CNPS Alliance: Allium spp. - Streptanthus spp. - Hesperolinon spp ...
There are approximately 80 Allium species in California, and 24 Allium taxa have some affinity to serpentine soils (Calflora 2020). Allium cratericola is a small, perennial herb with flat or widely channeled leaves and pink flowers in spring and early summer.
Adaptations to the stressful combination of serpentine soils and ...
2023年3月13日 · In our study, we analyzed 24 species with varying serpentine affinity, from strictly serpentine plants to generalist plants, from two ultramafic shrublands in southern Spain, considering four FTs: plant height (H), leaf area (LA), specific leaf …
Evolutionary Ecology of Plant Adaptation to Serpentine Soils
We review the defining properties of serpentine soil and the pioneering work leading to three established physiological and evolutionary mechanisms hypothesized to be responsible for serpentine tolerance: tolerance of a low calcium-to-magnesium ratio, avoidance of Mg toxicity, or a high Mg requirement.
Serpentine Soils and Plant Adaptations - US Forest Service
Unique flora have evolved on serpentine soils, especially adapted to survive severe hardships of drought, heavy metals, and nutrient stress. The Klamath-Siskiyou Mountains of northwest California and southwest Oregon are the largest serpentine area in North America.
American Journal of Botany - Botanical Society of America
2014年2月1日 · Here, I describe one of the first and most important papers on serpentine plant endemism, “Intraspecific variability in the response of certain native plant species to serpentine soil,” published in the American Journal of Botany by Arthur Kruckeburg in 1951. This paper has been cited 119 times in ecology and evolution journals (Web of ...
Nickel accumulation in leaves, floral organs and rewards varies …
2014年8月5日 · Results from mixed-model ANCOVA and pre-planned contrasts of Ni accumulation to leaves, pistils, anthers and nectar (‘organ/reward type’) of seven mustard species that vary in their affinity to serpentine soil (‘habitat affinity’) when grown in either Ni-supplemented or control soils (‘soil treatment’).
We review the defining properties of serpentine soil and the pioneering work leading to three established physiological and evolutionary mechanisms hypothesized to be responsible for serpentine tolerance: tolerance of a low calcium-to-magnesium ratio, avoidance of Mg toxicity, or a high Mg requirement.
ORIGINS AND CONSEQUENCES OF SERPENTINE ENDEMISM IN …
2010年8月31日 · We used a database of serpentine affinity (Safford et al. 2005) to assign every taxon in the California flora (5800+) to one of three categories of habitat specialization: “serpentine endemic”—taxa with >85% of known occurrences on serpentine soils (score of 4.5 to 6.0); “serpentine tolerator”—taxa observed both on and off ...
Serpentine soils are an important natural resource in California. They support a wide range of unique and rare plant and animal life. Taking simple, common-sense precautions helps reduce the risk to residents who have serpentinitic soils or rock on their property.
Evolutionary dynamics of serpentine adaptation in - Springer
2011年7月29日 · Here, the closer affinity of serpentine accessions with calcicolous taxa, rather than with neighbouring serpentine species from Anatolia or the Balkans, suggests independent adaptive divergence events on ultramafics.
