VEGAN, a package of R functions for community ecology

TL;DR: VEGAN adds vegetation analysis functions to the general-purpose statistical program R, and implements several ordination methods, including Canonical Correspondence Analysis and Non-metric Multidimensional Scaling, vector fitting of environmental variables, randomization tests, and various other analyses of vegetation data.
Journal ArticleDOI

Size-specific sensitivity: applying a new structured population model

TL;DR: In this article, the authors introduced the integral projection model, which eliminates the need for division into discrete classes, without requiring any additional biological assumptions and provides estimates of the asymptotic growth rate, stable size distribution, reproductive values, and sensitivities of the growth rate to changes in vital rates.

Ripley's K Function

TL;DR: In this article, the properties of the Ripley's K function and two related functions are reviewed and interpreted using data on the locations of trees in a swamp hardwood forest, where points can be labeled by a small number of groups.
Journal ArticleDOI

Accounting for spatial pattern when modeling organism- environment interactions

TL;DR: This work considers several classes of statistical models appropriate for modeling environment-abundance relationships in the presence of spatial autocorrelation, and applies these to three case studies.
