Cím:Finding them before they find us: Informatics, parasites, and environments in accelerating climate change / Daniel R. Brooks, Eric P. Hoberg, Walter A. Boeger, Scott L. Gardner, Kurt E. Galbreath, Dávid Herczeg, Hugo H. Mejía-Madrid, S. Elizabeth Rácz, Altangerel Tsogtsaikhan Dursahinhan

Megjegyzések:Parasites are agents of disease in humans, livestock, crops, and wildlife and are powerful representations of theecological and historical context of the diseases they cause. Recognizing a nexus of professional opportunities and globalpublic need, we gathered at the Cedar Point Biological Station of the University of Nebraska in September 2012 to formulatea cooperative and broad platform for providing essential information about the evolution, ecology, and epidemiology ofparasites across host groups, parasite groups, geographical regions, and ecosystem types. A general protocol, documentation-assessment-monitoring-action (DAMA), suggests an integrated proposal to build a proactive capacity to understand,anticipate, and respond to the outcomes of accelerating environmental change. We seek to catalyze discussion and mobilizeaction within the parasitological community and, more widely, among zoologists and disease ecologists at a time ofexpanding environmental perturbation.

Cím:Helminth Parasites of the Pelophylax esculentus Complex (Anura: Ranidae) in Hortobágy National Park (Hungary) / Dávid Herczeg, Judit Vörös, Zsolt Végvári, Yuriy Kuzmin, Daniel R. Brooks
Dátum:2016
ISSN:1525-2647
Megjegyzések:The Document, Assess, Monitoring, Act (DAMA) protocol details an approach to integrating informationabout parasites into large-scale studies of biodiversity, climate change, and emerging diseases. This study represents an effort toput the DAMA protocol into practice. We collected 101 individuals of protected ranid frogs belonging to the Pelophylaxesculentus complex during 2012 and 2013 in the Hortoba?gy National Park (HNP) in eastern Hungary in an area where aninventory of amphibian helminths had been conducted 40 yr previously. Collecting sites included flowing water, a fish pondsystem, and a wetland marsh system. We found the following helminth species: Digeneans: Diplodiscus subclavatus,Haematoloechus variegatus, Opisthioglyphe ranae, Pleurogenes claviger, Pleurogenoides medians; Nematodes: Oswaldocruziafiliformis, Rhabdias esculentarum; and Acanthocephala: Acanthocephalus ranae. Rhabdais esculentarum is a newspecies for the Hungarian fauna and P. ridibundus represents a new host record for R. esculentarum while D. subclavatus,P. claviger, and P. medians are new species for the helminthofauna of the HNP. Our findings showed a significant discrepancyfrom the results of baseline inventories carried out 40 yr ago, although the reasons for this discrepancy are not clear. We suspectthat the previously reported helminth species that we did not encounter are restricted to Pelophylax lessonae, a host we have notyet collected at this location, but factors associated with climate change or anthropogenic impacts cannot be ruled out.

Cím:Sympatry in a nightingale contact zone has no effect on host-specific blood parasite prevalence and lineage diversity / William Jones, Radka Reifová, Jiří Reif, Petr Synek, Michal Šíma, Pavel Munclinger
Dátum:2024
ISSN:0020-7519
Megjegyzések:Parasites are a key driving force behind many ecological and evolutionary processes. Prevalence and diversity of parasites, as well as their effects on hosts, are not uniform across host species. As such, the potential parasite spillover between species can significantly influence outcomes of interspecific interactions. We screened two species of Luscinia nightingales for haemosporidian blood parasites (Plasmodium, Leucocytozoon and Haemoproteus) along an approximately 3000 km transect in Europe, incorporating areas of host distant allopatry, close allopatry and sympatry. We found significant differences in infection rates between the two host species, with common nightingales having much lower parasite prevalence than thrush nightingales (36.7% versus 83.8%). This disparity was mostly driven by Haemoproteus prevalence, which was significantly higher in thrush nightingales while common nightingales had a small, but significantly higher, Plasmodium prevalence. Furthermore, we found no effect of proximity to the contact zone on infection rate in either host species. Despite having lower infection prevalence, common nightingales were infected with a significantly higher diversity of parasite lineages than thrush nightingales, and lineage assemblages differed considerably between the two species, even in sympatry. This pattern was mostly driven by the large diversity of comparatively rare lineages, while the most abundant lineages were shared between the two host species. This suggests that, despite the close evolutionary relationships between the two nightingales, there are significant differences in parasite prevalence and diversity, regardless of the distance from the contact zone. This suggests that spillover of haemosporidian blood parasites is unlikely to contribute towards interspecific interactions in this system.

Cím:Adaptive Host-Abandonment of Ectoparasites Before Fledging? Within-Brood Distribution of Nest Mites in House Sparrow Broods / Krisztián Szabó, Anita Szalmás, András Liker, Zoltán Barta
Dátum:2008
ISSN:0022-3395
Megjegyzések:We studied the within-brood distribution of a haematophagous mite Pellonyssus reedi living on nestling house sparrows (Passer domesticus) near the time of fledging. We measured the natural level of infestation of individual nestlings, and determined the feeding efficiency of mites, by scoring their feeding status. Within-brood distribution of mite loads was unrelated to nestling body mass, tarsus length, or immunocompetence. These results did not support parasite preference for large or susceptible hosts. Mite feeding-efficiency was also unrelated to these nestling characteristics, confirming that large nestlings or nestlings with less-developed immunocompetence did not provide superior feeding conditions for mites. Therefore, our results do not support the hypothesis that within-brood distribution of avian ectoparasites is explained by the parasites' preferences for characteristics, such as large body size or low immunocompetence, that make nestlings suitable hosts. On the other hand, we found that mite loads were negatively correlated with nestling age and feather length, suggesting that nestlings closer to fledging harbored fewer mites then their less-developed nestmates. Furthermore, feather length had a stronger relationship with parasite distribution than did nestling age. We presume, therefore, that feather characteristics, i.e., length, may serve as a signal for mites to perceive the ready-to-fledge state of nestlings, inducing abandonment behavior. These results support another, largely neglected hypothesis, i.e., that the avoidance or abandonment of those nestlings that are close to fledging may also explain the parasites' distribution in a brood. This hypothesis is based on the argument that many nest-dwelling ectoparasites breed in the nest material and emerge only periodically to feed on nestlings. In such parasites, the ability to recognize and avoid mature fledglings can be adaptive because this may help the parasites to avoid their removal from the nest so they can continue to reproduce by feeding on unfledged chicks of the current or later broods. Our results suggest that adaptive host-abandonment by nest-dwelling ectoparasites can influence within-brood parasite distributions around the time of fledging.
