2004 - Fellow of the Royal Society, United Kingdom
The scientist’s investigation covers issues in Sperm, Zoology, Sperm competition, Ecology and Sexual selection. His Sperm research incorporates elements of Evolutionary biology, Passerine and Semen. His Zoology research includes themes of Anatomy and Internal fertilization.
His Sperm competition study combines topics from a wide range of disciplines, such as Sperm heteromorphism, Extra-pair copulation and Reproductive success. His work in the fields of Ecology, such as Plumage, Predation, Seasonal breeder and Animal ecology, intersects with other areas such as Taeniopygia. His Sexual selection study incorporates themes from Mate choice, Mating preferences, Selection, Reproduction and Competition.
His primary areas of investigation include Zoology, Sperm, Ecology, Sperm competition and Sexual selection. His work on Mating, Mating system and Mate guarding as part of general Zoology study is frequently linked to Taeniopygia, bridging the gap between disciplines. Tim R. Birkhead has researched Sperm in several fields, including Evolutionary biology, Sperm heteromorphism, Anatomy and Reproduction.
His study in Passerine, Competition, Animal ecology, Seabird and Ecology is carried out as part of his studies in Ecology. Tim R. Birkhead interconnects Sperm motility, Extra-pair copulation and Human fertilization in the investigation of issues within Sperm competition. His Sexual selection research integrates issues from Intraspecific competition, Mate choice, Selection and Reproductive success.
Zoology, Ecology, Sperm, Geography and Uria aalge are his primary areas of study. As a part of the same scientific study, Tim R. Birkhead usually deals with the Zoology, concentrating on Incubation and frequently concerns with Hatching. His study in the field of Ecology also crosses realms of Term, Taeniopygia and Brain size.
Tim R. Birkhead carries out multidisciplinary research, doing studies in Taeniopygia and Passerine. Oviduct is closely connected to Human fertilization in his research, which is encompassed under the umbrella topic of Sperm. Tim R. Birkhead studies Sperm competition, focusing on Female sperm storage in particular.
Tim R. Birkhead mostly deals with Zoology, Ecology, Sperm, Human fertilization and Sperm competition. His work deals with themes such as Instinct, Genealogy and Selection, which intersect with Zoology. In the subject of general Ecology, his work in Uria aalge, Seasonal breeder, Pair bond and Evolutionary transitions is often linked to Term, thereby combining diverse domains of study.
His study looks at the relationship between Sperm and fields such as Sperm heteromorphism, as well as how they intersect with chemical problems. His studies deal with areas such as Oviduct and Female sperm storage as well as Human fertilization. Tim R. Birkhead performs multidisciplinary study on Sperm competition and Taeniopygia in his works.
