Abstract This study is presenting results from an experiment with two well-known dye plants and their interaction with different types of textile fibres. Briefly, fresh and dry inflorescences of Tagetes patula and dry inflorescences of Tanacetum vulgare were used for the preparation of a dyeing bath. Then, different samples of cloth (made from natural plant fibres (wool), artificial fibres (sloter and ortalion), both artificial and plant fibres (canvas) and natural animal fibres (wool)) were immersed into the hot dyeing baths. Results showed that both chosen plant species are suitable for textile dyeing, but they differ in colour density.

Abstract Background: There are many medicinal applications of natural plant remedies. Several illnesses are still being treated by Palestinian people using medicinal plants. This research was intended to study the use of natural plants to treat different types of Respiratory tract disorders. Method: In the Northern part of Palestine, an ethno-pharmacological study of medicinal plants used to treat respiratory diseases has been carried out. A questionnaire was circulated to 120 informants. The details gathered included the names of the plants, the parts used, the diseases for which the products were used, as well as the method of preparation. To evaluate results: percentages (%), Fic (factor of informant consensus) and FL (fidelity-level) was calculated. Results: A total of 120 participants were included in the final analysis. The highest percentage of herbal use was reported for flu (103 participants) followed by cough, while the lowest percentages of users were in bronchitis management. The study showed that 31 plant species of 19 families were used for respiratory disorders. 6 species are from Lamiaceae family, while 3 species from Apiaceae family, two species are from Amaryllidaceae, Fabaceae, Myrtaceae, Rutaceae and Zingiberaceae , while the rest of the families only one species was mentioned by the participants, The pieces used most commonly were leaves and fruits. Decoction was the technique of preparation and was taken as a hot drink.Chamomile, mint, sage , lemon and ginger all were in treatment of all of the five respiratory diseases.Conclusions: The information provided on medicinal plants, with maximum percents & FL values can serve as basic data for further research to identify the active biological ingredients in these plants., and to develop new drug preparations for the treatment of disorders of the resapiratory system.

Ecological Basis

In simple terms, a phytosociological survey is a group of ecological evaluation methods whose aim is to provide a comprehensive overview of both the composition and distribution of plant species in a given plant community. To understand the applicability of phytosociological surveys for weed science, as well as their validity, their ecological basis should be understood and the most suitable ones need to be chosen, because cultivated fields present a relatively distinct group of selecting factors when compared to natural plant communities. For weed science, the following sequence of steps is proposed as the most suitable: (1) overall infestation; (2) phytosociological tables/graphs; (3) intra-characterization by diversity; (4) inter-characterization and grouping by cluster analysis. A summary of methods is established in order to assist Weed Science researchers through their steps into the realm of phytosociology.

Carpobrotus Edulis

<p>Biological invasion by non-native plant species has often been cited as a cause of native biodiversity loss. While the outcome of species invasions depends on interactions between exotic and resident native species, most studies of biological invasions have focused solely on the direct negative impacts of non-indigenous species on native biota. Although investigations of the role of competition in shaping natural plant communities were dominant in the previous generations and are still popular, more recent experimental research has uncovered the striking influence of facilitation on community dynamics. This thesis aims to investigate competitive and facilitative influence of the invasive South African iceplant (Carpobrotus edulis) on Spinifex sericeus, a native foredune grass species, with particular reference to implications of these interactions for dune restoration in New Zealand. It further explores the growth rates, substrate preferences and mating systems of the exotic and native iceplant taxa found in New Zealand. I begin by briefly outlining the influence of competition and facilitation on natural plant communities with reference to the role of facilitation in eco-restoration. I also give a few examples where exotic species have been found to facilitate native ones. Secondly, a neighbour removal experiment was conducted on coastal sand dunes with the main aim of studying the effects of Carpobrotus edulis on establishment of Spinifex sericeus at the foredune region. Finally, I compared the growth rates of the most widely distributed iceplant taxa in New Zealand in different substrates and the breeding systems of the exotic Carpobrotus.  Examples abound in literature of exotic plant species facilitating native ones especially in forestry. In the neighbour removal study, Carpobrotus edulis protected Spinifex seedlings against storm erosion, sandblasting and salt sprays while at the same time suppressing its leaf production. Suppression of Spinifex leaf production was more pronounced at top of the dune where stress elements is presumably more benign. There was no evidence of allelopathic suppression of Spinifex by C. edulis. Only Carpobrotus chilensis displayed some level of substrate preference by putting on relatively lower biomass in gravel. The exotic Carpobrotus spp. put on greater dry matter content than the native Disphyma australe and the Carpobrotus-x-Disphyma hybrid. The hybrid displayed a faster vegetative growth rate whereas D. australe allocated relatively more biomass to the roots than the shoot. Both Carpobrotus spp. are self compatible and highly capable of intrageneric and intergeneric hybridisation. Mass removal of the existing exotic iceplant stands from foredunes along high energy coasts is not advisable as they serve as useful stabilisers. The intergeneric hybrid is sexually sterile with sparsely spread stolons that could allow co-occurrence with other species and therefore is more suitable for foredune stabilisation. However, more research needs to be conducted on the ecology of the intergeneric hybrid.</p>

