Quaternary glacial–interglacial cycles repeatedly forced thermal zones up and down the slopes of mountains, at all latitudes. Although no one doubts that these temperature cycles have left their signature on contemporary patterns of geography and phylogeny, the relative roles of ecology and evolution are not well understood, especially for the tropics. To explore key mechanisms and their interactions in the context of chance events, we constructed a geographical range-based, stochastic…

Sufficient versus optimal climatic stability during the Late Quaternary: using environmental quality to guide phylogeographic inferences in a Neotropical montane system

Results suggest that in these tropical montane ecosystems, cycles of population connectivity and isolation followed a pattern opposite to that typically described for temperate or lowland tropical ecosystems: namely, higher connectivity during the colder glacials, with isolation in montane refugia during the interglacials, including today.

Climate change and topography as drivers of Latin American biome dynamics

The distribution of species in the present is just a snapshot in time after millions of years of change. Pleistocene climatic cycles, varying from 100 ky to sub-millennial scales, played an important

Modeling the ecology and evolution of biodiversity: Biogeographical cradles, museums, and graves

A spatially explicit, mechanistic model that simulates the history of life on the South American continent, driven by modeled climates of the past 800,000 years, and captures the broad features of maps of contemporary species richness for birds, mammals, and plants.

Specialization in Plant-Hummingbird Networks Is Associated with Species Richness, Contemporary Precipitation and Quaternary Climate-Change Velocity

The results suggest that both ecological and evolutionary processes at Quaternary time scales can be important in driving large-scale geographical patterns of contemporary biotic specialization, at least for co-evolved systems such as plant-hummingbird networks.

Inferring responses to climate dynamics from historical demography in neotropical forest lizards

A comparative framework is applied to test for concerted demographic changes in response to climate shifts in the neotropical lowland forests, finding support for population shifts but fail to detect idiosyncratic responses across species and uniformity of within-species responses across forest regions.

Neotropical refugia

Patterns of endemism in the Neotropics have been explained by restriction of forest to ‘refugia’ in arid cold-stages of the Quaternary (Haffer J (1969) Speciation in Amazonian forest birds. Science

Reconstructing the Geography of Speciation from Contemporary Biodiversity Data

The model and analyses show that broad-scale comparative methods can be a powerful complementary approach to more focused genomic analyses in the study of the patterns and mechanisms of speciation.

Radiation of tropical island bees and the role of phylogenetic niche conservatism as an important driver of biodiversity

It is argued that phylogenetic niche conservatism is an important driver of tropical island bee biodiversity but that this phylogenetic inertia also leads to major extinction risks for tropical ectotherms under future warming climates.



The Fate of Clades in a World of Recurrent Climatic Change: Milankovitch Oscillations and Evolution

Clades that have survived climatic shifts during at least one entire period of the longest significant Milankovitch oscillations (100 kyr) are named β-clades, which lead to sorting at many levels of genealogic inclusiveness.

Both DNA sequence and nSSR data reflect contrasting demographic histories in lower Mesoamerica and Amazonia, and Amazon populations show weak phylogeographic structure and deviation from drift–mutation equilibrium indicating recent population expansion.

The tropics: cradle, museum or casino? A dynamic null model for latitudinal gradients of species diversity.

A simple dynamic null model is presented that predicts higher species diversity and higher extinction and speciation rates in the tropics, and a strong influence of range movements in shaping the LDG.

Quaternary Ice-Age dynamics in the Colombian Andes: developing an understanding of our legacy.

Present-day C3-dominated paramo vegetation is therefore not an analogue for past C4-dominated vegetation (with abundant Sporobolus lasiophyllus), and during the last glacial cycle the ecological tolerance of Quercus may have increased.

Small mammal diversity loss in response to late-Pleistocene climatic change

It is shown that across future landscapes there will be some unanticipated effects of global change on diversity: restructuring of small mammal communities, significant loss of richness, and perhaps the rising dominance of native ‘weedy’ species.

Observations on Late Pleistocene cooling and precipitation in the lowland Neotropics

Although accurate reconstructions of Amazonian palaeoclimates are central to understanding the distribution and history of Neotropical biodiversity, current reconstructions based on proxy data are


It is argued here that all three of these outcomes involve evolutionary processes, suggesting that the speed with which a population adapts to a changing environment affects invasion rate of new habitat and thus migration rate, population growth rate and thus probability of extinction, and growth and mortality of individual plants and thus productivity of regional vegetation.

Out of the Tropics: Evolutionary Dynamics of the Latitudinal Diversity Gradient

A global analysis of genera and subgenera of marine bivalves over the past 11 million years supports an “out of the tropics” model, in which taxa preferentially originate in the Tropics and expand toward the poles without losing their tropical presence.

Global Warming, Elevational Range Shifts, and Lowland Biotic Attrition in the Wet Tropics

It is concluded that tropical lowland biotas may face a level of net lowlandBiotic attrition without parallel at higher latitudes and that a high proportion of tropical species soon faces gaps between current and projected elevational ranges.

Range shifts and adaptive responses to Quaternary climate change.

The unprecedented rates of climate changes anticipated to occur in the future, coupled with land use changes that impede gene flow, can be expected to disrupt the interplay of adaptation and migration, likely affecting productivity and threatening the persistence of many species.
