A. - Of all the 300+ shark species in the world, only about 30 have ever been reported to attack a human being. Of these, shark experts say about a dozen are particularly dangerous when encountered, and 3 especially, namely the Great White, Tiger and Bull Shark are mostly responsible for unprovoked attacks on humans. Since 1990, there are have been an average of 54 shark attacks a year worldwide, with an average of 21 of those (39%) along the Florida coastline.

Although the paleoanthropological record from some parts of the world suggest members of the hyaena family (eg., Pachycrocuta)once commonly preyed on humans (eg., on Peking man in China), this is no longer true and attacks on humans in the modern world are rare. Each year a very small number of Africans are mauled or killed by spotted hyenas in rural areas, most frequently when sleeping unprotected in the bush or moving about in the bush near dawn or dusk.

should also consult the ORCA/C bug list (see Q#9.2). As of mid-March 1998, there is an online bug tracking system for GNO. You can get to it off of the GNO Documentation Page. Its direct URL is: http://www.gno.org/~gno/bugs.html If you know of specific problems with GNO that are not listed in the database, please enter them. The web interface is the preferred method of submitting reports, but if that is not feasible you can also send bug reports to the following address: gno-bugs@trenco.gno.

Ellipsis has a wide variety of clients interested in numerous plant and animal species. We have experience in genotyping projects for medical research, non-medical human applications, agriculture and the food industry.

If humans lived at the same times as dinosaurs it is likely that some of the larger carnivorous dinosaurs would try to eat them, in the same way that lions or tigers sometimes try to eat humans today. But, humans have only been around for the last 1.5 million years, and dinosaurs died out about 65 million years ago! Evolution is caused by a change in an animal's environment selecting one type of animal instead of another.

Adding fish Q12a. It is my belief that to add new Tropheus to a colony, one needs to introduce young uncoloured fish, which pose no threat to the order of things with the other fish.

I would not like to generalise about which species is the more aggressive, just depends on the luck of your colony make up. As for controlling aggression - the bigger the colony the easier it is. back to list of questions No. when you work it out let me know - I am sick of lugging rock! I put a tank divider in and then just take out the rock on the side where the fish is. I have never had any luck catching Tropheus with a torch when they are sleeping in a heavily rocked tank.

There is no evidence to date that cats can spread H5N1 to humans. No cases of avian influenza in humans have been linked to exposure to sick cats, and no outbreaks among populations of cats have been reported. All of the influenza A (H5N1) infections in cats reported to date appear to have been associated with outbreaks in domestic or wild birds and acquired through ingestion of raw infected meat.

Attacks on humans are remarkably rare events but when they happen, they inevitably get the attention of the national news media. No one, however, can answer why bears "attack" any more than they can answer why humans attack other humans. Bears can attack for any number of reasons simply because they are wild and unpredictable creatures. A bear's natural reaction is to avoid humans.

No, mosquitoes infected with the virus can transmit it through a bite to birds, horses, and other mammals, (crows, squirrels, sheep, ducks and chickens).

We have only had one (1) report over the years of someone having to use their OMEGA on a mean, aggressive dog. This person reported that a "pit bull" would not let them out of their home through the front door, so they sprayed the dog with OMEGA. As a result, the dog ran away immediately with it's tail between it's legs and hid under someone else's porch. Yes.

Education and experience will be the best line of defense. The employee who has been in field for any amount of time has confronted thousands of dogs and now has learned to read the dogs movements and temperament. The experienced employee has learned to use what is around him to safely get out of the yard or get to the vehicle. As far as what to carry, overwhelming we are told that most employees want to carry either the Dog Stick (Wand) or the Umbrella.

One's own body cells have proteins that are antigens (these include a group of antigens called HLA antigens). The immune system learns to see these antigens as "normal" and does not usually react against them.

No. We will not be able to care for aggressive pets. As the owner you are responsible to disclose whether your pet has ever bitten anyone in the past. If so, we must take our own safety, and the safety of others into consideration, and we would have to decline the job.

