Available tools
- Aquatic Drift Sample Filtered Volume Term Tool Multiply explicitly supplied mean filtered volume flow by sampling duration without estimating net efficiency or drift abundance.
- Community Composition One Species Turnover Tool One species share change and raw Bray-Curtis numerator contribution, not a whole-community dissimilarity index.
- Community Rare Count Share Tool Use an explicit count cutoff for rarity bookkeeping; zero-count taxa are excluded from rare taxa.
- Community Total Support Count Tool Calculate community total support count from explicit caller-supplied inputs.
- Decomposition Mesh Exclusion Label Tool Preserve explicit decomposition mesh and exclusion-convention metadata without inferring organism access or decomposition effects.
- Ecological Asymmetry Interaction Pair Compare two explicitly directional interaction effects on a common measurement basis without inferring ecological mechanisms.
- Ecological Efficiency Trophic Transfer Term Tool Separate matched-period trophic, assimilation and production efficiency ratios; boundaries must be defined consistently by the caller.
- Ecological Effort Normalized Count Normalize an explicit ecological count by compatible observed effort without correcting detectability.
- Ecological Effort Zero Exposure Flag Tool Preserve an undefined zero-effort rate using an explicit flag and zero placeholder.
- Ecological Metabolism Body Mass Exponent Term Tool Reference-normalized allometric metabolic rate with an explicit fitted exponent, not a universal quarter-power law.
- Ecological Network Edge Evidence Token Tool Encode an ordered explicit ecological-network edge and evidence reference without inferring interaction direction or strength.
- Ecological Plot Effective Area Tool Subtract explicitly supplied exclusion areas with a caller-verified overlap correction.
- Ecological Stoichiometry Cnp Molar Factor Tool C:N:P mole quantities and P-normalized ratios from explicitly supplied elemental masses and molar masses; no ecological reference ratio is selected.
- Ecological Time Support Gap Tool Sum explicitly nonoverlapping temporal sampling cells; overlapping input records are not merged.
- Ecological Trait Abundance Contribution Return one explicit abundance-weighted trait contribution without aggregating or imputing other taxa.
- Ecological Trait Unit Source Pair Tool Preserve an explicit ecological trait unit and source without converting dimensions or assigning trait values.
- Ecosystem Pool Transfer Mass Balance Term Tool Reconcile explicit ecosystem pool transfers and separate losses on one mass basis without predicting turnover or clipping negative discrepancies.
- Field Observation Visibility Weight Apply an explicitly supplied visibility weight without estimating detection probability or inverse-probability correction.
- Food Web Link Direction Tag Orient one explicitly identified food-web link from resource to consumer without inferring feeding relationships.
- Gapfraction Canopy Interception Point Tool Calculate explicit canopy point-sampling gap and intercepted fractions without converting to leaf-area index.
- Leaflitter Decay Single Interval Factor Tool Calculate a supplied litter dry-mass remaining fraction and apparent single-interval exponential decay constant, preserving negative values for mass gain.
- Litter Decay Rate Two Mass Term Tool Exponential two-point decay from ash-free dry masses; strictly positive decay is required for a finite positive half-life.
- Litter Mass Blank Loss Term Tool Subtract the supplied blank mass loss while retaining signed results.
- Lotka Volterra Competition One Term Tool One continuous Lotka-Volterra competition rate with an explicit cross-species load coefficient; no equilibrium or fitted parameter inference.
- Net Primary Production Gross Respiration Gap Tool NPP and ecosystem production with respiration treated as nonnegative outgoing carbon flux, all on matched area/time bases.
- Nutrient Resorption Mass Loss Correction Term Tool Nutrient resorption with an explicit senescent-to-green dry-mass retention correction; negative efficiencies remain visible.
- Observation Effort Offset Factor Tool Show a constant-observation-rate effort normalization scenario without claiming effort-invariant ecological abundance.
- Occupancy Detection Non Detection Code Encode explicit survey and detection flags without treating nondetection as species absence.
- Patch Colonization Extinction One Step Term Tool Explicit Euler step of the Levins colonization-extinction model; out-of-range next fractions expose an excessive supplied time step.
- Phenology Event Circular Day Gap Tool Cyclic ordinal-day difference in an explicit period, with a half-period tie retained positive; no hemisphere or season is inferred.
- Plot Sampling Fraction Weight Tool Return area sampling fraction and inverse expansion weight under an explicit equal-inclusion area design assumption.
- Population Doubling Discrete Growth Factor Tool Positive discrete annual growth and doubling time under a constant supplied fractional growth rate.
- Quadrat Cover Class Midpoint Return the midpoint of caller-supplied cover-class bounds without looking up or selecting a cover classification.
- Quadrat Edge Individual Inclusion Rule Tool Apply an explicit quadrat edge-inclusion policy to supplied location flags without detecting organisms or selecting survey protocol.
- Sample Pseudo Replicate Group Flag Flag distinct sample identifiers sharing an explicit sampling-unit identifier without deciding statistical independence.
- Seed Rain Trap Edge Adjustment Tool Calculate seed rain trap edge adjustment from explicit caller-supplied inputs.
- Seedrain Density Trap Area Time Factor Tool Calculate seedrain density trap area time factor from explicit caller-supplied inputs.
- Species Area Power One Scale Factor Tool Reference-normalized species-area power relation using a supplied exponent, returning an expectation without species-count rounding.
- Species Interaction Observation Duration Tool Measure one explicitly supplied ordered species-interaction observation duration without identifying species or inferring interaction effects.
- Species Niche Axis Overlap Intersect two explicit closed niche-axis ranges and report their enclosing span without modeling a multidimensional niche.
- Trait Weight Missing Share Tool Calculate trait weight missing share from explicit caller-supplied inputs.
- Trophic Transfer Reference Base Tool Calculate trophic transfer reference base from explicit caller-supplied inputs.
