Study reveals four unique giraffe species across Africa

RESEARCHERS at the University of Copenhagen found evidence suggesting there may actually be four distinct giraffe species across Africa. This completely changes our understanding of giraffes. Recognising four giraffe species would mean developing separate plans to protect each one.

According to this article, Nubian giraffes are found in South Sudan and the Kordofan giraffe inhabits Cameroon, CAR, and possibly Sudan. Read more.

Study reveals four unique giraffe species across Africa

























Giraffes have long been admired for their beauty and stateliness. However, scientists have recently discovered a surprising fact about these animals: they may not be just one species.


Researchers at the University of Copenhagen found evidence suggesting there may actually be four distinct giraffe species across Africa. This completely changes our understanding of giraffes. Recognizing four giraffe species would mean developing separate plans to protect each one.


Four giraffe species

Previously, all the giraffes were recognized as one species – Giraffa camelopardalis. The research provided strong genetic evidence that all the giraffes are distinct enough to be classified as separate species.


Northern Giraffe (Giraffa camelopardalis)

All Northern Giraffes have lighter colored spots. They are divided into three subspecies, each found in different geographical locations:

  • Nubian giraffe: Found in Ethiopia and South Sudan.
  • West African giraffe: Located in Niger.
  • Kordofan giraffe: Inhabits Cameroon, Central African Republic, Chad, and possibly Sudan.

Reticulated Giraffe (Giraffa reticulata)

This species is also called the Somali giraffe, is known for its unique brown spots with clear white borders that look like a net. They live in northern Kenya, southern Ethiopia, and Somalia.


Masai Giraffe (Giraffa tippelskirchi)

Masai is the biggest and darkest colored of all, with patches shaped like stars that go all the way down to their hooves. You’ll find them in central and southern Kenya and throughout Tanzania.


Southern Giraffe (Giraffa giraffa)

Southern Giraffes have round or blotched spots, which are more uneven and less defined than the Reticulated Giraffe’s spots. They are classified further into two subspecies:

  • South African giraffe: Inhabits northern South Africa, southern Botswana, southern Zimbabwe, and southwestern Mozambique.
  • Angolan giraffe: Found in northern Namibia, southern Botswana, southwestern Zambia, and western Zimbabwe.

All of the groups are connected and some even mix, like the reticulated giraffe which has genes from both the northern and southern giraffe ancestors. The researchers were surprised by this interconnectedness.


“When we started getting results from our analyses of gene flow between different giraffe lineages, we had to check twice,” recalled Laura D. Bertola, a postdoc at the Department of Biology and one of the authors on the study.


Redefining giraffe species

This widespread mixing between giraffe groups throws a wrench into how we define a species. Traditionally, scientists thought extensive gene sharing only happened within a single species. But the giraffes’ story flips that idea on its head.


It suggests that the amount of genetic difference might not be the clear-cut way to identify new species as we once believed. “Our findings touch on a very delicate matter in biology, namely that we do not have a universally agreed species concept.” said Rasmus Heller, one of the senior authors.

Instead of trying to pinpoint the exact number of giraffe species, the study aims to highlight the fluidity of gene flow among giraffes, which remains possible under the right conditions.


Conservation of giraffe species

This discovery is a game-changer for giraffe species conservation. Traditionally, we’ve focused on protecting different species entirely. But this study emphasizes the need to consider the genetic variation within a species as well. Each giraffe lineage, regardless of its specific taxonomic classification, boasts a unique genetic makeup that deserves protection.


“Giraffes are such endlessly fascinating animals, and this study confirms just how much genetic variation there is even on small geographical scales,” noted Yoshan Moodley, a co-author of the study from the University of Venda in South Africa.


The findings from the University of Copenhagen are part of a broader effort under the African Wildlife Genomics research framework, associated with the African BioGenome Project.


The study is published in the journal Current Biology.

