For a given k (k ≥ dL, where dL is the s-t link distance), one can compute a path in a simple polygon P whose length is guaranteed to be within a factor (1 + ε) of the length of a shortest k-link path, for any tolerance ε > 0. The algorithm runs in time O(n3k3 log...
1.1. The goal of niche modelling There is also a positive case for presence-only modelling. Central to the idea of the niche is the ecological concept of tolerance [10,20]. We start with the joint distribution of envi- ronments in nature p(z), z [ Rx (see tab...
whereas a high test results would predict more study success. Thus the negative relation between the test score and hGPA would mask the predictive power of the test. This also goes vice versa, if entrance test and
By demonstrating the trade-offs between performance and tolerance (Valladares et al., 2014; Riddell et al., 2019), Bergmann (1848) postulated that endotherms tend to be larger in colder climates compared with warmer habitats, while Allen's rule predicts that the size of appendages of animals ...
16]. Climate change causes dramatic shifts in geographical distributions of species. Species that are limited by their lower thermal tolerance threshold and are capable of at least partially tracking changes in climate experience significant range expansions [17]. Species from a variety of ecological ...

In theory, a principled choice should be guided by a formal definition of meaningful differences. In practice, it is convenient to normalize the tolerance by the standard deviation of the original time series. Since signal correlation properties contribute to entropy estimates, there is no ...
