    Abstract: Managing wildlife populations in the face of global change requires regular data on the abundance and distribution of wild animals, but acquiring these over appropriate spatial scales in a sustainable way has proven challenging. Here we present the data from Snapshot USA 2020, a second annual national mammal survey of the USA. This project involved 152 scientists setting camera traps in a standardized protocol at 1485 locations across 103 arrays in 43 states for a total of 52,710 trap‐nights of survey effort. Most (58) of these arrays were also sampled during the same months (September and October) in 2019, providing a direct comparison of animal populations in 2 years that includes data from both during and before the COVID‐19 pandemic. All data were managed by the eMammal system, with all species identifications checked by at least two reviewers. In total, we recorded 117,415 detections of 78 species of wild mammals, 9236 detections of at least 43 species of birds, 15,851 detections of six domestic animals and 23,825 detections of humans or their vehicles. Spatial differences across arrays explained more variation in the relative abundance than temporal variation across years for all 38 species modeled, although there are examples of significant site‐level differences among years for many species. Temporal results show how species allocate their time and can be used to study species interactions, including between humans and wildlife. These data provide a snapshot of the mammal community of the USA for 2020 and will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, and the impacts of species interactions on daily activity patterns.

    SNAPSHOT USA 2019: a coordinated national camera trap survey of the United States

    Abstract: With the accelerating pace of global change, it is imperative that we obtain rapid inventories of the status and distribution of wildlife for ecological inferences and conservation planning. To address this challenge, we launched the SNAPSHOT USA project, a collaborative survey of terrestrial wildlife populations using camera traps across the United States. For our first annual survey, we compiled data across all 50 states during a 14‐week period (17 August–24 November of 2019). We sampled wildlife at 1,509 camera trap sites from 110 camera trap arrays covering 12 different ecoregions across four development zones. This effort resulted in 166,036 unique detections of 83 species of mammals and 17 species of birds. All images were processed through the Smithsonian’s eMammal camera trap data repository and included an expert review phase to ensure taxonomic accuracy of data, resulting in each picture being reviewed at least twice. The results represent a timely and standardized camera trap survey of the United States. All of the 2019 survey data are made available herein. We are currently repeating surveys in fall 2020, opening up the opportunity to other institutions and cooperators to expand coverage of all the urban–wild gradients and ecophysiographic regions of the country. Future data will be available as the database is updated at eMammal.si.edu/snapshot‐usa, as will future data paper submissions. These data will be useful for local and macroecological research including the examination of community assembly, effects of environmental and anthropogenic landscape variables, effects of fragmentation and extinction debt dynamics, as well as species‐specific population dynamics and conservation action plans.

    Murine FATP alleviates growth and biochemical deficiencies of yeast fat1 Δ strains

    Abstract: Saccharomyces cerevisiae is an ideal model eukaryote for studying fatty‐acid transport. Yeast are auxotrophic for unsaturated fatty acids when grown under hypoxic conditions or when the fatty‐acid synthase inhibitor cerulenin is included in the growth media. The FAT1 gene encodes a protein, Fat1p, which is required for maximal levels of fatty‐acid import and has an acyl CoA synthetase activity specific for very‐long‐chain fatty acids suggesting this protein plays a pivotal role in fatty‐acid trafficking. In the present work, we present evidence that Fat1p and the murine fatty‐acid transport protein (FATP) are functional homologues. FAT1 is essential for growth under hypoxic conditions and when cerulenin was included in the culture media in the presence or absence of unsaturated fatty acids. FAT1 disruptants ( fat1 Δ) fail to accumulate the fluorescent long‐chain fatty acid fatty‐acid analogue 4,4‐difluoro‐5‐methyl‐4‐bora‐3a,4a‐diaza‐s‐indacene‐3‐dodecanoic acid (C 1 ‐BODIPY‐C 12 ), have a greatly diminished capacity to transport exogenous long‐chain fatty acids, and have very long‐chain acyl CoA synthetase activities that were 40% wild‐type. The depression in very long‐chain acyl CoA synthetase activities were not apparent in cells grown in the presence of oleate. Additionally, β‐oxidation of exogenous long‐chain fatty acids is depressed to 30% wild‐type levels. The reduction of β‐oxidation was correlated with a depression of intracellular oleoyl CoA levels in the fat1 Δ strain following incubation of the cells with exogenous oleate. Expression of either Fat1p or murine FATP from a plasmid in a fat1 Δ strain restored these phenotypic and biochemical deficiencies. Fat1p and FATP restored growth of fat1 Δ cells in the presence of cerulenin and under hypoxic conditions. Furthermore, fatty‐acid transport was restored and was found to be chain length specific: octanoate, a medium‐chain fatty acid was transported in a Fat1p‐ and FATP‐independent manner while the long‐chain fatty acids myristate, palmitate, and oleate required either Fat1p or FATP for maximal levels of transport. Lignoceryl CoA synthetase activities were restored to wild‐type levels in fat1 Δ strains expressing either Fat1p or FATP. Fat1p or FATP also restored wild‐type levels of β‐oxidation of exogenous long‐chain fatty acids. These data show that Fat1p and FATP are functionally equivalent when expressed in yeast and play a central role in fatty‐acid trafficking.
