FIGURE 1 in The Encyclopedia of Life vs. the Brochure of Life: Exploring the relationships between the extinction of species and the inventory of life on Earth
FIGURE 1. Total number of species described after 25 years, expressed as a percentage of the remaining total number of species (y axis), for different rates of discovery of new species (x axis; current values, 1 = 10,000 species/year). Three estimates of the total number of species living in year 2000 are considered: a very low estimate, 3 million (white rectangles), a middle estimate, 10 million (grey rectangles) and a high estimate, 100 million (black rectangles); in all cases, the number of species described up to year 2000 is estimated to be 1.5 million. Only if total biodiversity is very low and rates of discovery are 10 times current values (or higher), can the Encyclopedia of Life be totally accomplished in 25 years (% Described = 100; note the exclamation symbols, '!').
FIGURE 2 in The Encyclopedia of Life vs. the Brochure of Life: Exploring the relationships between the extinction of species and the inventory of life on Earth
FIGURE 2. Relationships between the rate of description of new species ('Discovery', left axis; current values, 1 = 10,000 species/ year; logarithmic scale), the time needed to describe all the species at that rate ('Time', right axis; in years; logarithmic scale), and the number of species that are lost to extinction during this time ('Biodiversity loss', horizontal axis; logarithmic scale). Three estimates of the total number of species living in year 2000 are considered: a very low estimate, 3 million (thin curves); a middle estimate, 10 million (dotted curves), and a high estimate, 100 million (thick curves). For each case, two curves are shown: discovery rates (D curves, like, D3 for 3 million species or D100 for 100 million) and time to complete the Encyclopedia of Life (i.e., time to extinction of the species indicated in the horizontal axis; t curves, like t10 for 10 million). Vertical and horizontal dotted lines are used in the figure as an example and evidence that, if the total number of species existing in year 2000 is estimated in 10 million (dotted curves), ca. 106 species (point a) will be lost during the completion of the Encyclopedia (in a time span above 100 years, point b) if we work at a rate of discovery close to 7 times the current one (point c).

Figure 12 in The Miocene tortoise Testudo catalaunica Bataller, 1926, and a revised phylogeny of extinct species of genus Testudo (Testudines: Testudinidae)
Figure 12. Phylogenetic tree of Testudo spp. included in this study, based on the most parsimonious cladogram depicted in Figure 11 and further indicating the approximate stratigraphical range of the depicted taxa. Age boundaries (in million years ago or mega-annums, Ma) for epochs, stages, European land mammal ages (ELMA) and Mammal Neogene units (MN) are based on Hilgen, Lourens & Van Dam (2012; see this reference for the full name of stages and ELMA abbreviated in this figure). For illustration purposes, divergence times are arbitrarily set one million years before the oldest record of each clade. Similarly, successive branching points within ghost lineages are separated by one million years to avoid their collapse in the figure. For full taxon names, see Table 3.
