Coelomic foreign bodies in wild-caught Python spp. in the Greater Everglades Ecosystem, Florida, USA Coelomic foreign bodies in wild-caught Python spp. in the Greater Everglades Ecosystem, Florida, USA
Burmese pythons (Python molurus bivittatus) and African rock pythons (Python sebae) have established invasive populations in southern Florida, severely disrupting local ecosystems. We analysed necropsy data from 2,179 pythons captured between 2006 and 2022, revealing nine cases of coelomic foreign bodies, primarily consisting of bird beaks, which presumably entered the coelom following...

Molecular evolution of TRPC4 regulatory sequences supports a role in mammalian thermoregulatory adaptation Molecular evolution of TRPC4 regulatory sequences supports a role in mammalian thermoregulatory adaptation
BackgroundProteins encoded by the canonical transient receptor potential (Trpc) gene family form transmembrane channels involved in diverse signal-transduction pathways. Trpc4 has been shown necessary for the induction of nonshivering thermogenesis (NST) in mice, a key component of which is thermogenic brown adipose tissue (BAT). In bats, Trpc4 exhibited diversifying selection within...

Adapting visitor use management under a changing climate across the U.S. National Park System Adapting visitor use management under a changing climate across the U.S. National Park System
Research shows that climate change is already affecting both resources and visitors in U.S. National Parks. We sought to better understand if and how park staff across the National Park Service are adapting to climatic changes that affect visitor use, as well as barriers and challenges to adaptation and information needs. We conducted semi-structured qualitative interviews with 63 staff...

Assessing the potential for evaluation of wildland fire models using remotely sensed data—Summary proceedings from a U.S. Geological Survey workshop in 2024 Assessing the potential for evaluation of wildland fire models using remotely sensed data—Summary proceedings from a U.S. Geological Survey workshop in 2024
On September 19, 2024, the U.S. Geological Survey (USGS) held a virtual workshop titled “Potential for Evaluation of Fire Models with Remote Sensing Data Workshop” to assess the feasibility of using remotely sensed datasets to evaluate next-generation wildland fire behavior models. Remote sensing and fire modelling experts gathered to: (1) assess the suitability of a variety of...

Using public participatory geographic information systems (PPGIS) to explore uses and values for Mojave Trails National Monument, California Using public participatory geographic information systems (PPGIS) to explore uses and values for Mojave Trails National Monument, California
Many people ascribe a variety of values to public lands and waters, but some values are more difficult to assess and quantify than others. Public participatory geographic information systems (PPGIS) are tools that have been used to help quantify and map the public’s diverse values for a landscape. This work describes the first known Office of Management and Budget–approved use of PPGIS...

Scoping decision-maker needs and science availability to support regional natural capital accounting in the U.S. Colorado River Basin Scoping decision-maker needs and science availability to support regional natural capital accounting in the U.S. Colorado River Basin
Natural capital accounting has the potential to yield important policy insights at multiple scales, but there remains a disconnect between regional-scale natural capital accounts and their use for informing policy. In this paper, we propose a roadmap that could lead to the creation of policy-relevant regional accounts, with steps split across an initial scoping phase and a subsequent...

Long-term geomorphic response of a southwestern USA river following establishment and removal of an invasive riparian tree Long-term geomorphic response of a southwestern USA river following establishment and removal of an invasive riparian tree
Invasion of non-native riparian vegetation along southwestern USA rivers is associated with channel narrowing and simplification, prompting numerous and varied removal efforts. Channel width and migration rate often, but not always, increase following treatment. The cause of this variability and the duration of response is poorly understood. Using flow records and aerial imagery we...

Cascading consequences and interventions for hazards after wildfire in Okanogan County, Washington Cascading consequences and interventions for hazards after wildfire in Okanogan County, Washington
This report details the application of the chains of consequences method within the postfire hazard context after the 2021 Cedar Creek and Muckamuck Fires around Okanogan County, Washington. The U.S. Geological Survey Social and Economic Analysis branch convened 20 stakeholders with content- and context-specific knowledge related to these fires and their postfire hazards in an April 2023...

U.S. Geological Survey Pollinator Science Strategy, 2025–35—A Review and Look Forward U.S. Geological Survey Pollinator Science Strategy, 2025–35—A Review and Look Forward
This “U.S. Geological Survey Pollinator Science Strategy, 2025–35—A Review and Look Forward” (“Pollinator Science Strategy”) describes the science vision of the U.S. Geological Survey (USGS) to support management, conservation, and policy decisions on animal pollinators and their habitats. As the science arm of the Department of the Interior, the USGS has a primary role in providing...

Novel adomaviruses associated with blotchy bass syndrome in black basses (Micropterus spp.) Novel adomaviruses associated with blotchy bass syndrome in black basses (Micropterus spp.)
Black bass (Micropterus spp.) are the most important warmwater game fishes in the United States. They have high socioeconomic and recreational value and support an important aquaculture industry. Since 2008, fisheries managers have been reporting the observation of hyperpigmented melanistic lesions (HPMLs) on smallmouth bass (M. dolomieu) in different ecoregions of the United States...

Legacies of a large flood and biological control on riparian vegetation successional trajectories along a dryland braided river Legacies of a large flood and biological control on riparian vegetation successional trajectories along a dryland braided river
The interplay of disturbance and stability drives vegetation dynamics. Disturbance reduces vegetation biomass, and stability fosters its development. In riparian systems, natural disturbance is largely manifested through flood-driven fluvial processes, but other forms of disturbance, such as herbivory or fire, may influence vegetation dynamics. We studied the successional trajectories of...
