A tribe is a group of people living under primitive condition and still not popularly known to more modern culture. There are numbers of tribes living all over India as well as various parts in the World. More than 55% of the total tribal population of India are living in central India like Bihar, West Bengal, Orissa, and Madhya Pradesh and remaining tribal population is concentrated in the Him...

The Brassicaceae is a large plant family (338 genera and 3,700 species) of major scientific and economic importance. The taxonomy of this group has been plagued by convergent evolution in nearly every morphological feature used to define tribes and genera. Phylogenetic analysis of 746 nrDNA internal transcribed spacer (ITS) sequences, representing 24 of the 25 currently recognized tribes, 146 g...

The American Indian Wars provide unusual insight into debates about group structure and military behavior. These conflicts present a cross-section of experience with a relatively high degree of unit homogeneity; it is possible to gather information on tribes that fought as well as those that did not; scholars have recorded information about the tribes’ political and economic structures in detai...

The subfamily Xylocopinae has been recognized as the most basal lineage within the family Apidae, comprising four tribes; Allodapini, Ceratinini, Xylocopini and Manueliini. Relationships among the tribes are not well resolved with morphological data. In particular, Manueliini and Xylocopini have each been placed as the most basal lineage in separate analyses of the subfamily. While relationship...

To illustrate the campaign to extend our knowledge of the charmonium spectrum, I focus on a puzzling new state, X(3872) → ππJ/ψ. Studying the influence of open-charm channels on charmonium properties leads us to propose a new charmonium spectroscopy: additional discrete charmonium levels that can be discovered as narrow resonances of charmed and anticharmed mesons. I call attention to open issu...
