As part of her PhD research Dr Melanie Seiler studied the Sahamalaza sportive lemur in its natural habitat and found that it pays close attention to the vocalisations of other species in their habitatto detect and avoid predation by both terrestrial and airborne predators.Interspecific Semantic Alarm Call Recognition in the Solitary Sahamalaza Sportive Lemur, Lepilemur sahamalazensis Seiler, M., Schwitzer, C., Gamba, M. & Holderied, M.

Masters by Research student Samuel Penny (Co-supervised by Dr C. Schwitzer at the BCSF) returned from his field work in Madagascar with a specimen of an unkown tree frog. This has turned out to be a new species. Sam has named it Boophis ankarafensis and he is currently preparing the species description for publication.
In a study published in PLOS ONE, Dr Marc Holderied and colleagues from Bristol's School of Biological Sciences and Ben-Gurion University of the Negev, Israel demonstrate the importance of dense acacia tree habitats for protected bats and their arthropod prey (for example, insects, spiders and scorpions) in comparison to other natural and artificial habitats.

Like a stealth fighter plane, the barbastelle bat uses a sneaky hunting strategy to catch its prey. A team of researchers from the University of Bristol combined three cutting-edge techniques to uncover the secret of this rare bat’s success: whispering.

While it is well known that the bright colours of flowers serve to attract visually-guided pollinators such as bees and birds, little research has been done to see whether plants which rely on echolocating bats for pollination and seed dispersal have evolved analogous echo-acoustic signals. The researchers discovered that a rainforest vine, pollinated by bats, has evolved dish-shaped leaves with such conspicuous echoes that nectar-feeding bats can find its flowers twice as fast by echolocation.
