Document Summary
Reduce range or kind of adaption one might see. Constrain adaptive responses ( rabbit strong relationship with environemtn and weather) Mechanical constraint rabbit pika likes mountain slopes, large ears delicate for slopes. Ecology: factors determining distribution and abundance of organisms: distribution: geographical range, range maps used (plot positions of many sightings, ranges are stable parts of species. Used in bird books for identification and morphology color etc. Range limiting factors: hierchal (climate with physiology interplay) Biomes: sets of characteristic organisms in places with different climate: range limits correspond to biomes, general rules: More rain > taller vegetation, more species rich and productive. Warmer places have more complex vegetation than colder. Seasonality of temperature and precipitation is important (summer rains versus winter rains) Soil ecology: soil characteristics contribute to the differences among biomes. Tuesday, october 25, 2016: whether water is available, mineral nutrients contained, as soil influences vegetation and vice versa. Generous concentrations of dissolved ions plants need for growth.
