Background & Aim: Knowledge of the traditional application of plants is declining faster than the plants themselves; this study was conducted to record and store the local knowledge and cultural outcomes for using the medicinal plants in treating diseases in Mobarakeh region, Isfahan, Iran. Experimental: This study has done based on applying the desert survey, information of local people, and ...
Values-based indicators of risks to Indigenous health have the potential to improve the accuracy and quality of a wide range of decisions affecting Native lands and cultures. Current health impact assessment approaches often omit important health priorities rooted in the history, social structures, and cultural context of Indigenous communities. Insights and methods from the decision sciences c...
AMS 14C dating of Holocene estuarine deposits: consequences of high energy and reworked foraminifera
Benthic foraminiferal species were used to AMS date Holocene sediments adjacent to transgressive overlap boundaries (TOB) in two high energy estuaries in North Spain. It had previously been recognised that the foraminifera could be divided into indigenous and exotic components. Whereas it was known that the exotic forms had been transported into the estuaries from the adjacent inner shelf, it w...
The present study was undertaken to evaluate the microbiological quality of indigenous dahi from eastern Nepal. A total of 39 indigenous dahi samples were collected from sixteen districts of eastern Nepal and analyzed. Results revealed the mean yeasts and mould count to be 20.5×10±7503, coliform count 65±42, S. aureus197±65 and total viable bacterial count 227×10±17250 cfu/g. Total viable bacte...
The teeth and oral epithelial surfaces are colonised by a great variety of bacte rial species. A partial list of indigenous (autochthonous) organisms found in the adult human mouth is shown in Table 11 (Gibbons and van Houte, 1975; Gibbons and van Houte, 1978; Rose bury, 1962; Socransky and Haffajee, 1988; van Houte, 1980). Characteristi cally, such indigenous bacteria are well adjusted to t...
Saccharomyces cerevisiae and non-Saccharomyces yeasts in grape varieties of the São Francisco Valley
The aims of this work was to characterise indigenous Saccharomyces cerevisiae strains in the naturally fermented juice of grape varieties Cabernet Sauvignon, Grenache, Tempranillo, Sauvignon Blanc and Verdejo used in the São Francisco River Valley, northeastern Brazil. In this study, 155 S. cerevisiae and 60 non-Saccharomyces yeasts were isolated and identified using physiological tests and seq...
We have developed a simple system to clone indigenous Rhizobium plasmids into E. coli. The strategy consists of three matings: the first is to insert Tn5 in the plasmid to be cloned, the second incorporates the integrative vector into the inserted Tn5 in the native Rhizobium plasmid, and the last mating transfers the target plasmid directly into E. coli. This mating-based system was successfull...
Introduction of non-indigenous species into a well-established ecosystem can be detrimental, resulting in both ecological and economical damage. Two specimens of giant mud crab, Scylla serrata were found for the first time in two geographically distinct mud crab landing sites (Matang Mangrove Forest Reserve, Perak and Kota Marudu Mangrove Forest, Sabah) in Malaysia. Their identities were confir...
In this study we report the first animal invasion, to our knowledge, into Lake Malawi. The colonizer is a non-native morph of the gastropod Melanoides tuberculata that differs substantially in external shell characters from co-occurring indigenous forms. However, because the species possesses extensive within-Africa geographical variation in shell morphology, it was unclear whether the invasion...
Invasive species are increasingly being recognized as a driver of global environmental change, causing both economic and environmental damages (Mack et al., 2000). These effects will likely be exacerbated as the rate of introduction of exotic species worldwide accelerates in conjunction with global trade (Hulme, 2009). Not surprisingly, there is consensus in the scientific community that societ...
