Analysis of an evolutionary species–area relationship

  title={Analysis of an evolutionary species–area relationship},
  author={Jonathan B. Losos and Dolph Schluter},
Large islands typically have more species than comparable smaller islands. Ecological theories, the most influential being the equilibrium theory of island biogeography, explain the species–area relationship as the outcome of the effect of area on immigration and extinction rates. However, these theories do not apply to taxa on land masses, including continents and large islands, that generate most of their species in situ. In this case, species–area relationships should be driven by higher…

Island biogeography of the Anthropocene

As anole colonizations have increased, islands impoverished in native species have gained the most exotic species, the past influence of speciation on island biogeography has been obscured, and the species–area relationship has strengthened while the species-isolation relationship has weakened.

A generalized model of island biogeography

This model provides an ideal starting point for re-evaluating the role of speciation and re-analyzing available data on island species diversity, especially those biased by the MacArthur-Wilson model.

Speciation and endemism under the model of island biogeography.

It is concluded that, although the model leads to an apparent positive relationship between percentage endemism and species diversity on an island, this positive endemics-diversity relationship is not necessarily driven by speciation.

Species diversity can drive speciation

This work uses data for plants and arthropods of the volcanic archipelagos of the Canary and Hawaiian Islands to address whether there is a positive relationship between species diversity and rate of diversification and test the prediction that this increases with increasing species number.

A unified model of island biogeography sheds light on the zone of radiation.

It is argued that a paucity of data and theory on species abundances on isolated islands highlights the need for island biogeography to be reconnected with mainstream ecology.

A simple dynamic model explains the diversity of island birds worldwide

A global molecular phylogenetic dataset of birds on islands is compiled, based on the terrestrial avifaunas of 41 oceanic archipelagos worldwide, and a new analysis method is applied to estimate the sensitivity of island-specific rates of colonization, speciation and extinction to island features (area and isolation).

Ecological and evolutionary determinants of species richness and phylogenetic diversity for island snakes

Even large islands with high in situ diversification do not produce phylogenetically distinct faunas, but are instead dependent on colonization of new lineages from the continent, as predicted by ecological theory.

Ecology: Is speciation driven by species diversity?

It is suggested that species richness and endemism are correlated fortuitously owing to their mutual dependence on the life spans of populations on islands, which is unrelated to speciation itself.

Cichlid species-area relationships are shaped by adaptive radiations that scale with area.

It is shown that within-lake adaptive radiation strongly modifies the species-area relationship for African cichlid fishes, resulting in faunas orders of magnitude higher in species richness than fauna assembled by immigration alone.



Ecological and Evolutionary Determinants of the Species-Area Relation in Caribbean Anoline Lizards

Detailed examination of several components of evolutionary diversification indicates that the species-area relation among the Greater Antilles primarily results because larger islands have increased number of habitat niches occupied and a greater number of closely related species that are ecologically similar and allopatrically distributed.

The roles of island area per se and habitat diversity in the species-area relationships of four Lesser Antillean faunal groups

The results suggest that the four Lesser Antillean taxonomic groups diAer in their responses to area and habitat diversity are related to diAerences in several biological traits of the diAerent faunal groups.


The vicariance model proposes that the present biota rep- resents the fragmented remnants of an an- cient proto-Antillean biota that was con- tinuous with those of North and South America in the late Cretaceous.

Patterns of communities in the tropics

The following general hypothesis seems necessary:species interactions are important and the tropics have a head start on speciation, and the species diversity of the food supply nor the longer breeding season is relevant to bird species diversity.

Evidence for ecological speciation in sticklebacks is weakest, but there are several hints of its importance: speciation was rapid and accompanied by divergence into different ecological niches; selection against hybrids is stronger in the wild than in the laboratory, which suggests that hybrid fitness depends on ecological context.

Island biogeography in the Sea of Cortéz

The birth of this volume was a symposium on the same subject at the University of California, Los Angeles, in 1977. That this title has come along so many years later is a blessing, presumably to be

Ecology and Evolution of Communities

This chapter discusses the evolution of Species Abundance and Diversity in Communities Near Equilibrium and some Mechanisms Producing Structure in Natural Communities, as well as some mechanisms producing structure in natural communities.

Systematics of the Anolis roquet Series of the Southern Lesser Antilles

A phylogenetic analysis of approximately 1330 bases of mitochondrial DNA sequence for eight species of the Anolis roquet series reveals a single most parsimonious tree with strong support for seven internal branches, compared to earlier studies, which indicated neither the small-bodied nor the large-bodied species form monophyletic groups.

Phylogenetic Relationships and Tempo of Early Diversi cation in Anolis Lizards

— We examine phylogenetic relationships among anoles using mitochondrial DNA sequences from the NADH dehydrogenase subunit 2 gene (ND2) and Žve transfer-RNA genes representing 1,455 alignable base
