Polyploid incidence and evolution.
TLDR
New estimates for the incidence of polyploidy in ferns and flowering plants are presented based on a simple model describing transitions between odd and even base chromosome numbers, and it is indicated that ploidy changes may represent from 2 to 4% of speciation events in flowering plants and 7% in f Ferns.

Estimating a binary character's effect on speciation and extinction.
TLDR
This work describes how to calculate the probability that a group of extant species would have evolved as observed, given a particular model of the character's effect, under a simple model of evolution (the "BiSSE model, binary-state speciation and extinction). Expand
The Evolutionary Consequences of Polyploidy

  • 2 November 2007
TLDR
This Review examines the short-term effects of polyploidization on cell size, body size, genomic stability, and gene expression and the long- term effects on rates of evolution. Expand
Estimating trait-dependent speciation and extinction rates from incompletely resolved phylogenies.
TLDR
2 likelihood methods are developed that can be used to infer the effect of a trait on speciation and extinction without complete phylogenetic information, generalizing the recent binary-state speciationand extinction method. Expand
The Evolutionary Enigma of Sex

  • 1 July 2009
TLDR
This article reviews early models to explain the evolution of sex and why they failed to do so, and clarifies the conditions that are most likely to explain why sex is so common. Expand
Sex Determination: Why So Many Ways of Doing It?
TLDR
The current understanding of how and why sex determination evolves in animals and plants is reviewed. Expand
Probabilistic models of chromosome number evolution and the inference of polyploidy.
TLDR
A series of likelihood models are presented, each representing a different hypothesis regarding the evolution of chromosome number along a given phylogeny, to reconstruct ancestral chromosome numbers and to estimate the expected number of polyploidization events and single chromosome changes (dysploidy) that occurred along a phylogeny. Expand
Evolution of sex: Resolving the paradox of sex and recombination
TLDR
New studies indicate that this discrepancy might result from the fact that previous models have ignored important complexities that face natural populations, such as genetic drift and the spatial structure of populations. Expand

A Biologist's Guide to Mathematical Modeling in Ecology and Evolution
TLDR
There are two related, but philosophically distinct, approaches to scientific inference: “Classical” statistical analysis is most closely allied with the frequency interpretation, whereas “Bayesian” analysis is allied withThe subjective interpretation. Expand
