Arbuscular Mycorrhizal Fungi May Account for a Phosphorus‐Facilitation Strategy
ABSTRACT Mycorrhizal phosphorus (P)‐scavenging strategies are inefficient in severely P‐impoverished environments; yet many mycorrhizal species occur here. How these species acquire P and how their acquisition coordinates with root and leaf traits remain unknown.

Ecological niches and biogeography of nitrogen‐fixing plants in Europe
Despite sharing N fixation as a common trait, European legume and actinorhizal plant lineages occupy strikingly divergent ecological niches shaped by their evolutionary histories and physiological adaptations. Advanced symbiont control allows IRLC legumes to expand into northern, mesic regions, while non‐IRLC legumes are more common in Mediterranean ...

Abstract Introduction The restoration of degraded ecosystems is an important means of promoting and conserving biodiversity. However, restoration projects on average fail to reach target biodiversity levels within the time frames they are studied. Competition from non‐native groundlayer grasses and forbs, potential facilitative effects of plant–plant ...

More Science Than Art: The First Botanical Garden in Portugal (c. 1650)
ABSTRACT Gabriel Grisley, a German physician, came to Portugal and founded a garden near the Xabregas River in Lisbon, during the 1610s under the Spanish kings' rule. In view of the utility a botanic garden represented for the kingdom, he was able to obtain a royal privilege from King João IV during the Restauration War against the Spanish (1640–1668).
