dc.description.abstractMamalia kecil non-volant, khususnya dari ordo Rodentia dan Eulipotyphla, menunjukkan tingkat keanekaragaman dan endemisitas yang tinggi di wilayah Wallacea, terutama di Pulau Sulawesi. Meskipun sejumlah survei sebelumnya telah dilakukan, informasi mengenai distribusi dan keanekaragaman mamalia kecil di wilayah Semenanjung Utara Sulawesi masih sangat terbatas. Padahal, kawasan ini memiliki sejarah geologis yang kompleks dan merupakan habitat bagi berbagai spesies endemik, termasuk tikus dan cecurut. Penelitian ini bertujuan untuk menganalisis keanekaragaman dan distribusi mamalia kecil dari famili Muridae dan Soricidae pada empat lokasi di Semenanjung Utara Sulawesi, yaitu Gunung Dako, Gunung Galang, Ilomata (Taman Nasional Bogani Nani Wartabone), dan Gunung Klabat. Penelitian dilakukan pada rentang elevasi yang mencakup hutan dataran rendah, pegunungan bawah, dan pegunungan atas. Pengambilan sampel dilakukan melalui jalur transek menggunakan perangkap jepit, perangkap Sherman, dan pitfall trap. Spesimen yang diperoleh diukur secara morfologis, diidentifikasi, dan dianalisis keanekaragamannya dengan perangkat lunak PAST (Paleontological Statistics). Proses identifikasi mengacu pada standar internasional, dan seluruh spesimen diawetkan untuk kepentingan taksonomi lanjutan. Sebanyak 33 spesies mamalia kecil berhasil diidentifikasi, terdiri atas 23 spesies dari famili Muridae dan 10 spesies dari Soricidae. Pola sebaran spesies sangat bervariasi antar lokasi dan tipe habitat, dengan elevasi menengah (>1.000– 2.000 m dpl) menunjukkan tingkat keanekaragaman tertinggi, yaitu 29 spesies. Beberapa spesies memiliki sebaran luas (kosmopolitan), sementara lainnya bersifat lokal, yang mengindikasikan tingkat endemisme dan isolasi habitat yang tinggi. Indeks keanekaragaman Shannon-Wiener berkisar antara 2,00–2,57; nilai tertinggi ditemukan di Gunung Galang (2,57), sementara Ilomata menunjukkan dominansi oleh spesies tertentu. Hasil penelitian ini menunjukkan bahwa tingginya tingkat keanekaragaman dan endemisitas mamalia kecil di kawasan ini dipengaruhi oleh sejarah geologis Pulau Sulawesi yang unik, fragmentasi habitat, dan isolasi geografis. Temuan penting dari studi ini adalah adanya enam jenis mamalia kecil yang belum dapat diidentifikasi, yang diduga merupakan spesies baru. Hal ini menunjukkan bahwa Semenanjung Utara Sulawesi memiliki potensi besar untuk penemuan taksa baru, serta menegaskan pentingnya konservasi kawasan tersebut. Pola keanekaragaman yang teridentifikasi dipengaruhi oleh faktor elevasi, struktur habitat, dan adaptasi ekologis spesies terhadap lingkungan lokalnya.
dc.description.abstractNon-volant small mammals, particularly those belonging to the orders Rodentia and Eulipotyphla, exhibit high levels of diversity and endemism within the Wallacea region, especially on Sulawesi Island. Although several previous surveys have been conducted, information on the distribution and diversity of small mammals in the Northern Peninsula of Sulawesi remains limited. This region, however, has a complex geological history and is home to numerous endemic species, including rodents and shrews. This study aims to analyze the diversity and distribution of small mammals from the families Muridae and Soricidae across four sites in the Northern Peninsula of Sulawesi: Mount Dako, Mount Galang, Ilomata (Bogani Nani Wartabone National Park), and Mount Klabat. Sampling was conducted across different elevational ranges, encompassing lowland forest, lower montane forest, and upper montane forest. Specimens were collected using transect-based trapping methods, including snap traps, Sherman traps, and pitfall traps. All specimens were morphologically measured, taxonomically identified, and analyzed for diversity using the Paleontological Statistics (PAST) software. Species identification followed international standards, and specimens were preserved for further taxonomic research. A total of 33 small mammal species were identified, consisting of 23 species from the Muridae family and 10 from the Soricidae family. Species distribution varied considerably across sites and habitat types, with the mid-elevation zone (>1,000–2,000 m asl) exhibiting the highest diversity, comprising 29 species. Several species showed wide (cosmopolitan) distributions, while others were found only locally, indicating strong endemism and habitat isolation. The ShannonWiener diversity index ranged from 2.00 to 2.57, with Mount Galang showing the highest diversity (2.57) and Ilomata exhibiting dominance by certain species. These findings suggest that the high diversity and endemism of small mammals in the region are driven by Sulawesi’s unique geological history, habitat fragmentation, and geographic isolation. A notable discovery of this study is the presence of six unidentified species, which are suspected to be new to science. This highlights the Northern Peninsula of Sulawesi as a promising area for the discovery of new taxa and underscores the urgent need for conservation. The patterns of diversity observed were strongly influenced by elevation, habitat structure, and species-specific ecological adaptations to local environmental conditions.
