“…This study has examined one parasite in isolation to the many others that occur in eiders (Lapage, 1961;McDonald, 1969;Bishop & Threlfall, 1974). Interactions between different parasite species in the same host are known (Cross, 1934;Holmes, 1961Holmes, , 1962, but the possible effects of inter-species interactions on the dynamics of P. botulus have not been taken into account in this study.…”

The abundance of Profilicollis botulus was monitored in eider ducks for 3 years. No significant difference in P. botulus abundance was found between eiders taken alive and those collected dead from the shore line, or between adult males and adult females. Adult male eiders had a seasonal pattern of infection. Incubating female eiders lost their infection in almost all cases, suggesting that a seasonal pattern of infection must also occur in these birds. Eiders in their first winter had P. botulus abundances which were approximately 10 times that of adult eiders, but by the following summer the abundance had declined to that found in adults. Data are compared with previous studies undertaken on the Ythan estuary. Captive eiders were used to determine the developmental rate of female P. botulus and the percentage of administered cystacanths which established in the intestine. There was no evidence to suggest that male and female P. botulus have different life-spans.

Mating systems, parasites and plumage dimorphism in waterfowl

Despite a tendency for males of polygynous bird species to show bright or elaborate plumage, comparative analyses have failed to show any consistent relationship between male brightness or plumage dimorphism and the form of breeding systems. Here we argue that this may be partly because the opportunity for sexual selection varies between species showing serial or seasonal monogamy and life-long monogamy. In waterfowl, both the brightness of male plumage and sexual dimorphism in colouration vary between these categories of monogamy. Other ecological factors related to male brightness or plumage dimorphism include male assistance in protecting young, latitude and an index of parasite sharing. The adaptive significance of these trends is discussed.

“…Within freshwater ecosystems, attention has begun to focus on important emerging diseases (Okamura & Feist, 2011) complementing the already extensive literature that exists on a wide range of wellestablished animals parasitic on vertebrates and invertebrates, e.g. Lapage (1961), Chubb (1979), Grizzle & Brunner (2009). Parasites are now recognized as major components of ecosystems, both in terms of total biomass and especially in food web dynamics (Lafferty et al, 2006Szuroczki & Richardson, 2009).…”

Cercariae (Platyhelminthes: Trematoda) as neglected components of zooplankton communities in freshwater habitats

Zooplanktonic animals live in the open water of freshwater habitats, whilst trematodes are ubiquitous parasitic worms of aquatic vertebrates and invertebrates. A defining characteristic of trematode life cycles is the cercariae, a mainly planktonic freeliving larval stage that emerges into the aquatic environment from infected molluscan hosts. Cercariae are lecithotrophic (non-feeding) larvae analogous of meroplankton. Although millions of planktonic cercariae enter freshwater habitats on a daily basis and are capable of forming into dense clouds, they are a largely neglected component of the zooplankton community, rarely mentioned in faunal studies. Nevertheless, there is increasing evidence to suggest that cercariae have important secondary roles in aquatic food webs and energy transfer. This article reacquaints freshwater biologists with cercariae, highlighting the key characteristics of their biology and population dynamics, their role in food webs, public health and veterinary importance, and the risk of increased population densities under the influence of climate change. The reasons for their neglect in freshwater biology is evaluated and considered to be associated with zooplankton sampling methodologies being unsuitable for collecting cercariae and the paucity of identification keys in the limnological literature.
