Table 2 Hypotheses of spatial heterogeneities in abundance and distribution of hosts and vectors

From: Seasonal and spatial heterogeneities in host and vector abundances impact the spatiotemporal spread of bluetongue

  H Host Vectors Results figure
Homogeneous in hosts and vectors (4 Scenarios) H1 500 S/C 1 I in central cell Total number of hosts = 840 501 100 S/C h1=106, or h2=107 or h3=108, or h4= 109 5
Heterogeneous in hosts Homogeneous in vectors (16 scenarios) H2 Total number of hosts S≈ 840 501 Four densities of occupied cells (Figure 2): 90% OC: 554 S/OC75% OC: 666 S/OC50% OC: 1000 S/OC25% OC: 2025 S/OC 1 I in central cell H1 6 and 7
Heterogeneous in vectors Homogeneous in hosts (2 scenarios) H3 H1 100 S/C Grid divided into four sub-areas of different maximum carrying capacities (h1, h2, h3 and h4) (Figure 3a) 8
