Analyzing Interspecific Competition?


A hypothetical bat species (species 1) lives in a city. Another hypothetical bat species (species 2) established a population in the same city after a number of individuals escaped from a zoo. In isolation, each species prefers to roost in buildings that are three or more stories tall. After species 2 became established in the city, species 1 began roosting only in buildings less than three stories tall, whereas species 2 roosted in buildings three or more stories tall. Observers determined that the bright streetlights at ground level had previously deterred most bats from roosting in shorter buildings. Over many generations of existing in the same city with species 2, species 1 showed changes in eye size and retina structure. Complete the following statements about the two bat species. Drag the terms to the appropriate blanks to complete the sentences. Not all terms will be used. 1. Roosting areas in buildings of any height are the _______________ of species 1. 2. ____________ between the two bat species occurs because both species prefer the same roosting areas. 3. In parts of the city with only tall buildings (over two stories), ______________ of species 1 may occur. 4. Roosting areas in buildings that are one to tow stories tall are the ___________ of species 1 when species 2 is present. 5. The change in the roosting habits of species 1 after species 2 became established in the city is an example of ________. 6. The competition between the species for roosting areas is an example of a _______ interaction. 7. The changes in the eyes of species 1 are examples of ______. Answer choices: a.) resource partitioning b.) intraspecific competition c.) fundamental niche d.) interspecific competition. e.) realized niche f.) -/- g.) character displacement h.) competivie exclusion

How Do You Explain This Difference In Observed Yellow Swallow Habitats In Terms Of Niches And Interspecific Co?


Two species of closely related swallows live on the same continent. The black swallow lives in coniferous forests, and the yellow swallow lives in deciduous forests. On an island where the black swallow has never been introduced, the yellow swallow lives in both coniferous and deciduous forests. Explain this difference in observed yellow swallow habitats in terms of niches and interspecific competition.

Interspecific Competition — Mung Beans And Wheat?


1) For mung beans growing with wheat, is interspecific competition stronger or weaker than intraspecific competition? Is the same true of wheat?
2) Do mung beans and wheat seem to have substantial niche overlap, or do they occupy distinct niches? How can you tell from the de Wit diagram?
