Christopher N. Johnson mostly deals with Ecology, Biodiversity, Extinction, Predation and Dingo. His study in Megafauna extends to Ecology with its themes. His Biodiversity research is multidisciplinary, incorporating elements of Trophic level, Abundance, Generalist and specialist species and Ecosystem.
His work carried out in the field of Extinction brings together such families of science as Rare species and Arboreal locomotion. Within one scientific family, Christopher N. Johnson focuses on topics pertaining to Invasive species under Predation, and may sometimes address concerns connected to Prescribed burn, Resource, Ecosystem management and Fire ecology. His study in the field of Canis lupus dingo is also linked to topics like Cost effectiveness.
His primary scientific interests are in Ecology, Predation, Habitat, Extinction and Zoology. The study of Ecology is intertwined with the study of Megafauna in a number of ways. As a part of the same scientific study, he usually deals with the Predation, concentrating on Wildlife and frequently concerns with Livestock.
He focuses mostly in the field of Habitat, narrowing it down to topics relating to Foraging and, in certain cases, Sarcophilus. Christopher N. Johnson studied Zoology and Biological dispersal that intersect with Bettong. His study in Biodiversity is interdisciplinary in nature, drawing from both Wildlife conservation and Ecosystem.
Ecology, Predation, Extinction, Threatened species and Mesopredator release hypothesis are his primary areas of study. Ecology is closely attributed to Megafauna in his research. His biological study spans a wide range of topics, including Zoology, Sarcophilus and Invasive species.
His Threatened species research also works with subjects such as
Christopher N. Johnson spends much of his time researching Ecology, Mesopredator release hypothesis, Predation, Introduced species and Threatened species. Much of his study explores Ecology relationship to Extinction. His Introduced species research integrates issues from Zoology, Population decline, Prey switching and Wildlife.
His work carried out in the field of Threatened species brings together such families of science as Protected area, Mammal, Fishery and Invasive species. His Biodiversity study combines topics from a wide range of disciplines, such as Wildlife conservation and IUCN Red List. The study incorporates disciplines such as Carrion, Carnivore and Sarcophilus in addition to Feral cat.
