Metazoan parasite infracommunities of the dusky flounder (Syacium papillosum) as bioindicators of environmental conditions in the continental shelf of the Yucatan Peninsula, Mexico

Parasites & Vectors, 2019
Background We assessed metrics of the metazoan parasite infracommunities of the dusky flounder (Syacium papillosum) as indicators of aquatic environmental health of the Yucatan Shelf (YS) prior to oil extraction.

Endoparasite infracommunities of Hemisorubim platyrhynchos (Valenciennes, 1840) (Pisces: Pimelodidae) of the Baía River, upper Paraná River floodplain, Brazil: specific composition and ecological aspects [PDF]

Brazilian Journal of Biology, 2003
Parasites of 136 specimens of Hemisorubim platyrhynchos, popularly called jurupoca, were analyzed. Fourteen parasite species were recorded: four digeneans (Crocodilicola pseudostoma, one Gorgoderidae species, Sanguinicola platyrhynchi, and ...

Infracommunity level aggregation in the monogenean communities of crucian carp (Carassius carassius)

Parasitology, 2005
Aggregation is one of the distinctive features in parasite-host relationships, which has generally been studied at the level of host communities. Parasite aggregation at the infracommunity level may nevertheless be important for intraspecific interactions such as parasite mating success and opportunities for cross-fertilization.

Metazoan endoparasites of Brycon orbignyanus (Characidae: Bryconinae) in a neotropical floodplain

Acta Scientiarum: Biological Sciences, 2019
Species richness and composition are central themes in community ecology of helminths because they improve the understanding of factors that determine community structure.

Metazoan parasite communities of two deep-sea elasmobranchs: the southern lanternshark, Etmopterus granulosus, and the largenose catshark, Apristurus nasutus, in the Southeastern Pacific Ocean

Parasite, 2018
Two deep-sea shark species were obtained as by-catch of the local fishery of the Patagonian toothfish, Dissostichus eleginoides, at depths ranging from 1000 to 2200 m off central and northern Chile. A total of 19 parasite taxa were found in 133 specimens

Complex interactions within the ectoparasite community of the eastern rock sengi (Elephantulus myurus)

International Journal for Parasitology: Parasites and Wildlife, 2015
Concomitant infection with more than one parasite species is the rule in nature. Since co-infecting parasites are exploiting the same host, interspecific interactions at the infracommunity level are likely. The nature of such interactions can be expected

Host body microcosm and ectoparasite infracommunities: arthropod ectoparasites are not spatially segregated

Parasitology, 2012
SUMMARYWe studied the distribution of ectoparasite species (an ixodid tick, a chigger mite, 7 mesostigmate mites, 5 fleas and 3 lice) on bodies of 5 species of rodent hosts from the marshlands in Argentina to establish whether arthropod ectoparasites are segregated across body parts of the same host individual.

Patterns of species co‐occurrence and density compensation: a test for interspecific competition in bat ectoparasite infracommunities [PDF]

Oikos, 2008
Parasites constitute an ideal system with which to investigate patterns and mechanisms of community structure and dynamics. Nevertheless, despite their prevalence in natural systems, parasites have been examined less often than other organisms traditionally used for testing hypotheses of community assembly. In the present study, we

First study on communities of parasites in Triportheus rotundatus, a Characidae fish from the Amazon River system (Brazil)

Revista Brasileira de Parasitologia Veterinária
This study was the first investigation on the parasites of Triportheus rotundatus, a Characiformes fish from the Amazon, in Brazil. All the fish collected (100%) in a tributary from the Amazon River system were infected by one or more parasite species ...

Parasite infracommunities of Leporinus friderici: A comparison of three tributaries of the Jurumirim Reservoir in southeastern Brazil [PDF]

Anais da Academia Brasileira de Ciências, 2017
The degradation and homogenization of natural habitats is considered a major cause of biotic homogenization. Many studies have been undertaken on the effects of dams on aquatic wildlife, in particular fish assemblages. But how do dams affect the parasitic fauna of such fish?
