Potentilla recta, the sulphur cinquefoil [1] or rough-fruited cinquefoil, is a species of cinquefoil. It is native to Eurasia but it is present in North America as an introduced species, ranging through almost the entire continent except the northernmost part of Canada and Alaska. The plant probably originated in the Mediterranean Basin.
Potentilla / ˌ p oʊ t ən ˈ t ɪ l ə / [1] is a genus containing over 500 species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae.. Potentillas may also be called cinquefoils in English, but they have also been called five fingers and silverweeds.
The sulfur cycle in marine environments has been well-studied via the tool of sulfur isotope systematics expressed as δ 34 S. The modern global oceans have sulfur storage of 1.3 × 10 21 g, [92] mainly occurring as sulfate with the δ 34 S value of +21‰. [93] The overall input flux is 1.0 × 10 14 g/year with the sulfur isotope composition ...
The important sulfur cycle is a biogeochemical cycle in which the sulfur moves between rocks, waterways and living systems. It is important in geology as it affects many minerals and in life because sulfur is an essential element (), being a constituent of many proteins and cofactors, and sulfur compounds can be used as oxidants or reductants in microbial respiration. [1]
For example, some microbe species oxidize sulfide to sulfate and another species will reduce sulfate to elemental sulfur. As a result, a web of chemical pathways mediated by different microbial species transform elements such as carbon, sulfur, nitrogen, and hydrogen, from one species to another.
Drymocallis glandulosa, formerly Potentilla glandulosa, known by the common names Douglas' wood beauty [1] and sticky cinquefoil, is a plant species in the family Rosaceae. It is native to western North America from southwestern Canada through the far western United States and California , into Baja California . [ 2 ]
California ground squirrels deviating from a steady diet of nuts, seeds or grains was "shocking," said Jennifer E. Smith, study lead and associate professor of biology at UW-Eau Claire. "We had ...
Potentilla argentea, known as hoary cinquefoil, [1] silver cinquefoil, [2] silvery cinquefoil, [3] or silver-leaf cinquefoil, [4] is a perennial herb (or forb) in the family Rosaceae. Potentilla argentea is native to Europe, Asia Minor, and Siberia, [ 3 ] and is introduced throughout temperate areas in North America and in New Zealand.
