The Areas guide provides short articles about selected areas of importance for biodiversity conservation. It explains in detail a number of recognised systems to protect, prioritise and identify areas of biodiversity importance that fall into two main categories: protected areas and biodiversity designations. Area designations categorised as protected areas are those under protected area frameworks, that have legal or other effective protection at the national level. Some have additional recognition through regional or international conventions and agreements. Area designations categorised as biodiversity designations are developed by governments, academics and NGOs in order to identify areas of biodiversity importance or areas where biodiversity is threatened, as a means to focus attention and resources on their conservation.

Areas of Biodiversity Importance

The core threat to biodiversity on the planet, and therefore a threat to human welfare, is the combination of human population growth and resource exploitation. The human population requires resources to survive and grow, and those resources are being removed unsustainably from the environment. The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species. The first two of these are a direct result of human population growth and resource use. The third results from increased mobility and trade.

This IBAT Country Profile delivers nationally relevant data that are disaggregated from global datasets, to support conservation planning and reporting. More information on these datasets can be found below. IBAT Country Profiles are designed to build understanding of information about Protected Areas, important sites and species present, to aid national decision-making.

The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists.

What is Biodiversity?

In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change. The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach to preserving biodiversity. Almost all cultures have their roots in our biological diversity in some way or form. Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. And so, while we dominate this planet, we still need to preserve the diversity in wildlife.

Biodiversity is the biological variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic , species , and ecosystem level. Rapid environmental changes typically cause mass extinctions. The age of the Earth is about 4. There are microbial mat fossils found in 3.

Вверху мирно раскачивалась курильница. Халохот, расталкивая людей, двигался по центральному проходу, ища глазами намеченную жертву. Он где-то. Халохот повернулся к алтарю. В тридцати метрах впереди продолжалось святое причастие. Падре Херрера, главный носитель чаши, с любопытством посмотрел на одну из скамей в центре, где начался непонятный переполох, но вообще-то это его мало занимало.

The loss of biodiversity reduces ecosystem resilience and increases vulnerability to threats including negative impacts of climate change (well established).
