In memoriam: a eulogy for Daniel González-Acuña, 1963-2020

Dr. Daniel González-Acuña was born on February 8, 1963, in San Fernando, central Chile, and became a veterinarian in 1988, at the University of Concepción. Keen on science and wildlife, he did his PhD studies in Germany, at the University of Veterinary Medicine in Hannover (Tierärztliche Hochschule Hannover), receiving his degree in 1997. Professor Eberhard Mey, an expert on lice, was his mentor. His doctoral dissertation was on the ecology and taxonomy of ectoparasites and endoparasites of Chilean birds. When he returned to Chile, he won a faculty position at the University of Concepción as a zoology professor in the School of Veterinary Sciences in Chillán. He spent the rest of his career at the same University, where he became a full professor (Figure 1).

Dr. González-Acuña adored his job, and dedicated himself fully to his profession. He was an outstanding researcher, teacher and mentor. The combination of knowledge and enthusiasm for science demonstrated by Daniel González-Acuña was contagious and attracted undergraduate and postgraduate students to his classes and research laboratory. He mentored more than 100 students: some of them followed his footsteps into science (Alexandra Grandón-Ojeda, Danny Fuentes-Castillo, Lucila Moreno, María Carolina Silva-De La Fuente, Sebastián Llanos-Soto and Sebastián Muñoz-Leal) and are among the authors of this eulogy.

Daniel González-Acuña was a dedicated and tireless nature conservationist. He organized/co-organized numerous workshops and seminars on the subject (32), participated as an expert in numerous committees and gave outreach presentations (50) to diverse audiences, including children. One important milestone in these efforts was the creation of the Wildlife Rehabilitation Center at the University of Concepción, which currently admits around 200 cases per year. Since its creation in 2004, the Center has provided veterinary attention to a number of wildlife species and has facilitated the recovery of thousands of animals. For his efforts in creating the Wildlife Rehabilitation Center and his constant work for wildlife conservation, Dr. González-Acuña received the “Municipal Heritage Recognition” granted by the Municipality of Chillán in 2017 (Chile) and the “Recognition of the Municipality of Bulnes” in 2019.

Daniel was born a naturalist. He loved to explore nature, which led him to do extensive fieldwork in both continental and insular terrains in Chile and South America, including the Antarctic Peninsula. Daniel was a recognized ornithologist. He documented diverse aspects of the natural history of Chilean birds. Since 2016, Daniel had been the Editor-in-Chief of the Revista Chilena de Ornitología (Chilean Journal of Ornithology). His arduous dedication and close interaction with associate editors, reviewers and authors contributed to raising the standard and increasing the visibility of the journal.

As a parasitologist, Daniel showed a genuine interest in almost all terrestrial fauna. His contributions encompassed an extremely broad spectrum of subjects, ranging from his favorite ectoparasites (mites, fleas, lice and ticks) to helminths and blood sporozoans from Chilean vertebrates, including work on disease vector biology. During his academic life, Daniel achieved amazing scientific productivity. He authored 301 scientific papers, two books and 23 book chapters, and made 338 presentations at national and international conferences. His publications included descriptions of several novel parasite species, including 30 mites, 11 fleas, five ticks and four lice. Daniel’s scientific research was funded primarily by seven major projects: four by the Chilean National Science and Technology Fund (FONDECYT); two by the Chilean Antarctic Institute (INACH); and one by the Scientific and Technological Equipment Fund (FONDEQUIP). It is reasonable to say that he was one of the most influential contemporary researchers on this topic, not only in Chile but also throughout Latin America. Daniel was always open to collaborate in other interdisciplinary projects on wildlife toxicology, Antarctic science, genetics, one health and so on. His scientific work obtained national recognition through the “Dr. Álvaro Blanco B. Award” (2013) given by the Chilean Veterinary Medical College, and the “Award for a scientific career” (2016) given by the University of Concepción to the 10 faculty members with the highest scientific productivity over the last 20 years.

Daniel González-Acuña's research and recognition were not restricted to Chile. He collaborated widely with biologists and veterinarians, including ectoparasitologists, helminthologists and vector biologists in South America, Australia, France, Germany, New Zealand, Poland, Russia and the United States. These studies, often tackling broader questions, earned Daniel international recognition.

Although Daniel was interested in endoparasites and ectoparasites in general, he had a particular interest in ticks. In July 2003, he and colleagues from South America congregated at the Butantan Institute in São Paulo, to participate in the first International Course on Tick Taxonomy of the Neotropical Region. Daniel, who worked as a professor of zoology, was among the most motivated participants. Acarology became one of his central topics of research for the rest of his career. Fruitful scientific collaboration and friendship with the colleagues he met in São Paulo was another milestone of his research life. His role was particularly instrumental in collaborations with tick experts in Argentina and Uruguay, who greatly benefited from Daniel’s motivation, and from his ability to conduct fieldwork in harsh environments and find rare tick specimens (González-Acuña et al. 2018González-Acuña D, Saracho-Bottero MN, Ossa G, Guglielmone AA, Nava S. Ixodes chilensis Kohls, 1956 (Acari: Ixodida: Ixodidae): re-description of the female, description of the nymph, and phylogenetic position inferred from mitochondrial DNA sequences of the 16S rRNA gene. Syst Parasitol 2018; 95(8-9): 959-967. PMid:30155597.

Daniel González-Acuña passed away on December 28, 2020, in Rancagua (central Chile). His departure is especially distressing because the scientific community and his students not only lost a wonderful scientist, colleague or mentor. Many lost a friend. Daniel was an extremely engaging, open and friendly person, which resulted in many of his international colleagues becoming close friends and joining him in different expeditions in Chile and abroad. Besides his research-related travel and expeditions, Daniel was an outdoorsman and a true globetrotter. He visited all continents and was an extremely avid, outstanding mountaineer who ascended some of the tallest peaks on Earth. He was also an active marathon runner, completing numerous races in Chile and abroad, and an experienced wildlife photographer. Daniel was always willing to share his stories with his closest friends. Hundreds of short letters narrating his travels were spread by him during his career (Suppl. 1).

Without any doubt Daniel González-Acuña’s outstanding work marked a significant phase in the studies of parasites in Chile and Latin America. We are convinced that his scientific endeavor constitutes a benchmark for both colleagues and emerging young parasitologists. We will always be thankful for all the special moments we shared with him, and his legacy as an exceptional researcher and as a person will live in our minds and hearts forever.
