The perfect mixing paradox and the logistic equation: Verhulst vs. Lotka

open access: yesEcosphere, 2016
A theoretical analysis of density‐dependent population dynamics in two patches sheds novel light on our understanding of basic ecological parameters. Firstly, as already highlighted in the literature, the use of the traditional r‐K parameterization for ...

Cubic q-Bézier Triangular Patch for Scattered Data Interpolation and Its Algorithm

open access: yesAlgorithms
This paper presents an approach to scattered data interpolation using q-Bézier triangular patches via an efficient algorithm. While existing studies have formed q-Bézier triangular patches through convex combination, their application to scattered data ...

The disproportionately high value of small patches for biodiversity conservation

open access: yesConservation Letters, 2022
Small habitat patches have been historically neglected in conservation, primarily because extinction risk is higher in small patches. Nevertheless, sets of small patches usually harbor more species than one or a few larger patches of equal total area ...
