In these forests, winter is a time of dormancy for plants, [8] when broadleaf deciduous trees conserve energy and prevent water loss, and many animal species hibernate or migrate. [1] Preceding winter is fruit-bearing autumn, a time when leaves change color to various shades of red, yellow, and orange as chlorophyll breakdown gives rise to ...
[3] [4] Photoperiodic flowering plants are classified as long-day plants or short-day plants even though night is the critical factor because of the initial misunderstanding about daylight being the controlling factor. Along with long-day plants and short-day plants, there are plants that fall into a "dual-day length category".
Similarly, the western populations migrate annually from regions west of the Rocky Mountains to overwintering sites on the coast of California. Not all monarch populations make major migrations. Monarchs migrate short distances in Australia and New Zealand. There are some populations, for instance in Florida and the Caribbean, that do not ...

It occurs at elevations up to 1000 m (3200 ft). Adults migrate at night from upland habitats to aquatic breeding sites beginning with the first major rainfall of fall and winter, and return to upland habitats after breeding. Historically, the California tiger salamander probably occurred in grassland habitats throughout much of the state.
The Bogong moth is a native insect of Australia that is known to migrate to cooler climates. The Madagascan sunset moth (Chrysiridia rhipheus) has migrations of up to thousands of individuals, occurring between the eastern and western ranges of their host plant, when they become depleted or unsuitable for consumption.
The California Floristic Province is a world biodiversity hotspot as defined by Conservation International, due to an unusually high concentration of endemic plants: approximately 8,000 plant species in the geographic region, and over 3,400 taxa limited to the CFP proper, as well as having lost over 70% of its primary vegetation. A biodiversity ...
