Chrysoporthe cubensis‐Induced Wilting in Eucalypt Mini‐Stumps: In Vitro Fungus and Disease Development

open access: yesJournal of Phytopathology, Volume 174, Issue 1, January/February 2026.
ABSTRACT Chrysoporthe cubensis was reported to cause wilting that later progressed to dieback and death in eucalypt mini‐stumps. This study aimed to evaluate the influence of various factors on the in vitro development of C. cubensis and to reproduce the wilting symptoms in eucalypt following artificial inoculation. Conidial production by C.

Ipso facto clauses in cross‐border insolvency: From STX Pan Ocean to Hanjin Shipping and beyond

open access: yesInternational Insolvency Review, Volume 34, Issue 3, Page 793-821, Winter 2025.
Abstract This article examines the enforceability of ipso facto clauses in cross‐border insolvency, with a focus on the landmark STX Pan Ocean case. This case highlighted divergent judicial approaches and the critical role of legal frameworks in conflict‐of‐laws scenarios, as evidenced by the contrasting outcome in the Hanjin Shipping case.

Assessment of Elemental Geochemistry: Enrichment and Mobilisation in Acid Sulfate Soils in Southeast Brazil

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 3, May–June 2025.
ABSTRACT The spatial distribution of acid sulfate soils is influenced by coastal processes, and due to their location, these soils can accumulate significant amounts of trace elements. This study assesses the horizontal and vertical distribution of major elements (Ca, Mg, K, Al, Fe, S), minor elements (P, Ti, Mn), and trace elements (Ba Co, Cu, Cr, Mo,

Acid Sulfate Soils and Their Impact on Surface Water Quality: A Case Study in Southeast Brazil

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 3, May–June 2025.
ABSTRACT Re‐flooding of previously drained and oxidised acid sulfate soils (ASSs) can stimulate reduction processes while decreasing soil acidity, thereby mitigating the harmful effects of acidity. The aim of this study is to explore the pedogenesis of ASSs in a tropical climate and to assess the impact of ASS on surface water quality at the end of the

Mineralogical Changes in Acid Sulfate Soils With Thionic Horizons: Insights From the Delta Doce River, Brazil

open access: yesEuropean Journal of Soil Science, Volume 76, Issue 2, March–April 2025.
ABSTRACT Acid sulfate soils (ASS) with sulfide minerals (i.e., contain sulfidic materials) are widely distributed in both coastal and inland regions, and if exposed to air, the oxidation of sulfide minerals results in the production of sulfuric acid with the formation of thionic horizons (pH < 4) along with profound mineralogical changes.
