Floristic Diversity in the Kashmir Himalaya: Progress, Problems and Prospects
The Kashmir Himalaya, being nestled within north-western folds of the Himalaya, harbours a rich floristic diversity of immense scientific interest and enormous economic potential. Though scientific studies on the floristic diversity in the Kashmir Himalaya have been started about two centuries ago, yet they fall short of the requirements needed urgently in the post-Rio Summit. In fact, at the s...
متن کاملGrazing Response of Topsoil Characteristics in Temperate Rangelands of Kashmir, Himalaya
The superficial strata of ground have been perennially exposed to the action of natural agents such as heat, cold and water. However, grazing agent was not different from them when soils were investigated from temperate rangelands of Kashmir and caused the soil compaction, soil structure degradation and loss of soil organic C and C/N ratio. Soils from three grazing intensities were investigated...
متن کاملEvolution and biogeography of gymnosperms.
Living gymnosperms comprise only a little more than 1000 species, but represent four of the five main lineages of seed plants, including cycads, ginkgos, gnetophytes and conifers. This group has huge ecological and economic value, and has drawn great interest from the scientific community. Here we review recent advances in our understanding of gymnosperm evolution and biogeography, including ph...

متن کاملThrips pollination of Mesozoic gymnosperms.
Within modern gymnosperms, conifers and Ginkgo are exclusively wind pollinated whereas many gnetaleans and cycads are insect pollinated. For cycads, thrips are specialized pollinators. We report such a specialized pollination mode from Early Cretaceous amber of Spain, wherein four female thrips representing a genus and two species in the family Melanthripidae were covered by abundant Cycadopite...
