Canadian Biodiversty: Species - Amphibians 42 2 . Reptiles 42 0 . Birds : 426 0 . Mammals : 194 0 ... (see the Patterns of Biodiversity section for more information on biological surveys). The ideal distribution maps would be a regular grid with the abundance of every species in every grid space clearly marked. Unfortunately, none of the maps that are in this section are of this type, and there are extremely few of these

Species distribution - Wikipedia - Species distribution —or species dispersion — is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a s of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a

The History of Animal Evolution - University of Waikato - The evolution of amphibians. By the Devonian period two major animal groups dominated the land: the tetrapods (4-legged terrestrial vertebrates) and the arthropods, including arachnids and wingless insects. The first tetrapods were amphibians, such as Ichthyostega, and were closely related to a group of fish known as lobe-finned fish Eusthenopteron

Global patterns in biodiversity | Nature -  · To a first approximation, the distribution of biodiversity across the Earth can be described in terms of a relatively small number of broad-scale spatial patterns. Although these patterns are

Africa - People | Britannica - Africa - Africa - People: Africa is now widely recognized as the birthplace of the Hominidae, the taxonomic family to which modern humans belong. Archaeological evidence indicates that the continent has been inhabited by humans and their forebears for some 4,000,000 years or more. Anatomically modern humans are believed to have appeared as early as 200,000 years ago in the eastern region of

Ecosystems | National Climate Assessment - As temperatures rise and precipitation patterns change, many fish species (such as salmon, trout, whitefish, and char) will be lost from lower-elevation streams, including a projected loss of 47% of habitat for all trout species in the western by 2080. 9 Similarly, in the oceans, transitions from cold-water fish communities to warm-water communities have occurred in commercially important
