Advantages of Cast In Situ Concrete Piles As explained above cast in situ piles are installed by pre-excavation, thus eliminating vibration due to driving as in case of driven piles. Finally it may refer to captive breeding of wildplants or animals in zoos or other situations far removed from their indigenous environment. Ex-situ conservation of biodiversity involves the breeding and maintenance of endangered species in artificial ecosystems such as zoos, nurseries, botanical gardens, gene banks, etc. The life cycles of the organisms and their evolution progresses in a natural way. 2. Seed Banks : Problems. It is used to refer to the collection and freezing in liquid nitrogen of animalgenetic resources in the form of living semen, ova or embryos. It is not as disruptive as ex situ conservation, i.e. Or will we finally pull together to take care of what's left of our planet. 3) Advantages of in situ and ex situ conservation. Advantages: Not time dependent It is less disruptive than removing organisms from their habitats. In-situ conservation provides the required green cover and its associated benefits to our environment. In-situ conservation provides the required green cover and its associated benefits to our zoos. If any disease or sickness appears among the animal species, they can be quickly addressed. Another benefit is that this strategy helps ensure the ongoing processes of evolution and adaptation within their environments. The flora and fauna live in natural habitats without human interference. The chances of the population recovering are greater than ex situ methods. Is humanity doomed?

Ex-situ conservation involves the conservation of genetic resources of species away from their area of origin or development. The advantages of in-situ conservation can be summed up as follows: (1) In-situ conservation is a cheap and convenient way of conserving biological diversity as we play a supportive role only. organisms are protected from predation and poaching health of the individuals can be monitored and medical assistance given as required populations can be divided so if disaster strikes one population, the other population can survive The major ADVANTAGES for in situ conservation relate to the availability of technologies and the utilization of the breeds. It may also be the preservation ofDNA segments in frozen blood or other tissues. Preliminary multiplication 39 ... take advantage of plant genetic resources inasmuch as they are useful to us, which means that we must understand them, and know how to manage, In-situ conservation, which is also known as "on-site conservation", refers to the conservation of wild species in their natural habitats and environment. It doesn’t involve removing species from their natural ecosystems. Factors detrimental to the existence of the species concerned are eliminated and the species is allowed to grow in its natural environment in which it has been growing since a long time. Is there an alternative for coal? It is applied to conservation of agricultural biodiversity in agroecosystems by farmers, especially those using unconventional farming practices. 3) Live conservation programmes may survive major political or environmental upheaval, wars, or climatic disasters that could eliminate frozen stores, especially those needing imported frozen nitrogen. This is an advantage for animals living in ex situ conservation environment. Advantage: can save large variety of plant species in a very small space. ecological integrity is maintained.

In situ (conservation in the original habitat) is a priority and an advantage over ex situ (non-habitat conservation) methods. It involves protection of larger populations and conservation of organisms and their habitat as a … Exeter/Imperial/Kent/UEA? Plants and animals conserved in their natural environment; Biodiversity permanently protected; Representative examples of ecosystems also permenantly protected; Natural and cultural heritage protected permenantly; Ecological integrity is maintained and managed 5) This method of conservation also allows populations to adapt to changing environmental conditions and endemic diseases. Finally, another advantage of in situ conservation, which is most important to the evolutionary development of a species, is that it is much easier, more secure and financially more efficient to conserve a viable population of a species in its natural habitat than in an ex situ situation. It is often both the species and their habitat that are conserved. There is less competition for food, water and space among the organisms. 806 8067 22 The flora and fauna live in natural habitats without human interference. In-situ conservation is on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species. national parks, nature reserves. 3. In-situ conservation provides the required green cover and its associated benefits to our environment. They do not require the importation of expensive materials, skills or equipment. One significant advantage of ex situ conservation is that the genetic material is always available to the breeder for evaluation.
