Creating an updated vegetation map for Big Oaks National Wildlife Refuge: Final report Creating an updated vegetation map for Big Oaks National Wildlife Refuge: Final report
Although Big Oaks NWR encompasses much diversity in wildlife species, an up-to-date, detailed, and comprehensive map showing vegetation types was lacking. The creation of an updated vegetation map for Big Oaks NWR was approved in early 2019. Digital aerial imagery was collected on November 1, 2019 at a resolution of 0.15 meter per pixel using four spectral bands: red, green, blue, and...

Ectoparasitism and energy infrastructure limit survival of preadult Golden Eagles in the Southern Great Plains Ectoparasitism and energy infrastructure limit survival of preadult Golden Eagles in the Southern Great Plains
Much of the US Southern Great Plains (SGP) continues to undergo intensive energy development that could affect the region's Golden Eagles (Aquila chrysaetos), yet the species' population status there is unknown. During 2011–2020, we used satellite telemetry to assess annual survival rates and causes of mortality among 40 preadult (

Declining American Goshawk (Accipiter atricapillus) nest site habitat suitability in a timber production landscape: Effects of abiotic, biotic, and forest management factors Declining American Goshawk (Accipiter atricapillus) nest site habitat suitability in a timber production landscape: Effects of abiotic, biotic, and forest management factors
Conservation of the American Goshawk (Accipiter atricapillus; hereafter goshawk) has been contentious in relation to forest management. Higher quality goshawk nesting habitat is generally considered to consist of contiguous tracts of mature forest, due to goshawks' large home ranges, territoriality, and food requirements. The large trees of mature forest have the greatest economic value...

Movement beyond the mean: decoupling sources of individual variation in brook trout movement across seasons Movement beyond the mean: decoupling sources of individual variation in brook trout movement across seasons
Movement is an important eco-evolutionary process that can shape population and ecosystem structure and function. Accordingly, a firm understanding of species movement ecology is often foundational to effective management and conservation. However, despite movement being an inherently individual-level behavior, there remains a tendency to describe dispersal and migration patterns using...

Winter distribution of golden eagles in the Eastern USA Winter distribution of golden eagles in the Eastern USA
Golden Eagles (Aquila chrysaetos) have a Holarctic distribution, but some details of that overall distribution are poorly understood, including parts of the range in eastern North America. Recent studies in the region suggest that Golden Eagles may be more widely distributed than previously recognized. For species specific conservation efforts to be effective, an understanding of the...

A workshop to advance invasive species early detection capacity of The Rapid Environmental DNA Assessment and Deployment Initiative & Network (READI-Net) A workshop to advance invasive species early detection capacity of The Rapid Environmental DNA Assessment and Deployment Initiative & Network (READI-Net)
Early detection and rapid response (EDRR) can minimize the impacts of invasive species, which cost billions of dollars globally. To bolster EDRR across the United States, the U.S. Department of the Interior is working with the U.S. Geological Survey and other partners to advance a National EDRR Framework that strengthens tools, actions, and processes to find and eradicate invasive...

A pragmatic approach for integrating molecular tools into biodiversity conservation A pragmatic approach for integrating molecular tools into biodiversity conservation
Molecular tools are increasingly applied for assessing and monitoring biodiversity and informing conservation action. While recent developments in genetic and genomic methods provide greater sensitivity in analysis and the capacity to address new questions, they are not equally available to all practitioners: There is considerable bias across institutions and countries in access to...

Matching existing and future native plant materials to disturbance-driven restoration needs Matching existing and future native plant materials to disturbance-driven restoration needs
Assessing the appropriateness of existing native plant materials can both determine which seed source to utilize for restoration projects, and identify locations for which new seed sources need to be developed. Here, we demonstrate an approach to meet these needs. This method identifies areas of high restoration need based on disturbance patterns, assesses the regional suitability of...

How long have we been mistaken? Multi-tools shedding light into the systematics of the widespread deep-water genus Madrepora Linnaeus, 1758 (Scleractinia) How long have we been mistaken? Multi-tools shedding light into the systematics of the widespread deep-water genus Madrepora Linnaeus, 1758 (Scleractinia)
Deep-water coral reefs are found worldwide and harbor biodiversity levels that are comparable to their shallow-water counterparts. However, the genetic diversity and population structure of deep-water species remain poorly explored, and historical taxonomical issues still need to be resolved. Here we used microsatellite markers as well as ultraconserved elements (UCE) and exons to shed...

Usurpation and brooding of Least Tern (Sternula antillarum) chicks by Common Terns (Sterna hirundo) Usurpation and brooding of Least Tern (Sternula antillarum) chicks by Common Terns (Sterna hirundo)
While nest usurpation and subsequent incubation of eggs and even brooding of chicks from other species has been reported for Common Terns (Sterna hirundo), such behavior is considered rare. We report an observation of a Common Tern pair usurping the Least Tern (Sternula antillarum) nest and brooding the Least Tern chicks. While the Least Tern pair attempted to provide care for the chicks...

Automated construction of Streamflow-Routing networks for MODFLOW—Application in the Mississippi Embayment region Automated construction of Streamflow-Routing networks for MODFLOW—Application in the Mississippi Embayment region
In humid regions with dense stream networks, surface water exerts a fundamental control on the water levels and flow directions of shallow groundwater. Understanding interactions between groundwater and surface water is critical for managing groundwater resources and groundwater-dependent ecosystems. Representing streams in groundwater models has historically been arduous and error prone...
