What did Joseph Connell do?

What is the interaction between Chthamalus and balanus?

Balanus can out-compete Chthamalus by crowding or smothering, but Chthamalus can occupy higher tide levels than Balanus because it is more resistant to desiccation. Lower on the shore, acorn barnacles mix in with the Endocladia (Turfweed) assemblage, and are also common on mussel shells.

What does the intermediate disturbance hypothesis state?

The intermediate disturbance hypothesis predicts that the highest diversity will occur at levels of moderate disturbance. We measured the species diversity, abundance, and species diversity of bacteria on the human body in relation to disturbance by washing.

Why Chthamalus Cannot live higher up the shore?

Chthamalus is more tolerant of physical stresses than Semibalanus, and can therefore survive in the high-shore, where it has a ‘spatial refuge’ beyond the limits of Semibalanus. In the midshore, however, Semibalanus thrives and competitively excludes Chthamalus by undercutting or overgrowing it.

What did Connell’s experiment with Balanus and Chthamalus barnacles discover?

The classic experimental demonstration of competition in the field was done by Joseph Connell (1961a, 1961b) on the barnacle species Chthamalus stellatus and Balanus balanoides. He found that whenever he removed Balanus, Chthamalus was able to survive in the lower regions of the intertidal zone.

What level of disturbance gives the most diversity?

intermediate disturbance
The intermediate disturbance hypothesis predicts that the highest diversity will occur at levels of moderate disturbance. We measured the species diversity, abundance, and species diversity of bacteria on the human body in relation to disturbance by washing.

Which ecosystems are likely to be the most diverse?

Tropical forests are some of the most diverse ecosystems on earth.

Which pyramid of ecosystem is always upright?

Pyramid of energy
Pyramid of energy is the only pyramid that can never be inverted and is always upright. This is because some amount of energy in the form of heat is always lost to the environment at every trophic level of the food chain.
