    Effects of harvesting methods on sustainability of a bay scallop fishery: dredging uproots seagrass and displaces recruits

    Fishing is widely recognized to have profound effects on estuarine and marine ecosystems (Hammer and Jansson, 1993; Dayton et al., 1995). Intense commercial and recreational harvest of valuable species can result in population collapses of target and nontarget species (Botsford et al., 1997; Pauly et al., 1998; Collie et al. 2000; Jackson et al., 2001). Fishing gear, such as trawls and dredges, that are dragged over the seafloor inflict damage to the benthic habitat (Dayton et al., 1995; Engel and Kvitek, 1995; Jennings and Kaiser, 1998; Watling and Norse, 1998). As the growing human population, over-capitalization, and increasing government subsidies of fishing place increasing pressures on marine resources (Myers, 1997), a clear understanding of the mechanisms by which fishing affects coastal systems is required to craft sustainable fisheries management

By friendship we oft are deciev\u27d,And find the love we clung too, pastYet friendship will still be believdAnd love trusted on to the lastThe web in the leaves the spider weavesIs like the charm Hope hangs o\u27er men,Tho\u27 often she sees it broke by the breeze,She spins the bright tissue again,Aye, \u27tis all but &c

    [Verse 1]Tho\u27 \u27tis all but a drema at the best, And still when happiest soonest o\u27er; Yet ev\u27n in a dream to be blest Is so sweet, that I ask for no more; The bosom that opes with earliest hopes, The soonest finds those hopes untrue, As flowers that first in spring time burst The earliest wither too! Aye, \u27tis but a dream at the best, And still when happiest soonest o\u27er; Yet ev\u27n in a dream to be blest Is so sweet, that I ask for no more. [Verse 2]By friendship we oft are deciv\u27d, And find the love we clung too past: Yet frienship will still be believed And love trusted on to the last The web in the charm Hope hands o\u27er man, Tho\u27 often she sees it broke by the breeze, She spins the bright tissue again, Aye, \u27tis all but a dream

    The Delta Tree: An Object-Centered Approach to Image-Based Rendering

    Get PDF
    This paper introduces the delta tree, a data structure that represents an object using a set of reference images. It also describes an algorithm for generating arbitrary re-projections of an object by traversing its delta tree. Delta trees are an efficient representation in terms of both storage and rendering performance. Each node of a delta tree stores an image taken from a point on a sampling sphere that encloses the object. Each image is compressed by discarding pixels that can be reconstructed by warping its ancestor's images to the node's viewpoint. The partial image stored at each node is divided into blocks and represented in the frequency domain. The rendering process generates an image at an arbitrary viewpoint by traversing the delta tree from a root node to one or more of its leaves. A subdivision algorithm selects only the required blocks from the nodes along the path. For each block, only the frequency components necessary to reconstruct the final image at an appropriate sampling density are used. This frequency selection mechanism handles both antialiasing and level-of-detail within a single framework. A complex scene is initially rendered by compositing images generated by traversing the delta trees of its components. Once the reference views of a scene are rendered once in this manner, the entire scene can be reprojected to an arbitrary viewpoint by traversing its own delta tree. Our approach is limited to generating views of an object from outside the object's convex hull. In practice we work around this problem by subdividing objects to render views from within the convex hull
