Biogeography Complete

In the context of island biogeography, colonization refers specifically to:

“New species entering an island” for in the context of island biogeography, colonization refers specifically to. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Island biogeography explains species richness as a dynamic balance between immigration and extinction. Immigration generally declines as an island fills with species, whereas extinction rises as more species divide finite area and maintain smaller populations. The remaining alternatives—“Population decline”, “Species extinction”, “Genetic

Colonization primarily refers to:

“Immigration of new species” for colonization primarily refers to. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. At equilibrium, species identities can continue to turn over even when richness is approximately stable. The model predicts a balance of rates, not an absence of colonization or extinction. The remaining alternatives—“Emigration of existing species”, “Population growth”, “Speciation events”—refer to different states, processes, or scales and therefore do not express the same causal re

Colonization rates balanced by extinction rates:

“Over a long period of time” for colonization rates balanced by extinction rates. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Island biogeography explains species richness as a dynamic balance between immigration and extinction. Immigration generally declines as an island fills with species, whereas extinction rises as more species divide finite area and maintain smaller populations. The remaining alternatives—“Initially, then diverge”, “Only on large islands”, “Only on small islands”—refer to

Species turnover on islands is:

“Common and frequent” for species turnover on islands is. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Island biogeography explains species richness as a dynamic balance between immigration and extinction. Immigration generally declines as an island fills with species, whereas extinction rises as more species divide finite area and maintain smaller populations. The remaining alternatives—“Rare and infrequent”, “Nonexistent”, “Always decreasing”—refer to different states, processes, or scales an

Islands farther from mainland generally have:

“Lower immigration rates” for islands farther from mainland generally have. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. At equilibrium, species identities can continue to turn over even when richness is approximately stable. The model predicts a balance of rates, not an absence of colonization or extinction. The remaining alternatives—“Higher immigration rates”, “Lower extinction rates”, “Higher species richness”—refer to different states, processes, or scales and therefore do not express the

According to island biogeography theory, species number depends on:

“Colonization and extinction rates” for according to island biogeography theory, species number depends on. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Larger islands usually support more habitats and larger populations, lowering extinction risk; less isolated islands receive colonists more readily and may experience rescue effects. These mechanisms also apply to habitat fragments that function as ecological islands. The remaining alternatives—“Birth rate and death rate”, “Immigration and spec
