Functional traits can determine pairwise species interactions, such as
those between plants and pollinators. However, the effects of biogeography
and evolutionary history on trait-matching and trait-mediated resource
specialization remain poorly understood. We compiled a database of 93
mutualistic hummingbird-plant networks (including 181 hummingbird and
1,256 plant species), complemented by morphological measures of
hummingbird bill and floral corolla length. We divided the hummingbirds
into their principal clades and used knowledge on hummingbird biogeography
to divide the networks into four biogeographical regions: Lowland South
America, Andes, North & Central America, and the Caribbean
islands. We then tested: (i) whether hummingbird clades and
biogeographical regions differ in hummingbird bill length, corolla length
of visited flowers and resource specialization, and (ii) whether
hummingbirds’ bill length correlates with the corolla length of their food
plants and with their level of resource specialization. Hummingbird clades
dominated by long-billed species generally visited longer flowers and were
the most exclusive in their resource use. Bill and corolla length and the
degree of resource specialization were similar across mainland regions,
but the Caribbean islands had shorter flowers and hummingbirds with more
generalized interaction niches. Bill and corolla length correlated in all
regions and most clades, i.e. trait-matching was a recurrent phenomenon in
hummingbird-plant associations. In contrast, bill length did not generally
mediate resource specialization, as bill length was only weakly correlated
with resource specialization within one hummingbird clade (Brilliants) and
in the regions of Lowland South America and the Andes in which plants and
hummingbirds have a long co-evolutionary history. Supplementary analyses
including bill curvature confirmed that bill morphology (length and
curvature) does not in general predict resource specialization. These
results demonstrate how biogeographical and evolutionary histories can
modulate the effects of functional traits on species interactions, and
that traits better predict functional groups of interaction partners (i.e.
trait-matching) than resource specialization. These findings reveal that
functional traits have great potential, but also key limitations, as a
tool for developing more mechanistic approaches in community ecology.
We compiled a dataset of 93 quantitative hummingbird-plant interaction
networks from localities distributed widely across the Americas. Each of
the 93 networks describes interaction frequencies within assemblages of
hummingbirds and their food plants in a specific location. We only
included mutualistic interactions in which a given hummingbird was
observed drinking nectar and touching the stigma / anthers of the given
flower, thereby potentially acting as a pollinator. The networks were
sampled to represent all hummingbird clades and hummingbird-visited plant
families without any taxonomic bias. Species names of the hummingbirds
follow the International Ornithological Committee World List (IOC version
9.2; www.worldbirdnames.org). Hummingbirds were divided into nine clades
following McGuire et al. (2014). Species names and families of the plants
follow ‘The Plant List’ (TPL version 1.1; www.theplantlist.org), with a
few exceptions where species names of recorded plants were not found in
TPL.
