BackgroundThe Mountain Pygmy-possum (Burramys parvus) is a critically endangered marsupial, endemic to alpine regions of southern Australia. We investigated the diet of a recently discovered population of the possum in northern Kosciuszko National Park, NSW, Australia. This new population occurs at elevations well below the once-presumed lower elevation limit of 1,600 m.Goals and MethodsFaecal material was analysed to determine if dietary composition differed between individuals in the newly discovered northern population and those in the higher elevation southern population, and to examine how diet was influenced by rainfall in the southern population and seasonal changes in resource availability in the northern population.Results and DiscussionThe diet ofB. parvusin the northern population comprised of arthropods, fruits and seeds. Results indicate the diet of both populations shares most of the same invertebrate orders and plant species. However, in the absence of preferred food types available to the southern population, individuals of the northern population opportunistically consumed different species that were similar to those preferred by individuals in higher altitude populations. Differing rainfall amounts had a significant effect on diet, with years of below average rainfall having a greater percentage composition and diversity of invertebrates. Seasonal variation was also recorded, with the northern population increasing the diversity of invertebrates in their diet during the Autumn months when Bogong Moths (Agrotis infusa) were absent from those sites, raising questions about the possum’s dependence on the speciesConclusionsMeasurable effects of rainfall amount and seasonal variation on the dietary composition suggest that predicted climatic variability will have a significant impact on its diet, potentially impacting its future survival. Findings suggest that it is likely thatB. parvusis not restricted by dietary requirements to its current pattern of distribution. This new understanding needs to be considered when formulating future conservation strategies for this critically endangered species.

The distribution of the three Italian species of Rhysodidae was reviewed by re-examining published data, museum conserved and newly collected specimens. Rhysodes sulcatus chronogeonemy encloses a large majority of old findings and only two recently confirmed active populations are recorded after the year 2000. Omoglymmius germari shows a similar picture, with only one recent record (2018) in the Pollino National Park (Basilicata) but a small number of active populations after 2000. Clinidium canaliculatum populations are in a much better conservation status, with about 50 new sites detected after 2000 in the Sila National Park. Threats and research/monitoring needs have been discussed for each species and new IUCN status proposed for Italian populations: Critically Endangered (CR) for Rhysodes and Omoglymmius, Near Threatened (NT) for Clinidium.

The Way

The Sumatran rhino Dicerorhinus sumatrensis is regarded as critically endangered with a world population of approximately 400. In 1991 it was recorded in Way Kambas National Park, Sumatra, Indonesia, 30 years after the park's last rhino was believed to have been shot. A Sumatran Rhino Population and Habitat Viability Analysis (PHVA) workshop in 1993 recommended an immediate survey be carried out to assess the rhino population in the park. The Way Kambas Project recorded observations of rhino sign between 1993 and 1995. Sign was most frequently observed along trails in mature secondary forest. Data from the areas surveyed suggest the presence of at least four rhinos.

We describe five new species of Miconia (Melastomataceae) from Yanachaga Chemillén National Park and vicinity in Pasco, Peru: Miconia cardenasiae, Miconia chemillensis, Miconia humifusa, Miconia odoratissima, and Miconia pozuzoana. These species occur across a range of ecological habitats in the central Andes of Peru. Two of these species exhibit modifications for plant-arthropod interactions as leaf domatia and one of them has hollow stems. The number of previously undescribed species presented here from a relatively small area underscores the continued need for alpha taxonomy in the tropical Andes. Based on restricted distribution and habitat degradation pressure, we recommend that all species be categorized as either Endangered or Critically Endangered under IUCN guidelines.

AbstractThe Critically Endangered hirola Beatragus hunteri exists in two populations, a natural population on the Kenyan–Somali border and a translocated population in Tsavo East National Park, Kenya. The Tsavo population is becoming increasingly important for the survival of the hirola yet its status is unknown and little is understood about the factors that limit its growth. Here we report the size, distribution and demographic parameters of the Tsavo population of hirola and consider whether insufficient suitable habitat could be limiting its growth. The Tsavo population has not increased since 2000, when the last census was carried out, but neither has it significantly decreased. The importance of habitat as a limiting factor is dependent on the hirola's ability to utilize marginal habitat.

Two Populations

Many threatened species occur as small, isolated populations. Understanding the extent and genetic distinctiveness of these populations is essential for management. Nangura spinosa is a critically endangered skink known from two small populations in dry rainforest in south-east Queensland. We conducted targeted surveys between 2001 and 2010 at the two known N. spinosa sites (Nangur National Park, Oakview National Park area) and in 22 nearby forest blocks with potentially suitable habitat. N. spinosa was found only at the two previously known sites, which are ~36 km apart. The skink appears to be declining at Nangur NP, to an estimated extent of occurrence of 7.4 ha and potentially no more than 35 adults. In contrast, we increase the extent of occurrence at Oakview to 360 ha, where the population is at least in the hundreds. Sequencing of two mtDNA genes revealed considerable genetic divergence between the two populations (3.8% for ND4; 1.2% for 16S), suggesting an extended period of separation. Population fragmentation is therefore not the result of recent land clearing, but of long-term isolation by unsuitable habitat. Each population should be considered a distinct management unit. More data are required on population size and trends, recruitment and threats, particularly for the Nangur population.

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.
