The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Divergent Phosphorus‐Mining Strategies in Simple and Compound Cluster Roots in Extremely Phosphorus‐Impoverished Soils in Southwest Australia

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Most Proteaceae and some Fabaceae species produce specialised cluster roots (CRs), and are abundant in severely phosphorus (P)‐impoverished soils in southwest Australia. Two types of CRs, compound and simple, have been identified. However, the difference in their P‐mining strategies remains unclear. Therefore, we conducted glasshouse and field
