We illustrate this approach with reference to the red fox (Vulpes vulpes), the most widely distributed extant wild terrestrial mammalian species [14], extensively studied throughout its geographic range due to its ecological, economic, and cultural importance e.g., [15], [16].
With reference to the "organizing importance" of evolutionary events, the ToL has been used to apply a strictly hierarchical classification system to extant organisms.
Uglow repeatedly makes reference to the dearth of archival sources pertaining to her subject: Losh destroyed most of her own writings, and her journals, if extant, are missing.
Here, we discuss the controversial question whether or not extant air-breathing fishes, such as mudskippers, amphibious gobioids that inhabit mangrove swamps, can be interpreted as living model organisms, with reference to the earliest land plants.
Second, in the form of a prospective observational study we aim to verify in this setting a rapid molecular assay for the detection of MRSA, with reference to extant culture-based methods.
Efforts to do so, however, are stymied by the fact that programs have been designed without reference to extant theory, conceptual models and frameworks, or prior research.
We qualitatively compared the content of factors across measures, with interpretation aided by reference to extant global mental health literature, including previous work in Afghanistan [ 24, 51].
Tentative a priori constructs or variables guide the investigation, but no relationships between such constructs or variables are assumed so far: "Thus, investigators should formulate a research problem and possibly specify some potentially important variables, with some reference to extant literature.
A more explicit spatial perspective on sustainability transitions contributes to the extant transitions literature in three ways.
