SummaryMean species richness and diversity of the helminth infracommunity of Apodemus sylvaticus in woodland areas of Co. Down, Northern Ireland, varied in time and space. Variation in infracommunity structure among individual hosts, however, always accounted for more than 60% of the variation in the data from different places or different times ...

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

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

Shedding light on the parasite communities and diet of the deep-sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay). [PDF]
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Factors at multiple scales drive parasite community structure. [PDF]
Beta‐diversity and nestedness may vary with ecological scale, which can reveal important drivers of community assembly and structure. Using parasite communities, the authors demonstrate that failing to account for patterns at one level alters the interpretation of ecological drivers at another.

Divvying up the pie: Tissue nutrient content is related to its parasite load. [PDF]
We investigated how the size and composition of parasitic infracommunities are affected by the nutrient content of their infection sites. We expected infracommunities to be dominated by parasites that were stoichiometrically similar to their infection sites. However, we found that parasites, themselves, can vary in nutrient content and that the size of

Retroviral Infections Affect Survival and Clutch Size of Female Wild Turkeys. [PDF]
We investigated the effects of two oncogenic retroviruses, lymphoproliferative disease virus (LPDV) and reticuloendotheliosis virus (REV), on survival and reproduction of wild turkeys in Maine. REV infection reduced female annual survival by nearly half, while LPDV‐infected hens laid fewer eggs, though other reproductive metrics were unaffected.

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 ...

Haemulids (grunts) represent one of the most diverse families of marine fishes. Even though haemulids are well represented in Mexico along the Pacific and Gulf of Mexico coasts, as well as in the Caribbean Sea, their trematode fauna has been scarcely ...

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.
