Charles Darwin For Kids
Charles Darwin For Kids
Some people have described Charles Darwin as the "father of modern biology". Whether this is true or not, is of course a matter of opinion, but it is certainly true that Darwin's idea, of evolution by natural selection, is one of (arguably the main) the key foundation stones of modern biological sciences.
The year 2009 marks the bicentennial anniversary of Charles Darwin's birth in 1809, and as a result there are currently many celebrations and commemorations of Darwin's life and work going on. Is however a great pity is that among the general public, although many people have heard of Charles Darwin and know that he has something to do with the theory of evolution, many do not know really know what his work was about.
Many people wrongly believe that the theory of evolution attempts to explain the origin of life, and that Darwin was the creator of this theory. Neither of these is true. The theory of evolution is not about how life first appeared (this is a different field of study known as "abiogenesis"), but rather is about how successive generations of organisms change over time. Additionally, Darwin was by no means the first person to propose an evolutionary theory, or even the transmutation of species (how one species evolves into another), but rather was responsible for providing a mechanism and an explanation (known as "natural selection") by which evolutionary processes work.
The main concept behind natural selection is actually surprisingly simple (although it does have complex and fascinating implications) - that organisms with heritable traits that are helpful to successful reproduction, will tend to predominate over organisms without such beneficial heritable traits, and thus, over successive generations, beneficial heritable traits will tend to become more common in any population. To explain this concept, Darwin used an analogy of selective breeding - pigeon breeders, over just a few centuries, have been able to produce a great variety of different domestic Pigeons by selecting for particular heritable traits - and similarly he argued that nature, over many millions of years, could produce a great variety of different organisms, by its own form of selection.
Among some religious people, Darwin's ideas, and even the idea of evolution, remains highly controversial. Among the scientific community, the principle of evolution, as well as related facts such as the great antiquity of the Earth, were already commonplace by Darwin's time. Darwin's theory of evolutionary (namely natural selection), however was for many years only one several competing evolutionary theories - it was only by the 1930s, when Darwin's ideas were combined with those of Gregor Mendel in what is known as the "modern synthesis", that it began to be recognized that natural selection was indeed the driving force behind evolution.

How to Stop Birds Eating Your Tomatoes
How to Stop Birds Eating Your Tomatoes
It is always fun to grow your own tomato plants, so when it is time to harvest, you pick the ripe fruits and prepare some marvelous delicacies with it. What is not fun is to put in so much hard work into growing your own tomatoes and then realizing that birds are enjoying it before you even get to them! If this has happened to you, then this information is right for you. You can try one or two tips mentioned below to keep these birds away so the fruits are eaten by their rightful owners.
Lightweight bird netting is one of the options you can use to keep these birds from reaching your fruits. However, make sure to consider one thing. Birds have sharp beaks and they can use it to poke at the netting if the openings are big. So, make sure to get very fine netting and just drape it over the tomato plants. You could use the stakes you planted for supporting your plant to protect it also. These stakes can be used to create a tent over the plant, however, make sure it reaches the ground so the birds cannot go under the plant and destroy your fruits.
Certain sound devices can be used to deter birds such as Pigeons and woodpeckers. Choose a sound device that varies in frequency, duration, and sequence. The device will be more effective if it features the sounds of both predators and birds in distress. These features in your bird repellant sound device will make sure they do not get used to one particular sound repeated over and over again and keep them away from your plants for good.
Some people hang red Christmas bulbs on the plants. How does that help? Well, birds think that these are tomatoes and peck at them but when they are not able to feed on these 'fake' tomatoes, they will give up and leave.
Shiny objects can also be used for keeping birds away. CDs or any other material that shines can be put all around your tomato garden to scare the birds. However, they can get used to these objects being there and after some time may realize they are not dangerous at all. So, keep moving them around so they think that they really are things that can hurt them.
Certain visual devices such as plastic owls or scarecrows can also protect your tomato plant. However, here you should keep moving it around, so the birds think that it is a real threat to their safety. Iridescent bird foil can be cut off into strips and placed on fence posts or tree tops. When these strips blow in the wind and catch sunlight, it changes colors and patterns along with producing a metallic rattle. So, it works both as a visual as well as a sound deterrent for the birds.
No one wants their tomatoes to be eaten up by birds before they are ripe. So, you can also harvest them before they are ripe and place them on a sunny window sill to ripen for 2-3 days. This way you get to save it from the birds and use it cook some delicious recipes.
So, if birds are eating up your tomatoes, its time to take some action. Use one of these tips and protect your precious fruits.

