Biodiversity databases store taxonomic information alone or more commonly also other information like distribution (spatial) data and ecological data, which provide information on the biodiversity of a particular area or group of living organisms. They may store specimen-level information, species-level information, information on nomenclature ...
The reserve includes both dry Chihuahuan Desert shrublands and forested sky island, high-elevation enclaves of Sierra Madre Oriental pine-oak forest. The reserve is home to 400 bird species and 70 mammal species, including the American black bear ( Ursus americanus ), collared peccary ( Pecari tajacu ), and cougar ( Puma concolor ).
Johnny Castaway is a screensaver released in 1992 by Sierra On-Line/Dynamix, and marketed under the Screen Antics brand as "the world's first story-telling screen saver". The screensaver depicts a man, Johnny Castaway, stranded on a very small island with a single palm tree. It follows a story which is slowly revealed through time.
California has two high deserts: the Mojave Desert and the Great Basin Desert. The Mojave Desert ecoregion is marked by the presence of Joshua trees. [3] The dry cold Great Basin desert of California consists of the Owens Valley, and is classified into Great Basin shrub steppe by the WWF, [4] and into the Central Basin and Range ecoregion by ...
The Nama Karoo of Namibia has the world's richest desert fauna. [8] The Chihuahuan desert and Central Mexican matorral are the richest deserts in the Neotropics. [9] The Carnarvon xeric shrublands of Australia are a regional center for endemism. [1] The Sonoran and Baja deserts of Mexico are unusual desert communities dominated by giant ...
The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex. The combination of climate , topography , moisture , and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet (200 to 4,400 m).
The word desert has been "formerly applied more widely to any wild, uninhabited region, including forest-land", and it is this archaic meaning that appears in the phrase "desert island". [3] The term "desert island" is also commonly used figuratively to refer to objects or behavior in conditions of social isolation and limited material means ...
Island ecology is the study of island organisms and their interactions with each other and the environment. Islands account for nearly 1/6 of earth’s total land area, [1] yet the ecology of island ecosystems is vastly different from that of mainland communities. Their isolation and high availability of empty niches lead to increased speciation.
