Interspecies Communication

Separate evolved signalling from useful by-products.

Trace who produces and who detects an event.

Compare a response with background environmental changes.

Locate the species boundary in an interaction.

State which observation would support or weaken a claim.

Define actions without guessing feelings or motives.

Choose what to count and when to observe.

Record the interval between event and response.

Compare settings, prior exposure and individual behaviour.

Check whether two observers code the same event alike.

Follow detection from physical input to response.

Compare species-specific spectral sensitivity.

Distinguish airborne sound from substrate motion.

Connect concentration, receptor binding and discrimination.

Predict which features two species can detect differently.

Track how the detectable signal changes in transit.

Compare visibility, airflow and acoustic conditions.

Test whether combined channels add or repeat information.

Relate response differences to hunger, attention and experience.

Distinguish missed events from absent communication.

Predict a visible response without assigning human words.

Record natural calls, head turns and habitat context.

Compare response counts during call and quiet periods.

Check visibility, simultaneous movement and sampling choices.

Revise a prediction and choose another undisturbing observation.
