Figure 1 in A completely resolved phylogenetic tree of British spiders (Arachnida: Araneae)
Figure 1. Fully resolved phylogenetic tree of the British spider species. All non-British spider families with European representatives are included for reference, and the tree is rooted using Liphistiidae as the outgroup. Branch lengths are arbitrary and do not indicate the timing or degree of divergence. For readability, species from the same family are shown in the same colour.
Figure 3 in A completely resolved phylogenetic tree of British spiders (Arachnida: Araneae)
Figure 3. Selected ecological and conservation biological variables mapped onto the phylogenetic tree of British spiders. The abundance indicates the number of occupied hectads, with a 1% depreciation per year since the latest record. The recency of the observations is indicated as the median year of the latest record per hectad. The northern distribution is indicated by the median distance of the occupied hectads from the southern edge of the British Ordnance Survey national grid. The Vulnerability Index is 1 minus the quantile of the average of the recency quantile and the abundance quantile for each species. Higher values indicate species that are reported from only a small number of hectads and have few or no recent records; low values indicate species that are widespread and have often been recorded recently. The Contraction Index is the quantile of the difference between the abundance and recency quantiles. Higher values indicate widespread species with relatively few recent records; low values indicate highly localised species that have nevertheless a large fraction of recent records (e.g., new arrivals and expanding species). The clades highlighted in colour are discussed in more detail in the text. The order of columns (from left to right) follows the order of the legends (from top to bottom). Based on data provided by the UK Spider Recording Scheme.
