New species take longer to arise in the Amazon
Amazonia is home to the greatest number of species on earth, many now threatened, but a new study hammers home Amazonia's importance, showing that it is not only a place with many species, but one where it has taken an exceptionally long time for new species to form.
Read moreSurvey completeness of a global citizen-science database of bird occurrence
There are many shortfalls in knowledge of the world's biodiversity, and one of the most basic is the lack of knowledge about where species occur geographically. This deficiency has broad ramifications for research and conservation. This study suggests the development of citizen science programs to collect data by volunteers has the potential to reduce this shortfall.
Read moreAre humans changing animal genetic diversity worldwide?
Human population density and land use is causing changes in animal genetic diversity, according to new research. The research show that environmental changes caused by humans are leading to changes in genetic variation in thousands of species of birds, fish, insects, and mammals. The evidence for human impacts was most clear for insects and fish species.

A new study demonstrated the potential of the TROPOspheric Monitoring Instrument on board the Copernicus Sentinel-5 Precursor satellite to measure and track chlorophyll fluorescence and photosynthesis of tropical forests in the Amazon.
Read moreNew study underpins the idea of a sudden impact killing off dinosaurs and much of the other life
Fossil remains of tiny calcareous algae not only provide information about the end of the dinosaurs, but also show how the oceans recovered after the fatal asteroid impact.

Fish may be more tolerant than previously thought to periods of low oxygen in the oceans, new research shows.
Read moreAmazon's white bellbirds set new record for loudest bird call
Biologists report that they have recorded the loudest bird calls ever documented, made by dove-sized male white bellbirds as part of their mating rituals in the mountains of the northern Amazon.
Read moreThe secret of classic Belgian beers? Medieval super yeasts!
An international team of scientists has discovered that some of the most renowned classic Belgian beers, including Gueuze and Trappist ales, are fermented with a rare and unusual form of hybrid yeasts. These yeasts combine DNA of the traditional ale yeast, Saccharomyces cerevisiae, with that of more stress-resistant feral yeasts such as Saccharomyces kudriavzevii.
Read moreGenBank can be trusted, study shows
Scientists working to identify coral reef organisms analyzed more than 4.7 million animal DNA sequences from GenBank, the most commonly used tool used to identify environmental DNA, and discovered that animal identification errors are surprisingly rare — but sometimes very funny.
