Peter Raymond Grant and Barbara Rosemary Grant are a British married couple who are evolutionary biologists at Princeton University. Each currently holds the position of emeritus professor. They are known for their work with Darwin's finches on Daphne Major, one of the Galápagos Islands. Since 1973, the Grants have spent six months of every year capturing, tagging, and taking blood samples from finches on the island. They have worked to show that natural selection can be seen within a single lifetime, or even within a couple of years. Charles Darwin originally thought that natural selection was a long, drawn out process but the Grants have shown that these changes in populations can happen very quickly.
Professor Geoffrey Alan Parker FRS is an emeritus professor of biology at the University of Liverpool and the 2008 recipient of the Darwin Medal. Parker has been called "the professional's professional".
Robin Ian MacDonald Dunbar is a British biological anthropologist, evolutionary psychologist, and specialist in primate behaviour. Dunbar is professor emeritus of evolutionary psychology of the Social and Evolutionary Neuroscience Research Group in the Department of Experimental Psychology at the University of Oxford. He is best known for formulating Dunbar's number, a measurement of the "cognitive limit to the number of individuals with whom any one person can maintain stable relationships".
George Ledyard Stebbins Jr. was an American botanist and geneticist who is widely regarded as one of the leading evolutionary biologists of the 20th century. Stebbins received his Ph.D. in botany from Harvard University in 1931. He went on to the University of California, Berkeley, where his work with E. B. Babcock on the genetic evolution of plant species, and his association with a group of evolutionary biologists known as the Bay Area Biosystematists, led him to develop a comprehensive synthesis of plant evolution incorporating genetics.
Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and these traits are not continuous. The morph phenotype is genetically linked to genes responsible for a unique system of self-incompatibility, termed heteromorphic self-incompatibility, that is, the pollen from a flower on one morph cannot fertilize another flower of the same morph.
Pierre Dansereau was a Canadian ecologist from Quebec known as one of the "fathers of ecology".
Brian Charlesworth is a British evolutionary biologist at the University of Edinburgh, and editor of Biology Letters. Since 1997, he has been Royal Society Research Professor at the Institute of Evolutionary Biology (IEB) in Edinburgh. He has been married since 1967 to the British evolutionary biologist Deborah Charlesworth.
Deborah Charlesworth is a population geneticist from the UK, notable for her important discoveries in population genetics and evolutionary biology. Her most notable research is in understanding the evolution of recombination, sex chromosomes and mating system for plants.
Graham Arthur Charlton Bell is a British academic, writer, and evolutionary biologist with interests in the evolution of sexual reproduction and the maintenance of variation. He developed the "tangled bank" theory of evolutionary genetics after observing the asexual and sexual behaviour patterns of aphids as well as monogonont rotifers.
Andrew Cockburn FAA is an Australian evolutionary biologist who has been based at the Australian National University in Canberra since 1983. He has worked and published extensively on the breeding behaviour of antechinuses and superb fairy-wrens, and more generally on the biology of marsupials and cooperative breeding in birds. His work on fairy-wrens is based around a detailed long-term study of their curious mating and social system at the Australian National Botanic Gardens.
Pontederia crassipes, commonly known as common water hyacinth, is an aquatic plant native to South America, naturalized throughout the world, and often invasive outside its native range. It is the sole species of the subgenus Oshunae within the genus Pontederia. Anecdotally, it is known as the "terror of Bengal" due to its invasive growth tendencies.
Clayton Oscar Person, was recognized internationally as an authority on the genetics of host-parasite relations. He was born and raised in Aylesbury, Saskatchewan, Canada and died in Vancouver, British Columbia, Canada. His writings have made a major contribution to the development of a rigorous theoretical basis for our understanding of how the genetic structure of parasitic populations interacts with that of their host populations. This was known as the gene-for-gene relationship. His theoretical methods have been applied widely in the practical management of parasitic diseases in agriculture and forestry.
Timothy Robert Birkhead is a British ornithologist. He has been Professor of Behaviour and Evolution at the University of Sheffield since 1976.
John P. Smol, is a Canadian ecologist, limnologist and paleolimnologist who is a Distinguished University Professor in the Department of Biology at Queen's University, Kingston, Ontario, where he also held the Canada Research Chair in Environmental Change for the maximum of three 7-year terms (2001–2021). He founded and co-directs the Paleoecological Environmental Assessment and Research Lab (PEARL).
Pauline Yvonne Ladiges is a botanist whose contributions have been significant both in building the field of taxonomy, ecology and historical biogeography of Australian plants, particularly Eucalypts and flora, and in science education at all levels. She is professorial fellow in the School of Botany at the University of Melbourne, where she has previously held a personal chair and was head of the School of Botany at the University of Melbourne from 1992 to 2010. She has been a fellow of the Australian Academy of Science since 2002. The standard author abbreviation Ladiges is used to indicate this person as the author when citing a botanical name.
Judith (Judy) H. Myers is a Canadian-American ecologist. In 2014, she was elected president of the Canadian Society for Ecology and Evolution, and served in that role until 2016. Professor Myers is well known for her decades-long research into plant-animal-microbe interactions, including insect pest outbreaks, viral pathogens of insects, and pioneering work on biological control of insects and plants, particularly invasive species. Throughout her career she has advocated strongly for both the public understanding of science and for increasing the number of women in the STEM subjects: Science, Technology, Engineering, and Mathematics.
Maria R. Servedio is a Canadian-American professor at the University of North Carolina at Chapel Hill. Her research spans a wide range of topics in evolutionary biology from sexual selection to evolution of behavior. She largely approaches these topics using mathematical models. Her current research interests include speciation and reinforcement, mate choice, and learning with a particular focus on evolutionary mechanisms that promote premating (prezygotic) isolation. Through integrative approaches and collaborations, she uses mathematical models along with experimental, genetic, and comparative techniques to draw conclusions on how evolution occurs. She has published extensively on these topics and has more than 50 peer-reviewed articles. She served as Vice President in 2018 of the American Society of Naturalists, and has been elected to serve as President in 2023.
Invasion genetics is the area of study within biology that examines evolutionary processes in the context of biological invasions. Invasion genetics considers how genetic and demographic factors affect the success of a species introduced outside of its native range, and how the mechanisms of evolution, such as natural selection, mutation, and genetic drift, operate in these populations. Researchers exploring these questions draw upon theory and approaches from a range of biological disciplines, including population genetics, evolutionary ecology, population biology, and phylogeography.
Cryptic self-incompatibility (CSI) is the botanical expression that's used to describe a weakened self-incompatibility (SI) system. CSI is one expression of a mixed mating system in flowering plants. Both SI and CSI are traits that increase the frequency of fertilization of ovules by outcross pollen, as opposed to self-pollen.
Loeske E. B. KruukFRS is an evolutionary ecologist who is a Royal Society Research Professor at the University of Edinburgh. She was awarded the 2018 European Society for Evolutionary Biology President's Award. In 2023, she was elected as a Fellow of the Royal Society.
