Overview

Distribution

Range Description

Widespread in arid regions of North Africa (north of 17ºN) from Morocco and Mauritania to Egypt and Somalia, to along the northern fringes of the Sahara Desert. Also present across the Arabian Peninsula eastwards to Pakistan (68ºE) and north-west to Israel and Jordan. A recent record for Syria is the first confirmation of their presence in this country (Serra et al. in press). Suspected historical expansion of distribution area is likely due to desertification, compensated by competition with the red fox due to new human settlements. It seems to avoid the extreme arid regions in the middle of the Sahara, and the Arabian Empty Quarter, being more abundant on the fringes, in mountain massifs and near oases.

Physical Description

Morphology

Physical Description

Rueppell’s foxes are small foxes with a predominately sandy-colored coat. A gray color morph also occurs, apparently an adaptation for living in rockier areas. Much of this species' body plan reflects its adaptation to the harsh climate. Like many desert dwelling foxes, Rueppell’s foxes have large, broad ears, and feet with furred pads that protect them from the heated sand.

Vulpes rueppelli is slender and has a long, bushy tail with a white tip. The legs and muzzle are both short. The predominate color is “buff”, which is a sand-like color, but there are white hairs that make up the dense undercoat. Gray markings on the face are quite diagnostic of this fox. Although V. ruepellii is often confused with fennec foxes, fennec foxes are generally smaller than Rueppell’s foxes. Vulpes rueppellii, on average, achieves a body length of 40 to 52 cm with a tail length of 25 to 39 cm. At the shoulder, they reach 30 cm and they weight around 1.2 to 3.6 kg. Males tend to be slightly larger than females, but in other respects, the sexes are monomorphic.

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Their typical habitat includes sand and stone deserts. In Saudi Arabia, they have been found in open and stony habitats often with sparse vegetation cover, including a few herb and grass species (Fagonia indica, Indigofera spinosa, Tribulus spp., Stipagrostis spp. and Panicum turgidum) that receive little rainfall (~100 mm per year) (Lenain 2000). On the northern fringe of the Sahara, Rüppell's Fox may be found in similar areas with up to 150 mm annual rainfall. In Morocco (including Western Sahara), the general habitat presents sparse to very sparse vegetation cover, dominated by small brushes (Hammada scoparia, Panicum turgidum, Fagonia spp.) mostly concentrated in wadis (with Acacia spp., Argania spinosa, Balanites aegyptiaca, Maerua crassifolia and Capparis deciduas trees). In Niger (Dragesco-Joffé 1993) and Morocco (F. Cuzin, pers. obs.), the species avoids large sand dune areas, where the Fennec Fox is the only other reported canid species; however, in Algeria, they also occur in large ergs (De Smet 1988). In United Arab Emirates, Rüppell’s Foxes occur in a variety of desert habitats including sand sheets, sand dunes, gravel plains, and inter-dune sabkhas (Murdoch et al. 2007).

The Rüppell's Fox also lives in coastal areas, with extremely sparse vegetation and without any trees. They are able to survive in areas with little available water, as in central Saudi Arabia (Mahazat as-Sayd protected area) on the fringes of the Arabian Empty Quarter (Lindsay and Macdonald 1986; Murdoch et al. 2007), in Algeria (De Smet 1988) and in Western Sahara, where observations do not show any relationship with the distance to the nearest available water (F. Cuzin, unpubl.).

Rueppell’s foxes are highly adapted to their desert habitats. They inhabit a wide range of substrates, but are most common in areas with sandy or dry, stony desert substrate. Due to competition with red foxes, Rueppell’s foxes have been pushed to more extreme habitats that red foxes do not dominate.

Trophic Strategy

Food Habits

As with many desert predators, Rueppell’s foxes will eat almost anything that crosses their path. They are omnivores, partaking in anything from insects and small mammals to roots. Rueppell’s foxes tend to be mainly insectivores, but will chase and grab anything they can catch and eat.

Associations

Ecosystem Roles

Rueppell’s foxes serve as a population control for both rodents and insects. These pests can be very detrimental to humans considering both are important disease vectors as well as crop destroyers.

Predation

Due to the inhospitable habitat they occupy, Rueppell’s foxes have few predators. Their main predators are aerial predators such as steppe eagles and eagle owls. The fur of these animals is often closely matches the substrate, helping to conceal them from predators. Pups are hidden underground to further prevent predation.

