Abstract

Wild animals are usually infected with parasites that can alter their hosts’ trophic niches in food webs as can be seen from stable isotope analyses of infected versus uninfected individuals. The mechanisms influencing these effects of parasites on host isotopic values are not fully understood. Here, we develop a conceptual model to describe how the alteration of the resource intake or the internal resource use of hosts by parasites can lead to differences of trophic and isotopic niches of infected versus uninfected individuals and ultimately alter resource flows through food webs. We therefore highlight that stable isotope studies inferring trophic positions of wild organisms in food webs would benefit from routine identification of their infection status.

Abstract

Our capacity to predict trajectories of ecosystem degradation and recovery is limited, especially when impairments are caused by multiple stressors. Recovery may be fast or slow and either complete or partial, sometimes result in novel ecosystem states or even fail completely. Here, we introduce the Asymmetric Response Concept (ARC) that provides a basis for exploring and predicting the pace and magnitude of ecological responses to, and release from, multiple stressors. The ARC holds that three key mechanisms govern population, community and ecosystem trajectories. Stress tolerance is the main mechanism determining responses to increasing stressor intensity, whereas dispersal and biotic interactions predominantly govern responses to the release from stressors. The shifting importance of these mechanisms creates asymmetries between the ecological trajectories that follow increasing and decreasing stressor intensities. This recognition helps to understand multiple stressor impacts and to predict which measures will restore communities that are resistant to restoration.

Abstract

In recent years there has been an increasing number of papers showing how parasitism and pollution can interact with each other in aquatic organisms. Among the variety of investigated aspects especially the combined effects of pollution and simultaneous infection on the health of aquatic hosts (molluscs, crustaceans, fish, mammals) is of considerable interest. Effects of pollution on the occurrence and distribution of parasites is another interesting field of “Environmental Parasitology” attracting increasing attention. This mini-review presents some promising examples of interdisciplinary studies paying attention to the fact that under natural conditions no organism will only be affected by either parasites or pollution.

Abstract

Although the infestation with a high number of blood-feeding monogeneans anchored in the gill tissue can result in severe anaemia of the fish host (Buchmann and Bresciani, 2006; Gérard I et al i ., 2016) our study did not exhibit any obvious effect of I M. alosae i on the health status (i.e. condition factor) of the fish. Keywords: Bioindicator; Danube River; metals; monogeneans; nematodes EN Bioindicator Danube River metals monogeneans nematodes 496 502 7 03/29/22 20220401 NES 220401 Introduction Different biological indicators can be applied for the assessment of metal pollution in aquatic habitats. Interestingly, relatively high bioconcentration factors were obtained for Cd and Pb, with concentrations of Pb being approximately 251 and 33 times higher in the monogeneans and nematodes, respectively, compared to the host muscle. Significant correlations were detected between the presence of nematodes and fish weight ( I r SB s sb i = 0.73), length ( I r SB s sb i = 0.789) and height ( I r SB s sb i = 0.64) considering data from both years, while the correlation between the nematodes and the condition factor of the fish was negative ( I r SB s sb i = -0.649).
