“…It is possible to outline the substantial and valuable contributions of some researchers to the development of South American helminthology throughout the 20th century, such as Travassos (1890–1970) and his students, who described several species of helminths, mainly of nematodes and trematodes from freshwater fish in Brazil (Dias et al ., 1990); Thatcher (1929–2011), who published more than 150 papers and several books on helminths and other metazoan parasites of fish from Amazonia (Boeger, 2011); Szidat (1892–1973), who was very important in Argentinian helminthology because, besides his description of more than 60 species, he introduced biogeographic concepts in his studies on fish parasites for the first time in South America (Ostrowski de Núñez, 1994; Choudhury & Pérez-Ponce de León, 2005); Tantaleán and Carvajal, who have increased our knowledge of helminth parasites from fish in Peru and Chile, respectively, and who are still publishing work focused on the taxonomy and ecology of these worms.…”

Helminth parasites of South American fishes: current status and characterization as a model for studies of biodiversity

The South American subcontinent supports one of the world's most diverse and commercially very important ichthyofauna. In this context, the study of South American fish parasites is of increased relevance in understanding their key roles in ecosystems, regulating the abundance or density of host populations, stabilizing food webs and structuring host communities. It is hard to estimate the number of fish parasites in South America. The number of fish species studied for parasites is still low (less than 10%), although the total number of host-parasite associations (HPAs) found in the present study was 3971. Monogeneans, with 835 species (1123 HPAs, 28.5%), and trematodes, with 662 species (1127 HPAs, 30.9%), are the more diverse groups. Data gathered from the literature are useful to roughly estimate species richness of helminths from South American fish, even though there are some associated problems: the reliability of information depends on accurate species identification; the lack of knowledge about life cycles; the increasing number of discoveries of cryptic species and the geographically biased number of studies. Therefore, the closest true estimations of species diversity and distribution will rely on further studies combining both molecular and morphological approaches with ecological data such as host specificity, geographical distribution and life-cycle data. Research on biodiversity of fish parasites in South America is influenced by problems such as funding, taxonomic impediments and dispersion of research groups. Increasing collaboration, interchange and research networks in the context of globalization will enable a promising future for fish parasitology in South America.

Parasitic Crustacea

View full text Add to dashboard Cite

Parasitic Crustacea have been present in scientific literature since Linnaeus introduced the first classification system (binomial nomenclature). Crustaceans are considered to be the most morphologically diverse arthropods, with currently 19 parasitic orders known to science. This chapter reviews the history of discovery for each of the major parasitic Crustacea groups, highlighting some of the key developments that have influenced our current understanding of these parasites. Each taxonomic group is briefly introduced, followed by a synopsis on some of the outstanding contributions within that group. Knowledge development is followed, from the first parasites discovered to other historical highlights that influenced the groups up to this point. Other important discoveries (both taxonomic and ecological) are also noted, serving as a preview to the host-parasite interactions covered in the subsequent chapters. Additionally, several researchers who have added significant contributions to our knowledge of the parasitic Crustacea (specifically in taxonomy and discovery) are introduced, along with photographs of a select few. This historical review of the crustacean parasites provides a background to these diverse and abundant organisms and will contribute to a better understanding of their unique niche in the aquatic environment.
