Evidence disagreement map
Research can look contradictory when studies use different endpoints, life stages, environments, exposures, methods or taxon identities. These comparison sets show which differences can coexist and what remains unresolved.
This map does not vote for a winner. A reconciliation explains why results may be compatible. It does not average unlike measurements, manufacture consensus or lift any source beyond its own claim boundary.

Different endpointDifferent exposureDifferent life stage
Question: Why can warmer water appear helpful in one study and harmful in another?
Shorter incubation, altered growth, delayed maturation, suppressed reproduction and changed sex allocation can all be reported as a temperature effect, even though they are not the same outcome.
4 evidence records compared. The corpus does not establish one universal aquarium optimum, a lifetime safe interval or how commercial lines differ across complete life cycles.
Different endpointDifferent environmentDifferent method
Question: How can shrimp reduce attached algae while some system measurements rise?
A reader may treat fewer algal cells, lower leaf-periphyton chlorophyll, faster litter breakdown and higher water-column nutrients as competing verdicts on whether shrimp make a system clean.
3 evidence records compared. The corpus does not provide a home-aquarium cleaning rate, a stocking rule for algae control or a nutrient budget that transfers across tanks.
Different endpointDifferent environmentDifferent methodTaxon identity
Question: Do environmental colour effects conflict with genetic pigmentation findings?
Background and diet studies show measurable appearance changes, while molecular studies identify pigmentation pathways and market labels imply inherited lines.
5 evidence records compared. The corpus cannot map every named trade line to a validated genotype, predict offspring from seller labels or separate all environmental and inherited contributions from a photograph.
Different endpointDifferent life stageDifferent methodDifferent environment
Question: Why do feeding studies appear to identify different best foods?
Studies report colour, growth, female reproduction, offspring quality or short-term survival under different feeds, and each positive result can be retold as proof of a universally superior food.
4 evidence records compared. The corpus does not establish one complete diet, universal portion, feeding frequency or long-term product ranking across lines and colony conditions.
Different endpointDifferent exposureDifferent methodTaxon identity
Question: Why do chemical studies show responses without yielding one safe aquarium number?
Mortality, enzyme activity and transcript abundance may change at different concentrations and times, tempting readers to interpret the lowest observed response or a no-death result as a universal safety line.
2 evidence records compared. The corpus does not establish a universal home-aquarium copper threshold, product-dose rule, antidote or chronic no-effect level for every water chemistry and line.
Taxon identityDifferent method
Question: Why can older and newer sources use different names for apparently related shrimp?
Older field records, morphology-based revisions, mitochondrial barcodes and integrative taxonomic studies may place similar-looking material under different names or lineages.
4 evidence records compared. The corpus does not resolve every Neocaridina species treatment, authenticate commercial animals from a photograph or make one barcode a universal identity test.
