ENV 101

Wednesday 21 February

Species – Populations – Biomes – And Biodiversity

·      Oral Presentation?

·      January Term 2008 Trips tonight 7pm in Lawson

·      EAT retreat March 3-4

·       First Exam on Monday – Look at Template

 

 

·       Ethics – how environmental ethics have been clarified

·       The Arts – how Environmental history can be revealed by a review of past and current visual, textual and tactile art

·       Matter and Life – elements, cycles and energy exchange

·       Species – from populations through to the planet

·       Biodiversity – the energy webs

 

ETHICS >> SCIENCE   >>   POLICY

                                                                                                                                         

Biotic Potential v. Carrying Capacity

 

 

ENVIRONMENTAL INFORMATION SITE  and  SAND COUNTY ALMANAC

 

 

 

Food Chains and Food Webs  - Linear v. Nonlinear

 

Mutualism >>> Commensalism >>> Predation >>> Competition (Intra or Inter)

Polaris, ANWR and Forest Issues:

 

Biomes – and complexity

o     Intra and Inter Biome

o     Intra and Inter Species

o     Chain v. Web Issues

 

 

INCREASING COMPLEXITY OF RELATIONSHIPS AMONG SPECIES…and their actions

 

 

BIOMES - similar terrestrial ecosystems spread out over the planet.   PowerMap

Chaparral Mediterranean

Tropical rain forest

Tropical deciduous forest

Temperate Deciduous and Coniferous Forest

Tropical savanna woodlands

Tropical woodland and thornscrub

Montane Communities  

Tundra

Desert and semi-arid communities

Boreal Coniferous Forest

Mediterranean Scrub and Woodland Hardwood - Conifers

Temperate Grassland

Cold Deserts and Glaciers

 

(Biased – this is ONLY the land biome list)

II.  Forest Environments

Wilderness and Tundra

Cold, Treeless, Permafrost, HIGH ENERGY VARIANTS

 

Permafrost

Wilderness and Tropical Forests

Lowland Forest versus Upland Forest

Lowland Forests = Closed and Open

Closed – Tropical Rain and Tropical Moist Forests

Open – Tropical Dry Forests and Tree Plantations

Upland – Unclassified Forests - Clouds

 

 

 

 

Food Chains and Food Webs  - Linear v. Nonlinear   and Antarctica

 

 

 

Antarctic Ocean Food Web and GAIA!?!?!?

Biological Communities

Evolution ….or Intelligent Design

WE WILL TALK ABOUT EVOLUTION HERE –

But consider…page 53 Galapagos Island Finches and wood warblers

And page 115 – Exotic/Invasive Species

 

 

Evolutions – adapt, natural selection, habitat and niche in it

Species Interacting – Predation, Competition, Symbiosis (commensalisms, mutualism), Defensive, (Mimicry)

·       Productivity

·       Diversity    = # of species in Community v Abundance of individual population

·       Complexity = Number/trophic level

·       Resilience =   K    Or R populated

·       Stability = dN/dt = rN         biotic potential J…..vs S curve due to enviro resistance

·       Structure = Patterns of Organization

 

Communities in Transition

 

 

 

 

 

 

ENERGY and trophic level transfers – delicate, complex, inefficient balance (but “natural” & never “Wasted/Lost”)

ANWR – & Tundra/Permafrost Natural impacts…and Human impacts

 

 

 

ANWR

Arctic National Wildlife Refuge

§       What are some of the species (besides humans) that are part of ANWR?

§       What is “ten-oh-two” (or Section 1002)?

§       What are some of the other media (water, soil, air) issues that are part of the ANWR story?

§       Who are some of the actors (groups, individuals) involved in the determining what happens in ANWR?

ISSUES  & Actors IN  ANWR
