Non-Dimensional Species Concept: This concept may suggest a way of defining species that doesn’t rely on specific dimensional or quantitative criteria. Instead, it could focus on qualitative or structural features to identify and differentiate species. In essence, it would not be based on any particular measurable characteristics, such as size, shape, or genetic distance, but rather on other aspects of an organism’s biology or ecology.
Multidimensional Species Concept: This concept implies that species are defined by multiple dimensions or criteria, which may include a combination of morphological, genetic, ecological, and behavioral characteristics. In contrast to a one-dimensional concept, which relies on a single criterion, a multidimensional species concept considers a broader set of factors when defining and identifying species. It acknowledges the complexity of species boundaries and recognizes that different aspects of an organism’s biology may need to be considered.
