Bat survey was conducted in Bako National Park from 25th to 29th August 2013. A total of 107 individuals from11 species of bats were recorded. Hipposideros cervinus was recorded as the most abundance species with 51individuals while Murina suilla and Rhinolophus affinis were the least abundant with one individual each fromtotal captures. This study has added R. affinis as another new species locality record for the national park. Thisbrings up the total bat species known from the park now to 35 species of bats. Interestingly, an individual of H.cervinus with partial albinism was caught during this survey. This single bat was captured on the 27th August2013 and will be the first albino bat reported in Borneo and possibly Malaysia. This specimen is an adultfemale that presents high degree of albinism over most of the body but lacking on the upperparts of the bodyand part of the wings. Detailed description based on 16 external and craniodental measurements are presentedherein along with their species identification through genetic analyses. Further research on the genetic structureand behavior of an albino individual may help to identify the possible causes and consequences of albinism tothe bats populations.
Small mammal surveys were conducted at Niah National Park, Lambir Hills National Park and Gunung Mulu National Park, Miri Division, in the northeastern region of Sarawak, using ground-level and canopy mist-nets, harp traps, and cage traps. The main objective of these surveys was to assess small mammal diversity in the northeastern region of Sarawak. Gunung Mulu National Park recorded the highest diversity of small mammals with 29 species, followed by Niah National Park with 19 species, and Lambir Hills National Park, 17 species. These surveys revealed nine new locality records for Miri, including eight bat species (Dyacopterus spadiceus, Megaerops wetmorei, Nycteris tragata, Hipposideros cineraceus, Hesperoptenus blanfordi, Kerivoula pellucida, Murina suilla and Myotis muricola)and a squirrel (Sundasciurus brookei). Megaerops wetmorei is also reported for the first time in Sarawak.
Tarsier is an endangered nocturnal primate in the family Tarsiidae and is an endemic to Sundaic islands of Philippine ( Carlito syrichta ), Sulawesi ( Tarsius tarsier-complex) and Borneo ( Cephalopachus bancanus ). Recent records indicated that most molecular studies were done on the Eastern Tarsier and little information for the other group of tarsiers. Here, we present a partial cytochrome b data set of C. bancanus in Sarawak, Malaysian Borneo. Standard mist nets were deployed at strategic locations in various habitat types. A total of 18 individuals were caught, measured and weighed. Approximately, 2 × 2 mm of tissue samples were taken and preserved in molecular grade alcohol. Out of 18, only 11 samples were screened with partial mtDNA (cytochrome b ) and the DNA sequences were registered in the GenBank (accession numbers: KY794797-KY794807). Phylogenetic trees were constructed with 20 additional mtDNA sequences downloaded from GenBank. The data are valuable for the management authorities to regulate the type of management units for the metapopulation to sustain population genetics integrity of tarsiers in the range countries across the Sunda Shelf.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
