Schistosomes undergo dramatic changes in gross morphology and cellular composition and specialization during their transition from free-swimming cercariae in freshwater to mature adult worms, which reside in the ostensibly inimical environment of the mammalian host blood stream [ 2].
In the empirical analysis below, we account for the composition of specializations by (i) analyzing the whole group of SPs and (ii) by focusing on specializations with relatively strong representations in our sample of non-contract physicians, i.e., internists, surgeons, neurologists and gynecologists.
We performed hierarchical clustering using composition ratios and specialization coefficients from the comparison with geological and geomorphological maps and used percentages of landslide masses to assist grouping.
We thought that hierarchical clustering, using composition ratios and specialization coefficients of the comparison with thematic maps or data, was adequate to understand the similarity of the clusters.
This figure shows a dendrogram calculated by the Ward method, using composition ratios and specialization coefficients of the comparison with JEGM and SDGM, and percentages of landslide masses (Table 1).
Growth implications of the commodity price evolution have varied substantially as a result of commodity-specific price patterns and country-specific exposures and composition of commodity specialization.
This follows from different compositions of commodity specialization regarding metals, food and oil and their diverging price patterns over time.
Land use intensification caused changes in the community composition and degree of specialization.
These results suggest that strong selection pressures associated with dietary specialization affect venom composition of Conus and similar phenomena may affect the evolution of venoms of other taxa.
Conus species also exhibit interspecific differences in both venom composition [10], [11] and feeding specialization [12], [13] that together suggest that species' venoms have evolved to most effectively paralyze their particular prey.
