Why are ecosystems so delicate?

High rates of species turnover or population fluctuations characterize fragile ecosystems, and vice versa. The diversity of ecological processes related to these changes makes ecosystem fragility a central evaluation criterion in conservation management.

What are 3 reasons ecosystems are fragile?

Factors which make an ecosystem fragile:

  • Climate Change: A global phenomenon, it results in changes in temperature and rainfall patterns. …
  • Natural disasters like earthquake. …
  • Human Activities: …
  • Introduction of exotic species which compete with native species and can affect the ecosystem.

Why do fragile environments need protecting?

Cold environments provide one of the last wilderness areas on Earth and have fragile ecosystems. Economic development puts these ecosystems at serious risk of damage and therefore these areas need to be protected.

What is the impact of ecological fragility?

The development of social economic and the security of the ecological environment are closely linked and interact with each other. The fragility of the environment directly affects the stability of the regional ecosystem and the sustainable development of the ecological environment.

Why are some ecosystems delicate and some resilient?

He stated that ecosystem stability increased as the number of interactions (complexity) between the different species within the ecosystem also increased. … This elasticity means that ecosystem properties, such as changes in nutrient flow or the number of species, are more resilient due to changes in species composition.

What do you mean by mountain ecosystem?

source:SlideShare fig: Mountain ecosystem. It is a high altitude terrestrial ecosystem in which the land is vertically distributed.

Why are earth’s mountains under threat?

“Mountain forests are being affected by many global challenges, such as climate change, water scarcity, loss of biodiversity and desertification, but they also offer significant opportunities for solutions. Sustainable development of mountain forests requires and deserves a prominent place on the international agenda.”

What is a delicate ecosystem?

Delicate is describing the ecosystems, so lets use both of the descriptions, Delicate ecosystems –> Must have a perfect balance in order to sustain itself. If one factor is wrong then the ecosystem might be damaged – broken easily. Delicate ecosystems –> Was formed in a very careful/detailed/intricate way.

Why are ecotones fragile?

… One is decreased the other is unaffected 0 -Ecotones are stochastic, unstable ecological zones [13] characterised by instability due to the sensitivity to environmental changes [14] and the reaction between the adjacent zones [6].
