Comparison of disruption procedures for enumeration of activated sludge floc bacteria by flow cytometry
In a wastewater treatment plant, the degradation process is performed by a variable and mixed community of microorganisms in an aerobic aquatic environment where many bacteria are attached to sludge flocs.
Novelty in phylogeny of gastrotricha: evidence from 18S rRNA gene.
A new view of the evolutionary history of the phylum Gastrotricha is put forward, in which Chaetonotida, and not Macrodasyida, are the most primitive forms of the group, contrary to the commonly held view.
New Species in the Old World: Europe as a Frontier in Biodiversity Exploration, a Test Bed for 21st Century Taxonomy
It is shown that contrary to general belief, developed and heavily-studied parts of the world are important reservoirs of unknown species, and the importance of developing a system that better supports and guides this formidable workforce as they seek to overcome the Taxonomic Impediment and speed up the process of describing the planetary biodiversity before it is too late.
The distribution of meiofauna on back‐reef sandy platforms in the Maldives (Indian Ocean)
A close relationship is observed between meiofauna (especially for the nematodes) and grain size, which appears to control the structure, diversity and trophic composition of the Maldivian meiobenthic assemblages, thus highlighting the high biodiversity existing in the medium-coarse sands.
The Interrelationships of the Gastrotricha Using Nuclear Small rRNA Subunit Sequence Data, with an Interpretation Based on Morphology
Analysis of partial sequences of the 18S rDNA gene of 18 taxa to test morphological estimates of gastrotrich phylogeny and to verify whether controversial interrelationships from previous molecular data are due to poor sampling results are generally compatible with the hypothesised evolutionary scenario based on morphological data, but are in contrast with previous findings from molecules.
Marine gastrotrichs from the Tremiti Archipelago in the southern Adriatic Sea, with the description of two new species of Urodasys
The number of species found was relatively high and comparable with the range of fauna found on the major Italian islands, and a possible evolution of the reproductive system in the genus Urodasys is briefly discussed.
Comparative sperm ultrastructure of Neodasys ciritus and Musellifer delamarei, two species considered to be basal among Chaetonotida (Gastrotricha)
The spermatozoa of two species supposed to be basal to Gastrotricha Chaetonotida, Neodasys ciritus and Musellifer delamarei, were studied in order to supply further elements to the understanding of
Meiofauna as a Tool for Marine Ecosystem Biomonitoring
Meiofauna are the metazoan component of the benthos, and also include large protozoans (e.g. foraminifera). They are defined by their body size (44-1000 μm) and are the most diversified element of
