Monique Clergue-Gazeau


"The death of Monique Clergue-Gazeau in the year 2000 has brought almost to an end, hopefully only temporarily, a distinguished record of simuliid studies in France since World War 2 - starting with Paul Grenier at the Institut Pasteur in Paris in the 1940s and 1950s, followed by Jean-Marie Doby at the University of Rennes and Auguste Dorier at the University of Grenoble in the 1950s and 1960s, and continuing most recently with Françoise Beaucournu-Saguez of Rennes (died 2000, see Bulletin 16: 8–10) and Monique Clergue-Gazeau of the Paul Sabatier University in Toulouse. Beaucournu-Saguez and Clergue-Gazeau carried the flame for simuliidology in France from the mid-1970s almost to the present time and their loss is a blow to blackfly studies in general; they spread their taxonomic and faunal nets wider than their home territories and published valuable works embracing not only simuliids in France but also North Africa and parts of the Middle East. Luckily, Jean Giudicelli of Marseille, though formally retired, remains in harness continuing his studies on the blackflies of Morocco and Lebanon. Monique Gazeau was born on 20th November 1931. In the manner common in France, she added her husband's name Clergue upon her marriage. Throughout her professional life she was associated with the Centre National de la Recherche Scientifique, to which she was affiliated as a research fellow in October 1964. She was not part of the teaching faculty and thus was able to devote her time to biological research, attached to the Laboratoire d'Hydrobiologie of the Paul Sabatier University in Toulouse. Over several years she alternated her life between the out-station laboratory of the C.N.R.S. located in the foothills of the Pyrenees at the village of Moulis, whence her fieldwork in the mountains could be easily undertaken, and her permanent base in Toulouse, where she returned when in need of full-scale university facilities to bring her field studies to publication. Monique C.-G.'s early biological research was on the urodele Amphibia, her specialist student thesis (1963) providing a comparative study of lake and cave-dwelling species, and her doctoral thesis (1972) being on the reproductive and developmental life of the cavernicolous species of these amphibians in the Pyrenees. These studies were a far cry from her later involvement with the Simuliidae. That came about in 1983 at a time when the laboratory to which she was attached decided upon a change of direction in its research thrust and needed someone to specialise in this family of benthic insects. It was this change which, fortunately for everyone interested in the Simuliidae of the western palaearctic area, brought M. C.-G. into the fold of blackfly research. The Simuliidae, one could say, were wished upon her, but she became deeply committed to this family and between 1985 and 1993 published (sometimes with colleagues) a dozen significant papers. Of these one should highlight her important keys to the simuliids of the Pyrenees9, a work based largely on her own fieldwork. In another direction, notable works are those resulting from her investigations on the impact of hydro-electric dams on the lotic fauna3,5 The 1980s was a busy time in France for collaborative projects with students from countries under erstwhile French influence, and Monique C.-G. became drawn to an interest in the circum-Mediterranean simuliid fauna, coauthoring papers on blackflies in Lebanon1 and North Africa 2,4,10 but not personally collecting in these areas. She did, however, visit Tunisia to be part of the thesis jury for Moncef Boumaiza, a colleague with whom she wrote two of her papers2,4. Her last publications, in 199311,12, were with Dr Gilles Vinçon, a close colleague in hydrobiology. Through all these activities her interest in vertebrate biology never waned and we have learned that through her latter years she continued to participate in studies on reptilian embryology! Monique Clergue-Gazeau was a person of great kindness who was always specially helpful to her younger colleagues, supremely honest in all matters, and never for long discouraged by the setbacks she encountered. She retired on 1st January 1992. Sadly, soon after the death of her husband in a car crash in 1999, she fell victim to bone cancer".

she was especially a great herpetologist and she published several articles that also nowadys contitute a miliar stone for the knowledge of the ecology, the ethology and the conservation of trogloxens and troglophilous urodels.
