For instance, the fitness of most organisms decreases in either direction away from the optimal climate (although more complex nonlinear functions can also occur). Hence, changes in climate should often generate nonlinear effects on fitness, which contr ...

If, as the evidence suggests, the inherited variability of susceptibility to cholera is correlated to ABO blood groups, then this third condition is easily satisfied. ...

Schistosoma mansoni
Schistosoma mansoni is a significant parasite of humans, a trematode that is one of the major agents of the disease schistosomiasis which is one type of helminthiasis, a neglected tropical disease. The schistosomiasis caused by Schistosoma mansoni is intestinal schistosomiasis.Schistosomes are atypical trematodes in that the adult stages have two sexes (dioecious) and are located in blood vessels of the definitive host. Most other trematodes are hermaphroditic and are found in the intestinal tract or in organs, such as the liver. The lifecycle of schistosomes includes two hosts: a definitive host (i.e. human) where the parasite undergoes sexual reproduction, and a single intermediate snail host where there are a number of asexual reproductive stages.S. mansoni is named after Sir Patrick Manson, who first identified it in Formosa (now Taiwan).
