Larval strigeoid trematodes in anurans from southern Nigeria

Community 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...

Mismatched anti-predator behavioral responses in predator-naïve larval anurans

Organisms are adept at altering behaviors to balance the tradeoff between foraging and predation risk in spatially and temporally shifting predator environments. In order to optimize this tradeoff, prey need to be able to display an appropriate response based on degree of predation risk. To be most beneficial in the earliest life stages in which many prey are vulnerable to predation, innate ant...

Venue and Outcome in Ecological Experiments: Manipulations of Larval Anurans

Larval stages of digenetic trematodes in Melanopsis praemorsa snails from freshwater bodies in Palestine.

OBJECTIVE To detect the species of larval trematodes (cercariae) in Melanopsis praemorsa snails from 5 different fresh water bodies in Palestine. METHODS A total of 1 880 Melanopsis praemorsa snails were collected from different fresh water bodies in Palestine from October, 2008 to November, 2010. Cercariae in Melanopsis praemorsa snails were obtained by lighting and crushing methods. The beh...

Incidence of Larval Trematodes Infection and Their Seasonal Variations in the Fresh Water Molluscs of Southern · Rajasthan

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...
