By facilitating plant reproduction, pollinators perform a crucial ecological function that
supports the majority of the world's plant diversity, and associated organisms, and a …

The idea of pollination syndromes has been largely discussed but no formal quantitative
evaluation has yet been conducted across angiosperms. We present the first systematic …

Orchidaceae show remarkable diversity in pollination strategies, but how these strategies
vary globally is not entirely clear. To identify regions and taxa that are data-rich and lend …

A unique and personal insight into the ecology and evolution of pollinators, their
relationships with flowers, and their conservation in a rapidly changing world. The …

Sampling ecological interactions presents similar challenges, problems, potential biases
and constraints as sampling individuals and species in biodiversity inventories. Robust …

The decline of biodiversity with latitude has received great attention, but both the concise
pattern and the causes of the gradient are under strong debate. Most studies of the …

Biotic interactions are believed to play a role in the origin and maintenance of species
diversity, and multiple hypotheses link the latitudinal diversity gradient to a presumed …

Background Network analyses of plant-animal interactions hold valuable biological
information. They are often used to quantify the degree of specialization between partners …

Background Ecologists and evolutionary biologists are becoming increasingly interested in
networks as a framework to study plant–animal mutualisms within their ecological context …

Species-rich tropical communities are expected to be more specialized than their temperate
counterparts [1–3]. Several studies have reported increasing biotic specialization toward the …
