Exempel på hur man kan använda MICROENVIRONMENTS i en mening

• Hypoxic microenvironments in solid tumors are a result of available oxygen being consumed within 70 to 150 μm of tumor vasculature by rapidly proliferating tumor cells thus limiting the amount of oxygen available to diffuse further into the tumor tissue.
• Beaudry demonstrate how "…changes in the complex mosaic of microenvironments in metropolitan situations are sensitively recorded in the pollen contributions of weedy taxa".
• Colonies of Trichodesmium provide a pseudobenthic substrate for many small oceanic organisms including bacteria, diatoms, dinoflagellates, protozoa, and copepods (which are its primary predator); in this way, the genus can support complex microenvironments.
• A second example occurs in melanoma, where malignantly transformed pigment cells switch back-and-forth between phenotypes of proliferation and invasion in response to changing microenvironments, driving metastatic progression.
• There is a very diverse flora and fauna, because of the many microenvironments, such as streams, rivers, lakes, forests, agricultural land, coppices, pasture, sub-alpine grassland and the unique biotope of the Vikos Gorge.
• Spectra from the PAH thin film in a water-vapor-containing microenvironment indicate measurable change due to solar irradiation in orbit, while three other nominally water-free microenvironments show no appreciable change.
• Purpureocillium lilacinum is highly adaptable in its life strategy: depending on the availability of nutrients in the surrounding microenvironments it may be entomopathogenic, mycoparasitic, saprophytic, as well as nematophagous.
• Trichodesmium erythraeum plays an important role in aquatic microenvironments, specifically in warm and nutrient-scarce oceans, where its diazotrophic metabolism contributes a substantial amount of fixed nitrogen (~50% of total N from all six Trichodesmium species) to these ecosystems.
