In biology, the definition of species goes by this:“Species is the lowest taxonomic rank and the most basic unit or category of biological classification”. One can also define species as an individual belonging to a group of organisms (or the entire group itself) having common characteristics ...
Biology definition:Pioneer speciesis the first ones to colonize a bare substrate in primary succession while first to colonize a destroyed habitat in secondary succession.Examples:(1) a pioneer species of lyme grass (Leymus arenarius) on a barren land of sand, (2) pioneer species ofplants(e.g...
Physiological variation in Meloidogyne species is discussed with examples in the 4 commonest species and a definition is given of the term biological race. Ecological factors affecting root-knot nematodes are outlined with special reference to the distribution of M. incognita, M. hapla and M. ...
All along this history, two very different attitudes have co-existed regarding the definition of the taxonomic category of species. The first one, often preferred by the theoreticians and historians of sciences, and by laboratory biologists with little experience of organisms in nature, consists in...

EBV definition We thus define the essential biodiversity variable for species distributions (SD EBV) as the probability of occurrence over contiguous spatial and temporal units addressing the global extent of a species group consisting of one to many members. With support from models, this space–tim...
The generally accepted definition of a species is Mayr's biological species concept, which fits especially well with a majority of animal species. His concept focuses on the reproductive boundary. Now, realizing that there are no significant continuous changes within a given species at the genome ...
