RESEARCH

Profound climatic changes have transformed the globe in the past two million years. During the cold episodes, ice caps covered vast areas of the temperate zone. In the tropics, rain forests were reduced to small and isolated patches (refugia). Some bird species became extinct because they were unable to adapt to such drastic ecological modifications. Others survived, responding to geographic isolation by eventually becoming new species-a process known as speciation. In the Monte Biome of Argentina, where Dr. Vuilleumier is currently conducting research, no such isolation is detectable. Yet, bird speciation occurred there, as shown by species distribution patterns. Solving this apparent paradox is one of the goals of Dr. Vuilleumier's research.

The Monte, a 600,000-square-kilometer crescent of shrublike vegetation found only in Argentina, is home to hundreds of bird species, several of which occur only there. Several bird species of the Monte have closely related species (called sister species) in neighboring regions of different vegetation types. Yet geographical isolation between these species is lacking, and their distributions abut, a phenomenon termed parapatry by evolutionary biologists. By analyzing these birds' distributions and phylogenetic relationships, Dr. Vuilleumier hopes to find clues to their origins. He also hopes to find clues about how to preserve these birds.

The task of making a complete inventory for the diverse avian assemblage of the Monte is urgent, as this biome is seriously threatened by livestock breeding that has resulted in overgrazing. His project, affectionately titled "The Full Monte," is divided into two parts. The first calls for a complete census of the region's landbirds by a joint team of scientists from the Museum and various South American institutions. The second phase will enter the information gathered from specimen collection and field observations into a combined database. This database will be used for research into evolutionary problems and to guide conservation action in order to protect the Monte's unique ecosystem and its resulting biodiversity.
