There is power in numbers. Bringing researchers together to concentrate on one question is one of the most powerful ways to do science. Although individual research programs can focus on specific species, ecosystems or genes, there is an urgent need to discover the broad generalities that underlie these specific results. Synergisms happen when researchers with complementary expertise focus on the same problem, resulting in new approaches and conceptual insights. Powerful analyses result when researchers pool published data, allowing conclusions that transcend any one study. We support “working groups”: meetings where researchers work intensively on some of the most important questions in ecology and evolution.
