There is mounting evidence that parasites can influence the composition and structure of natural animal communities. In spite of this, it is difficult to assess just how important parasitism is for community structure because very few studies have been designed specifically to address the role of parasites at the community level, no doubt because it is difficult to manipulate the abundance of parasites in field experiments. Here, we bring together a large amount of published information on… 

Climate change, parasitism and the structure of intertidal ecosystems

The likely interactions between climate change and parasitism are discussed in the context of intertidal ecosystems, and the extreme sensitivity of cercarial production in parasitic trematodes to increases in temperature is documented, and how global warming could lead to enhanced trematode infections is discussed.

Ecology of parasites in mudflat ecosystems

This chapter illustrates and explores how the resulting parasite-host interactions can affect host populations, communities and food webs in mudflat ecosystems, equalling in importance the effects resulting from other species interactions, such as predation and competition.

Ecology and effects of metazoan parasites of fish in transitional waters

Abstract Abstract Given the abundance, heterogeneity and ubiquity of parasitic organisms, understanding how they influence biodiversity, evolution, health and ecosystem functionality is crucial,

The Ecological Importance of Amphipod–Parasite Associations for Aquatic Ecosystems

As seen from the literature, amphipod–parasite systems are likely a key component of ecological processes, but more quantitative data from natural populations and field evidence are necessary to support the results obtained by experimental research.

The ecology, evolution, impacts and management of host-parasite interactions of marine molluscs.

Quantifying the biomass of parasites to understand their role in aquatic communities

An approach to quantify the masses of helminth parasites and helps validate more traditional methods involving length-mass conversion, which aim to facilitate future investigations into the ecological significance of parasites, particularly with respect to ecosystem energetics.

Parasite ecology in freshwater wetlands: Consequences for hosts, communities and ecosystems

In both the laboratory and an outdoor mesocosm experiment, there is no evidence that tadpoles alter their behavior to reduce the risk of infection prior to direct contact with parasites, despite showing strong responses to predation risk.

Geographical variation in metacercarial infection levels in marine invertebrate hosts: parasite species character versus local factors

Although the magnitude of variation in infection levels within parasite species pairs was independent of scale in crustacean hosts, infection levels in bivalves increased in variability at large (>100 km) spatial scales, the results suggest that there is a considerable geographical consistency in parasite load, especially in crustACEan hosts.

Rare inventory of trematode diversity in a protected natural reserve

It is concluded that life cycle complexity, in addition to parasite diversity and trematode species richness, can provide valuable information on ecosystem health and should therefore be considered in future studies.



Manipulation of host behaviour by parasites: ecosystem engineering in the intertidal zone?

It is shown that predation of limpets by anemones is possible when they share the same cockle shell, and the ecological consequences of this behavioural alteration for two invertebrates species commonly associated with cockles, the anemone Anthopleura aureoradiata and the limpet Notoacmea helmsi are investigated.

Evolutionary biology of parasites

In demonstrating the importance of parasitic interactions for determining population patterns and geographical distributions, Dr. Price integrates the biological attributes that characterize parasites ranging from such diverse groups as viruses, bacteria, protozoa, and fungi, to helminths, mites, insects, and parasitic flowering plants.

Competition and Predation in Marine Soft-Sediment Communities

It is argued that softsediment habitats are sufficiently different from other communities that different paradigms are needed, and paradigs of co~nmunity organization based on other habitats seem to offer little insight into the structure of marine soft-sediment communities.

The influence of parasites in ecosystems, especially on biodiversity, is discussed. Various examples illustrate the role that parasites play in the outcome of interspecific competition, in the

Can Models of Soft-Sediment Community Structure Be Complete Without Parasites?

The greatest challenge for future research in this area is the development of experimental methods for manipulating the abundance of parasites under field conditions.

Ecological effects of larval trematode infestation on littoral marine invertebrate populations

Mutualism, Facilitation, and the Structure of Ecological Communities

Positive interactions occur when one organism makes the local environment more favorable for another either directly ( such as by reducing thermal stress via shading or decreasing wind stress via baffling) or indirectly (such as by removing competitors or deterring predators of that species).

Parasitic castration: host species preferences, size-selectivity and spatial heterogeneity

Investigating host-parasite population dynamics in a marine intertidal community of three barnacle host species found the parasitic castrator most heavily infected the least abundant host and H. balani showed size-selective parasitism inC. fissus, but not in C. dalli.
