A survey of plant species inhabiting oil palm trees was conducted in Zawlpui area of Serchhip district, Mizoram. The study area is a tropical potent agriculture zone, wherein small-scale business of Elaeis guineensis plantation is carried out by several farmers mainly within the gentle sloppy terrain. Oil palm with a rough bark harbors immense inhabitation by a variety plants, that rooted mostly on the debris at leaf base. Species diversity on the plant stem supposedly encourage insects and termites to establish herewith, thus causing harming to the tree. The sample stands within 400 m–800 m altitude were picked randomly. A total of 50 palm tree were accounted and all associated plants on the stem above 30 cm from the ground are all recorded. Species that cannot be identified on the site were pressed and observed at Botany Research lab, Pachhunga University College. The survey documented 38 vascular plant species which include 4 epiphytes and 1 non-vascular species of lichen, 1 bryophyte and 4 fungal species at that time. Invasive Peperomia pellucida and epiphytic pteridophytes Nephrolepis biserrata was found in most of the stand sample; however, Peperomia population decreases with the increasing elevation. Dynamics of inhabitant species diversity also correlate to location of tree. The study also established that diversity of inhabiting species was comparatively high on parts of the stem facing sunlight.

Abstract Elaeis guineensis Jacq. (Arecaceae), the oil palm tree, serves as a phorophyte for many different groups of organisms, someof whichhelp decompose organic matter comingfromthe organs of the tree itself or fromremainsof other plants retained in leaf sheaths. To study the myxobiota of E. guineensis, we examined living and dead trunks, leaves, bracts and inflorescences in the Gurjaú Ecological Reserve, in the township of Cabo de Santo Agostinho, Pernambuco, Brazil. Incidence and species abundance were determined in three Atlantic forest fragments. The reported species are listed herein, followed the known distribution of each species in Brazil, and which of them occur on palm trees. All of the subclasses and five orders were recorded and 22 species were added to the list of myxomycetes associated with oil palm trees in Brazil. The highest incidence value was recorded on dead leaves. Ceratiomyxa fruticulosa (O. F. Müll.) T. Macbr., Arcyria cinerea (Bull.)Pers. and Physarum compressum Alb.& Schwein. werethe most commonspecies, while Hemitrichia serpula (Scop.) Rostaf. ex Lister showed the highest levels of abundance and incidence, thus confirming its preference for the substrates provided by palm trees.

This field experiment was carried out to evaluate the weed species distribution in the experimental plots of an intercrop of juvenile oil palm trees (Elaeis guineensis Jacq.) with maize (Zea mays Linn.), okra (Abelmoschus esculentus Moench) and pepper (Capsicum annuum var. abbreviatum). This was carried out during the cropping season between July and October 2012. The crops were intercropped with the juvenile oil palm trees of about 3-years-old. The experiment was laid out in a completely randomized block design with five (5) replicates. The treatments comprised of intercropping distances of 1 m, 2 m and 3 m each for the three (3) crops (maize, okra and pepper) and a plot for each of the three (3) arable crops without oil palm trees as control. Weed species distribution was carried out in each of the plots to determine the Simpson’s Diversity Index (D), Simpson’s Index of Diversity (1-D) and Simpson’s Reciprocal Index (1/D). Weed species’ frequency, density, relative density, relative frequency, importance value, abundance, dominance and relative dominance were also computed from data collected at 3WAP and 6WAP. The results showed that the control plot has the highest weed species distribution at 3WAP having the lowest Simpson’s Diversity Index (D) of 0.0930. Okra plot has the least weed species distribution with the highest Simpson’s Diversity Index (D) of 0.2726. At 6WAP, the pepper plot has the highest weed species distribution having the lowest Simpson’s Diversity Index (D) of 0.1741. Control plot has the least weed species distribution with highest Simpson’s Diversity Index (D) of 0.2831.

