Aim
What factors set species' range edges? One general hypothesis, often attributed to Darwin and MacArthur, is that interspecific competition prevents species from inhabiting the warmest portions along geographic gradients (i.e., low latitudes or low elevations). A prediction arising from this Darwin–MacArthur hypothesis is that lower elevation species are better competitors than related higher...
Aim
To test whether intra‐ and interspecific patterns in body mass along elevational gradients follow Bergmann's rule for a subset of tropical montane passerines.
Location
Tropical elevational gradients in New Guinea, Borneo, Peru and Costa Rica.
Methods
I used linear regressions to assess intraspecific patterns in body mass along elevational gradients in common New Guinean passerines (2697 mist‐netted...
