Rebecca Yahr is an American lichenologist who works at the Royal Botanic Garden Edinburgh in Scotland. She was President of the British Lichen Society from 2019 until 2022.[1]

Early life and education[edit]

Rebecca Yahr was born in the United States and grew up near the Appalachian Mountains.[2] She studied botany at University of California, Davis for her B. Sc. degree, awarded in 1994.[3] She gained her doctorate from Duke University in 2004 for research into how the relationship between the fungi and algae within a lichen evolve over time.[3]

Career[edit]

From 1991 until 1998 Yahr worked as a botanical research scientist, firstly for the California Native Plant Society and then at Archbold Biological Station in Florida, USA, where she began to be interested in lichens.[3][4] In 2005 she took up a research fellowship at the University of St Andrews in Scotland, UK and from 2006 has worked at the Royal Botanic Gardens, Edinburgh in Scotland.[5][6] Her research concerns the evolution of lichens. She uses historical data and specimens, biogeography and molecular biology.[7] She also studies the processes that underlie the lichen symbiosis.[1]

From 2020 she has been the co-chair of the International Union for Conservation of Nature (IUCN) Lichen Specialist Group.[8] She contributes samples to the Darwin Tree of Life Project.[9]

Yahr collaborated in the characterisation of Opegrapha viridipruinosa Coppins & Yahr (renamed Alyxoria viridipruinosa (Coppins & Yahr) Ertz)[10] and Phaeographis illitoraticola Lendemer, R.C. Harris & Yahr (now Phaeographis atromaculata (A.W.Archer) A.W.Archer).[11]

She is the author or co-author of over 45 scientific publications and several book chapters. These include:

Awards[edit]

From 2019 until 2022 she was President of the British Lichen Society.[3] The lichen species Gyalectidium yahriae was named after her in 2000.[12]

In October 2023 the Systematics Association invited Yahr to give the society's annual Founders Lecture.[13]

Personal life[edit]

Yahr is married to ecologist Chris Ellis and they have two children together.[3]
