4.1 Describe how evolution produces species diversity. 4.2 Discuss how species interactions shape biological communities. 4.3 Summarize how community properties affect species and populations. 4.4 Explain why communities are dynamic and change er vo time. CHAPTER 4 The relatively young and barren volcanic islands of the Case Study: Darwin’s Voyage of Discovery 4.1 Evolution Produces Species Diversity Natural selection leads to evolution All species live within limits The ecological niche is a species’ role and environment Speciation maintains species diversity Evolution is still at work Exploring Science: New Flu Vaccines Taxonomy describes relationships among species 4.2 Species Interactions Shape Conversely, understanding the ecology of communities of species requires appreciation of evolution and the role of history. Darwin, whom many view as a founder of ecology, appreciated that “plants and animals, most remote in the scale of nature, are bound together by a web of complex relations” (ref.

Plants and animals have well established interdependence for reproduction. species:mosses • Species can facilitate/or inhibit the entry of other species into the community • Can reach a climax community CHAPTER 4 Evolution, Biological Communities, and Species Interactions 75 Case Study attributes are more likely to live and reproduce than those less well-endowed. Because the more fit individuals are especially successful in passing along their favorable traits to their offspring, the whole population will gradually change to be better suited Evolution, Biological.

How are species interactions structured in species-rich communities

It includes all physical, chemical, and biological conditions a species needs to live and reproduce in an ecosystem. It can also be defined by the ranges of conditions and resources within which the organism can live. § Generalist species have broad niches.

And these new species create new communities that have unique characteristics from the other. Facultative symbiosis is when the species live together by choice.

Mutualistic interaction Professor Sapolsky points out the silliness of identifying biological elements as amazing based simply on their congruence with necessity since the animal, be it Professor Sapolsky continues his analysis of behavioral evolution, examining In essence, having males is a "risky strategy" in a tournament species Professor Sapolsky moves on to discuss criticisms of the ideas of evolut Key Takeaways · The capacity for learning is grounded in early brain development.

Natural Selection - Members of a population More species are becoming extinct today than at any time since dinosaurs were wiped off the face of the Earth by an asteroid 65 million years ago. Yet this bio-Armageddon, caused mainly by humans, is greeted by most of us with a yawn and a shrug. 2013-12-04 · Case Study: Darwin’s Voyage of Discovery 4.1 Evolution Produces Species Diversity Natural selection leads to evolution All species live within limits The ecological niche is a species’ role and environment Speciation maintains species diversity Evolution is still at work Exploring Science: New Flu Vaccines Taxonomy describes relationships among species 4.2 Species Interactions Shape The interaction between fresh and saline water at the estuary may also be affected.
