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.

The effects can vary depending on both the size to which the population is reduced and the duration of the bottleneck (i.e., the number of generations).

Biodiversity Factsheet | Center for Sustainable Systems

Biodiversity, or biological diversity, is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems, and the ecological complexes of which they are part. 1 Biodiversity shapes the ecosystem services that contribute to human well-being—material welfare, security, social relations, and health. 2 Biodiversity is considered on three ...

Biodiversity - Wikipedia

History of terminology. 1916 – The term biological diversity was used first by J. Arthur Harris in "The Variable Desert," Scientific American: "The bare statement that the region contains a flora rich in genera and species and of diverse geographic origin or affinity is entirely inadequate as a description of its real biological diversity."

Hieracium hethlandiae is a species of hawkweed native to the Shetland Islands. Although the species was officially considered extinct since its habitat was destroyed 40 years ago, it survived in plant collections and was reintroduced to its rocky home in 2015.

Conserving Biodiversity

Genetic Diversity. Genetic diversity is a part of biodiversity in that it leads to speciation. Gene variation, or polymorphism, allows populations to adapt to their environment, based on natural selection. The trick is that if a beneficial mutation occurs in an individual's genes, then it will be more adapted to its environment and so it will ...

Telomere and Telomerase Biology - ScienceDirect

Telomerase is a high-molecular weight RNP complex that consists of two major components: TER and a TERT (Fig. 1.2A).TER is a noncoding RNA that is essential for telomere synthesis; it serves as a template to elongate the 3′ overhang of the telomeric G-rich strand.5, 19 TERT is a protein component that acts as a specialized reverse transcriptase and contains conserved catalytic domains.

Move it or lose it: Exploiting genetic diversity to fight ...

Species are becoming restricted to smaller and smaller habitats due to human pressures, climate change and the onslaught of invasive species. Once fragmented, or reduced in size for other reasons, populations become prone to the loss of genetic diversity through a process called genetic drift.

Purdue University Captive Breeding

Maintaining genetic diversity is important, as diversity is lost at every generation due to random genetic drift as well as inbreeding. Additionally, captive populations can become a little bit better adapted to the captive environment at every generation due to genetic and behavioral changes. While this may not always be detrimental, changes ...

Introduction to Biodiversity - Center for Biodiversity Outcomes

Biodiversity includes the diversity within species and between different species within terrestrial, freshwater and marine ecosystems. Ecosystems need a balanced and diverse number of species to thrive. When people think of conserving biodiversity, they often think of efforts to save animals such as the polar bear or the tiger.

What is biodiversity, and why is it important? - Landscape News

Likewise, genetic diversity protects a species from being wiped out by an external shock like a natural disaster or disease outbreak. At the largest scale is the concept of ecosystem diversity , which measures how many different ecosystems exist within a geographical area or wider landscape.

Conservation of Megadiverse Countries - Iberdrola

The mega-diverse countries are those that house the largest indices of biodiversity, including a large number of endemic species. This concept was first proposed in 1988 by Russell Mittermeier and is now used to raise awareness to the protection of natural biodiversity, and particularly in the countries where this is more abundant and threatened.