South Sudan: Mystery monkey: Rare red colobus caught on camera in South Sudan

Oustalet's or Semliki? That is the question. It may not be on everyone's lips, but it's uppermost in the minds of conservationists after a rare red colobus monkey triggered a camera trap several hundred miles outside its known range.

The image was captured in a remote forest in South Sudan as part of the extensive and ongoing camera-trap [ https://phys.org/tags/camera+trap/ ] surveys that began in 2015 as a collaboration between Fauna & Flora International (FFI), Bucknell University and the South Sudanese government.

Even for seasoned primatologists, Oustalet's red colobus—the Central African version of these acrobatic, fiery-coated monkeys—is a riddle, wrapped in a mystery inside an enigma. A remarkable 20 subspecies of this highly variable species have been described, according to The Kingdon Field Guide to African Mammals.

These include the version known to its close friends as the Semliki red colobus, named after the river valley in Central Africa where an isolated population was first recorded, and which may or may not turn out to be a separate species.

Identity crisis

While the experts are grappling with the complexities of colobus categorisation, there is no doubt that the monkey caught on camera represents a very exciting discovery, whatever the uncertainty surrounding which species or subspecies actually appears in the image.

Oustalet's red colobus—named in honour of a nineteenth-century French zoologist—is officially categorised as Vulnerable on the IUCN Red List, but is described as 'possibly extinct' in South Sudan, which lies at the extreme north-east of its range.

Most of the known populations elsewhere are widely scattered and typically confined to remote, seldom visited areas. This could explain why an apparently extinct monkey has remained undetected for so long before its cover was blown by a camera trap.

On the other hand, if—as the experts are speculating—the primate in the picture turns out to be the little-known Semliki red colobus, we have incontrovertible proof that this monkey occurs well beyond the previously accepted limits of its geographical range.

Either way, this is momentous stuff.

The latest photos, including the snapshot of the red colobus, are helping conservationists to compile an inventory of the previously undocumented species lurking in what is a relatively unexplored corner of Africa. The online citizen science platform, Zooniverse, is enabling the analysis of over half a million separate images captured by camera traps in this wildlife haven [ https://www.fauna-flora.org/news/south-sudan-latest-images-reveal-global-hotspot-biodiversity ].

Conservation in a conflict zone

FFI has been a constant presence in South Sudan for the past decade, despite the civil unrest that continues to blight the country. Focusing our efforts on the region of Western Equatoria, we are working closely with communities and government officials in order to build bridges, defuse conflict and secure commitment to a common conservation goal.

Decades of conflict have devastated lives and livelihoods—and wildlife—in what is now South Sudan. At the time of writing, a transition government has just been formed, sounding a note of hope for the future.

Mercifully, the biologically rich forested landscapes that lie within the 14% of the country that benefits from formal protection have remained largely unscathed. In particular, the band of dense tropical forest running along the border with the Democratic Republic of Congo in the south-west of the country harbours an exceptional range of species.

Its remarkable diversity is due largely to the fact that this tropical belt lies at the eastern edge of the Congo Basin, at the point where Central and East Africa's respective assemblages of animals and plants collide and coalesce.

It is also the only region in South Sudan where the red colobus occurs, along with nine—possibly ten—other primate species, including the endangered eastern chimpanzee.

Primates under pressure

Wildlife trafficking and the bushmeat trade, combined with poaching pressure resulting from food insecurity, are putting numerous species at risk.

There is an urgent need for further investigation into the extent to which the red colobus and other threatened primates are targeted for bushmeat. 

In the meantime, the combination of regular patrolling and camera trap footage will help FFI and partners to build a clearer picture of this monkey's distribution and likely population size.

The red colobus revelation is highly significant, but is by no means the only secret laid bare by the coordinated and comprehensive camera-trapping campaign. The protected areas [ https://phys.org/tags/protected+areas/ ] where the motion cameras have been deployed and where patrolling has focused are evidently vital strongholds not only for this red-listed red colobus and other primates, but also for African golden cats, forest elephants and a range of threatened antelopes including yellow-backed duiker and bongo.

