Classic Model For Ecological Stability Revised

Predator-prey relationships stabilize diverse ecosystems, according to calculation A famous mathematical formula which shook the world of ecology 40 years ago has been revisited and refined by two University of Chicago researchers in the current issue of Nature. In 1972, physicist Robert May rankled ecologists by publishing a simple model describing the relationship between diversity and stability in a theoretical ecosystem. Though ecologists had long believed that richer, more diverse...

Study suggests that plant biodiversity buffers negative climate change effects and drylands desertification An international team of researchers including Dr. Bertrand Boeken of the Jacob Blaustein Institutes for Desert Research at Ben-Gurion University of the Negev suggest in a new study that plant biodiversity preservation is crucial to buffer negative effects of climate change and desertification in drylands. The study titled, "Plant species richness and ecosystem multi-functionality...

Diverse Ecosystems Are Crucial Climate Change Buffer

Preserving diverse plant life will help buffer the negative effects of climate change and desertification in drylands Preserving diverse plant life will be crucial to buffer the negative effects of climate change and desertification in the world's drylands, according to a new landmark study. The findings of the multi-author study, published January 12 in the journal Science, are based on samples of ecosystems in every continent except Antarctica. They confirm for the first time that...

High-priority sites for biodiversity conservation yield many of the world's ecosystem services, and ensuring that the stewards of such areas were paid by their beneficiaries could substantially alleviate poverty Land areas that are a priority for wildlife conservation provide relatively high levels of ecosystem services such as pollination, water purification, food production, and climate regulation, so safeguarding them is expected to benefit people. Assessing these benefits to...

Those making land use decisions to reduce the harmful effects of climate change have focused almost exclusively on greenhouse gases — analyzing, for example, how much carbon dioxide is released when a forest is cleared to grow crops. A new study in Nature Climate Change aims to present a more complete picture — to incorporate other characteristics of ecosystems that also influence climate. "We know that forests store a lot of carbon and clearing a forest releases carbon dioxide...

Image 1 - Climate Change Could Create Big Ecosystem Changes

By 2100, global climate change will modify plant communities covering almost half of Earth's land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type - such as forest, grassland or tundra - toward another, according to a new NASA and university computer modeling study. Researchers from NASA's Jet Propulsion Laboratory and the California Institute of Technology in Pasadena, Calif., investigated how Earth's plant life...

Growing acceptance for controversial strategies including 'conservation triage' The number of species being recognized as endangered is ever increasing and a new study, published in Conservation Biology, reveals the unanimity among conservation scientists of expectations of a major loss of biological diversity. The survey also shows a growing acceptance of controversial strategies such as triage, a decision to priorities resources and not to intervene to save some highly threatened...

The world's coastal marine ecosystems are being overlooked, both in terms of their ecological importance and their potential as a rallying point for conservation. Writing in Aquatic Conservation: Marine and Freshwater Ecosystems Project Seahorse Director Dr. Amanda Vincent argues that increased protections are needed for the first 10 metres of depth of the world's oceans, where the richest diversity of marine habitats and animal life can be found and where most ocean-related human activity...

Experts warn some payment mechanisms to support ecosystems services may be environmentally harmful, different measures needed Over the past 50 years, 60 percent of all ecosystem services have declined as a direct result of the conversion of land to the production of foods, fuels and fibers. "This should come as no surprise," say seven of the world's leading environmental scientists, who met to collectively to study the pitfalls of utilizing markets to induce people to take account of...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
