"Siamang hidup berdampingan dengan berbagai spesies mamalia arboreal yang berpotensi sebagai kompetitor di Taman Nasional Bukit Barisan Selatan (TNBBS). Tujuan penelitian ini adalah untuk mengetahui apakah terjadi kompetisi antara siamang dan mamalia arboreal lainnya serta mengetahui tumpang-tindih relung berdasarkan penggunaan habitat dan pemilihan pakan di antara komunitas mamalia arboreal di Stasiun Penelitian Way Canguk, TNBBS. Pengambilan data dilakukan pada bulan Februari hingga April 2014 dengan dua metode, yaitu metode focal instantaneous sampling untuk pengamatan perilaku siamang dan metode transek garis untuk survei mamalia arboreal. Hasil penelitian menunjukkan bahwa siamang berkompetisi dengan simpai, bajing kelapa, dan jelarang hitam. Tumpang-tindih relung terbesar terjadi antara siamang dengan jelarang hitam berdasarkan pemilihan pakan (Ro = 0,418) dan penggunaan habitat (Uji Wilcoxon, p-value > 0,05). Dari 57 interaksi interspesifik antara siamang dan mamalia arboreal lainnya, terdapat 61,40% interaksi netral, 19,30% agresi, dan 19,30% dominansi. Kesimpulan penelitian ini adalah kompetisi interferensi dan eksploitatif terjadi antara siamang dan ketiga spesies mamalia arboreal serta terdapat tumpang-tindih relung antara siamang dan ketiga spesies mamalia arboreal.

Siamang coexists with various arboreal mammal species which are potential competitors to siamang in Bukit Barisan Selatan National Park (BBSNP). The aims of this study are to determine whether interspecific competition occurs between siamang and other arboreal mammals and to determine niche overlap in terms of habitat use and food selection among mammals community in Way Canguk Research Station, BBSNP. Data collection was conducted on February until April 2014 using two methods: focal instantaneous sampling to measure siamang behavior and line transect method to survey coexisting mammals.

The result of this research suggests that siamang competes with banded langur, plaintain squirrel, and black giant squirrel. Niche overlap is the highest between siamang and black giant squirrel based on food preference (Ro = 0,418) and habitat use (Uji Wilcoxon, p-value > 0,05). Among 57 interspecific interactions between siamang and other arboreal mammals, 61,40% are netral interactions, 19,30% are agressions, and 19,30% are dominance interactions. This research concludes that interference and exploitative competition occur between siamang and three other arboreal mammals and there is niche overlap among them."

"Keberadaan satwa mamalia memiliki peran penting dalam ekosistem hutan, yaitu sebagai penyubur tanah, penyerbuk bunga, dan pemencar biji. Tujuan dari penelitian ini adalah menganalisis keanekaragaman dan dominansi mamalia yang berada pada lokasi pemasangan camera trap pada DAS Katingan di kawasan restorasi lahan gambut Katingan Mentaya Project, Kalimantan Tengah. Penelitian ini dilakukan dengan mengolah data camera trap yang terpasang di lokasi pemasangan camera trap di DAS Katingan. Data yang digunakan merupakan data camera trap yang telah dipasang dari tahun 2019—2021 (3 tahun) di lokasi pemasangan camera trap pada DAS Katingan yang terdiri dari Klaru, Bakumin, dan Hantipan. Hasil penelitian menunjukkan bahwa jumlah jenis mamalia yang berhasil dideteksi camera trap pada ketiga lokasi pemasangan camera trap adalah sebanyak 43 spesies dari 20 famili dan 7 ordo. Dari 43 spesies tersebut terdapat 6 jenis mamalia yang merupakan satwa endemik Kalimantan, yaitu orangutan kalimantan (Pongo pygmaeus), owa kelawo (Hylobates albibarbis), bekantan kahau (Nasalis larvatus), lutung buhis (Presbytis rubicunda), kijang kuning (Muntiacus atherodes), dan sukau pukang (Exilisciurus exilis). Nilai Indeks Keanekaragaman Shannon-Weiner (H’) pada DAS Katingan adalah 2,82 sehingga dikategorikan kenanekaragaman sedang, nilai Indeks Kemerataan Simpson (E) 0,75 sehingga dikategorikan kemerataan populasi tinggi, nilai Indeks Dominansi Simpson (D) 0,08 sehingga tidak ada spesies yang mendominansi. Lima jenis mamalia dengan nilai kelimpahan jenis dan encounter rate (ER) tertinggi secara urutan adalah babi nangui (Sus barbatus), monyet beruk (Macaca nemestrina), bajing kelapa (Callosciurus notatus), beruang madu (Helarctos malayanus), dan tupai akar (Tupaia glis).

The existence of mammals has an important role in forest ecosystems, namely as soil fertilizer, flower pollinator, and seed spreader. The purpose of this study is to analyze the diversity and dominance of mammal at the camera trap installation location in Katingan Watershed in the peatland restoration area of ​ Katingan Mentaya Project, Central Kalimantan. This research was conducted by processing camera trap data at the camera trap installation location in the Katingan Watershed. The camera trap data used in this study is camera trap data that has been installed from 2019-2021 (3 years) at the camera trap installation location in the Katingan Watershed which consists of Klaru, Bakumin, and Hantipan. The results showed that the number of mammal species detected by the camera trap at the three camera trap installation location is 43 species from 20 families and 7 orders. From 43 species, there are 6 types of mammals which are endemic to Kalimantan, namely borneo orangutan (Pongo pygmaeus), white bearded gibbon (Hylobates albibarbis), proboscis monkey (Nasalis larvatus), maroon leaf monkey (Presbytis rubicunda), bornean yellow muntjac (Muntiacus atherodes), and plain pygmy squirell (Exilisciurus exilis). The Shannon-Weiner Species Diversity Index (H') value in the Katingan Watershed is 2.82 so it is categorized as moderate diversity, Evenness Index (E) value is 0.75 so it is categorized as high population evenness, Dominance Index (D) value is 0.08 so there is no dominating species. The five species of mammals with the highest Species Abundance and Encounter Rate (ER) values ​​in order are the banded pig (Sus barbatus), pig-tailed macaque (Macaca nemestrina), plantain squirell (Callosciurus notatus), sun bear (Helarctos malayanus), and common treeshrew (Tupaia glis)."

"This book describes the physiology of mammals in an ecological and environmental context. It first describes the basic bauplan and history of living mammals from an evolutionary viewpoint. General physiological principles are then presented, including the importance of body size and regulatory control systems. This is followed by a detailed description of the physiological characteristics of mammals with respect to energetics, thermoregulation, respiration, circulation, feeding and digestion, water and solute balance, neurobiology, and reproduction. Environmental adaptations are then described for mammals in extreme environments (cold, hot, underground, high altitude, and aquatic), using specialized locomotor styles (cursorial, brachiation, migration, gliding, and powered flight), and exploiting difficult-to-digest diets (keratin, bone, waxes, chitin, and plant material). Current concepts, approaches, techniques, and applications in mammalian research are then discussed, starting with the use of the comparative method to interpret evolutionary adaptations in a phylogenetic context. This is followed by basic concepts for measurement of mass, temperature, and humidity. The use of remote sensing and stable and radioactive isotopes for the study of free-living mammals. The rapid development of molecular biology techniques in mammalian physiology. And the implications of ecological and environmental physiology to mammalian distributions now and in the future. Conclusions and future directions focus on effects of climate change on mammals, the implications of phenotypic plasticity and epigenetics, the expanding role of physiology and ecology in conservation, and the future role of mammals in medical and veterinary research, and in agriculture.
