To date, attempts to repopulate restored and created habitat through natural immigration and active translocation of tadpoles and juveniles have been met with limited success for this species. We used L. aurea to determine if distribution could be manipulated via conspecific attraction using artificial communication cues. We placed speaker systems in uninhabited areas of five inhabited ponds across two locations and broadcast calls of L. aurea to see if we could manipulate distribution into previously unoccupied pond areas. Surveys undertaken before and after broadcast indicate that we successfully manipulated L. aurea distribution for adults increasing both occupancy and calling around the speaker locations. This occurred in four of five replicate ponds over three months of experimental treatment, but controls remained low in abundance. We suggest that manipulation of distribution via conspecific attraction mechanisms could be a useful conservation tool for endangered amphibian habitat restoration and creation programmes, resulting in increased occupancy and programme success.]]> Sat 24 Mar 2018 07:40:12 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:4725 200 m) to ephemeral waterbodies from permanent waterbodies after prolonged heavy rain. Of the total number of male and female movements recorded, 44 (39%) and two (14%) were to or from ephemeral waterbodies, respectively. Our results demonstrated high site fidelity of L. aurea to individual waterbodies and groups of neighboring waterbodies, especially permanent ones. Our results showed that L. aurea tended to breed in more permanent waterbodies but reproduced opportunistically in ephemeral waterbodies where recruitment was less successful. Habitat restoration projects for L. aurea should construct permanent and ephemeral waterbodies and provide adequate buffer zones that protect the terrestrial habitat.]]> Sat 24 Mar 2018 07:21:50 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:23914 Litoria aurea) have suffered considerable shrinking of their original distribution in south-eastern Australia since the 1970s. Currently, with only about 40 populations remaining, the species is considered nationally threatened. In natural conditions, these frogs are aggregated in the landscape and do not seem to occupy all suitable ponds within the occurrence area. To date, studies focusing on the frogs' habitat have failed in finding a general habitat feature that explains current or past occupancy. This led us to the hypothesis that social cues may play a key role in habitat selection in this species. Using two choice experiments, we tested the preference of juvenile green and golden bell frogs for habitats containing cues of conspecifics of similar size versus habitats without conspecific cues. Tested frogs did not show a preference for habitats containing only scent from conspecifics but did prefer habitats where conspecifics were present. Our results show that conspecific attraction is a determining factor in juvenile green and golden bell frog habitat selection. To our knowledge, this is the first time the behaviour is shown to occur in juvenile frogs in the habitat selection context. From a conservation management point of view, the behaviour may help to explain the failure of reintroductions to areas where the frogs have been extinct, and the non-occupation of suitable created habitats in areas where they still inhabit and develop appropriated management strategies.]]> Sat 24 Mar 2018 07:10:02 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:34893 Mon 23 Sep 2019 12:23:10 AEST ]]>
