PAINE Department of Zoology, University of Washington, Seattle, Washington Though longitudinal or latitudinal gradients in species diversity tend to be well described in a zoogeographic sense, they also are poorly under-stood phenomena of major ecological interest. The concept of a keystone species was first introduced by University of Washington professor, Robert T. Paine in 1969. Robert T. Paine, who passed away on 13 June 2016, is among the most influential people in the history of ecology.

Some species, like the starfish in Robert Paine’s first experiment, which were not as abundant as some other species, can have large effects on the structure of their ecosystems. Reduction and recovery of keystone predation pressure after disease-related mass mortality. Activity: No “Paine” No Gain v In the 1960s, Robert Paine, and ecologist at the University of Washington in the United States, conducted an experiment to determine the effect of predators on the stability of an ecosystem.

By 1991, "Food Web Complexity and Species Diversity" was considered a classic ecological paper, and after 50 years it continues to influence ecological theory and conservation biology.

To determine the degree to which Pisaster influenced the distribution and abundance of species, Paine chose two similar stretches Der Sozialpsychologe Muzafer Sherif, damals Professor für Psychologie an der Universität von Oklahoma, war der Initiator dieses Experiments und lieferte damit zugleich einen Meilenstein für die Frage, ob und wie friedensstiftend gemeinsame Herausforderungen sowie übergeordnete Ziele auf Gruppen wirken. A Bayesian network approach to trophic metacommunities shows that habitat loss accelerates top species extinctions. Climate shapes population variation in dogwhelk predation on foundational mussels. Robert Paine changed the science of ecology profoundly. Bob Paine was an ecologist who conducted experiments along the coast of Washington state during the 1960s. Removal of the top predator allows the populations of all lower trophic levels to increase. He was also concerned with confiscating the estates of departed Loyalists and with suppressing the rebellion led by Daniel Shays of impoverished Revolutionary soldiers. Covid-19 Pandemie in Deutschland nach den offiziellen Zahlen des Robert-Koch-Instituts. Paine’s development of the concepts of keystone species, trophic cascades, and patch dynamics are milestones in community ecology. American zoologist Robert Paine coined the term trophic cascade in 1980 to describe reciprocal changes in food webs caused by experimental manipulations of top predators. In the late 1960s, robert paine conducted landmark studies on diversity in the rocky intertidal zone comparing the species diversity in control plots with diversity in experimental plots from which he removed the top predator, sea stars.

Paine's pioneering experiments, and his coining of the term “keystone species” prompted the search for keystones in other communities, and would lead him to another seminal idea. An ecologist by trade, Paine was fascinated by the environmental roles of top predators. E ven in 1963, one had to go pretty far to find places in the United States that were not disturbed by people. Robert Paine’s experiment tested the idea that the structure and composition of the intertidal community at the tip of the Olympic peninsula in Washington’s Mukkaw Bay was controlled from the top down by the predatory starfish Pisaster ochraceus.When starfish were … In the 1980s others used the term to describe changes in aquatic ecosystems arising from factors such as sudden increases in predatory… Zimmer RK, Ferrier GA, Kim SJ, Ogorzalek Loo RR, Zimmer CA, Loo JA.  |  The astute observations of Janzen and Connell have, like Robert Paine's experiment with starfish, been thought of as perhaps true but nevertheless mere idiosyncrasies of the particular environment from which they were described. 14.12.2017 | Experiment.
