body size and allometric shape variation in the molly poecilia vivipara along a gradient of salinity and predation.	phenotypic diversity among populations may result from divergent natural selection acting directly on traits or via correlated responses to changes in other traits. one of the most frequent patterns of correlated response is the proportional change in the dimensions of anatomical traits associated with changes in growth or absolute size, known as allometry. livebearing fishes subject to predation gradients have been shown to repeatedly evolve larger caudal peduncles and smaller cranial regions u ...	2014	25471469
redescription of ascocotyle (ascocotyle) felippei travassos, 1928 (digenea: heterophiydae) with new synonymies.	the heterophyid trematode ascocotyle (ascocotyle) felippei travassos, 1928, is redescribed and new data on its life cycle are provided, based on types and metacercariae found in the heart bulb and gills of naturally infected guppies, poecilia vivipara (new fish intermediate host), from a coastal lagoon in rio de janeiro, brazil. examination of the type and all voucher specimens of a. (a.) felippei collected by travassos in the type host and locality in brazil has shown that they possess only 32 ...	2007	18314695
