Table 1 Standardized regression coefficients for the best models (Δ_AICc < 2) explaining temporal β diversity in stream macroinvertebrate community composition based on Bray-Curtis dissimilarity values (average dissimilarities between consecutive years) on log(x + 1)-transformed data.

a) Dependent: Bray-Curtis dissimilarity, observed (β_obs)
Importance	BMI	Bryophytes	Simpson	Temp.	Connectivity	Gamma	adj.R²	Δ_AICc
	x	x	x	x	−0.487	x	0.201	0
	0.178	0.213	0.178	0.227	0.777	0.185
b) Dependent: Bray-Curtis dissimilarity, departure from null (β_dep)
Importance	BMI	Bryophytes	Simpson	Temp.	Connectivity	Gamma	adj.R²	Δ_AICc
	x	−0.606	x	x	0.379	x	0.354	0
	x	−0.525	x	x	x	x	0.241	1.870
	0.252	0.901	0.314	0.257	0.524	0.195

Dependent variables are (a) observed dissimilarity (β_obs) and (b) departure of the observed dissimilarity from the null expectation (β_dep). x Denotes that a variable was not included in that model. The overall importance across all candidate models is also presented for each predictor; the highest importance value is given in bold. BMI = bed movement intensity, Temp = water temperature.
