Life is too short to be serious all the time: Donald Duck presents unconventional motivations for publishing in academia
No full textIn this food for thought article, we introduce the ‘Donald Duck Phenomenon’ to consider ten unconventional reasons for publishing in academia. These include (i) symbolic immortality, (ii) personal satisfaction, (iii) a sense of pride, (iv) serious leisure, (v) cause credibility, (vi) altruism, (vii) collaboration with a friend or family member, (viii) collaboration with a hero, (ix) conflict or revenge, and (x) for amusement. The article was inspired by the lead author’s social media search for a co-author with the surname ‘Duck’. Through LinkedIn, the lead author, Associate Professor William E. Donald, who is based in the UK and specialises in Sustainable Careers and Human Resource Management, found a collaborator, Dr Nicholas Duck, based in Australia and specialises in Organisational Psychology. While the collaboration may appear somewhat ‘quackers’, per one of Donald Duck’s famous phrases, “Life is too short to be serious all the time, so if you can’t laugh at yourself then call me… I’ll laugh at you, for you”. We hope that this article offers some interesting insights, particularly for academics at the start of their scholarly journey, and acts as a way to stimulate conversation around unconventional reasons for publishing in academia
Corrigendum: Revision of the Name \u3ci\u3eEimeria palustris\u3c/i\u3e Hertel and Duszynski, 1987, from Shrews (\u3ci\u3eSorex\u3c/i\u3e spp.)
No full textIn the paper on shrew coccidians that appeared in the February 1987 issue of the Journal (Hertel and Duszynski, 1987, Journal of Parasitology 73: 172-183) we named one of our new species Eimeria palustris. Dr. N. D. Levine (University of Illinois) kindly informed us that the name E. palustris is preoccupied by an eimerian described from the rice rat, Oryzomys \u3epalustris (Barnard, Ernst, and Stevens, 1971 , Journal of Parasitology 57: 1,293-1,296). We would like to rename the form we saw Eimeria longirostris for the specific name of the host in which the species was most prevalent
Revisiting the Code: Clarifying Name-Bearing Types for Photomicrographs of Protozoa
No full textIn 1988, Bandoni and Duszynski argued that individuals involved in the taxonomy and systematics of the coccidia should become familiar with the 3rd edition of the Code of Zoological Nomenclature (Ride et aI., 1985) and tried to reiterate the importance and utility of designating some form of type specimens and archiving them in appropriate museums. Their intent was to create an awareness among biologists working with coccidia (or other protists) of the value of designating type specimens. In the decade since their admonition, bench scholars working with coccidia, and journal editors to whom they submit their work, have begun to endorse the type concept by requiring that some form of type specimen be submitted before new species names and descriptions are published. Although some authors still submit samples of oocysts preserved in standard fixatives (for reasons why this option is less than optimal, see Duszynski and Gardner [1991]), the majority submit photomicrographs of sporulated oocysts as their type species to various accredited museums. The issue that arises is what to call these kinds of type specimens.
Proposed here is to add the prefix photo- to appropriate terminology already sanctioned by the Code to help clarify existing terminology. Because increasing numbers of photomicrographs are being submitted to accredited museums to archive new species, there seems a need for precise definitions, so those who submit photomicrographs of sporulated oocysts and/or other life cycle stages of coccidia will know, unambiguously, how to define their name-bearing type specimen
Polymorphism of Eimerian Oocysts: A Dilemma Posed by Working with Some Naturally Infected Hosts
No full textMorphological variation of sporulated oocysts within individual eimerian species is well documented (Joyner, 1982. In Biology of the Coccidia, P. L. Long (ed.). University Park Press, Baltimore, pp. 35-62). In some cases, oocysts of a single eimerian species are known to vary in size by as much as 40% during patency (Duszynski, 1971, Journal of Parasitology 57: 948-952). During a survey to determine the prevalence of coccidiosis in sandhill cranes (Grus canadensis) wintering in New Mexico (Parker and Duszynski, 1986, Journal of Wildlife Diseases 21: 25-35), marked polymorphism was observed among sporulated oocysts of Eimeria reichenowi. Oocysts were obtained from intestinal contents of cranes necropsied in the field and processed for study by routine sporulation and flotation techniques (Duszynski et al., 1982, Journal of Parasitology 68: 1,146-1,148). Initially, oocysts were categorized into 5 groups based on obvious qualitative/quantitative features including oocyst wall texture, appearance of the sporocyst residuum, and the number of polar bodies. Fifty-seven of 118 (48%) fecal samples with E. reichenowi contained 2 or more morphological types of oocysts. Oocysts were measured under oil immersion (100 x Neofluar objective, Zeiss Universal Photomicroscope) and differences between the 5 oocyst groups were tested for significance (P \u3c0.05) using the Student-Newman-Keuls procedure
