Connell–Slatyer model of ecological succession. Ecological succession can be understood as a process of changing species composition within a community due to an ecological disturbance, and varies largely according to the initial disturbance prompting the succession. [1] Joseph Connell and Ralph Slatyer further developed the understanding of ...
A seral community is the name given to each group of plants within the succession. A primary succession describes those plant communities that occupy a site that has not previously been vegetated. These can also be described as the pioneer community. Computer modeling is sometimes used to evaluate likely succession stages in a seral community.
Ecological restoration, or ecosystem restoration, is the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed. [1] It is distinct from conservation in that it attempts to retroactively repair already damaged ecosystems rather than take preventative measures.
— Gerard Manley Hopkins' poem Inversnaid While the term "weed" generally has a negative connotation, many plants known as weeds can have beneficial properties. A number of weeds, such as the dandelion (Taraxacum) and lamb's quarter, are edible, and their leaves or roots may be used for food or herbal medicine.

Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations.
Evolutionary biology is the subfield of biology that studies the evolutionary processes ( natural selection, common descent, speciation) that produced the diversity of life on Earth. It is also defined as the study of the history of life forms on Earth. Evolution holds that all species are related and gradually change over generations. [1]
A lichen ( / ˈlaɪkən / LY-kən, UK also / ˈlɪtʃən / LITCH-ən) is a symbiosis of algae or cyanobacteria living among filaments of multiple fungi species, along with a yeast embedded in the cortex or "skin", in a mutualistic relationship. [1] [2] [obsolete source] [3] [obsolete source] [4] [obsolete source] [5] Lichens are important ...
Aristotle's biology. Among Aristotle's many observations of marine biology was that the octopus can change colour when disturbed. Aristotle's biology is the theory of biology, grounded in systematic observation and collection of data, mainly zoological, embodied in Aristotle 's books on the science. Many of his observations were made during his ...
