Abstract: Salamanders (urodela) have among the largest vertebrate genomes, ranging in size from 10 to 120 pg. The urodela are divided into ten extant families each with a characteristic range in genome size. Although changes in...

Karyotype and genome size in Euterpe Mart. (Arecaceae) species.

Euterpe (Martius, 1823), a genus from Central and South America, has species with high economic importance in Brazil, because of their palm heart and fruits, known as açaí berries. Breeding programs have been conducted to increase yield and establish cultivation systems to replace the extraction of wild material. These programs need basic information about the genome of these species to better ...

Identification of bovine, ovine and caprine pure and binary mixtures of raw and heat processed meats using species specific size markers targeting mitochondrial genome

A specific polymerase chain reaction (PCR) method was applied for identification of bovine (Bos taurus), ovine (Ovis aries) and caprine (Capra hircus) pure and binary mixtures of raw and heat-processed meats. These meats are used in food industry products and/or for direct consumption of consumers. The mitochondrial DNA was amplified as a template in a PCR reaction by use of specific primers re...

Diversification Rates and the Evolution of Species Range Size Frequency Distribution

The geographic range sizes frequency distribution (RFD) within clades is typically right-skewed with untransformed data, and bell-shaped or slightly left-skewed under the log-transformation. This means that most species within clades occupy diminutive ranges, whereas just a few species are truly widespread. A number of ecological and evolutionary explanations have been proposed to account for t...
