 | Vietnam’s only living animal deity could be in mortal danger. Already bearing multiple scars caused by pollution and illegal fishing at Hanoi’s Hoan Kiem Lake, the giant soft-shell turtle has sustained fresh injuries to its neck and carapace, said Ha Dinh Duc, a Vietnamese scientist who has been studying the giant species and kept a close watch on its conditions since 1991. |
The La Selle grass frog was the original target of Moore’s expedition but the species, last seen in 1985, eluded scientists and remains lost—if it survives at all.
But Moore said it appears that if Haitians can protect the pockets of forest that remain, many of the species that live there have more than a fighting chance of survival because they were found in such relatively good numbers.
“It really shows that even in a small patch of suitable habitat you can have an abundance of frogs despite what’s going on around it,” he said. “That was very encouraging to me. It was pretty exhilarating and it really exceeded any of my expectations of what we would find.” Ir a la galería.
Olfaction is a common sensory mode of communication in much of the Vertebrata, although its use by adult frogs remains poorly studied. Being part of an open signalling system, odour cues can be exploited by ‘eavesdropping’ predators that hunt by smell, making association with odour a high-risk behaviour for prey. Here, we show that adult great barred frogs (Mixophes fasciolatus) are highly attracted to odour cues of conspecifics and those of sympatric striped marsh frogs (Limnodynastes peronii). Leer más.
