According to the ecological species concept, the more similar two organisms are then the more likely that their needs will overlap, the more likely they will compete over resources such as food and shelter, and therefore the more likely that they are members of the same species.Not surprisingly, the ecological species concept thus is defined particularly in terms of the ecology of organisms.
The ecological species concept claims that species are groups or populations that share the exact same ecological niche. The definition gets a little tricky with organisms that change niches over their development. For examples, some organisms live in the water as larvae, and on land as adults. It's sometimes expanded to include a set of niches.

A definition of species as a set of organisms that is adapted to a particular set of resources (niche) in the environment, which explains differences in form and behaviour between species as adaptations to resource availability. Compare biological species concept, cladistic species concept, phenetic species concept, recognition species concept.
The ecological species concept is a concept of species in which a species is a set of organisms adapted to a particular set of resources, called a niche, in the environment. The ecological species concept should be contrasted with the biological, recognition and cladistic species concepts.
Genetics and the definition of species. I have my own way of making sense of this debate, with which you may or may not agree. I argue that you can update Darwin’s idea of species without too much difficulty, but take account of modern knowledge of genetics, and thereby solve some of the problems inherent in the other species concepts at the same time.
Each of the major species concepts is explained below, along with the advantages and disadvantages of the species concept and which areas of biology use the definition. In several cases below I have combined several finer distinctions of species concepts into a single definition, as I think the distinctions are not so important for an introductory essay.
The focal species concept described in the 2000 regulations differed subtly, but significantly, from the previous “management indicator species” concept used by the Forest Service. Rather than acting as an indicator of the outcome of a specific management prescription, the status and trend of focal species are to allow induction upward to the conservation status of entire suites of species.
Biological species concept. The biological species concept defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define species. Appearance isn't everything Organisms may appear to be alike and.
The Biological Species Concept: They are one single species. Even though species 1 and 5 cannot hybridize, they can share genes via hybridization with intermediate species, therefore there is no reproductive isolation between them. The Ecological Species Concept: They are five distinct species.
Important Concept Of Species. Four most important concept of species are: Typological Species Concept. In this concept, there is a finite number of varieties of living organisms that exist on earth. These types don’t exhibit any relationship with each other. Such varieties are termed as species.
Definition. Biologists and taxonomists have made many attempts to define species, beginning from morphology and moving towards genetics.Early taxonomists such as Linnaeus had no option but to describe what they saw: this was later formalised as the typological or morphological species concept.
The Ecological Species Concept The following definition is a vehicle for conceptual revision, not a standing monolith. A species is a lineage (or a closely related set of lineages) which occupies an adaptive zone minimally different from that of any other lineage in its range and which evolves separately from all lineages outside its range.
Critically assess the Neoclassical and Ecological Economic approaches to Sustainable development. Which do you think is more useful, why? Environmental economics is one of the fields where there are varied approaches of how to deal with the different components.

The “contributory value” focuses on the economic-ecological importance of species diversity: “Even species that have been unsuccessfully examined for human uses are still useful, because they contribute to increases in.
