Background Floral nectar is an important determinant of plant–pollinator interactions and an
integral component of pollination syndromes, suggesting it is under pollinator-mediated …

Ecosystem services are natural processes that benefit humans. Birds contribute the four
types of services recognized by the UN Millennium Ecosystem Assessment—provisioning …

Biodiversity is organised into complex ecological networks of interacting species in local
ecosystems, but our knowledge about the effects of habitat fragmentation on such systems …

Evolutionary shifts to bird pollination (ornithophily) have occurred independently in many
lineages of flowering plants. This shift affects many floral features, particularly those …

Islands harbour much of the world's threatened biodiversity. Recent work has highlighted
how it is not species diversity per se but rather the interactions between organisms that …

Plants produce nectar to attract pollinators in the case of floral nectar (FN) and defenders in
the case of extrafloral nectar (EFN). Whereas nectars must function in the context of plant …

The intensification of agricultural practices contributes to the decline of many taxa such as
insects and wild plants. Weeds are serious competitors for crop production and are thus …

Background and Aims Floral nectar concentration and chemical composition of 26 plant
species native to the temperate forest of southern South America are reported and the …

A long-standing paradigm in biology has been that hummingbirds and passerine birds
select for different nectar properties in the plants they pollinate. Here we show that this …

Flowers are complex structures, synchronously displaying both olfactory and visual
signals/cues in the context of a particular floral morphology, that also vary in resource …
