lisäänny

Lisäänny is a Finnish term used to describe the process by which the numbers of individuals, cells, or organisms increase. It is commonly used in biology, ecology, agriculture, and medicine to refer to reproduction or proliferation. The related verb lisäänntyä means to reproduce or multiply, and lisäännyminen (the noun form) refers to the act or process of reproduction or proliferation.

In biological contexts, lisäännyminen can refer to cellular proliferation, such as mitosis, or to organism reproduction, including both sexual and asexual modes. In population ecology, the term describes the growth of a population due to births and immigration, often measured as changes in population size over time. In horticulture and agriculture, lisäänny refers to propagation of plants and other organisms, encompassing methods that create new individuals, such as seed production or vegetative propagation, depending on the species.

The concept emphasizes numerical increase rather than the specific mechanism of reproduction. It is typically contrasted with terms describing decline or extinction. In scientific Finnish, more precise terminology may be used in particular contexts, but lisäänny serves as a general, everyday descriptor for growth through reproduction or proliferation.
