paleobuddy
paleobuddy can now simulate trait-dependent diversification, not just birth-death.
A side-by-side editorial comparison of n2khab and Rpath — release velocity, themes, recent moves, and the top alternatives to consider.
n2khab keeps retracting interpretations of habitat data it can't actually support
n2khab reads and prepares the standardised Flemish Natura 2000 habitat data sources — habitat maps, water surfaces, GRTS master grids — for reproducible analysis. Releases track the publication of new versioned data sources on Zenodo, but the more consequential ones change how the package interprets what it reads. The latest removes an argument outright after the reasoning behind it was found to be wrong.
Rpath 1.1.0 learns to read Ecopath's own files, easing migration off the desktop tool.
Rpath is NOAA's R implementation of the Ecopath with Ecosim mass-balance equations for marine food web models. The feed is an archive backfill and arrives out of version order, with several entries carrying only a journal abstract instead of release notes. The substantive recent work is 1.0.0, which paired real ecosim bug fixes with the documentation and packaging expected of a 1.0, and 1.1.0, which adds .eiixml import and new balance estimation.

Two forces shape the package. The first is external: each new habitatmap or watersurfaces vintage needs a supported reader, and the package has absorbed a steady stream of them. The second is a willingness to break its own API when the ecology does not support what the code claimed — the interpreted argument removed because type 3130 occurrences cannot be resolved to a single subtype, the rbbvos+ type dropped as too loosely defined, the collapse default changed to match how users actually need the output shaped. Return structures are also being normalised so element names no longer vary with data source version.
The package has said it expects future watersurfaces_hab versions to implement collapsing in the data source itself, so the corresponding argument is a candidate for removal once that lands — the same path the interpreted argument took.
Rpath is NOAA's R implementation of the Ecopath with Ecosim mass-balance equations for marine food web models. The feed is an archive backfill and arrives out of version order, with several entries carrying only a journal abstract instead of release notes. The substantive recent work is 1.0.0, which paired real ecosim bug fixes with the documentation and packaging expected of a 1.0, and 1.1.0, which adds .eiixml import and new balance estimation.
Development is moving from a faithful reimplementation of published equations toward a tool that can take over an existing modeling practice. Importing .eiixml files means models authored in the EwE desktop software no longer have to be rebuilt by hand, and the balance work reduces how many parameters a modeler must supply up front. The 1.0.0 release's contributor guidelines, issue templates and per-function examples point the same direction: preparing for users the maintainers do not personally know.
The next releases will likely widen the import path and tighten balance diagnostics, since 1.1.0 already spent effort on error messages for models missing parameters — the failure mode imported models will hit most.
