Old World Monkeys - Cercopithecidae

Old World Monkeys - Cercopithecidae Old World monkeys (Cercopithecidae) are a group of simians native to Old World regions including Africa, India and Southeast Asia. There are 133 species of Old World monkeys. Members of this group include macaques, geunons, talapoins, lutungs, surilis, doucs, snub-nosed monkeys, proboscis monkey, and langurs. Old World monkeys are medium to large in size. Some species are arboreal while others are terrestrial. The largest of all Old World monkeys is the mandrill which can weigh as much as 110 pounds. The smallest Old World monkey is the talapoin which weighs about 3 pounds. Old World monkeys are generally stocky in build and have fore limbs that are in most species shorter than hind limbs. Their skull is heavily ridged and they have a long rostrum. Almost all species are active during the day (diurnal) and are varied in their social behaviors. Many Old World monkey species form small to medium sized groups with complex social structure. The fur of Old World monkeys is often gray or brown in color although a few species have bright markings or more colorful fur. The texture of the fur is not silky nor is it woolly. The palms of the hands and soles of the feet in Old World monkeys are naked. One distinguishing characteristic of Old World monkeys is that most species have tails. This distinguishes them from the apes, who do not have tails. Unlike New World monkeys, the tails of Old World monkeys are not prehensile. There are a number of other characteristics that distinguish Old World monkeys from New World monkeys. Old World monkeys are comparatively larger than the New World monkeys. They have nostrils that are positioned close together and have a downward facing nose. Old World monkeys have two premolars that have sharp cusps. They also have opposable thumbs (similar to the apes) and they have nails on all fingers and toes. New World monkeys have a falt nose (platyrrhine) and nostrils that are positioned far apart and open either side of the nose. They also have three premolars. New World monkeys have thumbs that are in line with their fingers and grip with a scissor-like motion. They do not have fingernails except for some species that have a nail on their largest toe. Reproduction: Old World monkeys have a gestation period of between five and seven months. Young are well developed when they are born and females usually give birth to a single offspring. Old World monkeys reach sexual maturity at about five years of age. The sexes often look quite different (sexual dimorphism). Diet: Most species of Old World monkeys are omnivores although plants form the larger portion of their diet. Some groups are almost entirely vegetarian, living on leaves, fruit and flowers. Old World monkeys also eat insects, terrestrial snails and small vertebrates. Classification: Old World monkeys are a group of primates. There are two subgroups of Old World monkeys, the Cercopithecinae and the Colobinae. The Cercopithecinae include primarily African species, such as mandrills, baboons, white-eyelid mangabeys, crested mangabeys, macaques, guenons, and talapoins. The Colobinae include mostly Asian species (although the group does include a few African species as well) such as black and white colobuses, red colobuses, langurs, lutungs, surilis doucs, and snub-nosed monkeys. Members of the Cercopithecinae have cheek pouches (also known as buccal sacs) that are used to store food. Since their diet is quite varied, Cercopithecinae have non-specialized molars and large incisors. They have simple stomachs. Many species of Cercopithecinae are terrestrial, although a few are arboreal. The facial muscles in Cercopithecinae are well developed and facial expressions are used to communicate social behavior. Members of the Colobinae are folivorous and lack cheek pouches. They have complex stomachs.

The Difference Between Public Relations and Journalism

The Difference Between Public Relations and Journalism To understand the difference between journalism and public relations, consider the following scenario. Imagine that your college announces it is raising tuition (something many colleges are doing due to drops in government funding). The public relations office issues a press release about the increase. What do you imagine that release will say? Well, if your college is like most, it will probably stress how modest the increase is, and how the school still remains very affordable. Itll probably also talk about how the hike was absolutely necessary for the face of continuing funding cuts, and so on. The release may even have a quote or two from the president of the college saying how much he/she regrets having to pass the ever-increasing cost of running the place on to students and how the raise was kept as modest as possible. All of this may be perfectly true. But who do you think wont be quoted in the college press release? Students, of course. The people who will be affected most by the hike are the very ones who wont have a say. Why not? Because of students likely to say the increase is a horrible idea and will only make it more difficult for them to take classes there. That perspective doesnt do the institution any favors. How Journalists Approach a Story So if youre a  reporter for the student newspaper assigned to write an article about the tuition hike, whom should you interview? Obviously, you should talk to the college president and any of the other officials involved. You should also talk to students because the story isnt complete without interviewing the people who are most affected by the action being taken. That goes for tuition increases, or factory layoffs, or for anyone else whos ever been hurt by the actions of a large institution. Thats called getting both sides of the story. And therein lies the difference between public relations and journalism. Public relations is designed to put the most positive spin on anything done by an institution like a college, a company or a government agency. Its designed to make the entity look as wonderful as possible, even if the action being taken - the tuition increase - is anything but. Why Journalists Are Important Journalism isnt about making institutions or individuals look good or bad. Its about portraying them in a realistic light, good, bad or otherwise. So if the college does something good - for instance, offering free tuition to local people who have been laid off - then your coverage should reflect that. Its important for journalists to question those in power because thats part of our primary mission: to serve as a kind of adversarial watchdog keeping an eye on the activities of the powerful, to try and ensure that they dont abuse that power. Unfortunately, in recent years public relations has become more powerful and ubiquitous even as newsrooms across the country have laid off thousands of reporters. So while there are more and more PR agents (reporters call them flacks) pushing positive spin, there are fewer and fewer journalists there to challenge them. But thats why its more important than ever that they do their jobs, and do them well. Its simple: We are here, to tell the truth.
