Reticulated Giraffe Giraffa Camelopardalis Reticulata
Reticulated Giraffe Giraffa camelopardalis reticulata I’m Just Browsing… - Everything about a giraffe is longer or taller than other animals! Because of their height, giraffes do not have to compete for food. The giraffe’s legs are longer than an average man is tall (six feet), and their front legs are longer than their back legs. Even the giraffe’s tongue is long – as much as 18 inches. The tongue is strong and flexible allowing them to grasp and strip leaves from thorny branches. Pacing and Galloping - Because of their long legs, giraffe walk by moving both legs on one side of the body forward at the same time – a movement called pacing. When they run or gallop, their back legs are brought forward and ahead of their front legs. Giraffe can run up to 35 miles per hour over short distances. Classification One of nine described subspecies, all of which can easily interbreed. The closest living relative is the okapi. Class: Mammalia Order: Artiodactyla Family: Giraffidae Genus: Giraffa Species: camelopardalis Subspecies: reticulata Distribution Inhabits Eastern Africa and game reserves in South Africa. Habitat Dry savannah and open woodlands. Physical Description • Male giraffes are 16-18 feet (4.8-5.5 m) tall; females are 14-16 feet (4.2-4.8 m) tall. • Males can weigh up to 4,200 pounds (1,900 kg), and females weigh up to 2,600 pounds (1,180 kg). • Their coat has a regular box-like pattern of brown patches against a white background. • Their dark prehensile tongue is about 18 inches (45 cm) long. -
The Saola Or Spindlehorn Bovid Pseudoryx Nghetinhensis in Laos
ORYX VOL 29 NO 2 APRIL 1995 The saola or spindlehorn bovid Pseudoryx nghetinhensis in Laos George B. Schaller and Alan Rabinowitz In 1992 the discovery of a new bovid, Pseudoryx nghetinhensis, in Vietnam led to speculation that the species also occurred in adjacent parts of Laos. This paper describes a survey in January 1994, which confirmed the presence of P. ngethinhensis in Laos, although in low densities and with a patchy distribution. The paper also presents new information that helps clarify the phylogenetic position of the species. The low numbers and restricted range ofP. ngethinhensis mean that it must be regarded as Endangered. While some admirable moves have been made to protect the new bovid and its habitat, more needs to be done and the authors recommend further conservation action. Introduction area). Dung et al.

I Vividly Remember Reading About the Discovery of the Saola (Pseudoryx
I vividly remember reading about the discovery of the Saola (Pseudoryx nghetinhensis) in the BBC Wildlife Magazine whilst sitting in my traditional English school library. I was transfixed by the discovery of a distinctive, one-and-a-half-meter long, 70 kilogram ungulate with long tapered horns in the forests of Vietnam. I vowed there and then to work on and help the species however I could. Twenty-six years later I am still keeping that vow, but time is running out. It is going to take an incredible effort to stave off extinction and put the Saola on the path to recovery toward a fully functioning population. The discovery of the Saola in 1992 has been heralded as one of the most spectacular zoological discoveries of the 20th century, not only because of the size and beauty of the species, but also because of its phylogenetic distinctiveness; the Saola sits alone in a monotypic genus. Its morphological and genetic characteristics suggest it is a primitive member of the tribe Bovini, along with the cattle and buffalo, within the family Bovidae. The Saola is found in the North and Central Annamite Mountains of Vietnam and Laos where it is restricted to climatically wet evergreen, broadleaf forest habitats. These forests are subjected to an up to 10-month long rainy season, with no month receiving less than 40 mm of rain. This level of rainfall is the result of two monsoons, and determines the Saola’s distribution. The western and southern distribution of the Saola are bounded by the rain shadow of mountain chains with the western extent expanding deeper into Laos where the mountains dip, allowing deeper penetration of the northeast winter monsoon. -
Appetite for Destruction (Summary Report)
APPETITE FOR DESTRUCTION SUMMARY REPORT © RUDOLF SVEN 2 APPETITE FOR DESTRUCTION S ON / WW EXECUTIVE SUMMARY F Food is at the heart of many of the issues WWF focuses on. Through our work on sustainable diets, we know a lot of people are aware of the impact a meat-based diet has on water, land and habitats, and the implications of its associated greenhouse gas emissions. But few know the largest impact comes from the crop- based feed the animals eat. In a world where more and more people adopt a Western diet – one that’s high in meat, dairy and processed food – producing crops to feed our livestock is putting an enormous strain on our natural resources and is a driving force behind wide-scale biodiversity loss. The UK food supply alone is directly linked to the extinction of an estimated 33 species at home and abroad. WWF’s vision of a future where people and nature thrive is threatened by this current food system. This report looks at the impacts our appetite for animal protein – and in particular the associated hidden impacts of animal feed – has on our planet. We focus on the production of soy as feed for chicken, pork and fish and the consequences this has for the environment. We link the increased use of feed to the reduced nutritional value of these animal products, before exploring solutions through changing diets and alternative feed production systems.

Kenya Nairobi-amboseli-Samburu mount Kenya-Lake Nakuru- Lake Naivasha-masai mara 13 Days | African Charm & Close to Nature DAY 1 Destination: Arrival at Jomo Kenyatta International Airport; Transfer to Nairobi Accommodations: Ololo Safari Lodge Activities: Optional Game Drive Arrival at Jomo Kenyatta International Airport. After clearing customs, you will be met by your expert naturalist guide and transferred to the lovely Ololo Safari Lodge, an elegant, thatched-roof African manor situated right on the edge of the African wilderness, overlooking Nairobi National Park. Just outside of Nairobi’s central business district is Nairobi National Park, Kenya’s first national park established in 1946. This park is iconic for its wide open grass plains and scattered acacia bush with the city of Nairobi’s skyscrapers in the backdrop. Despite its small size and proximity to human civilization, this park plays host to a wide variety of wildlife including lions, leopards, cheetahs, hyenas, buffaloes, giraffes and diverse birdlife with over 400 species recorded. As well, it is home to one of Kenya’s most successful rhino sanctuaries, and you are likely to see the endangered black rhino here. After settling in, you will meet with your guide to briefly go over your safari itinerary. Enjoy a lovely lunch, featuring Ololo’s garden grown produce and eggs. You then have the option of going on a late afternoon game drive into Nairobi National Park or staying at the lodge, perhaps taking a dip in the pool, walking around the beautiful gardens, reading a book by the fire, or enjoying a drink on the terrace overlooking the park. -
