Primed and cued: long-term acoustic telemetry links interannual and seasonal variations in freshwater flows to the spawning migrations of Common Snook in the Florida Everglades

Table 1 Model selection results based on lowest AIC value from GLMM models examining the drivers of annual migratory intensity (migratory primers) for Common Snook

Hypothesized driver	Model variables	df ^†	AIC	ΔAIC ^‡	AIC Weight	Conditional R²	Marginal R²
Flow dynamics	Minimum water level	3	364.3	13	0.001	0.175	0.122
	Drydown duration	3	359.4	8.1	0.017	0.204	0.135
Other hydrologic/abiotic conditions	Maximum temperature	3	379	27.7	< 0.001	0.079	0.048

Fish size	Fish size	3	372.6	21.3	< 0.001	0.151	0.085
Global model	Minimum water level + drydown duration + maximum temperature + salinity range + fish size	10	357.9	6.6	0.035	0.299	0.234
Best model	Drydown duration + fish size	4	351.3	0	0.947	0.276	0.197

The response variable for models is whether each individual fish was detected migrating or not migrating each year, across all eight years of tracking. For variable descriptions see Additional file 1: Table S1
