| Posted: 17 Sep 2015 09:52 AM PDT Altered or new environmental conditions, such as those brought about by climate change, impose challenges on living organisms. This can drive species to extinction if they fail to adapt or adjust their geographic distribution. Individual differences play a key role here, and it seems that less is not always more. A new study demonstrates that a higher degree of among individual variation is beneficial to populations and species.  |
| Omega-3s are vital for a healthy ocean Posted: 17 Sep 2015 08:01 AM PDT The importance of omega-3 fatty acids for the health of the ocean has been revealed by a new study. This research shows that 'ocean-fleas' play a vital role in maintaining a healthy ocean depend on omega-3's to survive. These 2 mm long creatures, called copepods, are distant relatives of crabs and lobsters and rank amongst the most abundant animals on our planet. They get omega-3's from eating microscopic plants in the sea that absorb carbon from the atmosphere. This carbon then gets transported into the deep sea by sinking copepod poo, stopping it returning to the atmosphere.  |
| Small rural owl fearlessly colonizes the city Posted: 17 Sep 2015 08:01 AM PDT Think of the city and images of traffic, pollution, noise and crowds spring to mind. The metropolis doesn't seem to be the most ideal habitat for any animals other than humans. However, Spanish and Argentinean scientists have demonstrated that some species, such as the burrowing owl, have spent decades closing in on the city from the country without suffering from stress.  |
| Ocean’s wildlife populations down by half Posted: 17 Sep 2015 06:50 AM PDT A new report reveals an alarming decline in marine biodiversity over the last few decades. According to the report, populations of marine vertebrates have declined by 49% between 1970 and 2012, with some fish species declining by almost 75%.  |
| Invasive brood parasites a threat to native bird species Posted: 16 Sep 2015 01:29 PM PDT North Americans might be seeing new species of birds in certain areas of the continent in the near future. According to research, Eurasian birds are beginning to develop a presence on our continent, which could end up having a negative effect on native species.  |
| Novel competitors affect species' responses to climate change Posted: 16 Sep 2015 01:21 PM PDT As the climate warms, many plants face an uphill struggle for survival. A new study indicates that this is particularly true wherever they face increased competition from plants that have migrated to their habitat due to climactic changes.  |
