Coupling between tolerance and resistance for two related Eimeria parasite species

open access: yesEcology and Evolution, Volume 10, Issue 24, Page 13938-13948, December 2020., 2020
We tested whether closely related parasite species could show different coupling between tolerance and resistance and found a trade‐off between resistance and tolerance to one, Eimeria falciformis, but not to its close relative Eimeria ferrisi. The framework of resistance–tolerance coupling allows to prioritize research questions to be addressed with ...

Genotype-specific vs. cross-reactive host immunity against a macroparasite. [PDF]

open access: yesPLoS ONE, 2013
Vertebrate hosts often defend themselves against several co-infecting parasite genotypes simultaneously. This has important implications for the ecological dynamics and the evolution of host defence systems and parasite strategies.

Partitioning average competition and extreme-genotype effects in genetically diverse infections [PDF]

open access: yes, 2008
Competition between parasite genotypes in genetically diverse infections is widespread. However, experimental evidence on how genetic diversity influences total parasite load is variable.

Exploring local immunological adaptation of two stickleback ecotypes by experimental infection and transcriptome-wide digital gene expression analysis [PDF]

open access: yes, 2012
Understanding the extent of local adaptation in natural populations and the mechanisms that allow individuals to adapt to their native environment is a major avenue in molecular ecology research. Evidence for the frequent occurrence of diverging ecotypes

Parasites of Oreoleuciscus potanini (Cyprinidae) from lakes of Khar Us Nuur National Park (Mongolia)

open access: yesNature Conservation Research: Заповедная наука, 2020
Freshwater ecosystems of Mongolia belong to the three major Central Asian drainage systems: Arctic drainage, Amur River drainage, and Central Asian Internal drainage. The Great Lakes Depression takes considerable part of the latter.

Descriptions of diplostomid metacercariae (Digenea: Diplostomidae) from freshwater fishes in the Tshwane area [PDF]

open access: yes, 2013
The metacercarial (larval) stages of diplostomid digeneans are known to inhabit freshwater fish, causing tissue damage in the process. Due to their widespread diversity, little is known about their life cycle. The classification of these parasitic stages

Transcriptome profiling of immune tissues reveals habitat-specific gene expression between lake and river sticklebacks [PDF]

open access: yes, 2016
The observation of habitat-specific phenotypes suggests the action of natural selection. The three-spined stickleback (Gasterosteus aculeatus) has repeatedly colonized and adapted to diverse freshwater habitats across the northern hemisphere since the ...

Phylogenetic position of Diplostomum spp. from New World herons based on complete mitogenomes, rDNA operons, and DNA barcodes, including a new species with partially elucidated life cycle [PDF]

open access: yes, 2020
Diplostomum ardeae Dubois, 1969 has seldom been reported since its description from the great blue heron (Ardea herodias L., 1758) in the USA. Sequences obtained in this study from the barcode region of cytochrome c oxidase 1 (CO1) in diplostomids from ...

Local differences in immunocompetence reflect resistance of sticklebacks against the eye fluke Diplostomum pseudospathaceum

open access: yesParasitology, 2005
We investigated population differences in immunological adaptation of three-spined sticklebacks (Gasterosteus aculeatus) to one of their most abundant macroparasites, the eye fluke Diplostomum pseudospathaceum. We compared infection success in lab-bred fish of 2 populations in northern Germany, from a lake, where eye flukes are prevalent, and a river ...

Histofluorescent and ultrastructural demonstration of biogenic amines in daughter sporocyst ofDiplostomum pseudospathaceumNiewiadomska, 1984 (Digenea) [PDF]

open access: yesAnnales de Parasitologie Humaine et Comparée, 1990
The aminergic neurons in D. pseudospathaceum daughter sporocysts were studied by fluorescence histochemistry and electron microscopy. Green fluorescence showing the presence of catecholamines was present in the central and peripheral nervous systems.
