based conservation A database of biodiversity and habitat quantification tools used in market-based conservation
Market-based conservation uses economic incentives to leverage market forces in ways that encourage and improve efficiency in the restoration, enhancement, and preservation of species and habitats. Biodiversity and habitat quantification tools are vital to the operation of this conservation strategy, as they are used to measure the quality and functionality of areas of land that have...
