Joseph Hurd Connell FAA (born October 5, 1923[1]) is an American ecologist. He earned his MA degree in zoology at the University of California, Berkeley and his PhD at Glasgow University.[2] Connell’s first research paper examined the effects of interspecific competition and predation on populations of a barnacle species on the rocky shores of Scotland.[3] According to Connell, this classic paper is often cited because it addressed ecological topics that previously had been given minor roles.[2] Together, with a subsequent barnacle study on the influence of competition and desiccation,[4] these two influential papers have laid the foundation for future research and the findings continue to have relevance to current ecology.[5] His early work earned him a Guggenheim fellowship in 1962[6] and the George Mercer Award in 1963.[7]

In 2010, a Symposium was held in his honour by the Ecological Society of America said that "Connell’s observations, insights, syntheses, and example have motivated education and research in population and community ecology for over six decades".[8] Among his important works are the Connell–Slatyer model of ecological succession (facilitation, tolerance and inhibition) and the Janzen-Connell hypothesis that explains plant-species diversity in tropical forests.[9] Other notable works are his 1978 intermediate disturbance hypothesis[10] and his thirty-year study of corals in the Great Barrier Reef.[11]

He is a corresponding member of the Australian Academy of Science,[12] a member of the American Academy of Arts and Sciences,[13] and a Guggenheim fellow,[14] and has received the Eminent Ecologist Award from the Ecological Society of America.[1] He is a professor emeritus at the University of California Santa Barbara.[15]

Connell was elected to the Australian Academy of Science in 2002 as a Corresponding Fellow.

Research[edit]

Joseph H. Connell did many researches in the field of ecology. His numerous researches gave a solid background in understanding ecology today. Connell is known as the first scientist to test hypothesis about tropical diversity.[16] Much of his studies are focused on determining community structure that are based on physical factors, actions and interaction of species that are involved in competition, predation, and recruitment.[17]

Connell’s paper on “Diversity in tropical rain forests and coral reefs” had made it clear that disturbance have a crucial impacts on the ecological communities.[18] This article discuss the organization and assemblages of two competing species that is coral reefs and tropical rain forest. He explored that trees in the tropical rain forest and coral reefs are in non-equilibrium state, and if they are not disturbed, then they will progress towards low-equilibrium diversity community.[18]

Besides this paper he wrote other numerous papers in proving existing evidence and trying to make the concepts clear that explains the structure of communities, different patterns of successions and species biodiversity.[17] Connell is not only a great ecologist researcher but he is also a great teacher, and a mentor. As a teacher he encourages his students to go beyond and look beneath the surface and evaluate the ecological matter. As a mentor, he is very eager to discuss ecological concepts with his undergraduate students, and help them in their work.[17] Overall, Connell have supported ecology with his great work. Thus, for all of his hard work he had received awards such as George Mercer Award in 1963.[1] and Eminent Ecologist Award form Ecological Society of America.[17]
