"Elevational Gradients in Species Richness"

Download file to see previous pages Decreasing richness, low plateau, low plateau with mid elevational peak, and mid elevational peak were found to describe patterns of species richness with elevation.
Each pattern defines the ecology of each classified group. However, very little analysis on microbe diversity is included in the patterns evaluation. This could have been affected by various methodologies used in the study scale and data sampling. While local scale covers one elevational gradient and regional scale covers fields from the whole region, the sample site should not focus on one portion of gradient truncation of the mountain. Collecting a large number of samples would make prediction of species richness more relevant.
The hypotheses on elevation species richness are based on, space, climate, biotic processes, and evolutionary history. According to SAR description of space, increase in area leads to relative increase in the number of species. This shows that diversity and elevation area have a very close relationship. Climate wise, productivity is controlled by climatic conditions. The condition affects population by controlling individual numbers hence showing that species richness and diversity have a positive relationship too. The relationship between diversity and biotic processes such as habitat heterogeneity, complexity, and diversity in this case has been estimated. Therefore, the hypotheses predict that areas with low extinction and high speciation are diverse.
In my opinion, the article and the topic are perfectly related since knowing about elevational patterns in species richness is essential in the study of diversity. The topic indicates elevation gradients clearly also discusses the effect of latitude as well. I particularly like the methodological discussion part because it compares different methods used. It also points out the benefits and the drawbacks for each. ...Download file to see next pagesRead More
