بذه عن الكتاب:

• The terms ‘weed’, ‘invader’, ‘colonist’, ‘exotic’, ‘non-native’ and others are often used in
overlapping and conflicting manners.
• Weeds are classified based on their impact on human activities. Therefore, the effect of
a weed is difficult to quantify because it depends on our personal biases.
• Definitions and classifications in ecology are often arbitrary and made for purely practical reasons. They do not necessarily reflect any innate structure of nature.
• Ecology can be studied at a variety of levels. In this book, we focus on population and
community ecology.
• Weed ecology provides a basic understanding of the distribution and abundance of
weeds in natural and managed systems. In the long term, it may change our attitudes and
perceptions towards weeds and alter the way we manage them.

Biologically

Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.


Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:

Anatomy
Botany
Biochemia
Biogeography
Biofisia
Cytology or cell science
Ecology or environmental science
