Evolution and Speciation in Fungi and Eukaryotic Biodiversity. 2025. 94 figs .(b/w). 306p. gr8vo. Paper bd.

For 2,056,907 eukaryotic species, this book elaborates the role played by environmental factors (i) spatial distribution, (ii) light-temperature, (iii) precipitation-liquid water and biological attributes, (iv) cellularity, (v) symmetry, (vi) clonality, (vii) sexuality, (viii) modality and (ix) motility that either accelerate or decelerate biodiversity. About 20 and 80% eukaryotes are aquatics and terrestrials. Decreasing light intensity and temperature reduce diversity from the equator toward the polar zones. Water availability also reduces the diversity from 5.4 - 65.5 species/km2 in tropical evergreen forests to < 0.0045 species/km2 in deserts and polar zones. Unicellularity and radial symmetry decelerate the diversity to < 2 and < 26%, respectively. Increase in tissue types from < nine in lower eukaryotes to > 200 in mammals reduces clonality from 100 to 0%. Strategies developed by eukaryotes reduce selfing by < 24% in plants and < 1% in metazoans.
