Kinabalu shrew range

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]

Distribution and habitat

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]

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.

<i>Nepenthes macrovulgaris</i> Tropical pitcher plant endemic to Borneo

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.

<i>Crocidura</i> Genus of mammals

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.

<span class="mw-page-title-main">Summit rat</span> Species of rodent

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.
