Evaluation of sampling methods for periphytic fauna in macrophytes at the Espinhaço Mountain Range Biosphere Reserve, Minas Gerais State, Brazil = Avaliação dos métodos de amostragem para fauna perifítica em macrófitas na Reserva da Biosfera, Serra do Espinhaço, Estado de Minas Gerais, Brasil

Acta Scientiarum: Biological Sciences, 2008
The methods “Jar”, “Manual Removal” and “modified Ekman Dredge” wereevaluated for sampling periphyton fauna associated with aquatic macrophytes. Sixty-three samples were collected from five lentic and three lotic water bodies at the Espinhaço Mountain ...

The fine structure of the midgut epithelium in Xerobiotus pseudohufelandi (Iharos, 1966) (Tardigrada, Eutardigrada, Macrobiotidae)

Journal of Limnology, 2013
The aims of our studies were to describe the ultrastructure of the midgut epithelial cells of the eutardigrade Xerobiotus pseudohufelandi and to determine if there are any differences in the ultrastructure of midgut epithelial cells between males and ...

An upgraded comprehensive multilocus phylogeny of the Tardigrada tree of life

Zoologica Scripta, 2018
Providing accurate animals’ phylogenies rely on increasing knowledge of neglected phyla. Tardigrada diversity evaluated in broad phylogenies (among phyla) is biased towards eutardigrades.

Nearctic freshwater tardigrades: a review

Journal of Limnology, 2007
The distribution and ecology of limno-terrestrial Tardigrada in the Nearctic realm remain poorly known. This is especially true of freshwater tardigrades (i.e., species found in permanently submerged habitats), which have received much less attention ...

An integrative redescription of Hypsibius dujardini (Doyère, 1840), the nominal taxon for Hypsibioidea (Tardigrada: Eutardigrada).

Zootaxa, 2018
A laboratory strain identified as "Hypsibius dujardini" is one of the best studied tardigrade strains: it is widely used as a model organism in a variety of research projects, ranging from developmental and evolutionary biology through physiology and ...

Diverse eggs, diverse species? Production of two egg morphotypes in Paramacrobiotus bifrons, a new eutardigrade species within the areolatus group

The European Zoological Journal
Species within the eutardigrade superfamily Macrobiotoidea are usually differentiated through their eggshell morphology. However, this trait can show very high intraspecific variability and, as consequence, species delimitation is challenging without ...
