The avian bill is a textbook example of how evolution shapes morphology in response to
changing environments. Bills of seed‐specialist finches in particular have been the focus of …

The ecological co‐dependency between plants and hummingbirds is a classic example of a
mutualistic interaction: hummingbirds rely on floral nectar to fuel their rapid metabolisms …

Both the magnitude and the urgency of the task of assessing global biodiversity require that
we make the most of what we know through the use of estimation and extrapolation …

Patterns of connectance and strength of mutual dependence in mutualisms have been
examined by comparing the fraction of possible pairwise interactions established in a series …

It has been great fun to write this book, even though it has taken longer than planned, and
occasionally been exasperating. The most difficult problem was deciding what to exclude …

How biotic interactions, current and historical environment, and biogeographic barriers
determine community structure is a fundamental question in ecology and evolution …

Assemblages of neotropical hummingbirds are organized according to parameters of
available resources and morphological-behavioral attributes of particular hummingbird …

The overall objective is to compare the ecological impact of bird-flower coevolution in
different geographical areas. However, it is first necessary to define the parameters of such …

Understanding the relative importance of multiple processes on structuring species
interactions within communities is one of the major challenges in ecology. Here, we …

Ecological communities are organized in complex ecological networks. Trait‐based
analyses of the structure of these networks in highly diversified species assemblages are …
