CYCLOMORPHOSIS Meaning and
Definition
-
Cyclomorphosis refers to the phenotypic or morphological changes that organisms undergo in response to seasonal or environmental variations, particularly in aquatic ecosystems. This term is primarily used in the field of ecology and describes a specific type of phenotypic plasticity.
In cyclomorphosis, organisms exhibit variations in their body shape, size, color, or other morphological characteristics, which occur predictably and cyclically with changes in the environment. These changes allow the organisms to adapt to different ecological conditions and optimize their chances of survival and reproduction.
One of the most common examples of cyclomorphosis is observed in certain species of zooplankton, such as Daphnia. These small aquatic animals exhibit changes in their body shape and the presence of spines or other appendages in response to predation pressure. In the presence of predators, Daphnia develops elongated body shapes and longer spines, which enhance their ability to escape and reduce the likelihood of being captured. In the absence of predators, Daphnia morphs into a more rounded and less spiny form, which increases their feeding efficiency.
Cyclomorphosis is an essential adaptation strategy that allows organisms to respond rapidly to environmental changes without requiring genetic changes. By altering their morphology based on environmental cues, organisms are able to optimize their chances of survival and reproduction, thus enhancing their overall fitness in varying ecological conditions.
Etymology of CYCLOMORPHOSIS
The word "cyclomorphosis" is derived from two main roots: "cylo-" and "-morphosis".
1. "Cyclo-": This prefix comes from the Greek word "kyklos", meaning "circle" or "cycle". It is often used to indicate something related to a cycle or circular motion.
2. "-Morphosis": This suffix comes from the Greek word "morphosis", which is derived from "morphē" meaning "form" or "shape". It denotes a process of changing or transforming into a particular form.
Therefore, "cyclomorphosis" combines these roots to create a term that refers to the process of cyclic transformation or change in form or shape.
