Potential and Determinants of Carbon Storage of Freshwater Swamp Forests

There has been an increase in carbon assessments across global ecosystems, but some ecosystem types remain woefully understudied, and freshwater swamp forests are one such ecosystem. Located between the mangrove swamp forest and the lowland forest ecosystems, freshwater swamp forest provides a corridor for the migration of flora and fauna between these ecosystems as well as being floristically unique. Swamp forests contribute to the provision of ecosystem services, are potential stores of carbon and important for climate regulation and biogeochemical cycling. However, this ecosystem has been steadily exploited, its extent has reduced, been degraded and is now confined to small pockets. As a result, its species like in most other old growth forests across the tropics, are not only threatened and fragmented, but the ecosystem services they provide are reduced. These changes have impacted the forest landscape adversely and reduced the former extensive ecosystem into mosaics of forest islands.
Since the use of the ecosystem are dependent on the management and ownership statuses of the forest lands, understanding the linkages between the management of the ecosystem and the services they provide is crucial to maximize ecosystem service potentials. We focus on highlighting the impact of forest use on the composition and the carbon storage capacities of the ecosystem; so as to better inform and promote the ecosystem’s conservation and its carbon potentials.

The capacity to which freshwater swamp forests across the region stored carbon seems to be on the decline following forest modification across most of the landscapes. This has become more acute because, the forests’ management and viability are dependent on individuals who mostly depend on the forests for sources of livelihood and barely consider issues of forest conservation.  This study found forest ownership and utilization can affect forest composition and its capacity to provide vital ecosystem services such as carbon storage. It is suggested that awareness of sustainable forest management techniques need to be advocated across both family owned and communally owned forests—in order to ensure that their carbon storage capacities are not hampered.

A Comparison of Methods Used to Determine the Oleic/Linoleic Acid Ratio in Cultivated Peanut (Arachis hypogaea L.)

Cultivated peanut ( Arachis hypogaea L.) is an important oil and food crop. It is also a cheap source of protein, a good source of essential vitamins and minerals, and a component of many food products. The fatty acid composition of peanuts has become increasingly important with the realization that oleic acid content significantly affects the development of rancidity. And oil content of peanuts significantly affects flavor and shelf-life. Early generation screening of breeding lines for high oleic acid content greatly increases the efficiency of developing new peanut varieties. The objective of this study was to compare the accuracy of methods used to classify individual peanut seed as high oleic or not high oleic. Three hundred and seventy-four (374) seeds, spanning twenty-three (23) genotypes varying in oil composition (i.e. high oleic (H) or normal/not high oleic (NH) inclusive of all four peanut market-types (runner, Spanish, Valencia and Virginia), were individually tested ...

Incorporation of High-Altitude Balloon Experiment in High School Science Classrooms

High-altitude balloon is a balloon, filled usually with helium or hydrogen that ascends into an area called “near space” or stratosphere. The most common type of high-altitude balloons are weather balloons. Other purposes include use as a platform for experiments in the upper atmosphere. Modern balloons generally contain electronic equipment such as radio transmitters, cameras, or satellite navigation systems, such as GPS receivers. The mission of the High-Altitude Balloon Experiment (HABE) is to acquire supporting data, validate enabling technologies, and resolve critical acquisition, tracking, and pointing (ATP) and fire control issues in support of future space-based precision pointing experiments. The use of high-altitude balloons offers a relatively low-cost, low-vibration test platform, a recoverable and reusable payload, worldwide launch capability, and a 'near- space' emulation of the future space systems operational scenarios. More recently, several university...

The Influence of Heated Soil in Crop of “Tamaris” Tomato Plants on the Biological Activity of the Rhizosphere Soil

Tomato is a plant with high heat requirements and sensitive to cold weather and frost. The optimum temperature for the growth of tomato plants is between 21˚C and 27˚C during the day and between 17˚C and 21˚C at night. The soil temperature is also very important for plant growth. The optimum soil temperature for tomato cultivation should be within the range 15˚C - 18˚C. Besides, the proper development of the root system depends on the optimal temperature of the soil. A temperature below 14˚C reduces and inhibits the growth of the root system and encourages the development of fungal and bacterial diseases. In this study, the authors aimed to evaluate the effect of heated soil on the population of bacteria, fungi and nematodes inhabiting the soil of tomato cultivar “Tamaris” growing in peat and coconut substrates. The experiment was carried out in 12 treatments and in 3 replications (one slab was one replication). The soils were tested in two different types of containers: cylinders...
