The distribution range of species and climatic variables along elevation have been used in evaluating the elevational diversity gradients (EDG).

The species richness–climate relationship is a significant concept in determining the richness patterns and predicting the cause of its distribution.

The rise of angiosperms pushed conifers to decline during global … During meiosis, reproductive spores are released into the air from structures' called sporangia. Sporophytes are diploid multicellular generation – that is, they contain two sets of chromosomes. WebGymnosperms are vascular plants, which means that their life cycle is dominated by sporophytes.
