Voltinisms

Part of speech: noun

Definitions

1. The number of generations an organism, especially an insect, completes in one year; a biological trait indicating reproductive frequency over a calendar period; a measure of lifecycle recurrence within a given time frame
2. A term describing how many times a species reproduces annually, particularly in entomology; an indicator of population renewal rates by year; the quantification of generational cycles per annum in living beings
3. The annual count of reproductive cycles an organism undergoes, notably insects; a classification of lifecycle speed based on yearly generation occurrence; a biological concept expressing frequency of generational turnover within a year

Etymology: "Voltinisms" is the plural of "voltinism," and the word is built from two parts: "voltine," a combining form from Latin "volta" (a turn, as in "revolution"), used in biology to mean "having a particular number of broods per year," as in "bivoltine" (two broods a year) and "univoltine" (one). The suffix "-ism" turns that into a noun for the condition or state, so "voltinism" names how many generations an organism produces in a year. The plural form simply refers to the different categories themselves: univoltinism, bivoltinism, multivoltinism and so on, each describing a distinct yearly rhythm of reproduction. Silkworm breeders and entomologists use the concept to classify insects by how quickly their generations turn over.

Synonyms: generations per year, broods per year
