Document Summary

Lecture 2 & 3:physical challenges of the environment. Animals geographic ranges usually correspond to biomes (limit to climates or vegetation), but sometimes it is also affected by other factors: Pronghorns have a broad temperature tolerance range but a narrow habitat range. Elf owls, gila woodpekers depends on cactus. Tigers can live in any habitat either hot or cold. Radiation: emission of electromagnetic energy by a warm surface. Conduction: transfer of the kinetic energy of heat between substances in contact with one another. Convection: transfer of heat by the movement of liquids and gases. Redistribution: circulatory system redistributes heat among body parts. Larger organisms tend to lose heat across their surfaces less rapidly than smaller individuals this is because the surface-to-volume ratio is smaller(v sa ). It is easier for them to maintain a constant internal environment in the face of varying external conditions. Bergmann"s rule: homeotherms tend to be larger at a higher altitude.

Prompt #3: Please provide very detailed information. Thank you.

Plants and animals do not operate independently of one another. In fact, it is how these organisms interact that often defines form and function. Ecology is the branch of biology that focuses on these species interactions with each other in the habitats that they live. In light of the many human-induced changes to the environment, it would be impossible to study ecology without accounting for anthropogenic effects. Assume you are an ecologist studying local flora and fauna in San Diego. Describe the effects of human development in a local habitat (e.g. coastal, desert, chaparral, grassland, wetland, etc.). How will continued global climate change effect species adapted to a specific environment? What conservation and management measures could be implemented to protect native species in San Diego?

Question 13

Species that are purposely or accidentally introduced to a new geographical region

Answers:	frequently form hybrids with native species
	die out quickly
	can become serious pests by killing the native species
