An Efficient Numerical Scheme for Fractional Host–Parasite Hyperparasite Interaction Model

open access: yesApplied Mathematics in Science and Engineering
In this paper, we analyse the unique characteristics of hyperparasites and discharge incidents in the initial stage of parasite populations. If hyperparasites are effectively developed in a population, they can play a crucial role in controlling host ...

A novel fungal hyperparasite of Puccinia striiformis f. sp. tritici, the causal agent of wheat stripe rust. [PDF]

open access: yesPLoS ONE, 2014
Puccinia striiformis f. sp. tritici (Pst), the causal fungus of wheat stripe rust, was previously reported to be infected by Lecanicillium lecanii, Microdochium nivale and Typhula idahoensis. Here, we report a novel hyperparasite on Pst.

Hyperparasitism by helminths: new records of cestodes and nematodes in proteocephalid cestodes from South American siluriform fishes Hiperparasitismo por helmintos: novas ocorrências de cestóides e nematóides em cestóides proteocefalídeos de peixes siluriformes da América do Sul [PDF]

open access: yesMemorias do Instituto Oswaldo Cruz, 1989
Proteocephalid cestode hyperparasite are reported from numerous proteocephalids occurring in pimelodid fishes in different regions of Brazil. In addition, three specimens of a nematode hyperparasite are reported from the proteocephalid cestode ...

Impact of climate on a host–hyperparasite interaction on Arabica coffee in its native range

open access: yesJournal of Applied Ecology, Volume 61, Issue 3, Page 538-550, March 2024.
Our findings highlight that coffee leaf rust and its hyperparasite are both affected by shade cover and temperature, but in different ways. On the one hand, these niche differences lead to the worrying prediction that levels of coffee leaf rust will increase, and its hyperparasite will decrease, with climate change.

Ecological Functions of Zoosporic Hyperparasites

open access: yesFrontiers in Microbiology, 2014
Zoosporic parasites have received increased attention during the last years, but it is still largely unnoted that these parasites can themselves be infected by hyperparasites.

Parasites of the hermit crab Pagurus hirsutiusculus; distribution, prevalence, and thermal ecology. [PDF]

open access: yesPLoS ONE
Parasites are common throughout the biosphere and can play significant ecological roles. However, most parasites are understudied, particularly with regards to how their prevalence and impacts vary with environmental conditions.

Biomathematical enzyme kinetics model of prebiotic autocatalytic RNA networks: degenerating parasite-specific hyperparasite catalysts confer parasite resistance and herald the birth of molecular immunity. [PDF]

open access: yesPLoS Computational Biology
Catalysis and specifically autocatalysis are the quintessential building blocks of life. Yet, although autocatalytic networks are necessary, they are not sufficient for the emergence of life-like properties, such as replication and adaptation.

Original observations of Desmozoon lepeophtherii, a microsporidian hyperparasite infecting the salmon louse Lepeophtheirus salmonis, and its subsequent detection by other researchers [PDF]

open access: yesParasites & Vectors, 2011
A microsporidian hyperparasite, Desmozoon lepeophtherii, of the parasitic copepod Lepeophtheirus salmonis (salmon louse), infecting farmed Atlantic salmon (Salmo salar), was first discovered in the west of Scotland in 2000.
