The smew (Mergellus albellus) is a species of duck and is the only living member of the genus Mergellus. The genus is closely related to Mergus and is sometimes included in it; genetic studies have shown that it is the sister taxon to Mergus and Lophodytes. The smew has hybridised with the common goldeneye (Bucephala clangula).

Connections between topic areas Semantic bridges
Semantic bridges connect parts of the graph that would otherwise be more separate. A bridge is a structural signal in this analysis, not a claim that the two topic areas are equivalent.
For Smew, one of the stronger structural bridges in this analysis connects Smew with Taxonomy. Bridges highlight paths between different parts of the map and can reveal research angles that are easy to miss in a flat list.
