Since the recognition that allopatric speciation can be induced by large-scale reconfigurations of the landscape that isolate formerly continuous populations, such as the separation of continents by plate tectonics, the uplift of mountains or the formation of large rivers, landscape change has been viewed as a primary driver of biological diversification. [] Key Result Instead, the strongest predictors of speciation are the amount of time a lineage has persisted in the landscape and the ability of birds to…

Climate, habitat associations and the potential distributions of Neotropical birds: Implications for diversification across the Andes

Contrary to the long-held view that the uplift of the Andes spurred biotic diversification by causing vicariance across multiple lineages with formerly continuous distributions, recent work suggests

Moving beyond the riverine barrier vicariant paradigm

These findings argue against the role of the Paraná‐Paraguay river system as a major biogeographic barrier and highlight the need to explore the roleOf ecology in species diversification, a basic protocol to advance the study of riverine barriers is suggested.

Renewed diversification following Miocene landscape turnover in a Neotropical butterfly radiation

One of the most comprehensive time-calibrated molecular phylogenies of a group of Neotropical insects: the butterfly tribe Ithomiini is generated, finding that Istomiini likely began diversifying at the interface between the Andes and the Amazonia around 26.4 my ago.

Geography and past climate changes have shaped the evolution of a widespread lizard from the Chilean hotspot.

The dual role of Amazonian rivers in the generation and maintenance of avian diversity

The data provide compelling evidence that species turnover across the Rio Negro basin encompasses a mixture of histories, supporting a dual role for Amazonian rivers in the generation and maintenance of biological diversity.

Evaluating the contribution of dispersal to community structure in Neotropical passerine birds

For two centuries evolutionary biologists have sought to explain elevated biodiversity in the Neotropics. Although different process are known to be important, it is still not uncommon for

Diversification across biomes in a continental lizard radiation

Rock‐dwelling and generalist taxa differ morphologically, but only the lineage‐poor central AAZ taxa have accelerated evolution, which suggests environmental heterogeneity and refugial dynamics have been more important than ecological release in elevating lineage diversity.

Speciation with gene flow in whiptail lizards from a Neotropical xeric biome

The results revealed a striking complex diversification pattern where the Northeast lineage originated as a founder effect from a few individuals located along the edge of the Southwest lineage that eventually expanded throughout the Caatinga.

Biogeographic regions and events of isolation and diversification of the endemic biota of the tropical Andes

Significance This study unifies quantitative methods with dated molecular phylogenies of different lineages to identify biogeographical regions and understand the spatial and temporal evolution of

Neglected Quaternary legacy on biodiversity in the Mountains of Southwest China

It is concluded that the repeated glacial cycles are associated with temporal synchrony of divergence patterns that are themselves structured by the heterogeneity of the montane landscape has of the MSWC, and this orderly process of diversifications has profound implications for conservation.



Ecology Predicts Levels of Genetic Differentiation in Neotropical Birds

This study examines genetic variation in 40 codistributed species of lowland Neotropical rain forest birds that have populations isolated on either side of the Andes, the Amazon River, and the Madeira River to hypothesize that differences in dispersal propensity may explain the observation that understory species contain a significantly greater number of subspecies than do canopy species.

A palaeobiogeographic model for biotic diversification within Amazonia over the past three million years

The history of Psophia, in combination with new geological evidence, provides the strongest direct evidence supporting a role for river dynamics in Amazonian diversification, and the absence of such a roles for glacial climate cycles and refugia.

Amazonia Through Time: Andean Uplift, Climate Change, Landscape Evolution, and Biodiversity

It is shown that Andean uplift was crucial for the evolution of Amazonian landscapes and ecosystems, and that current biodiversity patterns are rooted deep in the pre-Quaternary.

Phylogeographical patterns shed light on evolutionary process in South America

The results suggest a highly complex mosaic of phylogeographical patterns in South America, which is suggestive of high levels of undocumented species diversity.

The Role of Physical Barriers in the Location of Avian Suture Zones in the Guiana Shield, Northern Amazonia

The results indicate that although major Amazonian rivers are often key determinants of taxon boundaries, the “riverine barrier effect” is a synergistic consequence of the wide lower reaches of some rivers, coupled with nonriverine landscape features at the headwaters.

It is found that the Furnariidae exhibit nearly constant rates of lineage accumulation but show evidence of constrained morphological evolution, suggesting that lineage accumulation in tropical continental radiations may not be as limited by ecological opportunities as in temperate or island radiations.

The Causes Of Species Richness Patterns Across Space, Time, And Clades And The Role Of “Ecological Limits”

Critically review the evidence for claims that species richness patterns among regions and clades may be explained by “ecological limits” on diversity over time, and propose how to better study the ecological and evolutionary origins ofspecies richness patterns.

The global diversity of birds in space and time

It is found that birds have undergone a strong increase in diversification rate from about 50 million years ago to the near present, with a number of significant rate increases, both within songbirds and within other young and mostly temperate radiations including the waterfowl, gulls and woodpeckers.

Climate change patterns in Amazonia and biodiversity.

These absolute-dated speleothem oxygen isotope records that characterize hydroclimate variation in western and eastern Amazonia over the past 250 and 20 ka are presented, suggesting that higher biodiversity in western Amazonia, contrary to 'Refugia Hypothesis', is maintained under relatively stable climatic conditions.
