  • THE second order of mammals includes the Bats, or Chiroptera, literally hand-winged animals
  • As in the Primates, in which order the Bats were formerly included, there are four kinds of teeth, incisors, canines, premolars, and molars, the milk-set being followed by the permanent.

Vampire bats recognise their prey's breathing ( Vampire bats the only mammals to feed ...) - 0 views

  • Vampire bats, the only mammals to feed exclusively on blood, including human blood, recognize their prey by the sound of its breathing.
  • Vampire bats feed on the same prey over several nights
  • bats use breathing sounds to identify their prey in the same way as humans use voice to recognise each other.

Aerodynamics of Animals - Bats - Intermediate - 0 views

  • The bat is more closely related to primates.
  • Bats are fantastic fliers. They are able to truly fly. Bats are the only mammals able to have powered flight.
  • A bat's body is made for flight. The neck is short, the chest is large and the stomach is narrow. In order to fly a body must have a wide, thin surface. It also needs the power to push through the air.

  • The wings act like webbed hands. The bat can move its wings like we move our fingers. Bats fold one of their wings to steer and brake.
  • Many bats can hover in one place like hummingbirds and helicopters.
  • Bats live in barns, attics, and caves. They like anyplace that is cold and dark. They usually live in small groups. But their colony size can be in the 1,000's.
  • Tropical bats can transfer pollen as they fly from plant to plant. They digest bananas, mangoes, guavas, and berries in 20 minutes. The seeds of the fruit are dropped by the bats as they are flying. This reseeds large areas of land.
  • There are people who think that bats are dirty and evil. Bats are very clean and groom their wings and teeth daily. Some even believe that Count Dracula turns into a bat. This is not true. Bats are very helpful to man and our environment.

Bats In The Desert Southwest - 0 views

  • Bats are often thought of as flying mice,but they are more closely related to primates, including humans, than they are to mice.
  • the bat's body is covered by hair, with the exception of its wings.
  • Vampire bats don't suck blood. They make a small incision and lap up the blood of their hosts.
  • ...12 more annotations...
  • A bat will eat half its weight in insects in a single night.
  • Fewer people have died from bat rabies during the past 40 years than have died from dog bites or bee stings in a single year.
  • Although the bat is not blind, its eyes are best adapted to seeing in the dark, and see in only black-and-white.
  • The thumbs of the forefoot are small, equipped with sharp claws and not connected to the membrane.
  • Bats are very shy creatures and like most wild animals, avoid contact with humans while going about their business of eating, reproducing and avoiding predators.
  • When a bat returns to its roost for its upside-down sleep, it will spend as much as 30 minutes cleaning itself before settling down to sleep.
  • Some species of bats prefer to live alone in trees.
  • Nearly all bats that live in the United States feed on insects.
  • Mating may occur two or even three times a year
  • Bats have many natural enemies and large numbers of them die while still young.
  • The most significant causes of premature bat death, however, are the activities of people.
  • Bat droppings (guano) support entire ecosystems of unique organisms, including bacteria useful in detoxifying wastes, improving detergents and producing gasohol and antibiotics.

  • Cogito ergo sum (I think therefore I am)
  • reasoning and problem solving
  • deductive, inductive or abductive
  • ...19 more annotations...
  • Deductive reasoning involves deciding what must be true given the rules of logic
  • Inductive reasoning involves deciding what is likely
  • Deductive reasoning derives the logically necessary conclusion from the given premises.
  • it can lead to a logical conclusion which conflicts with our knowledge of the world
  • Human deduction is at its poorest when truth and validity clash
  • people bring their knowledge of the real world into the reasoning process
  • Induction is generalizing from cases we have seen to infer information about cases we haven't
  • In the absence of counter examples, all that we can do is gather evidence to support our inductive inference
  • Abduction reasons from a fact to the action that caused it
  • can lead to unreliability as an action preceding an event can be wrongly attributed as the cause of the event.
  • Problem solving is the process of finding a solution to an unfamiliar task
  • Gestalt theory and the problem space theory.
  • productive problem solving involves insight and restructuring of the problem
  • productive and reproductive
  • Reproductive problem solving draws on previous experiences
  • Reproductive problem solving could be a hindrance to finding a solution
  • theory says that problem solving centers around the problem space.
  • People solve novel problems by mapping knowledge in a similar known domain, to it
  • people miss analogous information unless it is semantically close to the problem domain.

      doesn't this basically say that humans are quite narrow minded, and fail to see a connection between two things unless it's right in front of them??

