    Can Orchards Help Connect Mediterranean Ecosystems? Animal Movement Data Alter Conservation Priorities

    Full text link
    As natural habitats become fragmented by human activities, animals must increasingly move through human-dominated systems, particularly agricultural landscapes. Mapping areas important for animal movement has therefore become a key part of conservation planning. Models of landscape connectivity are often parameterized using expert opinion and seldom distinguish between the risks and barriers presented by different crop types. Recent research, however, suggests different crop types, such as row crops and orchards, differ in the degree to which they facilitate or impede species movements. Like many mammalian carnivores, bobcats (Lynx rufus) are sensitive to fragmentation and loss of connectivity between habitat patches. We investigated how distinguishing between different agricultural land covers might change conclusions about the relative conservation importance of different land uses in a Mediterranean ecosystem. Bobcats moved relatively quickly in row crops but relatively slowly in orchards, at rates similar to those in natural habitats of woodlands and scrub. We found that parameterizing a connectivity model using empirical data on bobcat movements in agricultural lands and other land covers, instead of parameterizing the model using habitat suitability indices based on expert opinion, altered locations of predicted animal movement routes. These results emphasize that differentiating between types of agriculture can alter conservation planning outcomes

    The 16th Data Release of the Sloan Digital Sky Surveys: First Release from the APOGEE-2 Southern Survey and Full Release of eBOSS Spectra

    This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included. DR16 is also notable as the final data release for the main cosmological program of the Extended Baryon Oscillation Spectroscopic Survey (eBOSS), and all raw and reduced spectra from that project are released here. DR16 also includes all the data from the Time Domain Spectroscopic Survey and new data from the SPectroscopic IDentification of ERosita Survey programs, both of which were co-observed on eBOSS plates. DR16 has no new data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey (or the MaNGA Stellar Library "MaStar"). We also preview future SDSS-V operations (due to start in 2020), and summarize plans for the final SDSS-IV data release (DR17)

    Finishing the euchromatic sequence of the human genome

    The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

    Components of patient satisfaction with a dental restorative visit:results from the Dental Practice-Based Research Network

    No full text
    OBJECTIVES: Identify components of patient satisfaction with a dental restorative visit; and test the hypothesis that certain dentist, patient, and procedural factors are associated with patient satisfaction. METHODS: 197 practices in The Dental Practice-Based Research Network (DPBRN) recruited consecutive patients with defective restorations that were replaced or repaired in permanent teeth. At the end of the treatment visit, each subject was asked to complete a satisfaction survey and mail it directly to the DPBRN Regional Coordinators. RESULTS: Analysis of 5,879 satisfaction surveys revealed three satisfaction components which were interpersonal relationship-comfort attributes; material choice-value factors; and sensory-evaluative features. Satisfaction was highest among patients who received care in a private practice model; when the restoration was repaired rather than replaced; or when the restored tooth was not a molar. CONCLUSION: These data suggest that a patient’s judgments of dentist’s skills and quality of care are based on personal interactions with the dentist, the level of comfort, and post-treatment sensitivity. These conclusions have direct implications for patient management before, during and after the procedure. PRACTICE IMPLICATIONS: When taking a patient-centered approach, dentists should seek to understand how patients evaluate and rate the service provided, facilitating a focus on what each patient values most
