    Study Notes

    Taxonomical Aids

    • Herbarium: a collection of dried, pressed, and preserved plant specimens with labels indicating date and place of collection, English and local names, botanical names, and collector's name.
    • Botanical garden: a specialized garden with collections of living plants, used for identification purposes, with plants labeled with botanical/scientific name and family.

    Museums

    • Collections of preserved plant and animal specimens used for study and reference.
    • Zoological parks: protected environments for wild animals, used to study food habits and behaviors, with animals provided with natural living conditions.
    • Specimens preserved in containers with preservative solutions.

    Catalogue

    • A list that methodically enumerates all species found in a particular place.
    • Monograph: a complete global record of a taxon.
    • Manual: a record of species found in an area, providing ecological information.
    • Key: a tool used to identify an unknown organism.

    Taxonomy

    • Steps involved in modern taxonomy:
      • Characterization: describing morphological and other characters.
      • Identification: determining similarities with already known organisms.
      • Classification: placing the organism under a particular taxa or category.
      • Nomenclature: giving a proper scientific name.
    • Taxonomic categories: Species, Genus, Family, Order, Class, Phylum, Kingdom.

    Systematics

    • Study of evolutionary relationships among organisms.
    • Involves taxonomy, nomenclature, and morphology.
    • Importance: identifies, names, and describes organisms, and describes evolutionary relationships.

    Nomenclature

    • Two major codes for naming organisms:
      • International Code for Botanical Nomenclature (ICBN) for plants.
      • International Code of Zoological Nomenclature (ICZN) for animals.
    • Binomial nomenclature: a two-term system consisting of a generic name and a specific epithet (e.g., Mangifera indica).
    • Rules of binomial nomenclature:
      • Biological names are in Latin or Latinized.
      • The first word represents the genus, and the second component is the specific epithet.
      • Both words are underlined or in italics to indicate their Latin origin.
      • The genus starts with a capital letter, and the specific epithet starts with a small letter.