A: A group of 10 sequences is reserved for each "base" anything, and it's always a multiple of 10. If you want to add a creature that walks around with sequences 601, 603, 607, and 609, then the BASE WALK should be set to 600. If you want to add a creature that attacks with sequences 531, 533, 537, and 539, then the BASE ATTACK would be 530. Basically, the "base" gives a quick number to use by simply adding the direction. If facing right (direction 6) then 530 + 6 = 536.

lt;Yes, but less so than you average Trigger. They need tankmates that can hold their own in an aggressive predator tank, and should probably be one of the last fish added.>

A.- There was only one way to do that, of course. So he rolled up his sleeve and injected into his own bloodstream. Just as predicted, there were absolutely no harmful or distressing side effects.

A.: There are several Italian and international medical studies that have shown evidence for health damages caused by an excessive exposure of the employees to vibration. Vibration can cause different health problems, which can be for instance digestive problems, circulatory problems, reproductive problems or back problems.

Speciation in primates, from commencement of prezygotic isolation to full postzygotic isolation, has taken between 1 and 4 million years to occur, considering pairs of living primate sister taxa (Curnoe et al. 2006). Mitochondrial DNA suggests that modern humans and Neandertals derived from a single ancestral population at most 250,000 - 500,000 years ago (the population divergence time consistent with a 350,000 - 700,000 year genetic divergence).

The deer tick (Ixodes scapularis) in the eastern United States and its close relative the Western black-legged tick (Ixodes pacificus) on the Pacific Coast are the only tick species currently known to transmit the Lyme disease spirochete (a type of bacterium) to humans. Other tick species have been observed to harbor the spirochete but apparently cannot transmit it to their human hosts.

A: See the "Species Marked" page--last we heard, that was the list. Every time we think we've heard it all, someone tries it on something new!

About one in five people infected by the virus develop West Nile fever, a typically mild illness that causes fever, muscle aches, fatigue, headache and joint pain. These persons recover fully and do not require hospital care. A smaller number of infected persons, 1%, develop encephalitis or meningitis with symptoms of high fever, neck stiffness, confusion, disorientation, coma, tremors, convulsions, muscle weakness, and paralysis.

Avian flu currently poses only a small danger, as the virus does not normally infect animals other than birds or pigs. However, human beings have been infected in Vietnam, Thailand, Cambodia, and Indonesia, although these cases were linked to direct contact with dead or diseased poultry. One case of human-human contact was suspected in Thailand in 2004. There is no vaccine to prevent H5N1 infection in human beings, although there are drugs to treat the illness.

The Baikal world is extremely diverse. Now Baikal is known to have 1550 species and varieties of animals and 1085 species of plant organisms.

A - Saliva, Sweat, Tears, and Urine do not transmit HIV - But, semen, blood, and vaginal fluids do. Any activity that includes no direct contact with your partner’s semen, blood or vaginal fluids is safe. Activities that do involve direct contact with semen, blood, or vaginal fluids are risky. Any precautions that reduce the chance of direct contact with those fluids will make sex safer. A - Yes. That is why we have the term Safer Sex.

I wrote about that question last year, concluding: There will never be any tidy solution to the species problem, because all species have unique evolutionary histories and constraints. Given these difficulties, the species status of archaic Homo populations is basically an intractable problem. That is, I am happy to suggest that archaic Homo populations correspond to classical subspecies, and as far as I know, no evidence strongly contradicts that position.

No. Because species differ anatomically, physiologically, metabolically and psychologically from one another, each species responds to chemicals and drugs differently. Chemicals that are toxic to some species aren't toxic to others, and no species is an infallible model or predictor for another. As a result, many products that have proven to be harmful to humans did not harm the non-human animals on whom they were tested.

In most resort areas the vendors have stalls set up outside of the resort property. Most hotels don't allow vendors to approach tourists on the beach. You have to go to them, then you're fair game. Each one will tell you he has the "best prices". Of course, the first price he quotes you will be twice what it's worth - you have to bargain, it is expected. If you're not into bargaining, stick to the hotel gift shops.

We see remarkably little “acting out”. Our open setting, a commitment to social responsibility, and use of therapeutic relationships help our members develop mutual support and self-restraint. If severe threats, violence, or active substance abuse occur in spite of everyone’s best efforts, we may utilize a brief psychiatric hospitalization. There also may be situations when, as a reality-based consequence, we consider a local law enforcement response.
