Glechoma Longituba

This article studied the role of ground cover plants improving environmental factors mainly taking Glechoma longituba (Nakai) Kupr and Viola philippica as examples. The abilities of carbon fixation, oxygen release and transpiration heat absorbtion and dust-removal were measured ,and the results were shown:1. The ability of carbon fixation, oxygen release and transpiration heat absorbtion of Glechoma and V.philippica is in moderate leavel ;2. Planting G.longituba 28m2, or V.philippica 37 m2, can supply oxygen for an adult one day including gas and breathing oxygen consumption;3. The daily heat absorbtion of 1 m2G.longituba is equivalent to air conditioner working 5.79h, and V.philippica , 5.2h;4. 100m2G.longituba can retain dust 2.86kg per year , while V.philippica, 13.63kg per year. Which shows that ground cover plants have a great ability to improve the environment.

Thinning forest stands changes biotic and abiotic conditions, subsequently altering understory communities including their photosynthetic characteristics. We investigated the effects of thinning (25% basal area decrease) in a subtropical Pinus massoniana Lamb. plantation at two post-thinning times: 0.5 years (PT0.5) and 2.5 years (PT2.5). Thinning (PT0.5 and PT2.5) significantly increased understory density (+104.9% and +142.4%, respectively), aboveground biomass (+191.1% and +239.2%, respectively), the Shannon–Wiener index, and the Pielou index and decreased the Simpson index (p < 0.05). Species richness significantly increased at PT0.5 and decreased at PT2.5 (p < 0.05). Photosynthetic characteristics of new and old leaves of three dominant species (Woodwardia japonica (Linn. f.) Sm., Dryopteris championii (Benth.) C. Chr., and Dicranopteris dichotoma (Thunb.) Bernh.) showed different variations at 0.5 and 2.5 years after thinning, depending on their various adaptive strategies. Generally, thinning improved leaf carbon fixation capacity of these dominant plants (except W. japonica old leaves). Leaf photosynthetic characteristics of these species exhibited some common changes with respect to leaf morphological attributes and chlorophyll content. Thinning increased new-leaf length (or width) and reduced old-leaf chlorophyll b concentration at PT0.5 but reduced new-leaf length, specific leaf area, and all-leaf chlorophyll concentration at PT2.5. In conclusion, thinning is a useful tool for increasing understory abundance and carbon fixation capacity of some fern species.

The mangrove ecosystem holds a lot of potentials to be utilized by local communities in the Riau Coastline. Therefore, this study was carried out to assess the biodiversity of flora and fauna in the Riau Coastline mangrove ecosystem and its impacts on local communities. The transect was performed to identify soil conditions, distribution, and the dominance of flora species, while field observations and interviews with residents were conducted to determine the presence of fauna and discover the ecosystem’s benefit to the local community's economy. Based on the results, Rhizophora mucronata and Rhizophora apiculata has the highest relative dominance (RDC) and important value index in all observed stations. On the other hand, the fish/water biota species has the highest diversity and have economic that mostly serve as a catch for local fishermen. Ecotourism is also encouraged to boost the community's economy and aid ecological learning for sustainability purposes. The mangrove ecosystem's existence remains sustainable because fisheries are the main commodity, however, logging is less desirable as a source of income.

Mangrove is the largest ecosystem in Berbak-Sembilang National Park (BSNP) South Sumatra. Mangrove has capability to absorb carbon dioxide through photosynthesis then store it in biomass, that known as Carbon sink. The purpose of this research was to estimate the ability of carbon fixation through the photosynthesis mechanism in the mangrove area of BSNP South Sumatra. This study was conducted in July-August 2017, at 12 observation stations. Data of carbon fixation through photosynthesis was estimated by using Leaf Area Index (LAI) method. The estimation of carbon fixation by photosynthesis was done for 17 dominan mangrove species in BNSP South Sumatera. The average amount of carbon absorbed by mangrove vegetation through photosynthesis mechanism in BNSP South Sumatera was 204.91 kg/ha/day. Avicennia marina and Rhizophora apiculata were the mangrove community that showed highest capability to absorb carbon through photosynthesis around 553.43 kg C/ha/day and 401.99 kg-C/ha/day, respectively. Individually, B. cylindrica had the highest capability of carbon fixation by photosynthesis mechanism (10.95 kg-C/ha/day). Our research recommended three mangrove species (A. marina, R. apiculata and B. cylindrica) for restoration species to increase carbon sink in BNSP South Sumatera based on their photosinthesis performances.

Disposal of industrial wastewater has resulted in increased concentration of heavy metals (HMs) along the coastline of Malaysia. However, little is known about the accumulation capacity of HMs by Rhizophora apiculata in Matang Mangrove Forest Reserve (MMFR) Malaysia. The aim of this study is to measure the concentration of HMs in different ages of mangrove forests. In this study, 15 and 80-year old trees of Rhizophora apiculata were selected for experimentation. Thirty samples of leaves, roots and sediments were analyzed to measure the concentration of HMs in 15 and 80-year-old trees. The measured concentrations of copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) in leaves, roots and sediments were used to compare bio- concentration and translocation factor between the abovementioned two age groups. Concentration of Mn came out to be significantly higher in leaves than in sediment. This suggested that Rhizophora apiculata was an efficient Mn-extractor. On the other hand, it was found less efficient in extracting heavier metals (Fe, Cu and Zn) from the sediment, as their concentration was lower in leaves and roots as compared to sediments. The translocation factor was highest for Mn, indicating high mobility of Mn from roots towards the leaves. Bio-concentration factor was also found highest for Mn (3.52) followed by Zn (1.88), Cu (1.33) and Fe (0.26). Therefore, it can be concluded that Rhizophora apiculata is more efficient in extracting Mn as compared to Zn, Cu and Fe.