Known Predators:

  • steppe eagles
  • eagle owls

Life History and Behavior

Behavior

Communication and Perception

As mentioned before, Rueppell’s foxes spend much of their time scent marking. They have a variety of scent glands, especially toward the anus. Foxes often sniff each other's anal glands in a greeting. This behavior is widespread within the family Canidae. Females mark their dens with their violet glands and are often sniffed by the male as he passes.

The type of communication that most dogs are known for is their ability to make some sort of barking noise. Rueppell’s foxes are no different, but only tend to use their bark or yelp when they are alarmed. When content, a fox tends to exhibit low chattering and long moans.

These animals have a well developed visual ability, and may use some visual communications, such as body postures, to communicate with conspecifics. Because they are social, tactile communication, especially between parents and offspring and between mates, is likely to be important also.

Life Expectancy

Lifespan/Longevity

Rueppell’s foxes have a lifespan in captivity of approximately 6.5 years to 12 years. Their lifespan in the wild is unknown, but is probably greatly shorter due to pressures such as predation and competition with red foxes. The maximum lifespan of these foxes in the wild has been estimated at approximately 6 years.

Reproduction

Like most canids, Rueppell’s foxes form monogamous pairs in the mating season. Little is known about the specific reproductive ecology of Rueppell’s foxes. There have been sightings of family groups, which may indicate the existence of an extended family, as has been observed in species like red foxes. In Oman, breeding pairs patrol a territory and usually den together. Cohabitation of the same den does not occur during the non-breeding season.

The process of attracting mates is not completely understood, but Rueppell’s foxes possess a vast array of scent glands. Male and female canids typically spend a great deal of time scent marking. Males may be able to sense heat through the vomeronasal organ. It is likely that Rueppell’s foxes are similar to other canids in these respects.

Mating System: monogamous

Rueppell’s foxes probably breed in winter, from November to January, considering related species such as fennec foxes and red foxes breed at this time. Females give birth to 2 or 3 helpless pups in March. Pups are blind at birth. The gestation period is thought to be around 50 days, similar to red foxes. Rueppell’s fox pups are thought to be completely weaned at 6 to 8 weeks. Pups are thought to become independent around the age of four months. They reach sexual maturity within the first year.

Breeding interval: Rueppell's foxes breed once yearly.

Breeding season: Breeding occurs from November to January .

Range number of offspring: 2 to 3.

Average number of offspring: 2.

Range gestation period: 50 (low) days.

Average gestation period: 50 days.

Range weaning age: 42 to 56 days.

Average time to independence: 4 months.

Average age at sexual or reproductive maturity (female): 1 years.

Average age at sexual or reproductive maturity (male): 1 years.

Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); fertilization ; viviparous

Average number of offspring: 2.

Many specific details on parental investment patterns of Rueppell’s foxes are unknown. However, the parents both serve important roles. In Oman, a female defends the den from her mate, but he remains in the area, never denning more than 200 meters away. A male may bring his mate food, like many other foxes do, or regurgitate food, a common practice in canids. Pups are independent after four months.

Parental Investment: altricial ; pre-fertilization (Protecting: Male, Female); pre-hatching/birth (Provisioning: Female, Protecting: Male, Female); pre-weaning/fledging (Provisioning: Male, Female, Protecting: Male, Female); pre-independence (Provisioning: Male, Female, Protecting: Male, Female); post-independence association with parents

Population

Population
Densities of Rüppell's Fox are usually low, but seem higher in areas where food is more freely available for example, near human settlements (Valverde 1957, K. De Smet, pers. obs.). In a large, fenced, protected area of 2,244 km² in Saudi Arabia, densities of 0.68/km² were recorded (Lenain 2000). Lower population estimates outside the fenced reserve indicate that the species may be vulnerable in the over-grazed, human-influenced landscape of central Arabia. In the reserve, the population is stable, but there is a need to document long-term population dynamics (Lenain 2000).

Threats

Major Threats
Threats include direct and indirect persecution by hunting and indiscriminate use of poisons. In Israel, the species is on the verge of extinction due to competitive exclusion by Red Foxes that are expanding their range following human settlements in the Negev Desert (Yom-Tov and Mendelssohn 1988), and competition with Red Fox is believed to be a problem elsewhere in the range. Rarely hunted for food or for sale of furs. However, in some regions, foxes face persecution for their perceived impact on game species like Houbara Bustard (Chlamydotis undulata) and livestock (Murdoch et al. 2007).

Management

Conservation Actions

Conservation Actions
Occurs in protected areas in Algeria, Egypt, Iran, Israel, Jordan, Libya, Mauritania, Niger, Oman, Saudi Arabia, Tunisia, and United Arab Emirates.

