Cariotipos de los murciélagos vampiros (chiroptera: desmodinae)
, 1976 Vampire bats are clearly members of the family Phyllostomatidae but their affinities within the family are less obvious. Investigations into the karyotypes of the three monotypic genera (Desmodus, Diaemus and Diphylla ) were made to determine if chromosomal data might reveal the phylogenetic affinities of the subfamily Desmodinae.

El cariotipo de Chaetanthera renifolia (J. Remy) Cabrera (Asteraceae) [PDF]
Gayana. Botánica, 2010 The karyotype of Chaetanthera renifolia (J. Remy) Cabrera from Chile was examined. The species has 2n = 2x = 44 chromosomes, with lm+ lst + 2st-sat+ 17t+ lt-satchromosomes. The reported karyotype is bimodal and very asymmetric (AsK % = 86.6, TF % = 13.4 and Syi % = 15.5).
