| a putative new hydrostatic skeletal function for the epidermis in monhysterids (nematoda). | the ultrastructure of the epidermis of two monhysterid nematodes (geomonhystera disjuncta and diplolaimella dievengatensis) is studied in detail. the epidermis is composed of discrete uninucleated cells. the cytoplasmic layer of the epidermis between the cuticle and the somatic muscles is very thin and contains bundles of filaments that attach the muscles to the cuticle. the epidermal chords are voluminous and contain the nuclei and most of the cell organelles. in the chords many large electron- ... | 1989 | 18620275 |
| position of pharyngeal gland outlets in monhysteridae (nemata). | in this study an attempt was made to determine the position of the outlets and nuclei of the pharyngeal glands in four monhysterid genera. five eumonhystera spp., seven monhystera spp., and eight monhystrella spp. were studied under the light microscope. longitudinal sections of an undescribed monhystera sp. and cross sections of geomonhystera disjuncta were also studied under the scanning and transmission electron microscope, respectively. the results of the light microscopic studies were incon ... | 1996 | 19277132 |
| transcription, signaling receptor activity, oxidative phosphorylation, and fatty acid metabolism mediate the presence of closely related species in distinct intertidal and cold-seep habitats. | bathyal cold seeps are isolated extreme deep-sea environments characterized by low species diversity while biomass can be high. the håkon mosby mud volcano (barents sea, 1,280 m) is a rather stable chemosynthetic driven habitat characterized by prominent surface bacterial mats with high sulfide concentrations and low oxygen levels. here, the nematode halomonhystera hermesi thrives in high abundances (11,000 individuals 10 cm(-2)). halomonhystera hermesi is a member of the intertidal halomonhyste ... | 2015 | 26637468 |
| differences in life-histories refute ecological equivalence of cryptic species and provide clues to the origin of bathyal halomonhystera (nematoda). | the discovery of morphologically very similar but genetically distinct species complicates a proper understanding of the link between biodiversity and ecosystem functioning. cryptic species have been frequently observed to co-occur and are thus expected to be ecological equivalent. the marine nematode halomonhystera disjuncta contains five cryptic species (gd1-5) that co-occur in the westerschelde estuary. in this study, we investigated the effect of three abiotic factors (salinity, temperature ... | 2014 | 25384013 |
