“…On the first day of the feeding trials at 16:00, we provided 60 g of O. formosanus (18,816 individuals estimated by mass) or 15–20 g of A. gracilipes (14,400–19,200 individuals estimated by mass) mixed thoroughly with artificial food and 0.25 g of Cr 2 O 3 (a maker that produces green feces) to form a 100 g diet for each pangolin. The number of termites or ants used in this study is similar to that found in the gut of a wild Chinese pangolin reported by Lee et al (2017). Although the body length of termites and ants are quite similar (Figure 1a,b), termites contain more water than do ants (Redford & Dorea, 1984).…”

“…Several previous studies have reported proportions of termites in free‐ranging pangolin diets, although the results were not consistent. Lee et al (2017) dissected the gut of one Chinese pangolin and found that termites constituted only 3.1% of the insect individuals in the gut, and the rest were ants. In research on the Indian pangolin ( M. crassicaudata ), termite cuticles remaining in the feces constituted a small percentage of the gut content (Irshad et al, 2015) or were not recovered (Mahmood et al, 2013).…”

“…The fungus‐growing termite, Odontotermes formosanus (Shiraki, 1909), and the yellow crazy ant, Anoplolepis gracilipes (Smith, 1857), are major food sources for the Chinese pangolin (Lee, Cheung, Fellowes, & Guénard, 2017; Wu et al, 2005). Odontotermes formosanus were collected from shelter tubes on tree trunks by using a vacuum (SEPARATING, Model: SEPRE‐1) at 17 locations in the National Chung Hsing University and Tunghai University of central Taiwan during June–August 2016 and the termites were immediately separated from the soil and other debris.…”

Digesta retention time and recovery rates of ants and termites in Chinese pangolins (Manis pentadactyla)

Pangolins are myrmecophagous mammals whose biology and ecology remain poorly studied. Termite mandibles and ant head capsules are the two primary remains found in pangolin feces. Determining the retention time of insect cuticles is important for understanding the digestive physiology of pangolins, while determining the recovery rate of termites and ants in feces is required to estimate the number of these prey items that are consumed by pangolins. In this study, the authors conducted feeding trials with captive Chinese pangolins (Manis pentadactyla). Sixty grams of the fungus-growing termite Odontotermes formosanus (18,816 individuals) and 15-20 g of the yellow crazy ant Anoplolepis gracilipes (14,200 individuals) were fed to each pangolin. After feeding, pangolin feces were collected daily for 1 week. The authors also assessed the accuracy of using chromium (III) oxide powder (Cr 2 O 3 ) as a proxy for determining gut passage time, as has been done in previous studies. The results showed that remaining termite mandibles and ant head capsules in feces peaked at 66 and 90 hr after feeding and their recovery rates were 0.35 ± 0.10 and 0.65 ± 0.04, respectively. In both feeding trials, the retention time of Cr 2 O 3 was much shorter than that of the termite mandibles and ant head capsules, indicating that Cr 2 O 3 is not an appropriate indicator for estimating food retention time of myrmecophagous animals. Our results revealed that the ant head capsules were preserved better in feces compared with the termite mandibles, suggesting that termites may be considerably underestimated in the feces of wild pangolins.

Potential Distribution of the Critically Endangered Chinese Pangolin (Manis pentadactyla) in Different Land Covers of Nepal: Implications for Conservation

et al. 2020

Anthropogenic activities have driven many wildlife species towards extinction. Among these species, the geographic distributions of many are poorly documented, which can limit the effectiveness of conservation. The critically endangered Chinese pangolin (Manis pentadactyla) is experiencing population decline throughout its range due to land-use changes and illegal trade for food and traditional medicine. Using distribution records and maximum entropy modeling, we predicted the potential distribution of the Chinese pangolin across Nepal. Most suitable potential habitats of the Chinese pangolin occurred in forest areas of the mid-hill region in central and eastern Nepal, followed by cultivated land. Almost all potential suitable habitats of the Chinese pangolin occurred outside of protected areas, and most of them were encroached upon by cultivated land, human settlements, and infrastructure developments. The results from this study provide baseline information on the potential suitable habitats of the Chinese pangolin in Nepal, which helps to develop site- and species-specific management plans and to identify priority areas to minimize the current threats to the pangolin and enhance the stewardship of species conservation.

“…Studies in peri-urban landscapes of the global south show that peri-urban landscapes can be vital biodiversity conservation areas [33][34][35][36][37][38][39][40] giving us a chance to maintain and protect the numerous and unaccountable ES benefits biodiversity provides to mankind [27,41,42]. In the Philippines, the majority of the ES related studies include traditional rice-based systems and their watershed services [43][44][45], mangroves [46,47], and indigenous agriculture-based systems in ancestral land [48].…”

This study investigates different provisioning services in the peri-urban landscapes of Manila conurbation through a case study of two villages in the Jala-Jala municipality of the Laguna de Bay area in the Philippines. Laguna de Bay is an ecologically productive and important watershed for the urban and peri-urban areas of Manila for the provision of food, freshwater, and other materials. However, the lake and its ecosystem are under threat because of rapid urbanization and associated land-use changes. This study is based on a semi-quantitative survey conducted with 90 households in two villages: Special District and Paalaman. It was aimed to capture how provisioning services in the locality are connected with local livelihoods. The results obtained from the study suggest that landscapes in this peri-urban area still has considerable provisioning ecosystem services associated with local biodiversity and that this dependence on provisioning services and their relationship to peri-urban landscapes and biodiversity should be addressed for sustainable landscape management. The results have important implications for the conservation potential of biodiversity on which local livelihoods depend, in urban and peri-urban ecosystems.
