Determination of the infection of Lymnaea-gedrosina to trematodes Larval in the water region of Khuzestan
Background & Objective: The province of Khuzestan with its wide geographical area and its tropical climate is susceptible for the maintenance of snails. One of the prevalent intermediate hosts for trematode in this area is the gasteropode snail, Lymnaea gedrosina. This study is the first research, undertaken to determine the infection rate, biological characteristics and Longevity Lymnaea gedro...
متن کاملCommunity Structure : Larval Trematodes in Snail Hosts
In species assemblages of larval trematodes in individual snail hosts, fewer multispecies infections are observed than might be expected by chance. Both interspecific competition and the isolating effect of heterogeneity inrecruitment may explain this pattern of community structure. Here, we analyzed the expected and observed frequency of double infections, using data culled from 62 studies. Ou...
متن کاملRoubal: Seasonal occurrence of transversotrematid trematodes
Ectoparasitic Prototransversotrema steeri Angel infected Acanthopagrus australis (Günther) in western (W. Bay) and southern (S. Bay) Moreton Bay with greatest abundance in winter (June August), and none in summer (December February). This confirms previous observations on seasonality of P. steeri from a small estuary in New South Wales. Transversotrema licinum Manter, which is a new host and ge...

Dubois (1929), Rees (1932), Wesenburg-Lund (1934), Rothschild (1941), Wikgren (1956), Deforest (1957), Khan (1960a, b), Radke et all (1961), Larson (1961), Ewers (1964) and Basch (1966) have studied the larval trematodes infecting the different molluscan hosts. The seasonal variations of infection of larval trematodes in India have been studied by Soparkar (1921) Sewell (1922), Chatterji . (193...
متن کاملForaging by the mud snail, Ilyanassa obsoleta (Say), modulates spatial variation in benthic community structure
We investigated the foraging behavior of the mud snail, Ilyanassa obsoleta, and its consequences for macrobenthic community structure on mud flats on Long Island, NY, USA. Field sampling demonstrated strong spatial heterogeneity in the population densities of I. obsoleta. We experimentally tested three hypotheses: (i) I. obsoleta are strongly attracted to areas with high levels of detritus; (ii...
