The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Understanding patterns and processes in biological diversity is a critical task given current
and rapid environmental change. Such knowledge is even more essential when the taxa …

In recent decades, the use of molecular techniques in rotifers has revealed the existence of
many cryptic species. Although strong competition is expected among cryptic species, these …

Mitonuclear discordance across taxa is increasingly recognized as posing a major
challenge to species delimitation based on DNA sequence data. Integrative taxonomy has …

Knowledge and estimates of species richness at all scales are biased both by our
understanding of the evolutionary processes sha** diversity and by the methods used to …

Precise identification of species is critical for the study of biogeography of plankton and for
applying laboratory culture results to the same organism in situ. Traditionally, identification …

The defining feature of the life cycle in monogonont rotifers such as Brachionus plicatilis
(Muller) is alternation of asexual and sexual reproduction (mixis). Why sex is maintained in …

Rotifera comprise about 2,000 species (Segers 2007) of microscopic animals, usually much
less than 1 mm in length, characterized by the presence of a ciliated corona and a muscular …

The analysis of ecological niche is an important task to correctly identify the role exerted by
species within ecosystems, to assess their vulnerability, to plan effective measures …

Monogononta is the most speciose class of rotifers, with more than 2,000 species. The
monogonont genus Brachionus is widely distributed at a global scale, and a few of its …
