Resumo
Ants are an important and diverse natural insect group
exhibiting astonishing variation in chromosome number and structure.
Their haploid chromosome numbers range from n = 1 to n =
60 and include diverse karyotypes comprising various different
types of chromosome. This marked variation first attracted attention
over 40 years ago, and has led to several theories concerning
the evolution of chromosome change and the manner in which it
may have promoted and contributed to ant species diversification.
Despite the significance of ants, their chromosome numbers have
been only sporadically documented and assembled. We present
here the Ant Chromosome database – ACdb (www.ants.ufop.br),
which was conceived as a regularly updated online tool for rapid
access to data regarding ant karyology. ACdb is an easy-to-use
database which will advance the accession and dissemination of
cytogenetic knowledge of the Formicidae. At present, it contains
1080 entries of chromosome and karyotype data for 520 named
species from 134 genera in 11 subfamilies. Basic information on
karyotypes and chromosome numbers is provided, along with
relevant karyotype formulae, which summarize chromosomal
structure. ACdb highlights the challenge to ant cytogeneticists to
improve the available chromosome knowledge of the Formicidae.
Chromosome counts are still lacking in several subfamilies and
many genera, while banding data are unavailable for most ant
species. We trust that the database will inspire efforts
