Pollinator-mediated selection is one of the most
important factors driving adaptation in flowering plants.
However, as ecological conditions change through habitat
loss and fragmentation, the interactions among species ...
Biochemical, immunological, and biological characterization of trypanosoma cruzi populations of the andean North of Chile
(1995)
Twenty-one Trypanosoma cruzi stocks isolated from Triatoma infestans and humans of the Chilean Andean highlands were studied at the genotypic level by schizodeme and molecular karyotype analyses, which allowed a clear ...
