Malcolm L. McCallum(born December 26, 1968[1]) is an Americanenvironmental scientist,conservationist,herpetologist,andnatural historianand is known for his work on theHolocene Extinction.He is also a co-founder of the herpetology journal,Herpetological Conservation and Biology.[2]He is a key figure in amphibian biology and his research has produced numerous landmark studies.[3]His work has been covered byDavid Attenborough,[4]Discover Magazine,[5]and other media outlets.

Education, research, teaching and service[edit]

McCallum was born in Maywood, Illinois. He earned hisBSwith a double major inagricultureandbiologyfromIllinois State University,[6][circular reference].He earned aMSinEnvironmental BiologyfromEastern Illinois University[7]and thePhDdegree inEnvironmental SciencefromArkansas State University,specializing inecotoxicologyandconservation ecology.He is notable alumni from all three universities.[8][9][10][11]He has been ranked among the 150 most influential environmental scientists[12]and in the top 200 american zoologists.[13]

In 1997 his discovery of deformed frogs in Madison County, Illinois[14]received media coverage in St. Louis news outlets.[15]He then worked at the St. Louis Children's Aquarium as the institution's grant writer, and designed educational programs, conducted research on the use ofbovine somatotropin(bST) applications in aquaculture, and delivered tours and extension programming until he left to pursue his PhD in 1999. He also organized and edited the First International Symposium on the conservation and sustainability of the ornamental fish industry on Rio Negro River, Manaus.[16]He participated in several areas of research that later were published by the aquarium[which?]from 1999-2001.[17][failed verification]Stanley E. Trauthwas his doctoral mentor.

Many of his early papers were focused onnatural history,but they also cover amphibian conservation, ecological immunology, and general biology. He is widely published on the life history and conservation ofBlanchard's cricket frog(Acris blanchardi) with papers on its systematics, immunology, behavior, life history, and conservation needs. He continued this research as an assistant professor atLouisiana State University at Shreveportfrom 2003–2005.

In 2006 McCallum and several other scientists established the journalHerpetological Conservation and Biology.

He moved toTexas A&M University Texarkanain 2005. Here, he developed a novel teaching method for classroom discussions. "The result of this model was not only to circumvent many lazy student behaviors, but also to improve reading comprehension by familiarizing students with how to read, process, and evaluate complex scientific manuscripts in a short period of time." Hedwig Pöllöläinen.[18]

McCallum usedfuzzy logicin his paper,Amphibian decline or extinction? Current losses dwarf background extinction rates,[19]to compare recent extinction rates of amphibians to their rates at the k-Pg boundary. His calculations demonstrated that the losses in amphibian biodiversity in recent times represented one of the most rapid losses in biodiversity ever observed. In 2008 the study was listed byDiscover Magazineas #4 among ten "landmark papers" on the topic ofamphibian extinctions and declines.[20]His use of fuzzy approaches was extended to two studiesaddressing climate changeimpacts on herpetofauna.[21][22]His 2015 paper argued that species losses of vertebrate animals since 1980 have been faster that the Cretaceous–Paleogene extinction event that wiped out dinosaurs 65 million years ago, suggesting we are in a 6th mass extinction.[23][24]

In 2014 he conducted a study usingGoogle Trendsto data mineGooglesearch data to infer public interest on the environment, and concluded that interest in the environment had fallen since 2004.[25]In 2019, he compared Google searches before and after release of the landmark encyclical,Laudato Si',revealing that interest in the environment rose markedly in most countries around the world.[26][27]
