Botanical Gardens From herbal gardens and exotic plants, 18th century
History to biblical times Test and grow plants for medicine, dyes, food, timber, and other economic and strategic purposes Bartram Gardens –first botanical garden in N.A. Satisfy European demand for exotic plants

Herbarium Specimens Herbarium sheets Dry mosses & lichens
Large specimens stored in boxes All kept in cabinets according to a system Herbarium at the Museum of Natural History, Paris
12
Herbaria Muséum national d'histoire naturelle (Paris) nearly 10 million specimens Ботанический институт им. В.Л.Комарова (St. Petersburg) more than 7 million specimens Royal Botanic Gardens, Kew (7 million specimens) New York Botanical Garden, (7 million specimens) Herbarium curator at the New York Botanical Garden William and Lynda Steere Herbarium
13
Zoos and Aquaria Evolved from private royal menageries
Living collections with different habitat and dietary requirements Breeding programs in place for conservation and to maintain a breeding population
14
Largest Zoological Parks
Zoologischer Garten Berlin (1844); >1,500 species Moscovskiy Zoopark (1864); >1,000 species Beijing Zoo (1906); ~1,000 species (marine and terrestrial) San Diego Zoo (1916); >800 species Columbus Zoo and Aquarium (1927); >800 species Bronx Zoo (1899); >650 species Penguin exhibit at the Zoologischer Garten Berlin
15
Classification Methods
By ecology By form By ancestry
16
Hierarchical Taxonomy of Linnaeus
THE RANKS OF OUR SPECIES KINGDOM: ANIMALIA (all living things that develop from a blastula) PHYLUM: VERTEBRATA (all animals that have articulated vertebrae) CLASS: MAMMALIA: (all vertebrates that have hair and feed their young with milk, have a single dentary and three bones in the middle ear) ORDER: PRIMATES (all mammals that have opposable thumbs, forward-facing eyes) FAMILY: HOMINIDAE (all primates that are large, >30-40 kg, tailless, and omnivorous, the Great Apes) GENUS: Homo (hominids that are bipedal with very fine body hair) SPECIES: Homo sapiens (a species of Homo that has a chin and small face)
17
All species must have a type deposited in an appropriate collection
The binomial must be unique Genus is a Latinized noun followed by a Latinized adjective Example: Homo sapiens Linnaeus (1758) Description must be published in a reputable journal.
18
Descriptions must conform to:
International Code of Nomenclature for algae, fungi, and plants (ICN) International Code of Zoological Nomenclature (ICZN) International Code of Nomenclature of Bacteria (ICNB) International Committee on Taxonomy of Viruses (ICTV)

Schools of Evolutionary Reconstruction
Evolutionary Systematics (generate phylogenetic trees) Numerical Systematics (Phenetics, generate phenograms) Phylogenetic Systematics (Cladistics, generate cladograms)
21
Evolutionary Taxonomy
Followed union of Linnaean Taxonomy with Darwinian evolution to create dendrograms reflecting heirarical structure of the accepted taxonomy.
22
Experts on groups who know both living and fossil groups were relied upon to generate the evolutionary relationships. Ernst Mayr 1904 (Germany) – 2005 (USA)
23
Numerical Taxonomy Also known as Phenetics
Also uses characterXtaxon matrix and solves to a dendrogram according to similarity coefficient
24
CharacterXTaxon Matrix
25
Rise of Cladistics Founded by Willi Hennig
Difference between primitive and derived characters very important This system is very powerful when coupled with molecular data , Germany

The PhyloCode The International Code of Phylogenetic Nomenclature, known as the PhyloCode, which is governed by the International Society for Phylogenetic Nomenclature (ISPN), is developing a formal set of rules governing phylogenetic nomenclature. Currently, it regulates the naming of clades, but species names are left up to the rank-based Nomenclature codes: International Code of Nomenclature for algae, fungi, and plants (ICN) International Code of Zoological Nomenclature (ICZN) International Code of Nomenclature of Bacteria (ICNB) International Committee on Taxonomy of Viruses (ICTV)
36
Types of Clades Used in the Phylocode
37
Node-Based The clade originating with the most recent common ancestor of A and B or the least inclusive clade containing A and B. Mammalia: Clade originating with the most recent common ancestor of humans, Homo sapiens Linnaeus 1758, and platypuses Ornithorhynchus anatinus Shaw 1799
38
Branch-Based The clade containing A and all organisms or species that share a more recent common ancestor with A than with Z or the most inclusive clade containing A but not Z. Rodentia: Most inclusive clade containing the house mouse, Mus musculus Linnaeus 1758, but not the eastern cottontail, Sylvilagus floridanus Allen 1890
39
Apomorphy-Based The clade originating with the first organism or species to possess apomorphy M inherited by A. Tetrapoda: Clade originating with the earliest ancestor from which Homo sapiens Linnaeus 1758 inherited limbs with fingers or toes.
