Explorers find hundreds of undescribed corals, other species on familiar Australian reefs

Hundreds of new kinds of animal species surprised international researchers systematically exploring waters off two islands on the Great Barrier Reef and a reef off northwestern Australia -- waters long familiar to divers. The expeditions, affiliated with the global Census of Marine Life, help mark the International Year of the Reef and included the first systematic scientific inventory of spectacular soft corals, named octocorals for the eight tentacles that fringe each polyp 


Biodiversity convention is criticized as lightweight on science
Darkfrog submitted, created time 3 months 1 week (www.nature.com)
Swedish researchers have criticized the body that advises the Convention on Biological Diversity as light on science and overly dominated by politics, and they are not alone. According to Dr. M. Stocking of the United Kingdom, the people who end up in positions as advisors "tend to be government nominees … not scientists who are up to date with the literature 
Accelerated Human Population Growth at Protected Area Edges

Protected areas (PAs) have long been criticized as creations of and for an elite few, where associated costs, but few benefits, are borne by marginalized rural communities. Contrary to predictions of this argument, investigators found that average human population growth rates on the borders of 306 PAs in 45 countries in Africa and Latin America were nearly double average rural growth, suggesting that PAs attract rather than repel, human settlement

From this result of this study, we know that the latitudinal gradient in marine bacteria supports the hypothesis that the kinetics of metabolism, setting the pace for life, has strong influence on diversity. 


Global biodiversity slumps 27% in 35 years

From this study, the latest data on the global biodiversity of vertebrates shows that it has fallen by almost one-third in the last 35 years. But experts say it may still underestimate the effect humans have had on global species counts. 


The relationship between plant species diversity and its productivity

Plant species diversity has a high effect on productivity in natural settings. In this article, they found that aboveground net primary production increased with the number of plant species. They point out that the effect of biodiversity in natural ecosystems may be much larger than currently thought

Scientists have hit upon a way to spy on invasive wetland species without ever having to see them: They simply detect their DNA in the water. The technique works on bullfrogs, which are an invasive species outside of North America, and such DNA scans could eventually be used in rapid surveys of biodiversity. 


New Species of Infectious Disease

While investigating the tropical disease leptospirosis in the Peruvian Amazon, an infectious disease specialist from the University of California, San Diego School of Medicine has uncovered new, emerging bacteria that may be responsible for up to 40 percent of cases of the disease.

Plants grown as food crops on small farms show a surprising amount of biodiversity worldwide, an international team has found. The findings bode well for efforts to preserve diversity as a hedge against plant diseases, insect pests, and global climate change. 
Threat to Tropical Forest Biodiversity

Climate change may not be as serious a threat to tropical forest biodiversity as previously thought, according to a new study. The question of whether rising carbon dioxide levels act as a forest fertilizer remains unresolved, however. 
Researchers Map Corn Plant's Genome

Researchers have sequenced the gene map of corn, also known as maize, a key crop across much of the world and a source of food, oil and products ranging from shoe polish to ethanol. 


Abrupt climate change and collapse of deep-sea ecosystems

The article investigated the deep-sea fossil record of benthic ostracodes during periods of rapid climate and oceanographic change over the past 20,000 years in a core from intermediate depth in the northwestern Atlantic. Results show that deep-sea benthic community "collapses" occur with faunal turnover of up to 50% during major climatically driven oceanographic changes. 
DNA barcoding for botanical identities

Researchers have used a DNA sequence to distinguish between more than 1,600 botanical samples from two biodiversity hotspots, providing the largest test yet of "DNA barcoding" in plants. 


Exponential Decline of Deep-Sea Ecosystem Functioning Linked to Benthic Biodiversity Loss

Recent investigations suggest that biodiversity loss might impair the functioning and sustainability of ecosystems. They present a global-scale study based on 116 deep-sea sites that relates benthic biodiversity to several independent indicators of ecosystem functioning and efficiency.

As the bright green fuzz on streamside rocks or the living carpet on forest floors, mosses revel in their relative simplicity, lacking the roots, seeds, and flowers typical of most land plants. Yet the first analysis of a moss genome reveals that mosses are surprisingly complex, with 35,000 potential genes--10,000 more than the first land plant sequenced--and a host of unique adaptations not found in other green landlubbers. And because of where mosses fall on the plant family tree, those genes are revealing how plants made their way onto land.
