About 10% of the species of the Earth can be found in Colombia, including over 1,900 species of bird, more than in Europe and North America combined, Colombia has 10% of the world's mammals species, 14% of the amphibian species and 18% of the bird species of the world. What Is Biodiversity? - Definition, Types And Importance, - BYJU'S World Health Organization(WHO) and Secretariat of the Convention on Biological Diversity (2015). India passed the Biological Diversity Act in 2002 for the conservation of biological diversity in India. ", Provisioning services which involve the production of renewable resources (e.g. Sovereignty principles can rely upon what is better known as Access and Benefit Sharing Agreements (ABAs). What is biodiversity | Environment, land and water - Queensland Government Barriers such as large rivers, seas, oceans, mountains and deserts encourage diversity by enabling independent evolution on either side of the barrier, via the process of allopatric speciation. [82] Indonesia's 17,000 islands cover 735,355 square miles (1,904,560km2) and contain 10% of the world's flowering plants, 12% of mammals and 17% of reptiles, amphibians and birdsalong with nearly 240million people. [126] Earth's surviving biodiversity provides resources for increasing the range of food and other products suitable for human use, although the present extinction rate shrinks that potential. Rapid environmental changes typically cause mass extinctions. Patterns of infectious diseases are sensitive to these disturbances. The killing, hunting or capturing of any species is prohibited except by or under the control of the highest authority in the department which is responsible for the management of the sanctuary. pete15 pete15 01/22/2016 Biology High School answered What does biodiversity refer to in an ecosystem See answers Advertisement Advertisement Cgale292 Cgale292 I'm pretty sure it would be refer to the variety of plants and animals It can define protection for threatened ecosystems, but also some rights and duties (for example. All rights reserved. Philosophically it could be argued that biodiversity has intrinsic aesthetic and spiritual value to mankind in and of itself. Major processes affecting infectious disease reservoirs and transmission include, deforestation; of natural pest enemies decreases herbivorous pest populations (Data from two separate reviews; Synthesis of 266 experimental and observational studies; of plants decreases disease prevalence on plants (Synthesis of 107 experimental studies), of plants increases soil organic matter (Synthesis of 85 experimental studies). Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval.

Biodiversity is the total variation between all living things and can be measured to help identify species that need to be supported. [1] Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Biologists most often define biodiversity as the "totality of genes, species and ecosystems of a region". [43][44][45] As of 2012, some studies suggest that 25% of all mammal species could be extinct in 20 years. It represents the wealth of biological resources available to us. The exotic organisms may be predators, parasites, or may outcompete indigenous species for nutrients, water and light. biodiversity loss, also called loss of biodiversity, a decrease in biodiversity within a species, an ecosystem, a given geographic area, or Earth as a whole. Hyperbolic model implies a second-order positive feedback. The control of damaging associated biodiversity is one of the great agricultural challenges that farmers face. Biodiversity - Stanford Encyclopedia of Philosophy [94] The hyperbolic pattern of the world population growth arises from a second-order positive feedback between the population size and the rate of technological growth. [221][222][223][224][225], Genetic erosion and genetic pollution have the potential to destroy unique genotypes, threatening future access to food security. Often hybridized breeds originated in developed countries and were further hybridized with local varieties in the developing world to create high yield strains resistant to local climate and diseases. Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. [41] This figure indicates unsustainable ecological practices, because few species emerge each year. [25] Other estimates include: Since the rate of extinction has increased, many extant species may become extinct before they are described. Local governments and industry have been pushing hybridization. If we lose the insects then everything is going to collapse. The biodiversity strategy is an essential part of the climate change mitigation strategy of the European Union. People depend on biodiversity in their daily lives, in ways that are not always apparent or appreciated. Why do we need biodiversity? A biodiversity hotspot is a region with a high level of endemic species that have experienced great habitat loss. What does biodiversity mean? The next 400million years included repeated, massive biodiversity losses classified as mass extinction events. Two aspects of organisms in a given environment: 1) The number of species (species richness) 2) The number of organisms within each specise What does the term biodiversity refer to? It is the most complex and important feature of our planet. For Australia to contribute to this target, it could mean scrutinising subsidies to agriculture, mining or forestry to consider and quantify their impacts on biodiversity. If a crop fails in a monoculture, we rely on agricultural diversity to replant the land with something new. [118] Biodiversity also affords many non-material benefits including spiritual and aesthetic values, knowledge systems and education.[118]. : zebra mussels and the emerald ash borer in the Great Lakes region and the lion fish along the North American Atlantic coast). It's all about the sustaining the natural area made up of community of plants, animals, and other living things that is begin reduced at a steady rate as we plan human . At present, several countries have already imported so many exotic species, particularly agricultural and ornamental plants, that their indigenous fauna/flora may be outnumbered. Diane Courtin on Twitter: "RT @timutteridge: What does the decline of National Geographic Headquarters 1145 17th Street NW Washington, DC 20036. crops, covers, symbionts, and livestock, among others), which can be contrasted with the associated diversity that arrives among the crops, uninvited (e.g. Some evidence suggests that invasive species are competitive in their new habitats because they are subject to less pathogen disturbance. [131], The growing demand and lack of drinkable water on the planet presents an additional challenge to the future of human health. What does biodiversity mean? - MathsGee Questions & Instant Answers [166][167], Rates of decline in biodiversity in the current sixth mass extinction match or exceed rates of loss in the five previous mass extinction events in the fossil record. Despite some limitations of the dataset-level analysis, it's clear that nearly half of all occurrence records shared through the GBIF network come from datasets with significant volunteer contributions. [190], Global warming is a major threat to global biodiversity. This hypothesis considers temperature, moisture, and net primary production (NPP) as the main variables of an ecosystem niche and as the axis of the ecological hypervolume. About 60 percent of all vascular plants are found in tropical forests. Human activities therefore allow species to migrate to new areas (and thus become invasive) occurred on time scales much shorter than historically have been required for a species to extend its range. Such disturbances reduce the abundance of some organisms, cause population growth in others, modify the interactions among organisms, and : landscape aesthetics, cultural heritage, outdoor recreation and spiritual significance). Gilbert White succinctly observed of his Selborne, Hampshire "all nature is so full, that that district produces the most variety which is the most examined. [124], Although about 80 percent of humans' food supply comes from just 20 kinds of plants,[125] humans use at least 40,000 species. [1] Several ecological factors may contribute to the gradient, but the ultimate factor behind many of them is the greater mean temperature at the equator compared to that of the poles. Biodiversity supports everything in nature that we need to survive: food, clean water, medicine, and shelter.
