Plants allocate nutrients to specific leaf cell types; eudicots are thought to predominantly
allocate phosphorus (P) to epidermal/bundle sheath cells. However, three Proteaceae …

Plants allocate nutrients to specific leaf cell types, with commelinoid monocots preferentially
allocating phosphorus (P) to the mesophyll and calcium (Ca) to the epidermis, whereas the …

Proteaceae species in south‐western Australia occur on severely phosphorus (P)‐
impoverished soils. They have very low leaf P concentrations, but relatively fast rates of …

Background and aims Plant species richness increases with declining soil phosphorus (P)
availability, especially for Proteaceae in old infertile landscapes. This difference in richness …

Proteaceae in southwestern Australia have evolved on some of the most phosphorus-
impoverished soils in the world. They exhibit a range of traits that allow them to both acquire …

Over 650 Proteaceae occur in south-western Australia, contributing to the region's
exceptionally high biodiversity. Most Proteaceae occur exclusively on severely nutrient …

How species coexist despite competing for the same resources that are in limited supply is
central to our understanding of the controls on biodiversity,. Resource partitioning may …

Proteaceae are almost all non‐mycorrhizal and most species produce proteoid (= cluster)
roots when grown in low‐phosphorus (P) soils. In south‐western Australia and the Cape …

Species diversity is commonly hypothesized to result from trade-offs for different limiting
resources, providing separate niches for coexisting species 1–4. As soil nutrients occur in …

Australia harbors some of the most nutrient-impoverished soils on Earth. Southwestern
Australian soils are especially phosphorus (P) impoverished, due to the age of this ancient …
