Lemmönkuljetus

Lemmönkuljetus, also known as lemmining or lemming transport, is a phenomenon observed in some species of lemmings, particularly the collared lemming (Dicrostonyx groenlandicus). This behavior is most notably exhibited during the summer months when lemmings migrate in large groups to new habitats, often over long distances. The primary motivation behind this mass movement is the need for food and suitable breeding grounds.

The migration typically begins when the lemmings' current habitat becomes overcrowded, leading to increased competition for resources. This overcrowding can be exacerbated by factors such as a sudden increase in the lemming population due to favorable breeding conditions or a decrease in predators. As a result, lemmings are driven to seek out new areas with abundant food sources and space for breeding.

The migration is characterized by lemmings moving in a coordinated manner, often in large, dense groups. This collective movement is thought to be influenced by a combination of factors, including the presence of suitable habitat, the density of the lemming population, and possibly even the influence of other lemmings. The exact mechanisms underlying this behavior are still a subject of scientific study.

Lemmönkuljetus is a remarkable example of animal behavior and has been the subject of numerous studies in ecology and ethology. Understanding this phenomenon can provide insights into the dynamics of animal populations and the factors that influence their movements and survival.
