📊 Tree Statistics
Parsimony fit indices for your current tree and matrix.
🎰 Bootstrap Support
Assess clade support by resampling characters with replacement.
💪 Bremer Support
Calculate decay indices for each clade. Higher values = stronger support.
🔀 Branch Swapping TNT
Advanced tree rearrangement algorithms: TBR, SPR, and NNI.
🔀 Parsimony Ratchet
Heuristic search for most parsimonious trees. Runs in Web Worker — handles 10,000+ taxa without freezing.
🗺️ Ancestral Range Estimation (DEC)
Dispersal-Extinction-Cladogenesis (DEC) model. Reconstructs biogeographic history across your phylogeny.
🔬 GBIF Live Search
Query the Global Biodiversity Information Facility for real-time species occurrence data.
Or import occurrences for all taxa in your tree:
⚡ Analytical Engines
Cloud-scale heuristic searches and ancestral range estimation
Synapomorphy List
List character changes (synapomorphies) supporting each clade.
Character Weighting
Apply implied weights using Goloboff's k-value for downweighting homoplasious characters.
Homoplasy Detection
Identify convergences and reversals in your character data.
R Parsimony Search
Run Fitch parsimony + NNI tree search directly in your browser via ape. No server
required.
R Ancestral States
Reconstruct ancestral character states via Fitch parsimony downpass using ape.
R Model Test
Compare distance models (JC69, K80, T92, TN93) using ape::dist.dna. For
molecular (DNA) data only.
Constraint Tree Analysis
Search for optimal trees while enforcing monophyly constraints. Define backbone or partial constraints.
Click taxa to add to constraint group:
Successive Approximations
Iterative character reweighting based on CI/RI. Downweights homoplasious characters until tree stability.
Parsimony Jackknifing
Fast resampling method that deletes a fraction of characters per replicate. Faster than bootstrap for large datasets.
Symmetric Resampling
Goloboff's symmetric resampling avoids artifacts of standard bootstrap/jackknife. Better for parsimony.
Partitioned Bremer Support
Calculate Bremer support for character partitions. Identifies which data partitions support each clade.
Molecular Clock Calibration
Set calibration points to convert branch lengths to absolute time. Supports fossil-based and secondary calibrations.
Divergence Time Display
Visualize estimated divergence times on tree. Toggle time scale, geological epochs, and confidence intervals.
Trait Evolution Animation
Animate character state changes across the phylogeny through time. Visualize evolutionary transitions.
Biogeographic Regions
Define custom biogeographic areas for ancestral range estimation. Assign taxa to regions with area codes.
Event-Based Biogeography
Infer dispersal, vicariance, and extinction events. DIVA-like analysis with event counting and optimization.
