Figure 1 presents a four-species tree on which EDGE and HEDGE return different static species rankings under two simple transformations of fictional Red List categories (see Figure 1 legend).
a mode of property transformation, with such experiment actions as <incubate>, <heat>, <thaw>; a mode of transformation of spatial location, for example <move>; a mode of transformation of time, for example <wait>; a mode of category transformation, with such experiment actions as <break>, <pierce>, <divide>.
However, in this short note we highlight how the choice of transformation of Red List categories to different probabilities of extinction (see, e.g. Table 1) can affect the resulting species rankings for both the above metrics, sometimes dramatically.
We therefore used simulated trees and current IUCN data for mammals and birds to ask how strongly both EDGE and HEDGE rankings are affected by four transformations of the five most common Red List categories (LC, NT, VU, EN, and CR) to quantitative values for predicted prob(extinction) (see Table 1).
Read the list of categories.
For instance, Goertzel's transformation of (M,R) in category theory into a representation in division algebra [ 39] was dismissed by Louie for the reason that it altered the entailment structure [ 21].
Here, we proprose extending these studies to a categorical transformation (with m>2 categories) of the continuous variable by involving more than one parameter in the model; m−1 dummy variables are introduced in the model.
After World War I other categories of parties developed that were partly the result of divisions or transformations of older parties.
These transformations differ from the Galilean transformations of Newtonian mechanics.
The use of complex reference units, the assessment of numerous and diverse landscape functions, the transformation of natural scientific facts to categories of human society (by the evaluation procedure), and the elaboration of environmental goals (landscape visions) are essential characteristics of a genuine holistic approach in landscape ecology.
