Estimating the magnitude and sensitivity of energy fluxes for stickleback hosts and Schistocephalus solidus parasites using the metabolic theory of ecology

open access: yesEcology and Evolution, Volume 13, Issue 12, December 2023., 2023
While parasites are ubiquitous across ecosystems, their effects on host energy flow (and thus broader ecological implications) are difficult to quantify and generalize across species. In this study, we estimated host–parasite energy flux to build upon fundamental ecological theory and develop capacity for utilizing this common‐currency approach across ...

Parasites indicate trophic complexity and faunal succession in restored oyster reefs over a 22‐year period

open access: yesEcological Applications, Volume 33, Issue 4, June 2023., 2023
Abstract Foundation species like the eastern oyster (Crassostrea virginica) create complex habitats for organisms across multiple trophic levels. Historic declines in oyster abundance have prompted decades of restoration efforts. However, it remains unclear how long it takes for restored reefs to resemble the trophic complexity of natural reefs.

Within‐host and external environments differentially shape β‐diversity across parasite life stages

open access: yesJournal of Animal Ecology, Volume 92, Issue 3, Page 665-676, March 2023., 2023
The results of this study provide key data for the comparison of community‐level processes where adult and immature stages inhabit vastly different habitats, whether this be parasites (e.g. adult and larval nematodes) or free‐living organisms (e.g. adult and larval amphibians).

Diversity and community ecology of metazoan parasites in Pimelodus ornatus (Siluriformes: Pimelodidae) from the Amazonas River in Brazil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2021
The present study investigated the metazoan parasite community in Pimelodus ornatus from the Amazon River, in the state of Amapá (Brazil). Of 71 fish examined, 70.4% were parasitized by Demidospermus sp.

Weighing the predictors: host traits and coinfecting species both explain variation in parasitism of Rock Ptarmigan

open access: yesEcosphere, Volume 12, Issue 8, August 2021., 2021
Abstract Testing hypotheses in ecological and evolutionary parasitology can require testing whether host traits or coinfecting parasites explain variation in parasitism by focal species. However, when host traits and coinfecting parasites are considered separately, relations between either and parasitism by focal species can be spurious—a problem that ...

Important questions to progress science and sustainable management of anguillid eels

open access: yesFish and Fisheries, Volume 22, Issue 4, Page 762-788, July 2021., 2021
Abstract Anguillid eels are found globally in fresh, transitional and saline waters and have played an important role in human life for centuries. The population status of several species is now of significant concern. The threats to populations include direct exploitation at different life stages, blockages to migratory routes by dams and other ...

Infracommunity dynamics of chiggers (Trombiculidae) parasitic on a rodent

open access: yesParasitology, 2015
SUMMARYWe studied the structure of chigger mite (Trombiculidae) communities parasitic on a South African rodent, Rhabdomys pumilio. We aimed to determine whether: (a) different chigger species differ in preferences for certain body areas of a host and (b) chigger assemblages among body areas of the same host individual, are structured and if so ...

Structure of the parasite infracommunity of Sciades proops from the Japaratuba River Estuary, Sergipe, Brazil [PDF]

open access: yesBrazilian Journal of Biology, 2015
Abstract The catfish species Sciades proops inhabits muddy estuaries and shallow brackish lagoons, as well as freshwater. For these reasons, it is believed that this species may act as an intermediate, definitive and paratenic host in the life cycle of many parasites. From November 2010 to November 2011 and from August 2012 to July 2013, a total of 126

Parasite infracommunity diversity in eels: a reflection of local component community diversity

open access: yesParasitology, 2003
The intestinal macroparasite communities of freshwater eels (Anguilla anguilla) captured in the south of England from Windsor (River Thames) during August 2001, and Leckford (River Test) during late June/July 2000, are reported for the first time. Parasite component communities were among the most species rich and diverse recorded from European eels. A