Green Countries - 0 views

  • China in particular has long argued that it is too poor to afford the Western luxury of environmental awareness.
  • China ranks last among 15 nations in its income group (the fifth decile), behind Vietnam. If Colombia, the group's leader, can afford environmental concern, why can't China?
  • China fares slightly better in protecting its habitat but much worse in measures of industrial ills.

  • One conclusion to be drawn from the Yale-Columbia project is the need for better data, which requires funds.
  • Experiences like the recent biofuels surge, which is driving up food prices, show how treacherous even well-intentioned decisions about the environment can be when they're uninformed.
  • The same holds for consumers, who sometimes think paying somebody to plant a few trees will compensate for flying around the world in airplanes.
  • For such decisions, data are essential. If we're going to avoid squandering our natural resources, the quicker we begin to rely more on facts and less on assumptions, the better.
  • Some countries simply lie or make up the facts.
  • Today's Russian bureaucrats may still be fudging its environmental figures.
  • Among the worst offenders were Japan, South Korea, Brazil, the United States, Italy and Paraguay.
  • (While there are good comparative data on ozone, smog also includes nitrogen oxides, carbon monoxides and other components that are poorly tracked in most nations.) Among the best industrial countries were Malaysia, the United Kingdom and all of Eastern Europe (a legacy of the Soviet nuclear program).

      desert nations how trouble with water supplies. Israel looks better than other nations.
  • Saudi Arabia, Egypt and the United Arab Emirates, which have more severe water problems.
  • Brazil is another country whose high rank—34th—is deceptive.
  • Brazil is a vast land blessed with an abundance of water, which yields energy relatively cheaply with no carbon emissions
  • Brazil is now the world's fourth biggest emitter of carbon, mainly due to the felling of trees.
  • By contrast, Belgium and the Netherlands, which share much in terms of population and geography with their neighbors, suffer from neglect of the environment—particularly in protecting native habitats.

beaches in the U.S - 0 views

  • Pollution at the nation’s 3,500 ocean, lake and bay beaches resulted in more than 25,000 closing or swimming advisory days last year, 28 percent more than in 2005, and the highest number in the 17 years that records have been kept, according to a new federal report released Tuesday.
  • he prime culprit was storm water runoff
  • Another 1,300 days were attributed to sewage spills and overflows.

  • could not be determined.
  • “Exposure to bacteria, viruses and parasites in contaminated beach water can cause a wide range of diseases, including ear, nose and eye infections; gastroenteritis; hepatitis; encephalitis; skin rashes; and respiratory illnesses,”
  • Most at risk are small children, pregnant women, cancer patients and others whose immune systems are weak or compromised.
  • “Children under the age of 9 had more reports of diarrhea and vomiting from exposure to waterborne parasites than any other age group,”
  • “found that more than 10 percent of swimmers report contracting gastroenteritis or respiratory infections after swimming. Based on those results and beach attendance numbers, nearly 300 people could expect to contract a respiratory illness after swimming in Lake Michigan in Chicago on a summer weekend.
  • “The study found skin rash and diarrhea to be consistently significantly elevated in swimmers compared to non-swimmers.
  • For diarrhea, this risk was strongest among children 5 to 12 years old,
  • an estimated 27 cases per 1,000 among children with any water contact, 32 cases among those with facial contact with the water, and 59 cases among those who swallowed water,
  • 92 beaches in 19 states as being “high risk”
  • 25 percent of tests.
  • “Aging and poorly-designed sewage and storm water systems hold much of the blame for beach water pollution. The problem was compounded by record rainfall, which added to the strain on already overloaded infrastructure.

Exxon Valdez - 0 views

  • It gained widespread infamy after the March 24, 1989 oil spill in which the tanker, captained by Joseph Hazelwood and bound for Long Beach, California, hit Prince William Sound's Bligh Reef and spilled an estimated 10.8 million US gallons (40.9 million liters) of crude oil.
  • This has been recorded as one of the largest spills in U.S. history and one of the largest ecological disasters.
  • At the time of the spill it was employed to transport crude oil from the Alyeska consortium's pipeline terminal in Valdez, Alaska, to the lower 48 states of the United States.
