Abstract

Example ontology of fish migration causation (cf. Figure 2).

Causal-like relationships amongst states, events, and processes, after Galton (2012).

Pictorial illustration of a subset of the raw fish data. Each horizontal line represents a single fish. Each dot along the horizontal lines represent a day. The colors of the dots indicate different river zones in which the specific fish was located each day. Fish movement occurs when the horizontal line changes its color, i.e., in the sixth line the fish moves from river zone blue to river zone orange, stays there for 2 days and moves on to river zone pink.

Summary of expected and observed frequency of general movement (me), or specific upstream (ue) or downstream (de) movement following water temperature (wt, equal intervals from wt1e (<10◦C) to wt5e (>25◦C)), river flow (rf , first quartile rf 1e to fourth quartile rf 4e), or moon phase (mp, full moon fme, new moon nme, first quarter fqe, last quarter lqe) events within 2 days.

Summary of expected and observed frequency of movement with revised classification of water temperature (wt), highlighting the biologically significant temperature range 16–23◦C (wt3e).

Summary of expected and observed frequency of general movement (me), or specific upstream (ue) or downstream (de) movement co-occurring with specified water temperature (wt, equal intervals from wt1e (<9◦C) to wt4e (>23◦C)), river flow (rf , first quartile rf 1e to fourth quartile rf 4e) states, persisting for more than 2 days.