How to Get Rid of Cats From Your Property
How to Get Rid of Cats From Your Property
Getting rid of cats from your property can be very simple, you don't have to harm the cat, a one time effective treatment and the cat will never return again. Their are many products available to stop cats from entering your property, these include motion activated water sprinkler, if a cat hates anything more than a dog, it's water.
A dog is another obvious choice, unless you don't like dogs, then this may not an option. Dogs are the arch enemy to the cat, everyone in the world knows that once a cats being chased by a dog, it will never return to that area again.
Plants may not be an obvious choice as a cat repellent, but some plants like the Coleus Canina actually work as an effective barrier against cats. The Coleus Canina emits a foul smell thats cats don't like. This can work great, but unless you plant a lot of these over a large area, this choice of repellent can be inafective.
Lion Poo, is also supposed to work as an effective treatment. I know it sounds crazy, but this can actually work. Lots of Zoos will let you take this away for free, with some charging a very small amount of money. I suggest that this might be a last resort, it sounds very extreme, but in some cases where people have tried everything and nothing has worked, this might be their only chance of getting cats out of their property.
Their are many chemical products that can be purchased from many online retailers and local pet shops, this also maybe a last resort. If the cat is your neighbors, this might cause some friction between you and them, so please take caution when using any non natural products.

Racing Pigeon Feed - What You Should Be Adding To Your Pigeon Feed To Increase Their Speed
Racing Pigeon Feed - What You Should Be Adding To Your Pigeon Feed To Increase Their Speed
Water and Honey in Racing pigeon racing pigeon racing Pigeon Feed
Every fancier who wishes to keep up with the modern advances in racing pigeon feed, will make use of glucose-sugar. Glucose - the food for the muscles before the season and after the race, helps the birds to recuperate faster. If the birds are basketed on Friday, then on Wednesday and Thursday add 2 teaspoons full of glucose-sugar to each quart of drinking water. On their return from the race, for one day, add two or three teaspoons full of glucose-sugar to each quart of their drinking water every time your racing Pigeons feed. On the next day, clean the drinkers and serve fresh water. When we use tea, after it has cooled off, you may add some glucose-sugar to it.
Some fanciers use sugar cubes (6 to a quart of water), or crystal sugar, using one tablespoonful to a quart of water.
We prefer glucose as part of their racing pigeon feed because it is easier to use, and with us, it has given the best results.

