Tropical montane species are characterized by narrow elevational distributions. Recent
perspectives on mechanisms maintaining these restricted distributions have emphasized …

Does competition influence patterns of coexistence between closely related taxa? Here we
address this question by analyzing patterns of range overlap between related species of …

1. We report that interspecific territoriality is a common spacing mechanism among closely
related bird species distributed along a primary successional gradient in the meander belt of …

Tropical mountains harbor exceptionally high biodiversity, which is in part due to the marked
elevational stratification of tropical biotas. However, the factors that influence the evolution of …

Globally, birds have been shown to respond to climate change by shifting their elevational
distributions. This phenomenon is especially prevalent in the tropics, where elevational …

Species' geographic ranges are limited by climate and species interactions. Climate is the
prevailing explanation for why species live only within narrow elevational ranges in …

Members of different species often engage in aggressive contests over resources. This
series of aggressive contests between species may result in an interspecific dominance …

Montane species worldwide are shifting upslope in response to recent temperature
increases. These upslope shifts are predicted to lead to mountaintop extinctions of species …

Understanding how biotic and abiotic interactions influence community assembly and
composition is a fundamental goal in community ecology. Addressing this issue is …

The contribution of interspecific competition to structuring population and community
dynamics remains controversial and poorly tested. Interspecific competition has long been …
