This term is particularly relevant in the analysis of seasonal environmental changes and their influence on the physiology, behavior, and life cycles of organisms. Adaptations observed in response to these circannual rhythms include fur color transformation, molting , migration , breeding, fattening [ 1 ] and hibernation , all of which are ...
In elephants, the breeding season is less pronounced than in ungulates and it usually spikes when the rains season occurs or shortly thereafter. [28] [1] The rut is observed in both African and Asian elephants and it is referred to as musth. [29] Its meaning is derived from the Urdu word mast meaning intoxication. The most prominent ...
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds, mammals, fish, reptiles, amphibians, insects, and crustaceans. The cause of migration may be local climate, local availability ...
These interactions (whether it be plant-plant, animal-animal, predator-prey or plant-animal interactions) can be vital to the success and survival of populations and therefore species. Many species experience changes in life cycle development, migration or in some other process/behavior at different times in the season than previous patterns ...
Under regulation by gonadotropic hormones, ovarian follicles mature and estrogen secretions exert their biggest influence. The female then exhibits sexually receptive behavior, [12] a situation that may be signaled by visible physiologic changes. Estrus is commonly seen in the mammalian species, including some primates.
Seasonal breeders are animal species that successfully mate only during certain times of the year. These times of year allow for the optimization of survival of young due to factors such as ambient temperature, food and water availability, and changes in the predation behaviors of other species.

A lek is an aggregation of male animals gathered to engage in competitive displays and courtship rituals, known as lekking, to entice visiting females which are surveying prospective partners with which to mate. [1] It can also refer to a space used by displaying males to defend their own share of territory for the breeding season.
A behavior-oriented definition proposed is Migratory behavior is persistent and straightened-out movement affected by the animal's own locomotory exertions or by its active embarkation on a vehicle. It depends upon some temporary inhibition of station-keeping responses but promotes their eventual disinhibition and recurrence.
