The Earless monitor (Lanthanotus borneensis Steindachner, 1878) is a rare and endemic species of lizard to the island of Borneo. Individuals of this species were often culled to supply the international pet market and have been kept in captivities, also in the northern temperate areas. This study aimed to describe the daily activities of L. borneensis at the reptile house of Museum Zoologicum Bogoriense (MZB), a live animal research facility of the former Indonesian Institute of Sciences (LIPI) - now merged into BRIN. Focal animal sampling was used to observe L. borneensis behavior for two hours per individual in the morning (09:00–11:00) and afternoon (15:15–17:15) with the assistance of surveillance cameras (CCTV), resulting in a total observation time of 16 hours per individual per two months. The observations of 10 individuals of L. borneensis showed that they were more inactive in the morning, with a tendency to be more active and feeding in the afternoon. During inactivity, lizards remained motionless in the bamboo; when active, they were moving in water and foraging.

Indonesia has two of the three amphibian orders, Gymnophiona and Anura. Frogs in Indonesia have ten families. In West Java, there are 28 Anura species from six families. In general, frog habitats are very diverse and can be found in urban areas. However, the distribution in the IPB Dramaga campus, especially in the lake ecosystem is still unknown. Therefore, this research aims to determine the diversity and distribution of the Anura order in the Lake Ecosystem of IPB Dramaga. The method used is the Visual Encounter Survey (VES). The research locations are the three lakes ecosystem at IPB Dramaga (SDGs, Inspirasi Lake, LSI). This research recorded eight species, including Duttaphrynus melanostictus, Ingerophrynus biporcatus, Fejervarya cancrivora, Limnonectes macrodon, Hylarana erythraea, Amnirana nicobariensis, Microhyla achatina, and Polypedates leucomystax. Species D. melanostictus and F. cancrivora are distributed throughout the lake. This study recorded that the Shannon-Wiener diversity in the IPB Dramaga Lake ecosystem (SDGs, Telaga Inspirasi, LSI) was in the medium category (1.28–1.71). Brillouin Diversity Index is in the high category (1.18– 1.50). The evenness index (0.82–0.92) was close to even. Simpson's Dominance Index (0.21–0.30) and Margalef's Species Richness (1.17–1.91) were low.

Anjing domestik (Canis lupus familiaris) dari famili Canidae merupakan salah satu spesies anjing yang telah melalui proses domestikasi. Masing-masing pemilik anjing akan memperlakukan hewan peliharaannya secara berbeda yang mengakibatkan perbedaan perilaku. Di antara lokasi-lokasi di kampus IPB Dramaga, lingkungan penangkaran Pusat Studi Satwa Primata menjadi salah satu tempat di mana anjing peliharaan banyak dijumpai. Metode focal animal sampling untuk mengamati perilaku anjing dengan interval waktu 10 menit dan data perilaku harian dibagi dalam 7 kategori yaitu ekskresi, lokomosi, perawatan diri, sosial, vokalisasi, inaktif dan negatif. Pada periode pengamatan dari pukul 09.00 hingga 13.00, tiga individu anjing menunjukkan perilaku istirahat dalam rentang 51-69% dan memilih lokasi yang dekat dengan pemilik untuk beraktivitas.
