Faster Speciation and Reduced Extinction in the Tropics Contribute to the Mammalian Latitudinal Diversity Gradient
Jonathan Rolland and colleagues show that the gradient of increased mammalian diversity towards the tropics is driven by both faster speciation and reduced extinction.

RPANDA : an R package for macroevolutionary analyses on phylogenetic trees.
Summary A number of approaches for studying macroevolution using phylogenetic trees have been developed in the last few years. Here, we present RPANDA, an R package that implements model-free andExpand

What causes latitudinal gradients in species diversity? Evolutionary processes and ecological constraints on swallowtail biodiversity.
The latitudinal diversity gradient (LDG) is one of the most striking ecological patterns on our planet. Determining the evolutionary causes of this pattern remains a challenging task. To address thisExpand

Shotgun Mitogenomics Provides a Reference Phylogenetic Framework and Timescale for Living Xenarthrans
Xenarthra (armadillos, sloths, and anteaters) constitutes one of the four major clades of placental mammals. Despite their phylogenetic distinctiveness in mammals, a reference phylogeny is stillExpand

Origin and diversification of living cycads: a cautionary tale on the impact of the branching process prior in Bayesian molecular dating
BackgroundBayesian relaxed-clock dating has significantly influenced our understanding of the timeline of biotic evolution. This approach requires the use of priors on the branching process, yetExpand

The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae)
Summary The tropical Andes of South America, the world's richest biodiversity hotspot, are home to many rapid radiations. While geological, climatic, and ecological processes collectively explainExpand

Macroevolutionary perspectives to environmental change.
Predicting how biodiversity will be affected and will respond to human-induced environmental changes is one of the most critical challenges facing ecologists today. Here, we put current environmentalExpand

Amazonia is the primary source of Neotropical biodiversity
Significance Amazonia is not only the world’s most diverse rainforest but is also the region in tropical America that has contributed most to its total biodiversity. We show this by estimating andExpand

Islands as model systems in ecology and evolution: prospects fifty years after MacArthur-Wilson.
The study of islands as model systems has played an important role in the development of evolutionary and ecological theory. The 50th anniversary of MacArthur and Wilson's (December 1963) article,Expand

Global patterns of insect diversification: towards a reconciliation of fossil and molecular evidence?
Macroevolutionary studies of insects at diverse taxonomic scales often reveal dynamic evolutionary patterns, with multiple inferred diversification rate shifts. Responses to major past environmentalExpand
