The patterns of seed dispersal are determined in large part by the specific dispersal mechanism, and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.
Wildebeest migrating in the Serengeti. Migration, in ecology, is the large-scale movement of members of a species to a different environment.Migration is a natural behavior and component of the life cycle of many species of mobile organisms, not limited to animals, though animal migration is the best known type.
The positive force of forest migration, plant population expansion, is governed by the seed dispersal capacity of the tree species' population and seedling establishment success. The population expansion limiting force, negative force, is the suppression by the environment of species' success in an area.
Sep. 30—Migration is as natural as hummingbirds flying south for the winter. "Migratory" pairs the migration of plants and animals with human movement for survival. Developed by Mexico City ...
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 ...
Assisted migration is a specific type of species introduction. Species introduction is any act of establishing a species in a habitat it does not currently occupy. It often refers to a long-distance relocation, such as the accidental introduction of an invasive species from one continent to another, or the intentional relocation of a species in decline to a habitat where it can persist.
Monarch butterflies are thought to respond to different cues that promote the fall season southern migration. These include the angle of light coming from the sun, the senescence of larval host milkweed plants, the decreasing day period and temperature drop. [21] The migration begins at the northernmost summer range approximately in August.
