    Since the type of forest influences vegetation patterns from the edge-to-interior forest, site-specific edge studies are needed but there have been few studies in open-canopied forests such as oak savannahs. Our objective ...

  • Harper, Karen A., 1969-; Butler, Wendy; O’Handley, Kaitlyn (Springer, 2023-11-07)
    Although forest edges surrounding lakes and wetlands are common in many heterogeneous landscapes, there are few studies on patterns of vegetation across these natural landscape boundaries. We investigated forest structure, ...

  • Harper, Karen A.; Yang, Jacqueline Renée; Dazé Querry, Natasha; Dyer, Julie; Alves, Rafael Souza Cruz; Ribeiro, Milton Cezar (Springer Netherland, 2024-04)
    Although Atlantic Forest is diverse and heavily fragmented, little is known about the impact of edges created from fragmentation on forest structure and plant diversity. Our investigation of vegetation at agricultural edges ...

    Non-native slugs, such as Arion, are becoming a concern for land managers in Nova Scotia, Canada, particularly in forested wetlands. They appear to have a highly diverse diet and may pose a particular risk to ...

    We use data on space distribution of the currently most complete sample of Cepheids with reliable distances (565 stars), located within ~5 kpc from the Sun, to study the spiral pattern of the Milky Way galaxy. We ...


  • Smith, Sigrid D. P.; McIntyre, Peter B.; Halpern, Benjamin S.; Cooke, Roger M.; Marino, Adrienne L.; Boyer, Gregory L.; Buchsbaum, Andy; Burton, G. A.; Campbell, Linda M., 1970-; iborowski, Jan J. H. (Ecological Society of America, 2015-04-01)
    Ecosystems often experience multiple environmental stressors simultaneously that can differ widely in their pathways and strengths of impact. Differences in the relative impact of environmental stressors can guide restoration ...

    We consider two extensions of free probability that have been studied in the research literature, and are based on the notions of c-freeness and respectively of infinitesimal freeness for noncommutative random ...

    We present a study of six far-infrared fine structure lines in the z = 4.225 lensed dusty star-forming galaxy SPT 0418−47 to probe the physical conditions of its interstellar medium (ISM). In particular, we report Atacama ...

  • Damjanov, Ivana; Zahan, H. Jabran; Gellar, Margaret J.; Fabricant, Daniel J.; Hwang, Ho Seong (Cornell University Library, arXiv.org, 2017-10)
    We describe the hCOSMOS redshift survey of the COSMOS field conducted with the Hectospec spectrograph on the MMT. In the central 1~deg$^2$, the hCOS20.6 subset of the survey is $>90\%$ complete to a limiting $r=20.6$. The ...

    Aims. We present and study spatially resolved imaging obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) of multiple 12CO(J = 6 − 5, 8−7, and 9−8) ...


  • Short, C. Ian; Bayer, Jason H.T.; Burns, Lindsey M. (The American Astronomical Society, 2018-02-20)
    We announce ChromaStarPy, an integrated general stellar atmospheric modeling and spectrum synthesis code written entirely in python V. 3. ChromaStarPy is a direct port of the ChromaStarServer (CSServ) Java modeling code ...

    Aperture synthesis arrays are commonly used in radio astronomy to take images of radio point sources, with the planned Square Kilometre Array (SKA) being the most common example. One approach to enhancing the quality of ...

  • Majaess, Daniel J.; Dékány, I.; Hadju, G.; Minniti, D.; Turner, David B.; Gieren, W. (Springer Netherlands, 2018-05-22)

    This study’s objective was to exploit infrared VVV (VISTA Variables in the Via Lactea) photometry for high latitude RRab stars to establish an accurate Galactic Centre distance. RRab candidates were discovered ...


  • Awalt, Jon Kyle; Scammels, Peter J.; Singer, Robert D. (American Chemical Society, 2018-08)
    A mechanochemical approach has been demonstrated for the selective cleavage of nitrogen–carbon bonds in the N-demethylation of various alkaloids relevant in the pharmaceutical industry. This methodology employs a range of ...