In Israel, the species is fully protected by law, and no hunting, trapping or trading is allowed. In Morocco, according to the annual hunting decree, Rüppell's foxes and red foxes may be hunted during the whole year, as they are considered as pests. In Arabia, no species-specific laws or regulations protect Rüppell's Foxes outside of protected areas. There is no information for other countries.

Rüppell's Foxes are held in captivity, including in the Rabat Zoo, Morocco; the Dubai Zoo, and the Breeding Centre for Endangered Arabian Wildlife in Sharjah, United Arab Emirates. Attempts to breed Rüppell's Foxes have generally not been very successful (Ginsberg and Macdonald 1990), although they have been successfully bred in the Hai Bar Breeding Centre, Eilat, Israel (E. Geffen pers. comm.).

Gaps in knowledge
The status and ecology of North African populations remains largely unknown. Monitoring of populations in well-established protected areas throughout the species' range is encouraged. There is scope for detailed study of competition between Rüppell's and red foxes.

Rüppell's fox

Rüppell's fox (Vulpes rueppellii), also spelled Rueppell's fox and also called the sand fox, is a species of fox living in North Africa and the Middle East, from Morocco and the Sahel region to the Afghanistan hills and SW Pakistan[1] It is named after the German collector Eduard Rüppell. Rüpell's fox is also called the sand fox, but this terminology is confusing because the corsac fox (Vulpes corsac) and the Tibetan sand fox (Vulpes ferrilata) are also known as the "sand fox".

It has an average life expectancy of up to 6 or 7 years in the wild, but can live much longer in captivity.

Description[edit]

Rüppell's fox is 40–52 centimeters (16–20 inches) long and has an average weight of 1.7 kilograms (3.7 pounds). It is a very small canine, and is considerably smaller than the red fox. It is sandy in color and has black patches on the muzzle, as well as a white tipped tail. Rüppell's fox has fur on the pads on its feet, that possibly helps distribute their weight and move easily on sand, and definitely keeps the hot sand from burning their feet. Similar to other desert dwelling foxes, Rüppell's fox has massive ears to cool it off. The tail is long and bushy. These features make Rüppell's fox look almost like a large fennec fox.

Behavior[edit]

Comparison between the skulls of a red fox (left) and a Rüppell's fox

Rüppell's fox relies on scent glands for many activities. It uses them to mark territories as well as to spray unwanted predators, similar to the behavior of the skunk. The female Rüppell's fox uses her scent glands to mark the cubbing den. Another use for the scent glands is that the foxes use them to greet each other. Rüppell's fox can bark, in a way similar to a dog.

Around mating season, Rüppell's fox travels in monogamous groups, or a male and a female, but after breeding season, the fox reportedly moves in family groups of 3-15 individuals. One animal occupies about 50-69 square kilometers of territory, though the male's territory is larger than that of the female's. Rüppell's fox is nocturnal and gregarious. The animals change dens often, and will abandon a den if there is a dangerous disturbance in the area. Most dens are dug under rocks, or under trees.

Rüppell's fox was pushed to living in the desert biome due to competition with its larger cousin, the red fox. It is known as being an extremely good survivor. Rüppell's fox's only predators are the Steppe Eagle and the Eagle Owl.

Diet[edit]

Rüppell's fox is a solitary forager. It is an omnivore, and will eat almost anything that crosses its path. Mostly, it is an insectivore, but its diet also consists of tubers and roots, as well as small mammals, reptiles, eggs, and arachnids.

Reproduction[edit]

The female Rüppell's fox has a gestation period of around 51–53 days. She has 2-3 kits, and each are born blind. They are weaned at 6–8 weeks of age. They are born underground, to protect them from predators.

Interaction with humans[edit]

For the past 100 years, Rüppell's fox has been treated like a pest. Rüppell's fox preys on many livestock animals in Arabia, including chickens, lambs, and young goats.

Conservation status[edit]

Rüppell's fox has no conservation status as of now, for it is too hard to estimate the actual numbers. As such, the IUCN lists them as Data Deficient.[2]

Subspecies[edit]

There are five subspecies of this fox:[1]

Rüppell's fox in philately[edit]

The Libyan Posts (General Posts and Telecommunications Company, GPTC) in cooperation with WWF (World Wide Fund for Nature), dedicated a postal stamps issue to Rüppell's fox on May 1, 2008. The issue is made of a set of four stamps printed in minisheet of two sets. The issue was completed with a special First day of issue Cover having a special postmark.[3]
