On the Evolution of Genome Size of Birds
Journal of Heredity, 1991We measured genome size (nuclear DNA content) by fluorescence flow cytometry in 55 species of birds representing 12 different orders. Similar studies were performed in approximately 100 species by laboratories using absorption cytophotometry of Feulgen-stained nuclei.

Land plant species (Embryophyta) vary more than 2,300-fold in the size of the holoploid genome (C-value) (see Leitch and Leitch 2012a, this volume) with the extremes at both ends of the scale contributed by angiosperms. At the lower end we find some species of the carnivorous Lentibulariaceae with ultrasmall genomes, e.g.

Estimation of genome sizes of hyperthermophiles
Extremophiles, 1998Genomes of various hyperthermophilic and extremely thermophilic prokaryotes were analyzed with respect to size, physical organization, and 16S rDNA copy number. Our results show that all the genomes are circular, and they are in the size range of 1.6-1.8 Mb for Pyrodictium abyssi, Methanococcus igneus, Pyrobaculum aerophilum, Archaeoglobus fulgidus ...

Genome size and longevity in fish
Experimental Gerontology, 2003The wide variety of genome sizes (measured as C-value) observed across taxa is not related to organismal complexity or number of coding genes. Partial answers to this C-value enigma have been found by establishing associations between C-value and particular phenotypic characteristics.

Genome Size and Operon Content
Journal of Theoretical Biology, 2003Prokaryotic genes are often organized into operons, clusters of genes that are transcribed together. Because all genes in an operon must be transcribed in the same direction, this organization will be reflected in a tendency for nearby genes to have the same orientation.
