Potential Causes of Vacant Niches
Vacant niches could potentially have several causes.
• Radical disturbances in a habitat: For example, droughts or forest fires can destroy a flora and fauna partially or completely. However, in such cases species suitable for the habitat usually survive in the neighbourhood and colonize the vacated niches, leading to a relatively fast re-establishment of the original conditions.
• Radical and long-lasting changes in the environment: such as ice ages.
• Evolutionary contingencies: suitable species did not evolve for usually unknown reasons, or niche segregation between pre-existing species created a novel niche vacancy.

Famous quotes containing the words potential and/or vacant:
“Not many appreciate the ultimate power and potential usefulness of basic knowledge accumulated by obscure, unseen investigators who, in a lifetime of intensive study, may never see any practical use for their findings but who go on seeking answers to the unknown without thought of financial or practical gain.”
—Eugenie Clark (b. 1922)
“And ladies with their nails prepared for tea
And sunken barques that coast the shores of hell
And old men vacant of propriety
Have faintly rung a next-door neighbor’s bell.”
—Allen Tate (1899–1979)
