Brief note on Intraspecific relations between species
The interactions between members of the same species are known as intraspecific relations and these are frequently very strong varying from open conflict to gregariousness.
Complete information on the diversity of species within an ecosystem
One fascinating attribute of an ecosystem is the diversity of species that make up the system. A diversity of functional groups is naturally to be expected because the food webs in an ecosystem involve autotroph, herbivores, carnivores, detritivores, and so on.
What is Sibling Species ?
The species of some genera are reproductively isolated but are similar in outward appearance or morphology. These are called sibling species. They live in the same geographical area. They can be identified by their breeding time, preferred habitats and behavior.
Write a short note on Sub-species
Mayr (1969) defined a sub-species as a drographically isolated population of a species which are capable of interbreeding and producing fertile hybrids.
What are the species and species concepts?
Species is the fundamental biological unit of classification. John Ray, an English naturalist coined the term species. Taxonomist defined species as a group of individuals that resemble each other in most of their visible characters or morphological characters. This concept is not applicable to some animals. E.g. Males of some birds are colourful with beautiful plumage than the females.
The phenomenon of interdependence among different species of a habitat with examples
