Heroic worldwide conservation efforts have made great strides in saving China’s endangered national treasure, the giant panda. Now, in China, there are over 65 giant panda reserves that have been established and three large breeding centers. But despite these efforts, just 1,596 pandas remain in the wild. Breeding programs in conservation centers and zoos hope to save the panda by improving gen...
cumin (cuminum cyminum l.) is one of the most important cultivable medicinal plants in iran and today, it is the second most popular spice in the world after black pepper. it is essential to know the relationships between yield and its components in cumin breeding programs. therefore, different multivariate statistical analysis was performed on plant characters in cumin to determine the relatio...
The phenomena of "graying" of population which was started in 20th century will continue in the next. It confronts the world with new challenges in the realms of health economy, politics, and cultural issues which are very difficult to overwhelm. The problems arising of this phenomena must be welcome, because they are indicators of upcoming development. Aging of population has occurred in devel...
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
as far as bandura’s (1977) conceptualization of the sense of self-efficacy is concerned, it is argued to be context- and even task-specific, compared to other concepts like self-esteem (brown, 2000); therefore, upon the previous research studies, related theories and definitions, and the ideas and views obtained from the interviews conducted with the scholars, the current research study aimed a...
Plant geneticists and breeders have used marker technology since the 1980s in quantitative trait locus (QTL) identification. Marker-assisted selection is effective for large-effect QTL but has been challenging to use with traits controlled by multiple minor effect alleles. Therefore, genomic (GS) was proposed estimate all markers simultaneously, thereby capturing their effects. However, breedin...
pomegranate (punica granatum l. that one punicaceae) is one of the important economical and commercial horticultural plants cultivated in arid and semiarid parts of iran. also, due to the long history of pomegranate cultivation in iran, genotypes from different regions with obvious similarities in appearance but with different names can be observed. thus, the precise discrimination between .gen...
Kin and group interactions are important determinants of reproductive success in many species. Their optimization could, therefore, potentially improve the productivity and breeding success of managed populations used for agricultural and conservation purposes. Here we demonstrate this potential using a novel approach to measure and predict the effect of kin and group dynamics on reproductive o...
