New study: Flowers within the same species smells different in different places

to make a difference in variations within the same species, the researchers have named the different populations according to what they smell. A population smells like a pine forest, another like the chewing gum Jenka and another strong perfume.

the Discovery contributes with new pieces of the puzzle to ensure the conservation of species and smaller populations when the habitat is changing rapidly. The study shows that not only is to move on a species when it is in danger to die out because it probably will not thrive in a different environment.

– Flowers doftskillnader is genetic and does not depend on factors such as humidity, soil type or nutrient levels. We know this because the differences in fragrance is left when you pick them to a common greenhouse, and allow them to be together, " says Magne Friberg.

at the university of California and Sao Paulo and Cornell University has Magne Friberg during the eight years studied the scent of the flowers in the 94 populations of växtsläktet Lithophragma on the u.s. west coast.

That the flowers have different scents and thrive in different environments despite the fact that they are of the same species depends on the butterflies that pollinate.

– the Plants and butterflies have evolved together over a long period of time. Evolution has led to the flowers developed a unique scent in a small area, and that the butterflies in the same area, in turn, developed into local specialists who are attracted by the specific scent. Other floral scents, they feel not again.

have a threat to the butterflies detected. They are totally dependent on to find the flower that they are specialized on. They mate on the flower, drinking its nectar and lays eggs in the flowers. Find the butterflies not the flower they die.

– Why it is so, naturally, we shall look further at, but after eight years of studies we were required to report any of the results before we could proceed, " says Magne Friberg and continues:

– As an evolutionary biologist I am very curious and wonder why it is so, why have they small butterflies special preferences? As humans, we think very visually, in the form of color and form, but the insects live in a chemical world where scent is very important. It will be fun to watch in the world.

the large variation in the nature only true of the plant that researchers looked at in this study, they do not know yet but it is something they will investigate.

– Now we will start to look at Swedish and european plants. We already know that certain species always smells the same while the other may be differences in how and when they release their scent.
