Using a database of 2510 measurements from 287 species, we assessed whether general relationships exist between mass-based dark respiration rate and nitrogen concentration for stems and roots, and if they do, whether they are similar to those for leaves. The results demonstrate strong respiration-nitrogen scaling relationships for all observations and for data averaged by species; for roots, st...
Introduction Taxonomy classes are often taught that we as systematists are concerned with grouping and ranking. We are actually concerned with two levels of grouping: the grouping of individuals (into species), and the grouping of these "groups of individuals." There are, therefore, only two categories, species and groups of species (Nelson and Platnick, 1981). If we strive to make our species ...

Woody plants host diverse communities of associated organisms, including wood-inhabiting fungi. In this group, host effects on species richness and interaction network structure are not well understood, especially not at large geographical scales. We investigated ecological, historical and evolutionary determinants of fungal species richness and network modularity, that is, subcommunity structu...
Varied floristic works relevant to Kashmir Himalaya were thoroughly examined compile taxonomic contributions of various taxonomists viz. a diversity in gymnosperms this region. Extensive field surveys and standard methods used locate, collect, identify prepare an updated list the target group. A total 25 species belonging 13 genera 6 families 4 orders have been documented from Himalaya. Wild ar...
