This study aimed to assess the condition of the Dasun estuary, Indonesia, from the influence of heavy metals Cr, Cd, and Pb that accumulated in sediments and beach morning glory vegetation (Ipomoea pes-caprae). The results showed that the metal concentrations of Cr, Cd, and Pb in the sediments were 3.39-5.29 mg/kg, 0.21-0.29 mg/kg, and 5.36-6.87 mg/kg, respectively. The concentrations of metals that accumulated in the tissue of entire plants were 0.98-1.22 mg/kg (Cr), 0.31-0.40 mg/kg (Cd), and 0.94-1.23 mg/kg (Pb). Dasun estuary is still in the safe category for the living habitat, even though the concentration of Cd was relatively high and was estimated to originate from batik industry waste. The vegetation of Ipomoea pes-caprae was found to have a high ability to absorb Cd; thus, it can be used as a bioindicator for heavy metals in the environment.

Invasive alien plant species (IAPS) pose a serious threat to overall plant biodiversity across the globe. Nepal's national parks and protected areas are not devoid of the impact of IAPS. Unfortunately, there is a substantial gap in knowledge regarding the extent and impact of invasion in protected areas of Nepal.

Coastal wetland ecosystems make an important contribution to the global carbon pool, yet their extent is declining due to aquaculture-related land use changes. We conducted an extensive investigation into the carbon stock and area coverage of macrophytes in a tropical coastal Ramsar wetland, Kolleru in Andhra Pradesh, India. A total of 72 quadrats of size 1 × 1 m were laid in the wetland, 19 species of macrophytes were collected and analyzed for carbon content using a CNHS analyzer.

Planting vegetation on slopes is an effective way of improving slope stability while enhancing the aesthetic appearance of the landscape. However, plants growing on slopes are susceptible to natural drought stress (DS) conditions which commonly lead to water deficit in plant tissues that affect plant health and growth. This study investigated the photosynthetic gas exchange, plant water status and proline accumulation of three tropical perennials namely Clerodendrum paniculatum, Ipomoea pes-caprae and Melastoma malabathricum after being subjected to DS and re-watering (RW).

Serra dos Carajás harbors a unique open plant community in Amazonia, known as vegetation, with several endemic species coexisting with the potential threat of large-scale iron ore mining. In this sense, Convolvulaceae occur in a wide variety of canga geoenvironments with multiple flower visitors, but the scarcity of data on its pollen morphology prevents the correct association between Convolvulaceae species with floral visitors, as well as the precise identification of their habitats throughout the Quaternary. Therefore, this study aims to contribute to the taxonomic knowledge and refinement of the identification of insect-plant networks of endangered plants, including .
