Summary: Accurate estimation of biomass and carbon stocks in mangrove forests is crucial for understanding their role in climate regulation. This study developed species-specific allometric equations and evaluated biomass allocation in two West African mangrove species. The new biomass models more accurately predicted biomass compared to existing models.

Summary: This study used metagenomics and genomics to analyze the abundance of genes associated with heavy metal resistance and tolerance in the rhizosphere microbiome of Avicennia germinans in a semi-arid mangrove in La Guajira, Colombia. The study identified a total of 28 genes associated with tolerance and 49 genes related to resistance to heavy metals. Genes associated with Cu tolerance, particularly cusA and copA, were the most abundant. The Vibrio fluvialis isolate showed the ability to tolerate Cu, Ni, Zn, and Cd. The study provides insights into the potential of mangrove microorganisms to tolerate and resist heavy metals and the influence of salinity on their abundance.

Summary: Mangroves are important in carbon sequestration but can also be sources of greenhouse gas emissions, especially methane. This study in Taiwan found that mangrove soils were significant sources of methane emissions, with Avicennia marina mangroves emitting much more than Kandelia obovata mangroves. Soil salinity and pH were key factors affecting methane emissions in K. obovata mangroves, while pneumatophore density was a major factor in A. marina mangroves. The root structure was found to affect greenhouse gas emissions from mangroves.

Summary: The study evaluates a local forest in Costa Rica, estimating it to be approximately 50 years old and capable of sequestering large amounts of carbon dioxide. Through measurements in two permanent plots, the campus forest was found to have sequestered 18,210 tons of CO2 in 2019.

Summary: This study developed biomass estimation equations and evaluated biomass partitioning patterns for Mongolian pine forests in the Mu Us Sandy Land. The results showed that diameter alone is a good predictor for branches and foliage biomass estimation, while stem estimation requires height inclusion. Mongolian pine allocates more biomass to the crown, and the biomass fractions of branches and foliage exhibit different trends with increasing tree size. These findings have important implications for ecosystem management and conservation in the Mu Us Sandy Land.

Summary: This paper presents a novel approach to map plant biodiversity in mangrove forests using satellite imagery and field plots. The results show that alpha- and beta-diversities account for different proportions of the total diversity, and the mapping accuracy varies among different satellite images. The red-edge and near-infrared spectral features are found to be informative for diversity mapping.

Summary: This study aimed to isolate and identify PUFAs-rich thraustochytrids from Indian mangrove ecosystems for their pigments, antimicrobial, and antioxidant properties. Two predominant isolates, Thraustochytrium sp. and Aurantiochytrium mangrovei, were found to produce PUFAs with high DHA content. A. mangrovei also exhibited the highest antioxidant activity.

Summary: This study provides insights into the adaptation mechanisms of Avicennia marina, a typical mangrove, to the coastal intertidal habitat. The researchers identified specific genes related to various biochemical processes, as well as a novel whole-genome duplication event that occurred during a global warming period. Comparative genomic and transcriptomic analyses revealed the distinct evolution and sophisticated regulations of A. marina to the intertidal environment. The findings have implications for understanding the evolution of mangroves and improving breeding efforts.

Summary: This study assessed the carbon sequestration potential of Avicennia marina in the Gulf of Kutch, Gujarat, India. The mean above-ground biomass was 96.9 Mg ha-1 and below-ground biomass was 19.6 Mg ha-1. The Gulf of Kutch had a mean total biomass of 116.5 Mg ha-1, with vegetation carbon stock of 54.1 Mg C ha-1 and soil carbon stock of 25.87 Mg C ha-1. Among the five creeks, Navlakhi had the highest total biomass and vegetative carbon stock.

Summary: This study focused on the fine-scale spatial genetic structure (FSGS) of Avicennia populations in the Philippines. It found that the proximity to open water and the narrowness of mangrove patches may affect their genetic diversity and structure. Coastal connectivity plays an important role in the long-term persistence of mangrove populations.

Summary: Studies on plant biomass allocation patterns on a global scale found that temperature, precipitation, plant height, and density jointly regulate leaf biomass and total biomass ratios. Biotic factors were found to have a larger effect than abiotic factors on plant biomass allocation.

Summary: The study estimated plant biomass in the mangrove forests of the Andaman Islands and found that the highest biomass was in Little Andaman, with Rhizophora apiculata being the largest contributor. The high vegetation carbon stock in the mangrove forests of the Andaman Islands is attributed to high structural complexity, precipitation rate, and fewer anthropogenic disturbances.
