Ecophysiological Performance of Proteaceae Species From Southern South America Growing on Substrates Derived From Young Volcanic Materials

open access: yesFrontiers in Plant Science, 2021
Southern South American Proteaceae thrive on young volcanic substrates, which are extremely low in plant-available phosphorus (P). Most Proteaceae exhibit a nutrient-acquisition strategy based on the release of carboxylates from specialized roots, named ...

Late Neolithic and Chalcolithic maritime resilience? The 4.2 ka BP event and its implications for environments and societies in Northwest Europe

open access: yesEnvironmental Research Letters, 2020
This paper deals with prehistoric communities at the end of the 3rd millennium BC in Northwest Europe in relation to the 4.2 ka BP climatic event. In particular, the question of the resilience of these communities to climatic change will be studied here ...

Nodulated White Lupin Plants Growing in Contaminated Soils Accumulate Unusually High Mercury Concentrations in Their Nodules, Roots and Especially Cluster Roots

open access: yesHorticulturae, 2021
Two white lupin (Lupinus albus L.) cultivars were tested for their capacity to accumulate mercury when grown in Hg-contaminated soils. Plants inoculated with a Bradyrhizobium canariense Hg-tolerant strain or non-inoculated were grown in two highly Hg ...

Cluster-root bearing Proteaceae species show a competitive advantage over non-cluster root species [PDF]

open access: yesAnnals of Botany, 2019
Abstract Background and aims Cluster roots (CRs) constitute a special root adaptation that enables plants to take up nutrients, especially phosphorus (P), from soils with low nutrient availability, including recent volcanic deposits.

High pH Stress Affects Root Morphology and Nutritional Status of Hydroponically Grown Rhododendron (Rhododendron spp.)

open access: yesPlants, 2020
Rhododendrons (Rhododendron spp.) are ornamental plants in the family Ericaceae that thrive in acidic soils and are challenged by neutral or alkaline soils. This soil requirement limits the locations where rhododendrons can be grown and causes chlorosis,

Root Handling Affects Carboxylates Exudation and Phosphate Uptake of White Lupin Roots

open access: yesFrontiers in Plant Science, 2020
The reliable quantification of root exudation and nutrient uptake is a very challenging task, especially when considering single root segments. Most methods used necessitate root handling e.g. root dissecting/cutting. However, there is a knowledge gap on

Assessing overall network structure in regional innovation policies: a case study of cluster policy in the West Midlands in the UK [PDF]

open access: yes, 2013
Revisiting the theoretical roots of the key concepts of “embeddedness” and “networks” that underpin many recent regional innovation polices, this paper strives to achieve a more systematic understanding of the overall network structure of geographic ...

Languages in China link climate, voice quality, and tone in a causal chain

open access: yesHumanities & Social Sciences Communications, 2023
Are the sound systems of languages ecologically adaptive like other aspects of human behavior? In previous substantive explorations of the climate–language nexus, the hypothesis that desiccation affects the tone systems of languages was not well ...

Nutrient Use Efficiency of Southern South America Proteaceae Species. Are there General Patterns in the Proteaceae Family?

open access: yesFrontiers in Plant Science, 2018
Plants from the Proteaceae family can thrive in old, impoverished soil with extremely low phosphorus (P) content, such as those typically found in South Western Australia (SWA) and South Africa.
