Giant Swamp Taro (Cyrtosperma merkusii) is a staple food crop in the Pacific, especially in the low lying atoll islands such as Tuvalu and Kiribati. This is owing to its ability to survive under poor soil conditions and harsh environments. However, as a result of the effects of climate change such as sea water inundation and intrusion into the fresh ground water lens, this crop is now under threat. To address this issue an adaption approach was taken whereby, Cyrtosperma merkusii was screened in vivo for salt tolerance. The epistemology followed random selection of two cultivars Ikaraoi and Katutu. These two cultivars were subjected to 0% (0 parts per trillion), 0.5% (5 ppt), 1% (10 ppt), 1.5% (15 ppt) and 2% (20 ppt) of salt in Yates’s advance seedling common potting mix. Both cultivars were able to tolerate salinity levels up-to 5ppt which is significantly more than the salt tolerance in glycophytes of 2.83 ppt. This research provides an insight into the variation of salt tolerance that may exist in C.merkusii gene pool, which can be used to adapt to natural disasters and buffer its impacts.

The paper demonstrates the fuzzy logic based smart distributed system to utilize the available energy optimally. We study the power system with two distributed sources of renewable energy like wind and solar together with normal power grid supply. Through the suitable allotter of the generation ratio from power sources, the distribution generation system, combined with battery bank, can provide user with reliable and constant electric power. Therefore a smart energy distributor is useful to supply energy to consumers such that their demand is supplied optimally depending available energy and battery status. In this work, a new distributor system is tested with fuzzy logic theory to satisfy the load demand constantly at the same time to keep the charging state of the battery at a safe level. Simulation results are also presented to illustrate the potential benefits of the smart distributor by maximizing the usage of renewable energy and depending less on the supply grid.

Kava (Piper methysticum Forst) and wild kava (Piper aduncum L.) were evaluated for their efficacy against root-knot nematodes. Plant materials were tested as soil additive in pot trials at 2% and 4% concentrations for 0, 1 and 2 week degradation periods. Effects on the root-knot nematode, M. incognita, and its host, tomato, were recorded. All the tested materials reduced the number of galls compared to the control. Generally, maximum gall suppression was achieved at higher concentration (4%) and with no degradation time. Gall suppression was directly related to concentrations of plant materials, but not with the degradation time after soil incorporation. Kava powder, kava peelings and kava kosa caused maximum gall suppression but were phytotoxic. Kava stem, kava leaf and wild kava leaf, on the other hand, resulted in lower gall suppression but enhanced plant growth. These plant species are good candidates for further trials as soil amendments.

The present study evaluated the antibacterial potentiality of hot aqueous and methanol solvent extract of mature leaves of Polyalthia longifolia (Sonn.) Thwaites (Magnoliales: Annonaceae) against six reference bacteria viz. Staphylococcus aureus MTCC 2940, Bacillus subtilis MTCC 441, Escherichia coli MTCC 739, Klebsiella pneumoniae MTCC 530, Proteus vulgaris MTCC 426 and Enterobacter aerogenes MTCC 111. A sensitivity test performed with commercially available sensitivity test disks resulted in the appearance of multiple drug resistance phenotypes as all the tested bacteria are resistant to amoxycillin, cloxacillin, penicillin G and ampicillin. Most effective antibiotic against bacteria includes ofloxacin against S. aureus and K. pneumoniae; cephalexin against P. vulgaris; ciprofloxacin against E. coli and B. subtilis; kanamycin against E. aerogenes. When antibacterial potentiality of hot aqueous and methanol solvent extract of mature leaves of P. longifolia was evaluated against the bacteria, highest antibacterial activity was observed against K. pneumoniae in both the extracts followed by E. coli in hot aqueous extract and B. subtilis in methanol extract as evident from MIC values. Chromatographic analysis of the methanol extract of P. longifolia revealed the presence of steroids, alkaloids, biterpenoids, carbohydrates, amino acids, essential oil, phenolics and flavonoids as major phytochemicals.

Time series of aerial photographs, which are reasonably widely available in the Pacific Island countries, provide a useful resource of geospatial data and can be used for the detection and quantitative assessment of spatio-temporal changes in the most dynamic coastal areas, which are often economically and culturally valuable, but also vulnerable to the effects of natural and anthropogenic stresses. Quantitative analysis, based on GIS and advanced image processing, is the most precise but time-consuming method. In many cases, visual detection and preliminary assessment of changes is a rational way to decide quickly whether more sophisticated techniques should be employed to map spatial changes in more detail. This paper elaborates on different techniques available for rapid change detection and analysis using time series of aerial photographs. The rationale and applicability of such methods are illustrated in a feasibility study that was implemented to detect changes since the mid-1960s in mangrove cover in the Korotogo area of the Coral Coast, on the southern coast of the main island of Fiji.

The extent of morphological variation among extant noni (Morinda citrifolia: Rubiaceae) genotypes was assessed using 58 polymorphic traits. A total of 39 mature noni trees were sampled from five sites within the vicinity of Lae, Morobe Province, Papua New Guinea. Cluster analysis identified five homogenous clusters, and was able to separate the three known botanical varieties namely, M. citrifolia var. citrifolia, M. citrifolia var. bracteata and M. citrifolia var. potteri as distinct morphotypes. Ordination of the data revealed traits such as young shoot pigmentation, stem diameter, angle of insertion of primary branch on main stem, stipule shape, heterostyly, occurrence of pistillate florets, fruit shape, occurrence of floral bracts, fruit width, and peduncle positioning at maturity as having greater contributions to the observed variation. Although the genetic nature of these traits is yet to be elucidated, occurrence of floral bract and fruit branching were observed to be transitional between the botanical varieties, and may shed light on their origins. The 58 descriptor states showed varying levels of polymorphism, however, the significant (P<0.01) correlations observed between numerous traits provide an element of caution in the development of a descriptor list, particularly when considering stability of the traits and the sample size. The results obtained in this study provided useful information for the standardisation of the developed descriptor list comprising of 49 polymorphic descriptor states, and for future diversity studies in noni.
利用58个多态性状对现有诺丽(Morinda citrifolia: Rubiaceae)基因型的形态变异程度进行了评价。在巴布亚新几内亚莫罗贝省莱附近的五个地点共取样了39棵成熟诺丽树。聚类分析鉴定出5个同质聚类，并能将已知的3个植物品种即citrifolia var. citrifolia var.苞叶型citrifolia var.苞叶型citrifolia var.苞叶型citrifolia var. potteri型citrifolia var.苞叶型citrifolia var.苞叶型citrifolia var.苞叶型和citrifolia var. potteri型区分开来。对这些数据进行排序发现，幼芽色素沉着、茎粗、一次枝在主茎上的插入角、托叶形状、花柱异质、雌蕊小花的出现、果实形状、花苞片的出现、果实宽度和成熟时花梗的定位等性状对观察到的变异有较大贡献。虽然这些性状的遗传性质尚未阐明，但观察到花苞片和果实分枝的发生在植物品种之间是过渡性的，并可能为它们的起源提供线索。58个描述符状态表现出不同程度的多态性，然而，在许多性状之间观察到的显著(P<0.01)相关性为描述符列表的开发提供了一个谨慎的元素，特别是在考虑性状的稳定性和样本量时。本研究结果为建立由49个多态性描述子状态组成的描述子列表的标准化提供了有益的信息，并为今后noni的多样性研究提供了参考。
