Ecological Niche Modeling (16)
these plants dont grown in north america, but have been introduced
naturally, the plant grows in china and japan, so were are the
corresponding places in north America where these pants will grow? So
you look at the niche ( precipitation + other physical conditions) in its
native continent and see where these corresponding conditions will be
in north America.
This reasoning is used to explain plant distribution with respect to
climate change
Core Ideas in Physiological Ecology( 17)
organisms need to maintain homeostasis… its important that bodies
remain within the temperature range.
(22) Siberian tiger
- broad ranges that can adjust to various climates, can live in steaming
rainforests and brutal winters
(23)
- coyote is actively expanding its range, has to moved to Alaska. (more
abundant)
- well in deserts, forests, and in snow [ very dynamic and successful]
25- if the surface is moist, there ill be evaporation of water, provides for
strong cooling effect [ convection]
26- size matters
-as objects get larger, they will tend to equilibrate slowly
- the bigger the body is the more interia it takes
28- elephant, largest animal, lives in africa which is hot not cold
however, mammoths, a while ago, did live in cold environments, now we
dont find elephats in cold environments becausehuman huntes them
out, but they can in fac survive there
