'dissmapr' provides a reproducible, end-to-end workflow for computing and mapping compositional dissimilarity and biodiversity turnover across large spatial scales, including occurrence-data retrieval, environmental-data extraction, flexible grid generation, order-wise dissimilarity computation (zeta diversity and multi-site generalised dissimilarity modelling) and bioregional mapping.https://github.com/r-universe/b-cubed-eu/actions/runs/39225632565Tue, 21 Jul 2026 12:37:28 GMTdissmapr0.2.0successhttps://b-cubed-eu.r-universe.devhttps://github.com/b-cubed-eu/dissmaprdissmapr.Rmddissmapr.htmlGet started with dissmapr2026-06-26 14:03:482026-06-26 14:03:48macfadyen@sun.ac.za (Sandra MacFadyen)Utilities for assembling invader-resident interaction tensors, computing trait-based competition kernels from distance matrices, deriving environmental suitability kernels, calculating invasion fitness, and summarising trait dispersion metrics. Includes helpers to predict site-by-species responses for residents and simulated invaders, and to derive species invasiveness, site invasibility and trait-effect indicators. The package implements a network invasibility framework that decomposes invasion fitness into abiotic suitability, niche crowding and resident competition components, following the ecological-network theory of Hui and colleagues.https://github.com/r-universe/b-cubed-eu/actions/runs/38233377775Tue, 14 Jul 2026 19:22:46 GMTinvasimapr0.2.0successhttps://b-cubed-eu.r-universe.devhttps://github.com/b-cubed-eu/invasimaprinvasimapr.Rmdinvasimapr.htmlIntroduction to invasimapr2026-06-27 08:44:092026-07-07 12:33:18
