Mongolian rangelands and climate change, fire-prone landscapes, and invasive Spartina grasses in San Francisco Bay are among topics How do humans and their environment interact, and how can we develop an understanding of these processes to adapt to a planet undergoing far-reaching climate and other environmental changes? To answer these and related questions, the National Science Foundation (NSF) has awarded 14 grants to scientists, engineers and educators across the country to study coupled...

Policy forum article in today's Science pleads for biodiversity scientists, pleads for biodiversity In a Policy Forum article in today's issue of Science, a group of leading biodiversity scientists, including NJIT's Daniel Bunker, have argued that targets to be met by 2020 under the Convention on Biological Diversity (CBD) must consider the real value of biodiversity if they are to be attained. "Ecosystem Services for 2020" outlines how biodiversity can be valued by considering the ecosystem...

Scientists will investigate forest change, marine viruses, honey bees, stream biodiversity, evolutionary history Despite centuries of discovery, most of our planet's biodiversity remains unknown. The scale of that unrecognized biodiversity is a vital question, scientists believe, given its rapid and permanent loss around the globe. To respond to the need for more knowledge and a better understanding of Earth's biodiversity, the National Science Foundation (NSF) has awarded 14 grants in its...

Human well-being is improving even as ecosystem services decline: Why? Global degradation of ecosystems is widely believed to threaten human welfare, yet accepted measures of well-being show that it is on average improving globally, both in poor countries and rich ones. A team of authors writing in the September issue of BioScience dissects explanations for this "environmentalist's paradox." Noting that understanding the paradox is "critical to guiding future management of ecosystem...

By 2100 only 18% to 45% of the plants and animals making up ecosystems in global, humid tropical forests may remain as we know them today, according to a new study led by Greg Asner at the Carnegie Institution's Department of Global Ecology. The research combined new deforestation and selective logging data with climate-change projections. It is the first study to consider these combined effects for all humid tropical forest ecosystems and can help conservationists pinpoint where their...

Redwood forest ecosystem of northern California depends on fog to stay hydrated during rainless summers As the mercury rises outdoors, it's a fitting time to consider the effects of summertime droughts and global warming on ecosystems. Complex interactions among temperature, water cycling, and plant communities create a tangled web of questions that need to be answered as we face a rapidly changing climate. Drs. Emily Limm and Todd Dawson (University of California, Berkeley) recently tackled...

STONY BROOK, N.Y., July 9 /PRNewswire-USNewswire/ -- A compendium on trophic cascades and how they operate in the world's major ecosystems has been published for the first time. The term "trophic cascades" refers to the follow-on effects of top predator removal from an ecosystem, and, until now, there has not been a comprehensive synthesis of this phenomenon. Evidence accumulated in this volume indicates that trophic cascades operate in nearly all ecosystems around the world, both at sea...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
