ABSTRACT.- Landscape heterogeneity may affect components of biodiversity, including pollinators and the ecosystem function they perform. Landscape heterogeneity may also affect pollinator movement and pollen and gene flow. We assessed how changes in landscape compositional heterogeneity generated by agricultural activities affect the pollen transport service provided by insect pollinators.

Soybeans (Glycine max L.), originating in China, were introduced to South America in the late 19th century after passing through North America. South America is now a major soybean-producing region, accounting for approximately 40% of the global soybean production. Crops like soybeans gradually adapt to the local climate and human-selected conditions, resulting in beneficial variations during cultivation in different regions. Comparing the phenotypic and genetic variations in soybeans across different regions is crucial to determining the variations that may enhance soybean productivity.
