It occurs in plants and animals. Plant photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods. They are classified under three groups according to the photoperiods: short-day plants, long-day plants, and day-neutral plants.
[2] [3] [4] In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such ...
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 ...
Some animals that are nocturnal have disadvantages in animal sensory systems, such as bats, they have poor vision and use other adaptations such as echolocation, something a non-nocturnal animal would not have. Photoperiodism is the ability of plants and animals to use the length of day or night, resulting in the modification of their ...
During winter dormancy, plant metabolism comes to a virtual standstill, due in part to low temperatures that slow chemical activity. [1]Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped.
Tropical climates normally have only two seasons, a wet season and a dry season. Depending on the location of the region, the wet and dry seasons can have varying duration. Annual temperature changes in the tropics are small. Due to the high temperatures and abundant rainfall, much of the plant life grows throughout the year.
Alpine plants are one group expected to be highly susceptible to the impacts of climate change (Logan Pass, in Montana, United States). There is an ongoing decline in plant biodiversity, just like there is ongoing biodiversity loss for many other life forms. One of the causes for this decline is climate change.
When the wet season occurs during a warm season, or summer, precipitation falls mainly during the late afternoon and early evening. In the wet season, air quality improves, fresh water quality improves, and vegetation grows substantially, leading to crop yields late in the season. Rivers overflow their banks, and some animals retreat to higher ...
