BIO 263 Lecture Notes - Lecture 16: Habitat Fragmentation, Metapopulation, Population Pyramid
Document Summary
As population density increases it causes population mortality to decrease and general. Birth rates also decrease and density increases. Small pockets of habitat that are connected together to form a population. Can occur with birds on islands where they can move easily from each island to another. Exists more in more common in species we are interested in conserving. Over population can be stable because migrants recolonize empty habitat. Caused by habity fragmentation due to the deforestation of bamboo that was occurring in south china. Deforestation of bamboo lead to patchy areas where pandas can actually. How does age structure affect population growth live. Proportion of individuals at each possible age influences population growth. Depicts #of males and females of each age group. In humans developed countries tend to have much more uniform age pyramids while developing countries tend to have more bottom heavy population. Classic example is in hare and lynx.
