TLDR
The number of known species in the world is conservatively estimated at 1·5 million; six-times higher than hitherto suggested; this realization has major implications for systematic manpower, resources, and classification.

Estimating Terrestrial Biodiversity through Extrapolation

TL;DR: The importance of using 'reference' sites to assess the true richness and composition of species assemblages, to measure ecologically significant ratios between unrelated taxa, toMeasure taxon/sub-taxon (hierarchical) ratios, and to 'calibrate' standardized sampling methods is discussed.
Journal ArticleDOI

Phylogenetic relationships among ascomycetes: evidence from an RNA polymerse II subunit.

TL;DR: Findings show that a slowly evolving protein-coding gene such as RPB2 is useful for diagnosing phylogenetic relationships among fungi, and suggests that fruiting body formation and forcible discharge of ascospores were characters gained early in the evolution of the Ascomycota.
Journal ArticleDOI

How Many Species Are There on Earth and in the Ocean

TL;DR: It is shown that the higher taxonomic classification of species follows a consistent and predictable pattern from which the total number of species in a taxonomic group can be estimated, and when applied to all domains of life, it predicts ∼8.7 million eukaryotic species globally.
Journal ArticleDOI

The future of biodiversity.

TL;DR: For example, the authors showed that if all species currently deemed "threatened" become extinct in the next century, then future extinction rates will be 10 times higher than recent rates in well-known, but taxonomically diverse groups from widely different environments.
Journal ArticleDOI

The magnitude of fungal diversity: the 1.5 million species estimate revisited

TL;DR: The number of known species of fungi is estimated as at least 74 K, but could be as much as 120 K with allowances for ‘orphaned’ species as discussed by the authors, which is the current working hypothesis for the number of fungi on Earth.

Flora of the British Isles

TL;DR: The classification of families and abbreviations of Pteridophyta, Gymnospermae, Angiospermaes, Dicotyledones, Monocotylingones and other life forms are summarized in this monograph.

Fungi on Plants and Plant Products in the United States

TL;DR: The heterosis estimaríon for each genetic group was performed once orthogonal contrasts between genetíc groups were made in each one the caracteristlCs that produced signif¡cant effects, except for weaning age.
Journal ArticleDOI

How many species are there on Earth

TL;DR: Current answers to the factual question posed in the title are surveyed and the kinds of information that are needed to make these answers more precise are reviewed.
