Breeding origins of a uniquely regular migrant songbird in the Galápagos Islands.

Little is known about the causes and consequences of alternative pathways flown by long-distance migratory birds. Bobolinks () breed in grasslands across northern North America and migrate from their breeding grounds toward the eastern Atlantic Coast and then proceed through the Caribbean to South America. However, a small but regular number of Bobolinks have been recorded on the Galapagos Islands.

Host-specific soil microbes contribute to habitat restriction of closely related oaks ( spp.).

Habitat divergence among close relatives is a common phenomenon. Studying the mechanisms behind habitat divergence is fundamental to understanding niche partitioning, species diversification, and other evolutionary processes. Recent studies found that soil microbes regulate the abundance and diversity of plant species.
