Mule Deer
Most mule deer confine their daily movements to discrete home ranges which they use throughout the seasons in consecutive years.
Mule Deer
Because nutritious forage is in poor supply for much of the year, the mule deer has an annual cycle of metabolic rates, capitalizing on abundant, high-quality forage in the summer and surviving on a lower intake of poor-quality forage during the winter.
Mule Deer
All mule deer markings vary considerably among the species, but remain constant throughout the life of an individual.
Mule Deer
Female mule deer, related by maternal descent, form clans while males disperse as individuals or aggregate in groups of unrelated individuals, all maintained with dominance hierarchies.
Mule Deer
Ten subspecies of mule deer have been identified including two black-tailed deer subspecies and a hybrid subspecies of the mule deer and the white-tailed deer (Odocoileus virginianus).
Mule Deer
Mule deer are polygynous, having a tending-bond type breeding system, and mating within groups from late November through mid-December.

Mule Deer
The mule deer is endemic to North America and occurs in all of the continent's western biomes north of central Mexico, except the Arctic tundra.
Mule Deer
The manipulation of livestock grazing, cultivative communities, and vegetative communities can help manage habitats for mule deer, but these missions are often not compatible with bureaucracies.
Mule Deer
The mule deer is named for its ears, which are large like those of the mule and allow the deer's sense of hearing to be extremely acute.
Javan Rhinoceros
With such a small population of Javan rhinoceros left, the species' survival is threatened by low genetic diversity, the likelihood of inbreeding, and the potential of natural disasters.
Javan Rhinoceros
There are still major gaps in our knowledge about Javan rhinoceroses because they are extremely difficult to study and there's a remote possibility that remnant, undiscovered populations exist.
Javan Rhinoceros
The Javan rhinoceros is generally solitary, except for mating pairs and mothers with their young.
Javan Rhinoceros
There is little sexual dimorphism in the Javan rhinoceros, however females have shorter, less prominent horns or may lack a horn, entirely.
Javan Rhinoceros

Javan Rhinoceros
60% of Eastern Asian doctors stock rhino horn, with Asian horns, like that of the Javan rhinoceros, preferred over those of African species.
Javan Rhinoceros
The Javan rhinoceros has a unique, prehensile, pointed, upper lip that functions as an aid for feasting and grasping onto leaves.
Javan Rhinoceros
Although the Javan rhinoceros' habitat was once protected in Vietnam, it has now lost most of its forest habitat due to habitat loss, degredation, agricultural purposes, and other human activities.
Javan Rhinoceros
The Javan rhinoceros has poor eyesight, but keen senses of smell and hearing despite having smaller ears than other rhinoceroses.
Javan Rhinoceros
A young Javan rhinoceros will be active shortly after birth and will be suckled by its mother for 1-2 years.
Javan Rhinoceros
During colonial times, Javan rhinoceroses were killed by trophy hunters, but now, they're relentlessly poached for their horns and meat as rhino horn can sell for $60,000/kg.
Javan Rhinoceros
The Javan rhinoceros is threatened by the invasive Arenga palm, which is having a devastating impact on the plants the rhino relies on for food.
Javan Rhinoceros
The Javan rhinoceros population in Ujung Julon National Park has been increasing over the past 5 years and the feasibility of establishing a second population in another suitable, secure habitat is being considered.
Javan Rhinoceros
Although there's historically been 22 captive Javan rhinoceroses, none are currently captive and the species has never bred in captivity.
Javan Rhinoceros
Following the Vietnam war in 1975, the Javan rhinoceros was thought to be extinct in Vietnam, but was later spotted in the area in 1999.
Javan Rhinoceros
The Javan rhinoceros is a pure, herbivorous browser but was historically a mixed feeder, a more adaptable feeder than other rhinos.
Javan Rhinoceros
The Javan rhinoceros mates between July and November and females become sexually mature earlier than males.
Javan Rhinoceros
The Javan rhinoceros' scientific name, Rhinoceros sondaicus, comes from Greek and Latin referring to its horned nosed and locality in the Sunda islands of Indonesia.
Javan Rhinoceros
For decades, Javan rhino populations have hovered around 50 animals, the effective carrying capacity of the area which they reside, with an estimated 46-67 alive today.
