adaptative radiation - diversification of a group of organisms into forms filling different ecological niches allopatric speciation - aka geographical isolation: biological pops of the same species become isolated from each other to an extent that prevents or interferes with gene flow allopolypl...

"Asteroid impact" - Influence that humans have on earth Satellite imaging highlights the lights during the night Light = continuing story of manhattan Human influences on biodiversity and conservation ~2M early hominind ancestors moved - north out of Africa ~70M first Homo sapiens moved - Nor...

3 mechanisms for prokaryot genetic recombination - 1.)Transformation 2.)Conjugation 3.)Transduction Absolute dating - -Radioactive isotopes decay over regular annual time periods (half-lives) -C14 5,700 yrs - radioactive isotopes vs stable isotopes -stable isotopes stay the same after the orga...

Age structure - Distribution of individuals across age categories Alfred Russel Wallace - Established biogeography Amenalism - One species is harmed, other is unaffected Antagonistic interactions - One species benefits, other is harmed (e.g., predation, herbivory, parasitism) Any environment is...

Adaptive Radiation - An evolutionary pattern in which many species evolve from a single ancestral species Allele - An alternative form of a gene. Allele Frequency - Number of times that an allele occurs in a gene pool in comparison to the total number of alleles allopatric speciation - The form...

(C P N) - C = predators search and attack probability P = number of predators N = number of prey (C P N) = consumption rate of prey Abiotic Factors - non-living chemical and physical factors (ex: temp, light, nutrient, water) Solutions are acclimation or adaptation amensalism - (- , 0) biotic ...

? Rule the world - Phytoplankton! - Fix lots of CO2, produce 90% of the Earth's O2 and help create clouds - Limited by: P, N, silica (diatoms), iron, trace elements - Could harness phytoplankton to control greenhouse gases (consume CO2 when fixing C - phytoplankton is iron limited; experiment: ...

Adaptation - A trait that benefitted an organism in a particular environment (level: individual) Allopatry - restriction of gene flow because of physical separation Physical geographic barrier: individuals, even if they wanted to, do not have the ability to mate with other group Analogy - eviden...

5 basic types of predation - carnivory, parasitism, parasitoids, cannabalism, herbivory Abiotic components - non-living chemical and physical factors(temperature, light, water, nutrients) ammensalism - one species is harmed and the other is unaffected(-,0) ex: larger tree shading smaller stature...

A macdonald - -2500m amphipods Absense of groups in deep sea - -not a result of inability to adapt -result of habitat not being suitable Abyssopelagic - -dark -below 4000m Achieving neutral buoyancy - -reduce heavy materials (increase water content) -lower density of body fluids -add lipids ...

aneurysm vs hemorrhage? - aneurysm: a blood-filled balloon-like bulge in the wall of a blood vessel hemorrhage: an escape of blood from a ruptured blood vessel cerebrovascular accident vs transient ischemic attack - stroke: a rapid loss of brain function due to disturbance in the blood supply to...
