This PPT will help you to know more about the topic - "Taxonomical Aids".

1. Taxonomical
Aids

2. Introduction
Taxonomical aids are the collections of samples or preserved organisms which help in
extensive research for the identification of various taxonomic hierarchies

3. • An essential process, because: taxonomic categorization helps in identifying many
organisms necessary in various fields like agriculture, industries, bio resources, etc.
• Used for identification and classification of an organism, and information gathered is
stored along with the specimens
• Main source which helps us in studying the relative level of a group of organisms,
their taxonomic hierarchy and taxonomic rank
Introduction
Taxonomical aids are the collections of samples or preserved organisms which help in
extensive research for the identification of various taxonomic hierarchies

4. They are required for:
• Taxonomic studies of various species of plants, animals, and other
organisms, which require correct classifications and identification
• Identification of organisms requires laboratory and field studies

• HgCl₂ is used to protect specimens from pests and insects
• These specimens, with a descriptions on
sheets, become a store house for future
use
• Herbarium sheets carry a label providing
information about:
 date and place of collection
 English, local and botanical
names
 family and collector’s name

8. Specialised gardens that contains collection of living plants for reference
• Plant species in these gardens are grown for identification purposes
• Each plant in garden is labelled indicating its botanical or scientific
name and its family

10. Collections of preserved plant and animal specimens
for study and reference
Have collections of skeletons of animals; plant and
animal specimens preserved as dry specimens
• Biological museums are generally set up in the
educational institutes like schools and colleges
• Specimens are preserved in containers or jars in
the preservative solutions
• Killing and pinning larger animals like birds and
mammals are stuffed and preserved
• Insects are preserved in the insect boxes

11. Places where wild animals are kept in protected environments under human care
and which enable us to learn about their food habits and behaviour

12. Monographs
Manuals

13. Taxonomical aid used for identification of plants and animals based on the
similarities and dissimilarities
Key
• Based on the contrasting characters generally in a pair called as the couplet
• Represents choice made between two opposite options that results in acceptance
of only one and rejection of the other
• Separate taxonomic keys are required for each taxonomic category such as family,
genus and species for identification purposes
• Keys are analytical in nature and each statement present in the key is called a lead
