In ecology regeneration is the ability of an ecosystem – specifically, the environment and its living population – to renew and recover from damage. It is a kind of biological regeneration . Regeneration refers to ecosystems replenishing what is being eaten, disturbed, or harvested.
Regeneration tissues that are cut from the gastric region contain polarity, which allows them to distinguish between regenerating a head in the apical end and a foot in the basal end so that both regions are present in the newly regenerated organism. [68] Head regeneration requires complex reconstruction of the area, while foot regeneration is ...
Limb regeneration occurs when a part of an organism is destroyed, and the organism must reform that structure. The general steps for limb regeneration are as follows: epidermis covers the wound which is called the wound healing process, [ 10 ] the mesenchyme dedifferentiates into a blastema and a apical ectodermal cap forms, and the limb re ...
A classic example being the continuous replacement of blood cells. A fourth type of regeneration is compensatory regeneration or Compensatory hyperplasia, where existing tissue will proliferate and regenerate damaged or missing tissue without the use of stem cells or previous adult cells undergoing dedifferentiation before dividing. As such, no ...
Biogeographic realms are characterized by the evolutionary history of the organisms they contain. They are distinct from biomes, also known as major habitat types, which are divisions of the Earth's surface based on life form, or the adaptation of animals, fungi, micro-organisms and plants to climatic, soil, and other conditions
Reinforcement is the deliberate introduction and integration of an organism into an area where its species is already established. [1] This mode of translocation is implemented in populations whose numbers have dropped below critical levels, become dangerously inbred, or who need artificial immigration to maintain genetic diversity. [15]
The Society for Ecological Restoration defines restoration as "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed." [1] Restoration ecology is the academic study of the science of restoration, whereas ecological restoration is the implementation by practitioners. [21]
Bioturbation is thought to have been an important co-factor of the Cambrian Explosion, during which most major animal phyla appeared in the fossil record over a short time. [2] Predation arose during this time and promoted the development of hard skeletons, for example bristles, spines, and shells, as a form of armored protection. [2]
