Abundance of small individuals influences the effectiveness of processing techniques for deep-sea nematodes [PDF]

, 2010
Nematodes are the most abundant metazoans of deep-sea benthic communities, but knowledge of their distribution is limited relative to larger organisms.

Biases and distribution patterns in hard‐bodied microscopic animals (Acari: Halacaridae): Size does not matter, but generalism and sampling effort do

Diversity and Distributions, Volume 29, Issue 7, Page 821-833, July 2023., 2023
Abstract Aim The interplay between distribution ranges, species traits and sampling and taxonomic biases remains elusive amongst microscopic animals. This ignorance obscures our understanding of the diversity patterns of a major component of biodiversity.

Change in the community structure and organic carbon content of meio- and macrobenthos between tidal flat and salt marsh areas colonized by Spartina alterniflora in the Bahía Blanca estuary (SW Atlantic)

Scientia Marina, 2023
Salt marshes are regarded as among the most productive coastal ecosystems, important “blue carbon” sinks and a support for benthic communities with large abundances, whose structure may be strongly influenced by salt marsh vegetation.

Biogeographical Distribution of River Microbial Communities in Atlantic Catchments. [PDF]

Environ Microbiol Rep
We discovered different factors affecting river microbial communities (RMC) diversity and composition across Atlantic catchments in Europe. Prokaryote diversity was mainly influenced by topography and geology, while eukaryotic groups were driven by land use and cover.

Dual stable isotope abundances unravel trophic position of estuarine nematodes [PDF]

, 2005
The role and quantitative importance of free-living nematodes in marine and estuarine soft sediments remain enigmatic for lack of empirical evidence on the feeding habits and trophic position of most nematode species.

Metabarcoding reveals high‐resolution biogeographical and metaphylogeographical patterns through marine barriers

Journal of Biogeography, Volume 50, Issue 3, Page 515-527, March 2023., 2023
Abstract Aim It has been predicted that there should be concordance between biogeographical and phylogeographical processes structuring multi‐species regional assemblages. We hypothesise that oceanographic barriers in the marine environment affect concomitantly the distribution and the connectivity of the marine biota, thus producing congruent ...

Meiofauna communities in exposed sandy beaches on the Galician coast (NW Spain), six months after the Prestige oil spill: the role of polycyclic aromatic hydrocarbons (PAHs)

Scientia Marina, 2010
The effect of polycyclic aromatic hydrocarbons (PAHs) on Galician sandy beach ecosystems, six months after the Prestige oil spill, was evaluated using the meiobenthos at a higher taxon level as an indicator. Meiobenthos community structure, environmental

Impact of farming non-indigenous scallop Argopecten irradians on benthic ecosystem functioning: a case-study in Laizhou Bay, China

Aquaculture Environment Interactions, 2018
The farming of the non-indigenous bay scallop Argopecten irradians in coastal waters generates large amounts of biodeposits that potentially change the trophic pathways and quality of the benthic food web at lower trophic levels such as meiobenthos.

Schizorhynchia Meixner, 1928 (Platyhelminthes, Rhabdocoela) of the Iberian Peninsula, with a description of four new species from Portugal

European Journal of Taxonomy, 2020
During several sampling campaigns in the regions of Galicia and Andalusia in Spain and the Algarve region in Portugal, specimens of twelve species of schizorhynch rhabdocoels were collected.

The first metazoa living in permanently anoxic conditions [PDF]

, 2010
Background Several unicellular organisms (prokaryotes and protozoa) can live under permanently anoxic conditions. Although a few metazoans can survive temporarily in the absence of oxygen, it is believed that multi-cellular organisms cannot spend their ...
