Introduced hosts populations may benefit of an "enemy release" through impoverishment of parasite communities made of both few imported species and few acquired local ones. Moreover, closely related competing native hosts can be affected by acquiring introduced taxa (spillover) and by increased transmission risk of native parasites (spillback). We determined the macroparasite fauna of invasive ...

Ruminants are vital elements of the Holarctic ecosystem. Little is known, however, of the structure or biology of their parasite fauna, particularly in North America. Global warming, coupled with increasing human activity in the Arctic, requires enhanced international interdisciplinary efforts to better understand the many factors, including parasites, that influence the population health of ca...

The helminth fauna of the small field mouse (Apodemus microps Kratochvil and Rosicky, 1952) and the common vole (Microtus arvalis Pallas, 1778) was studied in a pine forest at Babat (County Pest). A total of 9 parasitic helminths were recovered from the small field mouse, which is reported for the first time as a new host of Anoplocephaloides dentata, Hymenolepis fraterna, Hymenolepis diminuta ...

OBJECTIVE There is no study on the trematode parasites of Lophius piscatorius. The aim of this study is to address the lack of knowledge about the parasites of angler fish from the coasts of Turkish seas. METHODS Frozen individuals of L. piscatorius from the coasts of Izmir were brought to Ataturk University, and their visceral organs were parasitologically investigated. Parasites were fixed ...

A total of 219 deep-sea fishes belonging to five families were examined for the parasite fauna and stomach contents. The demersal fish Macrourus berglax, bathypelagic Bathylagus euryops, and mesopelagic Argentina silus, Borostomias antarcticus, Chauliodus sloani, and Lampanyctus macdonaldi were caught at 243–708m trawling depth in the Greenland and the Irminger Sea in 2002. A total of 21 differ...

1. In many host–parasite systems, infection risk can be reduced by high local biodiversity, though the mitigating effects of diversity are context dependent and not universal. 2. In aquatic ecosystems, local fauna can reduce the transmission success of parasite free-swimming infective stages by preying on them, acting as decoy hosts, or physically interfering with transmission. However, most pr...

1. It is well recognised that non-indigenous species (NIS) can affect native communities via the ‘spillover’ of introduced parasites. However, two other potentially important processes, the ‘spillback’ of native parasites from a competent NIS host, where the latter acts as a reservoir leading to amplified infection in native hosts, and the ‘dilution’ of parasitism by a NIS host acting as a sink...

Foraging herbivores face twin threats of predation and parasite infection, but the risk of predation has received much more attention. We evaluated, experimentally, the role of olfactory cues in predator and parasite risk assessment on the foraging behaviour of a population of marked, free-ranging, red-necked wallabies (Macropus rufogriseus). The wallabies adjusted their behaviour according to ...

Due to the biological uniqueness of Galápagos Islands, ectoparasites their avian fauna are relatively well-studied compared with other oceanic islands. However, in this study, quill mites (Acariformes: Prostigmata: Syringophilidae) were investigated for first time archipelago. We 7 species (out 9) and 133 specimens Darwin’s Finches genus Geospiza. Quill mite parasites confirmed two host species...

in this study, a total of 146 specimen of fish species from garmrood river of amol, mazandaran province in the summer 2011 were caught by local fishermen which including ,10 sand goby (neogobius fluviatilis),4 round goby (neogobius melanostomus), 48 capoeta capoeta, 73 albernoides bipunctatus, 5 leuciscus cephalus, 7 cobitis taenia and 4 nemacheilus nemacheilus. the fishes were transported a li...
