Background Most tropical and subtropical plants are biotically pollinated, and insects are the
major pollinators. A small but ecologically and economically important group of plants …

Parasitic plants have profound effects on the ecosystems in which they occur. They are
represented by some 4000 species and can be found in most major biomes. They acquire …

Nectar properties tend to be similar for plants visited by the same kinds of pollinators, and
much of the available information on nectar chemistry has been collected in the context of …

Our knowledge of the ecology of tropical rain-forest trees is limited, with detailed information
available for perhaps only a few hundred of the many thousand of species that occur. Yet a …

Pollinators-insects, birds, bats, and other animals that carry pollen from the male to the
female parts of flowers for plant reproduction-are an essential part of natural and agricultural …

▪ Abstract Mistletoes are a diverse group of parasitic plants with a worldwide distribution. The
hemiparasitic growth form is critical to understanding their biology, buffering variation in …

Specialization in plant–pollinator relationships is a core concept in discussions of plant
evolution and ecology; it is central to our thinking, not just about the ecology of plant …

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

Ecology Letters (2011) 14: 877–885 Abstract A major current challenge in evolutionary
biology is to understand how networks of interacting species shape the coevolutionary …

Australia, the flattest, driest, and geologically oldest vegetated continent, has a uniquely high
proportion of nutrient‐poor soils. We develop a “Nutrient‐Poverty/Intense‐Fire Theory,” …
