Pelagic sea snakes dehydrate at sea.
Secondarily marine vertebrates are thought to live independently of fresh water. Here, we demonstrate a paradigm shift for the widely distributed pelagic sea snake, Hydrophis (Pelamis) platurus, which dehydrates at sea and spends a significant part of its life in a dehydrated state corresponding to seasonal drought. Snakes that are captured following prolonged periods without rainfall have lowe...

activity during sleep. Interestingly, the pattern of firing observed is specific to the song heard, suggesting that the neuronal activity carries with it information about the song itself. However, the quality of the juvenile’s song actually worsens after sleep, and improves only with practice the next day. Importantly, this effect is dependent upon sleep per se, as it is observed following day...

متن کاملPolarized Sea Measurements at Jparc
Helicity distributions of valence quarks have been investigated in many experiments and are now well known. On the other hand, the distributions of the polarized sea are poorly known. In particular, concerning ∆ū(x), fits assuming a totally flavour symmetric sea suggest a sign opposite respect to fits based on a flavour broken sea . The situation is even more confused concerning the transversit...
متن کاملHow Tropicbirds Behave at Sea
28 fledged per nest in the native habitat, but only 1.0 per nest in the wheatgrass, Lloyd and Martin reported in 2005 (Condor 107:363–374). These significantly different success rates resulted primarily from greater nest predation in the wheatgrass. The odds of a nest surviving a given day were 17 percent higher in the native-prairie patches than in the wheatgrass plots. Nestlings in the native...
