The paper describes work in progress the application of process-oriented modeling to situation assessment within a research project in limnology. In the field study, some 50 lakes in Southern Germany are monitored in order to explore and document the changes in the distribution of a particular aquatic plant, Najas marina, and understand their preconditions. The ultimate objective is using this ...
At present, Joostella marina Quan et al. 2008 is the sole species with a validly published name in the genus Joostella, family Flavobacteriacae, phylum Bacteriodetes. It is a yellow-pigmented, aerobic, marine organism about which little has been reported other than the chemotaxonomic features required for initial taxonomic description. The genome of J. marina strain En5(T) complements a list of...
A numerical model of nitrogen uptake and growth was developed for the temperate seagrass Zostera marina L. Goals were to evaluate the relative effects of light and nitrogen availability on nitrogen uptake and partitioning between leaf and root tissue. and to estimate nitrogen concentrations in the sedmen t and water column required to saturate growth. Steady-state predichons are quite robust wi...
Two new compounds-a trioxilin and a sulfoquinovosyl diacylglycerol (SQDG)-were isolated from the methanolic extract of the heterotrophic dinoflagellate Oxyrrhis marina cultivated by feeding on dried yeasts. The trioxilin was identified as (4Z,8E,13Z,16Z,19Z) -7(S),10(S),11(S)-trihydroxydocosapentaenoic acid (1), and the SQDG was identified as (2S)-1-O-hexadecanosy-2-O-docosahexaenoyl-3-O-(6-sul...
Excess nutrients are potential factors that drive phase shifts from seagrasses to macroalgae. We carried out a manipulative field experiment to study the effects of macroalgae Ulva pertusa loading and nutrient addition to the water column on the nitrogen (N) and carbon (C) contents (i.e., fast indicators) as well as on the morphology and structure (i.e., slow indicators) of Zostera marina. Our ...
The genus Oxyrrhis is a heterotrophic dinoflagellate found in diverse marine environments. spp. have received attention owing to their ecological and industrial importance, high lipid contents, docosahexaenoic acid formation. To the best of our knowledge, contrary O. marina, ecophysiological characterization studies on maritima not yet been reported. Therefore, we investigated taxonomy ecophysi...
Reseña sobre Silvia Marina Arrom, La Güera Rodríguez. Mito y mujer (México: Turner Noema, 2020).
This study evaluated the freshwater use of two mangrove species (R. mucronate: Rhizophora mucronata and A. marina: Avicennia marina) growing in a coastal area Djibouti City on Moucha Island Djibouti. We accomplished this by comparing hydrogen oxygen stable isotope ratios (δ2H δ18O) body water with those creek water, soil groundwater, rainwater samples. Line-conditioned excess (lc-excess) was ca...
As a result of urbanization, coastal environments are being disturbed by various anthropogenic pressures. These concentrated in harbor areas where the addition artificial structures and presence pollutants seems to favor settlement non-indigenous species. Most studies on these organisms often carried out single time window without integrating temporal variability. Here, we analyzed multi-year p...
This paper describes the nearly complete embryonic cell lineage of the terrestrial nematode, Halicephalobus gingivalis, up to somatic muscle contraction, resulting in the formation of 536 cells, of which 24 undergo programmed cell death. Halicephalobus gingivalis has a 94% lineage homology with both Caenorhabditis elegans and Pellioditis marina, and a fate homology of only 86% and 78%, respecti...
