Linares-Palomino, unpub. data) The altitudinal distribution of absolute species richness in the Equatorial 3-MA manufacturer Pacific region showed more or less a constant pattern with similar values in the altitudinal bands below 1,000 m.a.s.l. (Fig. 2a; Appendix 2). In the montane altitudinal band, however, species richness decreased by about 50 species. Species richness in Ecuador peaked in the hills and decreased slightly towards the coastal lowlands and substantially towards
higher altitudes. In Peru, species richness increased from the coastal lowlands towards the sub-montane region and decreased in the montane region. The endemic species in Ecuador and Peru showed a similar pattern to overall woody species richness in each Selleck AZD1152-HQPA country (Fig. 2b; Appendix 2). Species endemic to the Equatorial Pacific region, however, increased from the lowlands to the sub-mountains, and decreased substantially in the montane region. Values of woody species density (Fig. 2c; Appendix 2) and endemic species density (Fig. 2d; Appendix 2) per 1,000 km2 of each altitudinal band, showed that there were substantially more species and endemics per unit area in the montane region than at any other altitude in Ecuador, Peru or the Equatorial Pacific region. The lowest total species and endemics density values were in the lowlands of Ecuador, Peru and the Equatorial Pacific region.

selleck chemical Number of woody (c) and endemic species (d) per 1,000 km2. Note the different y-axis scales. Solid line Pacific Equatorial region, dotted line Ecuador, dashed line Peru Total area of the geopolitical units had no effect on total vascular plant species numbers, or on woody SDF species and endemics (Pearson correlation values of 0.16, −0.20 and 0.37, respectively, all non-significant, n = 11). The total area between sea level and 1,100 m.a.s.l. had no effect on woody SDF species and endemics (Pearson correlation values of −0.13 and 0.0, respectively, all non-significant, n = 11). The analysis of species distribution by geopolitical unit showed that half of all species (51.4%) have been reported in four or less provinces or departments (13.1% in only one) (Table 2). Endemic species restricted to either Ecuador or Peru showed an extremely local distribution, 41.2 and 56.
