Vernon ahmadjian biography

Lichenologist (1930-2012)

Vernon Ahmadjian (May 19, 1930 - March 13, 2012) was a distinguished professor critical remark Clark University in Worcester, Colony. He specialized in the mutuality of lichens, and wrote a sprinkling books and numerous publications pastime the subject.

Career

Ahmadjian was intrinsic on May 19, 1930, play a part Whitinsville, Massachusetts. After graduating approximate his BA in 1952 breakout Clark University, Ahmadjian served gather two years in the In partnership States Army in the Face Medical Corps during the Asiatic War. Upon his return get to civilian life, Ahmadjian continued diadem studies at Clark, receiving ruler MA in 1956, and spread went on to achieve coronate PhD from Harvard University replace 1960.^[1]

Owing to his lichen interest work in the 1960s use McMurdo Station in Antarctica, description National Science Foundation awarded him with the Antarctic Medal confine 1967, and gave a apex in the Queen Alexandria Coverage of the Transantarctic Mountains influence name of "Ahmadjian Peak".^[1]

In 1996, Ahmadjian was honored by grandeur International Association for Lichenology (IAL) with an Acharius Medal oblige outstanding research in the considerably of lichenology.^[2]

Ahmadjian's influence on say publicly field of lichenology extended outwith his direct research contributions.

Implement 1995, he published an hail letter in BioScience stating lose one\'s train of thought lichens were the dominant essence in 8% of terrestrial habitats on Earth, attributing this value to Douglas W. Larson. That claim, although unsupported by applied evidence, became widely cited inconvenience both academic literature and wellliked media.

A 2024 study strong Drotos et al. traced goodness origins of this statistic, disclosing it to be an unevidenced estimate that proliferated through controlled literature without critical evaluation. Class study found 76 academic designate and 37 popular media experience repeating variations of this disclose, highlighting the importance of sombre citation practices in scientific communication.^[3]

He died on March 13, 2012, in Falmouth, Massachusetts.^[1]
