Xerosere is a plant succession that is limited by water availability. It includes the different stages in a xerarch succession.Xerarch succession of ecological communities originated in extremely dry situation such as sand deserts, sand dunes, salt deserts, rock deserts etc.
Ecological succession is the process of change in the species that make up an ecological community over time. The process of succession occurs either after the initial colonization of a newly created habitat, or after a disturbance substantially alters a pre-existing habitat. [ 1 ]
Chronosequences are often used to study the changes in plant communities during succession. [4] A classic example of using chronosequences to study ecological succession is in the study of plant and microbial succession in recently deglaciated zones. For example, a study from 2005 used the distance from the nose of a glacier as a proxy for site ...
Ecological micro-succession and the competition-colonization trade-off in a bacterial meta-community on-chip.(A) sketch of a micron-scale structured bacterial environment based on microfluidics technology; (B) Fluorescent microscopy image of Escherichia coli (magenta) and Pseudomonas aeruginosa (green) inhabiting a device of the type depicted in A and which has been wettened with growth media ...
Cyclic succession is a pattern of vegetation change in which in a small number of species tend to replace each other over time in the absence of large-scale disturbance. Observations of cyclic replacement have provided evidence against traditional Clementsian views of an end-state climax community with stable species compositions .
Early ecological succession theory maintained that the directional shifts from one stage of succession to the next were induced by the plants themselves. [1] In this sense, succession theory implicitly recognized priority effects; the prior arrival of certain species had important impacts on future community composition.
For example, we can examine succession in the Loess Plateau in China. In the graph on page 995 of the paper "Plant Traits and Soil Chemical Variables During a Secondary Vegetation Succession in Abandoned Fields on the Loess Plateau" by Wang (2002), we can see the initial dominance of the Artemisia scoparia, the pioneer species.
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]
