First Report on Soil Algae From Ultramafic Substrates in Bulgaria

Blagoy A. Uzunov et al
▶️ x.gd/4VAHB

cyanobacteria/ eustigmatophycean algae/ serpentine soils

Graphical abstract: The manuscript presents the first analysis of soil algae in serpentine soils. This study identifies 19 taxa, including two globally rare species, contributing valuable insights into the biodiversity of ultramafic environments.

Compared Effects on Metrosideros laurifolia of Arbuscular Mycorrhizal Fungal Communities From Restored Laterite and Reference Ultramafic Soil

arbuscular mycorrhiza/ ecological restoration

Graphical abstract: In a greenhouse experiment using the endemic shrub Metrosideros laurifolia, we compared the functional effects of AMF community extracted from a disturbed soil restored 20 years ago with that extracted from a reference soil corresponding to a bordering dense shrubby maquis.

Direct and Element-Mediated Edaphic Effects Shape Resource-Conservative Leaf Trait Variation Across Serpentine and Limestone Soils

Shogo Ueyama, Emi Kusatake, Makiko Mimura
doi.org/10.1111/1440...

Graphical abstract: Populations of closely related Epimedium taxa inhabiting serpentine and limestone soils converged toward resource-conservative leaf trait syndromes despite strong differences in soil chemistry. Structural equation modeling revealed that edaphic variation was associated with leaf trait variation both directly and indirectly through shifts in leaf elemental composition. This study highlights multiple pathways linking edaphic heterogeneity to convergent resource-conservative leaf trait syndromes across serpentine and limestone soils.

Nickel Accumulation in the Endemic Species Odontarrhena orbelica From Pirin Mountain, Bulgaria

Dolja Pavlova et al
Link in reply 👇

Keywords: alyssum/ excluder/ hyperaccumulator/ serpentine/ ultramafic

Graphical abstract: Odontarrhena orbelica, a rare endemic species from marble area in the Pirin Mountain (Bulgaria). It is one of the small number Odontarrhena species without known ultramafic populations. O. orbelica showed Ni concentrations < 465 mg kg−1 in roots, < 142 mg kg−1 in stems, and up to 193 mg kg−1 in leaves when cultivated on ultramafic soil. This is an Ni excluder, incapable of accumulating Ni in aboveground tissues, in contrast to O. decipiens and O. muralis grown under the same soil and experimental conditions.

Nickel Hyperaccumulation by the Species of the Genus Odontarrhena From North Macedonia

Slavcho Hristovski et al
Link in reply👇

Keywords: alyssum/ bioaccumulation/ metallophytes/ plant organs/ translocation

Graphical abstract: This study assessed Ni hyperaccumulation potential, organ-specific partitioning, and soil–plant relationships in seven Odontarrhena species of the O. muralis group across ultramafic sites in North Macedonia. All investigated species occurring on ultramafic soils showed clear Ni hyperaccumulation, with leaf concentrations exceeding 25,000 mg/kg in O. skopjensis and O. chalcidica. Nickel accumulation followed a consistent organ-specific pattern (root < stem < leaf), indicating preferential allocation to aboveground tissues. These findings highlight the importance of intrinsic physiological regulation and tissue-specific sequestration in shaping Ni hyperaccumulation, reinforcing the role of Odontarrhena species as key functional components of ultramafic ecosystems in the Balkans.

Effects of Highly Acidic Volcanic Soils on Plant Ionome Related to Aluminum Tolerance Strategies: Aluminum Accumulator and Non-Accumulator Plants

Daisuke Aoshima et al

ionomics/ soil acidity/ solfatara

Graphical abstract: Objective: To elucidate plant nutrition strategies by comparing the ionomes of plants from solfatara fields (highly acidic soils) and non-solfatara fields. Key Finding: Ionomic profiles were classified into Al-accumulator and non-Al-accumulator groups rather than by field type.

Bioaccumulation and Trophic Transfer of Heavy Metals in Terrestrial Soil–Plant–Insect Food Chains Within Agricultural Systems: Patterns, Mechanisms, and Ecological Implications

Mohd Irfan Naikoo et al
▶️ x.gd/HNeOG8

Graphical abstract: Heavy metals can move from soils to plants and insects, influencing trophic interactions in terrestrial ecosystems. This review synthesizes evidence on the bioaccumulation, trophic transfer, and elimination of metals in soil–plant–insect food chains, highlighting key gaps relevant to ecological risk assessment.

Serpentine Biocrust Microbes Maintain Nitrogen Cycling Under Drought and Heavy Metal Stress

Sandra Barnard et al
▶️ doi.org/10.1111/1440...

biological soil crusts/ cyanobacteria/ moisture regime/ nitrifying archaea/ soil geochemistry

Graphical abstract: This study highlights the complex interplay between soil geochemistry and moisture availability in shaping microbial communities within wetter and drier serpentine and non-serpentine biological soil crusts. It demonstrates that both factors influence the structure of nitrogen-cycling microbial communities and the processes they mediate.

Dominance of Picea glehnii in the Serpentine Forests of Hokkaido: Perspectives for an Ecological Understanding

Florian Delerue et al

functional traits/ plant–soil feedbacks/ regeneration niche

Graphical abstract: We question why Picea glehnii dominates serpentine forests in Hokkaido. First, based on functional trait measurements and a comparison with another coniferous species present in the region, Abies sachalinensis, we report preliminary results consistent with better adaptation of P. glehnii to serpentine soils. We then discuss other non-exclusive hypotheses, based on the literature and observations of regeneration microsites, to provide a comprehensive view of the potential mechanisms involved. Adaptation to soil disturbance and the release of negative biotic interactions on serpentine soils in blowdown areas, promoting successful colonization and regeneration of P. glehnii, are likely complementary drivers. Finally, we propose future research directions to test these hypotheses and clarify the preferential distribution of P. glehnii and A. sachalinensis on different substrates.

Transfer of Potentially Toxic Metal(loid)s From Ultramafic Soils in a Tri-Trophic Food Chain Experiment

João Marcelo-Silva et al
▶️ doi.org/10.1111/1440...

Berkheya/ kale/ komatiite/ PTM/ Vredefort Dome

Graphical abstract: Potentially toxic metal(loid)s (PTMs) bioaccumulated across a plant-herbivore-predator food chain. Irrespective of soil concentrations, female crickets actively selected PTM-enriched leaves, while predatory mantids showed no developmental impairment. Trophic transfer of PTMs was rather influenced more by a function of intrinsic species traits than by environmental exposure.
