| 説明 | Ankarana National Reserve, near Antsiranana, northern Madagascar.Canyon des Forestieres (near Camp des Americains).Madagascar is home to so many different plants and animals ... some of them endemic to the island and only found there.Sanford's brown lemur (Eulemur sanfordi), or Sanford's lemur, is a species of strepsirrhine primate in the family Lemuridae. Sanford's brown lemur was previously considered a subspecies of the common brown lemur (Eulemur fulvus) but was raised to full species in 2001. It is named after Leonard Cutler Sanford, a trustee of the American Museum of Natural History.This species is found at the very northernmost tip of Madagascar, ranging from Antsiranana to Ampanakana. Their populations are concentrated in a few forests – Ankarana, Analamerana and Montagne d'Ambre, with a small disjunct population in the Daraina region. The Manambato river is the southern limit of its range, although hybrids of the Sanford's brown lemur and white-fronted brown lemur appear to occur between Vohemar and Sambava. This species occurs in tropical moist, dry lowland and montane forests up to elevations of 1,400 m.In Ankarana it appears to favor secondary forest and is active at both day and night. Sanford's brown lemur is said to display a cathemeral activity pattern, becoming most active in the afternoon and evening with occasional bouts at night.Sanford's brown lemur is reported to associate with the crowned lemur during the wet season, a time of greater food availability. This friendly behavior would explain the occasional reports of hybrids between the two species.The diet of this species consists primarily of fruit, but includes other plant parts (buds, young leaves, flowers) according to seasonal availability, and also includes the occasional invertebrate (e.g., centipedes, millipedes and spiders). Consumption of insects is thought to be based on removing them rather than for nutrition. These biting invertebrates are a considerable pest and can be potentially harmful to them due to the toxic secretions. A millipede's defensive poison, exuded when a lemur bites or agitates the invertebrate, may be rubbed on the body in a behavior known as "millipede washing" in order to repel other biting insects (i.e. malaria-carrying mosquitoes).Sanford's brown lemur is considered to be Endangered, and among the rarest of the brown lemurs. Primary threats to its survival are habitat loss due to logging and mining, but hunting is starting to become a significant problem as well. |
