The book does not describe the individual Endemic Bird Areas in detail; a subsequent more detailed publication, Endemic Bird Areas of the World: Priorities for Biodiversity Conservation does so, however. The book is 90 pages long. It has a foreword by Edward O. Wilson.
Human activities have led to an ongoing biodiversity loss and an accompanying loss of genetic diversity. This process is often referred to as Holocene extinction , or sixth mass extinction . For example, it was estimated in 2007 that up to 30% of all species will be extinct by 2050. [ 4 ]
A variety of objective means exist to empirically measure biodiversity. Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness ...
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
[7] [8] It is the primary application for crowd-sourced biodiversity data in places such as Mexico, southern Africa, and Australia, [9] [10] [11] and the project has been called "a standard-bearer for natural history mobile applications." [12] Most of iNaturalist's software is open source. [13]
Life restoration of a feeding individual. Genyornis newtoni was a medium-sized dromornithid with a robust body, measuring up to 2.15 metres (7.1 ft) tall and weighing around 250–350 kilograms (550–770 lb), though body mass estimation may vary based on different methods. [6]
Human activities have affected the biodiversity of the fauna. The Asiatic lion and cheetah, Caspian tiger and leopard (subspecies P. p. nimr and P. p. tulliana) used to be present, but they have died out in the country, and so the brown bear and the gray wolf are the largest carnivores remaining.
The Tropical Andes are a biodiversity hotspot named the "global epicentre of biodiversity" according to the Critical Ecosystem Partnership Fund. [citation needed] The Tropical Andes is an area of rich biodiversity. This location contains about 45,000 plant species of which 20,000 are endemic.
