Symposium Introduction

Komensalizm - nahlebnichestvo (from the Latin com - together, mensa - a meal). One form of symbiosis, a relationship in which one species receives benefit of cohabitation, and the other is indifferent. This unilateral use one species by another, without bringing him harm. Such, for example, relationship between lions and hyenas to match the remains of prey eaten by lions.

Fish-pilots escorted sharks, dolphins, flying with them in a layer water, directly adjacent to the body surface of these animals, and expending so much effort on such a speed and eating leftovers, faeces and parasites accompanied by animals. In bird nests, burrows rodents inhabit large number of arthropods, using microclimate Housing and living there at the expense of decaying food debris or other cohabitants. Many species do not occur outside the norm at all. Relationship type commensalism very important in nature, contributing to closer co-habitation species, a more complete development environment and use of food resources. Kvartirantstvo.

For some organisms, the body of animals of other species or their habitat (construction), provide a haven. Juvenile fish are hiding under umbrellas large jellyfish. In znezdah birds, rodents live in burrows of arthropods. Plants also use other species as habitats: the epitaph (algae, mosses, lichens). Woody plants serve as their place of attachment. They eat the same epitaphs from dying tissue, secretions and the host through photosynthesis.
