The Kinabalu shrew (Crocidura baluensis) is a species in the family Soricidae. [1] [2] It is endemic to the mountain Mount Kinabalu on Borneo, and its sister peak, Mount Tambuyukon. [3] [4] [5]
Despite its resemblance in external morphology with the mountain shrew C. lepidura (Sumatra), multilocus phylogenies reveal a recent divergence of C. baluensis from the Sabahan lineage of the Bornean shrew, C. foetida sensu lato. The latter inhabits the lower slopes in Kinabalu, up to around 1500 masl, where it is replaced by C. baluensis. The larger size and longer hair of C. baluensis respect to the lowland C. foetida sensu lato seems related to adaptation to the colder mountain conditions. Future sampling at mid-elevations in Kinabalu will be required to address whether this closely related lowland lineage represents a distinct species or if Crocidura baluensis should be redefined to include these lowland Sabahan populations [6]
The Kinabalu shrew is native to Mount Kinabalu, where it inhabits montane rain forest (aka cloud forest) and higher-elevation subalpine shrublands and alpine meadows from 1,600 to 3,700 meters elevation. It is found in primary forests, degraded and secondary forests, and scrubland. [2]
It is also found in montane grasslands in the Kelabit Highlands above 1000 meters elevation. [2]
Mount Kinabalu is the highest mountain in Borneo and Malaysia. With an elevation of 4,095 metres (13,435 ft), it is third-highest peak of an island on Earth, and 20th most prominent mountain in the world by topographic prominence. The mountain is located in Ranau district, West Coast Division of Sabah, Malaysia. It is protected as Kinabalu Park, a World Heritage Site.
The white-toothed shrews or Crocidurinae are one of three subfamilies of the shrew family Soricidae.
The Bornean ferret badger, also known as Everett's ferret badger or the Kinabalu ferret badger, is a small, nocturnal and omnivorous mammal that is endemic to the island of Borneo. It is a member of the family Mustelidae and is one of six species of the genus Melogale. It is listed as endangered on the IUCN Red List of Threatened Species due to its small distribution range, which includes Kinabalu National Park and Crocker Range National Park.
Mount Tambuyukon or Tamboyukon is a mountain located at the West Coast Division of Sabah, Malaysia. It is considered the third-highest mountain in the country with height at 2,579 metres (8,461 ft), lying north of the highest Mount Kinabalu.
Nepenthes macrovulgaris, or the serpentine pitcher-plant, is a tropical pitcher plant endemic to Borneo. It is a lowland plant that typically grows at altitudes ranging from 300 to 1200 m in sub-montane forest clearings and mossy forest. Its range is restricted to ultramafic habitats, including Mount Kinabalu, Mount Tambuyukon, the Danum Valley, the Tawai Range, the Meliau Range and Mount Silam, all in Sabah, Malaysian Borneo. Pitchers grow to around 25 cm high and range in colour from green to brown, with the speckled form being the most common.
The genus Crocidura is one of nine genera of the shrew subfamily Crocidurinae. Members of the genus are commonly called white-toothed shrews or musk shrews, although both also apply to all of the species in the subfamily. With over 180 species, Crocidura contains the most species of any mammal genus. The name Crocidura means "woolly tail", because the tail of Crocidura species are covered in short hairs interspersed with longer ones.
Nepenthes ephippiata, or the saddle-leaved pitcher-plant, is a tropical pitcher plant endemic to Borneo. It occurs in the Hose Mountains of central Sarawak, as well as Mount Raya and Bukit Lesung in Kalimantan. It grows in montane forest from 1,000 to 1,900 meters elevation.
Nepenthes macrophylla, the large-leaved pitcher-plant, is a tropical pitcher plant known only from a very restrictive elevation on Mount Trusmadi in Sabah, Malaysian Borneo.
The summit rat is a species of rodent in the family Muridae. It is found only on Mount Kinabalu and Mount Tambuyukon, Malaysia, and has been recorded at altitudes of 2,040 to 2,477 m on Mt. Tambuyukon and 2,670 to 3,426 m on Mt. Kinabalu. They are most abundant in higher altitude dwarf forest and montane scrubland. The rat populations from these two peaks were connected in the Holocene. However, nowadays they are genetically isolated despite they are only 18 km apart. With current predictions of Global warming, the suitable habitat for Rattus baluensis is expected to shift around 500 m upwards. This will put the population in Mount Tambuyukon at risk. However, the population in Mount Kinabalu will likely survive in its upper slopes. Genetic analysis situate its origin in a local population of Rattus tiomanicus from northern Borneo at around 300-400 thousand years ago.
Kalophrynus baluensis is a species of frog in the family Microhylidae. It is endemic to Mount Kinabalu in Sabah.
The Bornean smooth-tailed treeshrew is a species of treeshrew in the family Tupaiidae. It is endemic to Borneo. Its natural habitat is subtropical or tropical dry forests. It is threatened by habitat loss.
The Sunda shrew is a species of mammal in the family Soricidae found in Indonesia and Malaysia.
The black-footed shrew is a species of mammal in the family Soricidae. It is endemic to northern and central Sulawesi, Indonesia where it lives on the floor of the tropical forests. The International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The Sulawesi white-handed shrew or Temboan shrew is a species of mammal in the family Soricidae. It is endemic to the island of Sulawesi in Indonesia. It is a fairly common species and the population seems stable so the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
Leptobrachella baluensis is a species of amphibian in the family Megophryidae. It is endemic to montane northern Borneo in Sabah and Sarawak (Malaysia) and northern Kalimantan (Indonesia). It has been in synonymy with Leptobrachella mjobergi, but is now treated as a valid species.
The Borneo montane rain forests is an ecoregion on the island of Borneo in Southeast Asia. It includes montane tropical and subtropical moist broadleaf forests, also known as a cloud forests. The ecoregion is partly in East Malaysia and Indonesia (Kalimantan).
The Bornean shrew is a species of mammal in the family Soricidae. It is found only on Borneo, throughout most of the island; it may or may not be present in Brunei.
The peninsular shrew is a species of mammal in the family Soricidae. It is found in the Malay Peninsula and Thailand. It is also found on the adjacent islands of Koh Samui, Pulau Tioman, and Pulau Mapor. This species has recently been synonymized with Crocidura malayana
