SPECIES

What is the main advantage of generalist species under changing environmental conditions?

“Adaptability to various habitats and food sources” for what is the main advantage of generalist species under changing environmental conditions. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. The inference is strongest when the relevant variables, spatial boundary, and time scale are explicit. Context can alter the magnitude of an effect without changing the definition of the focal concept. The remaining alternatives—“Highly specialized diet”, “Narrow niche occupation”, “Low reproductive rate”—r

Habitat Niche

Realized niche changes primarily due to:

“Interspecific interactions” for realized niche changes primarily due to. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Niche differentiation reduces overlap by separating species along resource, space, or time axes. Such partitioning can stabilize coexistence when each species performs relatively better under the conditions it uses most strongly. The remaining alternatives—“Genetic variation”, “Abiotic conditions alone”, “Population growth rate”—refer to different states, processes, or scales a
