  2. Circannual cycle - Wikipedia

    en.wikipedia.org/wiki/Circannual_Cycle

    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 ...

  3. Animal migration - Wikipedia

    en.wikipedia.org/wiki/Animal_migration

    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 ...

  4. Rut (mammalian reproduction) - Wikipedia

    en.wikipedia.org/wiki/Rut_(mammalian_reproduction)

    Sparring is low-intensity aggressive behavior, involving mostly pushing and shoving. Bucks of different sizes will do this to each other. After pre-rut is finished, a buck will rub his antlers on a tree (thus making a "rub"), and make scrapes on the ground with his hooves: both of these are ways a buck will mark its territory and proclaim his ...

  5. Phenology - Wikipedia

    en.wikipedia.org/wiki/Phenology

    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 ...

  6. Seasonal breeder - Wikipedia

    en.wikipedia.org/wiki/Seasonal_breeder

    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. [1]

  7. Estrous cycle - Wikipedia

    en.wikipedia.org/wiki/Estrous_cycle

    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.

  8. Photoperiodism - Wikipedia

    en.wikipedia.org/wiki/Photoperiodism

    Daylength, and thus knowledge of the season of the year, is vital to many animals. A number of biological and behavioural changes are dependent on this knowledge. Together with temperature changes, photoperiod provokes changes in the color of fur and feathers, migration, entry into hibernation, sexual behaviour, and even the resizing of organs.

  9. Behavioral ecology - Wikipedia

    en.wikipedia.org/wiki/Behavioral_ecology

    Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
