Hairs, Feathers and Scales Have a Lot in Common!

dragon_barbu.jpg

The potential evolutionary link between hairs in mammals, feathers in birds and scales in reptiles has been debated for decades. Today, researchers of the University of Geneva (UNIGE) and the SIB Swiss Institute of Bioinformatics, Switzerland, demonstrate that all these skin appendages are homologous: they share a common ancestry. On the basis of new analyses of embryonic development, the Swiss biologists evidenced molecular and micro-anatomical signatures that are identical between hairs, feathers and scales at their early developmental stages. These new observations, published today in Science Advances, indicate that the three structures evolved from their common reptilian ancestor.

University of Utah biologists working in Turkey discovered two surprising facts about a group of 16 brown bears: First, six of the bears seasonally migrated between feeding and breeding sites, the first known brown bears to do so. Second, and more sobering, the other 10 bears stayed in one spot all year long: the city dump.

Lizard Tail Adaptations May Reflect Predators' Color Vision Capabilities

118225_web.jpg

Juveniles of numerous lizard species have a vividly blue-colored tail that likely serves to deflect predator attacks toward the detachable tail rather than the lizard's body. Now researchers have found that certain differences in blue and UV light reflectance in lizard tails are likely adaptations to predators with different color vision capabilities.

BRI Reports Status of Common Loon Translocation Study

Biodiversity Research Institute (BRI) presents a mid-point progress report of the largest Common Loon conservation study ever conducted. Funded in 2013 by the Ricketts Conservation Foundation, Restore the Call is a five-year science-based initiative to strengthen and restore loon populations within their existing and former range. Research efforts are focusing in three key U.S. breeding population centers from the western mountains to the Atlantic seaboard.

How Chameleons Capture Their Prey

Despite their nonchalant appearance, chameleons are formidable predators, capturing their prey by whipping out their tongues with incredible precision. They can even capture preys weighing up to 30% of their own weight. In collaboration with the Muséum national d'Histoire naturelle de Paris, researchers from the Université de Mons (UMONS) and the Université libre de Bruxelles (ULB) have studied this amazing sticky weapon.
