Soil pollution with petroleum products is an urgent public health and environmental problem. Therefore, innovative solutions for cleaning soils contaminated with petroleum products are needed. One such solution is rhizodegradation, which is recognized as a sustainable and effective method of soil remediation. Much of the previous research was done with monocultures, therefore the effects of different combinations of plants on the removal of petroleum products remain ambiguous. These studies evaluated three different herbaceous plant mixtures for the removal of total petroleum hydrocarbons (TPHs) from contaminated soil. Promising results were obtained. Selected herbaceous plant species and their mixtures can be successfully grown in contaminated soil at a contamination level of 6,817 mg/kg TPH DW according to the selected cultivation strategy. After applying a complex of biotechnology and agronomic solutions, the morphological and morphometric indicators revealed the good adaptability and tolerance of the selected herbaceous plants to growing in contaminated soil. After two years of pot testing application of different mixtures of herbaceous plants, the TPH (C-C) removal potential reached 85-90%.

Aims: Understanding the response of herbaceous plants to habitat changes and the mechanisms of vegetation succession is crucial to the theoretical foundation of the conservation of local vegetation.
Methods: Plots were established at elevations of 1900-2200m, 2200-2500m, and 2500-2800m on both shady and sunny slopes. Four statistical methods 2×2 contingency table χ-test, Spearman's rank correlation coefficient, AC joint coefficient, 17 and Ochiai Index, were employed to analyze the species composition and interspecific associations within each elevation band and aspect.

Introduction: Secondary forests and coffee cultivation systems with shade trees might have great potential for carbon sequestration as a means of climate change adaptation and mitigation. This study aimed to measure carbon stocks in coffee plantations under different managements and secondary forest systems in the Peruvian Amazon rainforest (San Martín Region).
Methods: The carbon stock in secondary forest trees was estimated using allometric equations, while carbon stocks in soil, herbaceous biomass, and leaf litter were determined through sampling and laboratory analysis.

The broad-scale inventories of alien species reveal macroecological patterns, but these often fall short in guiding local-level management strategies. Local authorities, tasked with on-the-ground management, require precise knowledge of the occurrence of invasive species tailored to their jurisdictional boundaries. What proves critical at the local scale may not hold the same significance at national or regional levels.

A common assumption of plant hydraulic physiology is that high hydraulic efficiency must come at the cost of hydraulic safety, generating a trade-off that raises doubts about the possibility of selecting both productive and drought-tolerant herbaceous crops. Wetland plants typically display high productivity, which requires high hydraulic efficiency to sustain transpiration rates coupled to CO uptake. Previous studies have suggested high vulnerability to xylem embolism of different wetland plants, in line with expected trade-offs.
