"Noun"
/ˈjɪər klɑːs/
The term "year class" typically refers to a group of individuals (often animals or plants, such as fish in a body of water) that are born in the same year. It is used in fields like biology, ecology, and fisheries management to discuss populations and their dynamics. The phrase can denote the age structure within a population and is important for understanding breeding and survival rates.
In terms of frequency, "year class" is more commonly used in written contexts, particularly in scientific literature and research reports.
"The study focused on the growth patterns of the year class of salmon in the river."
(El estudio se centró en los patrones de crecimiento de la clase de años de salmón en el río.)
"Researchers observed significant differences between the year classes of the fish species in the lake."
(Los investigadores observaron diferencias significativas entre las clases de años de las especies de peces en el lago.)
"Assessing the year class of the deer population is crucial for effective wildlife management."
(Evaluar la clase de años de la población de ciervos es crucial para una gestión efectiva de la vida silvestre.)
The term "year class" does not have many common idiomatic expressions associated with it, as it is a specific term mostly relevant within academic or technical discussions. However, it can be linked to broader topics in ecology or population studies.
"The fishery has seen better days, especially with declining numbers in the 'year class' of 2020."
(La pesca ha visto mejores días, especialmente con el descenso de números en la 'clase de años' de 2020.)
"The 'year class' phenomenon plays a significant role in determining sustainable fishing practices."
(El fenómeno de la 'clase de años' juega un papel significativo en la determinación de prácticas de pesca sostenibles.)
"Understanding the 'year class' dynamics can make or break conservation efforts."
(Entender la dinámica de la 'clase de años' puede hacer o deshacer los esfuerzos de conservación.)
The term "year class" is derived from two English words: "year," which comes from Old English "geār," meaning a period of time or a calendar year, and "class," which is derived from Latin "classis," meaning a division or group. The combined meaning implies a classification based on the year of origin or birth.
