Sandy asks…

What’s the fundamental and relized niche of a letherback sea turtle?

This is for honors biology. And i really need help figuring out what a niche is. also i need to find out if the leather-back sea turtle is a generalist or a specialist

New Niche Finder answers:

They are specialists, feeding on jellyfish. Very few animals can feed on jellyfish because of the stingers on them and because a jellyfish is mainly made up of water so there is little nutrition to be gained from eating one for most predators that do not specialize in eating them. The way the internal physiology works has to be a bit unique to derive nutrition from such a meal. With jellyfish numbers being kept in check the jellyfish don’t dominate the oceans and eat every small fish in sight.

Susan asks…

Interpret the finds with respect to the competitive exclusion principle and the ecological niche, and explain?

An ecologist visiting an island finds two very closely related species of birds, one of which has a slightly larger bill than the other. Interpret this finding with respect to the competitive exclusion principle and the ecological niche, and explain both concepts.

New Niche Finder answers:

Since both birds cannot co-exist on the same food, one has evolved, i.e. Those birds with slightly larger bills can eat seed the other birds can’t eat and thus occupies a new niche

William asks…

Are all niches within an ecosystem occupied?

Ecologists have argued about whether all niches within an ecosystem are occupied. Present examples that support both sides of the argument.

New Niche Finder answers:

All niches that support any life will have bacteria of some type. These will be the most varied life forms anywhere. For example, the gastrointestinal tract of any individual is a niche that is separated from similar niches in other individuals and other species. Yet, there are thousands of different species of bacteria in the GI tract of any individual. However, there are relatively few multicellular organisms, if any, that live in the GI tract of any given individual. The bottom line is that if it can be inhabited at all, it will first be colonized by bacteria.
