Conservation of biology ppt

Origin of New Species

speciation: process of new species formation where one original species evolves into one or more new and distinct species

Patterns of Diversity

factors affecting local/regional biodiversity o amount and annual pattern of solar radiation o amount and annual distribution of precipitation o average annual temperature and seasonality

Should biodiversity be preserved O Biophilia?

Ethical Principles diversity of species and ecosystems should be preserved o biophilia:

humans may have genetic predisposition to like biodiversity untimely extinctions of populations and species should be prevented .

Wildlife management of game animal populations to provide opportunities for hunting, fishing, and observation.
Conservation Biology? .

Why is conservation biology important?

Chapter 1:

increased material consumption

increased countries develop and industrialize -human population growth -> huge impact on environment .
