Biodiversity in helminths and nematodes as a field of study: an overview

  title={Biodiversity in helminths and nematodes as a field of study: an overview},
  author={Jean-Pierre Hugot and Pierre Baujard and Serge Morand},
Despite their potential negative effects, parasites may be used as targets for biological conservation and studies on the evolutionary and ecological impact of parasitism. These purposes serve to increase our knowledge on the species diversity of parasites. In the present paper we try to precisely define the composite zoological group currently designated as 'helminths' and to address the question of how many known species there are in the different clades of parasitic worms, as compared with…

Describing Parasite Biodiversity: The Case of the Helminth Fauna of Wildlife Vertebrates in Mexico
Parasites have, according to Brooks & Hoberg (2006), a dual and conflicting significance because they may regulate host populations, playing a central role in maintenance of genetic diversity and structuring host communities and, at the same time, they represent treats to human health, agriculture, natural systems, conservation practices, and the global economy.
Diversity of helminth parasites in aquatic invertebrate hosts in Latin America: how much do we know?
The knowledge is still too scarce to allow any zoogeographical or helminth diversity generalization, as most hosts have been studied locally and the studies on invertebrate hosts in LAC are substantially uneven among countries.
Research on helminths from Mexican amphibians: gaps, trends, and biases
An analysis of helminthological studies in Mexico evidenced gaps and biases on research efforts that have been devoted to relatively few host species, regions, and approaches, and provides guidelines to improve research on helminths parasitizing amphibians.
Metacommunity Structure of Helminths of Necromys Lasiurus (Rodentia: Sigmodontinae) in Different Land Use Areas in the Brazilian Cerrado
A checkerboard structure of metacommunity was found on the infracommunity scale, which suggests the existence of interspecific competition and most species were influenced by the same environmental gradient and that the species-poor communities were subsets of species-rich communities.
Introductory Chapter: Helminthes Diversity - Focus on Nematodes
Parasitic helminthes are worms of great medical and veterinary importance. They include the Nematodes (Roundworms) and the Platyhelminthes (Flatworms) which consist of the Trematodes (Flukes) and
Usefulness of morphological data for the study of nematode biodiversity
Electronic publication according to the Code of Zoological Nomenclature would be one solution, but journals and authors seem reluctant to accept it, and a variant would be to publish on paper only the diagnosis of the new species.
Molecular Diversity of Nematode Parasites in Afrotropical Reed Frogs (Hyperolius spp.)
The findings suggest that nematode diversity is probably lower than previously assumed due to low host specificity, and data facilitate molecular identification of adult and specifically larval nematodes found in amphibians of Sub-Saharan Africa.
Biogeography, humans, and their parasites
This chapter aims to summarize some of the recent advances in the evolutionary and ecological relationships between humans and their pathogens, and reinvestigate the geography of human parasites and the geometry of human defences.
Taxonomy of Plant Parasitic Nematodes in Global Context vis-ÃÂ -visIndia
About 631 phytoparasitic species belonging to 56 genera under Tylenchida have been reported from India; it is nearly one-third of the total known plant parasitic nematodes around the world.
Diversity and prevalence of gastrointestinal parasites in two wild Galago species in Gabon.


A molecular evolutionary framework for the phylum Nematoda
It is suggested that animal parasitism arose independently at least four times, and plant parasitism three times, which indicates that convergent morphological evolution may be extensive and that present higher-level classification of the Nematoda will need revision.
Nematode systematics: past, present and future.
The future of nematode taxonomy will depend on the funding opportunities provided by national and international authorities and molecular techniques have made systematics again exciting; when combined with the more traditional morphological approach, they will lead to new insights.
Primates and their pinworm parasites: the cameron hypothesis revisited.
A morphologically based cladistic analysis of the Enterobiinae allows a reevaluation of the Cameron's hypothesis of close coevolution with cospeciation between hosts and parasites and confirms the subgroups previously described in the subfamily and supports its aspect of association by descent.
Patterns and processes in the evolution of animal parasitic nematodes
With this dataset, the Strongylida is placed as a monophyletic clade nested within the Rhabditina, and the Ascaridida, Oxyurida and Spirurida are closely related, but currently have no clear closest free-living sister taxon.
Parasites as probes for biodiversity.
This work urges the planners of biodiversity preserves in the neotropics to consider the Yungas of Bolivia as a region that supports an ancient ecological community worthy of consideration as a biopreserve.
Genisys and computer-assisted identification of nematodes.
The functionality of a general identification system that could overcome the problems and difficulties encountered in the use of computerised tools is described, which would include a general database with all the characters from all the published descriptions of nematodes species and a set of integrated identification tools.
Phylogenetic analysis of the higher classification of the Nematoda
Characters upon which various versions of the classification of Nematoda are based are examined to identify plesiomorphic and derived character states and these are used to construct a phylogenetic tree using the Wagner algorithm.
Determinants of parasite species richness in Mediterranean marine fishes
It is shown that fish body size was not correlated with geographical range when using phylogenetic independent contrasts, and it is suggested that studying parasites of host species from the same geographical region avoids the problem of confounding various assemblages of hosts with distinct histories.
Comparisons suggest that only host body size can be an important determinant of parasite community richness in certain host groups, and the need to control for phylogeny in investigations of host-parasite interactions is illustrated.
Pinworms and Primates: A Case Study in Coevolution
Cladistic analysis of 13 species of Enterobius based on 31 morphological characters supports the notion that pinworms and primates have co-speciated and reexamined the problem based on study of available type material and concluded that Cameron had been correct in his assessment.
