Sand dune ecology describes the biological and physico-chemical interactions that are a characteristic of sand dunes. Sand dune systems are excellent places for biodiversity, partly because they are not very productive for agriculture, and partly because disturbed, stressful, and stable habitats are present in proximity to each other.
A psammosere is an intermediate stage in ecological succession, known as a seral community, that begins life on newly exposed coastal sand. The most common psammoseres are sand dune systems. Psammosere is a form of xerosere succession, meaning it begins in an environment with limited to no freshwater availability. [2]
In Dune, the desert of Arrakis is the only known source of the spice melange, the most essential and valuable commodity in the universe. Used as a drug, melange lengthens life span, increases vitality, and heightens awareness. It can also unlock prescience in some subjects, which makes safe and accurate interstellar travel possible. The ...
He first published this work as a paper in the Botanical Gazette in 1899 ("The ecological relations of the vegetation of the sand dunes of Lake Michigan"). [12] In this classic publication and subsequent papers, he formulated the idea of primary succession and the notion of a sere —a repeatable sequence of community changes specific to ...
The dunes are believed to be remnants of a massive lake, Laka Alamosa, that dried up roughly 440,000 years ago, according to the park’s website.Over time, the park says wind, water and sediment ...
Coastal sand dunes can provide privacy and/or habitats to support local flora and fauna. Animals such as sand snakes, lizards, and rodents can live in coastal sand dunes, along with insects of all types. [45] Often the vegetation of sand dunes is discussed without acknowledging the importance that coastal dunes have for animals.
On a nearby sand dune, researchers found 10 lizards with a unique pattern, the study said. They took a closer look and realized they’d captured a new species: Eremias graphica, or the ...
Many inland eolian dunes are present in North America, including vegetated (stabilized) eolian dunes of the U.S. Atlantic Coastal Plain, dunes of Laurentian Great Lakes region, dunes of the Central and Southern Great Plains, the Nebraska Sand Hills, White Sands (New Mexico), Great Sand Dunes (Colorado), dunes of the southern Colorado Plateau, and dune fields of the Southwest Deserts.
