As adopted for the remnants, to facilitate comparison (the odds ratios are listed in Table four). Many species were far much less prevalent in plantings than remnants: There have been 13 species with ten presence (coded blue or green), and we therefore excluded assessment of any associations with them. Conversely, we note that 10 species were additional common in plantings than in remnants, including the excellent fairy-wren Malurus cyaneus (Ref 30), which was present 61 from the time in plantings compared with 13 in remnants. In contrast to the remnants, the plantings have been characterized by no clusters of species and far fewer associations. Eight in the indications shown in Fig. 1 amongst species not uncommon in either habitat will not be apparent in Fig. two, compared with only 1 new indication in Fig. 2. Six in the missing indications were from the white-plumed honeyeater or willie wagtail (Refs 34 and 37), both of which had been far more prevalent in plantings (75 and 79 on plantings, respectively, compared with 57 and 61 on remnants).Woodland remnantsWe present an PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21343449 ZL006 web association diagram for the 795 surveys in woodland remnants (Fig. 1). The nodes within the association diagram represent the 38 species that occurred in at least 10 of field surveys at these sites, with every single species offered a reference quantity (Table two). We recorded the presence of yet another 118 species, ranging in rarity from 50 species recorded 5 instances or fewer in the entire study (0.three presence) to some with just much less than 10 presence. The arrowed lines indicate the strength and path of indications (red, representing an odds ratio 3) and contraindications (blue, representing an odds ratio ). For example, the strongest indication was that with the whiteplumed honeyeater Lichenostomus penicillatus (Ref 34) by the dusky woodswallow Artamus cyanopterus (Ref 11). The odds ratio is 13.1, because the white-plumed honeyeater was identified at 57 of all web sites, compared with 95 in the web pages where the dusky woodswallow was identified. In contrast, there was “perfect” contraindication (black line) among the grey butcher-bird Cracticus torquatus (Ref 14) and restless flycatcher Myiagra inquieta (Ref 25), for the reason that these two species under no circumstances co-occurred. The arrangement from the nodes in Fig. 1 shows a cluster of nine species, all of that are positively associated with at least half the other species inside the cluster.
