Current efforts will not save the world's most endangered cat

Posted: 21 Jul 2013 01:17 PM PDT

Almost 100 million euros has been spent so far on conservation efforts for the last 250 remaining Iberian lynxes in the wild. But the charismatic species is likely to go extinct within 50 years because the current management plans do not account for the effects of climate change. If they did, the population might increase instead concludes a new international study. The study highlights the importance of integrating climate models in management plans for biodiversity.

Common stem cell in heart and lung development explains adaption for life on land

Posted: 21 Jul 2013 01:17 PM PDT

Biologists have known that the co-development of the cardiovascular and pulmonary systems is a recent evolutionary adaption to life outside of water. Researchers show that the pulmonary vasculature develops even in the absence of the lung. Mice in which lung development is inhibited still have pulmonary blood vessels, which revealed to the researchers that cardiac progenitors, or stem cells, are essential for cardiopulmonary co-development.
