Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With nearly billion people as of , it accounts for about of the world's human population. Demographics of Africa, Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will exceed 3.8 billion people by 2100.

She was formerly a research associate at the Smithsonian Institution in Washington, D.C., and is based at the Michigan State University. She is associated with other major centers of research in the United States and the United Kingdom. Rasmussen's early research investigated South American seabirds and fossil birds from North America. She later specialised in Asian birds describing several new species and clarifying the status of others, particularly white-eyes and owls. More recently, she has been involved in large scale collaborations looking at patterns of global biodiversity, and has assessed the Taxonomy (biology), taxonomic status of South Asian vultures. She was the main author of ''Birds of South Asia: The Ripley Guide'', a landmark publication due to its greater geographical and species coverage compared to its predecessors. As a result of her study of m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