Ritter & Salamini (1996) presented a systematic account of two-point linkage analysis in allogamous diploid plant species. Vowden et al. (1995) described an alternative approach that is implemented in a computer program LINKEM. This paper describes how the latter approach has been extended to three-point linkage analysis, and implemented in a new program LINK3EM that is available from the authors. The essence of the approach is for the computer program to derive the appropriate form of analysis for a specific cross from its ‘knowledge’ of the most general type of cross that can arise. This avoids the need for programming specific codes for the many different types of cross that can arise. The program allows different locus orderings and parental phases to be compared. The Haldane or Kosambi map functions can be specified, although it is also possible to estimate all three pairwise recombination fractions without any assumed map function.

This chapter examines ecological opportunities that are available to species in various positions within a biological community, with particular emphasis on identifying the criteria necessary for an ecological opportunity to exist. Before discussing what performance capabilities a species must have to fill different types of ecological opportunities and what is required for invasibility of species into different functional positions in a community, the chapter considers the different frameworks that have been used to model species interactions. It then describes resource and apparent competition to show how resource availability from below and predation pressure from above can affect the types of species that can exploit specifc ecological opportunities. It also analyzes communities with three trophic levels, intraguild predation or omnivory, mutualism, the mechanisms that foster coexistence between one plant species and one pollinator species, and the case of one plant species with multiple pollinators.

Catalytic Role

The main purpose of the study was to document the medicinal animals and plants used by the unique ethnic group; ‘Balami’, native of Okharpauwa VDC of Nuwakot district. The information was collected in the area using an integrated approach of zoological and botanical collections, group discussions, interviews and questionnaires. It enumerates an account of ethnography with the list of 65 animal species belonging to 31 orders, 46 families and 62 genera. Out of which 55 species are wild and 10 species are domesticated. The Balami utilize these animals mainly for food, medicine, companion, ceremony, agriculture etc. They use 15 species of animals for medicinal purpose among which 13 are wild and 2 are domesticated to cure 16 different types of diseases. Balami have brought altogether 185 different plant species into use. Among them 80 species are brought from the local forest, 87 species are cultivated and 18 species of the plants are purchased from the nearest market. These plant species are included under 65 families and 151 genera. They use 45 different plant species to cure 55 different diseases out of which 32 are wild, 12 are cultivated and 1 is purchased from the remote area. The present inventory will play a catalytic role for implementation of development programs in the region, recommendations of the conservation and sustainable use based on indigenous knowledge from the elder to the younger generations.Journal of Institute of Science and Technology, 2014, 19(2): 79-85

Odorous Compounds

Ambergris, an excretion product of sperm whales, has been a valued agent in the formulation of perfumes. The composition of ambergris consists of two major components: 40–46% cholestanol type steroids and approximately 25–45% of a triterpenoid known as ambrein. Ambergris undergoes oxidative decomposition in the environment to result in odorous compounds, such as ambraoxide, methylambraoxide, and ambracetal. Its oxidized form, ambrafuran (IUPAC name: 3a,6,6,9a-tetramethyl-2,4,5,5a,7,8,9,9b-octahydro-1H-benzo[e][1]benzofuran), is a terpene furan with a pleasant odor and unique olfactive and fixative properties. The current state of the fragrance industry uses ambrafuran materials entirely from synthetic or semisynthetic sources. However, natural compounds with the potential to be converted to ambergris-like odorants have been extracted from several different types of plants. Here we review plant terpenoids suitable as starting materials for the semisyntheses of ambrafuran or intermediates, such as ambradiol, that can be used in biocatalytic transformations to yield ambrafuran.
