Islands far from mainland sources usually have:

“Low species richness” for islands far from mainland sources usually 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—“High species richness”, “Rapid colonization rates”, “Stable ecosystems”—refer to different states, processes, or scales and therefore do not express the same cau

Small islands far from the mainland typically have:

“Low species diversity” for small islands far from the mainland typically have. 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—“High species diversity”, “Moderate species diversity”, “No species”—refer to differen

Island Biogeography primarily studies:

“Distribution patterns of species” for island biogeography primarily studies. 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—“Evolution of species”, “Genetic diversity”, “Marine ecosystems”—refer to different stat

As species accumulate on an island, immigration rates generally:

“Decrease” for as species accumulate on an island, immigration rates generally. 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—“Increase”, “Remain constant”, “Fluctuate randomly”—refer to different states, process

Extinction Topic

According to data, introduced predators have caused about ______% of bird extinctions on islands.

“0.434” for according to data, introduced predators have caused about ______% of bird extinctions on islands.. 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—“0.254”, “0.38”, “0.51”—refer to different states, proc
