Question

What are seasonal breeders?

Answer 1

Seasonal breeders are creatures that can only reproduce during a specific season of the year, whereas continuous breeders can reproduce all year.
Animal species that may reproduce or mate throughout the year are known as continuous breeders.
Males and females in continuous breeders are sexually responsive and capable of mating regardless of the season. Females in this category go through cyclic changes (menstrual cycle), but males can copulate at any time.

Complete answer:
Animal species that successfully mate at specific periods of the year are known as seasonal breeders. Due to factors such as the availability of food and water, the surrounding temperature, and changes in predation behaviour of other species, the survival of the young is enhanced during these times of the year.
Only when she is in season, or fertile and receptive to mating, do female seasonal breeders experience one or more estrus cycles. Male seasonal breeders, on the other hand, have fluctuating testosterone levels, test weight, and fertility depending on the time of year.
The hormonal influence on seasonal breeders affects when they will reproduce. This happens due to changes in hypothalamus secretion production, which triggers reproductive responses in both males and females.

Note:
Because of its involvement in hormone regulation, the hypothalamus is thought to be the central control for reproduction. These determinants influence when a seasonal breeder is ready to procreate.
The seasonal breeder is affected by the length of the day due to changes in melatonin secretion by the pineal gland, which then impacts GnRH release by the hypothalamus.
Gonadotropin-releasing hormone (GnRH) is a hormone that causes the anterior pituitary to release follicle-stimulating hormone (FSH) and luteinizing hormone (LH).
