Birds and beans: Study shows best coffee for bird diversity

Fri, 16 Feb 18 00:12:20 -0800

It's an age-old debate for coffee lovers. Which is better: Arabica beans with their sweeter, softer taste, or the bold, deep flavor of Robusta beans? A new study by WCS, Princeton University, and the University of Wisconsin-Madison appearing in the journal Scientific Reports has taken the question to unlikely coffee aficionados: birds.

For tropical forest birds, old neighborhoods matter

Thu, 15 Feb 18 00:00:20 -0800

Old, complex tropical forests support a wider diversity of birds than second-growth forests and have irreplaceable value for conservation, according to an Oregon State University-led exhaustive analysis of bird diversity in the mountains of southern Costa Rica.

The more kinds of bees, the better for humans, Rutgers-led study finds

Thu, 15 Feb 18 00:07:30 -0800

The bigger the area to pollinate, the more species of wild bees you need to pollinate it.

Carefully managed fire can promote rare savanna species

Wed, 14 Feb 18 00:13:50 -0800

In the first continent-wide study of the effects of fire on bird and mammal diversity in the African savanna environment, researchers have found that increasing 'pyrodiversity' boosts the variety of species of mammals by around 20 percent and of birds by 30 percent in savannas with high rainfall.

Deforestation in the tropics

Wed, 14 Feb 18 00:06:40 -0800

Scientists at the UFZ have adapted a method from physics to mathematically describe the fragmentation of tropical forests. In the scientific journal Nature, they explain how this allows to model and understand the fragmentation of forests on a global scale. They found that forest fragmentation in all three continents is close to a critical point beyond which fragment number will strongly increase. This will have severe consequences for biodiversity and carbon storage.

UA scientist studies effects of wildfire management on bird populations

Wed, 14 Feb 18 00:11:00 -0800

On the tail of California's most destructive and expensive year of firefighting ever, it might seem obvious that vegetation removal would reduce the risk of such a year happening again. But scientists from the University of Arizona and the University of California, Berkeley, are showing that in chaparral, California's iconic shrubland ecosystem, management can devastate wild bird populations and that fire-risk reduction is only temporary.

FSU researchers: Savanna fires pump Central African forests full of nitrogen

Thu, 08 Feb 18 00:10:40 -0800

Florida State University researchers are part of a global team of scientists revealing the unexpected role that large-scale fires and high nitrogen deposition play in the ecology and biogeochemistry of these lush Central African forests.

Iberian Peninsula rodents migrated due to climate change twelve million years ago

Tue, 06 Feb 18 00:15:20 -0800

Changes in Southwestern Europe's climate which happened between 12 and 5 million years ago had a drastic impact over the rodent communities. These profound changes in environmental conditions led to a separation between species adapted to arid environments which migrated to interior regions of the Iberian Peninsula and species adapted to humid environments thriving where Catalonia and France are today, according to a study led by a team from Universidad Complutense de Madrid, Madrid, Spain

Conservation stories from the front lines

Mon, 05 Feb 18 00:02:30 -0800

A new collection, 'Conservation Stories from the Front Lines,' publishing between Feb. 5-7 in the open access journal PLOS Biology, captures the long-neglected human side of science by entering the tragedy, comedy, and (mis)adventures that shape research into the scientific record as peer-reviewed scientific stories. The stories come from scientists working to manage and preserve biodiversity, and offer a new way to engage diverse audiences in today's pressing scientific issues.

Mapping the first family tree for tropical forests

Mon, 05 Feb 18 00:03:30 -0800

More than 100 researchers have collaborated to classify the world's tropical forests according to their evolutionary history, a process that will help researchers predict the resilience or susceptibility of different forests to global environmental changes.

New parasitoid wasp likely uses unique saw-like spines to break out of its host body

Wed, 31 Jan 18 00:08:40 -0800

A newly discovered parasitoid wasp species from Costa Rica might be only slightly larger than a sesame seed, yet it has quite vicious ways when it comes to its life as an insect developing inside the body of another. Most likely, it uses its unique saw-like row of spines on its back to cut its way out of its host. The study is published in the open access Biodiversity Data Journal.

A glimpse in the flora of Southeast Asia puts a spotlight on its conservation

Wed, 31 Jan 18 00:13:40 -0800

Covering only 3 percent of Earth's total land area, four overlapping biodiversity hotspots in South East China -- Indo-Burma, Philippines, Sundaland and Wallacea -- are estimated to be the home of the astonishing 20 to 25 percent of higher plant species in the area. While offering an insight into this extraordinary flora, a new special issue published in the open access journal PhytoKeys, contributes to the total count with seventeen new species from the region.

Evolution of China's flowering plants shows East-West divide between old, new lineages

Wed, 31 Jan 18 00:00:00 -0800

An international team of scientists has mapped the evolutionary relationships between China's 30,000 flowering plant species, uncovering a distinct regional pattern in biodiversity. Eastern China is a floral 'museum' with a rich array of ancient lineages and distant relatives while the western provinces are an evolutionary 'cradle' for newer and more closely related species.

Warming climate shrinks British Columbia beetles

Tue, 30 Jan 18 00:13:10 -0800

Some of B.C.'s beetles are shrinking as their habitats get warmer, according to new UBC research. The study provides evidence that climate change is affecting the size of organisms.

Viruses prefer cultivated areas to natural areas

Tue, 30 Jan 18 00:02:10 -0800

Cultivated areas are more affected by viral epidemics than non-cultivated areas. This is the finding of an international study carried out as part of a France-South Africa collaboration in floristic areas from the Western Cape and Camargue regions. These results were published in January 2018 in The ISME Journal, a journal of microbial ecology.
