“…The high dominance of Canarium asperum explains the high encounters of cuscus on this tree; On Salibabu Island, 3 out of 11 encounters were observed, Bukide Island, two out of three encounters, and Nusa Island, two out of four encounters. This is also supported by Repi et al (2019) who reported that C. asperum is one of the species most consumed by A. melanotis on Salibabu Island, apart from M. peltata and C. odorata. Data on tree level and pole level vegetation is very important in describing the habitat of A. melanotis, this is because, as an arboreal marsupial, A. melanotis utilizes higher level vegetation structure to move and rest, and is highly dependent on forest vegetation density (Repi et al 2019).…”

“…A brief survey on Salibabu Island by Riley (2002) did not find any individual cuscus, and an intense 120-day survey on Sangihe Island found only a single captive individual. However, recently there was a publication about daily activity and diet of A. melanotis on Salibabu Island by Repi et al (2019), which confirmed the existence of A. melanotis here. But in general, until now the distribution assumptions and population status were based solely on local information.…”

“…In relation to species distribution, Mott (2012) states that the spatial gradient in climate variables is one of the factors limiting the geographic distribution of species. Repi et al (2019) reported that there was a strong positive correlation between temperature and resting activity and conversely a strong negative correlation with feeding and moving activities in the behavior of A. melanotis. This may be the cause of the small probability of finding the movement of the cuscus during the day.…”

“…This may be the cause of the small probability of finding the movement of the cuscus during the day. Therefore, further research with the cuscus population survey method at night is necessary, considering that there is no certainty whether it is nocturnal or diurnal (Dwiyahreni et al 1999;Repi et al 2019).…”

Abstract. Repi T, Masy’ud B, Mustari AH, Prasetyo LB. 2020. Population density, geographical distribution and habitat of Talaud bear cuscus (Ailurops melanotis Thomas, 1898). Biodiversitas 21: 5621-5631. The Talaud bear cuscus (Ailurops melanotis) has been reported from Sangihe (the largest island in the Sangihe Island group) and Salibabu (within the Talaud Islands). As an endemic species of Indonesia, this species is rare and there is no certainty regarding its precise geographic distribution or population size. This research aimed to estimate population density and provide the first preliminary data on its geographical distribution, as well as general description of its habitat. Our research shows that A. melanotis occurs on three islands: Salibabu Island, Nusa Island, and Bukide Island, and probably also exists in the Sahandaruman mountain on Sangihe Island. Our population surveys estimate, population density on each island as: Salibabu: 3.69 ± 2.54 ind/km2, with an estimated total population of 28.95 individuals, Nusa Island: was 12.31 ± 2.58 ind/km2, with an estimated population of 19.08 individuals, and Bukide Island: 7.17 ± 1.79/km2, with an estimated population of 10.40 individuals. Information regarding population is a key guiding factor in conservation efforts, where population size is related to extinction risk (threat status) and its geographical distribution, this can help to determine conservation priorities for species or habitats.

Functional traits of the world’s late Quaternary large-bodied avian and mammalian herbivores

et al. 2021

View full text Add to dashboard Cite

Prehistoric and recent extinctions of large-bodied terrestrial herbivores had significant and lasting impacts on Earth’s ecosystems due to the loss of their distinct trait combinations. The world’s surviving large-bodied avian and mammalian herbivores remain among the most threatened taxa. As such, a greater understanding of the ecological impacts of large herbivore losses is increasingly important. However, comprehensive and ecologically-relevant trait datasets for extinct and extant herbivores are lacking. Here, we present HerbiTraits, a comprehensive functional trait dataset for all late Quaternary terrestrial avian and mammalian herbivores ≥10 kg (545 species). HerbiTraits includes key traits that influence how herbivores interact with ecosystems, namely body mass, diet, fermentation type, habitat use, and limb morphology. Trait data were compiled from 557 sources and comprise the best available knowledge on late Quaternary large-bodied herbivores. HerbiTraits provides a tool for the analysis of herbivore functional diversity both past and present and its effects on Earth’s ecosystems.

The population of the bear cuscus Ailurops ursinus (Temminck, 1824), an arboreal marsupial endemic to Sulawesi, Indonesia, and its satellite islands, is declining rapidly due to poaching and habitat loss, even in protected areas. However, despite concerns over its persistence, little is actually known of this secretive species. This research investigated the characteristics of the selected habitats and diet of the bear cuscus in four ecosystem types (lowland non-dipterocarp forest, lowland limestone forest, lowland monsoon deciduous forest, lowland monsoon evergreen forest). Habitat use data were collected through direct encounters and indirect observations (tracks, signs, secondary information), and analyzed using a chi-square goodness-of-fit test. Habitat characteristics and diet availability were determined using vegetation analysis. Diet data were obtained using direct observations, feed remains, and interviews. The lowland non-dipterocarp forest ecosystem was used significantly more by bear cuscus populations. Its habitats across the four ecosystem types had similar environmental conditions. Fifty-five plant species, eaten mostly as young leaves and leaf buds, encompassed the bear cuscus’ diet, with the Moraceae family being the most representative. Considering the ubiquity of Moraceae in the bear cuscus’ habitat, these results highlight the impact unchecked deforestation will continue to have on lowland Indonesia and its endemic species.
