The fields of study he is best known for: Ecology IUCN Red List Gene The scientist’s investigation covers issues in Zoology, Ecology, Genetics, Canis and Mitochondrial DNA. Ettore Randi has researched Zoology in several fields, including Genetic variability and Phylogenetics. His work carried out in the field of Ecology brings together such families of science as mtDNA control region and Coalescent theory. His study in Genetics is interdisciplinary in nature, drawing from both Population size and Genetic diversity. His biological study spans a wide range of topics, including Italian wolf, Population decline, Biological dispersal and Gene flow. The Mitochondrial DNA study combines topics in areas such as Evolutionary biology, Haplotype and Phylogenetic tree.
