Traits with their allometric function and corresponding parameters in ADBM

Traits (Unit)	Allometric function	Parameters	Comments
Energy $\left(\text{Joules}\right)$	$E_i=e{M}_i$	$e$	Arbitrary. No effect on structure a
Abundance $\left(\text{individual}/{\mathrm{m}}^2\text{or}\text{individual}/{\mathrm{m}}^3\right)$	$N_i=n{M}_i^{n_i}$	$n$	Connectance affected by the product $\mathit{nah}$ a
		$n_i$	Assumed value of $\frac{‐3}{4}$ based on empirical data
Space Clearance Rate $\left({\mathrm{m}}^2/\mathrm{s}\text{or}{\mathrm{m}}^3/\mathrm{s}\right)$	$A_{\mathit{ij}}=a{M}_i^{a_i}{M}_j^{a_j}$	$a$	Connectance affected by the product $\mathit{nah}$ a

		$a_j$	Estimated using ABC
Handling time $\left(\mathrm{s}\right)$	$H_{\mathit{ij}}=\frac{h}{b‐\frac{M_i}{M_j}}\text{if}\frac{M_i}{M_j}<b$ $H_{\mathit{ij}}=\infty \text{if}\frac{M_i}{M_j}\ge b$	$h$	Connectance affected by the product $\mathit{nah}$ a
		$b$	Estimated using ABC
