Tundra Vegetation Adaptations to Cold Environments 
Many tundra plants have adapted to flower and produce
seeds quickly once temperatures become favorable, ensuring their offspring have the best chance of survival
...Some tundra plants also exhibit
dormancy mechanisms that allow them to conserve energy during the long winter months
...
Seasonal Changes Fall is also a time of
seed dispersal, with many grassland plants producing seeds that will germinate in the following spring
...Many grassland plants enter a period of
dormancy, conserving energy until the warmer months return
...
Effects of Fire on Grassland Health Some of the positive effects of fire on grassland health include: Promotion of
seed germination: Fire can stimulate the germination of seeds by breaking seed
dormancy and providing a nutrient-rich environment for seedlings to grow
...
Role of Fire in Grassland Ecology Stimulating
seed germination: Many grassland plant species have evolved to rely on fire to trigger the germination of their seeds
...The heat and smoke from fires can break seed
dormancy and promote new growth
...
Effects of Fire on Grassland Ecosystems following table summarizes the effects of fire on grassland plants: Effect Description Stimulates
Seed Germination Fire can stimulate the germination of certain grassland plant species by breaking seed
dormancy and providing favorable conditions for growth
...
Desert Tactics survival tactics include: Tactic Description Estivation Some desert animals enter a state of
dormancy during the hottest and driest months to conserve energy and water
...Seed Dormancy Plants in deserts produce seeds that can remain dormant for years until conditions are favorable for germination
...
Ephemeral Plants in Deserts the extreme conditions of deserts by having short life cycles and being able to quickly germinate, grow, flower, and produce
seeds when water is available
...Some of the common adaptations include: Seed
Dormancy: Ephemeral plant seeds can remain dormant in the soil for extended periods until they receive enough moisture to germinate
...
Seasonal Variations Studied With increasing temperatures and longer daylight hours, plants start to emerge from
dormancy and undergo rapid growth
...Fall is also a critical time for
seed dispersal in grasslands, as many plant species produce seeds that will germinate in the following spring
...
Deciduous Forest Seasonal Changes Spring is a time of growth and reproduction, as plants flower and produce
seeds, and animals give birth to their young
...Many animals enter a state of
dormancy or hibernation to conserve energy during the cold months
...
Seasonal Variability in Tundra Ecosystem Health The seasonal variability in temperature and precipitation can affect the timing of plant growth, flowering, and
seed production
...growth, flowering Summer Rapid growth, seed production Fall Preparation for winter
dormancy Animal Adaptations and Migration Seasonal variability also affects animal populations in the tundra, influencing behaviors such as migration, hibernation, and reproduction
