Ecosystem energetic implications of parasite and free-living biomass in three estuaries
Parasites can have strong impacts but are thought to contribute little biomass to ecosystems. We quantified the biomass of free-living and parasitic species in three estuaries on the Pacific coast ofExpand

DESCRIPTION AND PROPOSED LIFE CYCLE OF MARITREMA NOVAEZEALANDENSIS N. SP. (MICROPHALLIDAE) PARASITIC IN RED-BILLED GULLS, LARUS NOVAEHOLLANDIAE SCOPULINUS, FROM OTAGO HARBOR, SOUTH ISLAND, NEW ZEALAND
Maritrema novaezealandensis n. sp. is described from Otago Harbor, South Island, New Zealand, on the basis of adult specimens collected from the Red-billed gull, Larus novaehollandiae scopulinus, andExpand

Four trematode cercariae from the New Zealand intertidal snail Zeacumantus subcarinatus (Batillariidae)
Abstract The cercariae and sporocysts (or rediae) of four trematode species are described from the intertidal snail Zeacumantus subcarinatus: a distome xiphidiocercaria assigned to the genus RenicolaExpand

Larval helminths in intermediate hosts: does competition early in life determine the fitness of adult parasites?
Density-dependent effects on parasite fitness have been documented from adult helminths in their definitive hosts. There have, however, been no studies on the cost of sharing an intermediate hostExpand

Production of marine trematode cercariae: a potentially overlooked path of energy flow in benthic systems
Parasites, in particular trematodes, are unseen but ubiquitous components of marine intertidal ecosystems. Although parasites are known to affect population dynamics and food web structure, theirExpand

Impact of trematodes on host survival and population density in the intertidal gastropod Zeacumantus subcarinatus
Ecological studies have demonstrated that parasites are capable of influencing various aspects of host life history and can play an important role in the structure of animal populations. WeExpand

Relating bird host distribution and spatial heterogeneity in trematode infections in an intertidal snail—from small to large scale
Shorebird abundance and spatial distribution of larval trematodes in the New Zealand mudsnail, Zeacumantus subcarinatus, were investigated in soft-sediment intertidal bays within Otago Harbour, SouthExpand

In vitro cultivation of Maritrema novaezealandensis (Microphallidae): the effect of culture medium on excystation, survival and egg production
In this study, the effect of the composition of culture medium on excystation, growth, survival and egg production was investigated for the recently discovered microphallid trematode MaritremaExpand

Increased Surfacing Behavior In Longnose Killifish Infected by Brain-Encysting Trematode
Abstract: Some parasites modify the behavior of intermediate hosts to increase the probability of transmission to the next host in their life cycle. In habitats where this is common, parasites playExpand

Parasitism shaping host life-history evolution: adaptive responses in a marine gastropod to infection by trematodes.
1. Variation in life-history strategies among conspecific populations indicates the action of local selective pressures; recently, parasitism has been suggested as one of these local forces. 2.Expand
