There is growing interest in using deep learning models to automate wildlife detection aerial imaging surveys increase efficiency, but human-generated annotations remain necessary for model training. However, even skilled observers may diverge interpreting imagery of complex environments, which result downstream instability models. In this study, we present a framework assessing annotation reliability by calculating agreement metrics individual against an aggregated set generated clustering...

Fifty-five infants and children with complications of gastroesophageal reflux required operative management for control symptoms. All patients, except those severe esophageal stricture, received a six-week trial 60-degree constant elevation before an operation was considered necessary. The performed to (1) persistent vomiting, (2) vomiting growth retardation, (3) esophagitis, (4) esophagitis (5) recurrent aspiration pneumonia. Preoperative postoperative evaluation involved both X-ray...
Abstract The decline of neotropical migratory birds in North America is closely tied to habitat loss, including the degradation bottomland hardwood and riparian forests, which provide essential habitats for numerous species. To address this, U.S. Fish Wildlife Service conducts bird surveys monitor restoration efforts evaluate conservation outcomes. This study assessed avian from three National Refuges Texas Oklahoma, using simulations, field data, literature current sampling protocols. Our...
Abstract Ecohydrology combines empiricism, data analytics, and the integration of models to characterize linkages between ecological hydrological processes. A challenge for practitioners is determining which best generalizes heterogeneity in behaviour, including water fluxes across spatial temporal scales, integrating environmental socio‐economic activities determine watershed management practices requirements. We conducted a literature review synthesis hydrologic, hydraulic, quality,...
Abstract Climate change shifts ecosystems, altering their compositions and instigating transitions, making climate the predominant driver of ecosystem instability. Land management agencies experience these climatic effects on ecosystems they administer yet lack applied information to inform mitigation. We address this gap, explaining by building relationships between historical locations 22 (c. 2000) abiotic data (1970–2000; bioclimate, terrain) within southwestern United States using...
Technological and methodological advances in remote sensing machine learning have created new opportunities for advancing wildlife surveys. We assembled a Community of Practice (CoP) to capitalize on these developments explore improvements the efficiency effectiveness aerial monitoring from management perspective. The core objective CoP is organize development testing methods improve population surveys that support decisions. Beginning 2020, collaboratively identified natural resource...
Abstract Establishing protected areas has long been an effective conservation strategy and is often based on readily surveyed species. The potential of any freshwater taxa to be a surrogate for other aquatic groups not explored fully. We compiled occurrence data 72 species fishes, amphibians, mussels, reptiles the Great Plains, Wyoming (U.S.A.). used hierarchical Bayesian multispecies mixture models MaxEnt describe species’ distributions program Zonation identify priority each group....
Fish in the South American genus Arapaima Müller, 1843 (hereafter referred to as arapaimas) have attracted interest for commercial aquaculture development thanks their rapid growth rate and high market value. However, management agencies United States expressed concerns about importing culturing arapaimas due records of non-native establishment certain other countries where were released or escaped from captivity. We used Freshwater Injurious Species Risk Assessment Model (FISRAM) estimate...
Abstract Previously published studies of the age estimation channel catfish Ictalurus punctatus based on otoliths have reported using sagittae, whereas it is likely they were actually lapilli. This confusion may resulted because in catfishes (ostariophyseans) lapilli are largest three otoliths, nonostariophysean fish sagittae largest. Based (1) scanning electron microscope microphotographs (2) X‐ray computed tomography scans a head, (3) descriptions techniques used to removed from...

Abstract With most of the world’s Caprinae taxa threatened with extinction, IUCN appeals to development simple and affordable sampling methods that will produce credible abundance distribution data for helping conserve these species inhabiting remote areas. Traditional approaches, like aerial or mark-capture-recapture, can generate bias by failing meet assumptions, incurring too much cost logistical burden projects address them. Therefore, we met IUCN’s challenge testing a technique...
Abstract Management of Blue Catfish Ictalurus furcatus and Channel I. punctatus for trophy production has recently become more common. Typically, management is attempted with length‐based regulations that allow the moderate harvest small fish but restrict larger fish. However, specific used vary considerably across populations, no modeling efforts have evaluated their effectiveness. We simulation to compare total yield, biomass ( B ), sustainability (spawning potential ratio [SPR] > 0.30)...
Data describing population abundance, survival, and recruitment informs species conservation status actions. Acquiring these data remains challenging for rare endangered species, especially freshwater fish, with ~ 37% threatened or extinct. The absence of risks inaction, ineptness ignorance that can contaminate decisions to the detriment. solution is obvious: ensure credible underpin conservation. We focus on Yaqui catfish (Ictalurus pricei), an endangered, endemic Sonoran desert (Arizona,...
