Cards

Term
What did Aristotle contribute to biogeography?
Definition

he was the first to leave written record of the question: how are organisms distributed around the world?

 

he also had the view of dynamic + changing earth

Term
What did Linnaeus (1707-1778) contribute to biogeography?
Definition

he devoloped species classification (binomial nomiclature, hierarchal, binomial)

 

Paridesial Mountain theory

* in accordance with biblical events

* immutable species; later abandoned idea for hybridization

Term
what did the Conte de Buffon (1707-1788) contribute to biogeography?
Definition

first ideas on dynamic earth and changing species

 

___'s law: areas w/ similar environment but far apart have different biotas

 

origins idea: started @ poles w/ equable climate, moved south as climate changed -> during the migration species changed and adapted to the environment (hybridization)

Term
what did Johann Rinehold Forester (1729-1798) contribute to biogeography?
Definition

first systimatic classification of biotic regions on earth

 

saw different latitude in climates --> and as lat changes/climate changes and so do species

 

tested Buffon's law

 

insights to island biogeography (less species) --> lat species gradient

Term
what did Alexander von Humboldt (1769-1859) contribute to biogeography?
Definition

documented climatic associates of plant communities

 

expanded latitudinal biodiversity gradients into elevational gradients

 

father of phytogeography

 

discovered isotherms (areas of = temp)

Term
what did Augustin de Candolle (1778-1841) contribute to biogeography?
Definition

species competition for resources as a key factor for species persistence

 

made additional observations related to island biogeo (isolation, climate, geographic history)

 

niches (first idea relating to niches anyway)

Term
what did Charles Lyell (1797-1875) contribute to biogeo?
Definition

earth climate veried significantly in past (studied fossil record)

 

Principles of Geography --> idea of uniformitarianism

 

believed in immutable species (multiple creations/extinctions and sites of creation) --> Humboldt kind of thought so too

 

 

Term
what did Darwin (1809-1882) contribute to biogeo?
Definition

what didn't he contribute? (just kidding)

 

theory of evolution by natural selection; Origin of Species (1859)

 

long-distance dispersal supporter

Term
what did Alfred Russel Wallace (1823-1913) contribute to biogeography?
Definition

developed theory of evolution at same time and independently from Darwin but Darwin published first

 

developed numerous biogeographic principles (17, in textbook)

 

father of zoogeography

 

took theories from other people and tested them

 

_____'s line: between Bali and Lombok, Austrailian and S.E. Asian species split, couldn't have been a land bridge

Term
what was the argument between the extensionists and the dispersionists?
Definition
land bridges vs long-distance dispersal events
Term
summary of the 19th century biogeo history
Definition

Darwin's theory of evolution by natural selection

 

multiple biogeographic patters documented and interpreted (e.g. ecogeograpic rules)

 

better support and delineation of biogeographic regions

Term
disjunction
Definition
when one species splits to more than one species bbecause of climate/geographic/other event
Term
What did Alfred Wegner (1880-1930) contribute to biogeo?
Definition

continental drift (first introduced by Antonio Snider-Pelligrini in 1858)

 

not widely accepted until the 1960s (didn't have a mechanism)

Term
what did Ernst Mayr (1843-1969) contribute to biogeo?
Definition

biological species concept --> group of individual that can reproduce amongs themselves and not with other groups

 

insight into mechanisms of allopatric speciation --> a barrier is created, species split and evolve into other species

Term
what did George Gaylord Simpson (1902-1984) contribute to biogeography?
Definition

described origin, dispersal, radiation, decline of land vertebrates

 

studied intercontinental vertebrate migration

Term
what did G.E. Hutchinson (1903-1991) contribute to biogeography?
Definition

multidimensional niche concept --> take every aspect of a niche together

 

father of limnology (study of lakes) --> worked with phytoplankton

 

 

Term
what did Robert H. MacArthur (1930-1972) contribute to biogeo?
Definition

equilibrium theory of island biogeography

 

strong emphasis on hypothesis testing

 

niche partitioning --> natural selection drifing species into diff areas

Term
what did Edward O. Wilson (1929-) contribute to biogeo
Definition

island biogeography

 

global biodiversity + coservation

 

sociobiology --> conserve as many species as possible, evolution is the story we want to tell

Term
20th century summary
Definition

sig. advances in evolutionary biology driven by biogeography and paleontology

 

dev. of basic ecological concepts

 

studies focusiong on single taxa instead of whole communities

 

ecological biogeography

Term
Second 1/2 20th century summary
Definition

continental drift accepted

 

ecological biogeography well established

 

equilibrium theory of biogeo

 

phylogenetic methods

 

multiple tech advances
