Biodiversity From Wikipedia‚ the free encyclopedia Coral reefs are amongst the most diverse ecosystems on earth. Rainforests are an example of biodiversity on the planet and typically possess a great deal of species diversity. This is the Gambia River in Senegal’s Niokolo-Koba National Park. Biodiversity is the degree of variation of life.[1] It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation‚ ecosystem variation‚ or species variation

Holism Not to be confused with -holism. 2 Science Holism (from Greek ὅλος holos “all‚ whole‚ entire”) is the idea that natural systems (physical‚ biological‚ chemical‚ social‚ economic‚ mental‚ linguistic‚ etc.) and their properties should be viewed as wholes‚ not as collections of parts. This often includes the view that systems function as wholes and that their functioning cannot be fully understood solely in terms of their component parts.[1][2] Main article: Holism in science Social scientist

Evolution Unit: Objectives AP Biology Upon the completion of the textbook readings in Chapters 22-26 you should be able to: Chapter 22 1. Explain how the principle of gradualism and Charles Lyell’s theory of uniformitarianism influenced Darwin’s ideas about evolution. The basic idea of natural selection is that a population of organisms can change over the generations if individuals having certain heritable traits leave more offspring than other individuals. The result of natural selection

that‚ illuminance levels are important for pollination in plants like H. rosa-sinensis as lower levels could mean that they will not be spotted by hummingbirds. Given that H. rosa-sinensis is solely dependent on visual attraction2‚ and mostly one pollinator for pollination‚ I was interested to see if H. rosa-sinensis displayed an adaptive response to changes in illuminance levels to increase pollination chances. This led me to a research question‚ “How do different levels of illuminance affect anthocyanin

Abstract Eight global crises – human economy‚ climate change‚ exponential human population growth‚ ecological overshoot‚ biotic impoverishment and the reduction of biodiversity‚ renewable resource depletion‚ energy allocation‚ and environmental refugees – affect each other and affect and are affected by the biosphere. Some‚ perhaps all‚ are close to tipping points that‚ if tipped‚ will result in irreversible change. And yet‚ no sense of urgency is apparent. If any one of the eight interactive crises
