High biodiversity inhibits infection

Ecologists have shown that high biodiversity - the key to ecosystem health: the more species in it, the less they get sick.We know that biodiversity - is good, but often it is only the result of purely theoretical considerations. Obtain experimental evidence of the positive impact of biodiversity on ecosystem sometimes difficult. The reason for this - in the huge complexity of such research: biodiversity is best studied in large, complex ecosystems, and that means thousands and thousands of samples, and the mountain of statistical and analytical work. However, ecologists from the University Read more [...]

Phylogeny of the reproductive system

In lower animals (sponges, hydra) sex cells have no connection with any particular germ layers or body. These cells differentiate early and can be in any layer of the body. In the more highly organized animals (worms, arthropods, lancelet) not only exist heterosexual sex cells, but there are ways of their elimination. In vertebrates, there are all the elements of the reproductive system, but differ in structure. For example, amphibians, reptiles, birds, and urinary passages do not merge and develop two separate oviduct. This also explains the presence of two females in rodents, elephants, Read more [...]
