Document Summary

Spent most of his time in south america his job was to make observations of natural history plants. ,animals, geology, fossils, flora and fauna of oceanic islands. Oak woodland in england characterized low species diversity like canada. Very high species diversity of plants and animals compared with temperate zones. Many more biotic (living things interacting) interactions, especially coevolved mutualisms between plants and animals. Year-round warmth results in rapid growth of insect and microbial populations, hence pest and disease pressures on plants are more intense. Tropical forests are different from temperate forests in that because there is so much species diversity, the distances between individuals of the same tree species are large. spatially segregated. Answer: in the tropics, there are animal pollinators, in temperate forests: wind: pollen is moved from tree to tree especially in the spring when there is no canopy. Wind is not a good mechanism in tropical forests because there is always a dense canopy of trees.
