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...
feather typesFeather types and their distribution on a typical perching bird.(more) bird, (class Aves), any of the more than 10,400 living species unique in having feathers, the major characteristic that distinguishes them from all other animals. A more-elaborate definition would note that they...
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...
They have developed sophisticated systems of nomenclature and classification, which approximate the binomial system (i.e., generic and specific names) found in modern biology. The urge to recognize different kinds of plants and to give them names thus seems to be as old as the human race. 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...
