Natural selection will then result in more district plumage or songs of fruit eaters allowing them to be identified with other fruit eaters avoiding mating with seed eaters. Other individuals of the same seed eating ancestral species may find nectar as a viable source of food and evolve over time via natural selection into a new species. Adaptive radiation is when a single species evolves into a number of distinct yet closely related species. Each new species is adapted to live in a

Bats are flying mammals in the order Chiroptera (pronounced /kaɪˈrɒptərə/). The forelimbs of bats are webbed and developed as wings‚ making them the only mammals naturally capable of true and sustained flight. By contrast‚ other mammals said to fly‚ such as flying squirrels‚ gliding possums and colugos‚ glide rather than fly‚ and can only glide for short distances. Bats do not flap their entire forelimbs‚ as birds do‚ but instead flap their spread out digits‚[2] which are very long and covered with

bumble bee to attack predators multiple times. The workers also have a very important role in helping their hive by collecting pollen‚ which in the process helps the environment with the pollination of plants. The workers of the hive go out to collect nectar from flowers and feed themselves‚ and only produce enough honey to feed the young bees. Bumble bees can be found in northern regions and in higher altitudes than other bees because of their furry bodies and their unique ability to control their own

Honey bees has been considered a beneficial introduction; it distributes as a pollinator and the provider of the hive products. Some scientist has questioned the environment role of bees outside of their natural state or range. Majority of plant species are used by honey bees‚ which set some high potential disturbance for pollinator relationships. Honey bees do not necessarily harm plants: they are also unlikely to enlarge hybridization of native flora. Honey bees usually use a small proportion of

2001). Their populations are not permanent because to survive they need to be in relatively sunlit places that provide the appropriate host plants for protection and reproduction (Vandenbosch‚ 2003). They also need the proper plants that provide nectar for their consumption (Vandenbosch‚ 2003). At all life stages‚ Vanessa butterflies are incapable of surviving in cold temperatures (Vandenbosch‚ 2003). Due to this fact‚ Vanessa butterflies migrate (Stefansecu‚ 2001).
