Sorry, no etymologies found.
He expanded his work to other carbonaceous meteorites and says he was completely surprised when he began to find the filaments and round coccoid shapes so common to the microbial world of Earthly bacteria.
Modern examples including coccoid cyanobacterium which are thought to be descendants of a 1,900 million year old form, thus representing one of the longest continuing biological lineages known.
An estimated 95 percent of the surviving population of native Bermuda cedar (Juniperus bermudiana) was destroyed between 1946 and 1951, following the accidental introduction of two coccoid scale insects.
Our results could be interpreted as evidence that the flagellates released a substance inducing colony formation in Chlorella, similar to predator-induced morphological changes in zooplankton (Dodson, 1989) and in coccoid green algae (Hesssen and van Donk, 1993).
Symbiodinium can be characterized as follows; (i) five rows of crystalline deposits forming an arc, situated near the sulcus region, (ii) each crystalline layer was 80-130 nm thick, (iii) the cluster could refract and polarize light in the manner of amorphous materials and noticeably deflected UV more than blue or green light, and (iv) they disappeared in the nocturnal coccoid stage.
Maximum transformations to the motile stage and the coccoid stage were estimated to have occurred by 10: 00 and 00: 00 respectively.
There is no diurnal morphological change, and the cells are very similar to the coccoid stage cell in cultured strains.
Symbiodinium in culture show daily morphological changes between a flagellated gymnodinioid stage (motile stage) in daylight and a non-flagellated spherical stage (coccoid stage) at night
Symbiodinium in host animals usually maintain a coccoid morphology
The degradation of the crystal clusters during transformation from the motile stage to the coccoid stage indicates that they can be rapidly digested within the cell; and the uric acid can potentially be recycled as a nitrogen source as proposed by Clode
