“…Previous investigations at the Tampamachoco coastal lagoon reported that the absence of live pneumatophores of dead mangroves was an important factor causing higher CH 4 emissions from soils (Romero‐Uribe et al 2021). Due to the absence of live pneumatophores, oxygen could not be transported to the roots of mangroves to inhibit methanogenesis.…”

“…Higher CH 4 emissions due to the loss or degradation of mangrove vegetation have been reported in some regions. CH 4 emissions from soils of degraded mangrove forests were up to ninefold higher than those of preserved mangroves during the rainy season in the Tampamachoco coastal lagoon, Mexico, southwest of the Gulf (Romero‐Uribe et al 2021). Along the coast of the Gulf of Carpentaria, Australia, eightfold more CH 4 fluxes were observed from tree stems of dead mangroves compared to living trees (Jeffrey et al 2019), and 35% higher sediment CH 4 emissions were observed from dead areas than living areas (Sippo et al 2020).…”

“…On the other hand, we need to consider the offset of greenhouse gas emissions to carbon storage for a precise evaluation of the function of ecosystem change. Unlike the eastern and southern coasts of the Gulf of Mexico (Oremland 1975; Chuang et al 2017; Romero‐Uribe et al 2021), few studies on CH 4 emissions in this region, the northwest coast of the Gulf, have been reported. Further consideration of CH 4 emissions is provided with evaluation of the death of a large area of mangroves at Aransas Bay caused by the freezing event between 14 February and 17 February, 2021 (Fig.…”

Mangrove ecosystems with high sediment deposition and active carbon cycling are a source of methane (CH 4 ) to the coastal atmosphere. We investigated diurnal and seasonal variations in CH 4 emissions from a subtropical mangrove estuary in southern Texas, northwest Gulf of Mexico. Tidal processes, amplitude (spring vs. neap tides) and topographic characteristics are crucial factors controlling CH 4 cycling in mangrove creeks. Higher CH 4 concentrations were observed during the ebb in spring tides due to the combination of processive export of CH 4 along the creeks during ebb tides and the addition of porewater CH 4 in upper intertidal sediment under water inundation in spring tides. The annual CH 4 emissions offset approximately 0.15% of the carbon stock in normal years, indicating that these mangrove creeks are a weak CH 4 source. However, significantly elevated CH 4 emissions were observed from mangrove dieback after the extreme cold-freezing event in February 2021. The average CH 4 flux from the mangrove creeks (126.1 AE 128.3 μmol [m 2 Ád] À1 ) increased 45% in 3 months after mangrove die-off in comparison with the overall average in normal years (87.0 AE 64.4 μmol [m 2 Ád] À1 ). It is obvious that the previous small CH 4 offset of the healthy mangrove forest was enlarged by the dieback event.Because the mangrove forests in this study live close to the limit of their survival range, our study highlights the important management considerations for blue carbon projects in vulnerable areas.

“…Mangrove areas are wood/timber producers, feeding–nesting ground for birds, and consumable fishery commodities such as fish and shellfish [ 10 , 11 ]. On the global scale, the mangrove area is a main natural contributor in managing the climate in complex ways, such as its carbon flux mechanism and sequestration scheme [ 12 , 13 ]. However, the mangrove area hides its useful function on a smaller scale, especially for human merit.…”

Exploring the Mangrove Fruit: From the Phytochemicals to Functional Food Development and the Current Progress in the Middle East

Nowadays, the logarithmic production of existing well-known food materials is unable to keep up with the demand caused by the exponential growth of the human population in terms of the equality of access to food materials. Famous local food materials with treasury properties such as mangrove fruits are an excellent source to be listed as emerging food candidates with ethnomedicinal properties. Thus, this study reviews the nutrition content of several edible mangrove fruits and the innovation to improve the fruit into a highly economic food product. Within the mangrove fruit, the levels of primary metabolites such as carbohydrates, protein, and fat are acceptable for daily intake. The mangrove fruits, seeds, and endophytic fungi are rich in phenolic compounds, limonoids, and their derivatives as the compounds present a multitude of bioactivities such as antimicrobial, anticancer, and antioxidant. In the intermediary process, the flour of mangrove fruit stands as a supplementation for the existing flour with antidiabetic or antioxidant properties. The mangrove fruit is successfully transformed into many processed food products. However, limited fruits from species such as Bruguiera gymnorrhiza, Rhizophora mucronata, Sonneratia caseolaris, and Avicennia marina are commonly upgraded into traditional food, though many more species demonstrate ethnomedicinal properties. In the Middle East, A. marina is the dominant species, and the study of the phytochemicals and fruit development is limited. Therefore, studies on the development of mangrove fruits to functional for other mangrove species are demanding. The locally accepted mangrove fruit is coveted as an alternate food material to support the sustainable development goal of eliminating world hunger in sustainable ways.
