chromploid: An R package for chromosome number evolution across the plant tree of life. [PDF]

open access: yesAppl Plant Sci, 2018
Premise of the Study Polyploidy has profound evolutionary consequences for land plants. Despite the availability of large phylogenetic and chromosomal data sets, estimating the rates of polyploidy and chromosomal evolution across the tree of life remains

Recombination, chromosome number and eusociality in the Hymenoptera. [PDF]

open access: yesJ Evol Biol, 2015
Extraordinarily high rates of recombination have been observed in some eusocial species. The most popular explanation is that increased recombination increases genetic variation among workers, which in turn increases colony performance, for example by ...

Chromosome number is key to longevity of polyploid lineages.

open access: yesNew Phytologist, 2021
Polyploidy is ubiquitous and often recursive in plant lineages, most frequently resulting in extinction but occasionally associated with great evolutionary success.

A deep dive into the ancestral chromosome number and genome size of flowering plants.

open access: yesNew Phytologist, 2020
Chromosome number and genome variation in flowering plants has stimulated a blossoming number of speculations about the ancestral chromosome number of angiosperms, but estimates so far remain equivocal.

Diptera and Drosophila Karyotype Databases: A Useful Dataset to Guide Evolutionary and Genomic Studies

open access: yesFrontiers in Ecology and Evolution, 2022
Karyotypes and chromosome data have been widely used in many subfields of biology over the last century. Unfortunately, this data is largely scattered among hundreds of articles, books, and theses, many of which are only available behind paywalls.

Macroevolutionary insights into sedges (Carex: Cyperaceae): The effects of rapid chromosome number evolution on lineage diversification

open access: yesJournal of Systematics and Evolution, 2021
Changes in holocentric chromosome number due to fission and fusion have direct and immediate effects on genome structure and recombination rates. These, in turn, may influence ecology and evolutionary trajectories profoundly.