South Sudan: images reveal global hotspot for biodiversity

South Sudan: latest images reveal a global hotspot for biodiversity
Report from Fauna & Flora International (FFI)
Written by Nathan Williams
Dated 16 August 2019

In 1979 the government of the Democratic Republic of Sudan and the government of Italy began working together to survey the incredible wildlife in the forests of Sudan’s Southern National Park in preparation for drawing up what they called a “Master Plan” for protecting the park.

Surveys undertaken over the following two years revealed a spectacular variety of animals, including elephants, pangolins, leopards, chimpanzees, monkeys, servals, hyenas and much more. With logging and hunting growing as threats, officials and researchers said, in an official report produced in 1981, that the protection of the park should be considered a “priority.” The stage seemed set for one of the world’s most biodiverse regions to secure the protection it deserved. 

But when civil war broke out soon afterwards, the plans were shelved. Conservationists left the country, government focus switched to fighting a war, and wildlife protection efforts were derailed for the best part of 30 years.

In recent years, despite the huge challenges, that has started to change. Fauna & FIora International (FFI) began working in South Sudan (when it was still part of Sudan) in 2010, and over the ensuing decade has built the trust and relationships essential to working in an environment still riven by civil conflict.

A significant development in FFI’s South Sudan work was reached when FFI and Bucknell University researchers teamed up with government authorities and local partners to deploy motion-sensing camera traps to record South Sudan’s still poorly understood wildlife.

Hundreds of thousands of images later, stunning pictures have emerged that shed light on the vast array of wildlife that inhabit these remote forests.

Through these images researchers have documented species not previously known to be found in this richly forested area, where the wildlife of East and Central Africa collide to form a unique tropical forest belt. From African golden cats to leopards, chimpanzees to aardvarks, the stunning images captured over the last year are evidence that this patch of Africa is home to some of the most varied wildlife on Earth.

The images are hosted on Zooniverse, the world’s largest platform for online citizen science; a collaborative project of the University of Oxford, Chicago’s Adler Planetarium, and the broader Citizen Science Alliance.

Community engagement

This region of South Sudan has historically fallen within a regional wildlife trafficking corridor from Central to North Africa, so to enforce laws and step up protection FFI and its partners have initiated patrols, involving local people and communities, focused on working within two reserves.

Delivering this protected area management and maintaining community led conservation efforts within community managed areas requires the Wildlife Service rangers and the communities adjacent to the Game Reserves to work closely together – cooperation that is unique to this area of South Sudan. The bridges that have been built between communities and government officials has created a pocket of stability and security which is enabling the continued build-up of on-the-ground efforts.

And these efforts are very much field-based. Despite the huge challenges of working in this region, FFI staff and its partners are not stuck in a compound but are out every day getting their hands dirty monitoring boundaries and conducting field work across a wide area of the landscape.

FFI’s approach also goes beyond dedicated species work and includes assisting communities with food security issues as well as equipping them with the tools for natural resource management. FFI’s goal is to see these communities become strong, long-term stewards of nature.

With civil strife a sadly regular feature of Sudanese life in recent years it would have been easy to pack up and declare South Sudan too difficult or dangerous to work in. Instead FFI has maintained a presence, adapting to situations and the reward is clear to see: some of the world’s most iconic species roaming the land they have called home for thousands of years, protected by a growing network of communities and conservationists.

S. Sudan works to protect wildlife

South Sudan tries to protect wildlife after long conflict

In this photo of Saturday March 16 2019, Rangers walk in a field near the Bire Kpatous game reserve along the Congolese border. South Sudan is trying to rebuild its vast national parks and game reserves following a five-year civil war that killed nearly 400,000 people. The conflict stripped the country of much wildlife but biodiversity remains rich with more than 300 mammal species, including 11 primates, but poaching is a growing threat. IMAGE 1 OF 12.

