Examples

  • Major climate-related species distributions at the large scale include the limit of trees, which is associated with the isoline for mean July air temperatures of about 10 °C [3] (as discussed in [4]) and soil temperature of 7 °C [5], and the limit of woody plants such as dwarf shrubs that are one indicator of the boundary of the polar desert biome [6].

    Recent and projected changes in arctic species distributions and potential ranges

  • A contour line is an isoline that connects points on a map that have the same elevation.

    Topographic maps

  • A rigorous, independent study conducted in the U.S. under controlled conditions demonstrated that Bt maize yields anywhere from 12% less to the same as near-isoline (highly similar) conventional varieties (Ma & Subedi, 2005).

  • Page 456, Volume 4 be John's utility isolines, a utility isoline being the loci of all combinations of potatoes and eggs that have the same utility.

    Dictionary of the History of Ideas

  • The axiom says that along any isoline the marginal rate of substitution increases in favor of the commodity that is decreased.

    Dictionary of the History of Ideas

  • The pure geometry of Edgeworth's diagram led Fisher to note that in order to determine the optimal budget distribution we do not need to know how many utils each isoline represents: the knowledge of the isolines as such suffices.

    Dictionary of the History of Ideas

  • The budget distribution that maximizes John's total utility is the point M at which one isoline is tangent to this budget line.

    Dictionary of the History of Ideas

  • Naturally, utility increases as we move from an isoline to a “higher” one, from C2 to C3, for example.

    Dictionary of the History of Ideas

  • For Northern Europe, both effects roughly cancel (see the zero isoline separating the dark blue and light blue colors).

    GREENIE WATCH

  • In accordance to our laboratory studies, Bambawale et al. [35] observed no difference in cotton aphid abundance between Indian fields with Bt cotton (MECH 162) and its corresponding near isoline under integrated pest management.
