RPANDA: an R package for macroevolutionary analyses on phylogenetic trees
TLDR
RPANDA is an R package that implements model‐free and model‐based phylogenetic comparative methods for macroevolutionary analyses and provides investigators with a set of tools for exploring patterns in phylogenetic trees and fitting various models to these trees, thereby contributing to the ongoing development of phylogenetics in the life sciences.
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.
What causes latitudinal gradients in species diversity? Evolutionary processes and ecological constraints on swallowtail biodiversity.
TLDR
The latitudinal diversity gradient (LDG) observed in swallowtail butterflies is caused by climatically driven changes in both clades based on evidence of responses to cooling and warming events, and distinct biogeographical histories constrained by tropical niche conservatism and niche evolution.
Origin and diversification of living cycads: a cautionary tale on the impact of the branching process prior in Bayesian molecular dating
TLDR
All dating analyses must involve a model selection process using Bayes factors to select between a Yule or birth-death prior, in particular on ancient clades with a potential pattern of high extinction, as well as providing new insights into the history of cycad diversification.
The abiotic and biotic drivers of rapid diversification in Andean bellflowers (Campanulaceae)
TLDR
It is shown that speciation and extinction are differentially influenced by abiotic factors: speciation rates rose concurrently with Andean elevation, while extinction rates decreased during global cooling.
Islands as model systems in ecology and evolution: prospects fifty years after MacArthur-Wilson.
TLDR
P prospects for research on islands are highlighted to improve understanding of the ecology and evolution of communities in general and how attributes of islands combine to provide unusual research opportunities, the implications of which stretch far beyond islands.
Shotgun Mitogenomics Provides a Reference Phylogenetic Framework and Timescale for Living Xenarthrans
TLDR
Diversification analyses showed Xenarthra to be an ancient clade with a constant diversification rate through time with a species turnover driven by high but constant extinction, and to split armadillos into two distinct families Dasypodidae and Chlamyphoridae to better reflect their ancient divergence.
Amazonia is the primary source of Neotropical biodiversity
TLDR
It is found that there has been extensive interchange of evolutionary lineages among different regions and biomes, over the course of tens of millions of years, and Amazonia stands out as the primary source of diversity, which can be mainly explained by the total amount of time Amazonian lineages have occupied the region.
Macroevolutionary perspectives to environmental change.
TLDR
This work builds on research in palaeontology and recent developments in phylogenetic approaches to ask how macroevolution can help us understand how environmental changes have affected biodiversity in the past, and how they will affect biodiversity inThe future.
Global patterns of insect diversification: towards a reconciliation of fossil and molecular evidence?
TLDR
Large-scale insect diversification dynamics at family level is investigated using two distinct types of diversification analyses on a molecular timetree representing ca.
