Module 17: Niches and species distribution
Mod 17: niches and species distribution Check this out: You'll see another like this in population distributions... Range of tolerance-where it can survive Fundamental niche-happy place Realized niche-de facto place Distribution-areas where they live (we'll s...
Module 18: Abundance and distribution
Module 18-abundance and distribution Start with this: A crude example of this might be: individual-you population-HPA students community-HPA ecosystem-education biosphere-the world or: some rabbit individual some of the rabbit's friends, a population of rabb...
Module 19: Growth Models
Module 19: growth modelsImagine you are a happy bacteria, or rabbit, with lots of food, land and no predators. Your population growth curve might look like this: This is called exponential growth, or "J shaped growth"Note that it has no end, or limiting factor...
Module 20: Community ecology
Module 20: Community ecology Competitive exclusion principle: two species competing for the same resources cannot co-exist, leads to... Resource partitioning: time, space, type of food (one species picks one, the other survives) Screenshot 2024-11-14 at 14.43....
Module 21: Community succession
Module 21: Community Succession Primary succession: From bare rock, no soil: (e.g. lichen) These hold moisture and some sort of matrix (e.g. soil) so that others can then grow You might imagine driving from the Kohala coast up to Waimea, seeing bare lava along...
Module 16: Speciation
Geographic isolation (e.g. Galapagos) also found where we disturb natural habitats with roads This causes Allo (other) Patric (father) speciation Eventually reproductive isolation will result: different breeds will not be able to procreate There is another mor...
Module 22: Human Populations
Every day: 2.1 million infants are born (2,100,000) 800,000 people die result: global population increases by 1.3 million (2.1-0.8 = 1.3) this assumes no aliens landing, nobody going to Mars (yet)We describe this as a population growth rate in percent this way...
Module 23: Demographic transition
From the semester exam: eras.png Back to Demographics... Demographics is the study of people Check this out: Screen Shot 2022-10-23 at 7.24.03 AM.png What does this mean?Phase 1: many babies, most die, short lifespans=> low population (e.g. US and Britain befo...
Module 24: Earth science
Module 24: Earth Science Key points: All elements up to Iron on the periodic table came from the big bang Earth was formed from materials created by first generation stars going supernova The core of the earth is made up of a rotating solid core surrounded by ...
Module 25: Soils
Rocks Module 25 Igneous (fire) Sedimentary (layers) Metamorphic (Kafka rocks, just kidding: changed by heat and pressure) Igneous= directly from magma, and can be either basalt (low melting point, like our island or oceanic plates) or granite (lighter, what co...
Module 31: Food
Recall our main themes: energy->water->food->culture Food! Three main groups: Proteins: always include Nitrogen Carbohydrates: CHO in chains (starches) or simple (sugars) Fats: CHO again, but in a special branch structure (glycol backbone) that is good for en...
Module 32: Food production
Mod 32: Industrial Farming (and fishing) Agribusiness: just what it sounds like, the larger conglomerates taking over instead of smaller privately owned family farms. Often use monoculture crops to increase profits (economy of scale), as well as patented seed...
Module 33: Sustainable food production
Mod 33: Sustainable agriculture (fishing too) Desertification (see above) intercropping vs. monocropping, see "the three sisters" Contour cropping: saves space, reduces runoff, preserves top soil (e.g. our garden, most of Asia) No-till ag: same idea, retains o...
Module 26: Water availability
Recall: Energy->Water->Food->Culture (Also Chapter 12 in Froggie book) Water: key points: What is it, where is it: freshwater saltwater how it moves aquifers and reservoirs impact of climate change water wars What is it, where is it?Where is the water? Note: ...
Module 27: Humans and water
This module is all about controlling water: Primitive societies were often cited on rivers: Why? Levees are walls built to contain the rivers when they flood, particularly in flatter areas, fed by melting glaciers or snow melt. Most of the Netherlands (includi...
Module 28: Humans and water in the future
Water footprint: the amount of water used per capita (per head) in a country, including irrigation, industry and residential use. Check out these two images: Screen Shot 2022-11-26 at 2.15.35 PM.png Screen Shot 2022-11-26 at 2.18.40 PM.png What do you notice a...
Module 06: movement of energy
Module 6: Movement of energy Biosphere-all life Producer (also primary producer) gets energy from sun or heat directly, also known as autotrophexample: grass Photosynthesis: CO2 + water + energy (heat or light) -> sugars (CHO)Reverse process is respiration: Su...
Module 07: movement of matter
Module 7: Movement of MatterBiogeochemical cycles: bio=life geo = minerals chemical = chemical cycle = something that rotates Hydrologic (water) cycle:Heat provides energy for evaporation,Plants secrete water as transpiration,Condensation is collection of wate...
