The natural distribution of the critically endangered northern hairy-nosed wombat (Lasiorhinus krefftii) is confined to Epping Forest National Park, Queensland; however, a small number of animals have been translocated to establish an insurance population at Richard Underwood Nature Refuge (RUNR), Queensland. Northern hairy-nosed wombat behaviour is poorly understood, mostly due to its cryptic behaviour. Thirty-two wildlife cameras set up at burrow mouths at RUNR were used to capture social and solitary behaviour. Over a six month period between December 2016 and May 2017, 0.3% (21 videos of 6607) of recordings captured social behaviour, suggesting that the northern hairy-nosed wombat actively avoids social interactions at the burrow mouth. Vocalisation was only observed during social interaction. The results were similar to data from Epping Forest National Park and studies on other wombat species. In this respect the translocated population appeared to behave in a manner typical of the wild population.

In this paper we report on the application of infrared digital cameras to investigate aspects of the breeding biology of the spotted-tailed quoll, an endangered marsupial carnivore. Technical details are provided about the cameras, which were deployed remotely at two ‘latrine’ sites used by the target species within Kosciuszko National Park in southern New South Wales, Australia. Examples of images captured by the cameras are presented, with notes on possible application of the same technology to better understand the social behaviour of rare and cryptic species.

Abstract Veissière and colleagues make a valiant attempt at reconciling an internalist account of implicit cultural learning with an externalist account that understands social behaviour in terms of its environment-involving dynamics. However, unfortunately the author's attempt to forge a middle way between internalism and externalism fails. We argue their failure stems from the overly individualistic understanding of the perception of cultural affordances they propose.

Although the general ultrastructure of Cyanidium caldarium, an acidophilic, thermophilic alga of questionable taxonomic rank, has been extensively studied (see review of literature in reference 1), some peculiar ultrastructural features of the chloroplast of this alga have not been noted by other investigators.Cells were collected and prepared for thin sections at the Yellowstone National Park and were also grown in laboratory cultures (45-52°C; pH 2-5). Fixation (glutaraldehyde-osmium), dehydration (ethanol), and embedding (Epon 812) were accomplished by standard methods. Replicas of frozenfracture d- etched cells were obtained in a Balzers apparatus. In addition, cells were examined after disruption in a French Press.
