A large number of forests at Munggu Village, Ngabang District, Landak Regency have been converted into oil palm and rubber plantations. As consequences, natural habitats in the region have been fragmented and species diversity, including herpetofauna, has been decreased. This study aimed to assess herpetofauna diversity in four different habitats in Munggu Village: (1) forests, (2) Landak river, (3) tourist areas, and (4) rubber plantations. Data collection used Visual Encounter Survey (VES) for 8 days.[u1]  The results showed that the total of 24 herpetofauna species: 15 amphibians’ species (4 families) and 9 reptiles species (6 families) have been recorded from the four sampled areas. Of the four locations 11 species were found in river habitat in the forest, 4 species in the location of Landak river, 8 species in tourism sites and 9 species in rubber plantations. The Shannon-Wiener (H') diversity index in all four habitats was classified as moderate. In the river location in the forest, H' was 2.14, in the Landak river it was 1.28, in the tourism sites it was 1.71 and in the rubber plantation it was 1.87. However, the evenness index (E) for the herpetofauna community in all four locations was >0.80. Habitat loss and habitat destruction are among the causes of decline in amphibian and reptile populations. Knowing the diversity of herpetofauna, it is hoped that the community and stakeholders can collaborate to secure the herpetofauna in Munggu Village.

Movement patterns has been observed in black-spotted rock frog (Staurois gutattus). The aim of this study was to obtain data movement patterns. This research was conducted at Mountain Poteng, West Kalimantan. Data were analized graphically to explain the relationship between the used parameters. There are 20 individual frogs were observed for 24 hours by using a spool track, which consists of 10 males and females. Chi square test result values of alignment grooves conducted on 20 individual frogs were observed during the 24 hours of observation showed that the χ2 count < χ2 table with a value of (χ2 = 0,61 < 3,481, p = 0,05; Chi square test), it shows that the pattern of movement of male and female frogs do not stay away from the starting point of observation.

The behavior of both acoustic and visual signals has been observed in Staurois gutattus black-spotted rock frogs. The aim of the study was to determine how S. gutattus frogs communicate to find their mates through acoustic and visual signals. This research was conducted in Mount Poteng, West Kalimantan. Data were analyzed descriptively and graphically to explain the relationship between the measured parameters. Data collection of advertisement call, foot-flagging and amplexus behavior is done directly in the field. All activities carried out are recorded with the camera. The duration of each part of the breeding activity is also calculated using a stopwatch. The male frog's advertisement call and foot-flagging are carried out by the male frogs while attracting their mates to mate. Where the foot-flagging activity was mostly carried out on the rock substrate (62%), while on the leaf substrate advertisement call was more dominant (47%). Then based on the duration, activity advertisement call, foot-flagging and amplexus the longest duration was performed by male frogs in the time range 18.00-05.59. Meanwhile, from the number of individuals, the advertisement call, foot-flagging and amplexus activities were mostly carried out at 18.00-05.59.
