“…3). The diel activity of the flat-headed cat in our study was consistent with that observed by Adul et al (2015) in central Kalimantan (Fig. 3); the species is nocturnal and is often detected during surveys by boat at night (Hearn et al, 2010; Mohd-Azlan & Thaqifah, 2020).…”

Sarawak is the largest state in the megadiverse country of Malaysia. Its rich biodiversity is threatened by land-use change and hunting, with mammalian carnivores particularly affected. Data on the ecology, occurrence and distribution of small carnivores are crucial to inform their effective conservation, but no large-scale assessments have previously been conducted in Sarawak. Here we examine the status of the five species of felids in Sarawak based on data from camera-trap studies over 17 years (May 2003–February 2021) across 31 study areas, including protected areas of various sizes, production forests and forest matrix within oil palm plantations. Felids were detected at 39% of 845 camera stations. The marbled cat Pardofelis marmorata and Sunda clouded leopard Neofelis diardi had higher probabilities of occurrence in protected than unprotected areas, and vice versa for the leopard cat Prionailurus bengalensis and bay cat Catopuma badia. The marbled and bay cats were mostly diurnal, and the leopard cat was predominantly nocturnal; activity patterns did not substantively differ between protected and unprotected sites. The probabilities of occurrence of marbled and bay cats increased with greater distance from roads. The leopard cat and flat-headed cat Prionailurus planiceps were more likely, and the clouded leopard less likely, to occur near rivers. Flat-headed cats preferred peat swamp forest, bay cats lowland forest, and marbled cats and clouded leopards occurred in both lowland and montane forest. Felids may tolerate higher elevations to avoid anthropogenic disturbance; therefore, it is critical to preserve lowland and mid-elevation habitats that provide refugia from climate change and the destruction of lowland habitat.

“…The study showed that clouded leopard activity was predominantly nocturnal (Adul et al., 2015; Azlan & Sharma, 2006; Grassman et al., 2005a; Mukherjee et al., 2019) with bimodal peaks at 1900–2300 hr and 0200–0400 hr. Although overall radiotelemetry studies reported distinct activity peaks in the morning followed by evening crepuscular hours (Austin et al., 2010; Grassman et al., 2005a).…”

Temporal interactions and moon illumination effect on mammals in a tropical semievergreen forest of Manas National Park, Assam, India

et al. 2021

Species interactions play a vital role in structuring mammalian communities by stimulating behavioral responses in varied niche dimensions that affect sympatric associations and predator-prey relationships. We determined temporal overlap and effects of the moon cycle on dominant and sub-dominant mammalian assemblages in Manas National Park, India. A total of 36 species were captured, with 24,865 independent records over 11,294 trap nights. We collected 1,130 photographs of five large-and medium-sized carnivores and 1,541 photographs of 12 small carnivores. Fifty-one percent of records were detected during diurnal period, followed by 38% in nocturnal phase, and 11% during twilight. Small carnivores such as Prionailurus bengalensis and Viverridae spp. were strictly nocturnal, whereas Martes flavigula and Herpestidae spp.were diurnal. Medium-sized carnivores were either nocturnal (Neofelis nebulosa) or diurnal (Cuon alpinus), whereas large-sized carnivores (Panthera tigris, Panthera pardus, and Ursus thibetanus) were cathemeral. A high degree of temporal overlap (>0.75) was found between most sympatric carnivores with distinct activity peaks, while a low overlap (<0.50) was observed between different body-sized carnivores. Viverrids' activity was negatively correlated (r = −0.44, p < 0.01) with lunar cycles, perhaps to increase foraging efficiency or as an anti-predator strategy. Large prey (μ = 133.23°) and small prey (μ = 131.35°) activity were high during brighter nights due to better visual detection in detecting or avoiding predators. Dominant species activity was least affected by the lunar cycle among forest-dependent mammals, whereas subdominant species activity was either lunarphobic or lunarphilic. The study demonstrates the use of passive camera traps in understanding the behavioral rhythms of tropical mammals.

“…The Captures cameras use an infrared flash. There are some logging roads in some of the study areas, all cameras were placed along established trails at cross-roads and near fallen logs or man-made boardwalks, which may facilitate felid movements during the flooded wet season, as cameras were primarily placed to capture felids [Adul et al, 2015; further information in Cheyne et al, 2013].…”

A Short Cut to Mushrooms – Red Langur (Presbytis rubicunda) Consumption of Terrestrial Fungus

We report the first in-depth evidence of targeted mushroom foraging in an Asian colobine. Using direct observations (2010–2018) and camera traps (2008–2018) in the Sebangau Forest, Central Kalimantan, Indonesian Borneo, we show how adult female red langurs (Presbytis rubicunda) are regularly descending to the ground to consume mushrooms. We recorded 82 counts (0.36% of all focal observations, n = 25,502) of the focal adult langur on the ground from direct observations of habituated groups, and 80 independent images/videos of red langurs on the ground were obtained from the camera traps representing 1.12% of total images (n = 7,145). Mushroom consumption took place in 4 families, representing 0.04% of total focal behaviour observations and 24.3% of total time feeding on the ground. From the camera trap photos, red langurs are spending 20% of time on the ground feeding. We speculate that mushrooms could be a supplementary food for adult female langurs as there is an increase in consumption in April and November.
