Food web is an important conceptual tool for illustrating the feeding relationships among species within a community, revealing species interactions and community structure, and understanding the ...

A phylogenetic tree, also known as a phylogeny, is a diagram that depicts the lines of evolutionary descent of different species, organisms, or genes from a common ancestor. Phylogenies are useful ...

A diagram bacterial point of view, they concede, would look a lot busier because genetic diversity of bacteria is much greater and there’s quite a lot more bacteria than there are mammals.

A diagram shows the arrangement of the new species’ eyes. On the worm, these eyes look like small black dots. A diagram (left) and close-up photo (right) show the eyes of a Prosthiostomum ...

Park rangers in Chester County, Pennsylvania, found an invasive snakehead fish in the Schuylkill River this week.

Experts estimate that up to 8.7 million species may inhabit the planet (about 15,000 are discovered every year). “We expect the circle to broaden,” says Karen Cranston, a computational ...

Experts went back and forth, describing two species and then recombining them. Local common names, misspellings and “deformed” scientific diagrams only added to the confusion, the study said.

The paper represents the first time we’ve been able to trace the entirety of the brain of a species. Although evolutionarily apart, the genes that direct neural connections in C. elegans are also ...

The diagram below is an example of part of a food web in a Scottish loch. If one species is lost from a food web all the others are affected. Other populations will also be affected. For instance ...
