We tracked the phylogenetic signal of this niche conservatism in far related and functionally contrasted groups of common soil protists (Bacillariophyta, Cercomonadida, Ciliophora, Euglyphida and Kinetoplastida) along a humid but increasingly cold elevational gradient in Switzerland. Protist diversity ...
Make sure to provide two commonalities and two differences between these groups. You must describe/define each one of these. Compare and contrast primary and secondary endosymbiosis in the evolution of chloroplasts. Where did the chloroplasts of each of the photosynthetic protist...
Plant cells, which are surrounded by stiff cell walls (see Sect. “Extracellular matrix”), rarely show cell protrusions. A notable exception are plant root hairs, which are tubular extensions of root epidermal cells. Similar to the microvilli of animal cells, they greatly increase the cell sur...
To compare cellular growth and biomass of the smallest oceanic plastidic protists and cyanobacteria, 14CO2 fixation by flow cytometrically enumerated and sorted Pro, Syn, Pl-S and Pl- L cells was measured at the end of the light period (12 h) and at the end of the following 12-h dark...
Yields of genomic DNA with PCR-identifiable 18S rRNA gene sequence from single cells was low (15% of aplastidic cell sorts, and 7% of plastidic sorts) and tests with alternate primers and comparisons to metabarcoding did not reveal phylogenetic bias in the major protist groups. There was ...
Concepts about specific relationships among various groups of protists are diverse and protist taxonomy is consequently unstable. In order to investigate t... RM Smith,DJ Patterson - 《Proceedings of the Royal Society B Biological Sciences》 被引量: 33发表: 1986年 2014 National Park visitor spendi...
's original proposal, remains the dominant description of biological evolution. The cases in point include the origin of complex RNA molecules and protein folds; major groups of viruses; archaea and bacteria, and the principal lineages within each of these prokaryotic domains; eukaryotic supergroups;...

The growth rates of the Pl-S and Pl-L, estimated by the two methods, were statistically similar (Supplementary Fig. 6), proving that the tracer method gave realistic estimates of growth rates of plastidic protists. The tracer-derived growth rates of the Pro and Syn were 2–4 times ...
