A global synthesis reveals biodiversity loss as a major driver of ecosystem change
Opinion: Biodiversity Impacts Humanity
Increasing evidence suggests that loss of Earth’s biological diversity will compromise our planet’s ability to provide the goods and services societies need to prosper.
A Biodiversity Map, Version 2.0
University of Copenhagen Researchers have produced a new biodiversity map divided into 11 large biogeographic realms. Tigers and pandas live in Asia, kangaroos and koalas in Australia and polar bears and snowy owls in the Arctic. The world can be divided into regions based upon the unique types of animals that live there.

Scientists in the journal Nature have released yet another study full of dire predictions. This study analyzed ecological data from protected reserves in 36 tropical countries,the British Independent reported on July 27, and found that half of the reserves are showing the effects of what is happening outside their borders. Moreover, one of the researchers told Bloomberg , the resulting changes are even more marked than those resulting from climate change.
The world's biodiversity is down 30 percent since the 1970s, according to a new report, with tropical species taking the biggest hit.
Report: Global Biodiversity Down 30 Percent in 40 Years
The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only species we consider rare, threatened, or endangered, but every living thing—even organisms we still know little about, such as microbes, fungi, and invertegrates.

They have entranced generations with the beauty of their songs and glimpses of their plumage.Impacts of Biodiversity Loss Escalate Through Time as Redundancy Fades
Abstract Plant diversity generally promotes biomass production, but how the shape of the response curve changes with time remains unclear. This is a critical knowledge gap because the shape of this relationship indicates the extent to which loss of the first few species will influence biomass production.UN

Brief overview Dryland species must adapt to an environment known for its variation in climate, both in terms of temperature and water availability. Some areas have been identified as especially important to the survival of these uniquely adapted plants and animals: Centers of Plant Diversity; Endemic Bird Areas; Protected Areas; and Global 200 Ecoregions.

Protecting biodiversity reduces poverty in developing nations
Among conservationists, policy-makers, and the public, there is great debate about whether the establishment of national parks and reserves in developing nations causes poverty or helps to alleviate it. While opponents claim that protected areas limit agricultural development and the harvesting of natural resources, supporters contend that protected areas generate tourism income and improve infrastructure in the surrounding areas.Amazon rainforest mapped in unprecedented detail | Environment
