The Dinagat rat hedgehog ( Podogymnura aureospinula ) is one of the two species of the Philippines rat hedgehog within the hedgehog (Erinaceidae). It is endemic to the Philippines and inhabits the island of Dinagat , northern Mindanao and the nearby islands of Bucas Grande and Siargao .
features
The Dinagat rat hedgehog reaches a head-trunk length of 19.0 to 21.1 centimeters and a tail length of 5.9 to 7.3 centimeters. After the large rat hedgehog ( Echinosorex gymnura ) it is the second largest type of rat hedgehog. The back is covered by a bristly and thorny fur that is usually golden brown with black speckles. The ventral side is colored brown-gray. The ears are relatively large and covered with short white or dark brown hair.
Other typical features are the enlargement of the frontal region of the skull and tooth features.
distribution
The Dinagat rat hedgehog is endemic to the Philippines . Its distribution area is limited to Dinagat , the north of Mindanao and the nearby islands of Bucas Grande and Siargao .
Way of life
Very little information is available about the life of the Dinagat rat hedgehog. The species occurs mainly in the lowlands in primary forest , in secondary forest and in the forests known as " bonsai " forests with low-growing trees. On Bucas Grande, the species also lives in anthropogenically disturbed forests as well as in forest remnants in the vicinity of agricultural areas or even on the edge of heavily modified areas if forests are still nearby.
Systematics
The Dinagat rat hedgehog is one of the two species of the Philippines rat hedgehog ( Podogymnura ) within the hedgehog (Erinaceidae). Subspecies are not described. The second species is the Mindanao rat hedgehog ( Podogymnura truei ), which is mainly found in Mindanao. The first descriptors show that the classification into a separate, then monotypical , genus would also be justifiable due to the characteristics and differences to Podogymnura truei .
Hazard and protection
The species is on the International Union for Conservation of Nature and Natural Resources (IUCN) as endangered ( endangered listings). This is justified with the very limited distribution area of well below 5000 square kilometers as well as the progressive deforestation and habitat destruction on the Philippine islands. Dinagat is the only one of the islands with significant forest cover to have a mining concession for the extraction of mineral resources.
There is no information on the size of the world population, nor is there any data on population development. The species is relatively common in its primary and secondary forest habitat. How adaptable the Dinagat rat hedgehog reacts to changes in its habitat is unknown.
