Seed dispersal as a search strategy: dynamic and fragmented landscapes select for multi-scale movement strategies in plants

Table 1 Parameter ranges used in the different simulation scenarios. Landscape size 512 × 512 grid cells (1 cell can hold one individual)

Landscape parameters	Parameter values
Patch size [diameter, # grid cells]	1, 2, 4, 8, 16, 32, 64, 128, 256, continuous
Inter-patch distance^a [# grid cells]	2, 4, 16, 64, 256, 1024
Patch turnover rate	0, 0.01, 0.05, 0.1, 0.5, 1
Dispersal parameters	Parameter values
Dispersal kernel (Pareto scale parameter μ)	U^b, 1.1,1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, MN^c
Number of seeds per individual^d	(10), 100, (1000), (10000)

^a IPD is calculated as mean free path, see appendix S2
^b Alternative (‘benchmark’) kernel 1: uniform dispersal
^c Alternative (‘benchmark’) kernel 2: Moore neighbourhood dispersal
^d Number of seeds per individual was 100 in main simulations; 10, 1000, 10,000 were used in sensitivity analyses only
