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.

 | Of all the startling images to have come out from the Queensland floods, this has to be the most unusual — a green frog hitching a ride on the back of a brown snake. Computer technician Armin Gerlach was visiting friends in the flood-hit town of Dalby, located in the state’s south-east, last week when he spotted the unlikely pair. |
 | Those with an ear to the ground might well have heard already about Gwawinapterus a new istiodacylid pterosaur from Canada. This is quite a find as it represents the first istiodactylid from outside Eurasia and is by far the most recent extending both the geographic and temporal range of the group. Describer Victoria Arbour, (who also writes the rather entertaining Pseudplocephalus blog about her dinosaur travels) takes us through the history of the find and the difficult identification of the jaws. |
