Carbon and forest

The dipterocarp forest is a featured ecological forest in the Central Highlands of Vietnam. However, humans and nature are disrupting the ecological balance structure of the forest. This study was conducted to evaluate the environmental efficiency of land management activities of the dipterocarp forest at Yok Don National Park by altering the dipterocarp forest ecosystem and soil organic carbon (SOC) stock for 2001–2020.

Mangrove forests, typically found along tropical and subtropical coastlines, have a crucial role in preventing coastal erosion, mitigating the effects of wave actions, and safeguarding coastal habitats. This study utilized PlanetScope mangrove forests and a Combined Mangrove Recognition Index (CMRI), which was suitable for detecting mangrove cover along the coast of Tien Yen district with an overall accuracy of over 93.0% and a Kappa coefficient greater than 0.90 for the selected years.

In the context of the word today, the consequences of climate changes are seriously happening. The rising sea level makes many land areas being gradually submerged. Extreme weather phenomena such as super typhoons or tsunamis are occurring more frequent and becoming more complicated and unpredicted. The forest fires have occurred continuously in recent years. The world largest rainforest - Amazon, which is considered as the green lung of the world, has seen a huge jump in the number of fires in recent years and this has greatly affected the living environment on Earth.

The present study aims to determine the role of the carbon source from mangroves to provide the organic matter in intertidal sediments by the stable isotopes approach. The present results suggested that mangroves are important in accumulating organic carbon and fine–grained sediments in the Tien Yen Bay, contributing important values to climate change mitigation and maintaining biodiversity in this area.

Mangrove forests are saline or brackish wetland environments, in which substrateusually anoxic due to waterlogging. This unique condition induces a high ability of this ecosystem in fixing and storing CO2, one of the greenhouse gases that contribute to global warming.

Mangrove forests are found along shallow shorelines with modest slopes where they receive freshwater runoff and nutrients from rainfall. They have been globally recognised as having a vital function in preventing coastal erosion, mitigating wave actions, and protecting coastal habitats and adjacent shoreline land-uses from extreme coastal events.

Air pollution is one of the most concerns problems currently. The air quality of urban areas depends directly and indirectly on urban vegetation because trees are identified to have ability to remove air pollutants. In this study, I-tree Eco model was used to quantify the removal ability of air pollutants from trees at selected universities in Ho Chi Minh City.

Therefore, it pointed out that improving the carbon content of forests cannot guarantee the preservation and promotion of plant biodiversity. Preserving plant diversity should therefore be a priority in forest resource management. With the results obtained, the article contributes to creating a robust scientific basis and helping managers plan and develop strategies for the conservation and development of forest capital in the study area.

The research article "Polyester production by halophilic and halotolerant bacterial strains obtained from mangrove soil samples located in Northern Vietnam" reports halophilic and halotolerant bacteria isolated from mangrove forests located in Northern Vietnam. Several of these bacteria were able to synthesize polyhydroxyalkanoates (PHAs). PHAs are polyesters stored by microorganisms under the presence of considerable amounts of a carbon source and deficiency of other essential nutrient such as nitrogen or phosphorous.

Vegetation and socio-economic data were recorded through bio-physical and semi-structured questionnaire survey, respectively from each HF. Respondents were asked to score each individual ES indicator on a 5-points Likert scale according to their relative importance, then the average score for three main ES were calculated. HF were classified into four classes based on its possessed area.

Maintaining and managing trees with different ecological plasticity under climate conditions aggravated by short-term variability are major challenges for foresters. Our aims were to investigate species-specific ecophysiological responses of canopy trees in a mixed Turkey oak forest during their early-phase regeneration. We measured plant carbon and water exchange with portable IRGA equipment under natural field conditions (canopy gap) and in a climate-controlled (standardized) environment.

Open-cast mining in tropical forests causes negative impacts on biodiversity and carbon storage. Postmining reclamation is therefore imposed to recover the vegetation despite the lack of understanding which indicators can be used to monitor the progress ofsuccession. This study proposes an integrated framework to assess the trajectory of vegetation succession in coal mining site in East Kalimantan, Borneo.

Studies on the effect of different nutritional compounds on antibiotic activity revealed that the highest antibacterial activity was obtained when 1% starch (w/v) was used as the sole carbon source along with mineral trace elements. Extraction and purification of TBG19NRA1 culture supernatant led to the isolation of a pure molecule with good antibacterial activity. The compound has been identified as the cyclic polyether lasalocid A on the basis IR, MS and 13C NMR data interpretation and comparison with reference data from literature.
