- The numbers of fungi: contributions from traditional . . .
The global diversity of fungi has been estimated using several different approaches There is somewhere between 2–11 million estimated species, but the number of formally described taxa is around 150,000, a tiny fraction of the total In this paper, we examine 12 ascomycete genera as case studies to establish trends in fungal species descriptions, and introduce new species in each genus To
- Recent responses to climate change reveal the drivers of . . .
Specifically, minimum changes were estimated by subtracting the current value of Bio5 at the species’ current warmest site in their geographic range (i e , at the time of the resurvey) from the projected Bio5 (for 2070) at the coldest site in their current range We assumed that species are potentially able to survive the minimum change in
- Outer space - Wikipedia
In the case of Earth this includes all space from the Earth to a distance of roughly 1% of the mean distance from Earth to the Sun, [130] or 1 5 million km (0 93 million mi) Beyond Earth's Hill sphere extends along Earth's orbital path its orbital and co-orbital space
- Atmosphere of Earth - Wikipedia
Total atmospheric mass is 5 1480 × 10 18 kg (1 13494 × 10 19 lb), [36] about 2 5% less than would be inferred from the average sea-level pressure and Earth's area of 51007 2 megahectares, this portion being displaced by Earth's mountainous terrain Atmospheric pressure is the total weight of the air above unit area at the point where the
- Tropical forests are home to over half of the world’s . . .
Of the Earth’s estimated 8 7 million species (Mora et al 2011), a mere 1 3% (n = 116,000) have been assessed comprehensively (IUCN 2020), and for terrestrial species within this minuscule group, only the ranges of mammals, birds, amphibians, and reptiles have been described Other major taxonomic groups (eg vascular plants, invertebrates
- The global biomass and number of terrestrial arthropods
Similarly, we estimate the total number of terrestrial arthropods at about 1 × 10 19 individuals (uncertainty range, 0 5 × 10 19 to 2 × 10 19), which agrees with the range of 10 17 to 10 19 individuals estimated by Williams in the 1960s, based on limited data from U K soils Fig 5 The global biomass of terrestrial arthropods
