SPECIES DIVERSITY IN POOL AND RIFFLES OF A LOTIC TROPICAL SYSTEM Abstract This study looked at species adaptations to different substrate type‚ current velocity‚ dissolved oxygen and depth that allows for the specialized utilization of the microhabitats found and how this was responsible for similarities and differences in species diversity in pools and riffles. The riffle was seen as the more diverse mesohabitat. Of the 47 species found‚ the riffle had 37 of these organisms present. The

One reason that keystone species have the biggest impact on the high degree diversity is that keystone species can control the amount of herbivores which can create different plants like in the video “Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades” In the video it talks

According to Zimmer‚ de-extinction is defined as‚ “The notion of bringing vanished species back to life”‚ and he elaborates the pros and cons of actually completing this ordeal (31). Reading the differentiating views on the subject is very interesting‚ and caused me to think more and more as to if bringing back the extinct species is for the good or bad of our world. But as a firm believer