Abstract: In this study we described the diet of Hylaeamys megacephalus (G. Fisher, 1814) and investigated the degree of individual variation in the diet of this species among the Amazon Forest and the oil palm plantation. We analyzed the stomach contents of 36 individuals, of whom 11 were collected in the forest and 25 captured in the palm oil palm plantation. The H. megacephalus diet consisted of 18 food items, of which 12 were animal composition and eight were vegetable composition. The niche amplitude of the species was narrower in the forest area (Baforest = 0.013) compared to the palm tree plantation area (Bapalm = 0.478). This shows that individuals have greater niche overlap in forest areas, while in the plantation areas the animals expand their food niche. In addition, the values of the mean of the individual diet in relation to the diet of the entire population were lower in the palm oil palm plantation environment (ISpalm = 0.164) than in the Forest environment (ISforest = 0.357), indicating a high specialization in the palm oil plantation. These results indicate a population mechanism to reduce intraspecific competition in response to scarce resources.

In this study, we report species diversity and endemism of the poorly known but highly diverse Seasonally Dry Tropical Forest (SDTF) flora of the Marañón valley in northern Peru. We characterise woody vascular plant species diversity across the valley in order to define the conservation value of the area at national and international level. Based on 32 rapid botanical inventories, 92 plots of 50 × 20 m, and a herbarium study across local and international herbaria, we report 440 woody vascular plant species of which 143 (33%) are endemic to the valley. Two centres of endemism within the valley are identified, each with clear elevational zonation of diversity. Data show that the Marañón valley is a good representative of Peruvian SDTFs as a whole, with an average of 56% SDTF species and 78% SDTF genera found in the one valley. The results show that there is wide variation in the set of dominant species across the valley, and that many local endemics are locally abundant unlike in neighbouring SDTFs where the dominant species are all geographically widespread. Our results demonstrate that the Marañón includes a rare combination of both nationally representative yet globally unique plant species, which makes the valley an ideal conservation target. The high level of endemism structured within elevational zones implies that conservation areas should be established across elevational zones in order to maximise the protection of this globally unique flora.

AbstractFibers obtained from different parts of the oil palm tree (Elaeis guineensis) have been under investigation for possible use in construction. Studies have been carried out investigating the engineering properties and possible applications of these fibers. However, the experimental methods employed and the values of mechanical and physical properties recorded by various authors are inconsistent. It has therefore become necessary to organize information which would be useful in the design of oil palm fiber cement composites and help researchers and engineers make informed decisions in further research and application. This review provides information about fibers from different parts of the oil palm, their properties, enhancement techniques, current and potential application in cement composites.

During a 1-year cycle the acidic, ethyl acetate soluble gibberellinlike activity in the phloem sap of the emergent male inflorescence of the oil palm tree (Elaesis guineensis Jacq.) was assayed with barley half-seeds after separation on paper chromatography. Gibberellinlike substances which cochromatograph with gibberellic acid 3 were translocated to the male emerging inflorescence stalk. Their quantity was maximal (45 μg L−1 of sap) in late November, and minimal (1.5 μg L−1 of sap) during March to August.

Vascular plant species diversity in the ravines of the southern Finger Lakes followed the ravine-side gradient and vegetation characteristics described by Lewin (1974). Bottom and lower-slope mesophytic communities were very rich in species, middle-to-upper hemlock stands were very poor in species, while the upper oak stands were again somewhat richer. Dominance followed an inverse pattern, being lowest in the low, mesophytic stands and high in the hemlock stands. The amount of hemlock in the canopy appeared to have an effect on diversity.

The oil palm tree (Elaeis guineensis Jacq.) originates from West and Central Africa, and it is cultivated in Malaysia for its oil-producing fruits. Malaysia is the world’s second largest palm oil producer and the world’s largest exporter to date. Consequently, the Malaysian oil palm industry constantly generates a huge amount of biomass with the major contributor being the leaves. A large percentage of these leaves remain underutilized, making them a promising source of raw materials that can be converted into value-added products. The present review summarizes and discusses the flavonoid composition, total phenolic and flavonoid content, and the in vitro and in vivo pharmacological properties exhibited by the extracts of the leaves of E. guineensis. The purpose of this systematic review is to highlight the potential of valorizing the leaf extracts of the oil palm tree as pharmaceutical and cosmeceutical agents.
