  • Temperature-mediated outbreak dynamics of the invasive bryozoan Membranipora membranacea in Nova Scotian kelp beds 

    Scheibling, Robert E., and Patrick Gagnon. 2009. "Temperature-mediated outbreak dynamics of the invasive bryozoan Membranipora membranacea in Nova Scotian kelp beds." Marine Ecology Progress Series 390: 1-13. doi:10.3354/meps08207
    We used underwater videography to examine seasonal and interannual patterns in the cover (on kelp) of the encrusting epiphytic bryozoan Membranipora membranacea, and associated changes in the structure and abundance of ...

  • Temporal and spatial variability in settlement and recruitment of echinoderms in kelp beds and barrens in Nova Scotia 

    Balch, Toby, and Robert E. Scheibling. 2000. "Temporal and spatial variability in settlement and recruitment of echinoderms in kelp beds and barrens in Nova Scotia." Marine Ecology Progress Series 205: 139-154. doi:10.3354/meps205139
    Settlement and recruitment of echinoderms were measured in 2 adjacent habitats: a kelp bed (Laminaria longicruris) and an echinoid (Strongylocentrotus droebachiensis)-dominated barren ground at each of 2 sites in the ...

  • Tidal and turbidity effects on the shallow-water fish assemblage of Kuwait Bay 

    Abou-Seedo, F., DA Clayton, and J. M. Wright. 1990. "Tidal and turbidity effects on the shallow-water fish assemblage of Kuwait Bay." Marine ecology progress series.Oldendorf 65(3): 213-223.
    Effects of location, diel period, tidal condition and water clarity on the size and distribution of the shallow water fish assemblage of the non-estuarine Kuwait Bay, were investigated using a beach seine and a small ...

  • Top down and bottom-up regulation of phytoplankton assemblages in tidepools 

    Metaxas, A., and RE Scheibling. 1996. "Top down and bottom-up regulation of phytoplankton assemblages in tidepools." Marine Ecology Progress Series 145(1-3): 161-177. doi:10.3354/meps145161
    We examined the relative importance of bottom-up (nutrient availability) and top-down (grazing) factors in regulating phytoplankton assemblages in tidepools on a rocky shore near Halifax, Nova Scotia, Canada. We manipulated ...

  • Two centuries of multiple human impacts and successive changes in a North Atlantic food web 

    Lotze, Heike K., and Inka Milewski. 2004. "Two centuries of multiple human impacts and successive changes in a North Atlantic food web." Ecological Applications 14(5): 1428-1447. Copyright by the Ecological Society of America
    European colonization of North America, severely altered terrestrial and aquatic ecosystems alike. Here, we integrate archaeological, historical, and recent data to derive the ecological history of the Quoddy Region, Bay ...

  • Unveiling Interactions among Mitochondria, Caspase-Like Proteases, and the Actin Cytoskeleton during Plant Programmed Cell Death (PCD) 

    Lord, Christina E. N., Adrian N. Dauphinee, Rebecca L. Watts, and Arunika H. L. A. N. Gunawardena. 2013. "Unveiling Interactions among Mitochondria, Caspase-Like Proteases, and the Actin Cytoskeleton during Plant Programmed Cell Death (PCD)." Plos One 8(3): 57110-e57110. doi:10.1371/journal.pone.0057110
    Aponogeton madagascariensis produces perforations over its leaf surface via programmed cell death (PCD). PCD begins between longitudinal and transverse veins at the center of spaces regarded as areoles, and continues ...

  • Variation in egg spawning among subpopulations of sea urchins Strongylocentrotus droebachiensis: a theoretical approach 

    Meidel, SK, and RE Scheibling. 2001. "Variation in egg spawning among subpopulations of sea urchins Strongylocentrotus droebachiensis: a theoretical approach." Marine Ecology Progress Series 213: 97-110. doi:10.3354/meps213097
    Variation in zygote production, by determining the initial size of the larvalpool, can aff ect the population dynamics of marine invertebrates with a planktonic larval stage. In this paper, we model temporal and spatial ...

  • Variation in milk production and lactation performance in grey seals and consequences for pup growth and weaning characteristics 

    Mellish, JAE, SJ Iverson, and WD Bowen. 1999. "Variation in milk production and lactation performance in grey seals and consequences for pup growth and weaning characteristics." Physiological and Biochemical Zoology 72(6): 677-690. Copyright © 1999 The University of Chicago Press.
    Phocid seals are one of the few groups of mammals capable of sustaining the energetic demands of lactation entirely through body nutrient stores while fasting. Lactation performance of the female in turn influences the ...

  • Variations in Sampling Procedure and Frequency Affect Estimates of Recruitment of Barnacles 

    MINCHINTON, TE, and RE SCHEIBLING. 1993. "Variations in Sampling Procedure and Frequency Affect Estimates of Recruitment of Barnacles." Marine Ecology Progress Series 99(1-2): 83-88. doi:10.3354/meps099083
    The influence of variations in sampling procedure and frequency on estimates of recruitment of the barnacle Semibalanus balanoides (L.) on an intertidal rocky shore at Sandy Cove, Nova Scotia, Canada was determined from ...

  • Weaning mass affects changes in body composition and food intake in harbour seal pups during the first month of independence 

    Muelbert, MMC, WD Bowen, and SJ Iverson. 2003. "Weaning mass affects changes in body composition and food intake in harbour seal pups during the first month of independence." Physiological and Biochemical Zoology 76(3): 418-427. Copyright © 2003 The University of Chicago Press.
    In phocid seals, the transition to nutritional independence is abrupt, with females abandoning their offspring after weaning and returning to sea. We hypothesized that body size at weaning may play an important role in ...

  • Why do fish stocks collapse? The example of cod in Atlantic Canada 

    Myers, RA, JA Hutchings, and NJ Barrowman. 1997. "Why do fish stocks collapse? The example of cod in Atlantic Canada." Ecological Applications 7(1): 91-106.
    In 1993, six Canadian populations of Atlantic cod (Gadus morhua) had collapsed to the point where a moratorium was declared on fishing. It has been argued that the collapses were caused by poor recruitment of cod to the ...