Pigeon Nest Boxes - Simple Tips To Give Your Birds A Box They Will Love
Pigeon Nest Boxes - Simple Tips To Give Your Birds A Box They Will Love
Pigeon nest boxes have come about as a replica of how our Pigeons Loft.
However, if you want to make each of the pigeon nest boxes a separate unit, then you have the added advantage that they can be easily removed for cleaning and fumigation. Also, if you're tight on space, you can remove them and give your birds more room when they're not breeding.
Each of the pigeon nest boxes must be fitted with a suitable front that allows the birds some privacy, as well as allowing you get prevent other birds from entering and interfering with the pairing or the young birds.
It is recommended that you provide a small shelf, about seven or eight inches from the floor of the box, on which to place the nest bowl itself. This gives extra protection to the youngsters when they first leave the nest.
The number of nests in the loft depends on how many Pigeons Loft. It's best to return them to their nest box by hand each night for a week to ten days afterward, to be certain that they are well established. Allowing Pigeons to select their own boxes usually results in a great many fights, broken eggs, and injured youngsters.
Above all, pigeon nest boxes should be comfortable for your Pigeons, as the happier they are in them, the happier they will be to lay!
Carbohydrates and Racing Pigeons
Carbohydrates and Racing Pigeons
It's the time of year when we can light the stove in the evening again. That is the woodstove or the fireplace rather than the central heating system. Cozy, those dancing flames in the living room. In order the light the fireplace first I have to gather some kindling, kindling lights easily and burns quickly. Later we add bigger pieces of hardwood. Sometimes these big pieces of wood don't even fit in the stove. Reluctantly, I put on my coat to go outside and chop and cut these large pieces into smaller ones. When cut to the proper size the will fit into the stove.
Actually our bodies are a type of stove, which keeps us warm. The fire wood can be made up of carbohydrates, proteins, or fats. Above all, carbohydrates are fast acting fuels. They can be compared to the kindling we use to start the fireplace. Carbohydrates are sugars, which originate in large quantities in plants. They are produced during the process of photosynthesis. The bodies of humans or animals can only burn monosacharides. These occur in glucose (grape sugar), fructose (fruit sugar), ribose (sugar made up of 5 carbon atoms) and galactose (made up of glucose and part lactose).
Besides warmth these sugars also provide nourishment for the brain. Without this glucose syrup our beloved Pigeons Loft with three sections. Section 1was fed a normal breeding mix. Section 2 was fed 80% corn and 20% breeding mix. Section 3 was fed 80% peeled rice and peeled barley (pearl barley) + 20% breeding mix. The birds were all exercised together. The Pigeons Loft. The corn Pigeons fly much higher and the "rice and pearl barley" looked like dots in the sky. There were three layers of Pigeons flying at different heights. After half an hour to 45 minutes the "corn" pigeons were flying the highest.
When we switched the breeding mix section over to the "corn mix", we saw that after a few days they were the ones flying the highest after 45 minutes. We kept rotating the feed mixes between sections. The results were always as we have written above. From this we can conclude the following that the energy (fuel) provided by corn becomes available later then the energy out of white rice and peeled barley and that corn apparently is made up of more types of polysaccharides then white rice. Perhaps this explains, why pigeons that are to be sent to longer races, usually have extra corn added to their diets.
Glycogen
All these forms of sugar together are called glycogen. When energy is used in the stove the wood turns black and what is left over is called ash. When the bird uses energy the same type of process takes place. It is called phosphorylyse. The enzyme that catalyzes the phosphorylyse process breaks the Alfa - 1, 4 linkages down. These are the "Kindling" carbohydrates. For this process vitamin B6 is necessary. Glycogen is found in the liver and muscles.
During the races
During heavy exertion humans use up 60% carbohydrates, pigeons are different. The liver produces glycogen in order to keep the body warm. If we feed more glucose and glycogen then the daily needs of the pigeon, then the liver also can manufacture fatty acids from them. The blood transports these fatty acids to the red muscle fibers. A portion of the glycogen is transported by the blood to the white muscle fibers. A pigeon has approximately 15% white muscle fiber and 85% red muscle fiber. That is much more than a chicken that has practically all white muscle fiber. We can find many red muscle fibers in the breast of the pigeon.
If we make sure that just before the contest proportionally a high percentage of glucose is found in the glycogen then the fuel will burn faster. Also the liver will produce more fatty acids. This is the result of a makes sense.
Actually it only provides a small advantage on short races. After 10 minutes the fuel in the white muscle fiber in the breast is used up. The fuel stored in the white muscle fiber (glycogen) is used by the pigeon to reach flying height and speed. After this it uses the fast sugars "kindling" (Alfa- 1, 4 linkages) stored in the blood and liver are used. When the glucose is depleted then the enzymes process the Disaccharides and finally, the Polysaccharides are split and turned into monosacharides.
When "fast sugars" are all used up then the fatty acids that were built up by the excess sugars in the feed, which the liver turned into fatty acids become the fuel supply. Some of these are still present in the blood. They were on way to the red muscle fibers but had not yet been stored there. These will be used first.
After a short period of time the fatty acids stored in the red muscle fibers come into play. After 40 to 60 minutes of flying the pigeon is using the fatty acids stored in the red muscle fibers exclusively. Fats have the advantage of leaving little waste in the blood stream after being burned as fuel, although they burn slower than glycogen. The pigeon can fly fastest (wing beats per minute) on glycogen, but the fatty acids deliver more energy. Fats are 9.2 kilocalories per kilogram whereas carbohydrates are 4.0 kilocalories per kilogram.
The wood box
When the pigeon is using fats as its fuel and a bird of prey comes along then the pigeon will use any available glycogen (Alfa 1, 6 linkages) in order to quickly get away. These are what we could call "kindling" in the wood box. It is ready for use whenever we quickly need to light the stove again.
After the race
The pigeon uses firstly glucose and glycogen (the Alfa 1, 4 linkage), after that the fats. When the bird has used all its fatty acids then it will use any remaining glycogen (the Alfa 1, 6 linkages). When these are depleted then the pigeon will begin to use it "character". That is, it starts to use its own body; it burns its own muscles, the protein. There are many pigeons with little character. These will go down to rest and look for water and food. If they still come home it will be much too late. The "character birds" keep going. Burning protein or muscle is paired with muscle cramps and is very unpleasant for the pigeon. A pigeon that goes through this often will need weeks to recuperate.
Feeding carbohydrate rich food after a race is very important. The pigeon having used all its glycogen has a need to rapidly relight its stove

What Can I Do to Stop My Dog Biting Himself Until He Bleeds
What Can I Do to Stop My Dog Biting Himself Until He Bleeds
What can you do to stop your dog biting himself until he bleeds? The first step must be in finding out WHY he's doing this. And to examine all the possible sources, to put all your prejudices aside, all your preconceived ideas, and be completely open to the cause. If you are right, this will be borne out by startling improvements.
The first thing to accept is that your dog is itchy. But this itch has gone past the normal irritation stage, to self mutilation. So the itch has become intolerable.
Now for a quick diversion into the natural process of disease. When a body is overburdened by toxins, the safest way to eliminate them is through the skin. This means all manner of skin disorders can develop. Unsightly or irritating though they may be, they cause the least harm to the body.
So what could be the cause of your dog's toxic overload?
Primarily his food, but also any medication.
Most commercial dog food is made up of low grade meat (usually meat by-products), fat, cheap fillers and chemical additives. The chemical additives include colourants, appetite stimulants, isolated and synthetic 'nutrients' (in an attempt to address the poor nutrition) and preservatives, despite claims to the contrary.
By making a switch to a home-prepared quality, raw meat and bones diet, initially things may worsen. This rarely lasts more than a few days. It's an essential part of the process as it's a quick dumping of toxins.
Then things start to improve.
Your dog may still have a skin condition, but now he isn't so itchy, so doesn't constantly scratch and bite at himself. In time, the skin will improve and then the whole problem will be a thing of the past.
How much better is it to resolve the cause, than to simply mask up the effects?
And by using the powerful but gentle complete natural modality of health care, homeopathy, you can replace the need for toxic drugs for future health concerns.