BIRE KPATOUS GAME RESERVE, South Sudan (AP) — Charles Matthew secures his beret, slings a rifle over his shoulder and prepares a team for an overnight foot patrol in Bire Kpatous, one of South Sudan's game reserves that survived the country's civil war but are now increasingly threatened by poachers and encroaching human settlements.

Matthew, 45, said he's proud of his work after years of being a soldier and has learned a lot about wildlife. "I didn't even know the names of species like aardvark, pangolin, crocodile and chimpanzee," he said of his knowledge when he started as a ranger 14 years ago.

But he worries about the reserve: "When poachers come and are well-armed, we can't get there in time."
South Sudan is trying to rebuild its six national parks and 13 game reserves, which cover more than 13% of the country's terrain, following the five-year civil war that ended last year after killing nearly 400,000 people. A fragile peace deal still has key steps to carry out.

The fighting stripped the country of much wildlife and the parks are rudimentary, lacking lodges, visitors' centers and roads. There is no significant tourism; the parks department does not even keep statistics on the number of visitors.

"Given these challenges, the biodiversity of South Sudan is in peril," said DeeAnn Reeder, a conservationist and professor at Bucknell University who has done research there. She called conservation efforts "significant but relatively small in scale given the vastness of the country" that still has the potential for surprise. The documentation of forest elephants in South Sudan was a "very significant find."

That biodiversity remains rich with more than 300 mammal species, including 11 primates. The country boasts one of Africa's greatest annual antelope migrations.

Now the biggest threat to the country's wildlife is poaching, the scourge that afflicts parks and reserves across Africa.

Bire Kpatous, near the Congo border and a convergence point for flora and fauna from Central and East Africa, has one of the region's "forgotten forests," as some conservationists call them. It is home to animals such as bongo antelopes, badger bats, African golden cats, forest elephants and forest buffalos.

The spread of unlicensed firearms, however, threatens to decimate wildlife while the resources to combat it are scarce. South Sudan's government allocated nearly $6 million for the parks and reserves last year, a figure considered woefully inadequate by some local authorities.

Western Equatoria state, where Bire Kpatous is located, has just one car for the 184 rangers overseeing three game reserves and one national park.

Some donors are stepping up. South Sudan last month received a pledge of $7.6 million from the United States Agency for International Development and another $1.5 million from the Wildlife Conservation Society to protect the parks.

Insecurity remains a challenge as unrest from the civil war continues. Western Equatoria state's national park, Southern Park, has been almost completely cut off from rangers' patrols since opposition fighters occupied parts of it in 2015, said Jonathan Nyari, former state director for wildlife services.
Bire Kpatous is also threatened by encroaching human settlements. Residents already burn swaths of land surrounding the park to clear it for cultivation. Rangers are working to foster support for the parks among local residents, who sometimes go out on patrol with rangers.

"Whenever we patrol the forest we sleep separately. In case we're attacked by poachers at least one person might survive," said Masimino Pasquale, a resident working with the rangers.

Residents say they often hear gunshots in the park but are without transport to investigate, said Samuel Apollo, the community's chief.

Another resident and wildlife advocate, Philip Michael, said he was threatened with death last year by people who blamed him for not "allowing them to kill animals."
The Britain-based Fauna & Flora International is teaching rangers and community members how to use a GPS, set camera traps and establish sustainable practices. The group also is trying to help South Sudan develop conservation tourism as an alternative source of revenue for a country whose economy is almost entirely dependent on oil.

While progress is slow, several rangers said they are seeing more signs of animals during patrols than they did last year.

Local teacher Isaac Pisiru said he wants to organize field trips to the park so his students will learn the importance of protecting animals.

"If I don't teach them about protecting animals, people will start destroying them," he said. "It's important for children to see animals physically and not just in books."
