| Social media data could contribute to conservation science Posted: 15 Sep 2015 07:50 AM PDT Planning conservation actions requires up-to-date information on biodiversity, but also on human pressures. Scientists who collect data are few and far between on a global scale, but nature enthusiasts are everywhere. Spending time on social media might be helpful for biodiversity conservation, argue researchers. |
| World loses trillions of dollars worth of nature's benefits each year due to land degradation Posted: 15 Sep 2015 06:04 AM PDT Experts estimate the value of ecosystem services worldwide forfeited due to land degradation at US $6.3-10.6 trillion annually, or the equivalent of 10-17 percent of global GDP, a new report suggests. An estimated 50 million people may be forced to seek new homes and livelihoods within 10 years. That many migrants assembled would constitute the world's 28th largest country by population. |
| Posted: 14 Sep 2015 06:56 PM PDT In ongoing research to record the interaction of environment and evolution, a team of researchers has found new information illustrating the evolution of a population of guppies. Working in a river in Trinidad, the researchers determined which male guppies would contribute more offspring to the population as well as which would live longer and which would have a shorter lifespan. |
| Researchers find major gaps in understanding risks, benefits of eating fish Posted: 14 Sep 2015 09:47 AM PDT Fish tissue is rarely measured for concentrations of both harmful contaminants and healthful nutrients across a range of species and geographic regions, says a research team who reviewed the risks and benefits of eating seafood. |
| Protected areas save mangroves, reduce carbon emissions Posted: 14 Sep 2015 09:47 AM PDT Protected areas not only keep significant swaths of Indonesia's shrinking mangrove habitats intact, but also prevent emissions of carbon dioxide that would have been released had these mangroves been cleared, according to a study. |
